Isetshenziswa futhi igcinwe kanjani i-valve ngesikhathi sokusebenza, futhi yimiphi imithetho okufanele ukusebenza nokugcinwa kwe-valve kuhambisane nayo

Onjiniyela abaningi be-hydraulic banamakhono ekunakekeleni kwansuku zonke kwe-i-valve ohlelweni lokusebenza, futhi cishe awekho amaphutha, kodwa ngokuvamile azinaki izinkinga ezingenzeka ze-valve ohlelweni lokusebenza. Indlela yokusebenzisa nokugcina i-valve ohlelweni lokusebenza? Imiphi imithethonqubo okufanele ukusebenza nokugcinwa kwama-valve kuhambisane nayo? Njenge-valve ibaphendula ngamunye ngamunye!

1,Indlela yokusebenza nokugcina i-valve ngesikhathi sokusebenza

① Gcina izingxenye zangaphandle nezinyakazayo zevalvu zihlanzekile futhi uvikele ubuqotho bopende wevalvu. Intambo ye-trapezoidal, i-stem nut, izingxenye ezisekelayo ezishelelayo, igiya, izikelemu nezinye izingxenye endaweni ye-valve, isiqu ne-stem nut kulula ukufaka inani elikhulu lothuli, ibala likawoyela, izinsalela eziphakathi nendawo nokunye ukungcola, okubangela ukuguga nokugqwala i-valve.

Ngakho-ke, gcina i-valve ihlanzekile ngaso sonke isikhathi. Uthuli oluvamile ku-valve lufanele ukuhlanzwa kwebhulashi nokuhlanza umoya ocindezelwe, ngisho nangebhulashi lentambo yethusi kuze kube indawo emshinini ibonisa ukucwebezela kwensimbi, futhi indawo kapende ikhombisa umbala wangempela kapende.

I-steam trap izoba phezu komuntu onikezwe ngokukhethekile futhi ihlolwe okungenani kanye ngeshifu ngayinye; Vula i-valve yokudonsa kanye ne-steam trap njalo, noma uqaqa futhi ushaye njalo ukuze ugweme ukungcola okuvimbe i-valve.

② Gcina ukugcotshwa kwevalvu, intambo yesitebhisi se-valve, inadi ye-valve stem nezingxenye ezishelelayo ezisekelayo, indawo yokuthwala, igiya nezingxenye zokuxhuma izikelemu nezinye izingxenye ezinyakazayo. Izimo ezinhle zokugcoba ziyadingeka ukuze kuncishiswe ukungqubuzana futhi kugwenywe ukugqokisana. Ezingxenyeni ezingenayo inkomishi kawoyela noma umlomo wombhobho okulula ukonakala noma ukulahleka ngesikhathi sokusebenza, zonke izinhlelo zokuthambisa zizolungiswa ukuze kuqinisekiswe ukuncishiswa kwesekethe kawoyela.

Ingxenye yokugcoba kufanele igcwaliswe njalo ngokuya ngesimo esithile. Uma kuvame ukuvulwa, i-valve yokushisa ephezulu ifaneleka ukugcwalisa kanye ngesonto kuya enyangeni; Uma ingavulwa njalo, umjikelezo wokugcwalisa i-valve yezinga lokushisa eliphansi ungaba mude. Izinto zokugcoba zihlanganisa uwoyela, ibhotela, i-molybdenum disulfide negraphite. Amafutha enjini awafanele ama-valve okushisa aphezulu; Ibhotela nayo ayifaneleki. Izolahleka ngenxa yokuncibilika kumazinga okushisa aphezulu. I-valve yokushisa ephezulu ifaneleka ukwengeza i-molybdenum disulfide kanye nokusula i-graphite powder.

Uma izingxenye zokugcoba eziveziwe, njengezintambo ze-trapezoidal, phakathi kwamazinyo, njll, zisetshenziswa ngamafutha, kulula ukungcoliswa uthuli. Uma i-molybdenum disulfide ne-graphite powder zisetshenziselwa ukugcoba, akulula ukungcoliswa uthuli, futhi umphumela wokugcoba ungcono kunebhotela. I-graphite powder akulula ukuyisebenzisa ngokuqondile. Ingaxutshwa ibe inhlama ngamafutha amancane noma amanzi.

I-valve yepulaki izogcwaliswa ngamafutha ngesikhathi esibekiwe, ngaphandle kwalokho kulula ukugqoka nokuvuza.

③ Gcina zombili izingcezu ziqinile. Amabhawodi e-flange kanye nosekelo azolunga futhi ngeke akhululeke. Uma i-nati elibophayo esondweni lesandla lixega, lizoqiniswa ngesikhathi ukuze kugwenywe ukugqoka ilunga noma ukulahlekelwa yisondo lesandla.

Isondo lesandla ngeke lilahleke futhi lishintshwe ngesikhathi. Ukucindezela okuhlukile kokupakisha ngeke kuthambekele noma kungabi nokuvunyelwa kokulayisha kuqala. Endaweni engcoliswa kalula yimvula, iqhwa, uthuli, njll., induku ye-valve izofakwa isembozo sokuzivikela. Irula ku-valve kufanele iphelele futhi inembile. Isivalo sokuhola, ikhava kanye nezinsiza zomoya zevalvu zizobe zinjalo. Ijazi le-insulating ngeke libe nokucindezeleka nokuqhekeka.

Ukwengeza, akuvunyelwe ukungqongqoza i-valve, ukusekela izinto ezinzima noma izisebenzi zokumisa ukugwema ukungcolisa i-valve nokulimaza i-valve. Ikakhulukazi, i-mesh engeyona eyensimbi kanye nama-valve ensimbi ekhonjiwe avunyelwe.

Gcina ukunakekelwa kwansuku zonke kwempahla kagesi. Ukugcinwa kwezinto ezisebenza ngogesi ngokuvamile akubi ngaphansi kanye ngenyanga. Okuqukethwe kwesondlo kufaka: ukubukeka kuzohlanzeka ngaphandle kokunqwabelana kothuli, futhi okokusebenza akufanele kungcoliswe isitimu, amanzi namafutha; Indawo yokuvala kanye namaphoyinti kufanele aqine futhi aqine. Akukho ukuvuza;

Ingxenye yokugcoba izogcwaliswa ngamafutha ngokuvumelana nemithethonqubo, futhi i-valve nut izogcwaliswa ngamafutha; Ingxenye kagesi izoba iphelele ngaphandle kokuhluleka kwesigaba, ukushintshwa okuzenzakalelayo kanye ne-thermal relay akufanele kuboshwe, futhi ukukhanya kwenkomba kuzoboniswa ngendlela efanele.

2,Imiphi imithethonqubo okufanele ukusebenza nokugcinwa kwamavalvu kuhambisane nayo

Ukugcinwa nokuphathwa kwama-valve kuzohambisana nalokhu okulandelayo:

1. Ivalvu ye-solenoid eyisizayo yevalvu yehlathi lemvula izohlolwa nyanga zonke futhi izoba ngaphansi kokuhlolwa kokuqala. Uma isenzo singajwayelekile, sizoshintshwa ngesikhathi;

2. Ukunikezwa kwamandla nokusebenza kokuvula nokuvala kwevalvu kagesi kanye ne-solenoid valve kuzohlolwa njalo ngenyanga;

3. Wonke amavalvu okulawula ohlelweni kufanele amiswe endaweni evulekile noma eshiwo ngezigxivizo zomthofu noma amaketango. Izigxivizo zomthofu namaketango azohlolwa kanye ngenyanga. Uma kwenzeka umonakalo noma umonakalo, zizolungiswa futhi zishintshwe ngesikhathi;

4. Ivalvu yokulawula emthonjeni wangaphandle kanye nasepayipini elingenisa amanzi kufanele ihlolwe kanye ngekota, futhi kuzoqinisekiswa ukuthi ivuleke ngokugcwele;

5. Ukubukeka kwevalvu yokulawula umthombo wamanzi kanye neqembu le-alamu kufanele ihlolwe nsuku zonke, futhi uhlelo luyoba sesimweni sokungenaphutha;

6. Ukuhlolwa kokukhishwa kwamanzi kuzokwenziwa kuwo wonke amavalvu okuhlola amanzi okuphela kanye namavalvu okuhlola ukuchithwa kwamanzi evalvu ye-alamu yesistimu njalo ngekota, nokuthi ukuqalisa kwesistimu, ukusebenza kwe-alamu nesimo sokuphuma kwamanzi kujwayelekile yini kuzobhekwa;

7. Lapho i-valve yokuhlinzeka ngamanzi kamasipala ivuliwe ngokugcwele, ingcindezi ehlukile ye-backflow preventer izohlolwa njalo ngenyanga, futhi izohambisana nezinhlinzeko ezifanele zamazinga amanje kazwelonke: ingcindezi yokunciphisa i-backflow preventer GB / T 25178, ukugeleza okuphansi kokumelana isivimbeli i-JB / T 11151 nesivimbeli sokubuyela emuva kwe-valve yokuhlola kabili i-CJ/T 160.
