Ingabe i-valve yokuhlola kufanele ifakwe ngaphambi nofana ngemva kwe-valve yokuphuma?

Eenhlelweni zamapayipi, ukukhethwa nokufakwa kwendawo yamavalvu kuqakathekile ekuqinisekiseni ukugeleza okulula kwamanzi nokuphepha kwehlelo. I-atikili le izakuhlola bonaamavalvu wokuhlolakufanele ifakwe ngaphambi nofana ngemva kwamavalvu wokuphuma, begodu ucoceamavalvu wesangokunyeIinhluzo zohlobo lwe-Y.

Kokuthoma, kufuze sizwisise umsebenzi weivalvu yokuhlola. Ivalvu yokuhlola yivalvu enendlela eyodwa esetjenziselwa ukukhandela ukugeleza emuva. Lokha uketshezi nalugeleza ngevalvu yokuhlola, idiski iyavuleka, ivumele uketshezi bona lugeleze. Lokha i-fluid nayigeleza ngendlela ehlukileko, idiski iyavala, ivimbele ukugeleza emuva. Uphawu lolu lwenza amavalvu wokuhlola abe mqoka eenhlelweni ezinengi zamapayipi, khulukhulu ukukhandela ukugeleza emuva emapompini nokuvikela imitjhini.

Nawucabanga bona ungafakaphiivalvu yokuhlola, ngokuvamileko kuneendlela ezimbili: ngaphambi nofana ngemva kwevalvu yokuphuma. Inzuzo ekulu yokufaka i-valve yokuhlola ngaphambi kwe-valve yokuphuma kukuthi ivimbela kuhle ukugeleza emuva, ivikela imitjhini esehla ekulimaleni. Ukuhleleka lokhu kuqakatheke khulu eenhlelweni ezitlhoga ukugeleza okuqondileko. Ukwenza isibonelo, ukufaka i-valve yokuhlola ekuphumeni kwepompo kuvimbela ukugeleza emuva ngemva kokuthi ipompo imisiwe, okungenzeka kulimaze ipompo.

Ngakelinye ihlangothi, ukufaka ivalvu yokuhlola ngemva kwevalvu yokuphuma nayo ineenzuzo zayo ezihlukileko. Kwezinye izehlakalo, ivalvu yokuphuma ingatlhoga ukulungiswa nofana ukutjhugululwa. Ukufaka ivalvu yokuhlola ngemva kwevalvu yokuphuma kwenza bona kube lula ukufikelela ngaphandle kokuphazamisa ukusebenza kwesistimu yoke. Ukudlula lapho, eenhlelweni zamapayipi eziyinkimbinkimbi, ukutjhugulula hlangana neendlela ezihlukahlukeneko zamanzi kungaba yinto etlhogekako. Ukufaka ivalvu yokuhlola ngemva kwevalvu yokuphuma kunikela ukutjhuguluka okukhulu.

Ngaphezu kwamavalvu wokuhlola,amavalvu wesangokunyeI-Y-strainersnazo zizinto ezijayelekileko eenhlelweni zamapayipi. Amavalvu wesango asetjenziselwa ukulawula ukugeleza kwe-fluid begodu avamise ukusetjenziswa eensetjenzisweni lapho indlela yokugeleza itlhoga ukuvulwa nofana ukuvalwa ngokupheleleko. Ngokungafani namavalvu wokuhlola, amavalvu wesango awavimbeli ukugeleza emuva. Ngalokho-ke, lokha nakuklanywa ihlelo lamapayipi, kuqakathekile ukuhlela kuhle imihlobo emibili yamavalvu ukuqinisekisa ukusebenza okuphephileko nokuphumelelako.

Iinsefo zohlobo lwe-Y zisetjenziselwa ukuhlunga ukusilaphazeka okuvela emanzini, ukuvikela ukusebenza okujayelekileko kwemitjhini ephasi. Lokha nawufakaIsihluzo sohlobo lwe-Y, ngokuvamileko kunconywa bona ifakwe ngaphambi kwe-valve yokuhlola ukuqinisekisa bona amanzi ahlungiweko angageleza kuhle angene emitjhini ephasi. Lokhu kuvimbela kuhle ukusilaphazeka bona kungalimazi imitjhini begodu kwenza ngcono ukuthembeka kwehlelo.

Ngokufingqa, indawo yokufaka i-valve yokuhlola kufanele inqunywe ngokuya ngeemfuneko ezithileko zesistimu yamapayipi. Nanyana ifakwe ngaphambi nofana ngemva kwevalvu yokuphuma, ubujamo be-fluid yesistimu, iimfuneko zokuvikelwa kwemitjhini, nobulula bokulondoloza kufanele kuqalwe ngokuzeleko. Ukudlula lapho, ukuhlelwa okufaneleko kwamavalvu wesango kanyeIinhluzo zohlobo lwe-Ykuzokwenza ngcono ukusebenza kuhle nokuphepha kwehlelo loke lamapayipi. Lokha nawuklama begodu ufaka ihlelo lamapayipi, kunconywa bona uthintane nomuntu oyingcweti ukuqinisekisa bona ivalvu ihlelwe kuhle.
