Description

Technical Field

[0001] This utility model relates to the technical field of three-way valve components, specifically a spring elastic reinforcement structure for a three-way valve used in strong vibration environments. Background Technology

[0002] In high-vibration environments such as mining and construction machinery, the three-way valve, as a key component for controlling fluid flow and pressure regulation, directly affects the safe and stable operation of the equipment due to the performance of its internal spring. Currently, three-way valves generally use ordinary helical springs as their elastic core component. While this meets basic elastic reset requirements, it presents the following prominent problems:

[0003] Insufficient strength and easy fatigue failure: Ordinary helical springs are mostly made of conventional spring steel. Under high frequency and high intensity vibration conditions, the spring steel wire is subjected to repeated alternating stress, which easily causes stress concentration at the contact points between coils, leading to premature plastic deformation, cracks or even breakage.

[0004] Lack of damping and buffering exacerbates vibration transmission: Existing three-way valves do not have a targeted damping mechanism. During vibration, the springs rely solely on their own elastic deformation to absorb energy, which cannot effectively attenuate external impacts.

[0005] This results in a short lifespan for the entire spring, thus requiring improvement. Utility Model Content

[0006] The purpose of this invention is to provide a spring-elastic reinforcement structure for a three-way valve in a high-vibration environment, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spring-elastic reinforcement structure for a three-way valve in a strong vibration environment, comprising an elastic body, wherein a damping mechanism is installed on the outer side of the elastic body;

[0008] The elastic body includes a base, a circular wave-shaped ring is placed inside the base, and a top ring is placed on top of the circular wave-shaped ring;

[0009] The damping mechanism includes a top block, which is fixedly connected to the top of the top ring. An inner damping rod is fixedly connected to the outer side of the top block, and an outer damping strip is inserted into the bottom of the inner damping rod. The inner side of the outer damping strip is fixedly connected to the outer wall of the base.

[0010] Preferably, the base has a through hole in the middle, and the base has a placement groove around the outer ring of the through hole, and the circular wave ring is placed in the placement groove.

[0011] Preferably, multiple circular wave rings are provided, and the multiple circular wave rings are stacked and cross-combined in the placement groove, and the multiple circular wave rings are welded together.

[0012] Preferably, a reinforcing ring is fixedly connected to the outer side of the inner damping rod near the top, and a damping groove is opened in the middle of the damping strip, with the inner damping rod inserted into the outer damping groove.

[0013] Preferably, the inner wall of the damping groove is densely and uniformly fixedly connected with first damping protrusions, and the outer side of the inner damping rod is densely and uniformly fixedly connected with second damping protrusions.

[0014] Preferably, the second damping protrusion on the outer side of the inner damping rod and the first damping protrusion on the inner side of the damping groove are distributed intersectingly.

[0015] Compared with the prior art, this utility model provides a spring-reinforced structure for a three-way valve in a high-vibration environment, which has the following beneficial effects:

[0016] 1. The three-way valve spring is reinforced with an elastic structure for high-vibration environments. Through a multi-circular wave-shaped ring superimposed and cross-welded elastic body design, the spring strength and fatigue resistance are significantly improved. The elastic body uses a structure of multiple superimposed and cross-welded circular wave-shaped rings. Compared to ordinary helical springs, its force-bearing area is increased, and the stress distribution is more uniform, effectively dispersing alternating stress under high-vibration environments. When the three-way valve is subjected to vibration and impact, the circular wave-shaped rings absorb energy through the elastic deformation of the wave-shaped structure. The superimposed rings support each other, preventing overload of a single ring. Simultaneously, the welding fixation enhances overall rigidity and prevents localized wear caused by relative sliding between rings.

[0017] 2. This high-vibration environment utilizes a three-way valve with a spring-reinforced structure. Through the interlocking of the inner damping rod and the outer damping strip's protrusions, a highly efficient damping and buffering system is constructed. In the damping mechanism, the inner damping rod is inserted into the damping groove of the outer damping strip, and the first and second damping protrusions of both are interlocked, forming multi-contact friction damping. The working principle is as follows: During strong vibrations, the elastic body extends and retracts, causing the top block to move up and down. The inner damping rod slides within the damping groove of the outer damping strip, and the interlocking protrusions collide and rub against each other, converting the vibration kinetic energy into heat energy. Simultaneously, the clearance between the inner wall of the damping groove and the inner damping rod restricts the lateral displacement of the spring. This design reduces vibration transmission efficiency, decreases wear on the valve core and seals, and, combined with the high strength of the elastic body, extends the overall service life of the three-way valve, improving equipment operational stability.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1-3 A spring-reinforced structure for a three-way valve in a high-vibration environment includes an elastic body 1 and a damping mechanism 2 installed on the outside of the elastic body 1.

[0030] The elastic body 1 includes a base 13, a circular wave ring 12 is placed inside the base 13, and a top ring 11 is placed on top of the circular wave ring 12;

[0031] The design of the elastic body 1, featuring multiple overlapping and cross-welded circular wave rings 12, significantly enhances the spring's strength and fatigue resistance. The elastic body 1 utilizes a structure where multiple overlapping and cross-welded circular wave rings 12 are combined and fixed. Compared to ordinary helical springs, this structure increases the force-bearing area and provides a more uniform stress distribution, effectively dispersing alternating stress under strong vibration environments. When the three-way valve is subjected to vibration and impact, the circular wave rings 12 absorb energy through the elastic deformation of their wave-shaped structure. The overlapping rings support each other, preventing overload of any single ring. Simultaneously, the welding and fixing enhances overall rigidity, preventing localized wear caused by relative sliding between rings.

[0032] The base 13 has a through hole 15 in the middle, and a placement groove 14 is formed on the outer ring of the through hole 15. The circular wave ring 12 is placed in the placement groove 14.

[0033] Multiple circular wave rings 12 are provided, and the multiple circular wave rings 12 are stacked and cross-combined in the placement groove 14, and the multiple circular wave rings 12 are welded together.

[0034] Example 2

[0035] Please see Figure 1-5 Furthermore, based on Embodiment 1, the damping mechanism 2 further includes a top block 21, which is fixedly connected to the top of the top ring 11. An inner damping rod 22 is fixedly connected to the outside of the top block 21, and an outer damping strip 23 is inserted into the bottom of the inner damping rod 22. The inner side of the outer damping strip 23 is fixedly connected to the outer wall of the base 13.

[0036] A high-efficiency damping buffer system is constructed by the cross-cooperation of the inner damping rod 22 and the outer damping strip 23. In the damping mechanism 2, the inner damping rod 22 is inserted into the damping groove 24 of the outer damping strip 23, and the first and second damping protrusions 26 of the two are cross-distributed to form multi-contact friction damping. The working principle is as follows: During strong vibration, the elastic body 1 extends and retracts, causing the top block 21 to move up and down. The inner damping rod 22 slides in the damping groove 24 of the outer damping strip 23. The cross-distributed protrusions collide and rub against each other, converting the vibration kinetic energy into heat energy for consumption. At the same time, the gap between the inner wall of the damping groove 24 and the inner damping rod 22 restricts the lateral displacement of the spring. This design can reduce the vibration transmission efficiency, reduce the wear of the valve core and seals, and, combined with the high strength characteristics of the elastic body 1, extend the overall service life of the three-way valve and improve the operational stability of the equipment.

[0037] A reinforcing ring 27 is fixedly connected to the outer side of the inner damping rod 22 near the top. A damping groove 24 is opened in the middle of the damping strip, and the inner damping rod 22 is inserted into the outer damping groove 24.

[0038] The inner wall of the damping groove 24 is densely and uniformly fixedly connected with first damping protrusions 25, and the outer side of the inner damping rod 22 is densely and uniformly fixedly connected with second damping protrusions 26.

[0039] The second damping protrusion 26 on the outer side of the inner damping rod 22 and the first damping protrusion 25 on the inner side of the damping groove 24 are interspersed.

[0040] In actual operation, when this device is used, the design of the elastic body 1, which consists of multiple overlapping and cross-welded circular wave rings 12, significantly improves the spring strength and fatigue resistance. The elastic body 1 adopts a structure in which multiple overlapping and cross-welded circular wave rings 12 are combined and fixed. Compared with ordinary helical springs, its force-bearing area is expanded and the stress distribution is more uniform, which can effectively disperse alternating stress under strong vibration environment. When the three-way valve is subjected to vibration and impact, the circular wave rings 12 absorb energy through the elastic deformation of the wave-shaped structure. The overlapping rings support each other, avoiding overload of a single ring. At the same time, the welding and fixing enhances the overall rigidity and prevents local wear caused by relative sliding between rings.

[0041] The inner damping rod 22 and the outer damping strip 23 interlock with each other to form a high-efficiency damping buffer system. In the damping mechanism 2, the inner damping rod 22 is inserted into the damping groove 24 of the outer damping strip 23, and the first and second damping protrusions 26 of the two are interlocked to form multi-contact friction damping. The working principle is as follows: During strong vibration, the elastic body 1 extends and retracts, causing the top block 21 to move up and down. The inner damping rod 22 slides in the damping groove 24 of the outer damping strip 23. The interlocked protrusions collide and rub against each other, converting the vibration kinetic energy into heat energy for consumption. At the same time, the gap between the inner wall of the damping groove 24 and the inner damping rod 22 restricts the lateral displacement of the spring. This design can reduce the vibration transmission efficiency, reduce the wear of the valve core and seals, and, combined with the high strength characteristics of the elastic body 1, extend the overall service life of the three-way valve and improve the operational stability of the equipment.
