Small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve and gas meter

Abstract

The invention provides a small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve and a gas meter, and belongs to the field of gas meters. The small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve comprises a connecting barrel, a sealing cap and a valve core. The connecting barrel is provided with a channel for allowing gas to flow. The channel is provided with an air inlet end and an air outlet end. The air outlet end is installed on the valve core. The sealing cap is located in the channel. A driving mechanism of the valve core is in driving connection with the sealing cap and drives the sealing cap to open or close the air outlet end. The air inlet end of the connecting barrel is used for being connected with an air inlet barrel of the gas meter. The gas meter comprises the small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve. The small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve is small in size, capable of being conveniently installed on the aluminum shell gas meter and closely matched with the aluminum shell gas meter, so that the pressure loss is small, counting is more accurate and reliable, and the application range of the small-size low-pressure-loss type bidirectional non-blocking rotating gear transmission electromechanical valve is extended.

Description

technical field [0001] The invention relates to the field of gas meters, in particular to a small low-pressure loss type bidirectional non-stall-rotating gear transmission electromechanical valve and a gas meter. Background technique [0002] At present, the electromechanical valves used in gas meters generally have three structures. One is that the electromechanical valve rotates in the forward and reverse directions through the motor, and the gear drives the worm. At the same time, the push rod moves in the spiral groove of the worm to realize the opening and closing of the valve. There is no unloading device, and the rotor will be blocked after the forward and reverse rotation are in place, and the load is also relatively large, which will cause a large current in the control circuit and a large power consumption. And it will also affect the reliability of the control circuit of the main controller valve, shorten the service life of the battery in the controller, and the ...
