Abstract
The utility model relates to a decelerating and boosting static sealing gas valve with an automatic locking, which is composed of a three-way valve body, a valve core, and a valve core driver. The valve core is composed of a circular sheet-shaped valve door, a valve rod, and a guider, one end of the valve rod is provided with a ring with an elliptical hole, the circular sheet-shaped valve door is fixed to the other end of the valve rod, the circular sheet-shaped valve door is corresponding to a valve door hole in the valve body, the valve rod is arranged on an axial position of a valve door hole by the guider, and the middle position part of the valve rod and a sealing soft film are fixed together. The utility model has the advantages of simple structure, high safety, and good tightness.
Description
The utility model relates to the deceleration force amplifier static sealing gas valve that a kind of band automatically locks.
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 a kind of simple in structure, switch valve does not all have the friction process, and has the open and close valve deceleration force amplifier static sealing gas valve that the band of the function of outage locking automatically automatically locks that puts in place then.
The purpose of this utility model is achieved in that it is made up of Three way type valve body, spool and spool driver, spool is made up of disc valve, valve rod, guider, one end of valve rod is provided with the ring with elliptical aperture, the disc valve is fixed on the other end of valve rod, the disc valve is corresponding with the valve hole in the valve body, valve rod is installed in the axial location in valve hole by guider, and the medium position place of valve rod is fixed together with the sealing mantle.
The utility model has the advantages that simple in structure, safe and reliable, can stop the gas leakage problem, its lock function that cuts off the power supply has automatically not only been saved battery consumption, but and the electronic circuit of simplified intelligent controller.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a spool driver control circuit schematic diagram.
By Fig. 1, embodiment shown in Figure 2 as can be known, the utility model is made up of Three way type valve body (1), spool and spool driver, spool is made up of disc valve (3), valve rod (10), guider (4), one end of valve rod (10) is provided with the ring with elliptical aperture, disc valve (3) is fixed on the other end of valve rod (10), valve hole (2) in the disc valve (3) and valve this (1) is corresponding, valve rod (10) is installed in the axial location of valve hole (2) by guider (4), and the medium position place (6) of valve rod (10) is fixed together with sealing mantle (5).
The spool driver is made up of motor, speed reducer, rotating disk (9) and cam pin (11) and two sensitive switches of being positioned on the rotating disk (9), on the outer rim of rotating disk (9), be provided with a finger (13), motor via reducer drives rotating disk (9), cam pin (11) on the rotating disk (9) inserts in the elliptical aperture of valve rod (10) one ends, finger (13) is suitable with two sensitive switches that are positioned at place, rotating disk two edges, alternate 18 ° of two sensitive switches, the power supply of two sensitive switches control motors.
In Fig. 1,2, (12) are the rotating shaft of rotating disk, and (16) are sealed mouth.
Below in conjunction with Fig. 1,2 working principle of the present utility model is described:
Close the valve process: connect K switch 1, the motor M running, cam pin (11) on the rotating disk (9) drives valve rod (10) and moves upward, when valve pass valve puts in place, finger (13) is also just in time sensitive switch (14,15) cutting-off, the motor dead electricity, and all actions of valve stop, be locked in close valve state, disconnect K1 this moment again.
Open the valve process: connect K switch 2, the motor M running, the cam pin on the rotating disk (11) drives valve rod (10) and moves downward, when driving valve and put in place, finger (13) is also just in time sensitive switch (7,8) cutting-off, motor dead electricity, all actions of valve stop, and are locked in out the valve state, disconnect K2 this moment again.
The control circuit of spool driver also can adopt intelligent controller, and it is exactly only for example being assigned in this valve in the IC-card gas meter of intelligent control.
Claims (2)
1, the deceleration force amplifier static sealing gas valve that a kind of band automatically locks, it is characterized in that it is by Three way type valve body (1), spool and spool driver are formed, spool is by disc valve (3), valve rod (10), guider (4) is formed, one end of valve rod (10) is provided with the ring with elliptical aperture, disc valve (3) is fixed on the other end of valve rod (10), disc valve (3) is corresponding with the valve hole (2) in the valve body (1), valve rod (10) is installed in the axial location of valve hole (2) by guider (4), and the medium position place (6) of valve rod (10) is fixed together with sealing mantle (5).
