Abstract
The utility model provides a self-closing water-saving valve, which is characterized in that the valve body is a vertical valve body (1); the valve core is a sealed ball (2) which is arranged in an upper hole of the valve body (1) and is in tight movable fit connection with a spherical segment concave hole of the valve body (1); a control rod (3) is connectively inserted in the valve body (1) on the lower part of the sealed ball (2); a positioning pin (4) is arranged on the control rod (3) which is orientationally connected with the valve body (1); the top end of a lug boss in the middle of the control rod (3) is contacted with the sealed ball (2). The self-closing water-saving valve has the advantages of simple structure, easy production, water resource saving effect, long service life, good economic and environmental benefits in public water consumption sites, and good water resource saving effect.
Description
Technical field the utility model is a mechanical engineering technical field, relates to the valve of fluid control switch.
Mostly the control valve for fluids that background technique is general is to be connected to form by the taper valve core or the flashboard type spool of valve body and band spiral link rod.It realizes the opening and closing of valve movingly by seat hole in rotating link regulating spool and the valve body.Its shortcoming is that working life is short, and switch is loaded down with trivial details because the connecting thread of the screw rod of water valve and valve body and seal element are easy to damage.Another shortcoming is when throttle down, closes the rundown process fluid from large to small, can not close immediately, and the process from large to small of current forms unnecessary waste.Especially in public places waste is serious, and what have does not tightly cause running water phenomenon, waste water resource because of closing.
Summary of the invention is at above-mentioned shortcoming, and the utility model provides a kind of self-closing water-saving valve, realizes that switch is convenient, long service life, and the water-saving valve of in time closing voluntarily after the water is saved water resources.The utility model is achieved in that adopting ball sealer is closure member, be installed in the vertical valve body and and be connected movingly closely with the segment shape shrinkage pool formation at valve body middle part, the horizontal company of inserting controlling rod on the valve body lower portion body wall, the controlling rod middle part is provided with boss and touches even ball sealer composition.The controlling rod of this valve is a fulcrum with the blind hole of valve interior wall, and when the guide groove of picking-up controlling rod on valve body moved up, the middle protuberance jack-up ball sealer of controlling rod broke away from friction tight segment hole, with opening of valves.After finishing, hand is from controlling rod, and controlling rod is along the guide groove free fall of valve body, and simultaneously, ball sealer is because of water pressure and self gravitation, and return is with the sealing of the through hole in the valve body thereupon, and valve is just closed voluntarily.
The utility model has the advantages that simple in structurely, manufacturing process is simple and easy, and is easy to use, and application life is long.Because of this valve is a Normally closed type, with after in time close voluntarily, save water resources, be widely used.Especially in public water place, more can embody its economic value and environmental value.
Description of drawings Fig. 1 is the sectional view of the utility model structure.
Embodiment
As shown in Figure 1, the utility model is by valve body (1), and ball sealer (2) and controlling rod (3) and locating stud (4) are formed.Valve body (1) is vertical valve body, and ball sealer (2) is a spool.Ball sealer (2) is installed in the last aperture of valve body (1) to form with the segment shape shrinkage pool of valve body and is connected movingly closely.Controlling rod (3) is laterally inserted the blind hole of vicinal on ball sealer (2) lower body (1) by the guide groove of valve body (1), and locating stud (4) is housed on controlling rod (3).Controlling rod (3) and valve body (1) are located by connecting.The body of rod middle part of controlling rod (3) is provided with boss, the top of boss is touched and is connected ball sealer (2), when controlling rod held up in external force, the middle part boss jack-up ball sealer of controlling rod made valve opening, when loosening, the controlling rod freedom falls along guide groove, loses holder power, the timely return of the pressure of ball sealer self gravitation and water, with the through hole sealing, valve just cuts out voluntarily.
Claims (1)
1. a self-closing water-saving valve is made up of valve body and spool, it is characterized in that valve body is vertical valve body (1), spool is ball sealer (2), ball sealer (2) is installed on valve body (1) and goes up in the aperture and with the segment shape shrinkage pool of valve body (1) to become to be connected movingly closely, the valve body (1) that is positioned at ball sealer (2) bottom is gone up the laterally slotting controlling rod (3) that is connected with, locating stud (4) is housed on the controlling rod (3), controlling rod (3) and valve body (1) are located by connecting, and the top of controlling rod (3) middle part boss touches ball sealer (2).
