Ukwehluleka komthetho kagesi

Ingcindezi yokulawula ukwehluleka kwenzeka ngokusetshenziswa kwe-valve echichimayo. Kunethuba ezimbili zokutholwa komthethonqubo ukwehluleka kwe-Pilot Sukuma Valve Valve: eyodwa ukuthi ingcindezi ayikwazi ukusungulwa ngokulungisa ingcindezi elawula i-handwheel, noma ingcindezi ayikwazi ukufinyelela inani elilinganiselwe; Enye indlela ukulungisa ingcindezi yesandla ngaphandle kokuwa, noma ukwandisa ingcindezi ngokuqhubekayo. Kunezizathu ezithile zokwehluleka kokulawulwa kwengcindezi, ngaphandle kokuqubuka kwe-radial of the valve core ngenxa yezizathu ezahlukahlukene:

Okokuqala, ingozi yengozi yomzimba oyinhloko (2) ivinjiwe, futhi ingcindezi kawoyela ayikwazi ukudluliselwa egumbini eliphezulu le-valve eliyinhloko negumbi langaphambili le-pleot valve, ukuze i-pleve valve ilahlekelwe yingcindezi ye-valve enkulu. Ngoba akukho ukucindezela kawoyela egumbini eliphezulu le-valve enkulu kanye namandla entwasahlobo kuncane kakhulu, i-valve eyinhloko iba yi-valve yokusiza eqondile enamandla amakhulu entwasahlobo. Lapho ingcindezi egumbini lokungena uwoyela liphansi kakhulu, i-valve eyinhloko ivula i-valve yokusiza futhi uhlelo lungakwazi ukukhokhela ingcindezi.

Isizathu esenza ukuthi ingcindezi ingakwazi ukufinyelela inani elilinganiselwe ukuthi intwasahlobo yokuqothula ingcindezi idonswa noma ikhethwe ngokungafanele, ukuvuza kwengcindezi kwe-valve kukhulu kakhulu, noma i-valve ye-valve ye-Pilot igqoke ngokweqile.

Okwesibili, imbila (3) ivinjiwe, ukuze ukucindezelwa kawoyela kungadluli ku-cane valve, futhi i-valve yokushayela ilahlekelwa umsebenzi wokuguqula ingcindezi ye-valve enkulu. Ngemuva kokuthi i-camper (orifice) ivinjiwe, i-valve valve ngeke ivule i-oyela echichimayo ngaphansi kwanoma iyiphi ingcindezi, futhi akukho mafutha ageleze e-valve ngaso sonke isikhathi. Ingcindezi emakamelweni aphezulu nangaphansi we-valve eyinhloko ihlala ilingana. Ngoba indawo ethwala yonyaka yonyaka ekugcineni kwe-main valve core inkulu kakhulu kunaleyo emaphethelweni aphansi, i-valve eyinhloko ihlala ivalwa futhi ngeke ichichime, futhi ingcindezi ye-valve enkulu izokwanda ngokukhula komthwalo. Lapho i-actuator iyeka ukusebenza, ingcindezi yohlelo izokhula unomphela. Ngaphezu kwalezi zizathu, kusadingekile ukubheka ukuthi ichweba lokulawula langaphandle livinjiwe nokuthi ngabe i-valve ye-cone ifakwe kahle.
