Abstract

An intelligent gas meter induction motor valve with the function of examining the position of valve plug, which comprises a support and a valve plug and a valve tying disposed in the support. A motor seat and a motor is provided on one side of the support, a convex corner is provided at the top of the valve plug, and a magnetic steel is arranged on the convex corner; and a magnetic sensor fitted the magnetic steel is arranged in the support. The utility model has advantages of simple structure, reasonable arrangement, high security of motor valve, assuring the motor valve be fully opened and closed and reliable opening at the time of getting electricity and closing at the time of losing electricity due to providing the position-inducting device which consists of the magnetic steel and the fitted tongue tube, as well low cost and electricity saving etc.

Description

Can detect the intelligent gas meter induction machine valve of valve plug position

Technical field

The utility model relates to a kind of electric machine controller, especially relates to a kind of intelligent gas meter induction machine valve that can detect the valve plug position.

Background technique

At present, existing gas meter adopts the motor valve to control source of the gas mostly, patent retrieval is found, someone has applied for the patent (00217520.7) of " IC-card intelligent gas meter motor valve control " by name, and it is made up of single-chip microcomputer, bridge switching circuit, triode, coil, electrochemical capacitor, diode.The patent (00236744.0) that also has " motor valve " by name, it is that direct current generator is set on common valve, the valve shaft top of its valve is to be the tooth bar of one with valve shaft, this tooth bar is meshed with gear on being fixed on motor, rotate by the direct current generator actuation gear, thus valve plug " unlatching " and " closing " in the driving valve.But this class motor valve exists following deficiency: do not detect the device of valve plug position, can't judge whether opening or closing of motor valve be reliable.

Summary of the invention

The utility model mainly is to solve the device that existing motor valve does not detect the valve plug position, can't judge the technical problem that whether reliably waits that opens or closes of motor valve.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises support and the valve plug, the bibcock that are arranged in the support, and support one side is provided with motor cabinet and motor, and described valve plug top is provided with a salient angle, which is provided with magnet steel; And on described support, be provided with magneto-dependent sensor with the magnet steel phase configuration.

As preferably, described magneto-dependent sensor is a dry reed-pipe, and by the dry reed-pipe box of being located at nearly motor cabinet dry reed-pipe is fixed on the support; Described magnet steel is located in the groove at salient angle place.

As preferably, described magnet steel protrudes from outside the bracket loop; The dry reed-pipe two ends that are positioned on the support are provided with the signal lighting outlet, and are connected on the electronic control plate.

Therefore, the utlity model has simple in structure, rationally distributed, the high safety of motor valve, be provided with the device that induction type that magnet steel and dry reed-pipe match detects the valve plug position, can guarantee that the motor valve opens and closes to put in place, guaranteed that it powers on reliably to drive valve, valve is reliably closed in power down, and has advantages such as cost is low, economize on electricity.

Accompanying drawing 2 is structural representations of Figure 1A-A view;

Accompanying drawing 3 is B-B sectional structure schematic representation of Fig. 2 closed condition;

Accompanying drawing 4 is B-B sectional structure schematic representation of Fig. 2 opening state;

Accompanying drawing 5 is a kind of fundamental diagrams of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: referring to Fig. 1 and Fig. 2, a kind of intelligent gas meter induction machine valve 20 that can detect the valve plug position, structure is that valve plug 2 is set in the support 1, bibcock 3, described valve plug 2 tops are provided with a salient angle, salient angle is provided with groove 16, it is embedded with magnet steel 13, magnet steel 13 protrudes from outside support 1 circle, on support 1, be provided with dry reed-pipe 12 with magnet steel 13 phase configuration, be fixed on the support 1 by the dry reed-pipe box 11 of being located at nearly motor cabinet 9, its two ends are provided with signal lighting outlet 17, and are connected on the electronic control plate 18, support 1 one sides are provided with motor cabinet 9 and motor 7, are provided with motor gear in the motor cabinet 9 and the bibcock gear is meshed.

Its working procedure is as follows: might as well suppose that it is initially in closed condition (referring to Fig. 3), this moment, magnet steel 13 was away from dry reed-pipe 12, when needing to open, electronic control plate 18 gives motor 7 power supplies, motor 7 rotates, be meshed by motor gear and bibcock gear, along with the bibcock gear rotates, bibcock 3 drives valve plug 2 and moves up together, and magnet steel 13 is also close to dry reed-pipe 12, when moving on to the summit on the bibcock 3, magnet steel 13 is near dry reed-pipe 12, the signal lighting outlet 17 at dry reed-pipe 12 two ends sends the signal of valve complete opening to electronic control plate 18, and electronic control plate 18 gives motor 7 outages, motor stall (referring to Fig. 4 and Fig. 5); In the time of need closing, electronic control plate 18 gives motor 7 power supplies, and motor rotates, and is meshed by motor gear and bibcock gear, along with the bibcock gear rotates, bibcock 3 drives valve plug 2 and moves down together, and magnet steel 13 is also away from dry reed-pipe 12, when bibcock 3 moves down into the summit, magnet steel 13 from dry reed-pipe 12 farthest, the signal lighting outlet 17 at dry reed-pipe 12 two ends sends the signal that valve is closed fully to electronic control plate 18, and electronic control plate 17 gives motor 7 outages, motor stall (referring to Fig. 3 and Fig. 5).Thereby realized goal of the invention of the present utility model.
