Abstract
The utility model provides an electromechanical valve, for the anti jam rotary fast shutoff gas meter, which comprises an external shell(1), an external shell cover(13); a motor(2), a lower box(3), an upper box(6), and an upper box cover(10) arranged in the external shell (1); a gear driving means arranged in the lower box(3); an anti jam rotary means and an executing means arranged in the upper box(6). The anti jam rotary means, the gear driving means and the executing means are connected. The electromechanical valve can shut off fast, with the shutoff time less than 0.1s, less power needed for shutting off the valve, and can enhance the safety property and the service life of the gas meter controller; thereby improving the use reliability of the gas meter. The utility model is mainly used for the gas meter with an IC card.
Description
Technical field
The utility model relates to a kind of electromechanical valve, particularly relates to a kind of anti-stall and turn-offs the gas meter special electromechanical valve fast.
Background technique
At present, the IC-card gas meter the electromechanical valve that generally adopts be a kind of fairly simple electromechanical valve, it is directly to drive the slide bar moving linearly by reduction gear and scroll bar.After such electromechanical valve forward and backward puts in place is stall, causes the control circuit electric current big, and power consumption is big, and the reliability of control circuit is relatively poor, and the working life of battery is short, and the pass energy storage that valve adopted electricity value is very big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of Security that increases the gas meter controller is provided, and increases its working life, thereby the anti-stall that improves the gas meter operational safety turn-offs the gas meter special electromechanical valve fast.
The anti-stall of the utility model turn-offs the gas meter special electromechanical valve fast and comprises frame (1) and outer housing cover (13), be arranged on the interior motor (2) of frame (1), following box (3), go up box (6) and upper box cover (10), be arranged on down the gear drive in the box (3), be arranged on anti-blocking rotation mechanism and actuator in the box (6).Anti-blocking rotation mechanism is connected with gear drive and actuator.Wherein, gear drive comprise be installed in down in the box (3) and with the duplicate gear (8) of motor gear (5) engagement, duplicate gear (14) with duplicate gear (8) engagement, duplicate gear (15) with duplicate gear (14) engagement, duplicate gear (4) with duplicate gear (15) engagement, with duplicate gear (4) meshed gears (16), with gear (16) meshed gears (17); Actuator is made up of slide bar (11) and the seal ring (12) that is fixed on slide bar (11) one ends; Anti-blocking rotation mechanism comprises and is arranged in the box (6) and is installed in gear (19) and wobble plate (21) on gear (17) axle, mesh and be fixed on wobble gear (20) on the wobble plate (21) with gear (19), be installed in the box (6) and with the tooth sector (9) of wobble gear (20) engagement, slide bar (11) is connected with tooth sector (9) by eccentric shaft (31), one end of deformed spring (7) inserts in tooth sector (9) groove (30), and the other end is hooked on the interior pillar (29) of box (6).
The working principle that the anti-stall of the utility model turn-offs the gas meter special electromechanical valve fast is, when driving valve, motor gear (5) clockwise rotates, drive duplicate gear (8), (14), (15), (4), (16) reaching (17) clockwise rotates, at this moment, gear (17) clockwise rotates by its gear shaft driven gear (19) and (20), the peripheral force that gear (20) clockwise rotates generation forces wobble plate (21) to rotate around gear (17) axle inhour, gear (20) and tooth sector (9) engagement, thereby drive slide bar (11) to left movement, valve opening, pretension deformed spring (7) simultaneously; Otherwise, when closing valve, motor gear (5) inhour is rotated, drive duplicate gear (8), (14), (15), (4), the rotation of (16) and (17) inhour, at this moment, gear (17) rotates by its gear shaft driven gear (19) and (20) inhour, the peripheral force that gear (20) produces makes wobble plate (21) around the swing of gear (17) axle inhour, gear (20) breaks away from tooth sector (9), because deformed spring (7) discharges pretightening force, force tooth sector (9) inhour rotation fast, move right throttle down thereby drive slide bar (11).
The advantage that the anti-stall of the utility model turn-offs the gas meter special electromechanical valve fast is the valve not stall that puts in place, realize turn-offing fast, shut-in time was less than 0.1 second, it is few to close the required electric energy of valve, stored energy capacitance only needs 1000uF/10V, the Security of using this valve can increase the gas meter controller increases its working life, has also increased the operational safety of gas meter simultaneously.
