Zinthu zowonjezera ma valves amphamvu

Pali mfundo zitatu zomwe ziyenera kulembedwa pokhazikitsa ndondomeko yowonjezerekaMphuphu yamapope.
one, the regulating and Mphuphu yamapope are arranged in a combined way, leaving one valve to reserve several other valves in parallel. The number and type of the shut-off valve after parallel connection are determined, and the circulation capacity is up to Cv standard. In order to ensure the non overflow of the pressure Mphuphu yamapope operation, the pressure stabilizing tower should be set up to make the hydrostatic pressure of the water supply system close to the working pressure of the pipe as much as possible to reduce the cost of the project. If the pressure stabilizing tower is set up in the upstream of the pressure regulating and regulating valve, it is sure that the height of the pressure stabilizing tower is higher than the water level of the water inlet. Generally, the height of the pressure stabilizing tower is higher, the investment of the project is increased, and the operation is not convenient, so the pressure regulating and reducing valve is set in the downstream of the stabilizing tower.

Zili ziwiri, valavu yoyendetsa ndi yolemetsa kwambiri, chimbudzi chimakhala chaching'ono ndipo mawonekedwe ake ndi ovuta. (mwachitsanzo, kupanikizika ndi dalaivala ya DN1800 ndi 28T, monga nthambi ndi mapulastiki, monga nthambi ndi mapulasitiki mu madzi a pomba, ndi zosavuta kulowetsa pamphuno ndi kutuluka. Manhole kuti asamalidwe bwino, chotsani sundries, ndi kuthetseratu vuto la kupopera mutatha kuthana ndi kupanikizika ndi kupanikizika. Kuti muthe kufufuzidwa ndi kupanikizidwa, valvegufe 1 agwiritsidwe patsogolo pa valve ndi pambuyo valve (chombocho chimakhazikitsidwa pakati pa magulugufe a agulugufe ndi valve yosamalitsa) kuti athetse madzi m'mphepete mwa kumtunda ndi kumunsi. Kuti muonetsetse kuti madzi akuyenda bwino komanso kupewa valavu ya butterfly, mtunda pakati pa magetsi olamulira ndi olamulira ndipo valvegufe amagwiritsira ntchito chofunikira cha kutalika kwa chitoliro chisanafike ndi pambuyo pake.
Zitatu, chiyeso choyambirira cha kupanikizika kwa magulugufe a butterfly chiyenera kutumizidwa ku chipinda cholamulira ndi sensa (kutsogolo kwa valve, pambuyo pa valavu ndi kutuluka), ndipo chipinda cholamulira chimayang'aniridwa ndi chipinda cholamulira. Kuti mupeze chizindikiro chokhazikika, kuthamanga kwa kutsogolo kutsogolo ndi kumbuyo kwa valve kumayenera kukhazikika. Kawirikawiri, kutalika kwa chitoliro kumakhala kutalika kwa katatu kwa bomba lolunjika, ndipo pambuyo pa valavu imayambitsa kuyendayenda kuti ipange mphamvu zowonongeka, ming'oma yochulukirapo imapangidwira mu chitoliro, ndi kutalika kwa kutalika kwa chitoliro sikunali nthawi zosachepera 5 kutalika kwa chitoliro. Degree.
