Yini umehluko emkhatsini we-valve ye-globe ne-valve yesango?

I-valve ye-globe kanye ne-valve yesango kunekufana lokutsite ngekubukeka, futsi bobabili banemsebenti wekusika emaphayiphini, ngako bantfu bavame kutibuta, yini umehluko emkhatsini we-valve ye-globe ne-valve yesango?

Ivalvu yemhlaba, ivalvu yesango,ivalvu yevivane, hlola valve kanye nebhola valve tonkhe tincenye tekulawula letidzingekako etinhlelo letehlukene temaphayiphi. Luhlobo ngalunye lwevalve luhlukile ngekubukeka, sakhiwo ngisho nekusetjentiswa lokusebenta. Kepha i-valve yemhlaba kanye ne-valve yesango inekufana lokutsite ngesimo, futsi ngesikhatsi lesifanako inemsebenti wekusika emgceni, ngako-ke kutawuba nebangani labanyenti labangenakutsintsana kakhulu nevalve kutawudida laba lababili. Ecinisweni, uma ubukisisa, umehluko emkhatsini wevalve yemhlaba kanye nevalve yesango mkhulu impela. Lesihloko sitawetfula umehluko emkhatsini we-valve ye-globe kanye ne-valve yesango.

1. Umtsetfo lohlukile wekusebenta emkhatsini wevalve yemhlaba kanye nevalve yesango
Uma ivalve ye globe ivulwa futsi ivalwe, ijika esondvweni lesandla, lelisondvo lesandla litawujika futsi liphakamise kanye nesicu se valve, kantsi le valve yesango itawujika lisondvo lesandla kuphakamisa lever ye valve, futsi indzawo yelisondvo lesandla ngokwayo ihlala ingashintjwa.

IIvalvu yesango lehleti ngerabhainetifundza letimbili kuphela: kuvulwa lokugcwele noma kuvalwa lokugcwele ngesikhatsi lesidze sekuvulwa nekuvalwa; le stroke yekuhamba kwe globe valve incane kakhulu, futsi ipuleti le valve ingapakwa endzaweni letsite ngekunyakata kwentela kulawula kugeleza, kantsi le valve yesango ingajutjwa kuphela ngaphandle kweminye imisebenti.

2. Umehluko wekusebenta emkhatsini wevalvu yemhlaba kanye nevalvu yesango
I valve ye globe inganqunywa bese isetjentiselwa umtsetfo wekugeleza. Kumelana kwemanti kwe globe valve kukhulu kakhulu, futsi kumatima kuvula nekuvala, kepha ngoba ipuleti le valve imfishane kusuka endzaweni yekuvala, ngako-ke kuvula nekuvala stroke imfishane.

I-valve yesango le-BS5163 ingavulwa ngalokuphelele futsi ivalwe kuphela. Uma sekuvulwe ngalokuphelele, kumela kwekugeleza kwemkhakha emseleni wemtimba wevalve kucishe kube ngu 0, ngako-ke kuvulwa nekuvalwa kwevalve yesango kutawuba lula kakhulu, kepha lisango likhashane nendzawo yekuvala, futsi sikhatsi sekuvulwa nekuvalwa sidze.

3. Kufakwa umehluko wesicondziso sekugeleta kwevalve yemhlaba kanye nevalve yesango
Resilient gate valve kugeleza kuto totimbili ticondziso babe umphumela lofanako, kufakwa kute tidzingo tekungenisa kanye nekutfumela sicondziso, lesemkhatsini ingageleta kuto totimbili ticondziso.

I-valve ye-globe idinga kufakwa ngekuhambisana ngalokucinile nesicondziso semcibisholo wemtimba we-valve. Kukhona umtsetfo locacile mayelana nendlela yekungena nekuphuma kwe valve ye globe, futsi le valve “letintsatfu kuya” ibeka kutsi indlela yekugeleta ye valve yekumisa isetjentiswa kusuka etulu kuya phansi.

4. Umehluko wesakhiwo emkhatsini wevalvu yemhlaba kanye nevalvu yesango
Isakhiwo sevalve yesango sitawuba yinkimbinkimbi kakhulu kunevalve yemhlaba. Kusuka ekubukekeni kwe diameter lefanako, le valve yesango kumele ibe ngetulu kwe valve ye globe, bese le valve ye globe kumele ibe yindze kune valve ye sango. Ngetulu kwaloko, ivalve yesango ine .Sicu LesikhuphukakofutsiSicu lesingakhuphuki, ivalve yemhlaba ayikwenti loko.
