The vharafu shutoff: zvinhu uye kukura

Vhara-kure vharafu rinoshandiswa nenzira dzakasiyana-siyana nyere, uyewo kuerera-kuburikidza zvivako, anoridza basa rimwe nokukiya mudziyo. Kana kurishandisa, unogona kuvhiya zhinji: kubviswa kubva hita network, Somuenzaniso, uyewo kubviswa yechipiri kupisa kutapurirana, kana vharuvhu kuvharwa. Vhara-kure vharafu zvingabudirira kushandiswa mune pre-BALANCInG hurongwa. Izvi mhando chisimbiso chinoshanda zviviri nzvimbo zvakafanana zvinokosha - rakazaruka kana kuti kuvharwa. Setsika, zviri akatasva hunyambiri uye zvido zvevanhu mitsetse, apo kushanda kwezvakatipoteredza runodzorwa ndiro. Shutoff vharafu wanamatira nomuzongoza kazhinji nokuda munhu flanged kubatana kana nomoto.

Izvi mhando mavharuvhu inowanzobvunzwa yakarumbidza dzinofunga mikuru, iro muitiro rokutakura inopisa uye kutonhora mvura akaronga kuti unyanzvi zvinangwa, mhepo uye mvura mhute. Not varumbidzwa kushandisa kuti throttling sezvo hasha mvura uye magasi aigona kuva zvaparadza vharuvhu.

Vhara-kure vharafu mvuto akasiyana zvishoma zvekuvaka, akafanirwa kune yokuti mvuto hauna akagadzirirwa kuramba ichishanda. mavharuvhu kwakadaro zvinoda kugara rokuongorora uye yokudzivisa yokuzvigadzirisa. Mvuto mavharuvhu vakakwanisa zvakanaka nekusimba mukati hurongwa zvaisanganisira dzakatakura chepfu zvinwiwa, Vacuum uye hasha vezvenhau. Zvakakosha kunzwisisa kuti ari chiitiko mvuto kukundikana, zvingangoita kuti kukonzera depressurization ari kuchinja rwekuita kwezvakatipoteredza. Kana paiva vhinza ane hasha kana chepfu zvemagetsi, kunogona kuva nengozi kuti zvipenyu nezvakazvipoteredza mamiriro imwe nzvimbo.

Vhara-kure vharafu diaphragm peristaltic mhando kana vane zvimwe pezvatinokanganisa. Panyaya iyi, panowanikwa kusingafadzi mamiriro ezvinhu anogona kuva nokuda kukundikana rabha hosipaipi kana membrane. Kana ukashandisa yemagetsi, panguva oparesheni yose nguva kunodiwa kuti akuteerere ezvinhu ake.

Shutoff vharafu flange wanamatira mugaba kana rukoronga kuburikidza flanges. Sezvo ayo zvakwakanakira zvinosanganisira mukana vakawanda chokugadza kubviswa pamusoro mutopota, rakaisvonaka chisimbiso junctions, nyore tightening, kuti applicability kune zvakawanda nematambudziko, simba zvikuru. Sezvataona kutadza tightness kurasikirwa nokuda mukana kusunungura, hombe kukura uye yakawanda uremu.

Valve yokupeta akabatanidza nezvezvandaifanira zvizere mvura chokubuda blockage. Vari yemanyorero kushandiswa apo zvaida rakavharwa-kure tightness uye rakavimbika kushanda.

The vharafu inofanira kuiswa iri nyore nzvimbo, iyo ichava inokwanisika zvakakwana basa. Zvivanakire, aibuda mwero yokudzora kupisa kuchinjirwa svikiro kana coolant vharuvhu vakapakata rinokosha nechinyoreso.

Kuwedzera kune izvi mhando maindasitiri muti mavharuvhu zvinowanzoshandiswa mvura Heaters, kudziyisa uye kutonhodza enyika.
