Ball valve chimiro chakakamurwa kuita inoyangarara mhando uye yakatarwa mhando

Fixed bhora vharafu

Pane groove pasi pevhavha yekugadzirisa bhora revhavha. Pakati pane vharafu yebhora. Pane dzinde revharuvhu kumativi ekumusoro neazasi kugadzirisa bhora kusvika pakati. Kubva kunze, kazhinji, vheji yebhora ine dhisiki yekutsigira nzvimbo pasi pevhavha yebhora ivhavha yebhora yakagadziriswa.

Inoyangarara bhora vharafu

Bhora rinoyangarara nepakati, uye hapana poindi yekutsigira pazasi ivharuvhu yebhora inoyangarara

Iyo yakakura dhayamita yevharuvhu yebhora inoyangarara kazhinji ndeye DN250

Iyo yakakura dhayamita yeyakagadziriswa bhora valve inogona kuva DN1200

Musiyano mukuru pakati peyakagadzika uye inoyangarara bhora mavharuvhu uri mukugadzika kwebhora repakati. Kugadziriswa kunokuvadza chisimbiso zvakasiyana. Mhando yakagadziriswa inowedzera hupenyu hwebasa revhavha yebhora. Ivhavhavha yebhora yakagadziriswa ine hupenyu hurefu hwesevhisi kupfuura iyo inoyangarara bhora vharafu. Bhora rerudzi rwebhora vharafu rinoyangarara richitenderera mugomba, izvo zvinozoita kuti chisimbiso chiyangamire nekunyura. Apo bhora revhavha rinotenderera, pfungwa dzinoshungurudza dzakasiyana. Kana pasina nzvimbo inotsigira, inokuvadza chisimbiso kumativi ose maviri. Chero bedzi iyo valve yebhora ichishandiswa, inokonzera mamwe madhigirii akasiyana ekurasikirwa kwekumanikidza. Kana bhora rine chitsigiro chekutsigira, hachizokonzeri kurasikirwa kwekumanikidzwa kana kudzvinyirira kurasikirwa kwepamusoro kuchava kuduku zvikuru, saka hupenyu hwevhavha yakagadzika yebhora yakareba kupfuura iyo yemhando inotenderera. , Zviri nani kushandisa yakagadziriswa bhora valve mune dzimwe nguva ine yakakwirira switching frequency.

Ball valvekuisa chisimbiso

Mavharuvhu ebhora anosanganisira V-shaped ball valves, eccentric half ball valves,PVC bhora mavharuvhu, nezvimwewo.

Aya mavharuvhu akasiyana anotsanangurwa zvichienderana nenguva dzakasiyana

V mhando yebhora vharafu

Iyo inoyerera nzira yeV-yakaita bhora vharafu ivharuvhu yebhora ine yakachekwa V port, inova yakagadziriswa bhora vharafu.

Chiyero chekushandisa: Iyo V port yakagadziriswa zvakanyanya. Iyo iine V-shaped incision. Kufanana nebanga, basa raro kucheka dzimwe shinda. Kune zvimwe zvimedu zvakasimba, zvichange zvichipwanywa zvakananga. Nzira yekugadzira bhora yakasiyanawo. Kunyanya mamwe mafekitori ane tsvina yetsvina kana imwe yakaoma granular media, senge rudzi urwu rweV-shaped bhora vharafu rinonyanya kushandiswa.

Eccentric hafu yebhora vharafu

Iyo eccentric hemispherical valve yakafanana neV-shaped ball valve. Iyo yevhavha yepakati inongova hafu, uye zvakare yakagadziriswa bhora vharafu. Inonyanya kushandiswa kune yakasimba particles. Mavharuvhu ese akasimba ebhora anoshandisa eccentric hemispherical valves. Miti yakawanda yesimende inoshandisawo izvi.

Ose ari maviri V-yakaita bhora vharafu uye eccentric semi-bhora vharafu haina unidirectional uye inogona kungoyerera munzira imwe chete, kwete bidirectional kuyerera, nekuti bhora rayo rakavharirwa kune rimwe divi, uye chisimbiso hachizove chakasimba kana charohwa ne reverse side, asi inoyerera chete munzira imwe. Kuiswa chisimbiso kuchave kwakasimba kana kudzvanywa kuchiiswa.

PVC bhora vharafu

Zvisimbiso zvePVC mavharuvhuinongova EPDM (ethylene propylene diene monomer), FPM (fluorine rubber)

Hard seal ball valve

Chisimbiso chakaoma chine chinhu chakakosha

Kune chitubu kuseri kwechigaro chevhavha yakaoma-chisimbiso, nokuti kana chigaro chevhavha yakaoma-chisimbiso uye bhora zvakabatana zvakananga pamwe chete, hazvizotenderera. Apo chitubu chakabatanidzwa shure kwechigaro chevhavha, bhora richava nekushanduka panguva yekutenderera, nokuti chisimbiso chakaoma Dambudziko rinogadziriswa nderokuti bhora rinogona kushanda zvakanaka, asi bhora rinowanzoputirwa nepakati. Kana zvimwe zvimedu zvakanamira muvhavha yechigaro chisimbiso, haigone kushandiswa. Nokudaro, inotambanudza zvishoma uye zvinoenderana nekuoma kwebhora kutambanudza. Kana iri chisimbiso chakapfava, kana zvimedu zvakanamatira muchisimbiso, vharuvhu ichakuvadzwa zvakananga kana yakavharwa. Chisimbiso chakaoma chakafanana neV-shaped ball valve isati yabva mufekitari ine S60 inotarisana. Chisimbiso nebhora zvakaomeswa, saka kazhinji zvinhu zvakaoma. Haiputsika kana ukaikwenya zvishoma

PPL chisimbiso

Chisimbiso zvakare chine PPL zvinhu, zita rayo rinokwidziridzwa PTFE, iyo mbishi ndeye polytetrafluoroethylene, asi imwe graphite inowedzerwa kuti iite kupisa kwekushisa kwepamusoro, tembiricha yepamusoro inogona kusvika 300 ° (kwete kwenguva refu kuramba kusvika 300 ° High. tembiricha), tembiricha yakajairika i250 °. Kana iwe uchida nguva yakareba ye 300 °, unofanira kusarudza yakaoma seal ball valve. Iyo yakajairwa yakakwirira tembiricha kuramba kwechisimbiso chakaoma chinogona kusvika 450 °, uye tembiricha yepamusoro inogona kusvika 500 °.
