Description
The utility model belongs to a kind of pipeline water valve from the beginning, and pattern is normally closed, opens the back delay-self-closing, is particularly suitable for doing the flushing valve and the public place water valve from the beginning of large and small closet tool.
China Patent No. is that 8929848 Chinese patent has been introduced a kind of delay-self-closing flushing valve, mainly form by core-skin valve seat and flushing spool two large divisions, time-lag action is realized by water as medium, its subject matter is: delay time length can not be adjusted according to the hydraulic pressure that uses the place and the needs of use, when hydraulic pressure Pg<0.05MPa, valve be prone to open ineffective, close dead phenomenon; The spool water inlet is easily stopped up by impurity in the water, makes the valve can't switch.
The purpose of this utility model is to provide a kind of delay time and to use needs adjustable according to the hydraulic pressure situation, can be in the water supply pipe proper functioning of work water pressure Pg<1.6MPa, and applicability is good, reliable operation, delay-self-closing water valve rational in infrastructure.
The utility model adopts the medium of air as time-delay control, and by the length that the intake velocity of regulating air chamber is regulated delay time, it is made up of valve seat, spool two large divisions.Valve seat comprises valve body, plug screw, seal ring, and water-inlet cavity and water chamber are arranged on the valve body, and two chambeies are communicated with by its shaft axis and water intake, the mistake mouth of a river that the water outlet shaft axis is vertical.Spool divides control section and fixing seal part, the fixing seal part is made up of cartridge cover and seal ring, control section comprises button, push rod, the valve that constitutes by valve block and rubber pad, and be placed on the push rod and be loaded on the cartridge cover air chamber base and the rubber membrane that constitutes air chamber, valve is arranged on the influent side in the valve body, and push rod is threaded with button.Realize that the technical solution of the utility model is the rubber spring that sealed air chamber and throttle down double action have been housed between air chamber base and push rod, push rod has sealed step to contact with the rubber membrane internal surface, push rod is provided with the inlet hole that communicates with air chamber, button is provided with the turnover gas breach of linking up atmosphere and inlet hole, be provided with the intake velocity control mechanism at air inlet position, thereby realize the adjustable self-closing purpose of time-delay.Concrete structure of the present utility model is described with reference to the accompanying drawings as follows:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the utility model is made up of valve seat, spool two large divisions, valve seat is made up of valve body (7), plug screw (13), seal ring (17), and valve body (7) divides water-inlet cavity and water chamber, and two chambeies are communicated with by its shaft axis and water intake, the mistake mouth of a river that the water outlet shaft axis is vertical.Described spool divides control and fixing seal two-part, and the fixing seal part is made up of cartridge cover (4) and seal ring (16), cartridge cover (4) and valve body (7) scyewed joint.The valve that control section comprises button (1), push rod (6), is made of valve block (10) and rubber pad (9), and be placed in push rod (6) and go up and be loaded on cartridge cover (4) and go up air chamber base (5) and the rubber membrane (3) that constitutes air chamber.Valve is arranged on the influent side in the valve body (7), and push rod (6) is threaded with button (1).Outstanding feature of the present utility model is between air chamber base (5) and the push rod (6) rubber spring (8) to be housed, it plays the double action of sealed air chamber and throttle down, has a step to contact (say from its function and can be referred to as sealed step) with rubber membrane (3) internal surface on the push rod (6).Push rod (6) is provided with the inlet hole (14) that communicates with air chamber, button (1) is provided with the turnover gas breach (15) of linking up atmosphere and inlet hole (14), locate to be provided with the mechanism of control intake velocity at inlet hole (14), Fig. 1 has provided an embodiment, a control gas coning shape screw (2) promptly is set in the interior threaded hole of button (1), top at button (1) has aperture, and screw (2) tapering part stretches into the length of inlet hole (14) and can adjust by this hole.Another outstanding feature of the present utility model is that valve can be the combined type valve of being made up of large and small valve.Promptly there is water passage hole in the central authorities at aforementioned valve block (10) and seal ring (9), make this water passage hole normally closed by one with the cone-head screw (12) of push rod (6) scyewed joint and seal ring (11) sealing, cone-head screw (12), seal ring (11) formation minor valve.Adopt this structure, should have one crack t is installed between rubber pad (9) and the push rod (6).
Working principle of the present utility model is as follows:
When this valve remained static, rubber spring (8) was strained push rod (6), valve closing, and water is blocked, and can not flow out valve body (7).The lower end surface that push rod (6) is installed rubber spring (8) has the spilling water breach, between push rod (6) and the rubber pad (9) clearance t is arranged, press the button (1) with hand, opened earlier by the minor valve that screw (12) and rubber ring (11) are formed, water is from the gap between valve block (10) and the minor valve, and the breach through push rod (6) lower end flows out, button continues to press down, push rod (6) contacts with rubber pad (9), big valve opening, and water flows out valve body (7).Owing between button (1) and the rubber membrane (3) gap is arranged, during button pressed downwards, the step surface that push rod (6) engages with rubber membrane (3) inner face leaves rubber membrane (3) and forms a gap, and the turnover gas breach (15) of air on this gap and button (1) below the rubber membrane discharged rapidly; When the openhanded button (1) of opening, push rod (6) is risen by the pulling force of rubber spring (8), the air chamber sealing that the step surface that push rod (6) engages with rubber membrane (3) constitutes rubber membrane (3) and air chamber base (5), rarefaction of air in the air chamber, barometric pressure above the rubber membrane (3) stops rubber membrane (3) to rise, and rubber membrane (3) stops push rod (6) that valve can not be closed immediately.The inlet hole (14) that communicates with air chamber is arranged on the push rod (6), all gapped between the upper-end surface of control gas screw (2) and push rod (6) and the inlet hole (14).The turnover gas breach (15) of air from the button (1) through the gap, inlet hole (14) enters air chamber.The air of air chamber increases gradually, and rubber membrane rises gradually, and push rod also rises gradually, at last with valve closing.Small screw driver, insertion button (1) top aperture can be adjusted the lifting of controlling gas screw (2), just adjust the speed that air enters air chamber, delay time obtains adjusting.
The utlity model has following advantage: 1. delay time is adjustable and easy to adjust, has stronger practicality; 2. valve is the combination valve that is made up of large and small valve, flexible operation, and can increase service life; 3. adopt the rubber spring valve-off, reliable operation, action is mild; 4. overall structure advantages of simple, handling ease, interchangeability is good.
