3. Kuchepetsa kupanikizikavalavunjira yoyesera kuthamanga

① Mayesero amphamvu a valve yochepetsera kuthamanga nthawi zambiri amasonkhanitsidwa pambuyo pa mayeso amodzi, ndipo amathanso kusonkhanitsidwa pambuyo pa mayeso.Kutalika kwa kuyesa mphamvu: 1min ndi DN<50mm;DN65 ~ 150mm yaitali kuposa 2min;Ngati DN ndi yayikulu kuposa 150mm, ndi yayitali kuposa mphindi zitatu.Pambuyo pa mvuvuzi zimatenthedwa ndi zigawozo, nthawi 1.5 kupanikizika kwakukulu pambuyo poti valavu yochepetsera mphamvu ikugwiritsidwa ntchito, ndipo kuyesa mphamvu kumachitika ndi mpweya.
② Kuyesa kolimba kumachitika molingana ndi sing'anga yeniyeni yogwirira ntchito.Poyesa ndi mpweya kapena madzi, mayeserowa amachitika pa 1.1 nthawi yamphamvu mwadzina;Poyesa ndi nthunzi, imachitika pamphamvu yovomerezeka yogwira ntchito pa kutentha kwa ntchito.Kusiyana pakati pa kukakamiza kolowera ndi kutulutsa kotulutsa sikuyenera kukhala kochepera 0.2MPa.Njira yoyesera ili motere: pambuyo pa kulowetsedwa kwa inlet kusinthidwa, chowongolera chowongolera cha valavu chimasinthidwa pang'onopang'ono kuti chiwongolero chotuluka chisasunthike mosalekeza ndikusinthidwa mosalekeza mkati mwamlingo wapamwamba komanso wocheperako wamtengo wapatali, popanda kuyimirira ndi kutsekeka.Kwa valve yochepetsera kuthamanga kwa nthunzi, pamene kulowetsedwa kumachotsedwa, valavu imatsekedwa ndiyeno valavu imadulidwa, ndipo kuthamanga kwa kutuluka ndipamwamba kwambiri komanso mtengo wotsika kwambiri.Pakadutsa mphindi 2, chiyamikiro cha kutulutsa kotulutsa kuyenera kugwirizana ndi zomwe zaperekedwa.Kwa ma valve ochepetsera madzi ndi mpweya, mphamvu yolowera ikasinthidwa ndipo kutulutsa kotulutsa ndi zero, valavu yochepetsera mphamvu imatsekedwa kuti iyesedwe kusindikiza, ndipo palibe kutayikira mkati mwa mphindi ziwiri ndikoyenera.

4. Valve ya butterflynjira yoyesera kuthamanga

Mayesero amphamvu a valavu ya butterfly ya pneumatic ndi yofanana ndi ya valve ya globe.Mayeso osindikizira a gulugufe ayenera kuwonetsa sing'anga yoyesera kuchokera kumapeto kwa inflow, mbale ya butterfly iyenera kutsegulidwa, mapeto ena ayenera kutsekedwa, ndipo kuthamanga kwa jekeseni kuyenera kufika pamtengo wotchulidwa;Pambuyo poona kuti palibe kutayikira mu kulongedza ndi zisindikizo zina, tsekani mbale ya gulugufe, tsegulani mbali ina, ndipo fufuzani kuti palibe kutayikira mu chisindikizo cha gulugufe.Mavavu agulugufe omwe amagwiritsidwa ntchito poyendetsa kayendedwe kake sayesa kusindikiza.

5.Pulagi valvenjira yoyesera kuthamanga
① Valovu ya pulagi ikayesedwa kuti ikhale yamphamvu, sing'angayo imayambitsidwa kuchokera kumapeto, njira yonseyo imatsekedwa, ndipo pulagi imazunguliridwa pamalo otseguka kuti ayesedwe, ndipo thupi la valve silipezeka kuti likutuluka.
② Pakuyesa kusindikiza, tambala wowongoka ayenera kusunga kupanikizika mumtsempha wofanana ndi ndimeyi, kutembenuza pulagi kumalo otsekedwa, kuyang'ana kuchokera kumapeto kwina, ndiyeno tembenuzani pulagi 180 ° kuti mubwereze mayeso omwe ali pamwambawa;Valve yanjira zitatu kapena zinayi iyenera kusunga kupanikizika kwapabowo kofanana ndi mbali imodzi ya ndimeyi, kutembenuza pulagi kumalo otsekedwa, kuwonetsa kupanikizika kuchokera kumapeto kwa Angle, ndikuyang'ana kumapeto kwina. nthawi yomweyo.
Asanayambe kuyezetsa valavu ya pulagi, amaloledwa kugwiritsa ntchito wosanjikiza wosanjikiza mafuta opaka mafuta osakaniza osakhala acidic pamalo osindikizira, ndipo palibe kutayikira ndi madontho owonjezera amadzi omwe amapezeka mkati mwa nthawi yodziwika.Nthawi yoyesera ya valavu ya pulagi ikhoza kukhala yayifupi, yomwe imatchulidwa kuti l ~ 3min malinga ndi m'mimba mwake.
Vavu ya pulagi ya gasi iyenera kuyesedwa ngati kulimba kwa mpweya kumawirikiza 1.25 kukakamiza kugwira ntchito.

6.Valavu ya diaphragmnjira yoyesera kuthamanga

Kuyesa kwamphamvu kwa ma valve a diaphragm kumayambitsa sing'anga kuchokera kumalekezero onse, kumatsegula diski ya valve, ndikutseka mbali inayo.Pambuyo pa kukakamizidwa kwa mayeso kukwera ku mtengo wotchulidwa, ndi woyenerera kuti awone kuti thupi la valve ndi chivundikiro cha valve sichikutuluka.Kenako chepetsani kupanikizika kwa kukakamiza koyeserera, kutseka chimbale cha valve, tsegulani mbali ina kuti muwunikenso, palibe kutayikira komwe kuli koyenera.

7.Vavu yoyimitsandivalve throttlenjira yoyesera kuthamanga
Kuyeza kwamphamvu kwa valavu yapadziko lonse lapansi ndi valavu ya throttle nthawi zambiri kumayika valavu yosonkhanitsidwa muzitsulo zoyesa kuthamanga, kutsegula diski ya valve, kubaya sing'anga mpaka mtengo wotchulidwa, ndikuwona ngati thupi la valve ndi chivundikiro cha valve chikutuluka thukuta ndi kutuluka.Mayeso a mphamvu angathenso kuchitidwa payekha.Mayeso olimba ndi a valve yoyimitsa yokha.Pakuyesa, tsinde la valve yoyimitsa ili pamtunda, diski ya valve imatsegulidwa, sing'anga imayambitsidwa kuchokera kumapeto kwa valve disc mpaka mtengo wotchulidwa, ndipo kulongedza ndi gasket kumafufuzidwa.Mukayenerera, tsekani chimbale cha valve ndikutsegula mbali ina kuti muwone ngati pali kutayikira.Ngati kuyesedwa kwa mphamvu ya valve ndi kulimba kumayenera kuchitidwa, kuyesa mphamvu kungathe kuchitidwa poyamba, ndiyeno kupanikizika kumachepetsedwa kumtengo wodziwika wa kuyesa kolimba, ndipo kulongedza ndi gasket kumafufuzidwa.Kenako tsekani chimbale cha valve, tsegulani chotulukapo kuti muwone ngati kutayikira kosindikiza kwatsikirako.
