Abstract
The utility model relates to an automatic switch valve for a fire hydrant. A water outlet chamber is arranged inside a valve body, and the upper part of the water outlet chamber is provided with a hole. A water inlet chamber is formed at the outer part of the water outlet chamber inside the valve body. A rubber sealing bowl is arranged on the hole at the upper part of the water outlet chamber. The edge of the rubber sealing bowl is fixed on the valve body by a valve cap. A water feeding chamber is formed by the rubber sealing bowl and the valve cap. The side wall of the rubber sealing bowl is provided with a water guide hole. The water feeding chamber and the water outlet chamber are communicated by a pipe passage. The pipe passage is arranged at the outer part of the valve body. A control valve is arranged on the pipe passage. When the utility model is used, the control valve 8 can be automatically opened, fire water supply can be automatically ejected from a water hose, and the time can be saved.
Description
The utility model relates to a kind of fire-fighting equipment, is meant a kind of fire hydrant automatic open and close valve especially.
At present, usually the fire hydrant that is used for fire fighting supply that adopts all is the fully manual valve of control, is characterized in: start and close slowly, and open and close all to have manually and finish, if wrong meeting generation running water phenomenon.
The purpose of this utility model just provides a kind of fire hydrant automatic open and close valve of energy automatic on-off.
The purpose of this utility model is achieved in that a kind of fire hydrant automatic open and close valve, by valve gap, valve body is formed, in valve body, be provided with water-supplying chamber, water-supplying chamber's top perforate, the outside intake chamber that forms of water-supplying chamber in valve body, the rubber seal bowl is arranged on the hole on water-supplying chamber top, the rubber seal bowl is a matrix, the edge of rubber seal bowl is fixed on the valve body by valve gap, rubber seal bowl and valve gap form upper tank, the sidewall of rubber seal bowl has water-guiding hole, and the center of rubber seal bowl has the hole, and the boss of flap tightly is enclosed within the hole of rubber seal bowl, the lining bowl places in the rubber seal bowl, and be enclosed within on the boss of flap, one section of spring is fixed on the valve gap, and the other end is fixed on the boss of flap; At upper tank and water-supplying chamber's pipeline connection, pipeline is arranged on the outside of valve body, and its pipeline is provided with control valve.In the hole on water-supplying chamber top, be provided with copper sheathing.
When fire alarm took place, this fire hydrant automatic open and close valve can be opened the fire hydrant water route fast and automatically, and saves time.
Fig. 1 is the utility model structural representation.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the fire hydrant automatic open and close valve is by valve gap 1, valve body 7 is formed, in valve body 7, be provided with water-supplying chamber 11, water-supplying chamber 11 is connected with the water band, water-supplying chamber's 11 top perforates, in the hole on water-supplying chamber 11 tops, be provided with copper sheathing 5, water-supplying chamber's 11 outside intake chambers 14 that form in valve body 7, intake chamber 14 is connected with fire-prevention pipe by water intake, rubber seal bowl 4 is arranged on the hole on water-supplying chamber 11 tops, rubber seal bowl 4 is separated water-supplying chamber 11 with intake chamber 14, rubber seal bowl 4 is a matrix, like this, the bottom of rubber seal bowl 4 can move up and down, the edge of rubber seal bowl 4 is fixed on the valve body 7 by valve gap 1, rubber seal bowl 4 forms upper tank 10 with valve gap 1, the sidewall of rubber seal bowl 4 has water-guiding hole 15, water-guiding hole 15 makes upper tank 10 be communicated with intake chamber 14, the center of rubber seal bowl 4 has the hole, the boss of flap 6 tightly is enclosed within the hole of rubber seal bowl 4, and lining bowl 3 places in the rubber seal bowl 4, and is enclosed within on the boss of flap 6, one end of spring 2 is fixed on the valve gap 1, and the other end is fixed on the boss of flap 6; Be communicated with water-supplying chamber 11 usefulness pipelines 9 at upper tank 10, pipeline 9 is arranged on the outside of valve body 7, and its pipeline 9 is provided with control valve 8.
When fire alarm takes place when, control valve 8 on the pipeline 9 is opened, water in the upper tank 10 is flowed in the water-supplying chamber 11, like this, hydraulic pressure in the upper tank 10 reduces, and the hydraulic pressure of intake chamber 14 is greater than the pressure in the upper tank 10, and rubber seal bowl 4 is pushed to the top by the pressure of intake chamber 14 and moved, the water of intake chamber 14 is gone in the water-supplying chamber 11 from the orifice flow on water-supplying chamber 11 tops, thereby flow in the water band.When after hours, control valve 8 to be closed, the water of intake chamber 14 flows in the upper tank 10 from the water-guiding hole 15 on the rubber seal bowl 4, make the pressure in the upper tank 10 identical with the pressure of intake chamber 14, under the effect of spring 2, rubber seal bowl 4 moves down, with the hole sealing on water-supplying chamber 11 tops.
