Vharuvhu yekutarisa bhora yeNBR yemhando yepamusoro yeIndasitiri China fekitori mutengesi Mugadziri
Chii chinonzi NBR ball check valve?
AVharuvhu yekutarisa bhora reNBRivharuvhu 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.
Vharuvhu yekutarisa bhora reNBRine bhora rinogara pachigaro, rine buri rimwe chete rinopinda nepakati. Rinoshanda nebhora rinofamba richikwira nekudzika mukati mevharuvhu. Chigaro chacho chakagadzirwa kuti chikwane bhora, uye kamuri racho rakaumbwa nekona 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 pachigaro, 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. mavharuvhu ekutarisa ane bhora rakaiswa muBuna-N seyakajairwa uye ane mabhora ephenolic anodzivirira ngura ekushandisa abrasive media.

- *Chigaro chevharuvhu chakazara chakagadzirwa zvakasiyana-siyana zvichiita kuti bhora rigare zvakasimba risingapindi muvharuvhu.
- *NortechVharuvhu Yekutarisa Bhorazvinozvichenesa 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: NBR bhora rekutarisa vharuvhu
Mashandisirwo evharuvhu yekutarisa bhora reNBR
Rudzi urwu rweVharuvhu yekutarisa bhora reNBRinoshandiswa 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. Inoshandiswawo zvakanyanya munzvimbo dzekupomba dzisingawanzo shandiswa, sezvo dzichida kugadziriswa kushoma, kazhinji kana bhora richiita ruzha rwunokonzerwa nekusakwana kwepombi kana sando yemvura.
