Special check valve for ammonia | Check valve for cast steel ammonia | H44B check valve for ammonia

/Special check valve for ammonia
It is designed and manufactured strictly in accordance with the standards of valves for ammonia. The sealing surface is made of Babbitt alloy or PTFE, which has a small friction coefficient, good wear resistance, flexible and reliable action, and excellent sealing performance. The valve disc moves up and down along the center position. The special check valve for ammonia gas is suitable for ammonia gas or liquid ammonia pipelines to prevent the backflow of the medium.
Ammonia-specific check valves can be divided into ammonia-specific check valves, ammonia-specific check valves, and ammonia-specific check valves according to their structural methods.

Working principle of ammonia check valve
When the straight-through ammonia check valve is used, the working pressure of the medium pushes the valve disc open, and the valve disc rotates around the axis of the valve body. At this time, the valve disc opens, and the medium When closing, relying on the counterflow of the medium and the self-weight of the valve disc, the valve disc rotates around the rotating axis in the valve body, so that the valve disc and the valve seat are closely connected to achieve the purpose of closing. Once closed, its sealing force is formed. This sealing force is the force of the reverse medium pressure acting on the valve disc. The sealing specific pressure is also formed, which can ensure the valve sealing. The higher the working pressure of the reverse medium in the pipeline, the greater the sealing force, the greater the sealing specific pressure, and the easier it is to ensure sealing.
