Port, gas outlet and installing port are equipped with valve port, the corresponding valve port between the air inlet and the installing port
Equipped with sealing-plug, the sealing-plug is mounted on the end of a valve rod, is additionally provided with rotation axis on the valve body, the rotation axis with
The output shaft is connected, and the rotation axis end is equipped with hook plate, and the hook plate is equipped with the hook slot of arc shape,
The valve stem end is equipped with prong, is equipped with bearing on the prong, which is articulated in the hook slot.
Turn frame is socketed in the rotation axis, the valve body is equipped with annular corresponding with the turn frame
Chamber, the annular cavity inner sleeve are connected to reset spring, and the end of the reset spring is connect with the turn frame.
Gear is socketed on output shaft on the motor, the valve body is equipped with deceleration corresponding with the gear
Internal gear, the gear are meshed with the internal tooth of the deceleration internal gear, and the deceleration internal gear and the rotation axis are driven
Connection.
The valve port is equipped with close to one end of the sealing-plug and is tilted towards outer open channel, and the sealing-plug is equipped with
The conical surface corresponding with the channel.
Rotation axis rotate driving is driven by using the above-mentioned technical proposal output shaft achieved for having the beneficial effect that motor
Hook slot rotation on hook plate, and then with the up and down of ovable valve stem, the gap size of sealing-plug and valve port is controlled, and then adjust stream
Amount in place, improves the stability of work, just realizes good operating stability and the reliable technical effect of structure in this way.
Embodiment is further described the utility model.
Detailed description of the invention
Fig. 1 is the front view of the utility model；
