Valovu ya mpira wachimuna wamitundu iwiri

Kutchuka kwa Sayansi ya Shenchi: Kodi valavu yapamwamba kwambiri yamitundu iwiri yokhala ndi ulusi wachimuna ndi chiyani?

Valavu yokhala ndi mbali ziwiri yakunja ya ulusi wakunja ndi valavu ya mpira yokhala ndi ulusi wachimuna kumbali zonse ziwiri, zosonkhanitsidwa kuchokera ku zigawo ziwiri za thupi. Mtundu wa Shenchi wa valavu iyi umapereka zida zathupi zamkuwa, SUS304, kapena SUS316L, ndi chitsulo chamkati chofananira ndi thupi kuti athetse chiwopsezo cha dzimbiri. Amagwiritsa ntchito zisindikizo za EPDM ndi ntchito yamanja, yoyenera madzi, mpweya, mafuta, gasi ndi zofalitsa zofanana. "Valavu yapamwamba kwambiri yamitundu iwiri yakunja" imatanthauzidwa ndi kulondola kwa ulusi wapamwamba, torque yochepa yogwiritsira ntchito, moyo wautali wa chisindikizo, ndi kugwirizana kwachindunji kwa madoko opangidwa ndi akazi opanda ma adapter owonjezera.

Kuyang'anira Kuyikiratu ndi Kufotokozera kwa Ulusi wa Shenchi Two-Piece Double External Thread Ball Valve

Shenchi, wopereka ma valve akunja awiri akunja kuchokera ku China, amalimbikitsa kuyang'ana kuti ulusi wakunja wa valavu sunawonongeke ndipo umagwirizana bwino ndi ulusi wa chitoliro chachikazi musanayike. Ikani tepi yocheperako ya PTFE mofanana mu ulusi wa 2-3. Shenchi's premium-piece two double-threeball valve valve ili ndi ma wrench flats pamizu ya ulusi. Gwiritsani ntchito wrench yotseguka pamafuletiwa pakuyika; musamatembenuze gawo lapakati la valavu kuti mupewe kusokoneza phata la mpira wamkati.

Mfundo Zofunika Pakuyika Chisindikizo ndi Kuwongolera kwa Torque ya Thupi la Valve

Zigawo zazikulu za valavu ziwiri zakunja zakunja za ulusi zimaphatikizapo magawo awiri a thupi, pakati pa mpira, tsinde, ndi zisindikizo za EPDM. Mu mapangidwe a Shenchi, matupi awiriwa amalumikizana kudzera pa ulusi wapakati. Onetsetsani kuti gasket yosindikiza (pakati pa theka la thupi) yakhazikika popanda skew. Limbitsani dzanja mpaka mutalumikizana, ndiye gwiritsani ntchito chida chowonjezera cha 1/4. Torque yochulukirapo idzasokoneza zisindikizo za EPDM ndikupangitsa kulephera. Valavu yotsika mtengo yamitundu iwiri yakunja siyenera kusokoneza kusindikiza; Kuwongolera koyenera kwa torque kumakhudza moyo wa valve.

Njira Yosinthira Pamalo Yosindikizira Ma Valve Stem ndi Kusintha kwa Limiting Mechanism

Valavu yakunja ya Shenchi yamitundu iwiri yakunja imakhala ndi chisindikizo cha EPDM O-ring pa tsinde. Mukayika, yendetsani valavu kawiri kawiri kuti muwone ngati pali kutayikira pa tsinde. Ngati kutayikira pang'ono kumachitika, limbitsani pang'onopang'ono nati wonyamula (osapitirira 1/8 kutembenuka). Komanso zindikirani malire amasiya chogwirira: chogwirizira chofanana ndi chitoliro chikuwonetsa kutseguka; perpendicular amasonyeza kutsekedwa. Valavu yoyambira yamitundu iwiri yakunja imaphatikizapo kuyimitsidwa kwamakina pamalo apamwamba kwambiri. Osakakamiza kupitilira maimidwe awa, kapena kuwonongeka kwapakati pa mpira ndi malo osindikizira zitha kuchitika

Kupewa Zolakwika Zoyikira Pamodzi ndi Njira Zoyesera Kusindikiza Pamalo

Mukayika valavu ya ulusi wa Shenchi, pewani: kukulunga kwambiri ulusi wokhala ndi zosindikizira zomwe zimayambitsa zinyalala muzitsulo za valve, pogwiritsa ntchito ma wrenches a chitoliro pa thupi la valve, kapena kulephera kuyeretsa zinyalala za chitoliro musanayike. Njira yolondola: yesani kukakamiza mukatha kukhazikitsa, tsegulani valavu pang'onopang'ono, ikani madzi asopo pazolumikizana zonse zolumikizidwa ndi mafupa amthupi, ndipo samalani kuti pakhale thovu. Valavu yapamwamba yamitundu iwiri yakunja yakunja iyenera kukhala yopanda kutsika kwa mphindi zisanu pa mayeso a PN16. Pambuyo poyesa, siyani valve yotsegula theka kuti muteteze kupanikizika kwa chisindikizo kwa nthawi yaitali kumbali imodzi.
