Wafer cheki mavharuvhuanozivikanwawo semavharuvhu ekudzokera shure, mavharuvhu ekumashure, uye mavharuvhu ekumashure.Aya marudzi emavharuvhu anovhurwa otovharwa nechisimba chinogadzirwa nekuyerera kwepakati pachayo mupombi, yerudzi rweotomatiki valve.
Ivhavha yekuongorora ndeyekuvimba nekuyerera kwepakati pachayo uye inovhura uye inovhara chivharo chevhavha, inoshandiswa kudzivirira yepakati backflow valve, inonziwo check valve, check valve, backflow valve, uye back pressure valve.Ivhavhavha yecheki ndeyerudzi rweotomatiki valve, basa rayo guru nderekudzivirira midhiya kudzoka, kudzivirira pombi uye kutyaira mota kudzoreredzwa, pamwe nemudziyo media discharge.Cheki mavharuvhu anogona zvakare kushandiswa kupa kudzvanywa kunogona kukwira kune yakawanda kupfuura iyo system yekumanikidza yeanobatsira system kupa pombi yekugovera.Ivhavhavha yekuongorora inogona kugoverwa kuva swing check valve (maererano nepakati pekutenderera kwegiravhiti) uye cheki cheki chepamusoro (inofamba pamwe chete neaxis).
Kutanga, kushandiswa kwe-clip-on check valve check valve yakaiswa mupiping system, basa rayo guru nderokudzivirira midhiya kudzoka shure, cheki valve imhando yevhavha yega yega inotsamira pakumanikidzwa kwevhidhiyo kuzarura nekuvhara.Clamp cheki vharafu inokodzera zita rekumanikidza PN1.0MPa ~ 42.0MPa, Kirasi150 ~ 25000, dhayamita dhayamita DN15 ~ 1200mm, NPS1/2 ~ 48, tembiricha yekushandisa -196 ~ 540 ℃ yemapaipi akasiyana-siyana, anoshandiswa kudzivirira media backflow.Kuburikidza nekusarudzwa kwezvinhu zvakasiyana-siyana, zvinogona kuiswa kumvura, steam, mafuta, nitric acid, acetic acid, yakasimba oxidizing media uye uric acid uye mamwe midhiya.
Zvinhu zvikuru zvewafer cheki valve ndeye carbon simbi, yakaderera-tembiricha simbi, duplex simbi (SS2205/SS2507), titanium alloy, aluminium bronze, Inconel, SS304, SS304L, SS316, SS316L, chrome-molybdenum simbi, Monel (400/ 500), 20 # alloy, Hastelloy uye zvimwe simbi zvinhu.
Chechitatu, zviyero uye zvigadziro zvewafer cheki valve

Chechina, maitiro ekuumbwa kwepinch check valve
1.Short chimiro kureba, chimiro chayo kureba ingori 1/4 ~ 1/8 yechinyakare swing flange cheki vharafu.
2. vhoriyamu diki, uremu huremu, uremu hwayo ingori yechinyakare flange cheki vharafu 1/4 ~ 1/2
3. valve flap inovhara nekukurumidza, mvura sando yekumanikidza idiki
4. Horizontal kana vertical piping inogona kushandiswa, nyore kuisa
5. Smooth flow path, low fluid resistan
6.Sensitive chiito, kushanda zvakanaka kwekuisa chisimbiso
7.Disc sitiroko ipfupi, yekuvhara maitiro idiki
8.Chimiro chese chiri nyore uye chakabatana, uye chimiro chakanaka
9. Hupenyu hurefu hwebasa uye kushanda kwakavimbika
shanu.Kuisa chisimbiso kwevhavha yewafesi yekutarisa Iyo yakapfava-yakavharwa wafer cheki vharafu inogona kuwana zero kuvuza, asi yakaoma-yakavharwa wafer cheki vharafu haisi zero-leakage valve.Iine imwe leakage rate.Zvinoenderana nechiyero chekuongorora che API598, chekivhavha ine chigaro chesimbi, yehukuru hweDN100, chiyero chekubuda kwemvura paminiti i12CC.
