Gedhi Mavharuvhu Vagadziri

Gedhi valve igedhi rekuvhura nekuvhara zvikamu. Mafambiro egedhi ari perpendicular to the fluid direction. Ivhavha yegedhi inogona kungovhurwa zvakakwana uye yakavharwa zvakakwana, uye haigoni kugadziriswa uye kuvharwa. Ivhavha yegedhi yakavharwa nekusangana pakati pechigaro chevhavha uye gedhi. Kazhinji, nzvimbo yekuisa chisimbiso ichave yakafukidzwa nezvinhu zvesimbi kuti iwedzere kupikisa kupfeka, zvakadai sekuvhara 1Cr13, stl6, simbi isina tsvina, etc. Kune yakasimba gedhi valve uye elastic gedhi valve. Zvinoenderana nemusiyano wevhavha yegedhi, vharanda regedhi rakakamurwa kuita rigid gedhi valve uye elastic gedhi valve.
Kana gedhi revhavha rakavharwa, nzvimbo yekuisa chisimbiso inogona kuiswa chisimbiso chete nekumanikidza kwepakati, ndiko kuti, nzvimbo yekuisa chisimbiso yevhavhavha yegedhi inotsikirirwa pakatarisana nechigaro chevhavha kune rumwe rutivi nekumanikidza kwepakati kuti kuve nechokwadi chekuiswa chisimbiso. pamusoro, iko kuzvisimbisa. Mazhinji mavharuvhu emagedhi anomanikidzwa kuiswa chisimbiso, ndiko kuti, kana vharuvhu yakavharwa, gedhi rinofanira kumanikidzirwa kuchigaro chevhavha nechisimba chekunze kuti ive nechokwadi chekusimba kwechisimbiso chepamusoro.

Movement mode: gedhi regedhi revhavha rinofamba zvakatevedzana netsinde yevharuvhu, inozivikanwawo serinokwira stem gedhi vharafu. Kazhinji, tsvimbo yekusimudza inopiwa ne trapezoidal thread. Kuburikidza nenati iri pamusoro pevharuvhu uye girovha yegirovha pamutumbi wevharuvhu, iyo inotenderera inoshandurwa kuita mutsara wekufamba, ndiko kuti, torque yekushanda inoshandurwa kuita basa rekushanda. Kana iyo valve yakavhurwa, kana kusimudza kureba kwegondohwe kwakaenzana ne1: 1 nguva dzevhavhavhavha, chiteshi chemvura hachina kuvharwa zvachose, asi chinzvimbo ichi hachigone kuongororwa panguva yekushanda. Mukushandiswa chaiko, nhongonya yehunde yevharuvhu inotorwa sechiratidzo, ndiko kuti, nzvimbo iyo dzinde revharuvhu risingagoni kuvhurwa inotorwa senzvimbo yayo yakazara yakazaruka. Kuti titarise chiitiko chekuvhara chinokonzerwa nekushanduka kwekushisa, inowanzodzoserwa kumashure 1 / 2-1 denderedzwa panzvimbo yepamusoro sechinzvimbo chekuvhura zvizere valve. Nokudaro, nzvimbo yakazaruka yevhavha inotarirwa maererano nenzvimbo ye RAM (kureva sitiroko). Mamwe mavharuvhu ane hunde revharuvhu akaiswa pagondohwe, uye kutenderera kwevhiri reruoko kunofambisa dzinde revharuvhu kuti ritenderere kusimudza gondohwe. Iri vharuvhu inodaidzwa kuti vheruvha yegedhi rinotenderera kana kuti Non rising stem gedhi vharuvhu.

Mavharuvhu egedhi akakamurwa kuita wedge mhando uye parallel mhando zvichienderana nechimiro chegedhi. Wedge ram ine zvimiro zvitatu: gondohwe rimwe chete, gondohwe kaviri uye elastic gondohwe.

Mavharuvhu egedhi akakamurwa kuita flat gedhi mavharuvhu uye banga magedhi mavharuvhu maererano akasiyana zvimiro mhando.

Kushanda musimboti wegwaro regedhi remaoko: tenderedza vhiri reruoko kuvhura nekuvhara ndiro yevharuvhu yakabatana netsvimbo yevharuvhu nekufambira mberi nekudzosa tambo dzevhiri reruoko nerutanda rwevharuvhu.

Zvinoenderana nekugadzika kwegomba / main body zvinhu, mavharuvhu emagedhi anogona kukamurwa kuita:

Metal mavharuvhu: akadai kabhoni simbi mavharuvhu, alloy simbi mavharuvhu, Stainless simbi mavharuvhu, cast simbi mavharuvhu, titanium alloy mavharuvhu, Monel mavharuvhu, mhangura alloy mavharuvhu, lead alloy mavharuvhu, etc.

Metal body lined mavharuvhu: akadai rabha lined mavharuvhu, fluorine lined mavharuvhu, lead lined mavharuvhu, epurasitiki lined mavharuvhu uye enamel lined mavharuvhu.

Non esimbi mavharuvhu: akadai zvedongo mavharuvhu, girazi mavharuvhu uye epurasitiki mavharuvhu.

Advantage

1. Kuramba kuyerera kuduku. Iyo yepakati chiteshi mukati memuviri wevharuvhu yakatwasuka, yepakati inoyerera mumutsara wakatwasuka, uye kuyerera kwekudzivirira kudiki.

2. Inoponesa basa pakuzarura nekuvhara. Kuenzaniswa nevhavha yekumisa, mafambiro egondohwe ari perpendicular kune yepakati kuyerera nzira ingave yakavhurika kana yakavharwa.

3. Kureba kwepamusoro uye kuvhura kwenguva refu uye nguva yekuvhara. Kuvhura nekuvhara kwegondohwe kwakakura, uye kusimudza kunoitwa kuburikidza ne screw.

4. Sando yemvura haisi nyore kuitika. Chikonzero ndechekuti nguva yekuvhara yakareba.

5. Iyo yepakati inogona kuyerera mune chero nzira kumativi ose maviri, iyo iri nyore kuisa. Mativi ese ari maviri egedhi revhavha chiteshi ane symmetrical.

6. Kureba kwechimiro (kureba pakati pezviso zviviri zvekuguma kweimba) idiki.

7. Chimiro chakareruka, kureba kwemaitiro mapfupi, maitiro akanaka ekugadzira uye hupamhi hwekushandisa.

8. Compact structure, good rigidity of the valve, smooth passage, small flow resistance, Stainless steel and hard alloy for sealing surface, hupenyu hurefu hwebasa, PTFE kurongedza, kuiswa chisimbiso kwakavimbika, chiedza uye kushandura kushanda.

kupfupisa

(1) Ivhavhavha yegedhi ine nzvimbo mbiri dzekuisa chisimbiso, uye kugadzirisa nekugadzira kwakaoma kupfuura valve yekumisa.

(2) Pane kukakavara pakati penzvimbo dzekuisa chisimbiso, uye kupfeka kwakakura. Hazvina kunaka kugadzirisa nzvimbo dzakasakara dzekuvhara

(3) Kukura kwechimiro chevhavhavhavha yakakura, zvichikonzera kureba kwechimiro, hukuru hwakakura uye nzvimbo huru yekuisa. Iyo huru-diameter yegedhi valve inonyanya kurema

(4) Nguva yakareba yevharuvhu yekuvhura nekuvhara

Parallel double gedhi vharafu

Parallel double gedhi vharafu

(5) Imba yakavharwa yevharuvhu inogona kuumbwa, saka iyo yekumanikidza yekumanikidza chimiro kudzivirira kusimuka kusimuka mukati mekamuri yepakati ichapihwa kana zvichidikanwa.
