Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Gas meter valve Hermetical connecting structure as depicted in figs. 1 and 2, including motor valve, for control gas flow
Valve body 1 and the connector 2 for being fixed on shell of gas meter admission line, valve body 1 include that gas outlet 12 is connected with same connector 2 into
Gas port 11, connector 2 are hollow tubulose, and valve body 1 is closed to be set in outside connector 2, the air inlet 11 of valve body 1 can between cover
It is located at outside connector 2, plays the role of the two mutual cooperation and connected.
Fig. 3 is the enlarged drawing at A in Fig. 2, and 2 outside of connector as shown in Figure 3 is equipped with the card-bit part protruded along 1 direction of valve body
32, the air inlet 11 of the valve body 1 is equipped with fixing piece 31, is equipped between the fixing piece 31 and valve body 1 and is worn for card-bit part
The screens slot 33 crossed, the one end passed through from screens slot 33 on the card-bit part 32 are equipped with convex for preventing card-bit part 32 from coming off
It rises.The protrusion is located at one end that card-bit part 32 passes through fixing piece 31, and raised position is just stuck on fixing piece 31 so that valve body 1
It will not be detached between connector 2.
