Description

Technical Field

[0001] The invention relates to the technical field of gas regulator sealing detection devices, in particular to a gas regulator sealing detection device with a fine-tuning structure. Background Art

[0002] The gas regulator is an automatic pressure regulating device used in the gas supply system of a gas engine to provide the engine with gas with stable pressure. Figure 1 As shown, a gas regulator assembly 7 generally includes a shell, an air inlet 12 arranged on the shell, an air inlet valve seat 3 tightly mounted at the rear of the air inlet 2, a rocker arm assembly 4 mounted in the shell, and an air outlet interface, wherein a sealing gasket 11 is mounted on the rocker arm assembly 4 for sealing the mouth surface of the air inlet valve seat 3 when the machine is shut down. During the production process of this type of gas regulator assembly 7, due to the existence of processing errors, the joint surfaces of the sealing gasket 11 and the mouth surface of the air inlet valve seat 3 are often not parallel, so there is a leak due to poor sealing. Therefore, after the gas regulator assembly 7 is assembled, it is necessary to perform 100% sealing inspection and adjustment on the gas regulator assembly 7. At the same time, in order to simplify the adjustment, the length of the air inlet valve seat 3 is generally designed to be a negative tolerance. That is, during adjustment, it is only necessary to move the intake valve seat 3 towards the sealing gasket 11 until the sealing gasket 11 and the joint surface of the intake valve seat 3 are parallel and tightly joined. In the prior art, during detection and adjustment, the intake port 2 of a gas regulator assembly 7 is usually connected to compressed gas of a set pressure, the pressure is maintained and the leakage is observed, and then the operator uses a rod-shaped tool to knock the intake valve seat 3 towards the sealing gasket 11. This requires a very high technical level of the operator. If the knocking is too little, it is necessary to repeat the detection and knocking, and it must be adjusted after repeated attempts. Once the knocking amount is too large, it is necessary to disassemble the gas regulator assembly 7 as a whole, withdraw the intake valve seat 3 outward by a certain distance, and then reassemble other components, and then detect and adjust the sealing, which has low productivity. Summary of the invention

[0003] The purpose of the present invention is to provide a gas regulator sealing detection device with a fine-tuning structure, which has the advantages of easy operation, fast detection and adjustment speed, high production efficiency, and low requirements on the technical level of operators, thereby solving the problems in the prior art.

[0014] Beneficial effects of the present invention: the present invention provides a gas regulator sealing detection device with a fine-tuning structure. When in use, the gas regulator assembly is fixed on a fixture, and then one end of the cavity opening of the adjustment seat is pressed and contacted with the air inlet end face of the gas regulator assembly, so that the push rod is extended into the air inlet and abuts against the air inlet valve seat, and then compressed gas of a specified pressure is introduced through the air pipe, and the indication of the air flow meter is observed. If it is not zero, it indicates a leakage. At this time, the screw is rotated into the adjustment seat, and under the action of the cone part, the push rod is pushed forward to push the air inlet valve seat toward the sealing gasket until the indication of the air flow meter is zero, indicating that the adjustment is in place. It has the advantages of convenient operation and fast detection and adjustment speed, which significantly improves production efficiency and reduces the requirements on the technical level of operators.

In this way, when the gas regulator assembly 7 is installed on the fixture, the adjustment seat 6 is aligned with the end face of the air inlet 12 so that the push rod 2 extends into the air inlet 12, and the adjustment seat 6 is quickly pressed against the end face of the air inlet 12 with the quick clamp 9, so that the adjustment seat 6 generates a pressing thrust through the quick clamp 9 to contact and cooperate with the end face of the opening of the cavity 601 of the adjustment seat 6 with the end face of the air inlet 12 of the gas regulator assembly 7. After the detection and adjustment are completed, the quick clamp 9 can be loosened to conveniently remove the adjustment seat 6 and the gas regulator assembly 7, and the operation is convenient and quick.

[0019] Preferably, a pressure gauge 14 is also installed on the air pipe 15, so that it is convenient to observe whether the pressure value of the compressed gas in the air pipe is within the specified requirements.
