Abstract

The utility model discloses a time-delay and adjustable tap. The existing water tap comprises a hand press valve, a laser-type water tap, etc; the hand press valve can drain by depressing the handle; the characteristic of the hand press valve can save water, but washing hands inconveniently; the laser-type water tap has the characteristics of water saving and easy use, but the cost is high. The utility model is the improved product of the hand press valve; a check valve, a flow regulating valve, and a pressing spiral plate; a taper sleeve is arranged in the liner, an air chamber is arranged in the valve body, the input of the air can be changed by wringing the cock, and the goal of time-delay, adjustment, and water saving is achieved. The water saving tap applies to the public places and washrooms.

Description

Time-delay and adjustable tap

The utility model relates to a kind of time-delay can regulate water tap that is used for public place and Rest Room.

The water tap of prior art has hand press valve, laser type water tap, time-delay water-saving valve etc.Hand press valve, depress handle after, valve opening, after loosing one's grip, spring jack-up valve core reset, valve closing, this hand press valve water-saving result is better, but in use, and is just inconvenient when particularly washing one's hands.Characteristics such as that the laser type water tap has is easy to use, water saving, but cost is higher, thereby using scope is restricted.The time-delay water-saving valve that utilizes fluid pressure differential to produce " water tank effect " has characteristics such as unlatching is laborsaving, water saving, health, but the discharge time of this water-saving valve is determined by not isometric " water tank effect ", so, compressing time is long, " water tank effect " just corresponding increase, the corresponding prolongation of discharge time.

The purpose of this utility model is the characteristics according to above-mentioned water tap, maximize favourable factors and minimize unfavourable ones, for society provide a kind of can using water wisely, easy to use, time-delay can regulate water tap that cost is lower.

Solution is: hand press valve is improved, an one-way valve, a throttle valve and a pressed screw plate are installed on valve body, with the bottom of spring contact pressed screw plate and spool, the bottom of pressed screw plate, lining and spool constitutes an air chamber, designs a tapered sleeve and is engaged in the lining.

Water conserving tap cost of the present utility model is lower, easy processing and fabricating, and the user can turn the cock of throttle valve as required, reaches the purpose of the adjustable water saving of time-delay.

Accompanying drawing is a structural representation of the present utility model.Water conserving tap has handle (1), lining (2), spool (3), valve body members such as (5).

Description of drawings an embodiment of the present utility model: an one-way valve (7), a throttle valve (8) and a pressed screw plate (9) are arranged on valve body (5), one end of spring (6) contacts with pressed screw plate (9), the following end in contact of the other end and spool (3), the bottom of lining (2), pressed screw plate (9) and spool (3) constitutes an air chamber (10), and tapered sleeve (4) is engaged in the lining (2).Press lower handle (1) with hand, spool (3) descends, water conserving tap begins to discharge water, spring (6) is compressed, air in the air chamber (10) is compressed, pressurized air is opened one-way valve (7), air in the air chamber (10) is discharged through one-way valve (7), and one-way valve can stop air to enter air chamber (10), when hand leaves handle (1), spring (6) jack-up spool (3) resets, negative pressure appears in the air in the air chamber (10), stops spool (3) to reset, and air enters air chamber (10) through throttle valve (8), after spool (3) resetted, water conserving tap stopped to discharge water.The size of air inlet amount can determine the speed that spool (3) resets, and turns the cock (11) of throttle valve (8), can change the air inflow of air, reaches can the delay time purpose of adjustable water saving of water conserving tap.

Claims

1, a kind of time-delay can regulate water tap, have members such as handle, lining, spool, valve body, feature of the present utility model is that one-way valve [7], throttle valve [8] and pressed screw plate [9] are arranged on the valve body [5], one end of spring [6] contacts with pressed screw plate [9], the other end contacts with spool [3], the bottom of lining [2], pressed screw plate [9] and spool [3] constitutes an air chamber [10], and tapered sleeve [4] is engaged in the lining [2].

2, water tap according to claim 1 is characterized in that one-way valve (7) closes always, in case the air pressurized in the air chamber (10), one-way valve (7) is just opened.
