Izindlela zokuphepha eziyisithupha zokuthenga ama-valve

一. Ukusebenza kwamandla

Ukusebenza kwamandla kwe-valve kusho ikhono le-valve ukumelana nokucindezela kwe-medium. I-valve ingumkhiqizo wemishini othwala ingcindezi yangaphakathi, ngakho-ke kufanele ibe namandla anele kanye nokuqina ukuze kuqinisekiswe ukusetshenziswa kwesikhathi eside ngaphandle kokuqhekeka noma ukuguqulwa.

二. Ukusebenza kokuvala

Ukusebenza kokuvala kwe-valve kubhekisela ekhonweni lengxenye ngayinye evalayo ye-valve ukuvimbela ukuvuza kwendawo. Yinkomba ebaluleke kakhulu yokusebenza kwezobuchwepheshe ye-valve. Ivalvu inezingxenye ezintathu zokuvala: ukuxhumana phakathi kwezingxenye zokuvula nokuvala kanye nezindawo ezimbili zokuvala zesihlalo sevalvu; indawo ehambisanayo phakathi kokupakisha kanye nesiqu se-valve kanye nebhokisi lokugxusha; ukuxhumana phakathi komzimba we-valve nebhonethi. Ukuvuza kwangaphambili kubizwa ngokuthi ukuvuza kwangaphakathi, okuvame ukubizwa ngokuthi ukuvalwa kwe-lax, okuzothinta ikhono le-Taike valve ukusika okuphakathi. Kuma-valve okuvala, ukuvuza kwangaphakathi akuvunyelwe. Ukuvuza okubili kokugcina kubizwa ngokuthi ukuvuza kwangaphandle, okungukuthi, ukuvuza okuphakathi nendawo kusuka ngaphakathi kwevalvu kuya ngaphandle kwevalvu. Ukuvuza kungabangela ukulahlekelwa kwempahla, kungcolise imvelo, futhi kubangele izingozi ezimweni ezimbi kakhulu. Kwemidiya evuthayo, eqhumayo, enobuthi noma enemisebe, ukuvuza kwangaphandle akuvunyelwe, ngakho-ke amavalvu e-Taike kufanele abe nokusebenza okuthembekile kokuvala.

三, medium egelezayo

Ngemuva kokuthi i-medium igeleza nge-valve, ukulahlekelwa kwengcindezi (umehluko wengcindezi phakathi kwengaphambili nangemuva kwe-valve) kuzokwenzeka, okungukuthi, i-valve inokumelana okuthile nokugeleza kwe-medium, futhi i-medium isebenzisa inani elithile le-valve. amandla okunqoba ukumelana kwe-valve. Ngokombono wokulondoloza amandla, lapho uklama futhi ukhiqiza ama-valve, ukumelana kwe-valve endaweni egelezayo kufanele kuncishiswe ngangokunokwenzeka.

Amandla okuphakamisa kanye nomzuzu wokuphakamisa Amandla okuphakamisa kanye nomzuzu wokuphakamisa kubhekisela kumandla noma umzuzu okumelwe ufakwe kuvalvu ukuze uvule noma uvale. Lapho uvala i-valve, kuyadingeka ukwakha ingcindezi ethile yophawu oluthile phakathi kwezingxenye zokuvula nokuvala kanye nezindawo ezimbili zokuvala isihlalo, futhi ngesikhathi esifanayo unqobe igebe phakathi kwesiqu se-valve nokupakisha, intambo phakathi Isiqu se-valve namantongomane, kanye nesisekelo ekugcineni kwesiqu se-valve. Amandla okushayisana kwezinye izingxenye zokungqubuzana, ngakho-ke, amandla athile okuvala kanye ne-torque yokuvala kufanele kusetshenziswe. Phakathi nenqubo yokuvula nokuvala i-valve, amandla adingekayo okuvula nokuvala kanye ne-torque yokuvula nokuvala iyashintshwa, futhi inani eliphakeme likhona ngesikhathi sokugcina sokuvala noma ukuvula I-instantaneous yokuqala. Lapho uklama futhi ukhiqiza ama-valve, zama ukunciphisa amandla awo okuvala kanye ne-torque yokuvala.

四, isivinini sokuvula nokuvala

Isivinini sokuvula nokuvala sivezwa isikhathi esidingekayo ukuze i-valve iqedele isenzo sokuvula noma sokuvala. Ngokuvamile, azikho izidingo eziqinile ekuvuleni nasekuvaleni isivinini se-valve, kodwa ezinye izimo zokusebenza zinezidingo ezikhethekile zokuvula nokuvala isivinini. Uma ezinye zidinga ukuvuleka noma ukuvala ngokushesha ukuze kuvinjelwe izingozi, ezinye zidinga ukuvala kancane ukuze kuvinjelwe isando samanzi, njll. Lokhu kufanele kucatshangelwe lapho kukhethwa uhlobo lwevalvu.

五. Ukuzwela kwesenzo nokuthembeka

Lokhu kubhekisela ekuzweleni kwevalvu ukuphendula izinguquko kumapharamitha wemidiya. Kuma-valve anemisebenzi ethile efana nama-throttle valves, ama-valve okunciphisa ingcindezi, nama-valve alawulayo, kanye nama-valve anemisebenzi ethile efana nama-valve okuphepha nezicupho, ukuzwela kwawo okusebenzayo nokuthembeka kuyizinkomba ezibaluleke kakhulu zokusebenza kwezobuchwepheshe.

六, impilo yesevisi

Ikhombisa ukuqina kwevalvu, iyinkomba yokusebenza ebalulekile yevalvu, futhi inokubaluleka okukhulu kwezomnotho. Kuvame ukuvezwa ngokwenani lokuvuleka nokuvalwa okungaqinisekisa izidingo zokuvala, futhi kungavezwa nangesikhathi sokusetshenziswa.

Ngokwezinhlobo zamavalvu asetshenziswayo, imishini, insimbi, i-petrochemical, amakhemikhali, ukwakhiwa kwamadolobha kanye nezinye izimboni zinezinhlobo eziningi zamavalvu. Ikakhulukazi embonini yemishini, zonke izinhlobo zama-valve zisetshenziswa ngokuyisisekelo. Ngaphezu kwemboni yemishini, ama-valve emvemvane asetshenziswa ikakhulukazi ku-petrochemical and metallurgy; ama-valve e-diaphragm asetshenziswa kakhulu embonini ye-metallurgy, amandla kagesi kanye namakhemikhali; ama-valve okuhlola asetshenziswa kakhulu ku-metallurgy, embonini yamakhemikhali kanye ne-petrochemical; ama-valve okumisa asetshenziswa kakhulu embonini ye-petroleum namakhemikhali; ama-valve ebhola asetshenziswa kakhulu ku-petroleum, embonini yamakhemikhali kanye nokusansimbi; i-valve yokulawula isetshenziswa kakhulu embonini yamakhemikhali, i-metallurgy, amandla kagesi nokudla; I-valve yokunciphisa ingcindezi isetshenziswa ikakhulukazi ku-petrochemical, imboni yamakhemikhali kanye ne-metallurgy.
