Valavu Yoyang'anira Magalimoto Yapamwamba Kwambiri Yopangira Magalimoto ndi Zolemera Zozungulira China Wopereka fakitale Wopanga
Kodi valavu yoyezera mkono ndi kulemera kwa lever ndi chiyani?
Valavu yowunikira mkono ndi kulemera kwa leverndi mtundu wa valavu yoyang'anira swing yokhala ndi silinda ya mpweya kuti isagwe ndi madzi.itIli ndi thupi la valavu, bonnet, ndi diski yolumikizidwa ku hinge. Disikiyo imasuntha kuchoka pa mpando wa valavu kuti ilole kuyenda kupita kutsogolo, ndikubwerera ku mpando wa valavu pamene kuyenda kwa mmwamba kwayimitsidwa, kuti ipewe kuyenda kwa mmbuyo. Imalola kuyenda kwathunthu, kosatsekedwa ndipo imatseka yokha pamene kuthamanga kwa mpweya kukuchepa. Ma valavu awa amatsekedwa kwathunthu pamene kuyenda kwa mpweya kufika pa zero ndikuletsa kuyenda kwa mpweya kubwerera.
tValavu imapangidwa ndi chitsulo chosungunuka, chitsulo chosungunuka, imagwiritsidwa ntchito makamaka popereka madzi ndi ngalande, komanso m'magawo ena a mafakitale a payipi kuti apewe kuponderezana kwapakati pa kuthamanga kochepa komanso kutentha kwabwinobwino.Ikhoza kuyikidwa ndi zida zowongolera kutseka monga Air Cushioned Cylinder, Oil Controlled Cylinder, Bottom Mounted Buffer, Lever & Spring ndi Lever & Weight.
Zinthu zazikulu za lever arm ndi weight swing check valve
Makhalidwe ndi ubwino waValavu yowunikira mkono ndi kulemera kwa lever
- * Ntchito yopanda mavuto komanso yosavuta kuyisamalira
- *Malo odzaza ndi madzi, kukana kwa madzi kutsika.
- *Yoyikidwa ndi silinda ya cushion ndi kulemera kwa lever, yolumikizidwa ndi disc ndi shaft yomweyo. Nthawi yotseguka ndi yotseka kapena liwiro zitha kusinthidwa powongolera valavu ndi kulemera kwa slide.
- *Kutseka magwiridwe antchito ake kumakhala kokhazikika, kodalirika komanso kolimba. Kugwiritsidwa ntchito kwa nthawi yayitali, Palibe kugwedezeka, Palibe phokoso.
Mtsogoleri wa ntchito Valavu yowunikira mkono ndi kulemera kwa lever:
- 1. Pamene chitoliro chakumtunda chikuwonjezera mphamvu ya madzi, valavu ya diski idzatsegulidwa.Chingwe cha disc chidzayendetsa pistoni ya silinda ndi lever ndikuwonjezera kulemera.
- 2. Pamene kuthamanga kwa madzi akumtunda kwakwera kuposa kuthamanga kwa valavu, valavu ya disc idzatsegulidwa. Pistoni ya silinda idzatsegulidwa ndikupumira. Pamene kuthamanga kwa madzi akumtunda kwaima kapena kuthamanga kwa kumbuyo, valavu ya disc idzayandikira mwachangu ndi kulemera kwa diski, kulemera kwa lever ndi kuthamanga kwa kumbuyo. Pistoni ya silinda yagwa pansi ndipo mpweya mkati mwa silinda udzayamba kupanga mphamvu yonyowa. Kutseka kwambiri mpando wa valavu, mphamvu yonyowa kwambiri inachitika. Pamene diski yatsekedwa kufika pa 30% yotseguka, mphamvu yonyowa idzawonjezeka kwambiri. Disiki idzayamba kutseka pang'onopang'ono.
