Masharti ya kufuta valves pampu

Kuna pointi tatu za kusajiliwa katika mchakato wa kurekebisha udhibiti naVipu valve.
one, the regulating and Vipu valve 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 Vipu valve 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.

Mbili, valve ya kudhibiti ni nzito sana, shimo la shimo ni ndogo na muundo ni ngumu. (kwa mfano, kudhibiti shinikizo na kudhibiti valve ya DN1800 hadi 28T, kama vile matawi na plastiki, kama vile matawi na plastiki katika maji ya bomba, ni rahisi kuingia kwenye cavity na shimo la valve. manhole kutekeleza matengenezo ya jumla, kuondoa sundries, na kutatua tatizo la urekebishaji baada ya kuvunja shinikizo la kusimamia na kusimamia valve Ili uweze kuchunguza na kupuuzwa, valves 1 kipepeo inapaswa kuweka mbele ya valve na baada ya valve (manhole huwekwa kati ya valve kipepeo na valve ya kudhibiti shinikizo) ili kukata maji katika mabomba ya chini na ya chini. Ili kuhakikisha mtiririko wa maji imara na kuepuka valve ya kipepeo ya cavitation, umbali kati ya shinikizo la kusimamia na kudhibiti valve na valve kipepeo lazima kufikia mahitaji ya urefu moja kwa moja bomba kabla na baada ya valve.
Tatu, kiwango cha ufunguzi wa shinikizo la kudhibiti kipepeo la kipepeo inahitaji kuhamishiwa kwenye chumba cha kudhibiti na sensor (mbele ya valve, baada ya valve na mtiririko), na chumba cha kudhibiti kinadhibitiwa na chumba cha kudhibiti. Ili kupata ishara imara, mtiririko wa valves ya mbele na ya nyuma ya valve inahitajika kuwa imara. Kwa ujumla, urefu wa bomba ni mara 35 urefu wa bomba moja kwa moja, na baada ya valve husababisha mtiririko kuzalisha nishati ya swirling, Bubbles nyingi kupasuka hutengenezwa katika bomba, na urefu wa urefu wa bomba moja kwa moja sio chini ya mara 5 urefu wa bomba.
