Ingabe kufanele kufakwe i-check valve ngaphambi noma ngemva kwe-outlet valve?

Ezinhlelweni zamapayipi, ukukhethwa kanye nendawo yokufaka ama-valve kubalulekile ekuqinisekiseni ukuhamba kahle koketshezi kanye nokuphepha kohlelo. Lesi sihloko sizohlola ukuthi ngabeama-valve okuhlolakufanele ifakwe ngaphambi noma ngemva kwama-valve okuphuma, bese nixoxaamavalvu esangofuthiIzihlungi zohlobo lwe-Y.

Okokuqala, sidinga ukuqonda umsebenzi we-ivalvu yokuhlola. I-valve yokuhlola iyi-valve enendlela eyodwa esetshenziswa kakhulu ukuvimbela ukugeleza emuva. Lapho uketshezi lugeleza nge-valve yokuhlola, i-disc iyavuleka, ivumela uketshezi ukuthi lugeleze. Lapho uketshezi lugeleza ngakolunye uhlangothi, i-disc iyavala, ivimbele ukugeleza emuva. Lesi sici senza ama-valve okuhlola abaluleke kakhulu ezinhlelweni eziningi zamapayipi, ikakhulukazi ekuvimbeleni ukugeleza emuva kwamaphampu kanye nemishini yokuvikela.

Uma ucabanga ukuthi uzoyifaka kuphi i-ivalvu yokuhlola, ngokuvamile kunezinketho ezimbili: ngaphambi noma ngemva kwevalvu yokuphuma. Inzuzo eyinhloko yokufaka ivalvu yokuhlola ngaphambi kwevalvu yokuphuma ukuthi ivimbela ngempumelelo ukugeleza emuva, ivikele imishini engezansi ekulimaleni. Lokhu kulungiselelwa kubaluleke kakhulu ezinhlelweni ezidinga ukugeleza okuqondile. Isibonelo, ukufaka ivalvu yokuhlola endaweni yokuphuma yephampu kuvimbela ukugeleza emuva ngemva kokuba iphampu imisiwe, okungalimaza iphampu.

Ngakolunye uhlangothi, ukufaka i-check valve ngemuva kwe-outlet valve nakho kunezinzuzo zako ezihlukile. Kwezinye izimo, i-outlet valve ingadinga ukulungiswa noma ukushintshwa. Ukufaka i-check valve ngemuva kwe-outlet valve kuvumela ukufinyelela okulula ngaphandle kokuphazamisa ukusebenza kwesistimu iyonke. Ngaphezu kwalokho, ezinhlelweni eziyinkimbinkimbi zamapayipi, ukushintsha phakathi kwezindlela ezahlukene zoketshezi kungadingeka. Ukufaka i-check valve ngemuva kwe-outlet valve kunikeza ukuguquguquka okukhulu.

Ngaphezu kokuhlola ama-valve,amavalvu esangofuthiIzihlungi ze-Yfuthi ziyizingxenye ezivamile ezinhlelweni zamapayipi. Amavalvu esango asetshenziswa kakhulu ukulawula ukugeleza koketshezi futhi avame ukusetshenziswa ezicelweni lapho indlela yokugeleza idinga ukuvulwa noma ukuvalwa ngokuphelele. Ngokungafani namavalvu okuhlola, amavalvu esango awavimbeli ukubuyela emuva. Ngakho-ke, lapho uklama uhlelo lwamapayipi, kubalulekile ukuhlela kahle lezi zinhlobo ezimbili zamavalvu ukuqinisekisa ukusebenza okuphephile nokusebenza kahle.

Izihlungi zohlobo lwe-Y zisetshenziselwa ukuhlunga ukungcola okuvela koketshezi, zivikela ukusebenza okuvamile kwemishini engezansi komfula. Uma ufaka i-Isihluzo sohlobo lwe-Y, ngokuvamile kunconywa ukuthi uyifake ngaphambi kwevalvu yokuhlola ukuqinisekisa ukuthi uketshezi oluhlungiwe lungageleza kahle emishinini engezansi komfula. Lokhu kuvimbela ngempumelelo ukungcola ekulimaleni imishini futhi kuthuthukisa ukuthembeka kohlelo.

Ngamafuphi, indawo yokufaka ivalvu yokuhlola kufanele inqunywe ngokusekelwe ezidingweni ezithile zesistimu yamapayipi. Kungakhathaliseki ukuthi ifakwe ngaphambi noma ngemva kwevalvu yokuphuma, izici zoketshezi zesistimu, izidingo zokuvikela imishini, kanye nokulula kokugcinwa kwayo kumele kucatshangelwe ngokuphelele. Ngaphezu kwalokho, ukuhlelwa okufanele kwamavalvu esango kanyeIzihlungi zohlobo lwe-Ykuzothuthukisa ukusebenza kahle kanye nokuphepha kohlelo lonke lwamapayipi. Lapho uklama futhi ufaka uhlelo lwamapayipi, kunconywa ukubonisana nochwepheshe ukuqinisekisa ukucushwa okuhle kakhulu kwevalvu.
