Mabhero eglobe mavharuvhu, anozivikanwawo semabhero akavharidzirwa eglobe mavharuvhu, akagadzirirwa kugadzira chipingamupinyi chesimbi pakati pemvura yepakati nemhepo neatomatiki hob-welding kuti ive nechokwadi chekuti zero stem leak. Kuenzaniswa neyechinyakare globe valve ine zvinotevera zvakanakira:
1. Bellows globe valve hupenyu hurefu hwebasa, kuderedza nhamba yekuchengetedza, kuderedza kushandiswa kwemari. Rugged bellows seal dhizaini inovimbisa zero stem kuvuza uye inopa kuchengetedza-yemahara mamiriro.
2. Valve kuvhura uye kuvhara torque idiki, kuderedza kushanda nesimba, uye inogona kutyaira chero mhando yedhiraivha mudziyo, nyore kudzora kure.
3. Chitarisiko chakanaka, chiteshi chevhavha chine mutsara wekuyerera, kuderedza kuyerera kupikisa coefficient yevhavha, imhando yepamusoro yezvigadzirwa zvekuchengetedza simba.
4. Chisimbiso chekunze chevhavha chinoshandisa bellows chisimbiso uye graphite, simbi isina tsvina gasket chisimbiso, chisimbiso chakavimbika, kushandiswa kwenguva refu hakugoni kutsiva kuiswa chisimbiso. Mukushandiswa kwemaindasitiri, yakajairika yekumisa vharafu inokonzerwa nekudonha: tembiricha yakanyanya, ine muchetura, inopfuta uye inoputika, radioactive midhiya uye zvichingodaro, kwete chete kusvibiswa kwezvakatipoteredza, asi zvakare kazhinji kukonzeresa kwakakosha kurasikirwa kwemunhu uye pfuma. Iyo bellows stop valve yakachengeteka uye yakagadzikana, uye mazinga epasi rose epamusoro anogamuchirwa zvakanyanya mukugadzira nekugadzira.
Zvakanakira uye mashandisirwo emabhero eglobe valve
Bellows stop valve hapana kuvuza, inoshandiswa mune yakanyanya-njodzi midhiya yakachengeteka.
Mavharuvhu akajairika akavharwa nekurongedza, pakati pehunde uye kurongedza kunotsvedza, zviri nyore kudonhedza pane yakaderera tembiricha (spool).
Bellows globe valve inogona kutambanudzwa uye yakamanikidzwa chisimbiso mabhero panzvimbo yekurongedza chisimbiso, inogona kunyatso kudzivirira kurongedza kurasikirwa kunokonzerwa nekubuda kwekunze. Inowanzo shandiswa kufambisa svikiro rakasimba rinopindika, sevhavha iri pahydrogen system, chero mabhero asina kukuvadzwa, kazhinji hapana kubuda; Uye iyo general globe valve ine kurongedza kuti iname, iri nyore kudonhedza.
Rudzi urwu rwevharuvhu kuvhurika kana kuvhara sitiroko ipfupi, uye ine yakavimbika yekucheka basa, uye nekuda kwekuchinja kwechigaro chevharuvhu kuburikidza nekurova kwe disc kunoenderana zvakananga nehukama, yakakodzera kwazvo kuyerera kwemutemo. Nokudaro, rudzi urwu rwevharuvhu rwakanyatsokodzera kucheka kana kudzora uye kushandisa throttling.
