Abstract

The utility model relates to a device which is used for the water saving of a water pipe and the water-seal of a water pipe. A valve body is provided with a hollow tubular structure, the top end is a water entry end, and the other end is an outlet end. A valve handle is inserted into a through hole of the valve body, a water-seal cap on the upper can be closely contacted with the water entry end surface of the valve body, a push plate is arranged at the lower part of the device, and the valve handle can up-and-down slide in the through hole of the valve body. The device is characterized in that three longitudinal aqueduct baths are processed on a cylinder of the valve handle, and the fan-shaped included angle of every aqueduct bath and a middle axle of the cylinder of the valve handle is 120 DEG. Compared with the existing product, the utility model has the advantages of simple structure, easy use, low cost and high water saving efficient.

Description

A kind of sealing valve

The utility model is a kind of water saving, water cut-off device that is used on the water pipe, and it relates to the raising on structural improvement of existing product and the performance, belongs to the manufacturing technical field.

Water tap in using at present is normally direct-connected with water pipe, in the process of user's water, is different to the demand of the water yield in different operational phases.Behind the tap of fetching boiling water, the user generally seldom can regulate the switch of water tap according to the size of institute's water requirement at that time.Because water tap is after opening, its water-outlet quantity is generally all bigger, in most cases all greater than use at that time needs all, like this, in making the process of water, has just caused waste to a certain extent.The long-time loss that is caused is just very surprising.In addition, when changing water tap, in the time can't closing total sluice gate, the water that the replacing process is wasted also is very big.The water resources anxiety now, these can cause the phenomenon of wasting water just to become the problem that current urgent need will solve.

The purpose of this utility model designs water saving, the water cut-off device on the water pipe of being used for that a kind of new structure is provided just at the existing problem of above-mentioned situation, it can keep mild current when using at ordinary times, to reach the effect of water saving, and when changing water tap, this device can block current automatically, makes this process not have the loss of water.

The purpose of this utility model realizes by following measure:

This kind sealing valve, its valve body is a hollow tubular structure, its top is a water intake end, and the other end is the waterexit end, wears a valve rod in the through hole of valve body, its top sealing cap can with airtight contact of entry end face of valve body, a pushing tow dish is installed in its underpart, and this valve rod can slide up and down in the through hole of valve body, and its structure characteristic is, be processed with three water delivery grooves longitudinally on the cylindrical body of valve rod, each water delivery groove is 120 degree with respect to the fan-shaped angle of the axis of cylindrical body valve rod.In use, the water intake end of valve body is connected with water pipe, under the effect of hydraulic pressure, the sealing cap of valve body inner valve stem is pressed on the entry end face in water pipe, stops passing through of water.When changing water tap, will cause this situation.When water tap was installed, the incoming end that water tap is connected with valve body can promote the pushing tow dish of stem lower portion forward, and sealing cap and entry end face are separated, and current will flow out downwards along the water delivery groove of valve rod.Because the effect of water delivery groove, current can become gently, to reach the purpose of water saving.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the overall structure schematic representation of the utility model device

Fig. 2 is the worm's eye view of valve rod in the utility model device

Fig. 3 is the structural representation of pushing tow dish in the utility model device

Below with reference to drawings and Examples the utility model is further described:

Shown in accompanying drawing 1-3,

This kind sealing valve, its valve body 2 is a hollow tubular structure, its top is a water intake end 1, the other end is waterexit end 5, in the through hole of valve body 2, wear a valve rod 6, its top sealing cap 10 can with 1 airtight contact of water intake end of valve body 2, its underpart is installed and is connected with the mounting hole 11 that a pushing tow dish 8 is by installation shaft 9, this valve rod 6 can slide up and down in the through hole of valve body 2, its structural design features is, be processed with three water delivery grooves 7 longitudinally on the cylindrical body of valve rod 6, each water delivery groove 7 is 120 degree with respect to the fan-shaped angle of the axis of cylindrical body valve rod 6.In order to guarantee that current are unobstructed, on pushing tow dish 8, also be processed with tank 12, consistent on its shape and position and the valve rod 6 also can be processed water passage hole therein.Owing to connect the relation of water pipe and water tap, the upper diameter of the through hole in the valve body 2 in the utility model device is less than its underpart diameter, on the outer surface on top, be processed with outside thread 3 and be connected, on the internal surface of bottom, be processed with internal thread 4 and be connected with water tap with water pipe.

In use, the water intake end 1 of valve body is connected with water pipe, in water pipe under the effect of hydraulic pressure, the sealing cap 10 of valve body inner valve stem is pressed on 1 of the water intake end, stops passing through of water.When changing water tap, will cause this situation.When water tap was installed, the incoming end that water tap is connected with valve body can promote the pushing tow dish 8 of stem lower portion forward, and 1 of sealing cap 10 and water intake end are separated, and current will flow out downwards along the water delivery groove 7 of valve rod.Because the effect of water delivery groove, current can become gently, to reach the purpose of water saving.

The utility model is compared with existing product to have simple in structurely, easy to use, and cost is low And the advantage that water saving efficiency is high.
