Stretch out to realize to the opening of osculum and the operation sealed, waterproof construction is equipped with stretching.
Wherein, the other end of operating parts is also stretched out out of watertight cavity, and waterproof construction also is provided with stretching.
Wherein, transmission mechanism includes the gear and rack being meshed, and power source is the defeated of motor-driven reduction gear box
Shaft, output shaft, which is stretched into watertight cavity, drives the gear to rotate, and rack is located at the portion in watertight cavity of operating parts
Point.
Wherein, groove is equipped with described in the face in watertight cavity at output shaft, output the tip of the axis is inserted into this groove
Positioning.
Wherein, operating parts is equipped with frame-shaped construction in watertight cavity, and rack is arranged on the inner wall of frame-shaped construction, and gear is built in
Among frame-shaped construction.
Wherein, the de- tooth section not engaged with gear is additionally provided with the both ends of operating parts frame-shaped construction upper rack.
Wherein, equipped with elastic component, it exerts a force operating parts when rack starts to depart from gear remote to prevent rack from continuing
Gear.
Wherein, the both ends of operating parts are rod-shaped that the elastic component is arranged on this bar.
Wherein, axial slide guiding operating parts is equipped with watertight cavity to slide axially to operate opening and seal draining
Hole.
Wherein, spool is towards being equipped with mounting hole, the end insertion mounting hole of operating parts in drainpipe.
Wherein, spool valve body and flexible seals being placed on valve body made of with rigid are formed with altogether
It is same to seal osculum.
Beneficial effects of the present invention：
The drain valve of the present invention, by being equipped with the watertight cavity being isolated with drain chamber in drainpipe, and will pass
Motivation structure is located in this watertight cavity, can not only prevent erosion of the current to transmission mechanism, and spool and transmission mechanism are equal
In drainpipe, facilitate transmission mechanism that the power that power source produces is transferred directly to operating parts, the transmittance process of power is stable, can
Lean on, and then spool is axially moved the opening for realizing osculum and is sealed.The drain valve of the present invention is by the way that transmission mechanism is located at
In this watertight cavity, not only play a protective role to transmission mechanism, and make that the structure of drain valve is compacter, and volume is smaller
Ingeniously, and then the installation of drain valve is facilitated.
