Abstract
The invention provides a slow-open fast-shutoff mechanism of a motor valve for a gas meter. The mechanism comprises a motor, a reduction box, stem gears and a main support, wherein the stem gears are arranged in the motor and the reduction box; a gear on the stem gear is engaged with the gear in the reduction box; after the shaft end on the stem gear passes through a special hole on the main support, the shaft end is provided with an oval gear, a copper sheathing, a ratchet wheel and a pawl support in sequence, a transition gear is arranged on the other side of the a pawl support; the oval gear and an inner hole of the ratchet wheel are of waist shapes, and when the stem gears rotate, the oval gear and the inner hole rotate homodromously; and a pawl and a pawl spring are arranged inside the pawl support. The slow-open fast-shutoff mechanism of the motor valve for the gas meter is driven through the motor and the reduction box under 6V direct current voltage, thereby leading valve opening to be stable and reliable with small current, and valve shutoff to be reliable and fast. The characteristic of slow-open fast-shutoff well solves the requirement of the gas meter for emergency cutoff of the valve, so the mechanism is a perfect choice for the valve for the gas meter.
Description
Technical field
The present invention relates to a kind of mainly being installed on the intelligent gas meter, the motor valve for gas meter slow-open fast-shutoff mechanism that the use of pipeline gas is controlled.
Background technique
Existing intelligent gas meter valve generally all adopts changing down slowly that approach screw carries out to close mechanism, and so not only switch valve is unreliable, and slow in one's movements, can not satisfy the requirement to gas meter valve emergency cut-off and low power consumption.
Summary of the invention
The objective of the invention is provides a kind of under VDC for the deficiency that solves above-mentioned technology; Through motor and this mechanism's work of speed reducer transmission; Valve is steady, reliable, electric current is little thereby make out, and closes reliably and rapidly motor valve for gas meter slow-open fast-shutoff mechanism of valve.
In order to achieve the above object; The motor valve for gas meter slow-open fast-shutoff mechanism that the present invention designed, it comprises motor, speed reducer, stem gear, main body rack, is provided with stem gear in motor and the speed reducer; Gear engagement in gear on the stem gear and the speed reducer; After axle head on the stem gear passes the special hole on the main body rack, load onto oval gear, copper sheathing, ratchet and ratchet holder successively, and load onto transition gear at the opposite side of ratchet holder; The endoporus of oval gear and ratchet is the waist type, and when stem gear rotated, they rotated in the same way; Ratchet and ratchet spring are equipped with in ratchet holder inside; The shape of engagement in the time of can being rotated in the forward with ratchet is processed in the outer end of ratchet, and the other end is put on ratchet spring and is placed in the ratchet holder; Ratchet spring can guarantee that ratchet and ratchet have certain stretchability when being rotated in the forward engagement.Ratchet rotation when ratchet is rotated in the forward in the engage detent frame during ratchet counterrotating, is withstood by ratchet, thereby is flicked ratchet holder and transition gear.Above part is metallic material except that ratchet holder.
The engagement of the small gear of duplicate gear and tooth bar, gearwheel when driving valve with the transition gear engagement, when closing valve and the transition gear disengagement; The increment of tooth bar and the pinion of duplicate gear, the tooth bar the other end is connected with spring and jam pot cover; When driving valve, the rack drives jam pot cover is up, accomplishes and drives valve, and when closing valve, because under the effect of ratchet and ratchet, duplicate gear and transition gear are thrown off, tooth bar only drives jam pot cover under the effect of spring force descending fast, and moment accomplishes and closes valve.
The resulting a kind of motor valve for gas meter slow-open fast-shutoff mechanism of the present invention, under the VDC of 6V, through motor and this mechanism's work of speed reducer transmission, valve is steady, reliable, electric current is little thereby make out, and closes valve reliably and rapidly.The characteristics of its slow opening fast shutting have solved the requirement of gas meter to the valve emergency cut-off well, and simultaneously, its reliable in function is that gas meter is selected with the ideal of valve in fact.

Embodiment
Combine accompanying drawing that the present invention is done further description through embodiment below.
The motor valve for gas meter slow-open fast-shutoff mechanism that present embodiment is described; It comprises motor 1, speed reducer 2, stem gear 3, main body rack 4; Be provided with stem gear 3 in motor 1 and the speed reducer 2, the gear engagement in gear on the stem gear 3 and the speed reducer 2 is after the axle head on the stem gear 3 passes the special hole on the main body rack 4; Load onto oval gear 5, copper sheathing 6, ratchet 7 and ratchet holder 12 successively, and load onto transition gear 13 at the opposite side of ratchet holder 12; The endoporus of ratchet 7 is a waist shape, and oval gear 5 and ratchet 7 strings are on the axle of stem gear 3, and when stem gear 3 rotations, they rotate in the same way; And with ratchet holder 12 in ratchets 14 engagements.Ratchet 14 and ratchet spring 15 are equipped with in ratchet holder 12 inside; The shape of engagement in the time of can being rotated in the forward with ratchet 7 is processed in the outer end of ratchet 14, and the other end is put on ratchet spring 15 and is placed on ratchet holder interior 12; Ratchet spring 15 is through the other end of ratchet 14, can guarantee that ratchet 14 and ratchet 7 have certain stretchability when being rotated in the forward engagement.When being rotated in the forward out valve; Transition gear 13 meshes with the gearwheel of oval gear 5 and duplicate gear 11; Ratchet 14 rotations in the ratchet 7 engage detent framves 12, when valve was closed in counterrotating, ratchet 7 was withstood by ratchet 14; Thereby flick ratchet holder 12 and transition gear 13, the gearwheel of disengagement duplicate gear 11 under the effect of ratchet 7 and ratchet 14.Above part is metallic material except that ratchet holder 12.
10 engagements of the small gear of duplicate gear 11 and tooth bar, gearwheel when driving valve with transition gear 13 engagements, when closing valve and transition gear 13 disengagements.The pinion of the increment of tooth bar 10 and duplicate gear 11, the other end of tooth bar 10 is connected with spring 8 and jam pot cover 9; When driving valve, it is up that tooth bar 10 drives jam pot cover 9, accomplishes and drive valve, and when closing valve, because under the effect of ratchet 7 and ratchet 14, duplicate gear 11 is thrown off with transition gear 13,10 of tooth bars drive jam pot cover 9 under the effect of spring force descending fast, and moment accomplishes and closes valve.
During work, after the energising of motor 1 forward, drive the gear transmission in the speed reducer 2, thereby mention jam pot cover 9, accomplish and drive valve.After the reverse energising of motor 1, the driven gear transmission because the existence of ratchet 7 and ratchet 14 is arranged, makes transition gear 13 and duplicate gear 11 throw off, and jam pot cover 9 is pressed to valve port in effect following moment of spring 8 power, accomplishes and closes valve.
