Kodi mitundu ndi zofunikira za ma valve oyesera ndi ziti?

Ma valve oyesera amapezeka m'mitundu yosiyanasiyana malinga ndi zinthu monga kapangidwe kake, zinthu zomwe zimagwiritsidwa ntchito, ndi momwe amagwiritsidwira ntchito. Izi ndi chidule chatsatanetsatane cha mitundu ndi ma specification a ma valve oyesera:

Choyamba, mtundu

1. Kugawa magulu malinga ndi kapangidwe kake

Valavu yoyezera chikweza: Valavu yoyezera yokhala ndi diski yotsetsereka pamzere wapakati wa thupi. Valavu iyi ikhoza kuyikidwa pa chitoliro chopingasa chokha, mphamvu yolimbana ndi madzi imakhala yayikulu. Pamene sing'anga ili m'mbali mwa madzi, diski ya valavu imatsegulidwa ndi mphamvu ya sing'anga. Sing'anga ikasiya kuyenda, diski ya valavu imagwera pampando ndi kulemera kwake kuti sing'angayo isagwere. Valavu yoyezera chikweza ili ndi mitundu iwiri ya yolunjika ndi yowongoka, valavu yoyezera chikweza yolunjika yapakati ndi njira yotulukira ndi njira ya mpando yolunjika, ndi valavu yoyezera chikweza yolunjika yapakati ndi njira yotulukira ndi njira ya mpando ndi njira yofanana, kukana kwake kuyenda ndi kochepa kuposa mtundu wowongoka.

Valavu yowunikira yozungulira: Valavu yowunikira yokhala ndi diski yooneka ngati diski komanso kuyenda kozungulira kuzungulira shaft yozungulira ya njira ya mpando. Kukana kwake nthawi zambiri kumakhala kochepa kuposa valavu yowunikira yokweza, yoyenera nthawi zazikulu. Valavu yowunikira yozungulira imatha kugawidwanso m'ma valavu amodzi, ma valavu awiri ndi ma valavu ambiri malinga ndi kuchuluka kwa ma valavu, cholinga chachikulu ndikuletsa kuti sing'anga iyimitse kuyenda kapena kubwerera m'mbuyo, zomwe zimapangitsa kuti mphamvu ya hydraulic isakhudze.

Valavu yoyezera gulugufe: Valavu yoyezera yokhala ndi diski yozungulira pini pampando. Valavu yoyezera diski ndi yosavuta, imatha kuyikidwa pa chitoliro chopingasa chokha, ndipo ili ndi kutseka kosakwanira.

Valavu yoyesera mapaipi: Valavu yoyesera yokhala ndi diski yotsetsereka pakati pa thupi. Ndi valavu yatsopano yomwe yangotuluka kumene, yaying'ono, yolemera pang'ono, ukadaulo wabwino wogwiritsira ntchito, ndi imodzi mwa njira zopangira mavavu oyesera.

Valavu yowunikira kuthamanga: Valavu iyi ili ndi ntchito yofanana ndi valavu yowunikira kukweza ndi valavu yozungulira kapena valavu ya Angle, ndipo nthawi zambiri imagwiritsidwa ntchito ngati valavu yodulira madzi ndi nthunzi yothira boiler.

Mitundu ina: Ikuphatikizaponso valavu yowunikira mtundu wa kulemera, valavu yowunikira mtundu wa mbale, valavu yowunikira diski ya brake, valavu yowunikira mtundu wa mpira, valavu yowunikira mtundu wa diaphragm.

2. Sanjani malinga ndi zinthu

Valavu yowunikira zitsulo: monga valavu yowunikira zitsulo zotayidwa, valavu yowunikira zamkuwa, valavu yowunikira zitsulo zosapanga dzimbiri, valavu yowunikira zitsulo za kaboni, valavu yowunikira zitsulo zopangidwa, ndi zina zotero.

Valavu yoyesera yopanda chitsulo: monga valavu yoyesera ya pulasitiki, valavu yoyesera ya FRP, ndi zina zotero.

3. Gawani m'magulu malinga ndi ntchito

Valavu yoyang'anira chete: monga valavu yoyang'anira chete ya DRVZ, valavu yoyang'anira chete ya DRVG, valavu yoyang'anira chete ya NRVR, ndi zina zotero.

Valavu yoyesera yapadera: monga valavu yoyesera ya rabara ya SFCV, valavu yoyesera ya DDCV double flap, ndi zina zotero.

Chachiwiri, specifications

Mafotokozedwe a valavu yofufuzira nthawi zambiri amafotokozedwa ndi mainchesi odziwika bwino (DN), ndipo mafotokozedwe odziwika bwino ndi DN15, DN25, DN50, DN80, DN100, DN150, ndi zina zotero. Kuphatikiza apo, pali mafotokozedwe monga kuchuluka kwa kuthamanga, mitundu yolumikizira (monga maulumikizidwe a ulusi, opindika, owelulidwa ndi omangirira).

Mwachitsanzo, tsatanetsatane wa valavu yowunikira ulusi wamkati wa H12W ndi DN15-100mm, ndipo kalasi yowunikira ndi 1.6-32MPa; tsatanetsatane wa mavalavu owunikira a gulugufe a H76H ndi H76W awiri-disc ndi DN50-1200mm, ndipo kalasi yowunikira ndi 1.6-10MPa.

Chachitatu, sankhani malingaliro

Posankha valavu yoyezera, ndikofunikira kuganizira zinthu monga njira yeniyeni yoyezera mapaipi, mawonekedwe apakati, kuthamanga kwa ntchito ndi kutentha. Nazi zina mwazosankha:

Sankhani mtundu woyenera wa valavu yoyezera ndi zofunikira zake malinga ndi momwe madzi akuyendera komanso kukula kwa madziwo.

Ganizirani za dzimbiri la sing'anga, kukhuthala ndi kutentha ndi zina, sankhani zinthu zoyenera.

Sankhani njira yoyenera yolumikizira kutengera malo oyika ndi zofunikira pakukonza mapaipi.

Onani kabukhu ka zinthu za wopanga ndi pepala la ukadaulo kuti muwonetsetse kuti valavu yofufuzira yomwe mwasankha ikukwaniritsa zofunikira za dongosolo.

Mwachidule, pali mitundu yosiyanasiyana ndi mafotokozedwe a ma valve oyesera, ndipo kusankha kuyenera kuganiziridwa mokwanira malinga ndi zosowa zenizeni.
