用途 User 用于高層建筑或其它供水系統(tǒng)的水泵出口,可以防止介質(zhì)倒流,而且可以減小水錘現(xiàn)象,以達(dá)到安全及安靜的效果。 Water pump outlet for high-rise buildings or other water supply systems can prevent backflow of the medium and can reduce water hammer phenomenon to achieve safe and quiet effect. 可防止水錘和水擊現(xiàn)象的產(chǎn)生,達(dá)到緩閉消聲的效果。是能夠調(diào)控啟閉速度的止回閥,在水泵啟動或停止運行時,可現(xiàn)場調(diào)節(jié)至開啟或關(guān)閉速度。 Water hammer and water hammer can be prevented to achieve the effect of slow - closing. It is the check valve that can control the opening and closing speed and can be adjusted to the best opening or closing speed when the pump starts or stops running. 停泵后,介質(zhì)倒流,閥門上腔壓力大于下腔壓力,閥瓣下落關(guān)閉。而控制回水進(jìn)入膜片上腔的速度,就可以調(diào)整閥門的關(guān)閉速度,從而達(dá)到緩閉的目的。 After stopping the pump, the flow of the medium is inverted, the pressure of the chamber pressure is greater than that of the lower chamber, and the valve is closed.Controlling the speed of the return water to the cavity of the diaphragm can adjust the closing speed of the valve to achieve the purpose of slow closure. 執(zhí)行標(biāo)準(zhǔn) Executive standard 法蘭尺寸 Flange dimensions:GB/T 17241.6 試驗檢驗 Test test:GB/T 13927 安裝圖典型 Installation diagram
