Abstract
The invention relates to a water drainage device of a fire hydrant. The fire hydrant is provided with a hollow cylinder body; a water outlet interface connected with an external water hose is formed at the upper part of the cylinder body; the lower part of the cylinder body is communicated with an underground water supply pipe; and a valve body used for controlling the connection between the cylinder body and a water inlet interface is arranged at the communicated portion; a water outlet is formed on the side wall of the cylinder body; and the water outlet is formed on the side wall of the lower part of the cylinder body. By using the fire hydrant provided by the invention, the water accumulated in the cylinder body can be effectively drained in time through the water outlet so that unsmooth water outlet, even blockage, caused by rusting or icing, is effectively prevented.
Description
Technical field
The present invention relates to a kind of dewatering installation of hydrant.
Background technology
Generally, the cylindrical shell of hydrant is set to hollow usually, and the water outlet interface is offered on the top of cylindrical shell, and the bottom of cylindrical shell is connected with underground water inlet interface, and connection place is provided with the open and close of valve body control cylindrical shell and water inlet interface.When putting out a fire, current spray from the water outlet interface through hollow cylindrical shell.But often after using, have ponding and stay in the hollow cylindrical shell, and the time has been grown and is easy to cause barrel, particularly getting rusty appears in the bottom of cylindrical shell; When wintry weather was cold, the ponding in the cylindrical shell froze easily, when the needs water outlet, because barrel is stopped up, caused water outlet smooth even can't water outlet easily.
Summary of the invention
The present invention provides a kind of dewatering installation of hydrant.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of dewatering installation of hydrant; Described hydrant has a hollow cylindrical shell; The top of described cylindrical shell offers and is used for the water outlet interface that is connected with the external water band, and the bottom of described cylindrical shell is connected with the groundwater supply pipe, and described barrel is provided with to be used to limit described water outlet interface water outlet whether valve body; Offer delivery port on the described cylinder lateral wall, described delivery port is opened on the sidewall of described cylindrical shell bottom.
Preferably, described delivery port is connected with an outlet bend pipe.
Further preferably, the bending angle of described outlet bend pipe is 90 degree.
Because the technique scheme utilization, the present invention compared with prior art has advantage: hydrant of the present invention can effectively in time be discharged the ponding in the cylindrical shell through delivery port, effectively having prevented to get rusty or the icing smooth or even obstruction that causes water outlet.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is an A portion enlarged drawing in the accompanying drawing 1.
Wherein: 1, cylindrical shell; 2, cavity; 3, water outlet interface; 4, inlet channel; 5, valve body; 6, delivery port; 7, outlet bend pipe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
A kind of hydrant as shown in Figure 1; This hydrant has the cylindrical shell 1 that a set inside has cavity 2; The top of cylindrical shell 1 offers and is used for the water outlet interface 3 that is connected with the external water band; The bottom of cylindrical shell 1 is connected with the inlet channel 4 that is connected with the groundwater supply pipe, and cylindrical shell 1 set inside is useful on qualification water outlet interface 3 water outlets whether valve body.When hydrant needs water outlet, open valve body 5, water is drawn from water outlet interface 3 through the cavity 2 of cylindrical shell 1 from inlet channel 4.
In addition, because the bending design of outlet bend pipe 7, when opening valve body 5 and carry out water outlet, underground hydraulic pressure is bigger, water base only ejection from water outlet interface 3; And after the valve body 5, hydraulic pressure disappears, and the delivery port 6 from than low level of water nature is got rid of.Like this, need not can realize automatic draining through control.
Can certainly not connect outlet bend pipe 7, the device of its open and close of control is set at delivery port 6 places, also can serve the same role.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (3)
