A tso tsegvalve yog [1] ib qho ncaj-los ntawm valve uas qhib thiab kaw sai sai, thiab tseem siv tau tiv thaiv kev sib cuag nrog qhov nruab nrab ntws thaum qhib siab. Lwm qhov tseem ceeb tseem ceeb yog tias nws yooj yim los hloov kho cov kev tsim kho ntau, yog li ntawd ib lub valve tuaj yeem tau txais ob, peb, lossis txawm tias plaub qhov sib txawv ntws raws. Qhov kev tsim kho no yooj yim, txo tus nqi ntawm li qub siv, thiab txo qee qhov kev sib txuas uas yuav tsum muaj nyob hauv cov khoom siv.
Nws ua haujlwm li cas li qub nrogtso tseglub cev nrog cov kev sib tham raws li kev qhib thiab kaw qhov chaw. Lub ntsaws lub cev tig nrog [2] txhawm rau kom ua tiav kev qhib thiab kaw. Tus me, unpacked, ntsaws valve kuj tseem hu ua "cocker". Lub zog plug ntawm lub plug lub zog feem ntau yog ib lub khob hliav qab (tseem muaj ib lub cev cylindrical), uas tau sib phim nrog lub cev conical orifice ntawm lub zog sib khi. Lub Valve Plug yog qhov ntxov tshaj plaws ntawm valve siv, nrog cov qauv yooj yim, qhib kev nrawm thiab kaw, thiab qis kua dej tsis kam. Qhov Plug Zov Cov Khoom Siv Tseg Tseg rau ntawm Hlau Ua Ntej Cov Hlau Plug thiab feem ntau yuav siv tau yooj yim, thiab feem ntau tsuas yog siv tau yooj yim dua li 1 megapascal) thiab feem ntau ntawm cov kab ke me me (tsawg dua 100 mm) sijhawm.
Classify
Raws li cov qauv txheej txheem, nws tuaj yeem muab faib ua plaub hom: nruj tuav lub valve, ntsaws valve, cov roj-txhaj hluav taws xob. Raws li daim ntawv channel, nws tuaj yeem faib ua peb hom: Ncaj-los ntawm cov ntsaws valve, peb-txoj kev nres valve thiab plaub-txoj kev ntsaws Valve. Muaj kuj mob lub raj pliv li qub.
Plug li qub yog cais los ntawm kev siv nrog rau: Cov roj muag nyuaj, roj-lubricer ntsaws cov li qub, peb-txoj kev thiab plaub-txoj kev plug li qub.
Qhov Zoo
1. Cov ntsaws lub valve yog siv rau kev ua haujlwm nquag, thiab kev qhib thiab kaw tau nrawm thiab lub teeb.
2. Cov kua dej tsis haum ntawm lub ntsaws valve me me.
3. Tus qauv ntsaws valve muaj cov qauv yooj yim, qhov loj me me, lub teeb yuag thiab txij nkawm yooj yim.
4. Kev ua kom zoo tshaj plaws.
5. Nws tsis yog txwv los ntawm kev teeb tsa kev teeb tsa, thiab ntws kev taw qhia ntawm lub nruab nrab tuaj yeem yog lam tau.
6. Tsis muaj kev co, suab nrov tsawg.
Mos-foob Rooj Rooj Rooj Zaum Qub
Mos Feal Gate, Kev Sib Tw Valve, Cov Khoom Siv Ram Rau Cov Kab Tawm thiab Kaw Cov Kev Taw Qhia Tsuas yog kaw tag nrho thiab kaw, tsis tuaj yeem hloov kho thiab cuam. Tus RAM muaj ob qhov chaw sealing, feem ntau siv hom rooj vag valies nrog lub qhov chaw sib txawv yog DN5000, kev ua haujlwm ntawm qhov kub thiab txias: ° C.
Cov ntsiab cai khoom
Lub rooj vag phaj ntawm wedgeRooj Vag DabE tuaj yeem ua rau tag nrho, uas yog hu ua lub rooj vag nruj; Nws kuj tseem tuaj yeem ua rau hauv ib tus yaj uas tuaj yeem tsim me ntsis ntawm deformation los txhim kho nws cov kev ua lag luam thiab ua rau kev sib khi ntawm lub kaum sab xis, uas yog hu ua Elastic Ram.
Mos FoobRooj vag Li Qubtau muab faib ua ob hom: Qhib QwsMos Foob GATE Valvethiab tsaus qws foobrooj vag valveCov. Feem ntau muaj cov xov Trapezoidal ntawm lub Lifting pas nrig, uas hloov cov lus tsa suab hauv nruab nrab ntawm lub cev thiab cov kev ua haujlwm ntawm lub zog rau hauv kev ua haujlwm thawb. Thaum lub valve tau qhib, thaum lub RAM nqa qhov siab sib npaug nrog cov kua hluav taws xob, tab sis txoj haujlwm no tsis tuaj yeem raug saib xyuas thaum lub sijhawm ua haujlwm. Hauv kev siv tiag tiag, nws yog cim los ntawm cov vertex ntawm lub qia, uas yog, txoj haujlwm uas tsis tuaj yeem qhib, raws li nws qhib txoj hauj lwm. Txhawm rau kom tau txais kev kaw-nce vim qhov ntsuas kub hloov pauv, feem ntau nws qhib rau lub apex txoj hauj lwm thiab tom qab ntawd revened rov qab 1 / 2-1 tig raws li txoj hauj lwm ntawm lub siab qhib valve. Yog li ntawd, cov chaw qhib tag nrho ntawm lub pob valve yog txiav txim los ntawm txoj hauj lwm ntawm RAM (piv txwv li tus mob stroke). Hom hluav taws xob no feem ntau yuav tsum muab ntsia tau kab rov tav ntawm cov raj xa dej.
