Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valve technology, specifically a self-operated pressure regulating valve. Background Technology

[0002] A self-operated pressure regulating valve is an automatic regulating device that requires no external energy and is entirely driven by fluid pressure. It is widely used in industries such as petroleum, chemical, power, water supply, and HVAC for automatic pressure control in pipeline systems. Its working principle involves adjusting the valve core position based on changes in the fluid's own pressure, thereby controlling flow and pressure, maintaining system stability, and preventing equipment damage or production instability due to excessively high or low pressure.

[0003] Traditional pressure regulation methods generally rely on external energy sources, such as pneumatic, electric, or hydraulic drives. While these methods can effectively control system pressure in many situations, they also have some drawbacks:

[0004] Traditional pressure regulating valves require an additional air, power, or hydraulic source to drive the regulating device, which not only increases the complexity of the system but may also lead to increased energy consumption and maintenance costs.

[0005] Traditional pressure regulating valves may fail to maintain stable regulation under conditions of large pressure fluctuations. Especially when precise pressure control is required, the valve's response time may be long, causing the system pressure to exceed the set range and affecting the stability of the entire production process.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a self-operated pressure regulating valve. Utility Model Content

[0007] The purpose of this invention is to provide a self-operated pressure regulating valve to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The self-operated pressure regulating valve technical solution includes a valve body assembly, a pressure sensing assembly, and a valve core adjustment assembly;

[0010] The valve body assembly includes a valve seat, on which a fluid passage is provided;

[0011] The pressure sensing component includes a pressure sensor and a controller;

[0012] The valve core adjustment assembly includes a central shaft, a shaft base plate, a valve plate, a vertical plate, a spring, and a valve plate compression spring.

[0013] Valve plates are rotatably connected to both sides of the central shaft, the springs are installed on both sides of the vertical plate, and the vertical plate is installed on the shaft base plate, which is connected to the central shaft.

[0014] The pressure sensor is connected to the controller and is used to detect the system pressure and provide a signal to the controller.

[0015] As a preferred technical solution, the valve plate opens and closes by pressing the spring, the valve seat, and the valve plate extrusion mechanism.

[0016] As a preferred technical solution, the spring is a helical spring or a disc spring.

[0017] As a preferred technical solution, the sealing surface of the valve plate is made of rubber or polytetrafluoroethylene.

[0018] Compared with existing technologies, the advantages of this invention are: by setting a pressure sensor to monitor the system pressure in real time, and by using a spring and valve plate to compress the spring sheet to control the valve plate, it can quickly and accurately respond to pressure changes based on the flow and pressure in the channel, automatically adjusting the valve plate opening to maintain the system pressure within the set range. This effectively solves the problem of lag or instability in traditional self-operated valves when pressure fluctuations are large, significantly improving the accuracy and stability of pressure control.

[0024] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0025] like Figure 1 , Figure 2 and Figure 3 and Figure 4 As shown, this utility model provides a technical solution for a self-operated pressure regulating valve:

[0026] It includes the valve body assembly, the pressure sensing assembly, and the valve core adjustment assembly.

[0027] The valve body assembly is mainly composed of a valve seat 1, which has a fluid passage 11 for fluid to pass through, thereby realizing the pressure regulation function of the pipeline system.

[0028] The pressure sensing assembly includes a pressure sensor 21 and a controller 2. The pressure sensor 21 is installed at a suitable location on the valve body assembly to detect pressure changes within the system in real time. The pressure sensor 21 is connected to the controller 2 via a wire, transmitting the detected pressure signal to the controller 2. After receiving the signal from the pressure sensor 21, the controller 2 processes and analyzes the signal according to a preset program and algorithm.

[0029] The valve core adjustment assembly includes a central shaft 31, a shaft base plate 311, a valve plate 32, a vertical plate 33, a spring 34, and a valve plate compression spring 35. The central shaft 31 is vertically mounted on the valve seat 1, and the shaft base plate 311 is fixedly connected to the central shaft 31, serving to support and fix other components. The vertical plate 33 is mounted on the shaft base plate 311, and springs 34 are mounted on both sides of the vertical plate 33. Springs 34 can be helical springs or disc springs, selected according to actual design requirements. Valve plates 32 are rotatably connected to both sides of the central shaft 31. The sealing surface of the valve plates 32 is made of rubber or polytetrafluoroethylene, providing good sealing performance. The valve plate compression spring 35 is positioned between the valve plate 32 and the valve seat 1, forming a valve plate opening and closing structure with the valve seat 1 through the valve plate compression spring 35, the spring 34, and the valve plate. When the system pressure changes, the controller 2, based on the signal from the pressure sensor 21, controls the interaction of the components in the valve core adjustment assembly to adjust the opening and closing of the valve plate 32.

[0030] Pressure sensor 21 is electrically connected to controller 2 via wires to ensure accurate and stable transmission of pressure signals. The central shaft 31 is rotatably connected to valve seat 1 via bearings or other suitable rotating connection structures to ensure flexible rotation of the central shaft 31. Valve plate 32 is rotatably connected to central shaft 31 via pins or other rotating connectors, allowing valve plate 32 to rotate around central shaft 31. The two ends of spring 34 are respectively connected to the vertical plate 33 and valve plate compression spring 35 or corresponding parts of valve plate 32. The specific connection method can be designed according to the type of spring 34 and installation requirements to achieve the elastic effect of spring 34 on valve plate 32. One end of valve plate compression spring 35 is connected to valve plate 32, and the other end contacts valve seat 1, assisting the opening and closing action of valve plate 32 through elastic deformation.

[0031] Install the self-regulating pressure regulating valve in the pipeline system that requires pressure regulation, ensuring that the fluid passage 11 is connected to the pipeline system and that all components are securely installed and correctly connected.

[0032] The required pressure range value of the system is preset in controller 2.

[0033] When the fluid pressure in the pipeline system changes, the pressure sensor 21 detects the pressure change in real time and transmits the pressure signal to the controller 2.

[0034] After receiving the pressure signal, the controller 2 compares and analyzes it with the preset pressure range value. Through the action of the valve core adjustment component, the valve plate 32 is rotated in the closed direction, reducing the opening of the fluid passage 11, thereby reducing the system pressure; if the system pressure is lower than the preset lower limit value, the controller 2 sends the opposite control signal, causing the valve plate 32 to rotate in the open direction, increasing the opening of the fluid passage 11, and increasing the system pressure.

[0035] By continuously monitoring the system pressure and adjusting the opening of the valve plate 32 in real time, the self-regulating pressure regulating valve maintains the system pressure within the set pressure range, ensuring the stable operation of the pipeline system.

[0036] The working principle and usage process of this utility model: After assembling the various components of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
