Dab tsi yog pneumatic valve

Pneumatic valve: lub valve tsav los ntawm huab cua compressed.

Nws tsis zoo tag nrho hauv kev lag luam kev lag luam tam sim no qhov kev yuav khoom ntawm pneumatic valve tuaj yeem ua tau raws li qhov yuav tsum tau ua tsuas yog los ntawm kev txhais cov lus qhia, hom thiab kev ua haujlwm siab. 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 qhov kev pom zoo nrog cov chaw tsim khoom raws li qhov txuas ntxiv rau 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 ntaub ntawv.

1.2 tus qauv ntawm pneumatic valve yuav tsum qhia lub teb chaws tus qauv yuav tsum tau muaj. 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 hauj lwm ntawm lub pneumatic valve yuav tsum siab tshaj los yog sib npaug rau kev ua hauj lwm siab ntawm cov kav dej. Ntawm qhov chaw tsis cuam tshuam rau tus nqi, lub siab ua haujlwm uas lub valve tuaj yeem dais yuav tsum siab dua qhov ua haujlwm siab ntawm cov kav dej; Thaum lub pneumatic valve raug kaw, txhua sab yuav tsum muaj peev xwm dais 1.1 npaug ntawm kev ua haujlwm siab ntawm lub valve yam tsis muaj dej; Thaum lub valve qhib, lub valve lub cev yuav tsum muaj peev xwm tuav tau ob zaug ntawm lub siab ua haujlwm ntawm lub valve.

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

2. Txuj zoo ntawm pneumatic valve

2.1 cov khoom siv lub cev lub cev yuav tsum yog cov khoom siv hlau, thiab cov khoom lag luam thiab cov ntaub ntawv kuaj lub cev thiab tshuaj lom neeg ntawm cam khwb cia hlau yuav tsum tau qhia.

2.2 cov khoom qia yuav tsum yog stainless hlau qia (2Cr13), thiab txoj kab uas hla loj yuav tsum yog stainless hlau embedded qia.

2.3 lub txiv ntseej 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 qia.

2.4 lub hardness thiab lub zog ntawm lub valve qia bushing khoom yuav tsum tsis txhob ntau tshaj li ntawm lub valve qia, thiab yuav tsum tsis txhob muaj electrochemical corrosion nrog lub valve qia 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, txoj kev sib khi thiab cov khoom siv;

② Kev sib tsoo lub rooj vag valve, cov khoom siv tooj liab, txoj kev ruaj khov, kev sib tsoo yuav tsum tau piav qhia;

③ Physicochemical thiab kev kuaj 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 Cov khoom ntawm sealing nto ntawm lub cev lub cev thiab npauj npaim phaj yuav tsum tau cim rau ntawm npauj npaim valve; Lawv cov ntaub ntawv kuaj lub cev thiab tshuaj lom neeg, tshwj xeeb tshaj yog kev tu cev, kev laus ua haujlwm thiab hnav tsis kam ntawm roj hmab. Nitrile roj hmab thiab ethylene propylene diene monomer feem ntau yog siv, thiab cov roj hmab rov siv dua yog txwv nruj heev.

2.6 valve ncej packing

① Raws li lub pneumatic valve nyob rau hauv cov yeeb nkab network feem ntau yog qhib thiab kaw infrequently, cov packing yuav tsum tsis muaj zog rau ob peb xyoos, thiab cov packing tsis laus, thiaj li yuav tswj tau lub sealing nyhuv rau lub sij hawm ntev;

② Valve ncej packing yuav tsum dais nquag qhib thiab kaw, zoo sealing nyhuv;

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 qhov ntim yuav tsum tau hloov pauv, lub pneumatic valve tsim yuav tsum xav txog qhov hloov ntsuas raws li qhov dej siab.
