Problems solved by technology

After the membrane gas meter enters the detection water tank, in order to eliminate the air bubbles generated on the surface of the membrane gas meter just entering the water, the existing treatment method in the market is to use a hand-held stirring rod to stir the surface air bubbles to achieve the removal of the surface air bubbles. The operation method not only wastes human resources, but also has low detection efficiency, which greatly slows down the production progress of the enterprise and increases the production cost of the enterprise.

Embodiment 1

[0027] Such as figure 1 As shown, a water tightness detection device for a membrane gas meter includes a device body 1 on which a detection water tank 2 , a lifting drive 3 , a three-way air inlet pipe 6 , and an air inlet and outlet connector 7 are provided.

[0028] The air inlet and outlet connectors 7 include an inlet connector and an outlet connector, and are connected to the air supply equipment through the three-way inlet pipe 6 . The lifting driver 3 includes a lifting cylinder 31 and a lifting console 32 , and the output end of the lifting cylinder 31 is connected to the lifting console 32 . The air inlet and outlet connector 7 is installed on the lifting driver 3, specifically, the inlet and outlet air connector 7 is installed on the lifting console 32, and the detection water tank 2 is installed at the vertical lower position of the inlet and outlet connector 7. Preferably, the lifting cylinder 31 is arranged along the vertical direction of the device body 1 .

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that: Figure 4 As shown, the end of the moving sealing block 114 abutting against the sealing ring 10 is configured as a bevel-shaped structure, and the inclination angle of the bevel-shaped structure is equal to the inclination angle of the bevel-shaped structure on the preliminary sealing block 111 . In this way, it is also convenient for the air inlet and the air outlet of the membrane gas meter to move and abut against the movable sealing block 114, which is convenient for installation.

[0047] The specific implementation principle of the present invention is: when working, first install the air inlet and the air outlet of the membrane gas meter on the air inlet and outlet connector 7, and the lifting driver 3 drives the lifting console 32 to descend, driving the inlet and outlet gas connector 7 With the diaphragm gas meter downwards, until stretching into the water of the detection water tank 2, then vert...

Abstract

The invention discloses a water tightness detection device for a diaphragm gas meter, and relates to the field of gas meter production equipment; the water tightness detection device comprises a device body, the device body is provided with a detection water tank, a lifting driving piece, a three-way gas inlet pipe and a gas inlet and outlet connector, the gas inlet and outlet connector is connected with gas supply equipment through the three-way gas inlet pipe, and the gas inlet and outlet connector is installed on the lifting driving piece; the device body is further provided with a moving seat, an eliminating rod installed on the moving seat, a horizontal movement driving part, a supporting seat installed on the horizontal movement driving part and a vertical movement driving part, the output end of the horizontal movement driving part is connected with the moving seat, and the output end of the vertical movement driving part is connected with the supporting seat. Bubbles on the initial surface of the diaphragm gas meter can be fully automatically eliminated, the detection efficiency can be improved, and the production progress of an enterprise is accelerated; the connection sealing performance is good, and the airtightness detection accuracy is high; in the detection process, the stability is high, and the effect of further improving the detection accuracy is achieved.

Description

technical field [0001] The invention relates to the field of gas meter production equipment, more specifically, it relates to a water tightness detection device of a membrane gas meter. Background technique [0002] Whether there is air leakage in the membrane gas meter is not only related to the interests of users, but also related to the personal safety of users. Therefore, each membrane gas meter must pass a strict airtight test in the production process before leaving the factory. [0003] The existing membrane gas meter airtightness detection device generally puts the membrane gas meter into water, and injects high-pressure gas into the gas meter in water to detect the airtightness of the gas meter. After the membrane gas meter enters the detection water tank, in order to eliminate the air bubbles generated on the surface of the membrane gas meter just entering the water, the existing treatment method in the market is to use a hand-held stirring rod to stir the surface...
