產品介紹
一、結構及用途 Structure and purpose
該閥主要用于管路系統中，以防止管路系統超壓或維持管路的壓力，當泵關閉后還可以減少水錘沖擊。也可用于大型供水系統的水錘消除裝置，并且閥門控制系統的進口處裝有一個自清洗濾網，利用流體特性，使比重較大、直徑較大的懸浮顆粒不會進入控制系統，確保主閥的上游供水壓力某一設定值上使系統循環暢通無阻，該閥起閉靈敏、安全可靠、動作平穩、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.
