Description

TECHNICAL FIELD

[0001] The utility model application relates to exhaust valve technical field, specifically a kind of wear-resistant compression exhaust valve sleeve assembly. BACKGROUND

[0002] Wear-resistant compression exhaust valve sleeve assembly is a kind of equipment for pipeline system, mainly used for exhaust, drainage or prevent gas accumulation in pipeline, its key feature is wear-resistant, compression, usually applied in high pressure, easy to wear or need high temperature, corrosion-resistant environment.

[0003] When the exhaust passage in the existing exhaust valve is connected with other pipelines, fasteners (such as hex bolts) are usually used for fastening. Although this connection method is widely used, there are indeed some potential drawbacks in the long-term use process, especially in high-pressure, high-temperature or vibration environment. In industrial environment, the pipeline system is usually subjected to mechanical vibration or water flow impact, which can cause the bolts to gradually loosen. When the exhaust valve is in a high-pressure environment, the tightening force of the bolts may change with the rise and fall of the pressure, causing the bolts to loosen. When the bolts loosen, the fastened connection surface will have a slight displacement or gap, which can cause poor sealing and leakage. SUMMARY

[0004] To solve the problem that the exhaust passage in the traditional exhaust valve is usually fastened with fasteners when connected with other pipelines, but it is easy to loosen during long-term use, the utility model provides a wear-resistant compression exhaust valve sleeve assembly to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] Further, the moving assembly comprises a second sliding groove opened on the outer wall of the exhaust passage, a second sliding block in sliding connection with the second sliding groove, and a second spring arranged in the second sliding groove.

[0008] Further, one end of the second spring is connected with the outer wall of the second sliding block, and the other end of the second spring is connected with the inner wall of the second sliding groove. This design can control the force and speed of movement through the compression and release of the spring when the second sliding block moves, while providing stable resistance to avoid damage caused by excessive operation.

[0009] Further, the second sliding groove is symmetrically arranged on the outer wall of the exhaust passage, which ensures the balance of the component and avoids deviation or damage caused by unilateral force.

[0010] Further, the reinforcing assembly comprises a mounting plate connected with the second sliding block, a first sliding groove arranged in the mounting plate, a first sliding block in sliding connection with the first sliding groove, a reinforcing rod connected with the first sliding block and inserted into the mounting plate, a first spring wound on the outer wall of the reinforcing rod, a pull rod fixed on the outer end of the reinforcing rod, and a limiting groove arranged in the hexagonal bolt, which can ensure uniform and effective reinforcement of each hexagonal bolt during the reinforcement process, thereby improving the overall connection strength and stability.

[0011] Further, one end of the first spring is connected with the outer wall of the first sliding block, and the other end of the first spring is connected with the inner wall of the mounting plate, which can also control the moving force and speed of the reinforcing rod and ensure that the hexagonal bolt and the exhaust passage are not damaged by excessive impact during operation.

[0012] Further, the caliber of the reinforcing rod is equal to the caliber of the limiting groove, which ensures that the reinforcing rod can be accurately inserted into the limiting groove to form a firm lock and prevent loosening under the action of vibration or pressure, and the outer wall of the pull rod is provided with anti-skid lines, which increases the friction force when the operator holds the pull rod, making the operation more convenient, especially when a larger force is required to pull, the anti-skid lines can effectively prevent the hand from slipping and improve the safety and efficiency of the operation.

[0014] 1. Enhanced fastening force: the design of the reinforcing assembly makes the connection of the hexagonal bolt and the exhaust passage more firm, and through the action of the first spring and the second spring, the reinforcing rod can be closely combined with the limiting groove of the hexagonal bolt to provide additional fastening force and prevent the bolt from loosening due to vibration or pressure change.

[0015] 2. Reliable sealing performance: since the reinforcing assembly can effectively prevent the bolt from loosening, it can ensure that the connection surface of the exhaust passage and other pipelines remains closely fitted, avoiding poor sealing and leakage problems caused by gaps or displacement.

[0016] 3. Adapt to high pressure environment: in a high pressure environment, the fastening force of the bolt may change with the rise and fall of the pressure, and the device can adapt to such changes through the pre-tightening force of the spring and the design of the reinforcing rod, maintaining stable fastening effect.

[0017] 4. Improve production safety: in the high pressure and high temperature industrial environment, leakage can cause serious safety accidents, the sealing performance and fastening force of the device help to prevent such accidents and improve production safety. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the application purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in the following description of the drawings. Obviously, the following described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] REFERENCE Figures 1-5The utility model provides a wear -resisting compression -resistant exhaust valve sleeve assembly, including exhaust valve body 1, the end of exhaust valve body 1 is provided with valve cover 2, is provided with exhaust passage 3 on exhaust valve body 1, is connected with hexagon bolt 4 on exhaust passage 3, is connected with moving assembly 6 on the outer wall of exhaust passage 3, is connected with reinforcing assembly 5 in moving assembly 6, and reinforcing assembly 5 reinforces hexagon bolt 4;

[0027] Moving assembly 6 includes second sliding slot 62 set up on the outer wall of exhaust passage 3, second sliding block 61 slidably connected with second sliding slot 62, second spring 63 provided in second sliding slot 62.

[0028] Specifically, when the staff needs to use reinforcing assembly 5 to reinforce hexagon bolt 4, first, second sliding block 61 is moved forward to drive reinforcing assembly 5 to move forward, and reinforcing assembly 5 is slid forward in second sliding slot 62 by second sliding block 61, and the second spring 63 is extruded to generate deformation during the sliding process, it is worth noting that one end of the second spring 63 is connected with the outer wall of the second sliding block 61, and the other end of the second spring 63 is connected with the inner wall of the second sliding slot 62, and such design can control the force and speed of movement by compression and release of the spring when the second sliding block 61 moves, while providing stable resistance to avoid damage caused by excessive operation, and the second sliding slot 62 is symmetrically provided with two groups on the outer wall of the exhaust passage 3, and the symmetrical design ensures the balance of the assembly and avoids deviation or damage caused by unilateral force, and the reinforcing assembly 5 is connected above each second sliding block 61, which can ensure that each hexagon bolt 4 is uniformly and effectively reinforced during the reinforcing process, improve the overall connection strength and stability;

[0029] Reinforcing assembly 5 includes mounting plate 51 connected with second sliding block 61, first sliding slot 52 set up in mounting plate 51, first sliding block 53 slidably connected with first sliding slot 52, reinforcing rod 54 connected with first sliding block 53 and inserted into mounting plate 51, first spring 55 wound on the outer wall of reinforcing rod 54, pull rod 56 fixed on the outer end of reinforcing rod 54, and limiting groove 57 set up in hexagon bolt 4;

[0030] Before the mounting plate 51 moves through the second sliding block 61, the staff needs to pull the pull rod 56 outward in advance, so that the pull rod 56 drives the reinforcing rod 54 to move outward, and the reinforcing rod 54 slides in the first sliding groove 52 through the first sliding block 53, and extrudes the first spring 55 to generate deformation during the sliding process. Then, after the mounting plate 51 moves through the second sliding block 61 and extrudes the second spring 63 to generate deformation, the bottom end of the reinforcing rod 54 is just moved to the position of the limiting groove 57 at this time. At this time, the pull rod 56 is loosened and pulled, and at this time, the restoring force generated by the elasticity of the first spring 55 pushes the reinforcing rod 54 to restore, so that the bottom end of the reinforcing rod 54 is inserted with the limiting groove 57 to form fixation. At this time, the second spring 63 is always in a state of being extruded, generating a pulling force to drive the two groups of reinforcing rods 54 to move backward, further reinforcing the connection of the hexagonal bolt 4 and the exhaust passage 3.

[0031] It is worth noting that one end of the first spring 55 is connected with the outer wall of the first sliding block 53, and the other end of the first spring 55 is connected with the inner wall of the mounting plate 51. This design can also control the moving force and speed of the reinforcing rod 54, and ensure that the hexagonal bolt 4 and the exhaust passage 3 will not be damaged by excessive impact during operation. The caliber of the reinforcing rod 54 is equal to the caliber of the limiting groove 57, which ensures that the reinforcing rod 54 can be accurately inserted into the limiting groove 57 to form firm locking and prevent loosening under the action of vibration or pressure. The outer wall of the pull rod 56 is provided with anti-skid lines, which increases the friction force when the operator holds the pull rod, making the operation more convenient, especially when a larger force is needed to pull. The anti-skid lines can effectively prevent the hand from slipping, improving the safety and efficiency of the operation.
