The water flow pressure stabilizer for the drip irrigation system utilizes the guide cylinder in the main body to be matched with the piston core, when the water pressure exceeds the specified pressure, the water pressure higher than the inside of the piston core pushes the piston core to move leftwards, so that the piston water inlet hole and the main body water inlet hole are staggered to be closed, when the inside of the piston core reaches the specified water pressure, the spring pushes the piston core to reset under the action of restoring force, so that water flow is conducted again, the internal structure of the flow stabilizer is protected from being damaged, and the purpose of stabilizing the pressure is achieved.
The invention is used for a water flow pressure stabilizer of a drip irrigation system, and a sealing gasket is arranged between the inner wall of the right joint and the water outlet joint. The sealing performance of the right joint of the main body, the water outlet joint and the convex ring end part of the piston core is improved. The outer walls of the piston core and the convex ring are respectively provided with a sealing groove and an oil sealing groove, and a sealing ring is arranged in the sealing groove. The sealing ring is arranged, the tightness between the piston core and the guide cylinder and the tightness between the convex ring and the inner wall of the main body are improved, and the oil sealing groove is arranged, and lubricating oil is added into the oil sealing groove, so that the left and right movement of the piston core and the convex ring can be lubricated, and the smooth action of the piston core and the convex ring can be ensured. The left side inner wall of the main body water inlet hole is provided with a main body water sealing step, the right side inner wall of the piston water inlet hole is provided with a piston water sealing step, and the main body water sealing step is matched with the piston water sealing step after the piston core moves to the left under high pressure. If the water pressure is too high to push the piston core to move leftwards, when the piston water sealing step is blocked with the main water sealing step, water flow cannot enter the water outlet pipe through the piston core and the water outlet joint, so that the purpose of sealing water at high pressure is further improved.
