(a) Maitiro ekushanda evhavha yakachekwa
Iyo inoshanda torque hunhu curve yevhavha yakachekwa yakakwira nepakati uye yakaderera kumativi ese.
Chikonzero chemamiriro ezvinhu aya ndechekuti, kana vharuvhu yakachekwa iri panzvimbo yepakati, mvura yacho yakavharwa nendiro yeshavishavi, inotenderedza butterfly plate liquidity, ichagadzirwa kumativi ose eshavishavi ndiro inotenderera ikozvino, butterfly. ndiro inoburitsa nguva yekumberi-yekupedzisira mvura, nguva yacho inofambiswa kudzima ndiro ye butterfly. Nekuvhurwa kana kuvharwa kweplate ye butterfly, simba remvura pamativi maviri e butterfly rinokonzerwa nekuyerera kwevortex idiki uye idiki, kusvika dutu raserera, panguva ino kupesana kwekupokana kweshavishavi ndiro zvakare kudiki. uye zviduku, zvichiita kuti nzvimbo yakakwirira, maitiro akaderera emativi maviri emufananidzo. Iyo chaiyo yekushanda torque mukuvhura nzira yevhavha yegedhi yakakura kupfuura iyo mukuvhara maitiro. Chikonzero chikuru ndechekuti iyo hydrodynamic torque inokonzerwa nemvura iri pa butterfly plate inogara yakananga kuAngle yekuvhara.
Iyo hombe chaiyo yekushanda torque yeiyo isina-hermetically yakavharwa yekumisa vharafu inoitika munzvimbo yepakati, nepo hombe chaiyo inoshanda torque yehermetically yakavharwa yekumisa vharafu inoitika kana vharafu regedhi rakavharwa, kunyanya nekuda kwekuwedzera kwekumanikidzirwa kuvhara torque.
Chigaro chevhavha yevhavha yakachekwa chete yekufamba-famba, disc yayo uye chigaro pachayo haina kukiyiwa simba. Kuti uite dhisiki chaiyo yekumisikidza (kugumisa panzvimbo yakatarwa), imwe nzira inoda imwe inoderedza nekuvhara simba pachigaro. Mushure mekuwedzera kuderedzwa kwepuraneti, iyo angular kumhanya inogona kuwedzerwa kusvika kune gumi nemaviri ekutendeuka, nepo chaiyo inoshanda torque yakaderedzwa. Izvi zvinobvumira mamwe maitiro chaiwo ekushanda kwevhavha yakachekwa (yakadai sekutendeuka kwese uye torque chaiyo yekushanda) kuti ive pedyo nemamwe mavharuvhu emagedhi, ayo anobatsira pakushandiswa kwemagetsi emagetsi.
Nokuda kwekuvhara kwekumanikidzirwa kwevhavha yakachekwa, nzvimbo yaro yekuvhara inofanira kugadziriswa neyo chaiyo inoshandiswa torque inokwira kuhuwandu hwehuwandu.
(2) Valve inoshanda maitiro Valve inoshanda torque maitiro:
Iyo inoshanda torque hunhu dhizaini yevhavhavha yebhora yakafanana neiyo yevhavha yakachekwa, chikonzero chikuru zvakare nekuda kwesimba rekuyerera kwemvura kunokonzerwa nekuchinja kwekupinda mukati mechikamu. Mhedzisiro yemhepo inoyerera zvishoma nezvishoma inoderera nekuvhurwa kana kuvhara kwevhavha.
Bhora vharafu kubva pakuvhurwa kusvika pakuvhara, chigaro chevharuvhu chinotenderera kutungamira i90%, bhora vharafu kuseta mekiniki muganho. Kutanga kana kuvhara chikamu chevhavha yebhora kunofanira kugadziriswa nekutungamira kwekutenderera kwechigaro chevhavha, saka bhoti yebhola inogadziriswa maererano nehurongwa hwekufamba.

Flange ball valve applicator
1, iyo fekitori nameplate inoratidza kuti flange bhora vharafu inotenderwa kushanda pane yakakura tembiricha kana ichienzaniswa nediki rekushanda tembiricha yegiredhi reKing Kong.
2, flange bhora vharafu ine PTFE kana RTFE zvinhu yakakwira kumanikidza gedhi vharafu uye hydraulic seals, tembiricha yekushanda inofanirwa kunge iri pakati pe -290C kusvika 2000C. Iyo tembiricha yekushanda yemamwe marudzi ekumanikidza kwegedhi mavharuvhu uye hydraulic seals ichaongororwa neKI fekitori.
3, iyo yezita dhayamita yekirasi yevharuvhu (PN), inogona kuratidza kuti vharafu iri muyakajairwa tembiricha mamiriro yakakura kwazvo kumanikidza. (Semuenzaniso: PN4.0, zvichiratidza kuti tembiricha yekushanda ye -290C ~ 380C mushure mekumanikidzwa kukuru kwe40 Bar (4.0MPa)).

Imwe, vharafu yebhora inoyangarara
Bhora revhavha bhora ririkuyangarara kumusoro nekudzika, pasi pesimba rekushandisa kumanikidza, bhora rinogona kuburitsa imwe dhizaini uye yakasimba pane inopinza end surface, kuve nechokwadi chekuti chinobuda chinopera chisimbiso. Inoyangarara bhora vharafu chimiro chiri nyore, compact chimiro, asi bhora rinotora mutoro wemidhiya yese kune inopinza uye yekubuda chisimbiso mhete, saka isu tinofanirwa kunzwisisa kuti rabha yekuisa chisimbiso mhete inogona kumira bhora repakati basa rekutakura. Ichi chimiro chinoshandiswa kune yepakati uye yakaderera kumanikidza bhora mavharuvhu.
Mbiri, yakagadziriswa bhora vharafu
Bhora revhavha bhora rinogara, mushure mekunge simba risingafambiswi. Fixed bhora mavharuvhu anouya neanochinja-chinja high pressure gedhi mavharuvhu. Mushure mekushandiswa kwezvinhu zvekushanda, iyo yakakwira yekumanikidza gedhi valve inofambiswa, kuitira kuti mhete yekuisa chisimbiso isimbiswe zvakasimba pabhora kuti ive nechokwadi chekusimba. Kazhinji mukati uye jira rebhora, iyo shaft yezasi ine inotenderedza mabhengi, diki control torque, yakakodzera kune yakakwira uye diki caliber valve muviri. Kuti uderedze torque yekushanda yevhavha yebhora uye kuwedzera kuvimbika kwechisimbiso, skeleton yakavharwa bhora valve yakaonekwa mumakore achangopfuura. Haisi chete kubheja yakakosha girisi pakati pepamusoro kuti iite musara wemafuta inotsvedza, iyo inovandudza kusimba uye inoderedza iyo chaiyo yekushandisa torque. Iyo inonyanya kukodzera kuvhavha yebhora ine simba guru uye duku dhayamita.
Tatu, elastic bhora vharafu
Bhora revharuvhu yebhora rakatsikirirwa. Bhora uye yakakwira yekumanikidza gedhi revhavha chisimbiso mhete inogadzirwa nesimbi inoumbwa zvinhu, yekuisa chisimbiso kumanikidza yakakura kwazvo, zvinoenderana nekumanikidza kwechinhu chacho chapfuura zvinodiwa nekuvhara, kudiwa kwekuwedzera simba rekunze. Iri vharafu regedhi rakakodzera kune ultra-high pressure uye yakakwirira tembiricha zvinhu. Elastic sphere yekuvhura goko rinogoneka pasi pe sphere cavity, uye kuwana elastic simba. Kana chiteshi chekuchengetedza chadzimwa, bhora rinovhurwa nemusoro weji wepiston tsvimbo uye yakakwira yekumanikidza gedhi vharafu inodzvanywa kuti iwane chisimbiso. Usati watenderedza bhora, tanga wasunungura wedge musoro, bhora nekudzoka kune yakajairwa prototype, kuitira kuti bhora nevhavhavhavha pakati pepakati, inogona kuderedza iyo chaiyo oparesheni torque ye friction surface.

Bhora vharafu zvinoenderana nenzvimbo yayo yekuchengetedza chiteshi inogona kukamurwa kuita yakananga kubatana, nzira nhatu kana yekurudyi Angle. Iwo maviri ekupedzisira mavharuvhu ebhora anoshandiswa kugovera zvinhu uye kushandura kuyerera kwe media. Kuiswa kwebhora revhavha nekugadzirisa zvinoda kubhadhara kune zvinotevera: 1. Siya chikamu chinotenderera chemubato wevhavha. 2. Haikwanise kushandiswa sevhavha yemhepo. Mavharuvhu ebhora ane michina yekutumira anofanirwa kuunganidzwa akatwasuka.
