Yintoni ivalve yesango? Sisixhobo esivalayo sokuvula nokuvala ukuhamba kolwelo olugqithiswa yinkqubo yemibhobho (okanye umbhobho). Ivalve yesango sisivalo esimacala amabini, njengoko ulwelo lunokuqukuqela nakweliphi na icala. Ukufakwa kolu hlobo lwevalve kudala ukuhla koxinzelelo oluthobekileyo kumbhobho, ongaphantsi kweevalvu zeglowubhu. Iivalvu zesango ziye zakha imizimba yobukhulu obungaphantsi kwee-intshi ezi-2 (API 602 / BS 5352), kunye nemizimba ephosiweyo yobukhulu obukhulu (API 600, API 603, API 6D).

Iinzuzo eziphambili zolu hlobo lwesivalo zezi:
Kulula ukugcina kunye nokuqhaqha
Eyona ilungileyo njengevalve yokuvala
Indlela ezimbini
Ixabiso eliphantsi
Ingasetyenziswa kunye ne-slurries kunye ne-viscous liquids
Ifumaneka ngobukhulu obukhulu
Ngokwemvelo ikhuselekile emlilweni (xa isetyenziswa ngentsimbi)
Izinto ezingeloncedo zezi:
Ixesha elicothayo lokuvula kunye nokuvala
Izithintelo zoxinzelelo oluphantsi
Ukukhukuliseka kwesihlalo kunye nediski kunokwenzeka
Iimpawu zokubetha kakubi
Kunzima ukulungisa
IINTLOBO zevalve yesango
PHOSSA intsimbi
Olu lolona hlobo luqhelekileyo, olugutyungelwe yi-API 600 (i-carbon kunye ne-alloy steel) kunye ne-API 603 (insimbi engenasici kunye namabakala aphezulu) iinkcukacha. Iivalvu zesango lentsimbi yentsimbi ziyafumaneka ngobukhulu obungaphezulu kwe-intshi ezi-2, ukuya kuthi ga kwi-intshi ezingama-80.
Intsimbi EYENZIWEYO
Iivalvu zentsimbi ezibunjiweyo zisetyenziselwa imibhobho encinci yokubhobhoza, ngokubanzi ngaphantsi kwee-intshi ezi-2 ububanzi. Iimpawu ze-API 602 kunye ne-BS 5352 zigubungela olu hlobo lweevalvu zesango.
API 6D YEMIbhobho (THROUGH-CONDUIT)
Ezi zivalo zesango zemibhobho kwaye zifumaneka kwidizayini ezimbini eziphambili, i-slab kunye nesango elikhulayo.
UXINZELELO Ltywina
Iivalvu zesango lokutywinwa koxinzelelo zisetyenziselwa ukusetyenziswa koxinzelelo oluphezulu. Ezona ntlobo zixhaphakileyo zeevalvu zokusetyenziswa koxinzelelo oluphezulu yi wedge eguquguqukayo kunye ne-parallel slide pressure valve valve. Zifumaneka ngokubanzi kunye nemizimba etyhidiweyo okanye i-forged, kwimilinganiselo ukusuka kwi-2 ukuya kwi-intshi ezingama-24 kunye noxinzelelo loxinzelelo ukusuka ku-600 # ukuya ku-4500 #, kunye ne-socket weld okanye i-butt weld, iziphelo zokuqinisekisa uqhagamshelo oludibeneyo oludibeneyo (kodwa iziphelo ezine-flanged nazo zinokwenzeka).
