Introduction to valves: how to prevent freezing protection of traps, Xinjiang valve knowledge hall: selection and installation of appropriate traps. As long as steam passes through, there will be no freezing problem. However, if the steam is cut off, the steam condensate will form a vacuum in the heat exchanger or companion pipe. This will prevent condensate from being discharged freely from the system before freezing occurs.

所以，要在被排放設備和疏水閥之間安裝一個真空破壞器。如果從疏水閥到回水管不是使用重力排放，疏水閥和排放管線就應該用人工排放或者使用帶防凍措施的排放管自動排放。還有，當多個疏水閥一起安裝在疏水閥站的時候，給疏水閥保溫可以防止冰凍。

Therefore, a vacuum breaker should be installed between the discharged equipment and the drain valve. If gravity discharge is not used from the drain valve to the return pipe, the drain valve and discharge pipeline should be discharged manually or automatically with a discharge pipe with anti freezing measures. In addition, when multiple steam traps are installed in the steam trap station together, keeping the steam trap warm can prevent freezing.

防凍措施有:

Anti freezing measures include:

1.疏水閥不要選的尺寸過大。

1. The size of drain valve shall not be too large.

3.向下傾斜疏水閥排放管線，以加快重力排放的速度。

3. Tilt the drain valve discharge pipeline downward to speed up the gravity discharge.

4.疏水閥排放管線和凝結(jié)水回水管線加保溫。

4. Steam trap discharge pipeline and condensate return pipeline shall be insulated.

5.當凝結(jié)水回水管線暴露在大氣條件下時，應考慮加伴熱管。

5. When the condensate return pipeline is exposed to atmospheric conditions, heat tracing pipe shall be considered.

6.如果回水管升高，垂直排放管要與回水集管上部的排放管相鄰，并把排放管和疏水閥排放管一起保溫上海良工閥門廠家介紹的以上的內(nèi)容對大家是有幫助的。如果大家還想知道更多的信息，那就請繼續(xù)等待良工閥門小編的分享吧！

6. If the return pipe rises, the vertical discharge pipe shall be adjacent to the discharge pipe at the upper part of the return header, and the discharge pipe and drain valve discharge pipe shall be insulated together.
