1. Ngokusho kokukhethwa kwemisebenzi yokulawula, ama-valve ahlukahlukene anemisebenzi yawo, futhi kufanele kuqashelwe imisebenzi ehambisanayo lapho kukhethwa.

2. Ngokusho kokukhethwa kwezimo zokusebenza, imingcele yezobuchwepheshe evame ukusetshenziswaI-Valve Yebhola Yethusizihlanganisa ingcindezi yesikali sokusebenza, ingcindezi yokusebenza ephezulu evumelekile, izinga lokushisa lokusebenza (izinga lokushisa elincane neliphezulu kakhulu) kanye neliphakathi (ukugqwala, ukuvutha).Lapho ukhetha, qaphela imingcele eshiwo ngenhla yezimo zokusebenza kanye nemingcele yezobuchwepheshe ye-valve iyahambisana.

3. Khetha ngokuvumelana nesakhiwo sokufaka.Isakhiwo sokufakwa kwesistimu yamapayipi sihlanganisa intambo yamapayipi, i-flange, i-ferrule, i-welding, i-hose nokunye.Ngakho-ke, isakhiwo sokufakwa kwe-valve kufanele sihambisane nesakhiwo sokufakwa kwepayipi, futhi ukucaciswa nobukhulu kufanele kuhambisane.

Ukufakwa kwe-valve yethusi

1. I-valve exhunywe ngentambo yepayipi ixhunywe nentambo yepayipi yokuphela kwepayipi.Intambo yangaphakathi ingaba intambo yepayipi ye-cylindrical noma intambo yepayipi ene-tapered, futhi intambo yangaphandle kufanele ibe intambo yepayipi eqoshiwe.

2. I-valve yesango enokuxhumeka kwentambo yangaphakathi ixhunywe ekugcineni kwepayipi, futhi ubude bentambo yangaphandle yokuphela kwepayipi idinga ukulawulwa.Ukuze uvimbele ukuthi ukuphela kwepayipi kungafinyezwa kakhulu ukuze ucindezele ingxenye yangaphakathi yokugcina yentambo yepayipi levalvu yesango, isihlalo sevalvu sizokonakala futhi ukusebenza kokuvala kuzophazamiseka.

3. Ama-valve axhunywe ngentambo yepayipi, lapho ufaka futhi uqiniswa, i-wrench kufanele ikhishwe engxenyeni ene-hexagonal noma i-octagonal ekugcineni kwentambo, futhi akufanele ihlulwe engxenyeni ene-hexagonal noma i-octagonal ngakolunye uhlangothi lwe-valve. ukugwema ukuguqulwa kwe-valve.

4. I-Flange exhuma i-flange ye-valve kanye ne-flange yokuphela kwepayipi ayihambisani nje nokucaciswa nobukhulu, kodwa futhi nokucindezela okufanayo okubizwa ngokuthi.

5. Uma isiqu se-valve sitholakala sivuza ngesikhathi sokufakwa kanye nokusetshenziswa kwe-valve yokumisa kanye ne-valve yesango, qinisa nati lokucindezela lapho upakisha, futhi unake amandla amaningi, inqobo nje uma kungekho ukuvuza.
