Nhanganyaya kune mashandisirwo, huru zvinhu uye zvimiro zvechimiro chewafer dual plate check valve

Waferndiro mbiricheki vharafuinoreva vharuvhu inongovhura nekuvhara vharafu nekuvimba nekuyerera kwepakati pachayo kudzivirira kuyerera kwepakati, inozivikanwawo secheck valve, one-way valve, reverse flow valve uye back pressure valve. Waferndiro mbiricheki vharafuivharuvhu yeotomatiki iyo basa guru nderokudzivirira kuyerera kwepakati, kudzivirira kutenderera kwepombi uye mota yekutyaira, uye kuburitsa svikiro mumudziyo. Waferndiro mbiricheki mavharuvhu anogona zvakare kushandiswa pamitsetse inopa ebetsero masisitimu uko kudzvanywa kunogona kukwira pamusoro pesimba rehurongwa.

1. Wafer mhando mbiri ndiro cheki vharafu application:

Waferndiro mbiricheki vharafuinoiswa muhurongwa hwepipeline, uye basa rayo guru nderokudzivirira kudzoka kwepakati. The waferndiro mbiricheki vharafuivharuvhu otomatiki inovhurwa nekuvharwa zvichienderana nekudzvanywa kwepakati. Wafer-mhandondiro mbiricheki vharafuinokodzera zita rekumanikidza PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; zita dhayamita DN15 ~ 1200mm, NPS1/2 ~ 48; kushanda tembiricha -196 ~ 540 ℃ pamapaipi akasiyana-siyana, anoshandiswa kudzivirira kuyerera kwepakati. Nekusarudza zvinhu zvakasiyana, inogona kuiswa kune akasiyana midhiya senge mvura, chiutsi, mafuta, nitric acid, acetic acid, yakasimba oxidizing yepakati uye uric acid.

2. Chinhu chikuru chemuchekandiro mbiricheki vharafu:

Kune kabhoni simbi, yakaderera tembiricha simbi, dual phase simbi (F51/F55), titanium alloy, aruminiyamu bhuronzi, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum simbi, Monel (400/500), 20# chiwanikwa, Hastelloy nezvimwe zvinhu zvesimbi.

3. Mamiriro ezvinhu endiro mbiricheki vharafu:

1. Kureba kwechimiro ipfupi, uye kureba kwayo kwechimiro ingori 1/4 ~ 1/8 yechinyakare flanged.swingcheki vharafu.

2. Saizi diki uye huremu huremu, huremu hwayo hungori 1/4 ~ 1/20 yeyakajairwa flanged.swingcheki vharafu.

3. Ivhavha disc inovhara nokukurumidza uye nyundo yemvura inodzvinyirira iduku

4. Mapaipi ese ari maviri akatwasuka kana vertical pombi anogona kushandiswa, nyore kuisa

5. Mugero wekuyerera unotsvedzerera uye kudzivirira kwemvura kudiki

6. Sensitive action uye yakanaka yekuisa chisimbiso kuita

7. Ivhavha disc kufamba ipfupi uye kuvhara kwekuita simba kuduku

8. Chimiro chese chiri nyore uye chakabatana, uye chimiro chakanaka

9. Hupenyu hurefu hwebasa uye kushanda kwakavimbika

Chechina, zvikanganiso zvakajairika zvendiro mbiricheki valve ndeiyi:

1. Ivhavha disc yakaputsika

Kumanikidzwa kwepakati pamberi uye shure kwendiro mbiricheki vharafuiri muhutano hwepedyo uye mutual "saw". Ivhavha disc inowanzorohwa nechigaro chevhavha, uye diski yevhavha yakagadzirwa nezvimwe zvinhu zvinoputika (zvakadai sesimbi yakakandwa, ndarira, nezvimwewo) inorohwa. akatyoka.

Nzira yekudzivirira ndeye kushandisa andiro mbiricheki vharafu ine dhisiki sechinhu chinonzi ductile.

2. Medium backflow

Nzvimbo yekuisa chisimbiso yakakuvadzwa; tsvina inobatwa.

Nekugadzirisa nzvimbo yekuisa chisimbiso uye kuchenesa tsvina, backflow inogona kudzivirirwa.
