Umlawuli wokunciphisa uxinzelelo yivalvu enciphisa uxinzelelo lokungena ukuya kuxinzelelo oluthile olufunekayo lokukhupha ngokulungelelanisa, kwaye ixhomekeke kumandla esixhobo ngokwaso ukugcina uxinzelelo lokukhupha luzinzile ngokuzenzekelayo.
Ukutshintshatshintsha koxinzelelo lokungena lwevalvu yokunciphisa uxinzelelo kufuneka kulawulwe ngaphakathi kwe-80% - 105% yexabiso elinikiweyo loxinzelelo lokungena. Ukuba ludlula olu luhlu, ukusebenza kweivalvu yokunciphisa uxinzeleloiza kuchaphazeleka.
1. Ngokubanzi, uxinzelelo olusezantsi emva kokunciphisa akufanele lube ngaphezu kwezihlandlo eziyi-0.5 zoxinzelelo oluphezulu
2. Intwasahlobo yegiya nganye yevalvu yokunciphisa uxinzelelo isebenza kuphela kuluhlu oluthile loxinzelelo lwe-outlet, kwaye intwasahlobo kufuneka itshintshwe ukuba ingaphaya koluhlu.
3. Xa ubushushu bemidiya buphezulu, kufuneka kukhethwe ivalvu yokunceda umqhubi wenqwelomoya okanye ivalvu etywiniweyo yenqwelomoya yenqwelomoya ngokubanzi.
4. Xa i-medium ingumoya okanye amanzi, kufuneka kukhethwe i-diaphragm valve okanye i-pilot relief valve.
5. Xa i-medium ingumphunga, kufuneka kukhethwe ivalvu yokunceda umqhubi okanye ivalvu etywiniweyo.
6. Ivalvu yokunciphisa uxinzelelo kufuneka ifakwe kwiipayipi ezithe tye ukuze kube lula ngakumbi ukusebenza, ukulungiswa kunye nokugcinwa kwayo.
Ngokweemfuno zokusetyenziswa, uhlobo kunye nokuchaneka kwevalvu elawula uxinzelelo kuyakhethwa, kwaye ububanzi bevalvu bukhethwa ngokwendlela ephezulu yokuphuma. Xa kumiselwa uxinzelelo lomoya lwevalvu, kufuneka lube ngaphezu koxinzelelo oluphezulu lokuphuma lwe-0.1MPa. Ivalvu yokunciphisa uxinzelelo ngokubanzi ifakwa emva kwesahluli samanzi, ngaphambi kwe-oyile okanye isixhobo sokuseta, kwaye qaphela ukuba ungayiqhagamsheli i-inlet kunye ne-outlet yevalvu ngokubuyela umva; xa ivalvu ingasetyenziswa, iqhina kufuneka likhululwe ukuze kuthintelwe ukuba i-diaphragm isoloko iphantsi kotshintsho loxinzelelo kwaye ichaphazele ukusebenza kwayo.
