Taw qhia rau Flexible Wedge Gate li qub
Flexible Wedge: Ib qho yooj yim Wedge rooj vag valve muaj ib tug disk nrog ib tug txiav nyob ib ncig ntawm lub perimeter. Ib qho kev txiav ntiav ua kom yooj yim dua. Ib txoj kev sib sib zog nqus ua kom yooj yim dua. Flexible Wedge gate valves feem ntau yog siv hauv chav tshuab. Lub rooj vag hloov tau txwv tsis pub lub disc los ntawm kev khi rau hauv lub rooj zaum thaum cov kab raug cua sov uas tuaj yeem ua rau muaj kev cuam tshuam ntawm lub cev valve.
Seat Ring Design nyob rau hauv rooj vag li qub
Seat Rings hauv Gate Valves tuaj yeem muab faib ua ntau pawg hauv qab no:
Integral Lub Cev Lub Cev Ntiv Nplhaib.
Rov ua dua lub rooj zaum Rings uas tuaj yeem yog threaded lossis nias haum rau hauv lub cev ntawm lub valve. Qhov no ua kom yooj yim tshem tawm thiab hloov cov nplhaib lub rooj zaum.
Tsis yog-Txoj Rings Rov Ntxiv Lub Rooj Zaum uas tau muab welded los yog tag nrho welded rau lub cev ntawm lub valve.
Qhov zoo ntawm Gate Valves
Qee qhov zoo ntawm Gate Valves yog raws li hauv qab no:
Lub rooj vag li qub muaj qhov zoo kaw-tawm cov yam ntxwv raws li kev sib cuag ntawm lub disk thiab lub nplhaib lub rooj zaum txuas mus rau tag nrho ib ncig.
Lub siab poob thoob plaws lub rooj vag valve yog qhov tsawg vim tias lub disk tsis muaj kev tiv thaiv kom ntws thaum lub valve nyob rau hauv qhov chaw qhib tag nrho.
Lub rooj vag li qub yog ob- cov lus qhia taw qhia thiab tuaj yeem muab kaw- tawm hauv ob qho kev qhia ntws.
Disadvantages ntawm Gate Valves
Qee qhov tsis zoo ntawm Gate Valves yog raws li hauv qab no:
1.Txoj kev mus rau hauv lub rooj vag valve yuav tsum muaj ntau yam lem ntawm lub tes log lossis iav tus neeg teb xov tooj thiab yog li lub sijhawm ntev dua los qhib lossis kaw lub valve.
2.Raws li lub rooj vag lossis lub npoo yuav tsum hla tag nrho tus ntoo khaub lig- ntu ntawm lub valve, qhov siab tag nrho ntawm lub rooj vag valve loj dua piv rau lub pob valve uas yog lub quarter tig valve thiab tsis tas yuav tsum tau txav ntsug ntawm lub qia.
3.Gate li qub tau muab cov rooj zaum txuas ntxiv uas feem ntau nyuaj rau hloov tawm hauv -situ.
4.The valve flow characteristics of gate valve can cause high velocity of flow to occur for longer duration while the opening or closing the valve due to slow movement of wedge or gate. High velocities can cause erosion of seat and the disc thereby reducing the design life of the valve. This condition is also referred to as "wire drawing" effect.
5.Gate li qub yog qhov cuam tshuam rau cov khoom sib txuas lossis disc tau daig ntawm cov rooj zaum vim qhov sib txawv ntawm qhov sib txawv ntawm lub rooj zaum valve thiab lub npoo thaum kaw cov kav dej kub. Cov kav dej yuav tsum tau rov ua kom lub disc rov qab mus zoo dua. Qhov no ua rau lub rooj vag valve tsis haum rau kev siv hauv cov kav dej uas muaj kev hloov pauv ntawm qhov kub thiab txias. Txawm li cas los xij, qhov teeb meem no tuaj yeem kov yeej los ntawm kev siv lub rooj vag valve nrog cov wedges hloov tau.
6. Lub rooj vag li qub uas yog hlau zaum tsis muaj npuas - kaw nruj - tawm thiab yuav tsum tsis txhob siv rau hauv cov ntawv thov uas muaj qhov dej me me hla lub rooj zaum tsis tso cai.
