Description

Technical Field

[0001] The present invention relates to the technical field of gas meter detection, and in particular to a gas meter membrane quality detection device. Background Art

[0002] The membrane assembly is a key component of the diaphragm gas meter. The membrane assembly is mainly composed of a membrane, a membrane tray, and a membrane plywood. There are two corresponding positioning holes on the membrane and the membrane plywood, and there are two corresponding positioning columns on the membrane tray. After penetrating the membrane and the membrane plywood respectively, the three are welded together by ultrasonic waves. After the three are welded, whether the joints are sealed directly affects the measurement accuracy of the diaphragm gas meter. Therefore, a sealing detection device must be used for testing. Only after meeting the requirements can it enter the next process to ensure that there are no problems with the membrane assembly during product testing and to improve the product qualification rate. There are currently related products to achieve this function, such as the patented gas meter membrane quality detection device with application number CN201811612170.X, which has a high degree of automation, precise placement, and is easy to take and put.

During the reciprocating motion of the second fixed rod 903, only a single stroke of the tooth groove 904 is engaged with the gear 5.

[0044] like Figure 6As shown, as a preferred embodiment, on the basis of the above method, the sealing test mechanism 3 further includes a booster pump 301 fixedly installed on the top of the base plate 1, and an air filling tank 302 is fixedly provided at the air outlet end of the booster pump 301. The inner cavity of the air filling tank 302 is a centrally-through structure, and an air outlet pipe 303 communicating with the inner cavity of the air filling tank 302 is installed at the center of the top of the air filling tank 302. A test tank 304 is fixedly provided at one end of the air outlet pipe 303 away from the air filling tank 302, and a sealing ring 305 is provided on the outer wall of the top of the test tank 304, and symmetrically distributed pillars 306 are fixedly provided between the air filling tank 302 and the test tank 304.

[0049] Specifically, when the gas meter film quality detection device is working: first, the gas film to be detected is adsorbed on the rotating material tray 6 by the provided vacuum suction cup 7, so as to facilitate subsequent detection;

[0050] The eccentric triangular block 12 is driven to rotate by the driving shaft 11. The eccentric triangular block 12 abuts against the inner wall of the abutting square limit frame 905 during the rotation process, thereby driving the second fixed rod 903 to reciprocate. During the reciprocating motion of the second fixed rod 903, only a single stroke of the tooth groove 904 is engaged with the gear 5. When the tooth groove 904 is engaged with the gear 5, the rotating shaft 4 is driven to rotate in the counterclockwise direction. During the rotation process, the gear 5 and the pawl 16 cooperate to prevent it from rotating. Under one reciprocating stroke of the second fixed rod 903, the rotating shaft drives the fixed plate 13 to rotate a certain angle so that the air film adsorbed by the vacuum suction cup 7 moves to the top of the test tank 304. While the second fixed rod 903 is reciprocating, the second fixed rod 903 drives the first fixed rod 902 to reciprocate along the limit frame 901, and then drives the dust brush 25 connected to the vertical rod 24 to reciprocate, thereby realizing the surface cleaning function before the air film test, which helps to improve the test accuracy.

[0051] First, the air is pumped into the inner cavity of the annular tube 802 through the provided air pump 801, thereby dispersing the air into the inner cavities of each telescopic tube 803. The air is then discharged through the air outlet 804 provided on the side wall of the telescopic tube 803, thereby facilitating the cleaning of dust on the surface of the membrane to avoid affecting the test results.

[0052] A hydraulic telescopic cylinder 21 is installed between the bottom plate 1 and the top plate 2 to facilitate adjustment of the height of the top plate 2. When the telescopic end of the hydraulic telescopic cylinder 21 is retracted, the top plate 2 approaches the bottom plate 1, thereby facilitating contact of the film to be tested on the rotating material tray with the sealing ring 305 on the test tank 304. In addition, a telescopic rod 22 and a buffer spring 23 are provided to improve the stability of the device.

[0053] The booster pump 301 is used to boost the gas in the inner cavity of the gas filling tank 302. When the pressure in the inner cavity of the gas filling tank 302 increases, the pressure in the closed space formed by the test tank 304 and the gas film gradually increases until it reaches the standard pressure of the pressure gauge in the gas filling tank 302. Then, the pressure gauge is observed to see if there is any change after a period of rest, so as to judge whether the gas film is airtight or not.

[0054] All technical features in this embodiment can be freely combined according to actual needs.

[0055] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
