1.Zvosecheki mavharuvhuingowana unidirectional yekuvhara-kuvharika uye otomatiki kuvhurika nekuvhara zvichienderana nekumanikidza musiyano wepakati. Havana kukurumidza kudzora basa uye vanowanzo kanganisa kana yakavharwa. Ivhavha yekuongorora yemvura inowedzera inononoka-kuvhara anti-sando dhizaini pahwaro hwekucheka-kubvisa basa. Nekushandisa mudziyo wakatsaurirwa kudzora kumhanya kwekuvhara kwevhavha disc, inogona kuderedza nyundo yemvura kukanganiswa panguva yekudzokera kumashure uye kuchengetedza sisitimu michina. (Mufananidzo: DN1200).tilting cheki vharafu ine uremu sando）

2.Kusiyana kwemaitiro ekuumbwa

A common check valve ine chimiro chakareruka, chinosanganisira muviri wevhavha, disc, chigaro chevhavha uye reset mechanism (spring kana giravhiti). Kuvhura kwayo nekuvhara kunoenderana zvachose nekusunda kwepakati. Iyo micro-resistance inononoka-inovhara yeflanged cheki vharafu inoshongedzerwa inononoka-yekuvhara yekudzora meshini (yakadai se hydraulic damping uye spring buffer components) pane iyi nheyo, iyo inogona kuvhara mumatanho (kutanga nekukurumidza kuvhara 70% -80%, uye zvishoma nezvishoma kuvhara chikamu chakasara).

(Mufananidzo: DN700 inorereka cheki vharafu ine uremu sando)

3.Fluid Resistance uye mvura sando Kudzora

Pamusana pekugadzirisa kwemaitiro, iyo inowanzotarisa chekivhavha ine chiyero chakakura chekudzivirira mberi uye kukurumidza kuvhara (0.5 kusvika ku1 yechipiri), iyo inogona kukonzera nyore nyore nyundo yemvura yakaoma, kunyanya kuisa dambudziko guru mu-high-pressure uye high-flow systems. Iyo butterfly cheki vharafu inoderedza kupikisa kwepamberi (kureva, "micro-resistance") kuburikidza neyakagadziriswa dhizaini uye inowedzera nguva yekuvhara kusvika 3-6 masekonzi, iyo inogona kudzora peak mvura sando mukati 1.5 nguva kushanda nesimba uye zvakanyanya kunetesa kukanganisa.

4.Mamiriro akasiyana anoshanda

Mavharuvhu ekutarisa akajairika anokodzera mamiriro ane kuderera kwakadzika (≤1.6MPa), kuyerera kudiki (pombi dhayamita ≤DN200), uye kusanzwa kune sando yemvura, senge mapaipi ebazi ekugovera mvura yemumba uye zvitubu zvemvura inopisa. Iyo micro-resistance inononoka-inovhara isina kudzoka valve yakakodzera kune yakakwirira-pressure (≥1.6MPa) uye yakakura-kuyerera (pombi dhayamita ≥DN250) masisitimu, akadai seakakwira-kukwira chivako chemvura yemoto, mahombe epombi, maindasitiri anotenderera emvura masisitimu uye mamwe mamiriro akakosha.

5.Maintenance uye Mari

Mavharuvhu echeki akajairwa haana zvishongedzo zvakaoma, zvine mwero wakaderera wekutadza, zviri nyore kuchengetedza uye zvine mutengo wakaderera. Nekuda kwekuvapo kweinononoka-yekuvhara mashini, iyo micro-resistance inononoka-kuvhara yekuvhara yevhavha inogona kusangana nezvinetso zvakadai sekunyorovesa mafuta kuvuza uye kuchembera kwechirimo, zvichikonzera kukwira zvishoma kwekugadzirisa frequency uye mutengo. Nekudaro, tichifunga nezvesesese system kuchengetedza basa, inopa zvirinani mutengo kuita mumamiriro akaomarara.

Naizvozvo, musiyano wepakati pakati pezviviri izvi uri pakuti vane inononoka-kuvhara-inovhara-sando basa: akajairwa cheki mavharuvhu anotarisa pane yekutanga kuvharika, nepo micro-resistance inononoka-kuvhara-yekuvhara cheki mavharuvhu anowana kushomeka kwekudzivirira uye kushomeka kushomeka kuburikidza nekugadzirisa kwemaitiro, zvichiita ivo sarudzo inosarudzika kune yakakwirira-kudzvanywa uye yakakwirira-kuyerera masisitimu.

Semugadziri wevharuvhu ane makore makumi maviri echiitiko, Jinbin Valve yagara ichivimbisa kunaka kwezvigadzirwa nemasevhisi ayo. Kana iwe uine chero chaunoda, ndapota taura nesu pazasi uye iwe uchagamuchira mhinduro mukati meawa makumi maviri nemana!
