[0020] The utility model is further described below in conjunction with embodiments.
[0021] Embodiment 1, as Figures 1 to 5 As shown, the utility model is a breathing valve test and detection device, including a box 12, a gas pipe 13 is fixed on the top of the box 12, the bottom of the gas pipe 13 is closed, the gas pipe 13 is connected to a high-pressure air intake pipe 11, a valve 10 and a pressure gauge 9 are arranged on the high-pressure air intake pipe 11, a connecting flange 18 is fixed on the top of the gas pipe 13, and a plurality of connecting pipes 17 are matched above the gas pipe 13, each connecting pipe 17 is provided with a connecting flange 27 matched with the connecting flange 18 at the bottom end, and a supporting ring 20 matched with the bottom flange of the breathing valve 1 to be tested is arranged on the top of each connecting pipe 17, the supporting ring 20 at the top of the plurality of connecting pipes 17 have different diameters, a sealing ring is arranged on the supporting ring 20, and a clamping mechanism for clamping the bottom flange of the breathing valve 1 to be tested on the supporting ring 20 is arranged on the connecting pipe 17. The air intake pipe 1 is connected to a positive pressure air intake device and a negative pressure air intake device, so that positive and negative pressures can be formed in the pipeline 16 to simulate the breathing gas of the breathing valve.
[0022] According to the size of the breathing valve 1 to be inspected, select a suitable connecting pipe 17 and install it on the top of the air supply pipe 13. When the breathing valve is exhaled, the high-pressure air intake pipe 11 is connected to the positive-pressure air intake device. Then the breathing valve 1 to be inspected is placed on the supporting ring platform 20. The clamping mechanism then clamps the breathing valve 1 to be inspected. The valve 10 is opened, and the positive-pressure air intake device takes in air from the high-pressure air intake pipe 11. It is observed through the pressure gauge 9. When the pressure gauge 9 is below the jump value, the breathing valve 1 to be inspected will jump, which is a qualified product. If the pressure exceeds the jump value and does not jump, it is an unqualified product.
[0023] When testing the breathing valve for inhalation, the high-pressure air intake pipe 11 is connected to the negative-pressure air intake device, and then the breathing valve 1 to be tested is placed on the supporting ring platform 20, and then the clamping mechanism clamps the breathing valve 1 to be tested, and the valve 10 is opened. The negative-pressure air intake device draws air from the high-pressure air intake pipe 11 and observes through the pressure gauge 9. When the pressure gauge 9 is below the starting value, the breathing valve 1 to be tested will start to jump, which is a qualified product. If the pressure exceeds the starting value and still does not jump, it is an unqualified product.
[0024] Embodiment 2, based on embodiment 1, the valve 10 and the pressure gauge 9 are both arranged on the outside of the box body 12.

After placing the breathing valve 1 to be inspected on the support ring platform 20, move the sliding sleeve 18 to the outside, and then move the support ring 5 upward so that the pressure ring 2 is above the bottom flange of the breathing valve 1 to be inspected. Then, the two semi-circular pressure rings 2 cooperate, the positioning protrusion 22 is inserted into the positioning groove, and the pins 23 on the front and rear connecting rods 3 are inserted into the jacks. Then, turn the rotating handle 21 to drive the pressure sleeve 19 to rotate, so that the pressure sleeve 19 moves downward and the pressure ring 2 presses the bottom flange of the breathing valve 1 to be inspected.
