Dab tsi yog pneumatic valve

Thaum muas pneumatic li qub, nws tsis zoo tag nrho nyob rau hauv kev lag luam kev lag luam tam sim no ib puag ncig uas tsuas yog cov lus qhia, qeb thiab kev ua haujlwm siab tau teev tseg kom tau raws li kev yuav khoom. Rau kev sib tw ntawm cov khoom lag luam, cov tuam ntxhab ntawm pneumatic li qub tau tsim cov kev hloov tshiab sib txawv raws li lub tswv yim ntawm kev sib koom ua ke ntawm pneumatic li qub, tsim lawv tus kheej cov qauv kev lag luam thiab cov khoom ntiag tug. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau muab tso rau hauv cov kev xav tau hauv kev nthuav dav thaum yuav lub pneumatic valve thiab ncav cuag kev pom zoo nrog cov chaw tsim khoom raws li kev txuas ntawm daim ntawv cog lus pneumatic valve.

1. Cov kev cai dav dav

1.1 cov specification thiab qeb ntawm pneumatic valve yuav tsum tau raws li cov kev cai ntawm pipeline tsim cov ntaub ntawv.

1.2 tus qauv ntawm pneumatic valve yuav tsum qhia tus naj npawb ntawm cov qauv hauv lub tebchaws. Yog tias nws yog tus qauv kev lag luam, cov lus piav qhia txog tus qauv yuav tsum tau qhia.

1.3 lub siab ua haujlwm ntawm pneumatic valve yuav tsum muaj ntau dua lossis sib npaug rau kev ua haujlwm siab ntawm cov kav dej. Ntawm qhov chaw tsis cuam tshuam rau tus nqi, kev ua haujlwm siab uas lub valve tuaj yeem dais yuav tsum siab dua qhov ua haujlwm siab ntawm cov kav dej; ib sab ntawm lub pneumatic valve nyob rau hauv lub kaw lus yuav tsum muaj peev xwm dais 1.1 lub sij hawm lub siab ua hauj lwm ntawm lub valve tsis muaj to; Nyob rau hauv qhov qhib ntawm lub valve, lub valve lub cev yuav tsum muaj peev xwm ua tau ob zaug ntawm kev ua haujlwm siab ntawm lub valve.

1.4 tus qauv tsim ntawm pneumatic valve yuav tsum qhia lub teb chaws tus qauv. Yog tias nws yog tus qauv kev lag luam, daim ntawv cog lus yuav khoom yuav tsum tau txuas nrog cov ntaub ntawv lag luam.

2. Txuj zoo ntawm pneumatic valve

2.1 lub valve lub cev cov khoom yuav tsum yog cov nodular cam khwb cia hlau, thiab lub hom thiab lub cev thiab tshuaj ntsuam xyuas cov ntaub ntawv ntawm cam khwb cia hlau yuav tsum tau qhia.

2.2 cov khoom ntawm lub valve pas nrig yuav tsum yog cov hlau tsis muaj steel (2Cr13), thiab qhov loj-inch valve yuav tsum yog stainless hlau embedded valve pas nrig.

2.3 lub txiv ntoo yog ua los ntawm cam khwb cia txhuas tooj dag los yog cam khwb cia txhuas bronze, thiab nws hardness thiab lub zog yog ntau dua li ntawm lub valve pas nrig.

2.4 lub hardness thiab lub zog ntawm cov khoom ntawm lub valve pas nrig bushing yuav tsum tsis txhob ntau tshaj li ntawm lub valve pas nrig, thiab nws yuav tsum tsis txhob tsim electrochemical corrosion nrog lub valve pas nrig thiab valve lub cev nyob rau hauv cov kev mob ntawm dej immersion.

2.5 khoom ntawm sealing nto

① Muaj ntau hom pneumatic li qub, sib txawv txoj kev sib khi thiab cov khoom siv;

② Rau qhov zoo tib yam wedge gate valve, cov khoom siv, kho txoj kev thiab kev sib tsoo ntawm lub nplhaib tooj liab yuav tsum tau teev tseg;

③ Lub cev, tshuaj lom neeg thiab tshuaj ntsuam xyuas cov ntaub ntawv ntawm cov ntaub ntawv mos mos lub rooj vag valve thiab valve phaj roj hmab hauv ob sab phlu khoom;

4. Tus npauj npaim valve yuav tsum kos cov khoom ntawm lub sealing nto ntawm lub valve lub cev thiab cov khoom ntawm lub sealing cover ntawm npauj npaim phaj; lawv cov ntaub ntawv kuaj lub cev thiab tshuaj lom neeg, tshwj xeeb tshaj yog cov kev cai tu cev, tiv thaiv kev laus thiab hnav-tiv taus ntawm cov roj hmab, feem ntau yog siv NBR thiab peb ethylene propylene roj hmab, thiab lwm yam, thiab nruj me ntsis txwv tsis pub ntxiv cov roj hmab rov qab.

2.6 ncej packing

① Raws li lub pneumatic valve nyob rau hauv cov yeeb nkab network feem ntau yog qhib thiab kaw infrequently, nws yuav tsum tau hais tias lub packing yuav tsis ua hauj lwm rau ob peb xyoos, thiab cov packing yuav tsis muaj hnub nyoog, thiaj li yuav tswj tau lub sealing nyhuv rau lub sij hawm ntev;

② Lub pob valve ncej yuav tsum dais qhov zoo sealing nyhuv thaum nws qhib thiab kaw ntau zaus;

③ Raws li cov kev xav tau saum toj no, lub valve ncej ntim yuav tsum tsis txhob hloov lub neej lossis ntau tshaj kaum xyoo;

④ Yog tias cov khoom ntim yuav tsum tau hloov pauv, lub pneumatic valve tsim yuav tsum xav txog cov kev hloov pauv raws li cov dej siab.
