N'chifukwa chiyani mumasankha valavu ya globe yachitsulo chopangidwa ndi chitsulo

Ma valve a globe achitsulo chopangidwaagawika m'magulumavavu a globe achitsulo cha kaboni chopangidwa ndi kabonindimavavu a globe achitsulo chosapanga dzimbiri, nthawi zambiri amagwiritsidwa ntchito pamavuto apamwamba komanso apakati (150lb-800lb, 1500LB, 2500LB), komanso pamavuto apamwamba komanso otsika (-196℃ ~ 700℃), mavalavu achitsulo opangidwa ndi chitsulo ali ndi mphamvu zambiri komanso mawonekedwe abwino amakina kuti akwaniritse zofunikira pamavuto apamwamba. Koma amangogwiritsidwa ntchito pakupanga, nthawi zambiri amagwiritsidwa ntchito pakukula kochepa komanso kwapakati (1/2 “, 3/4 “, 1 “, 1-1/4 “, 1-1/2 “, 2, 2-1/2 “, 3 “ndi 4”).

Ntchito ya Valve ikhoza kukhala yamanja, giya la bevel, actuator ya pneumatic, actuator yamagetsi, actuator ya hydraulic, pneumatic-hydraulic, electro-hydraulic.

Ubwino wa kapangidwe ka vavu ya globe yachitsulo chopangidwa ndi chitsulo

1. Valavu yozungulira yachitsulo chopangidwa ndi chitsulo imagwiritsa ntchito chisindikizo chodzilimbitsa chokha, ndipo malekezero onse awiri a chitoliro cha nthambi ya thupi la valavu amalumikizidwa.

2. Mpando wa valavu ya globe yachitsulo chopangidwa ndi chitsulo, pamwamba pake potseka ma diski a valavu amapangidwa ndi kuwotcherera kwa plasma kopangidwa ndi cobalt-based cemented carbide, kukana kukalamba, komanso kukana kukwawa kwambiri.

3. Chitsinde cha valavu chimachiritsidwa ndi nitriding yolimbana ndi dzimbiri, yomwe imakhala ndi kukana bwino dzimbiri komanso kukana kukwawa.

4 mu ndondomeko yotsegulira ndi kutseka, chifukwa cha valavu disc mu thupi la valavu, kukangana pamwamba kumakhala kochepa, ndipo kukana kuvala kumakhala kochepa.

5. Nthawi zambiri pamakhala nkhope imodzi yokha yotsekera pa thupi la valavu ndi diski, kotero njira yopangira ndi yabwino komanso yabwino yosamalira

Vavu iyenera kuyang'aniridwa musanayike, ndipo muyezo wa kapangidwe ka vavu uyenera kukhala wogwirizana ndi muyezo wapadziko lonse wa API 602. Kuyesa kwa mphamvu ndi kulimba kuyenera kuchitika musanayike.

Mu mayeso a mphamvu, kuthamanga kwa mayeso ndi nthawi 1.5 kuposa kuthamanga kwapadera, ndipo nthawi yake si yochepera mphindi 5.

Chigoba cha valve ndi kutseka mpando wakumbuyo ziyenera kukhala zoyenerera popanda kutayikira.

Kuyesa kusindikiza, kuthamanga kwa mayeso ndi nthawi 1.1 ya kuthamanga kwa dzina;

Kupanikizika kwa mayeso mu nthawi yoyeserera kuyenera kukwaniritsa zofunikira za muyezo wa API 598, popanda kutayikira pamwamba pa chitseko cha disc monga momwe zayenerere.
