Description

Technical Field

[0001] The utility model specifically relates to a sealing pipe structure of an air valve. Background Art

[0002] A damper is a device used to regulate and control air flow. It is widely used in ventilation, air conditioning, industrial ventilation and other systems. According to their functions, dampers are divided into regulating valves, check valves, fire dampers, etc., and according to their structures, they are divided into butterfly valves, shutter valves, plug-in valves, etc. Usually, dampers are composed of a valve body, a valve plate or blades, and an actuator. The performance indicators of dampers include the accuracy of air volume regulation, sealing and pressure resistance, among which sealing affects the operating efficiency and safety of the system.

[0003] Traditional dampers usually use rubber or other flexible materials as sealing gaskets. Although such materials can provide good sealing effects in the early stage, they may age, harden or wear over time and with changes in environmental conditions, thereby reducing the sealing effect. In addition, the central part of the butterfly valve is not easy to seal when opening and closing, which can easily cause air leakage, increase energy consumption, and even lead to reduced system performance and increased maintenance costs.

[0004] Therefore, it is necessary to invent a wind valve sealing pipe structure to solve the above problems. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The utility model provides Figure 1-5 The air valve sealing tube structure shown includes a sealing tube 1, with mounting components 2 provided at both ends of the sealing tube 1. The mounting components 2 at both ends are mounted on the inner side of the air valve housing 3 and correspond to the middle part of the valve plate 4.

[0031] Specifically, the air valve housing 3 includes two sets of shells 31, which are fixedly assembled. Positioning grooves 32 for positioning the mounting assembly 2 are provided on both sides of the assembly position of the two sets of shells 31;

[0032] Reference Figure 4-5 The mounting assembly 2 includes a mounting base plate 21, which is correspondingly mounted in the positioning groove 32. A positioning piece 22 extends from the mounting base plate 21, and a fixing sleeve 23 is further provided on the inner side of the positioning piece 22;

[0033] Specifically, both ends of the sealing tube 1 are sleeved on the outside of the fixed sleeve 23 , and the outer side is restricted by the positioning piece 22 . One end of the sealing tube 1 is sealed, and the other end extends to contact the valve piece 4 .

[0034] Specifically, a plurality of fixing holes 24 are provided on the mounting base plate 21 . Fixing bolts are provided in the fixing holes 24 to fix the mounting base plate 21 in the corresponding positioning grooves 32 .

[0035] In this embodiment, the mounting base plate 21 is mounted in the positioning slot 32 of the damper housing 3 using fixing bolts through the fixing holes 24. The inclination of the mounting base plate 21 is consistent with the inner inclination of the housing 31 to ensure alignment and stability of the overall installation.

[0036] Specifically, the mounting base 21 is at a certain angle to the fixed sleeve 23 and the positioning piece 22, and the mounting base 21 and the inner side of the shell 31 have the same inclination. The fixed sleeve 23 and the positioning piece 22 are arranged parallel to each other, and the sealing tube 1 is mounted on the upper and lower sets of fixed sleeves 23.

[0037] Specifically, the positioning piece 22 is arc-shaped as a whole and is wrapped around the outside of the sealing tube 1, keeping consistent with the curvature of the outer wall of the sealing tube 1. The fixing sleeve 23 is inserted into the sealing tube 1 and fits the inner wall of the sealing tube 1.

[0038] In this embodiment, both ends of the sealing tube 1 are sleeved onto the outside of the fixed sleeve 23, ensuring that the outer side of the sealing tube 1 is restricted by the positioning piece 22. The arc design of the positioning piece 22 makes it consistent with the curvature of the outer wall of the sealing tube 1, thereby providing better support and positioning.

[0039] Specifically, the sealing tube 1 is U-shaped as a whole, and a baffle 11 is provided inside to enclose a sealed space, and both sides of the baffle 11 extend to the valve plate 4.

The fixing sleeve 23 and positioning piece 22 are arranged parallel to each other, closely fitting the inner and outer walls of sealing tube 1 to enhance sealing efficiency.

[0043] In this embodiment, the U-shaped design of the sealing tube 1, together with the internal baffle 11, encloses a sealed space, which greatly improves the sealing performance when the valve is closed, effectively prevents gas leakage, and improves the overall performance of the system. By installing the base plate 21 and the fixing method of the positioning groove 32, as well as the use of the positioning block 25, the stability of the sealing tube structure in the air valve is guaranteed, reducing wear and displacement caused by vibration or long-term use. The structural design takes into account the needs of easy installation and maintenance. Through standardized components and simple fixing methods, it makes on-site installation and daily maintenance faster and more efficient. The design of the sealing tube allows for a certain degree of adjustment to meet the needs of air valves of different sizes and types, enhancing the versatility and market adaptability of the product.
