4.Ithiyori yomsebenzi

I-valve yokuhlola ivula ngokuzenzekelayo bese ivala i-disc ukuvimbela ukugeleza okuphakathi kuya emuva ngokugeleza okuphakathi.

5. Izindinganiso ze-valve ezisebenzayo kepha azikhawulelwe ku:

（1, API 6D-2002, 2, ASME B16.5-2003

（3, ASME B16.10-2000, 4, i-API 598-2004

） 5） GB / T 12235-1989 （6） GB / T 12236-1989

6. Isitoreji Nokunakekela & Ukufaka & Ukusebenza

I-6.1 I-valve kufanele igcinwe ekamelweni elomile nelinomoya omuhle. Imikhawulo yokuhamba kufanele ixhunywe ngezembozo.

6.2 Amaphayiphu angaphansi kwesitoreji sesikhathi eside kufanele ahlolwe futhi ahlanzwe njalo, ikakhulukazi ubuso bokuhlala ukuvimbela ukulimala kwawo, futhi ubuso bokuhlala kufanele bufakwe ukugqwala okuvimbela uwoyela

Ukumaka kwe-Valve kufanele kuhlolwe ukuhambisana nokusetshenziswa.

I-6.4 Valve cavity kanye nendawo yokubekwa uphawu kufanele ihlolwe ngaphambi kokufakwa futhi isuse ukungcola uma kukhona.

Isiqondiso se-Arrow kufanele silingane nesiqondiso sokugeleza.

6.6 Ukuphakamisa i-valve yokuhlola yediski emile kufanele kufakwe kuqonde kupayipi. Ukuphakamisa i-valve yokuhlola yediski evundlile kufanele ifakwe ngokuvundlile kupayipi.

6.7 Ukudlidlizela kufanele kuhlolwe futhi kufanele kushintshwe ukushintshwa kwengcindezi ephakathi kwamapayipi ukuvimbela umphumela wamanzi.

Izinkinga ezingaba khona, izimbangela kanye nesilinganiso sokulungisa

Izinkinga Ezingaba khona	Izimbangela	Isilinganiso sokulungisa
Idiski ayikwazi ukuvula noma ukuvala	Ingalo ye-Rocker ne-pin shaft icinene kakhulu noma okuthile kuvimba Ukungcola kuvimba ngaphakathi kwe-valve Bheka isimo sokufana Susa ukungcola
Ukuvuza	IBolt ayiqinile ngisho Flange seal ebusweni umonakalo Ukulimala kwe-gasket Qiniseka ngokulinganayo Lungisa Shintsha i-gasket entsha
Umsindo nokudlidliza	Valve eseduze kakhulu futha Ingcindezi emaphakathi ayizinzile Hambisa ama-valve Susa ukuguquguquka kwengcindezi

8. Iwaranti

Ngemuva kokuthi i-valve isetshenzisiwe, isikhathi sewaranti izinyanga eziyi-12, kepha asidluli izinyanga eziyi-18 ngemuva kosuku lokulethwa. Ngesikhathi sewaranti, umenzi uzohlinzeka ngensizakalo yokulungisa noma izingxenye ezisele mahhala ngomonakalo ngenxa yezinto ezibonakalayo, ubungcweti noma ukulimala uma umsebenzi usebenza kahle.
