Abstract

The invention relates to a water hammer retarding assembly which comprises a diaphragm and a diaphragm frame. The diaphragm frame comprises a base part arranged at one side of the diaphragm, a flow guide part and a protruding part are formed on the base part and penetrate through the diaphragm to be arranged at the other side of the diaphragm, the upper end of the protruding part is a circular truncated cone, the bottom end of the protruding part is a cylinder, a plurality of tangent planes which are arranged at equal angles and longitudinally span the circular truncated cone and the cylinder are formed on the periphery of the protruding part, the surfaces of the tangent planes are arc-shaped tangent planes, the tangent planes comprise upper tangent planes located on the circular truncated cone and lower tangent planes located on the cylinder, complete sealing faces are formed between the lower tangent planes and the bottom face of the cylinder, and tangent plane grooves are formed in the tangent planes; and spacing surfaces are formed between the adjacent tangent planes and are positioned on the circular truncated cone, and spacing grooves are formed in the spacing surfaces. According to the water hammer retarding assembly, the cambered tangent plane structure and the step-by-step water hammer retarding structure on the protruding part are utilized, so that water hammers generated in the closing process of a water valve are greatly reduced, and the service life of an electromagnetic valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of electromagnetic valves, in particular to a water hammer mitigation assembly and an electromagnetic valve thereof. Background technique [0002] The water hammer effect refers to a serious water hammer caused by the water flow hitting the pipeline when the feed water pump starts and stops. When the open water valve is suddenly closed or the feed water pump is suddenly stopped, the water flow will generate a pressure on the water valve and the pipe wall, mainly the water valve or the pump. The instantaneous pressure generated by the water hammer can reach dozens or even hundreds of times of the normal working pressure in the pipeline. Such large pressure fluctuations can cause strong vibration and noise in the pipeline system, and may damage the water valve joints. Has a great destructive effect. Therefore, the water hammer effect is extremely destructive: if the pressure is too high, it will cause the ru...
