Abstract

The invention discloses an electric fuel valve device, comprising a motor. The motor is engaged with a driving gear on a pulling fork rod by a driving gear. The top end of a pulling fork rod is inserted by a pulling fork; the top end of the pulling fork is clamped by two clamping platforms of a valve adjusting sheet; the two clamping platforms are clamped on the valve adjusting sheet; the valve adjusting sheet is closely attached to an air inlet port on the valve body. The pulling fork rod is sheathed by a spring which is top pressed on the pulling fork. An installation hole which is arranged on the pulling fork and is inserted with the pulling fork rod is a bar-shaped hole which has the same arrangement direction with the two clamping platforms; the transverse dimension of the bar-shaped hole is identical to that of the pulling fork rod and the longitudinal dimension of the bar-shaped hole is slightly larger than that of the pulling fork rod. A small lug boss is arranged between the two clamping platforms at the top end of the pulling fork; the electric fuel valve device can ensure the sealing and smooth operation of the valve adjusting sheet when being driven by the motor, improves the yield on batch production and reduces cost, thus being widely applied to the fabrication of various fuel valves.

Description

A kind of electric gas valve device

Technical field

The present invention relates to a kind of valve, specially refer to a kind of electric gas valve device.

Background technique

Gas valve on the market is mainly the armstrong's patent valve at present, it mainly is provided with the movable part that is used for valve opening and closing in valve body, be connected with rotary valve rod on this movable part, this valve rod extends to the valve body outside from the valve body top, and be provided with handle, by the handle rotation valve rod, just can realize the opening and closing of valve, the defective of this class valve is that valve rod and handle exceed combustion gas tool surface, oil, the water capacity is easily infiltrated valve internal, influence working life and be difficult to cleaning, in addition, necessary hand switch, not only troublesome poeration during use, but also can not carry out automation control or telecontrol, so be difficult to meet people's usage requirement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of electric gas valve device.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of electric gas valve device, comprise motor, described motor is meshed with actuation gear on the shifting fork bar by driving gear, the shifting fork bar top is plugged with shift fork, the Liang Katai of shift fork top clamping valve regulated valve block, two card decometers are connected on the valve regulated valve block, tight-lipped closely connected the closing of air inlet end on valve regulated valve block and the valve body, be set with the spring of roof pressure on shift fork on the described shifting fork bar, mounting hole with the shifting fork bar plug-in mounting on the described shift fork is a bar hole, bar hole is identical with the arragement direction of two Ka Tai, the transverse dimension of bar hole is identical with the shifting fork bar transverse dimension, the longitudinal size of bar hole is more bigger than shifting fork bar longitudinal size, is provided with small boss between the two card platforms on described shift fork top;

As the further improvement to above-mentioned mode of execution, the air inlet end mouth on the described valve body is provided with the valve regulated valve block groove is installed.

The invention has the beneficial effects as follows: the design makes the valve regulated valve block vertically and in a lateral direction have certain swing space when rotating, make when the valve regulated valve block is close to air inlet end mouth left and right sides circumferential running all the time, angle that again can precise control, in driven by motor, the tightness and the running that can guarantee the valve regulated valve block all the time are smooth and easy, on producing in batches, improve yield rate, reduce cost, thereby can be widely used in the making of various gas valves.

Description of drawings

The present invention is further described for following accompanying drawing.

Fig. 1 is a structure broken away view of the present invention;

Fig. 2 is a valve body structure schematic representation of the present invention;

Fig. 3 is a shift fork worm's eye view of the present invention.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of electric gas valve device, comprise motor, described motor is meshed with actuation gear 11 on the shifting fork bar 1 by driving gear, shifting fork bar 1 top is plugged with shift fork 2, two

card platforms

21,22 of shift fork 2 top clamping valve regulated valve blocks 3, two

card platforms

21,22 are connected on the valve regulated valve block 3, air inlet end mouth 41 on valve regulated valve block 3 and the valve body 4 fits tightly, this product adopts driven by motor shifting fork bar 1 and comes control valve to regulate the rotation of valve block 3 by shift fork 2, thereby realizes the keying of gas valve.

This device can fit tightly on air inlet end mouth 41 in order to guarantee valve regulated valve block 3, be set with the spring 5 of roof pressure on shift fork 2 on the described shifting fork bar 1, in addition, mounting hole 23 with shifting fork bar 1 plug-in mounting on the described shift fork 2 is a bar hole, bar hole and two

card platforms

21,22 arragement direction is identical, the transverse dimension of bar hole is identical with shifting fork bar 1 transverse dimension, the longitudinal size of bar hole is more bigger than shifting fork bar 1 longitudinal size, this design has guaranteed that effectively shift fork 2 is plugged on after the shifting fork bar 1, longitudinal direction has certain swing space, and, the two card platforms 21 on described shift fork 2 tops, be provided with small boss 24 between 22, when valve regulated valve block 3 is placed on two card platforms 21, in the time of between 22, its horizontal direction has certain swing space simultaneously, and more than design makes valve regulated valve block 3 in driven by motor, the tightness and the running that can guarantee valve regulated valve block 3 all the time are smooth and easy, on producing in batches, improve yield rate, reduce cost, thereby can be widely used in the making of various gas valves.
