Abstract
The utility model designs a slow-opening and fast-closing mechanism of a motor valve, comprising a motor, a speed reduction box, connecting shaft gears and a main body bracket, wherein the motor and the speed reduction box are internally provided with the connecting shaft gears; gears on the connecting shaft gears are meshed with gears in the speed reduction box; shaft ends on the connecting shaft gears are sequentially provided with a connecting gear pawls and a ratchet wheel after penetrating through special holes of the main body bracket; the inner hole of the connecting gear pawl is waist-type, the lower half part thereof is a gear which is meshed with a transitional gear, and the upper half part thereof is a pawl which are internally meshed with the ratchet wheel; the side edge of the ratchet wheel is provided with a small axial protruding table; the small protruding platform is provided with the transitional gear; the connecting gear pawl is meshed with the ratchet wheel to rotate when rotating in a forward direction, and is propped by the ratchet wheel when rotating in a reverse direction, thus flicking the transitional gear. The slow-opening and fast-closing mechanism well meets the requirement on emergent cutting off of a valve from a gas meter due to the characteristics of slow opening and fast closing, simultaneously has reliable function, and is really an ideal selection of the valve for the gas meter.
Description
Technical field
The utility model relates to a kind of mainly being mounted on the intelligent gas meter, to the device that the use of pipeline gas is controlled, particularly a kind of slow-open fast-shutoff mechanism of motor valve.
Background technique
Existing intelligent gas meter valve generally all adopts to change down slowly and closes 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 purpose of this utility model is to provide a kind of under the VDC of 6V for the deficiency that solves above-mentioned technology, by 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 the rapidly slow-open fast-shutoff mechanism of motor valve of valve.
In order to achieve the above object, the slow-open fast-shutoff mechanism of the motor valve that the utility model is designed, it comprises motor, speed reducer, stem gear, main body rack, be 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 special hole on the main body rack, the company's of loading onto tooth papillae pawl, ratchet successively; The endoporus that connects the tooth papillae pawl is the waist type, and its lower half portion is a gear, and with the transition gear engagement, upper half part is a ratchet, and meshes in the ratchet; The side of ratchet has an axial little convex, is adorning transition gear on the little convex; Mesh ratchet gear rotation when even the tooth papillae pawl is rotated in the forward when connecting the counterrotating of tooth papillae pawl, is withstood by ratchet, thereby is flicked transition gear.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 other end of tooth bar is connected with spring and jam pot cover; When driving valve, the rack drives jam pot cover is up, finishes out valve, when closing valve because at ratchet and connect under the effect of tooth papillae pawl, duplicate gear is thrown off with transition gear, tooth bar only under the effect of spring force the drive jam pot cover descending fast, moment is finished the pass valve.
During work, after the energising of motor forward, the driven gear transmission, thus mention jam pot cover, finish out valve.When motor oppositely after the energising, driven gear transmission, owing to ratchet is arranged and connect the existence of tooth papillae pawl, make transition gear and duplicate gear throw off, jam pot cover is pressed to valve port in effect following moment of spring force, finishes the pass valve.
The slow-open fast-shutoff mechanism of the resulting a kind of motor valve of the utility model, the characteristics of its slow opening fast shutting have solved the requirement of gas meter to the valve emergency cut-off well, simultaneously, its reliable in function, real is that gas meter uses the ideal of valve to select.
Description of drawings
Accompanying drawing 1 is a sectional view of the present utility model;
Accompanying drawing 2 is front views that the utility model removes click partial cutaway after the main body cover plate.
Wherein: motor 1, speed reducer 2, stem gear 3, main body rack 4, company's tooth papillae pawl 5, ratchet 6, case 7, spring 8, jam pot cover 9, tooth bar 10, transition gear 11, duplicate gear 12.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1 and Figure 2, the slow-open fast-shutoff mechanism of the motor valve that the utility model is designed, 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, gear engagement in gear on the stem gear 3 and the speed reducer 2, after axle head on the stem gear 3 passes special hole on the main body rack 4, the company's of loading onto tooth papillae pawl 5, ratchet 6 successively; The endoporus that connects tooth papillae pawl 5 is the waist type, and its lower half portion is a gear, and with transition gear 11 engagements, upper half part is a ratchet, with engagement in the ratchet 6; The side of ratchet 6 has an axial little convex, is adorning transition gear 11 on the little convex; Mesh ratchet gear 6 rotations when connecting 5 counterrotatings of tooth papillae pawl, were withstood by ratchet 6, thereby are flicked transition gear 11 when even tooth papillae pawl 5 was rotated in the forward.10 engagements of the small gear of duplicate gear 12 and tooth bar, gearwheel when driving valve with transition gear 11 engagements, when closing valve and transition gear 11 disengagements.The pinion of the increment of tooth bar 10 and duplicate gear 12, 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 covers 9, finishes out valve, and when closing valve, because at ratchet 6 and connect under the effect of tooth papillae pawl 5, duplicate gear 12 is thrown off with transition gear 11,10 of tooth bars drive jam pot cover 9 under the effect of spring force descending fast, and moment is finished the pass valve.
Its endoporus that connects tooth papillae pawl 5 is a waist shape, and string is on the axle of stem gear 3, and when stem gear 3 rotations, it is rotation in the same way also.When being rotated in the forward out valve, transition gear 11 with connect the gear on the tooth papillae pawl 5 and the gearwheel engagement of duplicate gear 12, when valve was closed in counterrotating, transition gear 11 was thrown off the gearwheel of duplicate gears 12 under the effect that connects tooth papillae pawl 5 and ratchet 6.
During work, after the energising of motor 1 forward, drive the gear transmission in the speed reducer 2, thereby mention jam pot cover 9, finish out valve.When motor 1 oppositely after the energising, driven gear transmission, owing to ratchet 6 is arranged and connect the existence of tooth papillae pawl 5, make transition gear 11 and duplicate gear 12 throw off, jam pot cover 9 is pressed to valve port in effect following moment of spring force 8, finishes the pass valve.
