Embodiment 1
[0033] Such as figure 1 As shown, the tubular gas decompression device includes: a pipe body 1, two ends of the pipe body 1 are provided with connecting threads, and the space in the pipe body 1 is composed of a high-pressure chamber 101 and a low-pressure chamber 102; the inner diameter of the high-pressure chamber 101 is smaller than that of the low-pressure chamber The inner diameter of 102; fixed body 2, fixed body 2 is arranged in low-pressure chamber 102 and is connected with the inner surface of low-pressure chamber 102, and fixed body 2 is provided with the gap that passes through for gas; Spring 3, one end of spring 3 and fixed body 2 Connection; piston 4, piston 4 is connected with the other end of spring 3, spring 3 pushes piston 4 close to the end of high-pressure chamber 101; vent hole 5, vent hole 5 is evenly opened on the tube wall of low-pressure chamber 102, vent hole Both ends of 5 communicate with the inner space of the low-pressure chamber 102 , and the ven...
Embodiment 2
[0037] Such as figure 1 with image 3 As shown, this embodiment further describes the fixed body 2 on the basis of the embodiment 1. The fixed body 2 is a porous plate.
[0038] The holes on the fixed body 2 are used for gas to pass through.
Embodiment 3
[0040] Such as figure 1 with Figure 4 As shown, this embodiment further describes the fixed body 2 on the basis of the embodiment 1. The fixed body 2 includes a circular middle plate 201 and a connecting rod 202 evenly arranged on the outer surface of the circular middle plate 201. The connecting rod 202 is connected to the inner surface of the low-pressure chamber 102, and the spring 3 is connected to the circular middle Board 201 is connected.
[0041] The gaps between the connecting rods 202 are used for gas to pass through.
