Cov teeb meem xav tau kev saib xyuas thiab lub sijhawm ntawm pneumatic kaw-off valve

Pneumatic kaw-off valve yog ib tug tshiab kev ruaj ntseg pab txhawb nqa rau roj pipeline engineering, uas yog feem ntau txuas nrog combustible gas to monitoring instrument. Thaum lub ntsuas hluav taws xob pom cov pa tawm ntawm cov hluav taws xob tsis zoo ntawm cov hluav taws xob hluav taws xob nres valve, nws cia li kaw thiab kaw lub ntsiab roj valve, txiav tawm cov pa roj, thiab ua kom lub sijhawm nres qhov tshwm sim ntawm cov xwm txheej phem; Txuas nrog qhov txwv qhov ntsuas kub (siab) kev nyab xeeb ntawm cov khoom siv thermal, thaum qhov kub thiab txias (siab) ntawm qhov ntsuas qhov ntsuas hauv cov khoom siv ntau tshaj li qhov kev txwv tsis pub dhau, lub valve valve yuav raug txiav thiab ceev ceev kom nres cov roj; Txuas nrog lub tswb hluav taws xob hauv nruab nrab ntawm cov tsev siab siab, thaum lub tsev nyob hauv hluav taws, cov khoom siv roj hauv lub tsev yuav raug txiav tawm kom tsis txhob muaj cov pa tawg; ZCR roj av thaum muaj xwm ceev kaw lub valve yog teem rau hauv lub gas mov network ntawm lub nroog los yog lub Hoobkas, uas muaj peev xwm tswj tau nyob rau hauv lub hauv paus tswj chav tsev thiab lub pipeline gas mov nyob rau hauv qhov chaw raug xwm txheej yuav raug kaw remotely thiab remotely.

Pneumatic kaw-off valve yog ib qho ntawm cov actuator hauv automation system, uas tuaj yeem siv dav hauv roj av, tshuaj lom neeg, metallurgical thiab lwm qhov chaw tsim khoom lag luam. Cov cua qhov chaw ntawm pneumatic kaw-off valve yuav tsum tau lim compressed cua. Qhov nruab nrab ntws los ntawm lub valve lub cev yuav tsum yog kua thiab roj yam tsis muaj impurities thiab hais.

Kev ceev faj rau kev siv pneumatic kaw-off valve:

1. lub pneumatic kaw-off valve yog nyob rau hauv ib txwm qhib lub xeev nyob rau hauv kev ua hauj lwm txhua hnub, thiab solenoid valve coil nyob rau hauv lub hwj chim tawm lub xeev, thiab tsis siv hluav taws xob lub zog.

2. Thaum muaj xwm txheej tshwm sim, lub valve coil ntawm pneumatic kaw-off valve yog powered ntawm lub sijhawm, ua rau lub valve kaw sai thiab nkag mus rau hauv lub xeev ntawm tus kheej. Nyob rau lub sijhawm no, txawm tias lub hwj chim muab tshem tawm, lub pneumatic kaw-off valve tseem nyob rau hauv tus kheej-locking lub xeev thiab yuav tsis qhib tau rov qab.

3. lub pneumatic kaw-off valve txais kev tsav valve disc, uas yog ib qho yooj yim qhib. Txawm hais tias lub siab ncav cuag 6bar, nws yooj yim heev rau qhib. Txoj kab uas hla yog loj dua DN125. Lever kov yog saws los ua kom lub valve ncav cuag lub zog hloov pauv thiab ceev ceev.

4. Thaum cov neeg ua haujlwm tau ua tiav qhov kev sib tsoo, lub valve yuav qhib manually ua ntej cov khoom cua tuaj yeem rov qab los.
