Plug mavharuvhu

A Plug Valve ikota-turn rotational motion Valve inoshandisa puragi yakaderedzwa kana cylindrical kumira kana kutanga kuyerera. Munzvimbo yakavhurika, iyo plug-passage iri mumutsara mumwe neinopinza uye yekubuda zviteshi zvemuviri weValve. Kana iyo plug 90 ° ikatenderedzwa kubva panzvimbo yakavhurika, chikamu chakasimba cheplug chinovhara chiteshi uye chinomira kuyerera. Mavharuvhu eplug akafanana neBhora mavharuvhu ari kushanda.

Mhando dzePlug valves

Mavharuvhu epuragi anowanikwa mune isina mafuta kana mafuta dhizaini uye ine akati wandei masitaera ekuvhurwa kwechiteshi. Chiteshi chiri mune tapered plug chinowanzoita rectangular, asi ivo vanowanikwawo nemaround ports uye madhaimani ports.

Plug valves inowanikwawo ne cylindrical plugs. Iwo ma cylindrical plugs anovimbisa kuvhurwa kwechiteshi kwakakura kuenzana kana kuhombe pane nzvimbo yekuyerera kwepombi.

Lubricated Plug mavharuvhu anopiwa ane mhango pakati pamwe ipapo axis. Iyi mhango yakavharwa kuzasi uye yakaiswa sealant-injection inokodzera kumusoro. Iyo sealant inopinzwa mugomba, uye Cheki Valve pazasi pejekiseni yakakodzera inodzivirira sealant kuyerera ichidzokera kumashure. Iyo lubricant mukuita inova chikamu chechimiro cheValve, sezvo ichipa inochinjika uye inovandudzwa chigaro.

Nonlubricated Plug mavharuvhu ane elastomeric body liner kana sleeve, inoiswa mumhango yemuviri. Iyo plug yakakwenenzverwa uye yakakwenenzverwa inoita seweji uye inodzvanya ruoko pamuviri. Saka, iyo isiri simbi sleeve inoderedza kupokana pakati peplug nemuviri.

Plug valve Disk

Rectangular port plugs ndiyo yakajairika port shape. Iyo rectangular port inomiririra 70 kusvika 100 muzana yenzvimbo yemukati pombi.

Round port plugs ane denderedzwa rakavhurika kuburikidza neplug. Kana kuvhura kwechiteshi kwakafanana saizi kana yakakura kupfuura mukati medhayamita yepombi, chiteshi chakazara chinorehwa. Kana kuvhura kuri kudiki pane dhayamita yemukati yepombi, mureza wakatenderera chiteshi chinorehwa.

Diamond port plug ine chiteshi chakaita sedhaimani kuburikidza neplug uye iwo ari venturi anorambidzwa kuyerera marudzi. Iyi dhizaini inokodzera throttling service.

Yakajairika mashandisirwo ePlug mavharuvhu

A Plug Valve inogona kushandiswa mumasevhisi akawanda akasiyana emvura uye vanoita zvakanaka mukushandisa slurry. Aya anotevera mamwe akajairika maapplication ePlug mavharuvhu:

• Mhepo, gasi, uye masevhisi emhute
• Natural gasi pombi masisitimu
• Oiri pombi masisitimu
• Vacuum kune yakakwirira-kumanikidza maapplication

Zvakanakira uye Zvakaipa zvePlug mavharuvhu

Zvakanakira:

• Quick quarter turn on-off operation
• Minimum resistance to flow
• Diki muhukuru kupfuura mamwe mavharuvhu mazhinji

Zvakaipa:

• Inoda simba guru kuti riite, nekuda kwekukweshana kukuru.
• NPS 4 uye mavharuvhu makuru anoda kushandiswa kweactuator.
• Yakaderedzwa chiteshi, nekuda kwetapered plug.
