[0006] The buckle position of the gas meter includes a buckle groove and a non-return spring sheet release groove, which are arranged on the gas meter in sequence according to the rotation direction of the motor valve. The opening direction of the buckle groove faces the rotation direction of the motor valve, and the opening direction of the non-return spring sheet release groove faces the side with the buckle groove on the connecting plate;

[0007] When the support column completely enters the bottom of the buckle groove, the other end of the anti-return spring sheet enters the anti-return spring sheet release groove at the same time; a stop point is provided at the end of the anti-return spring sheet release groove to prevent the anti-return spring sheet from escaping from the anti-return spring sheet release groove.

[0008] Preferably, the motor valve buckle position is arranged on the valve port of the motor valve, and the support column is fixed on the valve port of the motor valve 1; the gas meter buckle position is arranged on the connecting plate of the gas meter housing, and the buckle groove, the check spring release groove and the stop point are arranged on the connecting plate in sequence according to the rotation direction of the motor valve.

[0009] The utility model is simple to install and easy to operate, and can meet the needs of automatic installation of motor valves. The motor valve only needs to insert the valve port into the inner hole of the joint of the gas meter, rotate the motor valve body, and the motor valve buckle position on the motor valve port will automatically slide into the gas meter buckle position on the connecting plate on the shell, so as to realize the rapid installation and fixation of the motor valve and improve the installation efficiency of the motor valve and the gas meter.

[0018] To make the present utility model more obvious and understandable, a preferred embodiment is hereby described in detail in conjunction with the accompanying drawings as follows.

[0019] The present utility model provides a screw - free installation structure for a motor valve of a gas meter. As Figures 1 - 8 shown, it includes a motor valve 1 and a gas meter 2. At least two motor valve buckling positions 1 - 3 are provided on the valve port of the motor valve 1, and gas meter buckling positions 2 - 1 with the same number and matching are provided on the connecting plate 2 - 5 of the housing of the gas meter 2.

[0020] The motor valve buckling position 1 - 3 includes a support column 1 - 1 and a non - rebound sheet 1 - 2. The support column 1 - 1 is fixed on the valve port of the motor valve 1. One end of the non - rebound sheet 1 - 2 is fixed on the support column 1 - 1 and is located on the rotation side of the support column 1 - 1 when the motor valve 1 rotates. The non - rebound sheet 1 - 2 is inclined relative to the support column 1 - 1.

[0021] The gas meter buckle position 2-1 includes a buckle groove 2-3, a non-return spring piece release groove 2-4, and a non-return point 2-2. The buckle groove 2-3, the non-return spring piece release groove 2-4, and the non-return point 2-2 are sequentially arranged on the connecting plate 2-5 according to the rotation direction of the motor valve 1. The opening direction of the buckle groove 2-3 faces the rotation direction of the motor valve 1. Behind the buckle groove 2-3 (according to the rotation direction of the motor valve 1), there is a non-return spring piece release groove 2-4 for keeping the non-return spring piece 1-2 in a free state (i.e., the state of releasing the elastic force). The opening direction of the non-return spring piece release groove 2-4 is upward (i.e., towards the side of the connecting plate 2-5 with the buckle groove 2-3). Behind the non-return spring piece release groove 2-4 (according to the rotation direction of the motor valve 1), there is a non-return point 2-2.

[0022] When the support column 1-1 completely enters the bottom of the buckle groove 2-3, the other end of the non-return spring piece 1-2 simultaneously enters the non-return spring piece release groove 2-4, and the non-return point 2-2 at the rear end of the non-return spring piece release groove 2-4 prevents the non-return spring piece 1-2 from coming out.

[0023] The installation process of the present utility model is as follows:

[0024] Insert the valve port of the motor valve 1 into the inner hole of the joint of the gas meter 2, and rotate the valve body of the motor valve 1. The motor valve buckle position 1-3 on the valve port of the motor valve 1 will automatically slide into the gas meter buckle position 2-1 on the connecting plate 2-5 of the gas meter 2 housing, realizing the installation and fixation of the motor valve. Specifically: The support column 1-1 on the valve port of the motor valve 1 slides into the buckle groove 2-3 on the connecting plate 2-5 of the gas meter 2. At the same time, the non-return spring piece 1-2 on the valve port of the motor valve 1 overcomes the elastic force and slides into the non-return spring piece release groove 2-4 of the gas meter 2, and the non-return point 2-2 prevents the non-return spring piece 1-2 from coming out.
