Description

Technical Field

[0001] The utility model relates to a diaphragm inspection and repair device for a low-pressure regulator for gas, belonging to the technical field of gas valves. Background Art

[0002] Fatigue failure of the pressure regulator diaphragm is one of the important reasons for the effectiveness of gas pressure regulating facilities. The diaphragm is mostly made of rubber products, and there are two forms of failure: fatigue failure and aging failure. As a key component of gas pressure regulating equipment, the diaphragm plays the role of pressure transmission, balancing medium and driving the movement of fuel. Under normal operating conditions, due to the dynamic load on the diaphragm, fatigue deformation or fracture will occur, resulting in diaphragm failure, affecting or destroying the user's gas equipment and affecting the user's gas safety. Therefore, a low-pressure regulator diaphragm maintenance device is studied for diaphragm failure detection. Utility Model Content

[0005] Preferably, a sealing rubber ring is provided between the mounting seat and the detection seat, and the sealing rubber ring is made of silicone material.

[0006] Preferably, fixing holes are provided on both sides of the lower portion of the mounting seat, and correspondingly, bolt holes are provided on both sides of the detection seat, and fixing bolts are installed in the fixing holes and the bolt holes.

[0007] Preferably, the pressure adjusting rod includes a lifting screw, a telescopic rod and a pressure adjusting spring.

[0008] Compared with the prior art, the utility model has the following technical effects: the utility model can place the membrane to be tested on the membrane detection groove of the detection seat, connect the mounting seat and the detection seat by bolts, and inject gas into the membrane detection groove. If the membrane leaks excessive gas, the gas leakage alarm will sound an alarm, and the detection is simple and convenient. At the same time, the pressure of the pressure regulating rod is adjusted to the preset pressure when the membrane is in operation.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0012] like Figure 1 and Figure 2 As shown, a diaphragm inspection and maintenance device for a low-pressure regulator for gas comprises a mounting seat 1 and a detection seat 2, the mounting seat 1 is mounted on the detection seat 2, a diaphragm detection groove 3 is arranged on the detection seat 2, an air inlet pipe 4 is arranged on one side of the diaphragm detection groove 3, and an air inlet interface is installed on the air inlet pipe 4, and a detection tube 5 is arranged on the other side, a pressure gauge 6 and a control valve 7 are installed on the detection tube 5, and an air outlet interface is arranged at the end, the air inlet pipe 4 and the detection tube 5 are respectively connected with the diaphragm detection groove 3, a pressure regulating rod 8 is installed on the mounting seat 1, a diaphragm limit ring 9 is installed on the pressure regulating rod 8, and a leakage channel 10 connected with the diaphragm detection groove 3 is also arranged on the mounting seat 1, and a gas leakage alarm 11 is installed on the leakage channel 10.

[0013] The utility model adopts a mounting seat 1 and a detection seat 2. The lower sides of the mounting seat 1 are provided with fixing holes 13. Correspondingly, the two sides of the detection seat 2 are provided with bolt holes 14. The fixing holes 13 and the bolt holes 14 are provided with fixing bolts 15.
