Cov khoom siv wireframe
Thaum cov xov xwm raug tso tawm los ntawm lub tshuab nqus dej mus rau lub qhov tso dej tawm, qhov rov qab ntws yuav tshwm sim thaum lub twj tso kua mis nres. Check valves yog siv los tiv thaiv qhov no. Hom valve feem ntau siv rau qhov no yog ko taw valve.
Lub check valve muaj ob qhov chaw nres nkoj - qhov nkag thiab qhov hluav taws xob - thiab lub tshuab kaw / kaw. Cov yam ntxwv tshwj xeeb ntawm cov pob valve uas txawv ntawm lwm hom li qub xws li pob thiab npauj npaim li qub yog tias, tsis zoo li cov li qub no uas xav tau qee yam kev ua haujlwm los ua haujlwm, kos li qub yog tus kheej ua haujlwm. Kuaj li qub ua haujlwm tau txais, tso siab rau qhov sib txawv siab kom tswj tau qhov zoo. Nyob rau hauv lawv txoj haujlwm ua ntej, cov tshev valve raug kaw. Thaum xov xwm ntws los ntawm qhov chaw nres nkoj inlet, nws lub siab qhib lub kaw mechanism. Thaum lub siab ntws tawm hauv qab lub siab tawm vim qhov ntws raug kaw, lossis lub siab ntawm lub qhov hluav taws xob sab nraud ua ntau dua vim li cas, lub kaw lus kaw tam sim ntawd kaw lub valve.
