Description
The utility model relates to a kind of valve, especially a kind of electric magnetic formula prepay water meter control valve.
Continuous in short supply and scientific and technical continuous development along with water resources, the prepayment domestic water meter has become the problem that water resources management department and user are badly in need of solving, the current control valve that is used for the prepayment domestic water meter, mostly adopt electromagnetic valve structure, promptly according to the actual number of the prepayment of being put down in writing in the control section give control valve a dozen open or close the signal that closes control valve, make the solenoid valve action and realize opening or closing the task of valve.Though the valve of this structure can be realized its task, but because the defective that it has easy misoperation and lacks working life is subjected to certain restriction in application.Also there is employing that control signal is given driving mechanism and driven the technological scheme that stopcock or flat valve action realize opening or closing flat valve or stopcock by driving mechanism, also there is the defective that needs bigger driving force and mostly need external AC power supply in the valve of this structure except that the defective that has stopcock and flat valve itself, so it not only is subjected to the restriction of power supply also to have unsafe factor.
Task of the present utility model is to provide a kind of be active in one's movements reliable, good seal performance, long service life, can uses the electric magnetic type prepay water meter control valve of small-power power.
Task of the present utility model takes following technological scheme to realize, it is at one end to be water intake, one end is that the water outlet and the other end are to be respectively arranged with barrier up and down on the inwall up and down of Three way type valve body of connection mouth, be provided with the leading truck locating piece at the upside of barrier up and down, this leading truck locating piece drops on up and down on the barrier by the valve diaphragm base that is arranged at its downside, downside spiral at the leading truck locating piece is combined with leading truck, this leading truck is provided with guide grab and places up and down between the barrier, on the leading truck locating piece of water intake one side, have the throttle orifice that can be connected with water intake and hydroecium, on leading truck and leading truck locating piece, have and to make water outlet and the hydroecium overflow hole that is connected, its upper end that is threaded on the connection mouth inwall on the valve body has the spill guide pin bushing of plush copper, this guide pin bushing is by being positioned at piston on the leading truck locating piece and leading truck locating piece sealed sliding movingly and make between leading truck locating piece and the guide pin bushing and form hydroecium, be provided with in the Baltimore groove on guide pin bushing can be free to slide therein and to be provided with its lower end of internal magnet in the top be the inner valve sleeve of conical head, the conical head of this inner valve sleeve is located on the sealing gasket that is arranged on the overflow hole upper end-hole, upside thread seal at guide pin bushing is connected with the housing that is positioned with micromachine in the top, the line shaft of micromachine by housing after drive fit have its lower end be provided with guide pin bushing on the equipped mutually screw rod of plush copper, screw-thread fit has the outer valve sleeve that is sleeved on the guide pin bushing outside on screw rod, outer valve sleeve corresponding to the internal magnet place is provided with outer magnetic ring, bottom at outer valve sleeve is provided with guide head, and this guide head places its guiding groove that only can move up and down of qualification that is arranged on the guide pin bushing.
According to technique scheme, when micromachine is received the instruction of opening valve, micromachine is done running clockwise, outer valve sleeve vertically moves upward under the drive of micro motor, the outer magnetic ring that is positioned on the outer valve sleeve moves upward synchronously, move driving on the inner valve sleeve by internal magnet under the effect of outer magnetic ring, hydroecium and overflow hole are connected, liquid in the water intake on the valve body enters in the hydroecium and by overflow hole by throttle orifice and enters back outflow in the water outlet at this moment, in this course since the cross-section area of throttle orifice less than the cross-section area of water intake, make hydraulic pressure in the water intake greater than the hydraulic pressure in the hydroecium, because the existence of this pressure difference, the active force that the liquid of water intake will make progress to leading truck locating piece one, the leading truck locating piece will make it be separated from barrier up and down to top offset under the effect of this active force, this moment the liquid in the water intake by the spatial flow between the guide grab on the leading truck to water outlet, thereby realize opening the task of valve, when micromachine is received the instruction of throttle down, micromachine will be done running counterclockwise, its working procedure is with above-mentioned opposite, thus the task of realization throttle down.
Owing to taked technique scheme, the utlity model has following evident characteristic: the one, owing to adopted the technological scheme of soft cooperation unlatching of magnetic force or throttle down, be active in one's movements reliably good seal performance, the characteristics of long service life so have; The 2nd, owing to adopted micromachine,, can use compact battery as power supply so have low in energy consumptionly as driving source; The 3rd, owing to adopted rotating moving part and the isolated technological scheme of controlled liquid, overcome of the corrosion of controlled liquid, thereby improved its working life and used sensitivity rotary part.
Can effectively realize task of the present utility model in sum.
Below will further describe as follows with reference to the accompanying drawings to the utility model.
