Yiziphi izindlela zokufaka ama-check valve？

Indlela yokufaka i-check valve inqunywa kakhulu ngohlobo lwe-check valve, izidingo ezithile zesistimu yamapayipi, kanye nendawo yokufaka. Nazi izindlela eziningana ezivamile zokufaka i-check valve:

Okokuqala, ukufakwa okuvundlile

1. Izidingo Ezijwayelekile: Ama-valve amaningi okuhlola, njengama-valve okuhlola okujikijelayo nama-valve okuhlola amapayipi, avame ukudinga ukufakwa okuvundlile. Uma ufaka, qiniseka ukuthi i-valve disc ingaphezu kwepayipi ukuze i-valve disc ivuleke kahle lapho uketshezi lugeleza phambili, futhi i-valve disc ingavalwa ngokushesha lapho ukugeleza kuguqulwa.

2. Izinyathelo zokufaka:

Ngaphambi kokufaka, hlola ukubukeka kanye nezingxenye zangaphakathi zevalvu yokuhlola ukuthi ziphelele futhi uqinisekise ukuthi idiski ingavulwa futhi ivalwe ngokukhululeka.

Hlanza ukungcola kanye nokungcola ngaphakathi nangaphandle kwepayipi ukuqinisekisa ukusebenza kokuvala kanye nokuphila kwesevisi yevalvu yokuhlola.

Beka i-valve yokuhlola endaweni yokufakwa enqunyiwe bese usebenzisa amathuluzi anjengesikrufu ukuze uyiqinise. Faka inani elifanele le-sealant endandatho yokuvala ukuqinisekisa ukusebenza kahle kokuvala.

Vula umthombo woketshezi bese uhlola isimo sokusebenza kwevalvu yokuhlola ukuqinisekisa ukuthi idiski ivuliwe futhi ivaliwe kahle.

Okwesibili, ukufakwa okuqondile

1. Uhlobo lokusetshenziswa: Amanye ama-check valve aklanywe ngokukhethekile, njengama-lift check valve, angadinga ukufakwa okuqondile. I-disc yalolu hlobo lwe-check valve ivame ukuhamba phezulu naphansi ku-axis, ngakho ukufakwa okuqondile kuqinisekisa ukunyakaza okubushelelezi kwe-disc.

2. Izinyathelo zokufaka:

Kuyadingeka futhi ukuhlola ukubukeka kanye nezingxenye zangaphakathi zevalvu yokuhlola ngaphambi kokufakwa.

Ngemva kokuhlanza ipayipi, beka ivalvu yokuhlola iqonde phezulu epayipini bese uyibopha ngethuluzi elifanele.

Qinisekisa ukuthi iziqondiso zokungena nokukhipha uketshezi zilungile ukuze ugweme ukucindezela okungadingekile noma ukulimala kwediski.

Okwesithathu, izindlela zokufaka ezikhethekile

1. I-valve yokuhlola i-clamp: Le valve yokuhlola ivame ukufakwa phakathi kwama-flange amabili, ifaneleka ngezikhathi ezidinga ukufakwa okusheshayo nokuhlukaniswa. Lapho uyifaka, kufanele kuqashelwe ukuthi indlela yokudlula kwe-clamp yokuhlola i-clamp ihambisana nendlela yokugeleza koketshezi, futhi kuqinisekiswe ukuthi ifakiwe ngokuqinile epayipini.

2. Ukufakwa kokushisela: Kwezinye izimo, njengezinhlelo zamapayipi okucindezela okuphezulu noma okushisa okuphezulu, kungadingeka ukushisela i-check valve epayipini. Lokhu kufakwa kudinga inqubo eqinile yokushisela kanye nokulawulwa kwekhwalithi ukuqinisekisa ukuqina nokuphepha kwe-check valve.

Okwesine, izinyathelo zokuphepha zokufaka

1. Isiqondiso: Uma ufaka i-check valve, qiniseka ukuthi indlela yokuvula i-valve disc ihambisana nendlela evamile yokugeleza koketshezi. Uma indlela yokufaka ingalungile, i-check valve ngeke isebenze kahle.

2. Ukuqina: Ukusebenza kokuvala kwevalvu yokuhlola kufanele kuqinisekiswe ngesikhathi sokufakwa. Kumavalvu okuhlola adinga i-sealant noma ama-gasket, wafake njengoba kunconywe umenzi.

3. Indawo yokulungisa: Uma ufaka i-check valve, izidingo zokulungisa nokulungisa zesikhathi esizayo kufanele zicatshangelwe. Shiya isikhala esanele se-return valve ukuze isuswe kalula futhi ishintshwe uma kudingeka.

Okwesihlanu, hlola bese uhlola ngemva kokufakwa

Ngemva kokufakwa, ama-check valve kufanele ahlolwe futhi ahlolwe ngokugcwele ukuqinisekisa ukuthi angasebenza kahle. Ungayisebenzisa ngesandla i-disc ye-check valve ukuze uhlole ukuthi ingavulwa futhi icinywe kalula. Ngesikhathi esifanayo, vula umthombo woketshezi, qaphela isimo sokusebenza se-check valve ngaphansi kokusebenza koketshezi, futhi uqinisekise ukuthi i-valve disc ingavulwa futhi ivalwe kahle.

Ngamafuphi, indlela yokufaka ivalvu yokuhlola kufanele inqunywe ngokwesimo esithile, okuhlanganisa uhlobo lwevalvu yokuhlola, izidingo zohlelo lwamapayipi, kanye nendawo yokufaka. Ngesikhathi senqubo yokufaka, izincomo zomenzi kanye nezincazelo zokufaka ezifanele kufanele zilandelwe ngokuqinile ukuqinisekisa ukusebenza okuvamile kanye nokusetshenziswa kwesikhathi eside kwevalvu yokuhlola.
