Ukusebenza ngokuchanekileyo kwevalve yokhuseleko
I-valve yokhuseleko iye yafumana uvavanyo loxinzelelo kunye noxinzelelo oluqhubekayo ngaphambi kokufakwa. Xa ivalve yokhuseleko isebenza ixesha elide, umqhubi uya kunika ingqalelo ekuhlolweni kwevalve yokhuseleko. Ngexesha lokuhlolwa, umqhubi uya kunqanda ukuphuma kwevalve yokhuseleko, ajonge isitywina esikhokelayo sevalve yokhuseleko, akhuphe ivalve yokhuseleko ngesikroba ngesandla, kwaye ayivule kanye ngexesha lokukhupha ukungcola kunye nokukhangela. ukuguquguquka kwevalve yokhuseleko.
Indlela echanekileyo yokusebenza kwevalve yokukhupha amanzi
Ivalve yokukhupha amanzi kulula ukuba ivalwe lungcoliseko lwamanzi kunye nezinye ii-sandries. Xa isetyenziswa, qala uvule ivalve yokugungxula kwaye ugungxule umbhobho. Ukuba kukho umbhobho we-bypass, ivalve ye-bypass ingavulelwa ukugungxula okufutshane. Kwivalve yokukhupha ngaphandle kombhobho wokugungxula kunye nombhobho we-bypass, ivalve yokukhupha ingasuswa. Emva kokuvula ivalve yokuvala, vala ivalve yokuvala, faka ivalve yokukhupha amanzi, kwaye emva koko uvule ivalve yokuvala ukuze uvule ivalve.
Ukusebenza ngokuchanekileyo kwevalve yokunciphisa uxinzelelo
Phambi kokuba kuvulwe ivelufa yokunciphisa uxinzelelo, ivalve yokudlula okanye ivelufa yokugungxula iya kuvulwa ukucoca ukungcola kumbhobho. Emva kokuba umbhobho ucociwe, ivalve yokudlula kunye nevalve yokugungxula iya kuvalwa, kwaye ivelufa yokunciphisa uxinzelelo iya kuvulwa. Ezinye iivalve zokunciphisa uxinzelelo lomphunga zineevalve zombhobho phambi kwazo, ekufuneka zivulwe kuqala, emva koko uvule kancinci ivalve esikiweyo emva kwevalve yokunciphisa uxinzelelo, ekugqibeleni uvule ivalve esikiweyo phambi kwevalve yokunciphisa uxinzelelo, jonga. igeyiji yoxinzelelo ngaphambili nangasemva kwevalve yokunciphisa uxinzelelo, hlengahlengisa isikrufu esilawulayo sevalve yokunciphisa uxinzelelo ukwenza uxinzelelo ngasemva kwevalve lufikelele kwixabiso elimiselweyo, emva koko uvule ngokucothayo ivalve yokusika emva kwevalve yokunciphisa uxinzelelo, kwaye ulungise uxinzelelo emva kwevalve ide yaneliseke. Lungisa i-screw yokulungisa kwaye uvale i-cap yokukhusela.
Ukuba ivalve yokunciphisa uxinzelelo iyasilela okanye ifuna ukulungiswa, vula ngokucothayo ivalve yokudlula kuqala, vala ivalve yokuvala ngaphambili ngaxeshanye, uhlengahlengise ngokufanelekileyo ivalve ye-bypass ngesandla, ukuze uxinzelelo olusemva kwevalve yokunciphisa uxinzelelo luzinze. kwixabiso lokusetwa kwangaphambili, kwaye emva koko uvale ivalve yokunciphisa uxinzelelo ukuze utshintshe okanye ulungiswe, kwaye ubuyele kwesiqhelo.
Ukusebenza ngokuchanekileyo kwevalve yokukhangela
Ukuze ugweme amandla aphezulu empembelelo ngeli xesha xa i-valve yokukhangela ivaliwe, i-valve kufuneka ivalwe ngokukhawuleza ukuthintela ukubunjwa kwesantya esikhulu sokubuyela umva, isizathu sokubunjwa koxinzelelo lwempembelelo xa i-valve ivalwe ngokukhawuleza. . Ngoko ke, isantya sokuvala sevalve kufuneka sihambelane ngokuchanekileyo kunye nesantya sokunciphisa isantya se-downstream medium.
