Description

Automatic pressure regulating valve for sewage treatment Technical Field The utility model relates to the technical field of sewage treatment, in particular to an automatic pressure regulating valve for sewage treatment. Background During sewage treatment, there is often fluctuations in the flow and pressure of sewage, especially in municipal systems employing multiple users of common sewage networks or rain and sewage confluences, where the drainage pressure can vary significantly over time. In the prior art, an electric control valve or a manual adjusting device is often adopted to control the water inflow. In the prior art, a passive flow limiting device, such as a flow limiting orifice plate or a check valve, is adopted, but the adjusting capability is limited, the flow area cannot be automatically adjusted according to the water pressure, and the problem of overlarge water flow impact during high pressure can be caused. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model provides an automatic pressure regulating valve for sewage treatment. In order to achieve the above object, the technical scheme of the present utility model is as follows: an automatic pressure regulating valve for sewage treatment, comprising: A water pipe for transporting sewage; The adjusting plate is inserted into the water pipe in a penetrating way, is arranged obliquely upwards along the water flow direction and can slide along the oblique direction, the adjusting plate is used for limiting the water flow to pass, and a small gap is kept between the bottom of the adjusting plate and the inner side wall of the water pipe in the initial stage; The impact plate is vertically fixed on the upstream surface of the adjusting plate, and the length direction of the impact plate is vertical to the water flow direction; One end of the spring is fixed on the back surface of the impact plate and is used for extruding the impact plate towards the direction of the water pipe along the length direction of the adjusting plate; When the pressure of water in the water pipe is increased, the water applies acting force to the impact plate, the impact plate and the adjusting plate are pressed to move along the length direction of the adjusting plate in the direction away from the water pipe, and the gap between the adjusting plate and the inner wall of the water pipe is increased. Preferably, the angle formed by the adjusting plate and the water flow direction is 20-40 degrees. Preferably, the method further comprises: and the screw rod is connected with the water pipe in a threaded manner, is connected with the other end of the spring and is used for extruding the spring. Preferably, the water pipe inner wall is located at two sides of the adjusting plate and is fixedly provided with a baffle plate matched with the adjusting plate to plug the water pipe inner wall.
