(热静力)进口膜盒式蒸汽疏水阀 主要性能 Main performance

热静力膜盒式蒸汽疏水阀内膜盒是用特殊材质制造的感温元件，靠感温液体的状态转变来控制阀的开启和关闭，耐压强度高，抗水击能力强，对温度的敏感性好，因此动作灵敏，排量大  RETZ  inner membrane box of the thermostatic diaphragm steam trap is a temperature sensing element made of special materials. It controls the opening and closing of the valve by the state change of the temperature sensing liquid. It has high pressure resistance, strong water hammer resistance and good sensitivity to temperature. Therefore, it has sensitive action and large displacement

(热静力)进口膜盒式蒸汽疏水阀 特点∶ Performance characteristics

排空气性能优良，不会造成冻结，防水击、耐过热、可任意角度安装 Excellent air exhaust performance, no freezing, waterproof, heat resistant, can be installed at any angle

通汽初始，阀门全部开启，低温凝结水和空气迅速排出，缩短了设备启动时间 RETZ At the beginning of steam supply, all valves are opened, and low-temperature condensate and air are quickly discharged, which shortens the start-up time of the equipment

能在低于饱和温度较多的情况下排放凝结水，节能效果显  It can discharge the condensed water when the temperature is much lower than the saturation temperature, and the energy saving effect is obvious

阀腔内设有不锈钢过滤网，维护保养简单 The valve chamber is equipped with stainless steel filter screen, which is easy to maintain

钴铬钨合金阀座耐磨、耐腐，并在关闭时无撞击，稳定性好  Cobalt chromium tungsten alloy valve seat is wear-resistant, corrosion-resistant, and has good stability without impact when closing

安装示意图 Installation diagram

请按阀体上流向箭头所示安装，注意疏水阀处于水平位置或低于设备出口，以保证正常疏水 RETZ Please install as shown by the flow arrow on the valve body. Note that the drain valve is at the horizontal position or lower than the equipment outlet to ensure normal drainage
