Ukufakwa nokulungiswa kwamaphutha kwe-valve yokulungisa kagesi kuyizinto ezimbi futhi ezinenzuzo ekuthuthukisweni kokulungiswa kukagesi-i-valveimboni ezweni lakithi
Enqubweni yokukhiqiza kanye nokunikezwa kwamandla, ama-valve amaningi amasango ajwayelekile, ama-disc valves nama-butterfly valves we-hydraulic asetshenziswa emabhizinisini okukhiqiza, ikakhulukazi emadolobheni amakhulu. Balawula ukukhiqizwa nokukhiqizwa kwamanzi okuphuza, okuyisisetshenziswa esibalulekile sezinkampani ezihlinzeka ngogesi. I-valve yesango likagesi iqukethe i-valve yokulawula kagesi kanye nezinsiza ezisekela i-valve yesango. Isetshenziselwa ukusebenza ukuvula nokuvalwa kwe-valve yesango. Ingasetshenziswa khona lapho futhi ingasetshenziswa ukude.
Amabhizinisi akhiqizayo, ikakhulukazi izinkampani ezihlinzeka ngamanzi emadolobheni amakhulu, asebenzisa ama-valve amaningi ajwayelekile esango, ama-disc valves, ama-butterfly valves, njll., ekukhiqizeni nasekunikezeni amandla kagesi, ukuze akwazi ukukhiqiza nokukhiqiza amanzi okuphuza, okuyi-hydraulic butterfly valves, njll. okokusebenza okubalulekile kwezinkampani eziphakela ugesi. Kunenombolo enkulu yama-valve esango asetshenziswa kuzo zonke izinhlobo zama-valve esango. Iqoqwa yinethiwekhi ye-valve yepompo yase-Chinese futhi izokufundisa ukulungisa idivayisi kagesi ye-valve elawulayo kagesi ngesandla.
I-valve yesango likagesi iqukethe i-valve yokulawula kagesi kanye nezinsiza ezisekela i-valve yesango. Isetshenziselwa ukusebenza ukuvula nokuvalwa kwe-valve yesango. Ingasetshenziswa khona lapho futhi ingasetshenziswa ukude. I-valve yokulawula kagesi yakhiwe injini, isinciphisi, indlela yokunciphisa i-torque, indlela yokulawula ukuhlelwa kwe-stroke, indlela yokuguqula ugesi yohlobo lwemanuwali, indlela yokuvula idigri yokumaka kanye nephaneli yokulawula imishini kagesi. Uma ukulungiswa kwedivayisi kagesi ye-valve yesango kagesi kungenangqondo, impilo yesevisi ye-valve yesango kufanele incishiswe. Izingozi ezingathi sína ezifana ne-gate valve pig iron casing breaking control motor burning kanye negumbi lokumpompa lezikhukhula. Ngakho-ke, ukuze kuqinisekiswe ukunikezwa kwamandla okuphephile nokungaphazanyiswa, kuyadingeka ukulungisa idivayisi kagesi ye-valve yesango likagesi kahle ukuze kuqinisekiswe ukuvulwa okuphumelelayo nokuvalwa kwe-valve yesango kagesi. Imininingwane elandelayo yezindlela ezimbili zokulungisa i-valve yesango likagesi:
1. Ukulungiswa kwendlela yokunciphisa ithoshi
Ama-valve esango likagesi asetshenziswa ezindaweni ezihlukene ngenxa yomehluko wengcindezi kuzo zombili iziphetho ze-valve yesango noma umehluko wokucindezela komoya (i-valve yesango ivaliwe), indlela yokunciphisa i-torque kufanele ilungiswe ngendlela efanele. Lapho kusetshenziswa i-valve yesango likagesi kuzo zombili izinhlangothi zokucindezela kwe-azimuthal noma umfutho womoya endaweni ephansi, indlela yokunciphisa i-torque kufanele ilungiswe ibe yi-torque ephansi, imikhiqizo yochungechunge lwe-HZ (njengoba kukhonjisiwe kuMfanekiso 1), imikhiqizo yochungechunge lwe-Z (njengoba kuboniswe Emfanekisweni. 2) noma imikhiqizo yochungechunge lwe-ZB (njengoba kukhonjisiwe kuMfanekiso 3) i-valve elawulayo kagesi, idinga kuphela ukulungisa ipuleti lokulungisa elikhawulela itorque kanye nebanga phakathi kwepuleti elinyakazayo ukuze kuzuzwe (ukulungiswa okuningiliziwe). Ipuleti lerula limakwe ngerula, futhi lapho inani lesikali liyanda, likhulu inani letorque. I-valve yesango le-valve elawula ugesi ivaliwe lapho umehluko wengcindezi phakathi kweziphetho ezimbili noma ingcindezi yomoya ngaphezulu, inani le-torque elilungisiwe kufanele libe ngaphezulu, ngokuphambene, libe lincane. Uchungechunge olungenhla oluningi lwendlela yokulungiswa komkhiqizo luyafana. Lapho ulungisa uchungechunge lwe-valve elawulayo kagesi ye-ZD (njengoba kukhonjisiwe kuMfanekiso 4), susa isembozo eseceleni segobolondo, lungisa indlela yokukhawulela i-torque, khulula isikulufu sokulungisa kusikulufa sokulungisa, khulula isikulufu sokulungisa, khulula inkinobho yokucindezela i-torque spring, futhi ufake engxenyeni evulekile, futhi uqinise isikulufu sokulungisa kusikulufa sokulungisa, lungisa isikulufu sokulungisa. Qaphela ukuthi ingaphezulu lesikulufu sokulungisa kufanele liwele emzimbeni we-shaft groove. Uma phezulu kungakhombi ku-shaft groove ncamashi, inani elincane kuphela lokuzungezisa isikulufu sokulungisa sibheke esiphethwini se-torsion siyadingeka ukuze sikhombise isikulufu sokulungisa inkatho ye-shaft. Beka isembozo eseceleni bese ulungisa i-valve yesango. Uma ukuzilolonga komkhawulo we-torque, intwasahlobo ye-torsion ixega kakhulu futhi iqinile endaweni. Lokhu kungenza indlela yokunciphisa i-torque isebenze ngaphansi kwetorque ephansi ngokuqhathaniswa, ukuze kuqinisekiswe ukuthi i-valve yesango likagesi ngenxa yokwehluleka kwendlela yokulawula ukuhlelwa kohambo, noma ezinye izizathu zetorque eyeqisayo, indlela yokuma okuthembekile yetorque, futhi inqamule ugesi oshintshwayo, ivikele. i-valve ngeke ichithwe. Ivalvu yesango kagesi esetshenziswa kwezinye izindawo futhi ayidingi ukulungiswa ukuze ivaleke kakhulu, ilungiswe ohlotsheni lwezandla lokuvala bese idedela emuva izindandatho ezimbili (noma indandatho) ifanelekile, (noma awekho amanzi noma igesi efanelekile) .
Lapho i-valve yesango likagesi ifakwe endaweni lapho umehluko wengcindezi yokukhiqiza amanzi (noma umfutho womoya) umkhulu, indlela yokunciphisa i-torque kufanele ilungiswe ukuze ivumelane nokuvula nokukhansela okufanelekile. Isibonelo, i-valve yesango lokuphuma kwamanzi efakwe ekamelweni lepompo, ngemva kokuqala kwepompo ye-centrifugal, ukucindezela kokuphuma kwamanzi kukhulu uma i-valve yesango ingavulwa. Ngalesi sikhathi, ukucaciswa kwevalve yesango lokuphuma kwamanzi kuyanda, itorque esetshenziswa kakhulu ukuvula i-valve yesango. Ikakhulukazi uma kungekho ukucindezela epayipini, ingcindezi ehlangene engathwala i-valve yesango inkulu kakhulu. Ngalesi sikhathi, isiphethu se-screw torsion silungiselwa ukuvuleka nokuvalwa okuvamile kwe-valve yesango, futhi indlela yokunciphisa i-torque ayikho endaweni. I-valve yesango likagesi elisetshenziswa ekamelweni lokumpompa kufanele lilungiswe endaweni evulekile evalwe ngokugcwele, ngaphandle kwalokho kulula ukulimaza indawo ye-valve yesango okuholela ekuphumeni kwamanzi. Ngenxa yokuthi i-valve yesango kagesi efakwe kuleli phuzu iseduze ne-centrifugal yepompo yamanzi, izinga lokugeleza kwamanzi liphezulu futhi alizinzile. Ngalesi sikhathi, uma i-valve yesango ingavulwanga ngokugcwele, amanye ama-valve esango anyakaza esuka kolunye uhlangothi ngenxa yomthelela wokugeleza kwamanzi, ukuze ubuso be-valve yesango bulimale, okubangele ukugeleza kwamanzi kwe-concave groove kulimaza impilo yesevisi. we-valve yesango. Ngaphezu kokuzama ukugwema ukusebenzisa i-valve yesango likagesi ukulungisa i-valve, ngaphandle kwalokho kulula ukubhubhisa indawo ye-valve yesango. Ukwengeza, eminyakeni yamuva, ubuchwepheshe bokulawula isivinini sokuguqulwa kwemvamisa buthuthuka ngokushesha, ukulungiswa kokugeleza kwepompo kufanele kusebenzise ubuchwepheshe bokulawula isivinini sokuguqulwa kwemvamisa, ukuze kongiwe amandla futhi kuncishiswe ukukhishwa kwegesi ukuze kuthuthukiswe ukusebenza kahle kwephampu ye-centrifugal.
2 Ivalvu yesango likagesi “vula, vala” ukulungiswa kwendawo
Lungisa ukuvuleka nokuvalwa kwamavalvu esango likagesi. Ngokwemithethonqubo yokulungisa yomkhiqizi ngamunye, i-valve yesango kufanele ivalwe ngesandla engxenyeni "evalwe ngokugcwele" noma ingxenye "evulekile". Uma lokhu kudinga i-valve yesango elincane labasebenzi ukuvala nokuvula isikhathi siningi, noma sinzima kakhulu. Indlela entsha yokulungisa yethulwa lapha ngokuningiliziwe: uma ukuhlukaniswa kwesiqu se-valve yesango kwaziwa, kuyoba lula ukulungisa i-valve yesango likagesi lapho uyilungisa. Namuhla, ukuhlukaniswa kwesiqu kwevalvu yesango enezinga le-DN400-DN600 ekhiqizwa eShayina ngokuvamile kungu-8mm, kanti isikhala se-valve yesango esinomshini ongaphezu kwe-DN600 ngokuvamile singu-10mm. Uma kungenzeka, cela umkhiqizi wevalvu yesango ukuze ahlukanise isiqu. Lapho ulungisa i-valve yokulawula kagesi, uma wazi isikhundla se-valve yesango kusengaphambili, uma wazi ukuthi i-valve yesango isendaweni yonke evaliwe, kufanele ulungise ingxenye "evalwe ngokugcwele" kuqala. Okokuqala, zungeza ngesandla i-valve yesango endaweni yokuqala, njengokujikeleza okubili noma okukodwa kwesiqu. Bese uphakela amandla okushintsha bese ucindezela inkinobho ethi “Vula”. Hlola ukuguqulwa. Uma ukuchezuka kwesiqu se-valve kuhambisana nokuguqulwa kwesiqu se-valve lapho i-valve ivulwa ngesandla ngokusho kwenkinobho yokuvula, kubonisa ukuthi umugqa ongathathi hlangothi we-motor usendleleni efanayo nesilawuli semishini kagesi ye-valve. . Ngalesi sikhathi, indlela yokulawula ukuhamba kwe-valve yesango kufanele ilungiswe engxenyeni evaliwe ngokugcwele. Ngalesi sikhathi, lapho uvula i-valve yesango, bala inani lokuphenduka kwe-stem rotation ye-valve yesango ukuze wazi ukuthi isendaweni "evulekile". Uma kuyi-valve yesango likagesi le-DN500, isikhala sezinyo le-stem singu-8mm, isiqu se-valve sizungeza kanye ukuze sivuleke u-8mm, futhi ipuleti levalvu yesango elivuleke ngokugcwele lidinga ukwenza umsebenzi wokuqina obheke phezulu ongu-500mm, ngakho isiqu se-valve esivuleke ngokugcwele sidinga ukuzungezisa. 500/8=62.5 amajika. Ngalesi sikhathi, cindezela ukhiye we-valve evulekile bese ubala ukuphenduka okungu-63 kwe-valve yesango endaweni “evulekile”, lungisa ibhodi yokulawula ukuhamba kwevalvu elawula ugesi, ukuze indawo yokushintsha yokuguqula endaweni “evulekile” ibe khona. Kusukela ngaleso sikhathi, i-valve yesango likagesi ingavalwa, ivuleke futhi ihlolwe futhi, futhi ukulungiswa kuqediwe. Uma i-valve yesango kagesi isendaweni yokuvula ngaphambi kokulungiswa, kufanele ilungiswe ukuze iqale isikhundla, inqubo ngokusho okungenhla.
3 Imibuzo evame ukubuzwa ngemva kokulungiswa
Unyaka owodwa ngemva kokusetshenziswa kwevalvu yesango likagesi, hlola ukuthi izikulufu zokulungisa ezikulungeni zokulungisa i-torque ziwile noma ziwile. Ikakhulukazi, uchungechunge lwe-ZD lwama-valve okulawula kagesi (njengoba kuboniswe kuMfanekiso 4), amanye ama-valve amasango kagesi avela ngesikhathi sokusebenzisa, isiphetho esiphansi se-valve yesango sigotshwe yipuleti le-valve noma ingxenye engaphezulu yedivayisi kagesi engaguquki. ipuleti lezimbambo elixhumayo liqhekekile. Kungani unomshini wokunciphisa i-torque, i-torque eningi uma ungekho esimweni sokuma, ungawuvali ukunikezwa kwamandla, isizathu siwukuthi isikulufu sokulungisa sesikulufu esilawulayo kumshini wokukhawulela itorque sikhululekile ukukhulula isikulufu esilawulayo isikhathi eside sokuqinisa isiphethu se-torsion, kuze kugaywe isiphethu se-torsion, ukuze indlela ekhawula itorque ilahlekelwe umphumela, ingabi umphumela we-buffer, okuholela engozini yokuphepha yokulimala kwevalvu yesango likagesi. Ngakho-ke, njalo ngonyaka ukuze uhlole ukuthi izikulufi ezilungisiwe ziyawa yini, uma izikulufo eziqinile zixega kufanele ziqiniswe, futhi uthole isizathu sokuwa kwesakhiwo esiqinisiwe.
Imanuwali - i-rocker yokushintsha kagesi ihlinzeka ngokuthi indlela yokusebenza kwemishini kulula, kulula ukuyijika, lapho ushintshela kumanuwali, ukuqinisekisa ukuthi ukunikezwa kwamandla, uma kwenzeka ingozi yokwehluleka.
Okwesikhathi eside abambalwa abavulekile, vala i-valve yesango ekushintsheni kwamandla avamile, ukuqinisekisa ukusebenza okuvamile okusetshenziswayo. (Kuphakanyiswa ukushintshanisa njalo ezinyangeni ezintathu).
