Description

Transmit the built-in gas valve of mechanokinetic with rotating magnetic field

The utility model relates to a kind of with the built-in gas valve of rotating magnetic field transmission mechanokinetic.

At present, the valve in IC-card intelligent gas meter (hereinafter to be referred as table) all is with battery-driven, and is subjected to the control of electronic circuit.Safe handling rule according to combustion gas, the manufacturing of table can run into two problems: the first, or table made " explosion-proof type ", promptly the whole shell seal isolation of using of whole electronic circuits of control table action, but such way not only technology and structure difficulty is big, and cost is also high.Second, table is made " essential safe type ", promptly make the blast tube of table hermetically sealed, guaranteeing that combustion gas does not have extremely leaks, this measure has been removed from explosion-proof processing has been done in electric loop, make on the technology of making a list simple, cost has also reduced, but table will be loaded onto valve control in blast tube, be that valve is in pipeline, its open and close action is finished by machine power, normally transmits the action that opens or closes that mechanical force is finished valve with inserting ducted axle, and the sealing configuration of pipeline is destroyed like this.Although it is very identical that axle can be accomplished with the hole of pipeline, but because the control of table all is micropower (battery) mode, so that coincide and can not do is too tight, otherwise it is motionless that valve is opened (pass), table in use, the axle of valve rubs with the hole one after another, with the passing of time the accident that must cause combustion gas to leak.

The purpose of this utility model provides and a kind ofly simple in structure, safe and reliable, all-sealed transmits the built-in gas valve of mechanokinetic with rotating magnetic field.

The purpose of this utility model is to realize like this, it is by the valve pipe, spool, sealed pipe, the spool driver, permanent magnet, rotating disk and motor are formed, valve pipe and sealed pipe are formed the hermetically sealed valve body of " T " font, the spool driver is contained in the sealed pipe, it is by passive bar shaped blade, speed changer and the thick partially composition of taking turns, speed changer is fixed in the sealed pipe, thick partially the wheel on the output shaft that is contained in speed changer, thick partially prism of taking turns contacts with the guide rod of spool, passive bar shaped blade is contained on the input shaft of speed changer, and passive bar shaped blade is corresponding with permanent magnet across the sidewall of sealed pipe; Rotating disk is contained on the output shaft of motor, and permanent magnet is contained on the rotating disk; Spool is made up of disc valve, cushion rubber, Returnning spring and guide rod, one end of Returnning spring is positioned on the spring seat of valve pipe, being fixedly connected of its other end and disc valve, the opposite side of disc valve is equipped with cushion rubber and guide rod, one end of guide rod passes the areole of sealed pipe, and the disc valve is corresponding with the valve hole in the valve pipe.The material of sealed pipe is the non-magnetic material, and the material of rotating disk and passive bar shaped blade is a magnetic conductive material; Permanent magnet is the 1-2 piece, is preferably two, and the two ends of two blocks of permanent magnets and passive bar shaped blade relatively are installed on the rotating disk.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, the utility model is by valve pipe (1), spool, sealed pipe (6), the spool driver, permanent magnet (11), rotating disk (12), motor (13) is formed, valve pipe (1) is formed the hermetically sealed valve body of " T " font with sealed pipe (6), spool is by disc valve (3), cushion rubber (4), Returnning spring (2), guide rod (5) is formed, one end of Returnning spring (2) is positioned on the spring seat of valve pipe (1), its the other end and disc valve (3) are fixedly connected, the opposite side of disc valve (3) is equipped with cushion rubber (4) and guide rod (5), and disc valve (3) is corresponding with the valve hole in the valve pipe; The spool driver is contained in the sealed pipe (6), the spool driver is by passive bar shaped blade (9), speed changer (8), the thick wheel (7) formed partially, speed changer (8) is fixedly mounted in the sealed pipe (6), thick partially take turns (7) are contained on the output shaft of speed changer (8), the thick partially prism of (7) of taking turns contacts with the guide rod of spool (5), and an end of guide rod (5) passes input shaft (10) that the areole of sealed pipe, passive bar shaped blade (9) be contained in speed changer (8), and to go up passive bar shaped blade (9) corresponding with permanent magnet (11) across the sidewall of sealed pipe (6); Rotating disk (12) is contained on the output shaft of motor (13), and permanent magnet (11) is contained on the rotating disk (12).

The material of sealed pipe (6) is the non-magnetic material, and the material of rotating disk (12) and passive bar shaped blade (9) is a magnetic conductive material.

Permanent magnet (11) is the 1-2 piece, and embodiment illustrated in fig. 1 is two, and it is a strong magnetism magnet, and the two ends of two blocks of permanent magnets and passive bar shaped blade are installed on the rotating disk (12) accordingly.

Working principle of the present utility model is as follows:

Motor (13) in the valve body outside is subjected to the control of smart electronics circuit and rotates, it is being with permanent magnet (11) also to rotate by rotating disk (12), because the passive bar shaped blade (9) of permanent magnet (11) in sealed pipe (6) is very near, so passive bar shaped blade (9) is held also synchronously rotation by permanent magnet (11).The speed change (reduction of speed) of speed changer (8) is than being 300: 1, so, when motor (13) rotation 150 circles, half-turn (promptly changeing 180 °) is just changeed in thick partially take turns (7) that then are contained on the transmission output shaft, when the webbing of thick wheel the (7) partially and guide rod (5) when contacting, thick partially (7) the promotion guide rods (5) of taking turns make gas valve be in opening state, when electronic circuit control motor rotates 150 circles again, half-turn (promptly changeing 180 °) is changeed in thick partially take turns (7), thick partially featheredge of taking turns contacts with guide rod (5), Returnning spring (2) promotes disc valve (3), and gas valve is closed.

The utility model has the advantages that simple in structurely, thoroughly solved the gas leakage problem, greatly improved Safety and reliability is a kind of comparatively ideal gas valve.
