Lub tshuab nqus tsev npauj npaim valve yog tsim rau kev tiv thaiv ib puag ncig ntawm cov neeg tsim khoom, thee gas, natural gas, liquefied petroleum gas, lub nroog gas, huab cua kub thiab txias, tshuaj lom neeg kev cob qhia thiab lub zog tsim. Nws yog siv rau cov dej num ntawm kev txias thiab txiav tawm xov xwm ntawm cov kav dej uas thauj ntau yam corrosive thiab tsis yog -corrosive fluid media hauv engineering systems xws li kev tsim cov dej thiab cov kua dej.
The gate valve is an opening and closing gate. The movement direction of the gate is straight with the direction of the fluid. The gate valve can only be fully opened and fully closed. '. To improve its manufacturability and compensate for the error of the sealing surface viewpoint during the processing, this kind of gate is called an elastic gate.
Thaum lub rooj vag valve raug kaw, lub sealing nto tsuas yog cia siab rau qhov nruab nrab siab los muab khi, uas yog, tsuas yog tso siab rau qhov nruab nrab siab los nias lub sealing nto ntawm lub rooj vag mus rau lub rooj zaum ntawm lub valve ntawm sab nraud kom ntseeg tau tias lub sealing ntawm lub rooj vag. lub sealing nto, uas yog tus kheej - sealing. Feem ntau lub rooj vag li qub raug yuam kom kaw, uas yog, thaum lub valve kaw, lub rooj vag yuav tsum tau nias tawm tsam lub rooj zaum ntawm lub rooj zaum los ntawm lub zog sab nraud los xyuas kom meej qhov nruj ntawm lub sealing nto.
