Description
Technical Field
[0001] This utility model relates to the field of high pressure pressure reducing valve adjustment technology, and in particular to a high pressure pressure reducing valve adjustment device. Background Technology
[0002] With the continuous advancement of industrialization, high-pressure fluid control technology has been widely applied in various fields, especially in places where precise control of pressure and flow is required, such as chemical, metallurgical, and power industries. High-pressure pressure reducing valves have become crucial equipment. The main function of high-pressure pressure reducing valves is to regulate fluid pressure to ensure the stability of fluid pressure in the system, so as to avoid equipment damage or safety hazards caused by excessive pressure. In order to improve the pressure reduction effect, modern pressure reducing valves are usually designed with multiple adjustment mechanisms, such as valve body, gate, and spring device. However, due to factors such as water flow impact and frequent operation, the internal components of the valve body are prone to wear, affecting the service life and stability of the equipment.
[0003] Existing high-pressure pressure reducing valves generally consist of an inlet pipe, valve body, outlet pipe, gate, and spring device. Their working principle is usually that water flows into the valve body through the inlet pipe, and after being regulated by the gate, it flows out to the outlet pipe.
[0004] In existing high-pressure pressure reducing valve designs, the direct impact of water flow on the gate plate within the valve body often leads to valve plate displacement or tilting. The impact force of the water flow causes instability in the valve plate's position, resulting in the valve body's inability to accurately regulate flow and pressure. Furthermore, the valve plate is prone to wear or misalignment under long-term impact from high-pressure water flow, which not only affects the normal operation of the pressure reducing valve but also reduces its service life. In addition, the tilting or displacement of the valve plate during long-term use often leads to valve failure or requires frequent maintenance, increasing equipment maintenance costs. Therefore, a high-pressure pressure reducing valve regulating device is proposed to solve these problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a high-pressure pressure reducing valve regulating device, which aims to improve the problem in the prior art that the valve plate is prone to wear or misalignment under the long-term impact of high-pressure water flow.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure pressure reducing valve regulating device, comprising a valve body, an inlet pipe fixedly connected to one side of the valve body, an outlet pipe fixedly connected to the other side of the valve body, a connecting rod rotatably connected inside the valve body, a gate plate fixedly connected to the outer wall of the connecting rod, a fixing plate fixedly connected inside the valve body, and a buffer assembly provided inside the fixing plate;
[0007] The buffer assembly includes a hollow frame and a sliding frame. The outer wall of the hollow frame is fixedly connected to the outer wall of the fixed plate. The sliding frame is slidably connected inside the hollow frame. A baffle is fixedly connected to one end of the sliding frame. A spring is provided inside the hollow frame. One end of the spring is fixedly connected to the inside of the hollow frame, and the other end of the spring is fixedly connected to the bottom of the sliding frame. A fixed frame is fixedly connected to the top of the valve body. A limit component is provided on the top of the fixed frame.
[0008] As a further description of the above technical solution:
[0009] The limiting component includes a hollow cylinder, the bottom of which is fixedly connected to the top of the fixed frame, and a circular hole is provided inside the hollow cylinder.
[0010] As a further description of the above technical solution:
[0011] The connecting rod is rotatably connected inside the hollow cylinder, and a handle is fixedly connected to the outer wall of the connecting rod.
[0012] As a further description of the above technical solution:
[0013] A support frame is fixedly connected to the top of the handle, and a pin is slidably connected inside the support frame.
[0014] As a further description of the above technical solution:
[0015] A pull ring is fixedly connected to the top of the pin, and the bottom of the pin engages with the round hole.
[0016] As a further description of the above technical solution:
[0017] A disc is fixedly connected to the outer wall of the pin, and the bottom of the disc fits against the top of the handle.
[0018] As a further description of the above technical solution:
[0019] A second spring is fitted on the outer wall of the pin. One end of the second spring is fixedly connected to the top of the disc, and the other end of the second spring is fixedly connected to the inside of the support frame.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, water flows from the inlet pipe into the valve body and then out through the outlet pipe. When the water flows through the inlet pipe, it impacts the baffle inside the inlet pipe, causing the sliding frame to slide inside the hollow frame and compress the spring. This achieves the effect of buffering and reducing the pressure of the water flowing through the valve body, solving the problem of the valve plate being displaced or tilted due to the long-term direct impact of the water flow on the gate plate inside the valve body, and improving the service life of the pressure reducing valve.
[0022] 2. In this utility model, by pulling the pull ring, the pin slides up and down, and at the same time, the disc compresses the spring, causing the pin to separate from the hole. Then, by rotating the handle, the connecting rod is driven to deflect the gate plate inside the valve body, thereby achieving the effect of limiting the rotation angle of the gate plate. This solves the problem that the valve plate cannot be limited when it rotates to a certain angle, and improves the practicality of the pressure reducing valve. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a high-pressure pressure reducing valve regulating device, including a valve body 1, an inlet pipe 2 fixedly connected to one side of the valve body 1, an outlet pipe 3 fixedly connected to the other side of the valve body 1, a connecting rod 6 rotatably connected inside the valve body 1, a gate plate 19 fixedly connected to the outer wall of the connecting rod 6, a fixing plate 8 fixedly connected inside the valve body 1, and a buffer assembly provided inside the fixing plate 8.
[0031] The buffer assembly includes a hollow frame 9 and a sliding frame 10. The outer wall of the hollow frame 9 is fixedly connected to the outer wall of the fixed plate 8. The sliding frame 10 is slidably connected inside the hollow frame 9. A baffle 11 is fixedly connected to one end of the sliding frame 10. A spring 12 is installed inside the hollow frame 9. One end of the spring 12 is fixedly connected inside the hollow frame 9, and the other end is fixedly connected to the bottom of the sliding frame 10. Through the cooperation of the sliding frame 10 and the spring 12, when water flows into the valve body 1, the water flow will generate an impact force on the baffle 11, thereby pushing the sliding frame 10 to slide inside the hollow frame 9, thus compressing the spring 12. The elastic force of the spring 12 plays a role in... The buffering effect reduces the impact force of the water flow, effectively preventing the water flow from directly impacting the gate 19, avoiding displacement or tilting of the valve plate, thereby improving the service life and stability of the pressure reducing valve. A fixed frame 4 is fixedly connected to the top of the valve body 1, and a limit component is provided on the top of the fixed frame 4. The function of the limit component is to limit the movement angle of the gate 19 inside the valve body 1, ensuring that it can move at a predetermined angle during operation, thereby avoiding the unstable position of the gate 19 when it rotates excessively. Through this limit function, the gate 19 inside the valve body 1 can work more stably, further improving the performance of the pressure reducing valve.
[0032] Reference Figure 1 - Figure 4The limiting assembly includes a hollow cylinder 5, the bottom of which is fixedly connected to the top of a fixed frame 4. A circular hole 13 is provided inside the hollow cylinder 5. A connecting rod 6 is rotatably connected inside the hollow cylinder 5. A handle 7 is fixedly connected to the outer wall of the connecting rod 6. A support frame 14 is fixedly connected to the top of the handle 7. A pin 15 is slidably connected inside the support frame 14. A pull ring 18 is fixedly connected to the top of the pin 15. The bottom of the pin 15 engages with the circular hole 13. A disc 16 is fixedly connected to the outer wall of the pin 15. The bottom of the disc 16 fits against the top of the handle 7. A second spring 17 is sleeved on the outer wall of the pin 15. One end of the second spring 17 is fixedly connected to the top of the disc 16, and the other end is fixedly connected to the inside of the support frame 14. In this limiting assembly, the hollow cylinder 5 serves as a fixed support, ensuring the stability of the entire assembly. The connecting rod 6 is rotatably connected to... The hollow cylinder 5 allows subsequent components to be flexibly adjusted or rotated. The handle 7 provides a convenient rotational torque through its fixed connection with the connecting rod 6. The support frame 14 provides support for the entire device and allows the pin 15 to slide within the frame. The pin 15 engages with the round hole 13, serving as a limit and positioning device to ensure that the relative positions of each component are fixed in the working state. The disc 16 on the outer wall of the pin 15 reinforces and stabilizes the pin 15, preventing it from sliding or falling off. The second spring 17 acts as an elastic element, ensuring that the pin 15 can self-reset in a specific position, avoiding excessive movement or vibration from affecting the component. The presence of the second spring 17 ensures that the pin 15 can provide reliable tension during operation, while also adapting to different operating requirements, improving the stability and ease of operation of the component.
[0033] Working Principle: When using a high-pressure pressure reducing valve, if it is necessary to buffer the water pressure, the water flows into the valve body 1 through the inlet pipe 2. As the water flows through the inlet pipe 2, it first impacts the baffle 11. When the baffle 11 is subjected to this impact, it causes the sliding frame 10 to slide into the hollow frame 9. When the sliding frame 10 slides inside the hollow frame 9, it compresses the spring 12. Through the compression and reset of the spring 12, the water flow into the valve body 1 is buffered, thereby achieving the effect of regulating and buffering the water pressure. Then, by pulling the pull ring 18... The movable pin 15 and the disc 16 compress the second spring 17, causing the pin 15 to separate from the round hole 13. Then, by rotating the handle 7, the connecting rod 6 is rotated. The rotation of the connecting rod 6 causes the gate 19 to rotate inside the valve body 1, controlling the opening and closing. When it is necessary to limit the opening and closing angle of the gate 19, the pull on the pull ring 18 is released when the connecting rod 6 is rotated. At this time, the compressed second spring 17 is reset, causing the disc 16 to move downward. As the disc 16 moves downward, it causes the pin 15 to move into the round hole 13, thereby achieving the purpose of limiting the opening and closing angle of the gate 19.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
