The on-off valve is completed.

Further, the valve body and the valve body air inlet connecting pipe are fixedly connected through screws. The valve body air inlet connecting pipe and the valve body are separated into two parts, and the valve body air inlet connecting pipe only needs to be replaced according to the sizes of the air inlet and the air outlet of different gas meters.

Furthermore, a valve cover is arranged outside the valve mechanism cavity. The transmission mechanism is used for protecting the valve.

Furthermore, the sleeve is made of stainless steel.

Further, the valve clack is a spherical clack. When the valve is opened and closed, the valve rod in the meter, the valve rod outside the meter and the valve clack only need to rotate 90 degrees, and the valve can be opened and closed.
