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，要在被排放设备和疏水阀之间安装一个真空破坏器。如果从疏水阀到回水管不是使用重力排放，疏水阀和排放管线就应该用人工排放或者使用带防冻措施的排放管自动排放。还有，当多个疏水阀一起安装在疏水阀站的时候，给疏水阀保温可以防止冰冻。

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.

防冻措施有:

Anti freezing measures include:

1.疏水阀不要选的尺寸过大。

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

3.向下倾斜疏水阀排放管线，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.疏水阀排放管线和凝结水回水管线加保温。

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

5.当凝结水回水管线暴露在大气条件下时，应考虑加伴热管。

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，垂直排放管要与回水集管上部的排放管相邻，并把排放管和疏水阀排放管一起保温上海良工阀门厂家介绍的以上的内容对大家是有帮助的。如果大家还想知道更多的信息，那就请继续等待良工阀门小编的分享吧！

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.
