Txheej txheem cej luam ntawm cov qauv ntawm kev sib txuas valve kawg lub ntsej muag

Lub valve kev twb kev txuas nto qauv ncaj qha cuam tshuam rau lub valve sealing kev ua tau zoo, installation txoj kev thiab kev ntseeg siab nyob rau hauv pipeline system.TWSyuav qhia luv luv txog cov ntaub ntawv txuas tseem ceeb thiab lawv cov yam ntxwv hauv kab lus no.

I. Flanged Kev Sib Txuas

Txoj kev sib txuas universal ua tiav sealing los ntawm bolted fastening ntawm khub flanges.

Common sealing nto hom:

-Protruding nto: Cov qauv tsim ntau tshaj plaws, nrog rau qhov sib khi nto protruding 2-3mm, haum rau ntau qhov siab (PN10-PN25).

-Concave-convex nto: zoo sealing kev ua tau zoo, haum rau flammable thiab toxic media.

-Groove nto: sealing zoo tshaj plaws, siv rau cov xov xwm txaus ntshai heev thiab kev kub ntxhov.

-Nplhaib kev twb kev txuas nto: Hlau nplhaib gasket, tsim los rau high-pressure thiab high-temperature daim ntaub ntawv. Qhov zoo: Txhim khu kev sealing thiab yooj yim disassembly.

Disadvantages: ntim loj thiab hnyav, tus nqi siab.

II.Kev sib txuas ntawm Wafer

Lub valve nta ib qho tsis-flanged tsim, ruaj los ntawm ntev bolts ntawm cov yeeb nkab flanges. Cov yam ntxwv tseem ceeb muaj xws li cov qauv compact, lub teeb yuag, thiab tus nqi-zoo. Txawm li cas los xij, nws xav tau cov qauv kev teeb tsa siab thiab nyuaj rau kev tswj xyuas. Qhov no tsim yog dav siv nyob rau hauvnpauj npaim li qubthiabcheck li qub.

III.Threaded Connections

Threaded kev twb kev txuas yog ib tug neeg kho tshuab kev twb kev txuas txoj kev uas siv threaded fasteners mus txuas cov khoom thiab yuav disassembled txhua lub sij hawm.

Qhov zoo ntawm kev sib khi: Cov khoom loj loj ua rau cov nqi tsim khoom tsawg heev, uas yog ib qho ntawm cov nqi sib txuas zoo tshaj plaws.

Disadvantages: Nws yog ib qho yooj yim rau loosen nyob rau hauv vibration thiab cuam tshuam load, thiab kev nyuaj siab concentration nyob rau hauv lub hauv paus ntawm xov ua rau nws qaug zog zog tsawg.

IV. Vuam txuas

Qhov kev ruaj ntseg ruaj khov tshaj plaws.

-Type: Butt welding: Lub zog muaj zog, tsis muaj dej tsis kam, haum rau kev ua haujlwm hnyav.

-Plug-in welding txuas: Ib qho yooj yim rau nruab, haum rau cov kav dej me me. Qhov zoo: Zero to, vibration-resistant.

Qhov tsis zoo: 5. Disassembly nyuaj. Lwm hom kev sib txuas: Clamping kev sib txuas: Siv hauv kev lag luam huv huv kom yooj yim tu. Lub tes tsho sib txuas: Siv hauv kev ntsuas thiab hydraulic systems.

Cov ntsiab lus xaiv:

1. Xaiv txoj kev raws li qhov siab thiab qhov kub thiab txias: kev kub siab thiab kub siab yuav tsum tau welded los yog nplhaib sib txuas.

2. Raws li cov yam ntxwv nruab nrab: Rau cov khoom siv phom sij, vuam lossis tenon-joint nto raug pom zoo.

3. Xav txog kev teeb tsa thiab kev saib xyuas: nquag disassembly ntawm flange kev twb kev txuas.

4. Tus nqi thiab qhov chaw: Lub wafer yog kev lag luam thiab kev cog lus.

V. Xaus:

Kev sib txuas zoo yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm ntawm cov kav dej. Tau txais kev cob qhia kws tshaj lij thiab cov lus sib tw ntawm pebnpauj npaim valve, rooj vag valve, thiabcheck li qub. Hu rauTWSnrhiav kev daws teeb meem zoo tshaj plaws rau koj cov kev xav tau.
