Mavavu opangidwa ndi zitsulo amagawidwa kukhala ma valve opangidwa ndi carbon steel globe ndi mavavu opangidwa ndi zitsulo zosapanga dzimbiri, nthawi zambiri amagwiritsidwa ntchito pazovuta zazikulu komanso zapakati (150lb-800lb, 1500LB, 2500LB), komanso nthawi yotentha komanso yotsika (-196 ℃ ~ 700 ℃), mavavu achitsulo opangidwa amakhala ndi mphamvu zapamwamba komanso makina abwinoko kuti athe kuthana ndi kuthamanga kwambiri. zofunika. Koma zochepa pakupanga, nthawi zambiri zimangogwira ntchito zazing'ono ndi zazing'ono (1/2 ", 3/4", 1 ", 1-1 / 4", 1-1 / 2 ", 2, 2-1 / 2" ", 3" ndi 4 "). Ntchito ya Valve imatha kukhala yamanja, zida za bevel, pneumatic actuator, actuator yamagetsi, hydraulic actuator, pneumatic-hydraulic, electro-hydraulic.

Kampani ya Newsway Valve yopanga zitsulo zopangira ma valve padziko lonse lapansi ndi motere:

1. Vavu yachitsulo yopangidwa ndi zitsulo imagwiritsa ntchito chisindikizo chodzilimbitsa, ndipo malekezero onse a chitoliro cha nthambi ya valavu amawotchedwa.

2. Mpando wa valavu yachitsulo ya globe valve, valve disc yosindikiza pamwamba imapangidwa ndi cobalt-based cemented carbide plasma spray kuwotcherera, kukana kuvala, kukana kwa abrasion.

3. Tsinde la valve limathandizidwa ndi nitriding resistance resistance, yomwe ili ndi kukana kwabwino kwa dzimbiri komanso kukana abrasion.

4 potsegula ndi kutseka, chifukwa cha valavu chimbale mu valavu thupi kusindikiza pamwamba kukangana ndi yaing'ono, ndi kuvala kukana.

5. Kawirikawiri pali nkhope imodzi yokha yosindikizira pa thupi la valve ndi diski, kotero kuti kupanga kupanga kumakhala bwino komanso kosavuta kukonza.

Valavu iyenera kuyang'aniridwa musanakhazikitsidwe, ndipo ndondomeko ya mapangidwe a valve iyenera kukhala yogwirizana ndi API 602 yapadziko lonse lapansi. Mu mayeso a mphamvu, kuthamanga kwa mayeso ndi nthawi 1.5 ya kukakamiza mwadzina, ndipo nthawiyo si yochepera 5min. Chigoba cha valve ndi kulongedza ziyenera kukhala zoyenerera popanda kutayikira. Kuyesa kusindikiza, kukakamiza koyesa ndi nthawi 1.1 ya kukakamiza mwadzina; Kupanikizika kwa mayeso mu nthawi yoyeserera kuyenera kukwaniritsa ZOFUNIKIRA za API 598 muyezo, popanda kutayikira pa disc yosindikizira ngati koyenerera.
