Vharuvhu yekutarisa yeMaindasitiri Yemhando Yepamusoro China fekitori mutengesi Mugadziri
Chii chinonzi check valve?
Vharuvhu yekuchekesa rudzi rwevharuvhu ine chinangwa chekutungamira kumwe chete, zvakare sevharuvhu dzisingadzorerwe.
Vharuvhu Yekutarisaivharuvhu iri nyore uye yakavimbika ine bhora rakatenderera sechikamu chega chinofamba chinodzivirira kuyerera kwemvura kumashure. Nekuda kwekugadzirwa kwayo kuri nyore uye kusina kugadzirisa, vharuvhu inowanzo tsanangurwa uye inoshandiswa munzvimbo dzekusimudza mvura yetsvina dzinonyudzwa mumvura. Chigaro chevharuvhu chakazara chakagadzirwa zvakasiyana zvichibvumira bhora kugara zvakasimba pasina kupinda muchigaro chevharuvhu. Pakushandisa vharuvhu ye vacuum kana yekudzivirira mafashamo, bhora "rinoyangarara" pane "kunyura" rinoshandiswa.
mavharuvhu ekuongororaine bhora rakagara pachigaro, chine buri rimwe chete rinopinda nepakati. Rinoshanda nebhora rinofamba richikwira nekudzika mukati mevharuvhu. Chigaro chacho chakagadzirwa kuti chikwane bhora, uye kamuri racho rakaumbwa nechimiro chekona kuti ritungamire bhora muchigaro kuti rivhare uye rimise kuyerera kwerinodzokera shure. Bhora racho rine dhayamita yakakura zvishoma kupfuura yeburi rinopinda nepakati (chigaro). Kana kumanikidzwa kuri kuseri kwechigaro kuchipfuura kuri pamusoro pebhora, mvura inobvumirwa kuyerera nepakati pevharuvhu. Asi kana kumanikidzwa kuri pamusoro pebhora kuchipfuura kumanikidzwa kuri pasi pechigaro, bhora rinodzokera kunogara muchigaro, richigadzira chisimbiso chinodzivirira kudzokera shure. Bhora rinofamba richikwira nekudzika mukati mevharuvhu zvichienderana nekuyerera uye rinovhara pachigaro chakagadziriswa kana pasina kuyerera kana kuyerera kwerinodzokera shure kunoitika uye rinovhara pachigaro kuti rimise kuyerera kwerinodzokera shure.
Zvinhu zvikuru zve check valve
Hunhu uye mabhenefiti eVharuvhu Yekutarisa
- vhara kuyerera kwemvura kunotevera,dhizaini isina kugadziriswa, suitbale yezviteshi zvekusimudza mvura yakasviba zvinonyudzwa mumvura.
- *Chigaro chevharuvhu chakazara chakagadzirwa zvakasiyana-siyana zvichiita kuti bhora rigare zvakasimba risingapindi muvharuvhu.
- *NortechVharuvhu Yekutarisazvinozvichenesa zvega, sezvo bhora richitenderera panguva yekushanda izvo zvinobvisa njodzi yekuti tsvina inamire pabhora.
- *Bhora rakazara uye rakatsetseka rinovimbisa kuyerera kwakazara nekurasikirwa nekumanikidzwa kwakaderera uye rinobvisa njodzi yekuiswa pasi kunogona kudzivirira kuvharika kwakasimba. Bhora rakajairika rakagadzirwa nesimbi ine rabha yeNBR, uye kuomarara kwerabha kwakagadziridzwa kudzivirira bhora kuti risabatirire pachigaro. Mabhora epolyurethane akakodzera abrasive media uye kana mabhora akasiyana achidikanwa kudzivirira ruzha nehammer yemvura.

Kuratidzwa Kwechigadzirwa: vharuvhu yekutarisa
Mashandisirwo evharuvhu yekutarisa
Rudzi urwu rwevharuvhu yekutarisainoshandiswa zvakanyanya mukushandiswa kwemvura yakasviba, mafekitori emagetsi uye indasitiri yekugadzira zvinhu. Vharuvhu yekutarisa bhora yakakodzera kushandiswa munzvimbo dzakasvibiswa (kusvika 120˚F) sezvo vharuvhu yakaita sebhora inodzivirira kuungana kwetsvina. Kazhinji nzvimbo yekusimudza mvura yakasviba ine vharuvhu yekutarisa bhora kudzivirira kuyerera kwemvura. Inoshandiswawo zvakanyanya munzvimbo dzekupomba dzisingawanzo svikirwi.
