Yini amaphuzu asemqoka ekukhetheni ama-valve ama-Check

Ukukhethwa kweBheka ama-valvesIdinga ukucubungula okuphelele kwezinto eziningi ukuqinisekisa ukusebenza okuzinzile nokuthembekile ngaphansi kwezimo ezithile zokusebenza, kanye nokuvimbela okusebenzayo kokubuyela emuva okuphakathi. Okulandelayo amaphuzu okukhetha asemqoka:

Ngokwezici eziphakathi, uhlobo oluphakathi kufanele luchazwe ngokucacile, futhi uhlole ama-valves alungele izici zokuhamba kwegesi kufanele akhethwe amapayipi kaphethiloli, njengama-rotary valves; Imidiya ewuketshezi ingakhethwa njengokuphakamisa uhlobo ngaphansi kwezimo ezifanele zokusebenza; Uhlelo lwe-Steam kufanele lubheke ukubekezelela kwalo ku-High Credite Steam kanye nokukhishwa kwe-condensate, kanye nohlobo lwedayaphragm kwesinye isikhathi kufanelekile. Uma i-Medium iyonakaliswa, njenge-acid noma i-alkali solutions, hlola ama-valve enziwe ngezinto zokulwa nokugqwala kufanele zikhethwe. Ama-valve disc for a acid media ane-acid angenziwa nge-polytetrafluoroethylene, kanye nensimbi engenacala kufanele akhethwe ngosawoti oqukethe imidiya equkethe imidiya enjenge-olwandle. Isimo esiphakeme esiphakeme sithinta ukuguquguquka kokuvulwa kwe-valve nokuvala. Okwe-Liquid anokuvunywa okuphezulu, gwema ukukhetha uhlobo lokuphakamisa ngokumelana okuphezulu, bese ubheka uhlobo lokujikeleza noma uvemvane. Kwabezindaba eziqukethe izinhlayiya eziqinile, hlola ama-valves anokumelana okuhle kufanele akhethwe. Ama-valve disc kanye nezihlalo zamapayipi afana nokudonsa okwami kungakhiwa ama-halloy anzima, noma ama-valve akhethekile aklanyelwe kufanele akhethwe.

Ngokuya ngemingcele yokusebenza, khetha aBheka i-valvengengcindezi efanelekile (PN) esuselwa ekucindezelweni okusebenzayo kohlelo lwepayipi. Ingcindezi ephakeme kufanele ibe nkulu kunengcindezi yokusebenza ephezulu futhi ishiye imajini yokuphepha. Uma ucabanga ngokushisa kwangempela kokusebenza kwe-medium, qiniseka ukuthi i-valve ye-Checkve ihlanganisa uhla lokushisa olusebenzayo, futhi izinto ezahlukene zinamazinga okushisa ahlukile asebenzayo. Khetha i-valve yesheke enesilinganiso esifanelekile (i-DN) esuselwa ekuhambeni kwezinga lokugeleza kohlelo lwepayipi, okufanele lihambisane nobubanzi bepayipi. Usayizi ungakhethwa ngokubhekisa ku-Flow Resransance Isici Sokuvimba.

Ezimfuneko zokufaka, izinhlobo ezahlukene zama-valves ezihlolo zinezidingo ezihlukile zezikhundla zokufaka. Uhlobo lokuphakamisa luvame ukufakwa kumapayipi avundlile, uhlobo lwe-swing alunqunyelwe, futhi uhlobo lwevemvane lufakwe kumapayipi mpo. Ukugeleza kokugeleza okuphakathi kufanele kube kusuka phansi kuya phezulu. Inkomba yokufaka kumele ihambisane nesiqondisi somcibisholo womzimba we-valve. Ukukhethwa kufanele kubheke isikhala sendawo yokufaka bese ukhetha i-valve yesheke ngesakhiwo esihlangene nosayizi ofanele.

Ngokuya kwezidingo zomsebenzi, ama-valves okuhlola kufanele akhethwe ngokwezidingo zokubekwa uphawu kohlelo. Ngezinhlelo ezinezidingo ezijulile zokuvuza, ama-valve athambile wesakhiwo sezinkwa zokwesabisa ngokusebenza kahle kokusebenza uphawu kufanele akhethwe. Ngezinhlelo ezizwelayo ekushintsheni kwengcindezi, khetha uhlolo ama-valve anokuvulwa okuncane nokuvalwa kwengcindezelo. Izinhlelo ezinde zokuqhubeka nokusebenza kufanele zibheke impilo yenkonzo yeBheka ama-valvesbese ukhetha izinto ezithembekile neziphezulu.
