[0027] Specific implementation examples are given below.

[0028] like Figures 1 to 8 As shown in the embodiment of this utility model, a sealing air valve for fiberglass pipes includes a sealing air valve body 1; a ring 2 is fixedly installed on the top of the sealing air valve body 1, a support component 3 is provided on the inner wall of the ring 2, a first filter component 4 is provided on the inner wall of the ring 2, a second filter component 5 is provided on the inner wall of the ring 2, a snap-fit ​​component 6 is provided on the inner wall of the ring 2, and a blocking component 7 is provided on the inner wall of the ring 2; the support component 3 includes a limiting ring 31 and a fixing slide plate 32, the limiting ring 31 is fixedly installed on the bottom of the inner wall of the ring 2, and the fixing slide plate 32... Two sets of fixed sliding plates 32 are provided, and the two sets of fixed sliding plates 32 are fixedly installed on both sides of the top of the limiting ring 31. The fixed sliding plates 32 are fixedly installed with the ring 2. The first filter assembly 4 includes a first filter screen 41 and rectangular slots 42. The rectangular slots 42 are provided in several sets and are arranged in a ring on the surface of the first filter screen 41. The first filter screen 41 is slidably installed with the fixed sliding plate 32 through the rectangular slots 42. The first filter screen 41 is slidably installed with the ring 2. The second filter assembly 5 includes a second filter screen 51 and rectangular slots 52. The second filter screen... The second filter screen 51 has rectangular slots 42 on both sides of its surface. The second filter screen 51 is slidably installed with the fixed slide plate 32 through the rectangular slots 42. The second filter screen 51 is also slidably installed with the ring 2. Small rectangular slots 52 are formed on the sides of the second filter screen 51 away from the rectangular slots 42. The snap-fit ​​assembly 6 includes a fixed long plate 61 and a groove 62. Two sets of fixed long plates 61 are provided, and the two sets of fixed long plates 61 are fixedly installed on the inner wall of the ring 2 on the side away from the fixed slide plate 32. The first filter screen 41 is connected to the fixed long plate 61 through the rectangular slots 42. The sliding installation has grooves 62 on both sides of the top of the fixed long plate 61. The second filter screen 51 is movably engaged with the fixed long plate 61 through the rectangular slot 52. The blocking component 7 includes a barrier plate 71 and a spring 72. Two sets of barrier plates 71 are provided. The two sets of barrier plates 71 are rotatably installed on the top of the two sets of fixed sliding plates 32 on the side close to each other. The spring 72 is fixedly installed on the inner wall of the fixed sliding plate 32. The end of the spring 72 away from the fixed sliding plate 32 is fixedly installed with the barrier plate 71. The inner walls of the sealing air valve body 1 and the ring 2 are coated with anti-corrosion paint.

[0029] As Figures 1 to 8 shown, the cooperation of the limiting ring 31 and the fixed slide plate 32 can limit the first filter screen 41, so that it always remains within the safe range during use. Meanwhile, the fixed slide plate 32 can prevent the first filter screen 41 from shaking when it is installed with the second filter screen 51. The first filter screen 41 can filter the air so that impurities in the air cannot enter the inside of the sealing air valve body 1 to corrode or scratch the inner wall. The rectangular notch 42 can enable the first filter screen 41 to be quickly installed on the inner wall of the circular ring 2. The second filter screen 51 can preliminarily filter the air so that larger impurities can be filtered out. Meanwhile, the cooperation with the first filter screen 41 can achieve efficient filtering. The rectangular small notch 52 can enable the second filter screen 51 to be clamped and limited by the fixed long plate 61, so that the first filter screen 41 and the second filter screen 51 always maintain a certain distance. The cooperation of the fixed long plate 61 and the groove 62 can limit the second filter screen 51 through the rectangular small notch 52, so that it no longer slides downward, thereby ensuring that the first filter screen 41 and the second filter screen 51 maintain a certain distance and improve the filtering efficiency. The cooperation of the blocking plate 71 and the spring 72 can limit the first filter screen 41 and the second filter screen 51, so that they do not fall off or slide out during use, and can always remain on the inner wall of the circular ring 2 for filtering. The application of the anticorrosive paint can greatly increase the service life of the sealing air valve body 1. In addition, the first filter screen 41 and the second filter screen 51 can filter out some impurities, which can further improve the service life of the sealing air valve body 1.

[0030] Working principle: When working, first, the rectangular notch 42 opened on the surface of the first filter screen 41 is aligned with the fixed long plate 61 and the fixed slide plate 32. Then, the first filter screen 41 is slid and installed on the top of the limiting ring 31 from top to bottom. When the first filter screen 41 is installed, it will extrude the blocking plate 71 to make it level with the fixed slide plate 32. Until the first filter screen 41 moves away from the spring 72, the blocking plate 71 will be pushed to reset. After the first filter screen 41 is installed, the user picks up the second filter screen 51 and aligns the rectangular notch 42 opened on the surface of the rectangular small notch 52 with the fixed slide plate 32, while aligning the rectangular small notch 52 opened on the surface of the second filter screen 51 with the fixed long plate 61. Then, it starts to slide downward. When the second filter screen 51 slides to the fixed long plate 61, the rectangular small notch 52 will be clamped with the groove 62 opened on both sides of the fixed long plate 61, so that the second filter screen 51 no longer has the function of sliding downward. Thus, the first filter screen 41 and the second filter screen 51 can always maintain a certain distance, thereby improving the filtering effect. Then, the sealing air valve body 1 is installed at the use position for use. When the second filter screen 51 and the first filter screen 41 need to be disassembled, the user only needs to press the blocking plate 71 and then slide the second filter screen 51 and the first filter screen 41 upward and take them off, so as to realize quick disassembly, replacement and cleaning.
