Abstract
Disclosed is an electrically-controlled gas valve. The electrically-controlled gas valve comprises a valve body, a driving gas inlet component, an overpressure gas inlet protective component and a negative-pressure exhaust component. The conversion of the strength of power is achieved by a power assembly through a lever structure, and therefore a low-power double-coil electromagnet can be used for providing the power, and then the power is enhanced at the power output end after the power is transmitted through a rocker arm. Due to the fact that the structure of the power assembly of the driving gas inlet component is optimized, the electrically-controlled gas valve achieves the purpose that a low-power electric component meets the high-power operation requirements, and has the advantages that the on-off power is high, and the working energy consumption is low on the premise that the whole electrically-controlled gas valve is kept being small in size and compact in structure.
Description
Technical field
The present invention relates to a kind of electric-controlled gas valve.
Background technology
In prior art, the aerodynamic force that enters of electric-controlled gas valve comes from frame electromagnet, and electric magnet is provided with mandrel, the core
Axle is fixedly connected with the mover inside electric magnet, and during work, mandrel does straight reciprocating motion, is shown generally as stretching motion.By
In electric magnet mandrel directly with play the part of on-off action and be joined directly together in electric-controlled gas valve, cause switch motion to perform
In journey, power size depends entirely on the rated power of the mandrel of electric magnet.Generally, electric-controlled gas valve is enough to obtain
Big power, and driven using powerful electric magnet.However, existing in use, electric magnet heating is excessive to ask
Topic, causes whole electric-controlled gas valve temperature too high；Meanwhile, powerful electric magnet is sufficiently bulky, therefore, using powerful
After electric magnet, the volume of whole electric-controlled gas valve substantially increases, and reduces its scope of application.
The content of the invention
The technical problem to be solved in the present invention avoids asking for the obvious increase of volume when being and how to obtain larger switching power
Topic, is derived from a kind of small volume and compact, switching power is big, operating power consumption is low electric-controlled gas valve.
To solve above-mentioned technical problem, the present invention is adopted the following technical scheme that：The electric-controlled gas valve includes valve body, actively enters
