[0002] The sewage pipe pressure regulating device is a device used to adjust the pressure in the sewage pipe system. During the sewage treatment process, excessive or low pressure may appear in the pipe system, which will affect the normal operation of the pipe system and even cause the pipe to rupture or leak.

[0003] Existing sewage pipe pressure regulating devices are usually composed of pressure sensors, controllers and actuators. When the pressure in the pipeline system exceeds the set range, the pressure sensor will detect this situation and transmit a signal to the controller. The controller adjusts the opening degree of the valve or pump in the pipeline system through the actuator based on the received signal, thereby achieving pressure regulation.

[0004] In actual use, the existing sewage pipe regulating device has a complex structure, requires the cooperation of sensors, controllers and actuators, has low pressure relief efficiency, and results in high subsequent maintenance and repair costs. Utility Model Content

[0015] The connecting rod passes through the pressure component and the pressure relief component, one end of which is pressed on one side of the pressure relief component, and the other end of which is fixed on the side of the fixed component away from the pressure relief component through a locking nut.

[0016] Furthermore, a plurality of drain grooves are provided inside the pressure relief component, and the pressure relief grooves are communicated with the drain grooves.

[0017] Furthermore, sealing members are provided at the connection between the pressure relief member and the pressure member, and at the connection between the fixing member and the pressure member.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] By providing a pressure component, a certain pressure can be generated between the pressure relief component and the fixed component, so that the sewage in the sewage pipe can have a certain pressure and the sewage can penetrate out of the pipe. At the same time, a pressure relief groove is provided on the inner wall of the pressure relief component, and a pressure relief key is provided on the corresponding fixed component. The pressure relief groove and the pressure relief key are fixedly connected by inlaying. The pressure in the sewage pipe can be adjusted by changing the relative position of the pressure relief groove and the pressure relief key.

[0034] Embodiment 1

[0035] Reference Figure 1 , Figure 2 As shown, in an embodiment of the utility model, this embodiment provides a sewage pipe pressure stabilizing cover 100, including:

[0036] The pressure relief component 110 is fixed on the fixing component 130, and the inner wall thereof is provided with a pressure relief groove 113;

[0037] The fixing component 130 has one end connected to the sewage pipe and the other end connected to the pressure relief component 110, and has a pressure relief key 131 arranged corresponding to the pressure relief groove 113;

[0038] The pressure component 120 passes through the pressure relief component 110 and the fixing component 130, one end of which is fixed to the upper end of the pressure relief component 110, and the other end of which is fixed to the bottom of the fixing component 130;

[0039] Among them, when the pressure in the pipeline is too high, the pressure relief component 110 moves upward along the pressure relief key 131, and the relative pressure relief area of ​​the pressure relief groove 113 increases. When the pressure in the pipeline decreases, the pressure relief component 110 moves downward along the pressure relief key 131, so that the relative pressure relief area of ​​the pressure relief groove 113 decreases.

[0040] In one embodiment, the pressure relief component 110 is used to discharge the pressure in the sewage pipe. When the sewage pressure in the sewage pipe exceeds the safety range, the pressure in the sewage pipe will be discharged to the outside through the pressure relief component 110. The pressure relief component 110 is fixed on the fixing component 130, and a pressure relief groove 113 is provided on the inner wall of the pressure relief component 110.

[0041] See also Figure 5 In another embodiment, the fixing component 130 is used to fix the pressure relief component 110 to the sewage pipe. One end of the fixing component 130 is connected to the sewage pipe, and the other end is connected to the pressure relief component 110. A pressure relief key 131 corresponding to the pressure relief groove 113 is provided inside. Specifically, the shape of the pressure relief groove 113 can be square, triangular or other shapes, and the corresponding shape of the pressure relief key 131 can be square, triangular or other shapes. The specific shape can be selected according to the shape of the pressure relief groove 113.

[0042] In another embodiment, the pressure component 120 is used to fix the fixing component 130 and the pressure relief component 110, and squeeze the pressure relief component 110, so as to generate a certain pressure on the pressure relief component 110, so as to generate a certain pulling force between the pressure relief component 110 and the fixing component 130. The pressure component 120 runs through the pressure relief component 110 and the fixing component 130, with one end fixed to the upper end of the pressure relief component 110 and the other end fixed to the bottom of the fixing component 130. Specifically, the pressure component 120 and the pressure relief component 110 can be connected in an inlay manner, and the pressure component 120 is inlaid in the through hole 112 in the middle of the pressure relief component 110. The pressure component 120 and the fixing component 130 can be connected in an inlay manner, and the pressure component 120 is inlaid in the through hole 112 in the middle of the fixing component 130.

[0043] The pressure component 120 may be a spring 122 or other elastic element, and the specific one may be selected according to actual needs.

[0044] When the pressure in the pipeline is too high, the sewage in the pipeline squeezes the pressure relief component 110, and the pressure on the pressure relief component 110 is greater than the pressure on the pressure relief component 110 by the pressure component 120. The pressure relief component 110 will move upward along the pressure relief key 131, so that a certain gap is generated between the pressure relief groove 113 and the pressure relief key 131. As the pressure relief groove 113 continues to rise, the relative pressure relief area of ​​the gap between the pressure relief groove 113 and the pressure relief key 131 increases, and the sewage is discharged to the outside of the pressure relief component along the pressure relief groove 113, thereby achieving a pressure relief effect; when the sewage pressure in the pipeline decreases, the pressure relief component 110 moves downward under the action of the pressure piece, and the pressure relief groove 113 moves downward along the pressure relief key 131, so that the relative pressure relief area of ​​the gap between the pressure relief groove 113 and the pressure relief key 131 is reduced, so that the pressure in the sewage pipe is stabilized within a certain range, thereby achieving a pressure stabilization effect.

[0045] By providing the pressure component 120, a certain pressure can be generated between the pressure relief component 110 and the fixed component 130, so that the sewage in the sewage pipe has a certain pressure and can penetrate out of the pipe. At the same time, a pressure relief groove 113 is provided on the inner wall of the pressure relief component 110, and a pressure relief key 131 is provided on the corresponding fixed component 130. The pressure relief groove 113 and the pressure relief key 131 are fixedly connected by inlaying. The relative position of the pressure relief groove 113 and the pressure relief key 131 is changed to realize the adjustment of the pressure in the sewage pipe. The structure is simple, the pressure relief is rapid, the pressure relief effect is obvious, and it is easy to manufacture and maintain.

[0046] Embodiment 2

[0047] See also Figure 2 and Figure 4 In the embodiment of the utility model, the pressure component 120 includes:

[0048] A spring 122, one end of which is against the pressure relief component 110, and the other end of which is against one end of the connecting rod 121;

[0049] The sealing gasket 123 is provided with a locking nut 124 and is fixedly connected to the connecting rod 121 through the nut;

[0050] The connecting rod 121 passes through the pressure component 120 and the pressure relief component 110 , one end of which is pressed against one side of the pressure relief component 110 , and the other end of which is fixed to a side of the fixing component 130 away from the pressure relief component 110 through a locking nut 124 .

[0051] In this embodiment, the pressure component 120 includes a spring 122, a sealing gasket 123 and a connecting rod 121, wherein a certain pressure is generated between the pressure relief component 110 and the fixing component 130 by squeezing the spring 122. It should be explained that the pressure between the pressure relief component 110 and the fixing component 130 is a preset pressure value.

[0052] Specifically, one end of the spring 122 is against the pressure relief component 110, and the other end is against one end of the connecting rod 121. When the pressure in the sewage pipe is greater than the preset pressure value, the pressure relief component 110 moves upward, and the sewage is discharged through the pressure relief groove 113, thereby achieving the effect of reducing the pressure in the sewage pipe; when the pressure in the sewage pipe decreases, the pressure relief component 110 moves downward, so that the air pressure in the pipe is restored to the preset pressure value. The spring 122 can be used to adjust the pressure in the sewage pipe.

[0053] In another embodiment, the sealing gasket 123 is arranged at one end of the fixing component 130 away from the pressure relief component 110, the sealing gasket 123 is embedded in one end of the connecting rod 121, and is fixedly connected to the connecting rod 121 through an internal locking nut 124. Specifically, the sealing gasket 123 is used to loosen the locking nut 124, and the locking nut 124 is fixed inside the sealing gasket 123 by embedding. The locking nut 124 is used to fix the connecting rod 121 to the fixing component 130.

[0054] In another embodiment, the connecting rod 121 is used to connect the fixing component 130 and the pressure relief component 110, and enable the fixing component 130 and the pressure relief component 110 to move up and down along the connecting rod. One end of the connecting rod 121 is pressed on one side of the pressure relief component 110, and the other end is fixed to the side of the fixing component 130 away from the pressure relief component 110 through a locking nut 124. It should be noted that the connecting rod 121 passes through the spring 122 and presses the spring 122, so that a certain pressure is generated between the pressure relief component 110 and the fixing component 130.

[0055] Based on the above structure, the connecting rod 121 passes through the spring 122 and then passes through the pressure relief component 110 and the fixing component 130 in sequence, the sealing gasket 123 is embedded on the connecting rod 121, and the locking nut 124 is fixed to one end of the connecting rod 121. The spring 122 is squeezed by the locking nut 124, one end of the spring 122 squeezes the pressure relief component 110 and the other end squeezes the fixing component 130. A certain pressure is generated between the pressure relief component 110 and the fixing component 130 through the spring 122, that is, the preset pressure value in the sewage pipe.

[0056] By providing a spring 122, a certain pressure is generated between the pressure relief component 110 and the fixed component 130, so that the sewage pipe is at a preset pressure value, which is convenient for the discharge of sewage. At the same time, when the pressure in the sewage pipe is less than the preset pressure value, the pressure relief component 110 moves downward under the action of the spring 122, so that the pipe maintains a certain pressure value. The structure is simple. When the pressure value in the sewage pipe is large, the sewage can be quickly discharged through the pressure relief groove 113, thereby achieving pressure relief in the sewage pipe. By providing a spring 122 as a preset pressure value, it is easy to install and replace, and the relationship between the spring 122 and the pressure of the sewage pipe is used to adjust the pressure in the sewage pipe, and finally achieve the effect of stabilizing the pressure.
