1. Threaded kev twb kev txuas
Threaded kev twb kev txuas yog kev sib txuas ntawm ob qhov kawg ntawm lub valve, uas tau ua tiav rau hauv cov xov sab hauv lossis sab nraud, thiab cov kav dej. Feem ntau, pob li qub hauv qab 4 ntiv tes thiab lub ntiaj teb li qub, lub rooj vag li qub thiab kos li qub hauv qab 2 ntiv tes feem ntau yog xov. Cov qauv kev sib txuas threaded yog qhov yooj yim, lub teeb hauv qhov hnyav, thiab yooj yim rau nruab, disassemble, kho thiab hloov.
2. Flange kev twb kev txuas
Flange kev twb kev txuas yog qhov zoo tshaj plaws thiab feem ntau txoj kev sib txuas hauv li qub. Nws yog yooj yim heev rau nruab thiab disassemble, thiab flange kev twb kev txuas yog txhim khu kev qha nyob rau hauv sealing. Nws muaj ntau dua nyob rau hauv high-pressure thiab loj-inch li qub. Txawm li cas los xij, qhov kawg flange yog hnyav thiab tus nqi kuj tseem siab.
3. Kev sib txuas ntawm vuam
Vuam kev sib txuas feem ntau muaj ob hom qauv: qhov (socket) vuam thiab taub qab vuam. Feem ntau hais lus, qhov (socket) welding yog siv rau cov valve uas tsis tshua muaj siab. Lub vuam qauv ntawm lub qhov (socket) vuam li qub yog yooj yim rau txheej txheem, thiab vuam installation kuj yooj yim; taub qab vuam kev twb kev txuas yog siv rau high-pressure li qub, tus nqi yog siab dua, lub taub qab vuam yuav tsum tau grooved raws li pipeline qauv, thiab cov txheej txheem yog ntau nyuaj.
4. Clamp kev twb kev txuas
Clamp kev twb kev txuas muaj lub teeb qauv thiab tus nqi qis, thiab feem ntau yog siv rau hauv cov kav dej huv thiab cov khoom siv. Cov kav dej huv yuav tsum tau ntxuav, thiab nws yog nruj me ntsis txwv tsis pub muaj cov seem uas tsim cov kab mob. Clamp kev twb kev txuas yog txoj kev txuas feem ntau rau cov kav dej huv.
