[0002] A pressure regulating valve is an automated control device used to control parameters such as fluid flow rate, pressure, temperature, or liquid level. It adjusts the flow rate or pressure of the fluid by changing the flow area of the fluid to meet the requirements of the process. Pressure regulating valves are widely used in industrial automation, chemical, petroleum, power, and metallurgical fields.
[0003] Pressure regulating valves are needed in sewage treatment. However, when the sewage flow is too large, the pressure inside the traditional pressure regulating valve becomes too high, which can damage the valve. Traditional pressure regulating valves cannot cope well with large amounts of sewage. Summary of the Invention

[0009] In addition, a preferred structure is that each of the two sides of the bottom end of the baffle is provided with a slider, and the slider slides within the groove.
[0010] Furthermore, in a preferred configuration, the adjusting mechanism includes a second connecting rod, a baffle plate fixedly mounted on the top of the second connecting rod, a second spring fixedly mounted on the top of the baffle plate, and the top of the second spring fixedly connected to the top of the inner wall of the pressure regulating body.
[0011] In addition, a preferred structure is that a stop is provided at the bottom of the second connecting rod, and the stop is located in the body of the pressure regulating valve.
[0012] In addition, a preferred structure is that the pressure regulator body has two grooves on both sides of its inner wall.
[0013] In addition, a preferred structure is that sliders 2 are provided on both sides of the baffle, and sliders 2 slide within the groove 2.
[0014] The beneficial effects of this utility model are as follows:
[0015] In this invention, by adding a pressure relief mechanism, when there is too much sewage, the baffle of the pressure relief mechanism will move down, so that a part of the sewage in the valve body of the pressure regulating valve flows to a designated location through the return pipe, which effectively protects the pressure regulating valve, facilitates automatic pressure adjustment of the pressure regulating valve, and makes it easy to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6An automatic pressure regulating valve for sewage treatment includes a pressure regulating valve body 1, with an inlet pipe 2 and a drain pipe 3 fixedly installed at both ends of the pressure regulating valve body 1, a pressure regulating body 6 at the top of the pressure regulating valve body 1, a pressure relief body 4 at the bottom of the pressure regulating valve body 1, an adjustment mechanism 7 inside the pressure regulating body 6, a pressure relief mechanism 8 inside the pressure relief body 4, and a return pipe 5 at one end of the pressure relief body 4.
[0025] The pressure relief mechanism 8 includes a connecting rod 81, which slides inside the pressure relief body 4. A baffle 83 is provided on the top of the connecting rod 81, and a spring 82 is provided on the outer sleeve of the connecting rod 81. The two ends of the spring 82 are fixedly connected to the bottom of the baffle 83 and the bottom of the inner wall of the pressure relief body 4, respectively.
[0026] Meanwhile, sliding grooves 41 are provided on both sides of the inner wall of the pressure relief body 4.
[0027] Furthermore, sliders 831 are provided on both sides of the bottom end of the baffle 83. The sliders 831 slide within the groove 41, making the up-and-down movement of the baffle 83 more stable.
[0028] Meanwhile, the adjusting mechanism 7 includes a connecting rod 73, a baffle 72 is fixedly installed on the top of the connecting rod 73, a spring 71 is fixedly installed on the top of the baffle 72, and the top of the spring 71 is fixedly connected to the top of the inner wall of the pressure regulating body 6.
[0029] Meanwhile, a stop 74 is provided at the bottom of the connecting rod 73. The stop 74 is located inside the pressure regulating valve body 1. When the stop 74 moves up and down, the connecting rod 73 will also move synchronously and enter the compression spring 71.
[0030] Meanwhile, sliding grooves 61 are provided on both sides of the inner wall of the pressure regulating body 6.
[0031] Furthermore, sliders 721 are provided on both sides of the baffle 72. The sliders 721 slide within the groove 61, making the up-and-down movement of the baffle 72 more stable.
[0032] In this embodiment, the inlet pipe 2 and the drain pipe 3 of the pressure regulating valve are connected to the external pipe in sequence, and then connected to the return pipe 5 with a pipe. When sewage enters the valve body 1 of the pressure regulating valve through the inlet pipe 2, when the sewage volume is sufficient, the sewage squeeze block 74 moves upward, and the baffle 72 also moves upward synchronously, squeezing the spring 71. A gap will be generated between the baffle 74 and the valve body 1 of the pressure regulating valve, and the sewage flows to the drain pipe 3 through the gap.
[0033] When the amount of sewage is too large, the baffle 74 is squeezed to the upper end of the regulating body 6. At this time, the pressure inside the pressure regulating valve body 1 is too high, and the sewage will squeeze the baffle 83. The baffle 83 moves downward in the pressure relief body 4, and some sewage will flow out to the designated location through the return pipe 5 to relieve the pressure inside the pressure regulating valve body 1. When the sewage pressure inside the pressure regulating valve body 1 decreases to the normal value, the baffle 72 will be reset under the elastic action of the spring 82, and the sewage will flow normally.
[0034] In this utility model, by adding a pressure relief mechanism 8, when there is too much sewage, the baffle 83 of the pressure relief mechanism 8 will move down, so that a part of the sewage in the valve body 1 of the pressure regulating valve flows to the designated location through the return pipe 5, which protects the pressure regulating valve well, facilitates the automatic pressure adjustment of the pressure regulating valve, and is easy to use.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
