Ukusebenza kwe-valve yesondlo yansuku zonke

Ivalvu yokulungisa yansuku zonke ukusebenza okuyinhloko kobuchwepheshe Ukunakekela kwansuku zonke 1. Kufanele kuqashelwe indawo yokugcina ivalvu. Kufanele igcinwe ekamelweni elomile nelingena umoya futhi ivinjwe kuzo zombili iziphetho zesiteshi. 2, i-valve kufanele ihlolwe njalo, futhi isuse ukungcola kuyo, gcoba amafutha e-anti-rust ebusweni bayo. 3. Ngemuva kokufakwa nokusetshenziswa kwe-valve, kufanele ilungiswe njalo ukuze kuqinisekiswe umsebenzi wayo ovamile. 4. Hlola ukuthi indawo yokuvala yevalvu igugile futhi iyalungiswa noma uyishintshe ngokwesimo. 5, hlola ukugqokwa kwentambo ye-trapezoidal ye-stem kanye ne-stem nut, ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile, futhi wenze ukushintshwa okudingekayo. 6, ukusebenza kokuvalwa kwe-valve kufanele kuhlolwe ukuze kuqinisekiswe ukusebenza kwayo. 7. I-valve esebenzayo kufanele iphelele, ama-bolts ku-flange kanye nebakaki aphelele, izintambo azilinyazwa, futhi akukho mkhuba wokukhulula. I-8, uma isondo lesandla lilahlekile, kufanele lilungele ngesikhathi, futhi alikwazi ukushintshwa yi-wrench eguquguqukayo. 9. Ukupakisha indlala akuvunyelwe ukuba isontekile noma ngaphandle kwemvume yokulayisha kuqala. I-10, uma indawo yokusebenzisa i-valve iyimbi kakhulu, isengozini yemvula, iqhwa, uthuli, isihlabathi nokunye ukungcola, kufanele kufakwe isembozo sokuvikela isiqu. I-11, i-valve esikalini kufanele igcinwe iphelele, inembile, icacile, i-valve seal, i-cap. 12, ukwahlukanisa jacket akufanele sag, crack. I-13, ekusebenzeni kwe-valve, gwema ukuyingqongqoza, noma ukusekela izinto ezinzima, njll. Izinyathelo zokuhlanza Izingxenye ze-valve kufanele zidlule inqubo elandelayo ngaphambi kokuhlanganiswa: 1, ngokwezidingo zokucubungula, ezinye izingxenye zidinga ukwenza ukwelashwa kokupholisha, indawo engaphezulu ayikwazi ukuba ne-processing burr, njll.; 2. Zonke izingxenye zehlisiwe; 3, pickling passivation ngemva degreasing, yokuhlanza ejenti ayinayo phosphorus; I-4, i-pickling ehlanjululwe ngamanzi ahlanzekile ngemva kokugeza, ayikwazi ukuba nensalela yezidakamizwa, izingxenye ze-carbon steel zishiya lesi sinyathelo; 5, ingxenye ngayinye ngendwangu engeyona eyelukiweyo eyomile, ayikwazi ukugcina izingxenye zoboya zocingo, noma nge-nitrogen ehlanzekile eyomile; 6. Sula izingxenye ngayinye ngayinye ngendwangu engalukiwe noma iphepha lokuhlunga elinemba elinotshwala obumsulwa kuze kungabi bikho umbala ongcolile. Ukusebenza okuyinhloko kobuchwepheshe kwezingxenye zokuvala i-valve ye-valve yekhono lokuvimbela ukuvuza kwemidiya, kuyizinkomba ezibaluleke kakhulu zokusebenza kwezobuchwepheshe ze-valve. Kunezingxenye ezintathu zokuvala zevalvu: ukuthintana phakathi kwezingxenye zokuvula nokuvala kanye nesihlalo sevalvu izingxenye ezimbili zokuvala; Ukupakisha kanye nesiqu se-valve nokuhambisana nebhokisi lokupakisha; Ukuhlangana komzimba kubhonethi. Okunye ukuvuza kwangaphambili kubizwa ngokuthi ukuvuza kwangaphakathi, okuvame ukubizwa ngokuthi ukuxega, kuzophazamisa ikhono le-valve ukusika i-medium. Ukusebenza okuyinhloko kobuchwepheshe kwe-valve Okokuqala, ukusebenza kokuvalwa kwe-valve Kubhekisela ezingxenyeni zokuvala i-valve zekhono lokuvimbela ukuvuza kwemidiya, kuyizinkomba zokusebenza kwezobuchwepheshe ezibaluleke kakhulu zevalvu. Kunezingxenye ezintathu zokuvala zevalvu: ukuthintana phakathi kwezingxenye zokuvula nokuvala kanye nesihlalo sevalvu izindawo ezimbili zokuvala; Ukupakisha kanye nesiqu se-valve nokuhambisana nebhokisi lokupakisha; Ukuhlangana komzimba kubhonethi. Okunye ukuvuza kwangaphambili kubizwa ngokuthi ukuvuza kwangaphakathi, okuvame ukubizwa ngokuthi ukuxega, kuzophazamisa ikhono le-valve ukusika i-medium. Esigabeni se-valve ye-block, ukuvuza kwangaphakathi akuvunyelwe. Ukuvuza okubili kokugcina kubizwa ngokuthi ukuvuza kwangaphandle, okungukuthi, ukuvuza kwemidiya kusuka kuvalvu kuya kuvalvu ngaphandle. Ukuvuza kuzodala ukulahleka kwempahla, ukungcoliswa kwemvelo, okungathí sina nakho kuzodala izingozi. Ngemidiya evuthayo, eqhumayo, enobuthi noma enemisebe, ukuvuza akuvunyelwe, ngakho-ke i-valve kufanele ibe nokusebenza okuthembekile kokuvala. Okwesibili, i-flow medium I-flow medium ibhekisela ku-medium ngokusebenzisa i-valve izokhiqiza ukulahlekelwa kwengcindezi (umehluko wengcindezi ngaphambi nangemva kwe-valve), okungukuthi, i-valve inokumelana okuthile nokugeleza kwe-medium, medium ukunqoba ukumelana. ye-valve izodla inani elithile lamandla. Kusukela ekucabangeni ukonga amandla, ukuklama kanye nokukhiqizwa kwama-valve ukunciphisa ukumelana ne-valve ku-flow medium ngangokunokwenzeka. Okwesithathu, amandla okuvula nokuvala kanye nomzuzu wokuvula nokuvala Amandla okuvula nokuvala kanye ne-torque amandla noma ama-torque okufanele asetshenziswe ukuvula noma ukuvala i-valve. Vala i-valve, isidingo sokwenza ingxenye evulekile-vala futhi uthumele ifomu uphawu phakathi kokucindezela okubili kokuvala kwendawo, kodwa futhi unqobe phakathi kwesiqu nokupakisha, isiqu se-valve naphakathi kwemicu yentongomane, i-valve rod end bearing friction and ezinye izingxenye zamandla okushayisana, ngakho-ke kufanele zisebenzise amandla okuvala kanye nomzuzu oseduze, ngesikhathi sokuvula nokuvala, i-valve iyadingeka ukuze uvule futhi uvale amandla kanye nezinguquko ze-torque evulekile, Inani layo eliphezulu lisekupheleni umzuzu ovaliwe noma ekuqaleni komzuzu ovulekile. Ama-valve kufanele aklanywe futhi enziwe ukuze kuncishiswe amandla okuvala kanye ne-torque yokuvala. Okwesine, isivinini sokuvula nokuvala Isivinini sokuvula nokuvala sivezwa njengesikhathi esidingekayo ukuqedela isenzo sokuvula noma sokuvala i-valve. Isivinini esivamile sokuvula nokuvala akuzona izidingo eziqinile, kodwa ezinye izimo zinezidingo ezikhethekile zokuvula nokuvala isivinini, njengezinye izidingo zokuvula noma ukuvala ngokushesha, uma kwenzeka izingozi, ezinye izidingo zokuvala kancane, uma kwenzeka isiteleka samanzi, okufanele kucatshangelwe lapho kukhethwa uhlobo lwe-valve. Okwesihlanu, ukuzwela kokunyakaza kanye nokwethembeka Ukuzwela kwesenzo nokuthembeka kubhekisela kuvalvu yezinguquko zepharamitha ephakathi, yenza impendulo ehambisanayo nezinga lokuzwela. I-valve ye-throttle, i-valve yokunciphisa ingcindezi, i-valve elawulayo namanye ama-valve asetshenziselwa ukulungisa imingcele ye-medium kanye ne-valve yokuphepha, i-valve yesicupho kanye namanye ama-valve anemisebenzi ethile, ukuzwela kwayo okusebenzayo nokuthembeka kuyizinkomba zokusebenza kwezobuchwepheshe ezibaluleke kakhulu. Isithupha, impilo yesevisi Impilo yesevisi isho ukuqina kwevalvu, iyinkomba ebalulekile yokusebenza kwevalvu, futhi inokubaluleka okukhulu kwezomnotho. Ngokuvamile ukuze kuqinisekiswe izidingo zokubekwa uphawu kwenani lezikhathi zokuveza, kungabuye kuboniswe ngokusetshenziswa kwesikhathi.
