Qhov tseem ceeb sib txawv ntawm antiaj teb valvethiab antsaws valvenyob rau hauv lawv cov lag luam: lub ntiaj teb valve ua tiav qhov qhib thiab kaw thiab cov kev cai ntws ncaj qha los ntawm txoj kev txav ntsug ntawm nws lub valve disc, muab kev sib khi zoo heev tab sis siab txaus; Lub ntsaws valve, ntawm qhov tod tes, tswj kev qhib thiab kaw los ntawm kev tig lub conical ntsaws 90 degree, muab kev qhib thiab kaw nrawm thiab tsis tshua muaj dej tsis kam, tab sis nrog lub peev xwm tswj tsis muaj zog thiab me ntsis sealing stability.
Antiaj teb valvesiv lub valve qia los tsav lub valve disc vertically raws li lub rooj zaum valve, tso cai rau kev tswj kom meej ntawm qhov qhib degree. Nws muaj kev sib khi zoo heev thiab muaj peev xwm tswj tau cov dej ntws, thiab feem ntau yog siv hauv nruab nrab - thiab siab - cov ntawv thov siab uas yuav tsum tau hloov kho, xws li chav dej, roj, lossis cov kav dej tshuaj. Nws cov qauv yog qhov yuam kev, yuav tsum tau ua kom tsis txhob muaj qhov xau thaum kaw, thiab feem ntau muaj "tsawg nkag, qhov hluav taws xob siab" kev taw qhia kev teeb tsa los tiv thaiv lub valve qia thiab ntim.
A ntsaws valveTxawm li cas los xij, ua tiav qhov qhib thiab kaw los ntawm kev tig lub conical lossis cylindrical ntsaws (nrog rau cov channel), tsuas yog xav tau 90℃kev sib hloov. Nws ua haujlwm sai, muaj cov kua dej tsawg tsawg, thiab tsim nyog rau qis - siab, siab - ntws qhov yuav tsum tau kaw sai - tawm, xws li lub teeb kev lag luam, chiv, lossis lub tshuab nqus tsev.
Nws sealing cia siab rau qhov haum haum ntawm lub ntsaws thiab lub valve lub cev, nrog rau kev pab ntawm roj. Kev siv ntev ntev tuaj yeem ua rau hnav lossis jamming, tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias ib puag ncig los yog cov xov xwm uas muaj cov khoom, qhov twg sealing kev ua tau zoo sai sai. Txawm hais tias qee qhov lubricated ntsaws li qub tuaj yeem tiv taus siab, lawv qhov kev tswj xyuas tag nrho yog qhov qis dua ntawm cov rooj vag li qub.

FAQ
Dab tsi yog qhov ntsaws valve siv rau?
Feem ntau muaj nyob rau hauv cov duab cylindrical lossis conical, ntsaws li qub yog peb lub hlis twg -tig phau ntawv taw qhia li qub siv raunres lossis pib cov kua dej. Lawv muab rau -tawm, hloov pauv, nrog rau cov kev pabcuam cuam tshuam nruab nrab. Nyeem rau kom paub meej txog cov ntsaws li qub, nrog rau lawv cov hom thiab cov ntawv thov.
Puas yog ntsaws li qub kim dua li pob li qub?
Nqe Ntau:Plug li qub feem ntau pheej yig dua li pob li qub. Lawv yog cov yooj yim hauv kev tsim thiab tsis xav tau ntau yam complex, ua rau lawv muaj kev xaiv pheej yig dua nyob rau hauv feem ntau.
Dab tsi yog qhov tsis zoo ntawm plug li qub?
Plug li qub feem ntau tsis yog siv rau hauv cov tshuab uas xav tau cov nqi ntws siab heev. Thaum lawv ua haujlwm zoo rau cov dej ntws nruab nrab,qhov tsim ntawm lub ntsaws valve tuaj yeem qhia qhov kev tiv thaiv, uas tuaj yeem tsim kom muaj kev poob qis hauv siab - cov ntawv thov ntws.
