Problems solved by technology

When in use, the detection water tank rises and the membrane gas meter remains stationary to realize the membrane gas meter is placed in the water. However, the existing lifting detection water tank has a large lifting resistance, high energy consumption during the lifting process, and stable lifting. Difference

Embodiment 1

[0029] like figure 1 As shown, a detection water tank of a water tightness detection device includes a device body 1, and the detection water tank is installed on the device body 1. During operation, the membrane gas meter is fixed at the position above the detection water tank, and the detection water tank is lifted to make the membrane type The gas meter is placed in water to realize the water tightness detection of the membrane gas meter.

[0030] In order to detect the lifting of the water tank, a lifting drive structure is proposed in the present invention to reduce the lifting resistance and improve the lifting stability.

[0031] Specifically, in a possible embodiment, the detection water tank includes a water tank body 2 and a lift driver 3, the lift driver 3 is installed at the bottom of the water tank body 2, and the lift driver 3 is used to drive the water tank body 2 along the height of the device body 1 direction up and down.

[0032] Lifting drive member 3 comp...

Abstract

The invention discloses a detection water tank of a water tightness detection device, and relates to the technical field of gas meter production equipment. The detection water tank comprises a water tank body and a lifting driving piece, the lifting driving piece is installed at the bottom of the water tank body, and the lifting driving piece comprises a bidirectional output driving motor, an output shaft, a bevel gear set, a lead screw and a sliding block; the two ends of the bidirectional output driving motor are in transmission connection with one ends of the output shafts, the other ends of the two output shafts are connected with the lead screw through the bevel gear set, a lead screw nut pair on the lead screw is connected with a sliding block, and the sliding block is fixedly connected to the outer side wall of the detection water tank. The lifting driving piece composed of the lead screw and the sliding block is arranged to drive the detection water tank to ascend and descend, the lifting stability is good, the sliding block and the detection water tank are guided and slide conveniently in the lifting process in cooperation with the movable limiting block and the ball which are arranged in the limiting groove, and therefore the effects of avoiding lifting deflection and reducing lifting energy consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of gas meter production equipment, more specifically, it relates to a detection water tank of a water tightness detection device. 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] In the existing membrane gas meter water tightness detection device, the membrane gas meter is generally placed in the detection water tank, and the air tightness of the gas meter is detected by injecting high-pressure gas into the gas meter in the water. When in use, the detection water tank rises and the membrane gas meter remains stationary to realize the membrane gas meter is placed in the water. However, the existing lifting detection water tank has a large lifting re...
