Chii chinonzi Check Valve: Gwaro Rekupedzisira reRudzi neStandard.

Tarisa Vharuvhu Pfupiso

Vharuvhu yekutarisa ivharuvhu inongoerekana yashandiswa inoshandisa kumanikidzwa kwemvura uye huremu hwediski kudzivirira kuyerera kwemvura. Inozivikanwawo sevharuvhu isingadzokeri, nzira imwe chete, reflux, kana isolation, basa rayo guru nderekuona kuyerera kwemvura nenzira imwe chete kudzivirira masisitimu emapaipi kubva mukukuvadzwa kwekudzokera shure.

Mashandiro Emavharuvhu Ekutarisa

Kuyerera mberi: Kumanikidzwa kwemvura kunosimudza dhisiki, zvichiita kuti ipfuure.

Kuyerera kwekudzoka shure: Dhisiki rinovhara kuburikidza nekumanikidzwa kwegiravhiti/mvura, richivhara media.

Zvikamu Zvikuru zveCheck Valve

Zvikamu zvakakosha zvinosanganisira:

Muviri weVharuvhu: Mapaipi anobatanidza ekunze

Dhisiki: Chikamu chefoni chinogonesa kudzora kuyerera

Chigaro: Inoumba pamusoro pechisimbiso nedhisiki

Chitubu: Inomanikidza kuvharwa kwedhisiki (mumhando dzinobatsirwa nechirimo)

Tarisa Chiratidzo cheVharuvhu muPID Diagram

Kunzwisisa Chiratidzo cheCheck Valve

1.Denderedzwa: Inomiririra muviri wevharuvhu.

2.Museve kana Mutsetse weDiagonal: Inoratidza divi rekuyerera kwemvura. Izvi zvakakosha pakuiswa, sezvo zvichiita kuti vharuvhu iiswe nemazvo mukati mesystem.

3.Mamwe Mashoko: Dzimwe nguva, mamwe mashoko kana mazita anogona kuperekedza chiratidzo ichi kuti chipe rumwe ruzivo, senge saizi yevharuvhu, zvinhu, kana chiyero chekumanikidzwa.

Tarisa Maitiro Ekugadzira Mavharuvhu

Kutevedzera mitemo kunosanganisira mitemo yenyika, yeindasitiri, uye yepasi rose yezvinhu zvekuvaka, mashandiro, uye kuiswa:

Mabhenefiti ekutarisa vharuvhu

Mabhenefiti Ekugadzira & Kushanda

Kuzvishandira wega: Hapana simba rekunze rinodiwa (giravhiti/chitubu/rinofambiswa nemvura)

Mhinduro nekukurumidza: Kuvharwa kwemasekonzi ≤0.05 (mavharuvhu evacuum) kunodzivirira kusvibiswa kwemvura inoyerera

Magadzirirwo akasiyana-siyana:

• Rudzi rwechikwidzo: Chisimbiso chepamusoro chemidziyo yakachena ine P yakawanda
• Rudzi rwekutenderera: Kudzivirira kwakaderera kwemapombi ane zvidimbu
• Dual-disc: Yakabatana kune masisitimu ane nzvimbo shoma

Kushanda & Kuchengetedzeka

• Inovhara kufamba kwemhepo ine radioactive/corrosive (zvimiti zvenyukireya/makemikari)
