Taw qhia
Npauj npaim li qub yog ib qho ntawm feem ntau siv li qub hauv kev lag luam. Lawv yog siv rau ntau yam kev siv nrog rau kev tswj cov dej ntws thiab cov khoom siv cais tawm. Muaj ntau hom npauj npaim li qub, txhua tus muaj nws qhov tshwj xeeb thiab qhov zoo. Hauv tsab xov xwm no, peb yuav hais txog peb hom npauj npaim li qub, lawv lub hom phiaj, thiab lawv ua haujlwm li cas.
Hom 1: Wafer Npauj Npaim Valves
Wafer npauj npaim li qub yog tsim los kom haum ntawm ANSI lossis PN flanges. Lawv yog siv los tswj cov dej ntws thiab tsim nyog siv rau hauv cov ntawv thov uas tsis tshua muaj siab. Lub valve yog tsim los ntawm ib tug disc, qia, thiab seals. Thaum lub valve nyob rau hauv ib qho chaw kaw, lub disc yog nias rau ntawm lub rooj zaum, tsim ib lub foob. Thaum lub valve nyob rau hauv ib qho chaw qhib, lub disc yog tig, tso cai rau cov kua los ntawm lub valve.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm wafer npauj npaim li qub yog lawv cov qauv tsim. Vim tias lawv qhov me me thiab qhov profile tsawg, lawv zoo tagnrho rau cov ntawv thov uas qhov chaw muaj tsawg. Lwm qhov txiaj ntsig yog lawv qhov yooj yim ntawm kev teeb tsa. Lawv tuaj yeem yooj yim mounted ntawm flanges nrog ceev thiab bolts, ua rau lawv ceev rau nruab.
Txawm li cas los xij, wafer npauj npaim li qub muaj qee qhov tsis zoo. Lawv tsis tsim nyog siv rau hauv cov ntawv siv high-pressure, vim lawv cov qauv tsim ua rau lawv yooj yim rau kev puas tsuaj los ntawm high-pressure flow. Tsis tas li ntawd, lawv tsis pom zoo siv rau hauv cov ntawv thov uas qhov nruab nrab yog abrasive lossis muaj cov khib nyiab, vim tias cov no tuaj yeem ua rau hnav thiab tsim kua muag rau cov ntsaws ruaj ruaj thiab disc.
Hom 2: Lug Npauj Npaim Valves
Lug npauj npaim li qub yog qhov zoo sib xws hauv kev tsim rau wafer npauj npaim li qub, tshwj tsis yog tias lawv muaj threaded inserts lossis lugs ntawm lawv thaj tsam. Cov lugs no tso cai rau lub valve kom mounted yam tsis tas yuav tsum tau ceev thiab bolts. Hloov chaw, cov lugs tuaj yeem txuas ncaj qha mus rau lub kav dej.
Lug npauj npaim li qub kuj tseem tsim nyog siv rau hauv cov ntawv thov uas tsis tshua muaj siab thiab muaj cov qauv tsim, ua rau lawv zoo tagnrho rau siv hauv qhov chaw txwv. Txawm li cas los xij, lawv muaj qee qhov tsis zoo. Zoo li wafer npauj npaim li qub, lawv tsis tsim nyog siv rau hauv cov ntawv thov siab lossis cov ntawv thov uas qhov nruab nrab yog abrasive lossis muaj cov khib nyiab. Tsis tas li ntawd, vim hais tias lawv xav tau threaded inserts los yog lugs, lawv yog me ntsis nyuaj rau nruab dua wafer npauj npaim li qub.
Hom 3: Flanged Npauj Npaim li qub
Flanged npauj npaim li qub yog hom thib peb ntawm npauj npaim valve. Lawv zoo sib xws hauv kev tsim rau wafer npauj npaim li qub tab sis muaj lub cev dav dua thiab flanged kev sib txuas tsis yog lugs. Qhov no ua rau lawv tsim nyog rau kev siv nyob rau hauv high-pressure applications. Flanged npauj npaim li qub kuj tsim nyog siv rau hauv cov ntawv thov uas qhov nruab nrab yog abrasive lossis muaj cov khib nyiab, vim lawv tsim ua rau lawv tiv taus hnav thiab tsim kua muag.
Flanged npauj npaim li qub yog qhov yooj yim rau nruab. Lawv raug ntsia nruab nrab ntawm flanges siv txiv ntseej thiab bolts, ib yam li wafer npauj npaim li qub. Txawm li cas los xij, lawv yog me ntsis loj dua wafer npauj npaim li qub, uas tuaj yeem ua rau lawv tsis haum rau kev siv hauv qhov chaw txwv.
Xaus
Npauj npaim li qub yog siv dav hauv kev lag luam sib txawv rau ntau yam kev siv. Muaj peb hom npauj npaim li qub, txhua tus muaj nws qhov tshwj xeeb thiab qhov zoo. Wafer npauj npaim li qub yog qhov zoo tshaj plaws rau kev siv hauv cov ntawv thov uas tsis tshua muaj siab, thaum lub pob npauj npaim li qub zoo sib xws, tshwj tsis yog tias lawv muaj threaded inserts lossis lugs. Flanged npauj npaim li qub yog qhov kev xaiv zoo tshaj plaws rau kev siv lub zog siab thiab tuaj yeem tiv taus cov xov xwm abrasive.
Thaum xaiv tus npauj npaim valve, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev thov tshwj xeeb thiab cov kev xav tau. Ua tib zoo xav txog yam xws li siab, qhov nruab nrab raug thauj mus los, thiab muaj qhov chaw yuav pab txiav txim siab hom npauj npaim valve zoo tshaj plaws rau daim ntawv thov.
