Npauj npaim valve tsis yog tsuas yog siv dav hauv roj av, roj, tshuaj lom neeg kev lag luam, kev kho dej thiab lwm yam kev lag luam, tab sis kuj siv rau hauv cov dej txias ntawm qhov chaw nres tsheb thermal. Clamp thiab flange yog ob hom kev sib txuas. Ob qhov kawg ntawm flanged npauj npaim valve lub cev yog feem txuas nrog cov yeeb nkab flange. Tsis muaj flanges ntawm ob qho kawg ntawm npauj npaim valve lub cev, tsuas yog ob peb phau ntawv qhia lub qhov taub, thiab lub valve txuas nrog qhov kawg flange nrog ib txheej ntawm bolts / ceev. Npauj npaim li qub yog pheej yig thiab lub teeb hauv qhov hnyav. Xaiv cov khoom txawv teb chaws, kom deb li deb tau nrog hom clamp.
Clamping valve bolt ntev ntev dua, qhov kev tsim kho qhov yuav tsum tau muaj siab dua, yog tias ob sab ntawm flange tsis nyob hauv nruab nrab, lub ntsia liaj qhov rooj yuav raug rau lub zog loj shear, lub valve yog yooj yim rau xau. Nyob rau hauv sib piv, lub clamp npauj npaim valve disassembly yog yooj yim dua, tus nqi valve yog qis dua, tab sis qhov tsis zoo yog qhov teeb meem ntawm qhov sib khi, ob qhov chaw sib khi yuav tsum tau disassembled. Flanged npauj npaim valve foob yog qhov txhim khu kev qha ntau dua, tab sis tus nqi valve yog qhov siab. Thiab cov kab npauj npaim valve feem ntau tsis tuaj yeem siv rau qhov kawg ntawm cov raj xa 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 qhov teeb meem saum toj no, tab sis tus nqi yuav kuj siab.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 xau, yog li nws tsis haum rau cov yeeb nkab loj diameters nyob rau hauv qhov kub thiab txias.
Lub clamping npauj npaim valve flange tseem hu ua npauj npaim flange los yog clamping tshwj xeeb flange, uas yog qhov tshwj xeeb flange rau clamping npauj npaim valve nyob rau hauv lub raj xa dej, thiab qhov sib txuam ntawm lub clamping npauj npaim valve. Lub ntsiab sib txawv ntawm qhov tshwj xeeb flange ntawm lub clamping npauj npaim valve thiab cov flange zoo tib yam yog lub puab kab uas hla ntawm lub flange, lub puab txoj kab uas hla ntawm qhov tshwj xeeb flange tsuas yog nrog lub nominal txoj kab uas hla ntawm qhov yuav tsum tau npauj npaim valve nyob rau hauv lub nraub qaum ntawm ib lub qhov. qhov yuav tsum tau muab tso rau hauv cov yeeb nkab steel txuas, kom ntseeg tau tias cov nyhuv sealing ntawm lub clamping npauj npaim valve, yog tias siv cov flange zoo tib yam, cov nyhuv sealing ntawm npauj npaim valve tsis tau lav. Tsis tas li ntawd, sab nraud txoj kab uas hla, thickness, nruab nrab nrug thiab ntsia liaj qhov rooj qhov tshwj xeeb flange ntawm lub clamp npauj npaim valve yog tib yam, thiab bolts siv yog ob lub taub hau bolts. Kev siv cov bolts yog hloov raws li qhov kub ntawm kev siv sib txawv.
