[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figures 1-4 This invention describes a breathing valve according to an embodiment of the present invention, used for the discharge of gas, and has a wide range of applications.

[0018] like Figures 1-4 As shown, a breathing valve according to an embodiment of the present invention has a breathing valve body 100, a breathing valve cover 200, an air inlet 300, and multiple partitions 400.

[0019] Specifically, such as Figures 1-4 As shown, the breathing valve body 100 has an open structure at both ends.

[0020] Specifically, such as Figures 1-4 As shown, the breathing valve cover 200 is placed over one end opening of the breathing valve body 100.

[0021] Specifically, such as Figures 1-4 As shown, the air inlet 300 is located on the breathing valve cover 200. The air inlet 300 is a circular channel used for flow restriction.

[0022] Specifically, such as Figures 1-4 As shown, multiple baffles 400 are stacked and staggered on the inner wall of the breathing valve body 100. The baffles 400 have a fan-shaped structure, and the multiple baffles 400 divide the interior of the breathing valve body 100 into an S-shaped meandering channel, thereby achieving noise reduction when the restricted gas passes through. Figure 2 , 4 As shown, in this embodiment, there are three partitions 400.

[0023] Furthermore, such as Figures 1-4 As shown, a breathing valve according to an embodiment of the present invention further includes: a fixing plate 500, which is sleeved on the outside of the breathing valve body 100, and the fixing plate 500 is provided with a locking hole 501. The fixing plate 500 is used to fix the breathing valve to a designated device.

[0024] Furthermore, such as Figures 1-2 As shown, in one embodiment of this utility model, the breathing valve fixing plate 500 is located at the end of the breathing valve body 100 near the breathing valve cover 200, which is the first embodiment; as shown... Figures 3-4 As shown, the fixed plate 500 is located at the end of the breathing valve body 100 away from the breathing valve cover 200, which is the second embodiment.

[0025] Furthermore, such as Figures 1-4 As shown, the fixed plate 500 and the breathing valve body 100 are integrally formed, which improves strength and reliability.

[0026] Furthermore, such as Figures 1-4 As shown, the other end of the breathing valve body 100 is provided with a thread 600 for connecting to an external gas collection device to collect the exhaust gas in a unified manner.

[0027] Breathing valves are mainly used in chromatographs. One is installed in the electrical compartment and one in the furnace of the analyzer. They are mainly used for gas replacement during positive pressure purging of the instrument and can also realize the directional discharge of gas.

[0028] Above, refer to Figures 1-4 A breathing valve according to an embodiment of the present invention is described, which has the following beneficial effects: 1. A circular channel-shaped air inlet 300 is provided on the breathing valve cover 200 to directly limit the flow. The structure is simple and the effect is obvious. 2. Multiple baffles 400 divide the interior of the breathing valve body 100 into an S-shaped meandering channel, so that the gas after flow restriction can achieve the purpose of noise reduction when it passes through.
