Chii chinodzvinyirira chepasi-pressure valve, pressure range uye grade classification ye low-pressure valve

Valve inhengo yekudzora mune fluid transmission system. Icho chigadzirwa chemagetsi chinodzora kuyerera kwemvura, kudzvanywa uye kuyerera kwekutungamira nekushandura saizi yenzvimbo yekuyerera kwayo. Kune marudzi akawanda emavharuvhu, uye low-pressure valve imhando inoshandiswa kakawanda. Chii chinonzi kumanikidzwa kwevhavha yepasi-pressure? Iyi nyaya inounza kudzvanywa kwemhando uye giredhi kupatsanurwa kwemavharuvhu epasi-kumanikidza! Tariro kukubatsira!

1¡¢ Chii chinodzvinyirira chevhavha yakaderera

Kazhinji, mapoinzi ekuparadzanisa ari 1.6Mpa uye 10.0MPa. Iyo yakaderera-kudzvanywa pombi ndiyo ine dhizaini yedhizaini isingasviki kana kuenzana ne1.6Mpa, iyo yepakati-kumanikidza pombi ndiyo ine dhizaini yedhizaini yakakura kupfuura 1.6Mpa uye isingasviki kana kuenzana ne10.0MPa, uye pombi yekumanikidza yakanyanya. ndiyo ine dhizaini yekumanikidza yakakura kupfuura kana yakaenzana ne10.0MPa. Pombi yepressure inoreva mapaipi ese ane kumanikidza kwemukati kana kunze, zvisinei nepakati mupombi.

Mamwe mavharuvhu anomanikidza anogona zvakare kusiyaniswa neizvi

1. Low pressure pombi engineering pressure

2. Kudzvinyirira kwepakati pepipeline yepakati inoshanda ndeye 1.6-6.4mpa

3. High pressure pipeline engineering pressure> 10MPa

Ultra high pressure valve ———– nominal pressure PN ¡Ý 100MPa;

High pressure valve ———– nominal pressure PN10 0 ~ 80.0MPa;

MP vharafu ———– nominal pressure pN2 5 ~ 6.4MPa;

Low pressure valve ———– nominal pressure PN ¡Ü 1.5MPa

2¡¢ Kudzvanywa kwehuwandu uye giredhi kupatsanurwa kwe low pressure valve

1. Vacuum valve: valve ine pressure

2. Low pressure valve: vharafu ine zita rekumanikidza PN ¡Ü 1.6Mpa (kusanganisira simbi yesimbi ine PN ¡Ü 1.6Mpa)

3. Medium pressure valve: nominal pressure pN2 5-6.4mpa valve.

4. High pressure valve: nominal pressure PN10 0-80.0mpa valve.

5. Ultra high pressure valve: valve ine zita rekumanikidza PN ¡Ý 100.0mpa.
