Enter after solenoid valve internal cavity after flowing into valve body internal passage from inlet channel in above-mentioned plug valve by electromagnetism
Valve throttling, after solenoid valve is opened, gas flows to the technique hole path of valve body again by restriction and then flows to valve again
Body bottom cavity enters the ultra-long route in valve core inside channel, is limited by multiple throttle orifices or throttling passage, its gas is caused
Pressure loss when body pressure and flow flow to exit from the entrance of valve body is severe, and flow difference is serious.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of electricity that gas crushing is small for the above-mentioned state of the art
Control plug valve.
The technical scheme of the invention to solve the technical problem is: a kind of automatically controlled plug valve, including
Valve body, inside have valve chamber, offer the air inlet port and outlet passageway communicated with aforementioned valve chamber on the valve body；
Spool is revolvably set in the valve chamber of aforementioned valve body and is adjustable the flow of outlet passageway；
Motor, is set on aforementioned valve body and power output end and spool above-mentioned are drivingly connected；And
Solenoid valve is set on valve body above-mentioned, for the connecting path between on-off air inlet port and outlet passageway；
It is characterized in that there is venting cavity in the middle part of the spool, what the bottom formation of the venting cavity connected with air inlet port
Air inlet, the spool side wall offer the adjusting fire hole communicated with venting cavity, and the adjusting fire hole and aforementioned outlet passageway cooperate
Adjust out throughput；The solenoid valve and motor are respectively arranged on the both ends of valve body, the solenoid valve have one it is electric after can bounce back
Compression bar, the end of the compression bar is equipped with the gasket seal that can open and close aforementioned venting cavity bottom air inlet.
Further, the reset that gasket seal can be driven to seal venting cavity bottom air inlet after power loss is arranged on the compression bar
Spring.
The connection structure of motor and spool is preferably arranged as follows: the power output end of the motor has ring gear, described
Spool be equipped with a valve rod, form the gear teeth being adapted to aforementioned ring gear on the valve rod.
Compared with the prior art, the advantages of the present invention are as follows: the opening and closing end of solenoid valve is directly arranged in the inlet end of spool,
Valve inner gas passage simplifies in this way, and distance shortens, while gas is only needed by a solenoid valve, without repeatedly warp
It crosses, airflow pressure losses substantially reduce, and difference in flow variation also reduces.
