Abstract

The utility model belongs to household goods, particularly an adjustable constant-pressure water limiting valve which can limit water by steps, adjust water output freely, and balance water current pressure automatically in order to save water. The adjustable constant-pressure water limiting valve mainly solves the problem that ordinary water taps are arbitrarily opened and closed, and waste much water in use. The adjustable constant-pressure water limiting valve is mainly composed of a stopper, a spring tab, a pressing spring, a connecting rod, a sealing member, a pull handle, a valve body, etc., wherein, the stopper, the spring tab, the pressing spring, a pull rod and the pull handle are connected into integration. The pull handle is pulled outside the valve body by the sealing member to release the stopper, and then the stopper is sprung back by the pressing spring to quantify water. The adjustable constant-pressure water limiting valve is mainly arranged at the back of ordinary water taps, or is used with the water taps to save water. With the advantages of small size, simple structure, convenient installation and use, and compulsory water saving property, the utility model is easy to be popularized in the urban and rural areas where the population is dense and water is lack in China.

Description

Adjustable constant-pressure water limiting valve

The utility model belongs to daily necessities, especially relate to a kind of can be matching used with ordinary faucet, restriction water-flowing amount, equal permanent water-outlet quantity, and the adjustable constant voltage that can adjust the water yield valve of restricting water supply.

Present widely used running water tap, switch is too random, and people are revolved one to two circle slightly, and water-outlet quantity just can not say that greatly the water that the water that people are used does not also flow away is many under a variety of situations, unfortunately tangible.This water tap for various users, is difficult to make them what all note using, and opens great principle, and therefore necessary consideration is to the restriction of the stepping of water discharge of water faucet.The possessor has worked out touch-type water tap and self-closing water tap to the greatest extent, but these products all lack randomness, convenience, the adjustability of ordinary faucet, therefore, still can't spread to civilian.

The purpose of this utility model, just be to propose a kind of energy and ordinary faucet matching used, the place that compensates its defect; Make water discharge of water faucet restricted, the stepping throttling, and can free adjustment, enlarge or reduce the valve of water-outlet quantity.

The purpose of this utility model is to realize like this, this valve is installed in the back of water tap, when water tap is opened, because the effect of this valve makes the water of outflow small and weak, the pull handle of pull-up valve, make with valve body that pull handle links to each other in jam decontrol, current are promptly unblocked, pull handle draws back big more, jam is decontroled big more, and water is just big more.Pull handle unclamps, and water is multiple little again, reaches the effect that stepping is regulated.Avoided people's undue randomness or be not intended to out big.Pressure owing to current increases with the reduction of the building number of plies again, so the pressure regulation reed is housed on jam, pressure is big more, just the water passage hole on the jam of spring compressing, so just limited the water yield that flows through to a certain extent from the jam hole, the water that water outlet comes out is just little.Otherwise floor is high more, and pressure is more little, and the reed displacement reduces, and the water that flows through the hole is just big slightly, and like this, pressure varies in size, and all can make water-outlet quantity approximate identical, plays water saving effect.

The utility model provides the following drawings:

The restrict water supply sectional drawing of valve of Fig. 1, adjustable constant voltage.

Fig. 2, jam upstream face schematic representation.

Wherein: (1) pull handle; (2) upper cover; (3) seal ring; (4) capping down; (5) stage clip; (6) pull bar; (7) pin; (8) jam; (9) spring sheet; (10) jam hole; (11) valve casing; (12) screw; (13) rivet;

Now in conjunction with the accompanying drawings, the utility model is described specifically.

As shown in Figure 1, the water tap that connects suitable for reading is internal thread; End opening connects on waterpipe, is outer screw thread.When water tap is opened, water enters from the lower end of valve body, and from outflow suitable for reading, at this moment, current stop by jam (8) basically, has only to flow out sub-fraction water flow out from water tap from jam hole (10).Jam (8) is the thin discs of several millimeters thick, is fixed on an end of pull bar (6) by primary screw (12).The other end of pull bar (6) is a square joint, inserts in the pull handle with cubic hole, and both are connected by a pin that passes wherein.The great circle hole of pull handle (1) taper is used for finger pull handle (1).When pull handle (1) is pulled up, jam (8) also with on move, the water route is decontroled.

Infiltration aperture (10) is arranged on the jam (8), also have a spring sheet (9), rivetted on jam (8) by the oblique shape of rivet (13), when water pressure was big, current compressing reed (9) was near jam hole (10), but unlikely being blocked makes it to hinder some flows; Water hour spring sheet (9) is motionless, and its position as shown in Figure 2.A recoil press spring (5) is arranged on connecting rod (6), and after pull bar (6) was drawn out, staff unclamped, and stage clip (5) compressing jam (8) makes its return.

Lower sealing cover (4) is connected with silking with valve body (11), the outside is a hexagon nut shape, seal ring (3) is between top cover labyrinth (2) and lower seal (3), compressed with being threaded by the upper-lower seal lid, play seal action, top cover labyrinth (2) outside also is a hexagon nut shape, is convenient to install.Pull bar (6) passes upper-lower seal lid and seal ring (3), for slip is passed.

This valve can have a style of one's own, also can be when producing and water tap close and be made as one.

The utility model volume is little, and is simple in structure, and processing ease is easy to use; Stepping is restricted water supply, and forces water-saving result good, the effect of also not losing ordinary faucet. Particularly suitable in water-deficient area, China town and country, be a kind of good water limiting valve.

Claims (2)

1, a kind of adjustable constant voltage valve of restricting water supply is characterized in that; One termination water supply pipe, one termination water tap, with the supporting use of water tap, be provided with a kind of plug of restricting water supply (8) in its valve body, water limited pore (10) is arranged on the plug (8), a spring sheet (9) is arranged on plug (8), by rivet (13) be oblique shape fixing above, this plug (8) is fastened on the connecting rod (6) by screw (12), connecting rod (6) is connected as one with pin (7) and pull handle (1), connecting rod (6) is the slip shape and passes top cover labyrinth (2), lower sealing cover (4) and seal ring (3), and plug (8) can be pulled up or put down by connecting rod (6) and pull handle (1).

2, according to the described valve of claim 1, it is characterized in that; This valve can have a style of one's own and the supporting use of ordinary tap water tap, also can be when producing and ordinary faucet close and be made as one.
