Nhanganyaya yekushandiswa, chinhu chikuru uye maitiro ezvimiro zvewaferi cheki chevhavha

Tarisa vharafu zvinoreva vharafu rinongovhura nekuvhara vhara vhara nekuvimba nekuyerera kwepakati pachayo kudzivirira kuyerera kwepakati, inozivikanwawo se.cheki vharafu, imwe-nzira vharafu, reverse flow valve uye back pressure valve. Thecheki vharafuivharuvhu yeotomatiki iyo basa guru nderokudzivirira kuyerera kwepakati, reverse kutenderera kwepombi uye mota yekutyaira, uye kubuda kwepakati mumudziyo. Cheki mavharuvhu anogona zvakare kushandiswa pamitsetse inopa ebetsero masisitimu uko kudzvanywa kunogona kukwira pamusoro pesimba rehurongwa.

1.Tanoshandisa chevhavha yekutarisa:

Thecheki vharafu inoiswa muhurongwa hwepipeline, uye basa rayo guru nderokudzivirira kudzoka kwepakati. Thecheki vharafuivharuvhu otomatiki inovhurwa nekuvharwa zvichienderana nekudzvanywa kwepakati.Wafer check valve inokodzera zita rekumanikidza PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; zita dhayamita DN15 ~ 1200mm, NPS1/2 ~ 48; Medium backflow. Nekusarudza zvinhu zvakasiyana, inogona kuiswa kune akasiyana midhiya senge mvura, chiutsi, mafuta, nitric acid, acetic acid, yakasimba oxidizing yepakati uye uric acid.

2.Tiye main material of thewafer check valve:

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 ewafer check valve:

A. Kureba kwechimiro kupfupi, uye kureba kwayo kunongova 1/4 ~ 1/8 yeiyo yechinyakare flange cheki vharafu.

B. Saizi diki uye huremu huremu, uremu hwayo hungori 1/4 ~ 1/20 yechinyakare flange cheki valve

C. Ivhavha disc inovhara nekukurumidza uye nyundo yemvura inomanikidza idiki

D. Mapaipi ese akachinjika kana mapombi akatwasuka anogona kushandiswa, nyore kuisa

E. Iyo yekuyerera mugero yakatsetseka uye inodzivirira yemvura idiki

F. Sensitive chiito uye yakanaka yekuisa chisimbiso kuita

G. Iyo valve disc yekufamba ipfupi uye yekuvhara simba rekuita idiki

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

I. Hupenyu hurefu hwebasa uye kushanda kwakavimbika

4.Tizvo zvinowanzoitika zvikanganiso zvecheki valve ndezvi:

A. Ivhavha disc yakaputsika

Kudzvinyirirwa kwepakati pamberi uye shure kwevhavha yekuongorora iri mumamiriro ekuswedera pedyo nekuenzanisa uye "saw" mutual. Ivhavha disc inowanzorohwa nechigaro chevhavha, uye diski yevhavha yakagadzirwa nezvimwe zvinhu zvinoputika (zvakadai sesimbi yakakandwa, ndarira, nezvimwewo) yakaputsika. Nzira yekudzivirira ndeyokushandisa cheki valve ine diski se ductile zvinhu.

B. Medium backflow

Nzvimbo yekuisa chisimbiso yakakuvadzwa; tsvina inobatwa. Nekugadzirisa nzvimbo yekuisa chisimbiso uye kuchenesa tsvina, backflow inogona kudzivirirwa.
