Abstract
A gas meter electronic internal valve comprises a motor mounted on the motor cover, a motor bracket cover and in a cover shell, a push rod with a transmission rod is connected with a movable seal ring, a rubber seal block to construct an actuation mechanism, an upper gear of a motor shaft is meshed with a gear wheel on one end of a spiral rod, the spiral rod is connected with a bracket through a positioning pin to construct a transmission mechanism, the transmission mechanism is integrally connected with the actuation mechanism through the transmission rod and a guiding shaft to be fixed on the motor, the push rod and the bracket are connected with a locking mechanism composed of an upper magnetic block and a lower magnetic block, a press block is mounted on the outer ring of the movable seal ring, the press block is fixed on the end surface of the motor bracket cover through a screw, and the motion direction of the push rod is vertical to the gas inlet port direction. The gas meter electronic internal valve has simple structure and high valve opening and closing speed, the locking mechanism not only facilitates the moving, positioning and resetting of the push rod, but also has locking function, namely the magnetic blocks can suck with each other as the power outage occurs or the push rod is not in position, thereby ensuring the sealing and use safety of the valve. The valve gas path and the valve interior structure are completely separated, and the pollution of the pipeline to the valve is radically solved.
Description
Technical field
The utility model relates to a kind of being installed in the IC-card intelligent gas meter, the keying of pipeline gas is controlled the automatically controlled built-in valve of gas meter of use.
Background technique
The patent No. 200720112502.9 " the built-in valve of gas meter ", rotate by motor driven gear, make the click parts turn to bevel gear pair, thereby drive the bevel gear pair rotation, bevel gear pair drives tooth bar at last and the jam pot cover assembly is done to finish out valve away from the motion of valve port, opposite motor driven gear counter-rotating makes the click parts throw off bevel gear pair, finishes and closes thereby make tooth bar and jam pot cover assembly press to valve port rapidly under the effect of awl spring force.Adopt traditional gear train as reducing gear, through tooth bar the straight line motion that the rotation of gear train becomes tooth bar is reached the purpose that opens and closes gas valve again, but its part is many, gear is many, transmission speed is slow.
The patent No. 200520014714.4 " the Worm type motor valve of threading off certainly ", though the engagement of a kind of upper gear of motor shaft and gearwheel is provided, be connected with worm screw on the gearwheel and pull out tooth, fixing guide pin on the support, cantilever tip is with rubber top plug, guide pin inserts in the teeth groove of worm screw, motor rotates and drives gearwheel, pull out tooth, worm screw is rotated, worm screw is rotated and drives on the support, move down, thereby it is opening/shutting valve, though simple in structure, part is few, but above-mentioned patent does not also have locking function, if dead electricity, it is just poor that support moves the sealing of valve port not in place, will directly influence Security and the reliability that gas valve uses.
Summary of the invention
Technical problem to be solved in the utility model is: provides a kind of gas meter automatically controlled built-in valve, has locking function, and safe and reliable, it is simple in structure, part is few, easily processing, easily assembling, and gas meter valve keying speed is fast, and better tightness is practical.
The technical scheme in the invention for solving the above technical problem is: the automatically controlled built-in valve of gas meter, comprise and be installed in electrical machinery cover, the electric machine support cover, motor in the case, by connecting the movable sealing circle on the push rod of band drive link, the actuator that the rubber seal piece constitutes, gearwheel engagement by upper gear of motor shaft and spiral rod end, screw rod is connected by locating stud and constitutes driving mechanism on the support, and drive link, the axis of guide connects into overall fixed on motor with driving mechanism and actuator, also be connected with on described push rod and the support, following magnetic patch constitutes locking mechanism, briquetting is installed at place, movable sealing circle outer ring, briquetting is screwed on the end face of electric machine support cover, and the pushrod movement direction is vertical with the suction port direction.
Compared with prior art, advantage of the present utility model is: driving mechanism directly is made of gear on the motor shaft and gearwheel engagement by the rack-mount spiral rod end of locating stud, it is simple in structure, the a plurality of gear parts in the gear transmission group have been saved, small volume structure compactness again, processing cost is low.Also fasten the movable sealing circle, make it be fixed on the electric machine support cover not only good airproof performance, gas circuit and valve inner structure are separated fully, thoroughly solve of the pollution of pipeline impurity the valve internal structure with pressing plate.Corresponding upper and lower magnetic patch is installed in the through hole of push rod and support, remove be convenient to the moving of push rod, directed, reset, also having locking function simultaneously can lock valve port more firm, be dead electricity or push rod magnetic patch can automatic adhesive sealing when putting in place, guarantee push rod be stabilized in close or the opening state position on.Fuel gas inlet and outlet are orthogonal, and the impurity in the combustion gas enters and can sink in the case at the bottom of the case, and pile up at the sealed mouth place that can not rest on gas valve, reduces the pressure loss, guarantees the gas smoothness.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
One side of push rod 10 is a sash, and opposite side is a straight-bar, and the blind hole in sash and straight-bar jointing place is embedded with drive link 7, and the through hole of push rod 10 sashes one end face two edges is embedded with down magnetic patch 17.
In the middle of the screw rod 6 through hole is arranged, there is spiral chute on the surface, and there is gearwheel 13 lower end.
The push rod 10 and support 3 usefulness two axis of guides 5 connect into whole driving mechanism and actuator, and the support lower face is screwed on the end face of motor 2, and make gearwheel 13 engagements of gear 4 and screw rod 6 ends on the motor shaft.
During use, motor 2 energisings, motor driven gear 4 also drives screw rods 6 by the gearwheel 13 with its engagement and rotates, stir helicoid by the drive link 7 in the insertion screw rod 6 and make the transmission working surface, the rotation of screw rod 6 is become push rod 10 parallel moving to the right, the rubber seal piece 11 that drives simultaneously on it moves right, up to the sealing of valve port end is stabilized in closed condition, as shown in Figure 1, 2.
If motor backward rotation, then gear 4 drives gearwheel 13, screw rod 6 backward rotation, direction is parallel mobile left to drive push rod 10 by drive link 7, while is activity compression seal ring 9 also, the spiral chute destination county that forwards the screw rod the other end up to drive link 7 to is stabilized in opening state, at this moment gas meter is given vent to anger from valve port after the top air inlet is turned, as shown in Figure 3.
The locking mechanism that upper and lower magnetic patch 18,17 constitutes is installed on support 3, the push rod 10, make support 3, push rod 10 adhesives firm, then rubber seal piece 11 sealing combustion gas valve ports stablize firm, good airproof performance, if it is not in place that dead electricity or push rod move, locking mechanism adhesive automatically puts it in place, holds out against rubber seal piece 11 and valve port jointly by support and push rod close proximity, strengthen the sealing and the locking property of valve, practical.
