Thechekeni valavundi chinthu chofunikira chowongolera chomwe chimagwiritsidwa ntchito poletsa kutuluka kwamadzimadzi. Nthawi zambiri imayikidwa potulukira chitoliro cha madzi ndipo imalepheretsa madzi kubwereranso. Pali mitundu yambiri ya valavu yoyang'ana, lero chiyambi chachikulu ndi valavu yoyang'ana mbale ziwiri ndi swing valve check valve mu valve yofewa yosindikizidwa. Valavu yosindikizira yofewa imagwiritsa ntchito zida zosindikizira kuti zisindikize mpando wa valve kuti ukhale wodalirika.
Choyamba, yambitsani valavu yoyendera mbale ziwiri. Avalavu yoyendera mbale ziwirindi makina omwe amagwiritsidwa ntchito poyang'anira kutuluka kwa madzi kapena mpweya. Zimagwira ntchito pozungulira valavu kuti muteteze kutuluka kwamadzimadzi. Ma valve oyendera ma mbale awiri nthawi zambiri amagwiritsidwa ntchito popopera madzi, ma hydraulic system, ndi makina a pneumatic kuteteza kubweza kwamadzi ndi kutayikira.
Valavu yoyang'ana mbale ziwiri imakhala ndi ma cloe awiri, imodzi imatchedwa inlet ndipo ina imatchedwa chotulukira. Pamene chimbale cholowera chikuzungulira, chimbalecho chimatseguka kuti chilole kutuluka kwamadzimadzi. Kenako, diski yotulutsa ikazungulira, chimbalecho chimatseka kuti madziwo asabwererenso ku chitoliro cholowera. Choncho, valavu yoyang'ana pawiri-plate imatha kuyendetsa bwino kayendedwe ka madzi. Ndi yosavuta komanso yosavuta kukhazikitsa ndi kukonza. Nthawi zambiri amapangidwa ndi chitsulo ndipo amakhala ndi kukana bwino kwa dzimbiri komanso kukana kuvala.
Dual plate check valve yakhala ikugwiritsidwa ntchito kwambiri m'mafakitale ndi mafakitale osiyanasiyana. M'makampani amafuta ndi gasi, amagwiritsidwa ntchito posungira ndi kunyamula zakumwa ndi mpweya. M'makampani opanga mankhwala, amagwiritsidwa ntchito kuwongolera kuchuluka kwa mankhwala. M'mafakitale amagetsi ndi magetsi, amagwiritsidwa ntchito kuteteza zida zamagetsi ndi gridi yamagetsi. Kuphatikiza apo, ma valve oyendera mbale awiri amagwiritsidwanso ntchito kwambiri m'malo am'nyumba ndi malonda kuti aziwongolera kutuluka kwamadzi monga madzi, gasi ndi mpweya.
Chachiwiri ndivalavu yoyendera. Valavu yoyang'ana swing ndi valve yomwe imagwiritsidwa ntchito poletsa kutuluka kuti zisabwererenso. Zimagwira ntchito chifukwa pamene madzi akudutsa muzitsulo za swing check valve, kutuluka kwake kumayendetsedwa ndi mphamvu yakunja yomwe imapangitsa kuti diskiyo ikhale yozungulira pamzere wotsogolera mpando, kuteteza kuchira kwa disc ndikulepheretsa kutuluka kubwerera. Ma valve oyendetsa ma swing nthawi zambiri amagwiritsidwa ntchito m'mapaipi amadzi ndi ngalande, makamaka m'nyumba zokwera, malo okhala, mafakitale ndi malo ena omwe amafunikira kuti madzi asabwererenso. Valve ili ndi dongosolo losavuta, kukhazikitsa kosavuta, kugwiritsa ntchito kodalirika, ndipo kumagwiritsidwa ntchito kwambiri mu dongosolo la chitoliro cha madzi.
Ngakhale kuti mawonekedwe a valve ndi ophweka, mavuto ena amafunika kuyang'anitsitsa panthawi yogwiritsira ntchito. Valve yowunikira ndi chinthu chofunikira kwambiri chowongolera, chomwe chingalepheretse bwino kutuluka kwamadzimadzi ndikuteteza magwiridwe antchito amadzi. Ngakhale kuti mawonekedwe a valve yowunikira ndi ophweka komanso osavuta kugwiritsa ntchito, mfundo zotsatirazi ziyenera kuperekedwa pa nthawi ya kukhazikitsa: choyamba, valve yowunikira iyenera kuikidwa pa chitoliro chopingasa ndikusungidwa kutali ndi valve yowonjezera ndi mpope; kachiwiri, kukula kwa valavu cheke kuyenera kufanana ndi kukula kwa chitoliro; potsiriza, valavu yoyang'ana iyenera kukhazikitsidwa molondola pakuyenda kwa madzi.

Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
