Kodi Cheki Vavu ndi Chiyani: Kumvetsetsa Zoyambira Zake, Ntchito

A Check Valvendi valavu yomwe imatsegula ndi kutseka diski ya valve ndi kutuluka kwa sing'anga yokha kuti ateteze sing'angayo kuti isabwererenso. Imatchedwanso valavu yosabwerera, valavu ya njira imodzi, valve yobwerera kumbuyo kapena kumbuyo kwa valve. Valavu yoyendera ndi ya gulu la ma valve otomatiki. Ntchito yake yayikulu ndikuletsa sing'anga kuyenderera mmbuyo, kuteteza mpope ndi mota yoyendetsa kuti zisabwerere, ndikumasula sing'anga ya chidebe. Kuonjezera apo, valve yowunikira ingagwiritsidwenso ntchito pa payipi yomwe imapereka chithandizo ku dongosolo lothandizira komwe kupanikizika kungathe kukwera kupitirira kuthamanga kwa dongosolo.

Mfundo yogwirira ntchito ya valve cheke

Gawo lotsegula ndi lotseka la valve yotsegula ndi diski yozungulira yozungulira, yomwe imagwira ntchito ndi kuthamanga kwapakati pawokha komanso kufa kwa diski ya valve kuti atseke kumbuyo kwapakati. Pamene sing'anga imalowa kuchokera kumapeto, valve disc imatsegulidwa ndipo sing'anga imatha kudutsa bwino; pamene sing'anga imabwerera mmbuyo, valavu ya valve imatseka ndi kufa ndi kutuluka kwa madzi kuti asateteze sing'anga kubwerera.

Kugawika kwa ma cheki ma valve

Ma valve owunika amatha kugawidwa m'magulu otsatirawa malinga ndi kapangidwe kawo ndi njira yoyika:

Chovala chowunikira chokweza:

Vavu disc imatsetsereka pamzere woyimirira wapakati wa thupi la valavu, yoyenera mapaipi opingasa, ndipo imakhala ndi kukana kwakukulu kwamadzimadzi.

Chovala chowongolera cha swing:

Disiki ya valve imakhala yofanana ndi disc ndipo imazungulira kuzungulira shaft yozungulira ya mpando wa valve. Kukana koyenda kumakhala kochepa ndipo ndikoyenera nthawi zazikulu zokhala ndi kutsika kochepa komanso kusintha kosasintha.

Valve yowunikira yawafer:

Disiki ya valve imazungulira mozungulira shaft ya pini pampando wa valve. Ili ndi dongosolo losavuta ndipo likhoza kuikidwa pamapaipi opingasa. Kusindikiza sikuli bwino.

Valavu yowunikira mapaipi:

Disiki ya valve imayenda pakati pa mzere wapakati wa thupi la valve. Ili ndi kukula kochepa, kulemera kwake ndi luso labwino lopangira.

Valve ya compression check:

Lili ndi ntchito zonse za valavu yonyamulira ndi valavu yoyimitsa kapena valavu.

Zochitika zantchito

Onani ma valveamagwiritsidwa ntchito kwambiri pazochitika zosiyanasiyana komwe kuli koyenera kuteteza kubwereranso kwa mauthenga, monga valavu yapansi ya chipangizo chopopera, kutuluka kwa mpope, ndi njira yotulutsa chidebe. Chifukwa cha mawonekedwe ake otsegula ndi kutseka, valavu yowunikira imatha kuletsa bwino kubweza kwa media panthawiyi ndikuteteza magwiridwe antchito a zida ndi machitidwe.
