結(jié)構(gòu)及用途 Structure
and purpose
該閥主要用于管路系統(tǒng)中，以防止管路系統(tǒng)超壓或維持管路的壓力，當(dāng)泵關(guān)閉后還可以減少水錘沖擊。也可用于大型供水系統(tǒng)的水錘消除裝置，并且閥門控制系統(tǒng)的進(jìn)口處裝有一個(gè)自清洗濾網(wǎng)，利用流體特性，使比重較大、直徑較大的懸浮顆粒不會(huì)進(jìn)入控制系統(tǒng)，確保主閥的上游供水壓力某一設(shè)定值上使系統(tǒng)循環(huán)暢通無阻，該閥起閉靈敏、安全可靠、動(dòng)作平穩(wěn)、使用壽命長。
Use in a pipeline system to prevent it from surpassing
pressure or keep the pressure of it．to reduce the water
hammer＇s shock after the pump is closed and also and also
used as a water hammer remover for a large water supply
system．On the inlet of the valve＇s control system a self
cleaning filter screen is placed，which，by means of the
bigger specific gravity of the fluid，stops the suspension
grains of a bigger specific gravity and diameter going into
the sys-tern to ensure the main valve＇s water supply
pressure at the upstream at a set value to get the system
smoothly circulated without any resistance．This valve
features sensitive open-close，safety，reliability，stable
motion and long duration. |
