Hydraulic balance valve kuvaka muchina zvikamu CBCA-LBN

Nheyo yekushanda uye basa revhavha yekuyamura

1, iyo vharafu yekuyamura inogara ichimanikidza kufashukira maitiro: muhuwandu hwepombi throttling regulation system, iyo yehuwandu pombi inopa inogara ichiyerera. Kana iyo system pressure ichiwedzera, kuyerera kudiwa kunoderera. Panguva ino, vharuvhu yekuyamura inovhurwa, kuitira kuti kuyerera kwakawandisa kudzoke kumashure kwetangi, kuve nechokwadi kuti iyo yekuyamura valve inlet pressure, ndiko kuti, pombi yekubuda kwepombi inogara iripo (gomba revhavha rinowanzovhurwa nekudzvinyirira kushanduka) .

2, kuchengetedzwa kwekuchengetedza: Kana iyo system iri kushanda zvakajairika, valve yakavharwa. Chete kana mutoro unopfuura muganhu wakatarwa (system pressure inodarika iyo set pressure), iyo yakawandisa inovhurwa kuti iwedzere kudzivirira, kuitira kuti iyo system yekumanikidza haichawedzerwe (kazhinji iyo set pressure yevhavha yekuyamura iri 10% kusvika 20% yakakwirira kudarika yakanyanya kushanda kudzvinyirira kwehurongwa).

3, sevharuvhu rekuburitsa rinoshandiswa seremote pressure regulator:

A high and low pressure multistage control valve inoshandiswa sevhavha yekutevedzana kuti ibudise kumashure kumanikidzika (tambo pakudzoka kwemafuta rekiti).

Ivhavha yekuyamura mutyairi ine zvikamu zviviri: vharuvhu hombe uye vharafu yekutyaira. Mavharuvhu ekutyaira akafanana neakananga-anoita mavharuvhu ekuyamura, asi anowanzo ari cone vharafu (kana bhora vharafu) akaumbwa zvigaro zvimiro. Ivhavha huru inogona kukamurwa kuva imwe concentric chimiro, maviri concentric chimiro uye matatu concentric chimiro.

Pavhavha huru, pane musiyano wakajeka kubva kune mamwe mavharuvhu ekuyamura. Ivhavha huru yekuyamura yemucheri ane basa rekusimbisa ichave inopfuura imwe pilot pipe. Dambudziko revhavha huru yekuyamura kazhinji nderekuti chitubu chemukati chakatyoka kana kutadza, iyo yevhavha yepakati yakapfekwa, uye kushanda kwese hakuna simba uye kudzvanywa hakugone kusimbiswa.
