Kuiswa kwegedhi mavharuvhu
Gedhi valve, inozivikanwawo sevhavha yegedhi, iko kushandiswa kwegedhi kudzora kuvhura uye kuvhara kwevhavha, nekushandura chikamu chemuchinjikwa kugadzirisa kuyerera kwepombi uye kuvhura nekuvhara pombi.Mavharuvhu egedhi anonyanya kushandiswa papombi yekuzaruka kwakazara kana kuvharika kushanda kwemvura yepakati.Kuiswa kwegedhi revhavha kazhinji hakuna nzira inodiwa, asi haigone kuisirwa kumusoro pasi.
Kuiswa kweglobe valve
Globe valve ndiko kushandiswa kwe disc kudzora kuvhura uye kuvhara kwevhavha.Nekushandura gap pakati pe disc uye chigaro, ndiko kuti, kushandura saizi yechikamu chechiteshi kugadzirisa kuyerera kwepakati kana kugura nzira yepakati.Kuchenjerera kunofanirwa kubhadharwa kuyerera nzira kana uchiisa mavharuvhu eglobhu.
Nheyo inotevedzwa pakuisa vheji yeglobe ndeyokuti mvura iri mupombi inopfuura nepagomba revharuvhu kubva pasi kuenda kumusoro, rinowanzozivikanwa se "pasi kusvika kumusoro", uye haribvumidzwe kuiswa kumashure.

Kuiswa kwekudzvinyirira kuderedza vharafu
Pressure yekudzikisa vharafu inogadziriswa kuti ideredze inlet kudzvanywa kune inodiwa yekubuda kudzvanywa, uye kuvimba nesimba repakati pachayo, kuitira kuti iyo yekubuda shinikizo ichengetedze yakagadzikana valve.
Kubva pakuona kwemvura mechanics, kudzvinyirira kuderedza valve inzvimbo yekudzivirira inogona kushandura throttle element, kureva, nekushandura nzvimbo ye throttle, iyo inoyerera uye mvura kinetic simba shanduko, zvichiita kuti kurasikirwa kwakasiyana kwakasiyana, kuitira kuti zvibudirire. chinangwa che decompression.Wobva wavimba nekudzora uye hurongwa hwekugadzirisa hurongwa, kuitira kuti vharafu yekumanikidza kushanduka uye chitubu simba rekuenzanisa, kuitira kuti vharafu kumanikidzwa mune imwe siyana kukanganisa kuchengetedza nguva dzose.
1. Boka rekudzikisa vharafu rakaiswa vertically rinowanzorongedzwa pamadziro paurefu hwakakodzera kubva pasi;Horizontally mounted pressure relief valve seti dzinowanzoiswa pachikuva chekushanda chisingaperi.
2. Kushandiswa kwesimbi zvakateerana mumavharuvhu maviri ekudzora (anowanzo shandiswa kuvharuvhu yeglobe) kunze kwemadziro, achigadzira bracket, bypass pombi inonamirawo pabhuraketi, kuenzanisa uye kurongeka.
3. Ivhavha yekuderedza kumanikidzika inofanira kuiswa vertically mupombi yakakomberedzwa, isina kurereka, museve uri pamutumbi wevharuvhu unofanira kunongedza kudivi rekuyerera kwepakati, kwete kuiswa.
4. Stop valve uye high and low pressure pressure gauge inofanira kuiswa kumativi ose maviri kuti ione kushanduka kwekumanikidza mberi uye shure kwevhavha.Iyo dhayamita yepombi mushure mekumanikidza kuderedza vharafu inofanira kunge iri 2#-3# yakakura kupfuura iyo inopinza pombi dhayamita pamberi pevharuvhu, uye isa pombi yekunzvenga kuitira kugadzirisa.
5. Iyo yekumanikidza yakaenzana pombi yefirimu kudzvinyirira kuderedza valve inofanira kubatanidzwa kune yakaderera-kumanikidza pombi.Chengetedzo vharafu inofanirwa kuisirwa pasi pekumanikidza pombi kuti ive nechokwadi chekushanda kwakachengeteka kwehurongwa.
6. Kana yakashandiswa pakuderedzwa kwemhepo, pombi yemvura inofanira kuiswa.Kune masisitimu epombi anoda dhigirii repamusoro rekucheneswa, sefa inofanirwa kuiswa pamberi pevharuvhu yekudzikisa.
7. Mushure mokuiswa kweboka rekuderedza kudzvinyirira kwevhavha, kuedza kudzvinyirira, kushambidza uye kugadzirisa kunofanira kuitwa pavhavha yekuderedza kudzvinyirira uye kuvhara kwevhavha maererano nezvinodiwa zvekugadzira, uye chiratidzo chinogadziriswa chinofanira kuitwa.
Paunenge uchikwesha vharafu yekudzikisira, vhara iyo inlet vharafu yevhavha yekudzikisira uye uvhure vharafu yekutsvaira.
