Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an electric temperature difference balancing valve. Background Technology

[0002] An electric temperature difference balancing valve is a special type of valve that plays a dynamic balancing role in a hydraulic system. It can automatically adjust the flow rate according to the temperature difference in the system to ensure uniform temperature in all parts of the system and achieve energy saving.

[0003] The sealing performance between the valve stem and seat of existing electric temperature differential balancing valves is crucial for the normal operation of the valve and the stability of the system. Poor sealing performance between the valve stem and seat may lead to loosening of the rotating cap, resulting in a decrease in sealing performance. The rotating cap is part of the valve body and is usually used to fix and support the valve stem, ensuring the correct alignment and sealing between the valve stem and the valve seat. When the rotating cap becomes loose, the valve stem may undergo slight displacement, causing the sealing surface of the valve seat and the sealing surface of the valve stem to not make tight contact, resulting in leakage. If the loosening of the rotating cap is not detected and dealt with in time, it may worsen over time, causing damage to the valve stem and valve seat. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an electric temperature difference balancing valve. By using a reinforcement mechanism to clamp the outer wall of the valve stem, it ensures tight contact between the valve stem and the valve seat, improves the sealing performance, and prevents the problem of the sealing surface not being able to make tight contact due to the loosening of the rotating cap.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electric temperature difference balancing valve, including a valve body, a valve seat installed on the valve body, a valve stem inserted into the valve seat, a flow channel opened in the valve body, a reinforcing mechanism installed on the outer wall of the valve seat, the reinforcing mechanism clamping the outer wall of the valve stem, and a limit mechanism provided on the reinforcing mechanism.

[0006] As a preferred technical solution of this utility model, the reinforcement mechanism includes a base sleeved on the outer wall of the valve seat, a slide rod opened in the base, a first slide groove opened in the slide rod, a first slider slidably connected in the first slide groove, a first return spring set in the first slide groove, a movable plate connected to the first slider and inserted into the slide rod, and a reinforcement plate installed on the movable plate.

[0007] As a preferred embodiment of this utility model, one end of the first reset spring is connected to the outer wall of the first slider, and the other end of the first reset spring is connected to the inner wall of the first slide groove.

[0008] As a preferred technical solution of this utility model, the shape of the clamping end face of the reinforcing plate is set to be an arc shape that matches the outer wall of the valve stem. Three sets of reinforcing plates are evenly arranged around the base. Limiting mechanisms are provided on the outer wall of the base and the movable plate.

[0009] As a preferred technical solution of this utility model, the limiting mechanism includes three sets of mounting cavities evenly installed around the base, a second sliding groove opened in the mounting cavity, a second slider slidably connected to the second sliding groove, a limiting rod connected to the second slider and inserted into the mounting cavity, a second return spring wound on the outer wall of the limiting rod, a first limiting groove and a second limiting groove opened in the movable plate, and a pull rod fixed on the outer end wall of the limiting rod.

[0010] As a preferred embodiment of this utility model, the first limiting groove and the second limiting groove have the same diameter, and the first limiting groove and the second limiting groove are arranged in parallel at both ends of the movable plate.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. Improved sealing performance: The clamping mechanism on the outer wall of the valve stem ensures tight contact between the valve stem and the valve seat, improving sealing performance and preventing the sealing surfaces from not being in close contact due to loosening of the rotating cap. The arc-shaped clamping end face of the reinforcing plate and the cooperation with the outer wall of the valve stem provide uniform clamping force, further ensuring the sealing effect between the valve stem and the valve seat.

[0013] 2. Preventing the rotating cap from loosening: The design of the reinforcement mechanism ensures that the valve stem is more firmly fixed in the valve seat, reducing the possibility of the rotating cap loosening due to vibration or long-term use. The use of the limit mechanism ensures the correct position of the movable plate and the reinforcement plate during operation, avoiding valve stem displacement caused by the loosening of the rotating cap.

[0014] 3. Improved valve stability and reliability: The first and second return springs ensure that the moving plate and limit rod return to their correct positions during operation, thus maintaining valve stability. The design of the limit mechanism, including the parallel and equal-diameter setting of the first and second limit grooves, ensures precise engagement of the limit mechanism after operation, further enhancing valve reliability.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example:

[0022] like Figure 1-4 As shown, an electric temperature difference balancing valve includes a valve body 1, a valve seat 2 installed on the valve body 1, a valve stem 3 inserted into the valve seat 2, a flow channel 4 opened in the valve body 1, a reinforcing mechanism 5 installed on the outer wall of the valve seat 2, the reinforcing mechanism 5 clamps the outer wall of the valve stem 3, and a limit mechanism 6 is provided on the reinforcing mechanism 5.

[0023] The reinforcing mechanism 5 includes a base 51 sleeved on the outer wall of the valve seat 2, a slide rod 52 opened in the base 51, a first slide groove 53 opened in the slide rod 52, a first slider 54 slidably connected in the first slide groove 53, a first return spring 55 provided in the first slide groove 53, a movable plate 56 connected to the first slider 54 and inserted into the slide rod 52, and a reinforcing plate 57 installed on the movable plate 56.

[0024] Before the operator connects the valve stem 3 to the valve seat 2, the reinforcing plate 57 is pulled outward, causing the reinforcing plate 57 to drive the movable plate 56 to slide outward within the slide bar 52. The first return spring 55 slides outward within the first slide groove 53 via the first slider 54. During the sliding process, the first return spring 55 is compressed and deformed until it is pulled to the outermost end. Then, the position of the movable plate 56 is restricted by the limiting mechanism 6. After all three sets of reinforcing plates 57 have moved outward to the outermost end and are all restricted by the limiting mechanism 6, the valve stem 3 is connected to the valve seat 2. At this time, the limiting mechanism 6 is released from restricting the movable plate 56. The restoring force generated by the elasticity of the first return spring 55 pushes the movable plate 56 to return to its original position, and finally drives the reinforcing plate 57 to clamp and fix the outer wall of the valve stem 3.

[0025] It is worth noting that one end of the first return spring 55 is connected to the outer wall of the first slider 54, and the other end of the first return spring 55 is connected to the inner wall of the first slide groove 53. This ensures that when the movable plate 56 and the reinforcing plate 57 are pulled outward, the first return spring 55 can extend with the movement of the first slider 54 and store elastic potential energy.

[0026] The shape of the clamping end face of the reinforcing plate 57 is set to be arc-shaped to match the outer wall of the valve stem 3. This can better adapt to the shape of the outer wall of the valve stem 3, provide uniform and firm clamping force, and prevent the valve stem 3 from rotating or loosening in the valve seat 2. Three sets of reinforcing plates 57 are evenly arranged around the base 51. The evenly distributed reinforcing plates 57 can ensure the uniform distribution of clamping force and prevent the valve stem 2 from being damaged or leaking due to uneven force. Limiting mechanisms 6 are provided on the outer wall of the base 51 and the movable plate 56.

[0027] The limiting mechanism 6 includes three sets of mounting cavities 61 evenly installed around the base 51, a second sliding groove 62 opened in the mounting cavity 61, a second slider 63 slidably connected to the second sliding groove 62, a limiting rod 64 connected to the second slider 63 and inserted into the mounting cavity 61, a second return spring 65 wound around the outer wall of the limiting rod 64, a first limiting groove 66 and a second limiting groove 67 opened in the movable plate 56, and a pull rod 68 fixed on the outer end wall of the limiting rod 64;

[0028] Before connecting the valve seat 2 and the valve stem 3, the operator pulls the lever 68 outward, causing the lever 68 to move the limiting lever 64 outward. The limiting lever 64 slides outward in the second slide groove 62 through the second slider 63. During the sliding process, the second return spring 65 is squeezed and deformed until the limiting lever 64 moves out of the second limiting groove 67 and releases the limitation on the movable plate 56. After the reinforcing plate 57 clamps the outer wall of the valve stem 3, the first limiting groove 66 moves to the position of the limiting lever 64. At this time, the pulled lever 68 is loosened, and the restoring force generated by the elasticity of the second return spring 65 pushes the limiting lever 64 to return to its original position, thereby engaging the second limiting groove 67 to form a limitation.

[0029] It is worth noting that the first limiting groove 66 and the second limiting groove 67 have the same diameter. The first limiting groove 66 and the second limiting groove 67 are arranged parallel to each other at both ends of the movable plate 56. The parallel and equal diameter design of these two limiting grooves allows the limiting rod 64 to move smoothly on the movable plate 56. At the same time, it ensures that when the limiting rod 64 returns to its original position, it can be precisely engaged, thereby keeping the position of the movable plate 56 unchanged and ensuring the accurate installation and firm fixation of the valve rod 3.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
