Ordinary spring loaded pressure relieve valves which open at a predetermined pressure are of no use in relieving the high surge pressures encountered during in water hammer. The main reasons are which they are considered to be extremely slow in opening and they close down when they encounter a negative pressure. The water hammer surge features a set of quickly alternating waves of very increased pressure and low pressure. To counter the water hammer surge what we need functions as a device that releases quickly and sucks in introduce air into the pipeline but does not allow this air to escape on encountering a positive pressure wave. The slow closing provides assurance that the subsequent positive pressure waves are damped by the action of the entrapped air. In our air cushion valve, The quick opening is attained via an air intake with a spring mechanism port. The spring is specifically crafted for open at a preset pressure differential. The slow closing is achieved by using an orifice to Release the air at a controlled pressure and rate. The orifice effectively behaves like a pneumatic damper. By modifying the setting of we can, The orifice control the outflow rate of air extracted from the valve. All moving parts shafts, Bushes and stoppers and the entire needle orifice are made constructed with top-quality-quality stainless steel. The rest pertaining to the physique is a modular mild steel fabrication. The modular layout facilitates easy maintenance.
