Abstract
Disclosed is a driving valve for a motor of an IC card gas meter, which has the advantages of non locked rotating, low power consumption and high reliability. A valve core of the valve is arranged on an opening-closing seal port (14) which is arranged on one side of an air-intake cavity of a valve body, and a flexible pushing structure of a valve rod can produce meshing-detaching slipping between a pushing gear (3) and a sliding gear column (10) when the opening and closing of the valve body are in proper position. The valve is characterized in that the sealing is more reliable utilizing gas pressure without reacting force after closing; and the situation of high power consumption due to locked rotating can not occur in the valve opening and closing process of the motor; and ineffective power consumption of moving elements is low, therefore a low-power driving motor can be adopted; and the valve has light components which can all be processed with low cost; and the moving elements are isolated from the gas, therefore having good noncorrodibility.
Description
The utility model relates to a kind of control valve structure of IC-card gas meter, is specifically related to a kind of motor-driven valve (hereinafter to be referred as the motor valve) of IC-card gas meter.
In the IC-card gas meter, adopt the motor valve, now become a kind of topmost structural type, alleviate operating cost in particular for the user, adopt disposable built-in lithium battery to finish under the requirement of the whole Life cycle electricity consumption of IC-card gas meter, a kind of do not have the highly reliable requirement to the motor valve of stall low power consumption and be suggested.This is the problem that the production firm of IC-card gas industry and designer are concerned about and solve to power.
It is reliable that the purpose of this utility model provides a kind of keying, the technological scheme of no stall, low power consumption, low cost, IC-card gas meter motor actuating valve that anticorrosion structure is good.
For achieving the above object, the technical solution of the utility model is: adopt to have the flexible spool that promotes structure, the valve rod of spool passes from the outlet chamber and the sealed mouth of valve body, and an end that is positioned at the air-inlet cavity side at valve rod is provided with valve seal.
In the technique scheme, described flexible to promote structure be suit slide teeth post on valve rod, on the valve rod at the two ends of slide teeth post be fixed in pocketed springs between the ring washer on the valve rod, the slide teeth post with promote gear engagement.
In the technique scheme, described valve rod partly and between the valve body is being provided with seal membrane outside the valve body.
Working principle of the present utility model is: motor drives with worm type of reduction gearing and promotes gear, promotes the slide teeth post on the gear promotion valve rod, and the slide teeth post promotes valve rod by being placed on the valve rod and spring and the ring washer that is fixed on the valve rod coaxial with valve rod.Valve rod passes from the outlet chamber and the sealed mouth of valve body, is positioned at an end of air-inlet cavity side at valve rod, drives rubber seal cushion opening-closing motor valve by the drive lid of holding one's breath.In the process that opens and closes the motor valve, when rubber gasket is in the motor valve and opens and closes the position put in place, the slide teeth post can continue owing to the compressibility of spring along valve stem slides, to increase the pressure of spring, skid up to the elasticity that promotes the out-of-gear minor swing of appearance between gear and the slide teeth post, because the latching characteristics of worm-and-wheel gear, so tooth position with the co-axially fixed promotion gear of worm gear, relative fixed when the motor stall, when motor controlled and when stopping operating, the slide teeth post can keep the stable of last tooth to contact with the promotion gear, and its position on valve rod is also definite relatively, therefore can keep the keying state of motor valve.Meanwhile, seal membrane all can carry out effective isolation with motor valve dirivig member to combustion gas.
The advantage that the utility model had:
1, when the motor valve cuts out, the pressure that the pressure of air-inlet cavity is higher than outlet chamber can utilize the pressure difference on the rubber gasket, valve closed force is increased, thereby make sealing more reliable.
2, the motor valve opens and closes when putting in place, and drive motor does not have stall, and the big power consumption of not having big electric current occurs, and therefore can not burn out motor, can not cause the stressed damage of member.
3, the guiding distance of valve rod, it is stuck can not self-locking to occur, and the ineffective power consumption of operation is few, and reliability increases, and also can adopt the small-power drive motor.
4, dirivig member and combustion gas are effectively isolated, anti-corrosive properties are good.
5, dirivig member is stressed little, can design smaller and more exquisitely, therefore can reduce production costs.
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Accompanying drawing 1 is the utility model, the generalized section of motor valve when opening
Describe the details and the working condition of the motor valve that the utility model proposes in detail below in conjunction with accompanying drawing.
Motor valve shown in the accompanying drawing 1 is by having air-inlet cavity (15), the valve body (1) of sealed mouth (14) and outlet chamber (2), promote gear (3), worm gear (4), worm screw (5), motor (6), support (7), ring washer (8) and (12), spring (9) and (11), slide teeth post (10), seal membrane (13), the lid (16) of holding one's breath, valve rod (17), rubber gasket (18) is formed, wherein by valve rod (17), the lid (16) of holding one's breath, rubber gasket (18), the slide teeth post (10) that can on valve rod, slide, spring (11) and (9) are fixed on the flexible spool that ring washer (8) on the valve rod and (12) are formed, and the direction of gas flow is that arrow A is to arrow B during opening of valves.
The motor valve is in closed condition among the figure, the structural relation of anticipating shown in the figure is: motor (6) promotes worm gear (4) by the worm screw (5) on its output shaft, again by promoting slide teeth post (10) with the co-axially fixed promotion gear of worm gear (4) (3), can go up the slide teeth post (10) that slides at valve rod (17), promote spring (9) or (11) simultaneously, promote to be fixed in ring washer (8) or (12) on the valve rod by spring (9) or (11) again, drive seal disc (16) and rubber sealing gasket (18) keying motor valve thereby promote valve rod (17).Outer O type ring portion part on the seal membrane among the figure (13) is fixed on the valve body (1) by frame (7), and O type ring portion part is fixed on the valve rod (17) in it.Figure medi-spring (9) is in compressive state, and the tooth of an end of slide teeth post (10) is in metastable position with a tooth that promotes gear (3).All with elastic pressure seal sealed mouth (14) valve body (1) on successively by ring washer 8, valve rod (17), the lid (16) of holding one's breath, rubber gasket (18) for the thrust of spring (9).
