Indlela yokusebenza kunye nokugcina i-valve ngexesha lokusebenza, kwaye yeyiphi imimiselo ekufuneka ukusebenza kunye nokugcinwa kwevalve kuthotyelwe

Iinjineli ezininzi ze-hydraulic zinezakhono kugcino lwemihla ngemihla lweivalve kwinkqubo yokusebenza, kwaye akukho phantse iimpazamo, kodwa bahlala bengazinaki iingxaki ezinokwenzeka zevalve kwinkqubo yokusebenza. Indlela yokusebenza kunye nokugcina i-valve kwinkqubo yokusebenza? Yeyiphi imimiselo ekufuneka ukusebenza kunye nokugcinwa kweevalvu kuthotyelwe? Njengevalve ibaphendula nganye nganye!

1,Indlela yokusebenza kunye nokugcina i-valve ngexesha lokusebenza

① Gcina iindawo zangaphandle kunye nezihambayo zevalve zicocekile kwaye ukhusele ukunyaniseka kwepeyinti yevalve. Intambo ye-trapezoidal, i-stem nut, i-sliding parts, i-gear, i-worm kunye nezinye iindawo kumphezulu we-valve, i-stem kunye ne-stem nut kulula ukubeka uthuli oluninzi, i-oyile, intsalela ephakathi kunye nolunye ukungcola, okubangela ukuguga kunye nokugqwala. ivalve.

Ngoko ke, gcina ivalve icocekile ngamaxesha onke. Uthuli oluqhelekileyo kwivalve lufanelekile ukucoca ibrashi kunye nokucoca umoya ocinezelweyo, nokuba ngebrashi yocingo lobhedu de umphezulu owenziwe ngomatshini ubonise ukukhazimla kwesinyithi, kwaye umphezulu wepeyinti ubonisa umbala wokwenyani wepeyinti.

I-steam trap iya kuba phantsi kolawulo lomntu owabelwe ngokukodwa kwaye ihlolwe ubuncinane kanye ngeshifu; Vula ivalve yokugungxula kunye netrap yomphunga rhoqo, okanye uqhaqhe kwaye ugungxule rhoqo ukuthintela ubumdaka obuvalela ivalve.

② Gcina ivalve yokuthambisa, intambo yeleli yevalve, isiqu sevalve nut kunye nenkxaso yeendawo ezityibilikayo, indawo yokuthwala, igiya kunye neendawo zokumana iintshulube kunye nezinye iindawo ezihambayo ezihambelanayo. Iimeko ezilungileyo zokuthambisa ziyafuneka ukuze kuncitshiswe ukungqubana kunye nokuphepha ukunxiba. Kwiindawo ezingenayo i-oyile yekomityi okanye umbhobho ekulula ukonakala okanye ukulahleka ngexesha lokusebenza, zonke iinkqubo zokuthambisa ziya kulungiswa ukuze kuqinisekiswe ukuchithwa kwesekethe yeoli.

Inxalenye yokuthambisa iya kuzaliswa rhoqo ngokwemeko ethile. Ukuba isoloko ivulwa, i-valve ephezulu yokushisa ifanelekile ukunyusa i-refueling kanye ngeveki ukuya kwinyanga; Ukuba ayivulwa rhoqo, umjikelo we-refueling wevalve yobushushu obuphantsi unokuba mde. Izithambisi ziquka ioli, ibhotolo, imolybdenum disulfide kunye negraphite. I-oyile ye-injini ayifanelekanga kwi-valve ephezulu yokushisa; Ibhotolo ayifanelekanga nayo. Iya kulahleka ngenxa yokunyibilika kwiqondo lokushisa eliphezulu. Ivalve ephezulu yeqondo lokushisa ifanelekile ukongeza i-molybdenum disulfide kunye nokusula i-graphite powder.

Ukuba iindawo zokuthambisa eziveziweyo, ezinjengeentambo ze-trapezoidal, phakathi kwamazinyo, njl., zisetyenziselwa igrisi, kulula ukungcoliswa ngothuli. Ukuba i-molybdenum disulfide kunye ne-graphite powder zisetyenziselwa ukuthambisa, akulula ukungcoliswa ngothuli, kwaye umphumo wokugcoba ungcono kunebhotela. I-graphite powder ayilula ukuyisebenzisa ngokuthe ngqo. Inokuxutywa kwintlama ngeoli encinci okanye amanzi.

I-valve yeplagi iya kuzaliswa ngeoli ngexesha elichaziweyo, ngaphandle koko kulula ukugqoka kunye nokuvuza.

③ Gcina omabini amaqhekeza engaguquki. Iibholithi zeflange kunye nenkxaso ziya kuhlala zilungile kwaye aziyi kukhululeka. Ukuba i-nati yokuqinisa kwivili lesandla ikhululekile, iya kuqiniswa kwangethuba ukuphepha ukunxiba umdibaniso okanye ukulahlekelwa livili lesandla.

Ivili lesandla aliyi kulahleka kwaye litshintshwe ngexesha. Uxinzelelo lokwahluka kokupakisha aluyi kuthambekela okanye lungabikho ukukhutshwa kwangaphambili. Kwimekobume engcoliseke lula yimvula, ikhephu, uthuli, njl. njl., intonga yevalve iya kuxhotyiswa ngekhava yokukhusela. Irula ekwivalvu iya kuba epheleleyo kwaye ichaneke. Isitywina esikhokelayo, isigqubuthelo kunye nezixhobo zomoya zevalve ziya kuhlala zinjalo. Ijacket ye-insulating iya kukhululeka kuxinzelelo kunye nokuqhekeka.

Ukongezelela, akuvumelekanga ukunkqonkqoza i-valve, ukuxhasa izinto ezinzima okanye ukumisa abasebenzi ukuphepha ukuhlambalaza i-valve kunye nokonakalisa i-valve. Ngokukodwa, i-mesh engeyiyo i-mesh kunye ne-valve yentsimbi etyhidiweyo ayivumelekanga.

Gcina ulondolozo lwemihla ngemihla lwezixhobo zombane. Ukugcinwa kwezixhobo zombane ngokuqhelekileyo akukho ngaphantsi kanye ngenyanga. Iziqulatho zokugcinwa zibandakanya: ukubonakala kuya kucoceka ngaphandle kokuqokelelwa kothuli, kwaye izixhobo aziyi kungcoliswa ngumphunga, amanzi kunye neoli; Umphezulu wokutywina kunye namanqaku aya kuqina kwaye aqine. Akukho kuvuza;

Inxalenye yokuthambisa iya kuzaliswa ngeoli ngokwemimiselo, kwaye i-valve nut iya kuzaliswa ngamafutha; Inxalenye yombane iya kuhambelana ngaphandle kokungaphumeleli kwesigaba, ukutshintshela ngokuzenzekelayo kunye ne-thermal relay ayiyi kufakwa, kwaye ukukhanya kwesalathisi kuya kuboniswa ngokuchanekileyo.

2,Yeyiphi imimiselo ekufuneka ukusebenza kunye nokugcinwa kweevalvu kuthotyelwe

Ukugcinwa nokulawulwa kweevalvu kuya kuhambelana nale migaqo ilandelayo:

1. Ivalve ye-solenoid encedisayo yevalve yehlathi lemvula iya kuhlolwa rhoqo ngenyanga kwaye iya kuba phantsi kovavanyo lokuqalisa. Ukuba isenzo asiqhelekanga, siya kutshintshwa ngexesha;

2. Unikezelo lwamandla kunye nokusebenza kokuvula kunye nokuvala ivalve yombane kunye nevalve ye-solenoid kuya kuvavanywa rhoqo ngenyanga;

3. Zonke iivalve zokulawula kwisistim ziya kumiswa kwindawo evulekileyo okanye echaziweyo kunye nezitywina zokukhokela okanye amatyathanga. Izitywina ezikhokelayo kunye namatyathanga aya kuhlolwa kanye ngenyanga. Kwimeko yomonakalo okanye umonakalo, ziya kulungiswa kwaye zitshintshwe ngexesha;

4. Ivalve yokulawula kwivalve yangaphandle kunye nakumbhobho wokungena kwamanzi iya kuhlolwa kanye ngekota, kwaye iya kuqinisekiswa ukuba ivuleke ngokupheleleyo;

5. Inkangeleko yevalve yokulawula umthombo wamanzi kunye neqela levalvu ye-alam iya kuhlolwa yonke imihla, kwaye isixokelelwano siya kuba sikwimo engenaziphene;

6. Uvavanyo lokukhutshwa kwamanzi luya kuqhutywa kuzo zonke iivalvu zovavanyo lokuphela kwamanzi kunye neevalvu zovavanyo lokukhutshwa kwamanzi zevalve ye-alam yenkqubo rhoqo ngekota, kwaye ingaba inkqubo yokuqalisa, umsebenzi we-alam kunye nemeko yokuphuma kwamanzi iya kujongwa;

7. Xa ivalve yonikezelo lwamanzi kamasipala ivulwe ngokupheleleyo, uxinzelelo oluhlukileyo lokuthintela umva luya kuvavanywa nyanga zonke, kwaye luya kuhambelana nemimiselo echaphazelekayo yemigangatho yelizwe yangoku: uxinzelelo lokunciphisa ukubuyisela umva ukuvimbela i-GB / T 25178, ukuchasana okuphantsi kokubuyisela umva. Umthinteli we-JB / T 11151 kunye ne-valve ephindwe kabini yokukhusela i-backflow CJ / T 160.
