Lub clamp thiab flange ntawm npauj npaim valve yog ob hom kev sib txuas. Hais txog tus nqi, cov qhaub cij yog pheej yig, thiab tus nqi yog kwv yees li 2/3 ntawm flange. Yog hais tias koj xav xaiv imported li qub, kom deb li deb tau siv clamping, pheej yig, lub teeb yuag.
Clamping valve ntsia liaj qhov rooj ntev ntev, qhov kev tsim kho qhov yuav tsum tau muaj siab dua, yog tias ob sab ntawm lub flange tsis nyob hauv nruab nrab, lub ntsia liaj qhov rooj yuav raug rau lub zog loj shear, lub valve yog yooj yim to.
Clamping valve bolts feem ntau ntev, thiab nyob rau hauv qhov kub thiab txias, kev nthuav dav ntawm cov bolts tuaj yeem ua rau cov dej xau, yog li nws tsis haum rau cov yeeb nkab loj hauv qhov kub thiab txias. Thiab cov kab npauj npaim valve feem ntau tsis tuaj yeem siv rau qhov kawg ntawm cov kav dej thiab cov dej ntws hauv qab yuav tsum tau muab tshem tawm, vim tias thaum lub flange downstream raug tshem tawm, lub pob valve yuav poob, qhov no, nws yuav tsum tau ua nyob rau hauv lwm sub. nyob rau hauv thiaj li yuav disassemble, thiab flanged npauj npaim valve tsis muaj teeb meem saum toj no, tab sis tus nqi yuav kuj siab.
Tsis muaj flanges ntawm ob qho kawg ntawm lub cev npauj npaim valve, tsuas yog ob peb lub qhov taw qhia lub qhov taub, thiab lub valve txuas nrog ib txheej ntawm bolts / ceev thiab flanges ntawm ob qho kawg. Nyob rau hauv sib piv, lub disassembly yog yooj yim dua, tus nqi valve yog qis dua, tab sis qhov tsis zoo yog qhov teeb meem sealing nto, ob lub sealing nto yuav tsum tau disassembled.
Lub flanged npauj npaim valve lub cev muaj flanges ntawm ob qho kawg, uas tau txuas nrog cov yeeb nkab flange, thiab cov sealing kuj tseem txhim khu kev qha, tab sis tus nqi valve kuj yog siab heev.
