Abstract

The utility model discloses a floating valve time-delay self-closing water tap, belonging to a daily domestic water facility. One side of a valve body of the utility model is provided with a water inlet, and the other side is provided with a water outlet. The lower part of the valve body is provided with an operating handle on which a magnetic steel is arranged. The upper part of a big valve mouth in the valve body is provided with a floating valve. A gap is reserved between the periphery of the floating valve and the valve body. The center of the floating valve is provided with a small valve mouth. A guiding valve penetrates through the small valve mouth. The lower end of the guiding valve is provided with a magnetic steel. The utility model has the advantages of reasonable structure, high sensitivity, reliable operation and low requirement for water quality. The utility model is not easily blocked. The utility model can be used for not only a high water pressure source but also a low water pressure source.

Description

Floating valve formula delay-self-closing water tap

The utility model relates to a kind of floating valve formula delay-self-closing water tap, belongs to the daily life drainage facility.

Present delay-self-closing water tap generally has piston type and diaphragm type, and they are to move to promote piston and diaphragm by a small pore water-filling, realize discharging water and delay-self-closing.Stop up easily during the small pore of this series products uses and lost efficacy, thus to requirements in water quality than higher, in addition, its hermetic resistance is bigger, use can not fine work under the occasion of low hydraulic pressure source.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of floating valve formula delay-self-closing water tap is provided, and its floating valve can freely fluctuate in valve body, and resistance is little, and is highly sensitive, is difficult for stopping up, and reliable operation is applicable to the high and low pressure water source.

The purpose of this utility model is achieved in that it comprises valve body, water intake, water outlet, operating grip, and valve body one side is established water intake, and opposite side sets out the mouth of a river, and below fitting operation handle is equipped with magnet steel on the operating grip; Floating valve is installed in big valve port top in the valve body, leaves the gap between the periphery of floating valve and valve body, and the center is provided with little valve port, is coated with pilot valve in the little valve port, and the lower end of pilot valve is equipped with magnet steel.

Compared with prior art, advantage of the present utility model is owing to adopted floating valve, and leaves the gap between floating valve and valve body, can freely fluctuate in valve body, resistance is little, and is highly sensitive, be difficult for stopping up, reliable operation, therefore, structure is more reasonable, using scope is wide, low to water quality requirement, not only can be used for high hydraulic pressure source, be more suitable under the occasion of low hydraulic pressure source, working.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of the utility model water outlet below valve body

Fig. 3 is the inverted structural representation of the utility model valve body.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Valve body 1 one sides of the present utility model are established water intake 7, and opposite side sets out the mouth of a river 13, and below fitting operation handle 12 is equipped with magnet steel 9 on the operating grip 12; Floating valve 2 is installed in big valve port 5 tops in the

valve body

1, and 1 of the periphery of floating valve 2 and valve body leave gap 6, and the center is provided with little valve port 11, is coated with pilot valve 3 in the little valve port 11, and the lower end of pilot valve 3 is equipped with magnet steel 10.

The utility model can also realize that promptly its water outlet 13 can also be provided in a side of the below of valve body 1 by following measure, and trustship 14 is installed in it, and the upper end of trustship 14 is connected with the lower end of pilot valve 3.Its valve body 1 can also be to be inverted, install and fix cover 18 on the valve body 1, the fixed cover 18 outer glands 16 that are set with, gland 16 centers are provided with pressure head 15, pressure head 15 is inserted in the fixed cover 18, seal ring 19 is installed on it, and its lower end contacts with the termination of pilot valve 3, and 16 of fixed cover 18 and glands are equipped with stage clip 17.

When floating valve 2 and pilot valve 3 all are in when the next, big valve port 5 and little valve port 11 are closed, and have cut off the path of water intake 7 and water outlet 13, and at this moment, the utility model is a closed condition.At this moment, the water in the following water cavity 8 has entered by gap 6 and has been full of upper water cavity 4, and the hydraulic pressure of following water cavity 8 and upper water cavity 4 equates, is water source hydraulic pressure.Floating valve 2 belows then are atmospheric pressure, and it is less than water source hydraulic pressure, and this pressure difference is the power of closing of floating valve 2.During use, upwards move operating grip 12, by two blocks of magnet steel 9 and 10 repulsive interaction mutually, jack-up pilot valve 3 makes progress, or upwards hold up trustship 14, direct jack-up pilot valve 3 upwards, or press down gland 16, depress pilot valve 3 by pressure head 15, open little valve port 11, at this moment, the instant water in the upper water cavity 4 flows out from little valve port 11, causes the pressure difference of upper water cavity 4 and following water cavity 8, floating valve 2 floats, valve port 5 is open greatly, and water directly from water cavity 8, big valve port 5, water outlet 13 outflows down of water intake 7 warps, is the state of discharging water of opening.The operation action that discharges water was finished in moment, and therefore, return immediately after pilot valve 3 is opened is closed little valve port 11, at this moment, water flows out from big valve port 5 on the one hand, 6 charges into upper water cavity 4 from the gap on the other hand, forces floating valve 2 return gradually, until closing big valve port 5, block the water source, stop to discharge water.This process is the delay-self-closing process.Stage clip 17 can make gland 16 upspring, and seal ring 19 can prevent to leak, and delay time can be controlled in 4-10 about second.The utility model low hydraulic pressure source occasions such as cabinet that are specially adapted to wash one's face as passenger train.
