The invention relates to a device specially used for gas meter airtightness detection. The device is specially used for detecting the seal performance of each gas meter, and is reasonable is structure and accurate in data detection. A stand is provided with placing positions, which are used for placing detected meters; a cylinder body of each lift cylinder is arranged on the stand; each lift cylinder is arranged vertically, and a piston thereof is downward; a lift main frame is fixed to the piston of the corresponding lift cylinder; and a clamping mechanism comprises a lifting support and clamping heads. Each clamping head comprises upper connection pieces, lower connection pieces, clamping pieces, a hinge 1, hinges 2 and a hinge 3, wherein the upper connection pieces are hinged to the lifting support through the hinge 1, and are hinged with the lower connection pieces through the hinges 2 respectively; the lower connection pieces are hinged with the lift main frame through the hinge 3; the clamping pieces are fixedly arranged on the lower connection pieces respectively; and the hinges 2, the hinge 3 and the clamping pieces are arranged in sequence from the up down. Leak detection mechanism detection ports are arranged on the lift main frame. The leak detection mechanism detection ports and the corresponding clamping mechanism are arranged above the corresponding placing position.
Description
technical field [0001] The invention relates to a device specially used for detecting the sealing performance of a gas meter, which is specially used for detecting the sealing performance of the gas meter. Background technique [0002] The gas meter air leakage detection device is used to detect whether there is an air leakage problem in the gas meter, such as the Chinese patent whose patent number is 200810059910.1. The gas meter leakage detection device in the prior art adopts the upper and lower clamping mode to fix the gas meter during detection. Gas meter structure such as Figure 14 As shown, due to the characteristics of the meter under inspection (gas meter), the middle part of the meter is connected by a sealing ring clamped by a hoop. If the upper and lower clamping detection method is used, the detection data in the middle part of the meter under inspection will be incorrect. Contents of the invention [0003] The purpose of the present invention is to overcome...
