Nzira yekuwana sei kukurumidza kuvhura uye kuvhara kwebhora mavharuvhu?

Kukurumidza kuvhurwa nekuvhara kwebhora mavharuvhuinonyanya kutsamira pane yavo inotenderera dhizaini dhizaini uye yakaderera friction yekuisa chisimbiso michina. Iyo chaiyo musimboti ndeiyi inotevera:

1. 90 ° kutenderera kuvhura nekuvhara

Iyo valve core yebhora vharafuyakaita denderedzwa uye ine buri mukati. Kana mubato kana mudziyo wekutyaira uchityaira bhora kuti ritenderere 90 °, iyo kuburikidza-gomba uye vharafu muviri chiteshi inoshanduka kubva yakanyatsoenderana (yakavhurika) kuenda perpendicular (yakavharwa), kana kushanda iri mhiri. Iyi dhizaini inobvumira kuvhura nekuvhara kuita kuti kupedzwe muchikamu chimwe chete chechina chekutendeuka, nekukurumidza zvakanyanya kupfuura mavharuvhu akadai semavharuvhu egedhi nemavharuvhu eglobhu anoda kutenderera kwakawanda.

2. Yakaderera torque dhizaini

Streamlined sphere: Nzvimbo yepasirendi yakatsetseka, ine kushomeka kwekudzivirira kana mvura ichipfuura. Kana yakavhurwa, iyo yepakati pressure inogona kubatsira mukusundidzira sphere, kuderedza kushanda torque.

Inoyangarara kana yakagadziriswa bhora chimiro:

Bhora rinoyangarara vharafu: Bhora rinoyangarara richidzika rakananga kunzvimbo yekuvharisa pasi pekumanikidzwa kwepakati, richigadzira self seal, uye simba rinoshanda rinongoda kukunda kukwenya kwemhete yekuvharisa.

Fixedbhora vharafu: Bhora rinogadziriswa nepamusoro uye pasi pevhavha stems uye yakakodzera kune yakakwirira-kudzvinyirira mamiriro. Iyo inoderedza kutenderera kutenderera kuburikidza nemabhengi uchichengeta yakaderera torque maitiro.

3. Optimization yekuisa chisimbiso chimiro

Elastic sealing ring: yakadai sePTFE (polytetrafluoroethylene) kana simbi yekuisa chisimbiso mhete, inonamatira zvakasimba kune sphere pasi pe pre tension, asi ine yakaderera friction coefficient uye yakaderera kuramba panguva yekutenderera.

Bidirectional sealing: Mamwe mavharuvhu ebhora akagadzirwa ane bidirectional sealing, iyo inogona kukurumidza kutema fluid zvisinei nekuyerera kwepakati, pasina kudikanwa kwekugadzirisa nzira yekushandisa.

4. Chishandiso chekutyaira chekubatsira

Manual mashandiro: Iyo pfupi mubato kana lever dhizaini inogona kukwidziridza simba rekushanda uye kuwana nekukurumidza kutenderera.

Magetsi/pneumatic actuator: Inotyairwa nemota kana silinda, inogona kupedzisa kuvhura nekuvhara mukati memasekonzi 0.5-5 uye inokodzera automation control system.

Mamiriro ekushandisa akajairika

Emergency shutdown: senge masystem ekudzivirira moto uye mapaipi egasi, anoda kuvharwa mukati memasekonzi mashoma kudzivirira njodzi kuti isakwira.

High frequency regulation: Kuti udzore kuyerera mumakemikari maitiro, zvinodikanwa kukurumidza kushandura kuvhura kuti uchengetedze yakagadzikana maitiro paramita.

Pfupiso: Mavharuvhu ebhora awana kumhanya kwekuvhura nekuvhara zvakanyanya kupfuura mamwe mavharuvhu kuburikidza ne90 ° kutenderera, yakaderera torque dhizaini, chisimbiso optimization, uye dhiraivha rubatsiro rwechishandiso, ichivaita sarudzo yakasarudzika yekukurumidza mhinduro mamiriro.
