Description
Technical field
The utility model belongs to a kind of anti-backflow device of metro using mining tunnel drainage.
Background technology
In city underground rail tunnel and mining tunnel operation are built, the construction of pumping equipment is the entire network of communication lines
The basis of network system running.Substantially all traditional tunnel drainage is all to access sedimentation basin by the steel pipe of a diameter of 180mm, is led to
It is imported in city planting ductwork after crossing precipitation, when being drained by steel pipe, when water pump closes power supply, it will usually water in pipe be caused to return
The phenomenon that flowing, be easy to causeing underground pipe network recharge occurs, and the water of recharge affects the operation of underground rail and mining tunnel, causes
Unnecessary property expenditure and waste.
Invention content
The purpose of this utility model is a kind of anti-backflow device of metro using mining tunnel drainage of design, and the certainly draining recharge that can shut out is existing
The generation of elephant has simple in structure, safe and reliable, the advantages of installation speed is fast, convenient maintenance and replacement.
For this reason, the utility model is made of drainpipe and water pump, non-return is equipped in the drainpipe on the outside of pump outlet
Valve.The check-valves is constituted by fixing lifting lug, valve plate, valve plate engaging lug and limited post.Draining on the outside of pump outlet
Upper end is equipped with fixed lifting lug in pipe, and the valve plate end face at corresponding fixed lifting lug position is equipped with valve plate engaging lug, and valve plate engaging lug is logical
Axis is crossed to connect with fixed shackle shaft.It is equipped with limited post in the drainpipe of valve plate end face lower end on the outside of corresponding pump outlet.
The check-valves is：Jack-post is located on the drainpipe cross-sectional diameter on the outside of pump outlet, two be in semicircle
The straight flange of the valve plate of type connects with jack-post axis.It is equipped with limit in the drainpipe of two valve plate end faces on the outside of corresponding pump outlet
Column.Connection ring is set in the middle part of two valve plate end faces on the outside of corresponding pump outlet, tension spring is set between two connection rings.The row
One end of water pipe is communicated with pump outlet, and the other end communicates ground sedimentation basin.
Said structure design has reached the purpose of this utility model.
The utility model, which can shut out, certainly drains the generation of recharge phenomenon, has simple in structure, safe and reliable, installation speed
The advantages of degree is fast, convenient maintenance and replacement.
Description of the drawings
Fig. 1 is the using state structure diagram of the utility model.
Fig. 2 is the structural schematic diagram of another embodiment of the utility model.
Specific implementation mode
Embodiment 1, as shown in Figure 1, a kind of anti-backflow device of metro using mining tunnel drainage is by 4 groups of drainpipe 6 and water pump
At.Check-valves is equipped in drainpipe on the outside of pump outlet.The check-valves is connected by fixing lifting lug 2, valve plate 3, valve plate
Ear 5 and limited post 7 are constituted.Upper end is equipped with fixed lifting lug, corresponding fixed lifting lug position in drainpipe on the outside of pump outlet
Valve plate end face be equipped with valve plate engaging lug, valve plate engaging lug by axis 1 with fixation shackle shaft connect.On the outside of corresponding pump outlet
Valve plate end face lower end drainpipe in be equipped with limited post.
When draining, the ponding in metro using mining tunnel is pumped into from pump intake and enters row from pump outlet by water pump
In water pipe, valve plate is washed open by pressure outward into the ponding in drainpipe, i.e. valve plate is outside around axis by valve plate engaging lug
Side is unfolded, and is opened drainpipe, is entered in the sedimentation basin of ground into the ponding in drainpipe, and ponding is by importing municipal administration pipe after precipitation
In net.After water pump is closed, valve plate loses the pressure of pump pressure water, and the pressure of recharge water in drainpipe is coordinated to fall inwardly, closes
Drainpipe is closed, limited post and axis hold the valve plate both ends of the surface of closing jointly.It can effectively prevent the generation of draining recharge phenomenon.
Embodiment 2, as shown in Fig. 2, the drainpipe on the outside of pump outlet is interior equipped with check-valves.The check-valves is：
Jack-post 8 is located on the drainpipe cross-sectional diameter on the outside of pump outlet.Two straight flanges and axis in semi-circular valve plate 10,12
Axis of a cylinder connects.It is equipped with limited post 7 in the drainpipe of two valve plate end faces on the outside of corresponding pump outlet.Outside corresponding pump outlet
Connection ring 9 is set in the middle part of two valve plate end faces of side, tension spring 11 is set between two connection rings.One end of the drainpipe and water pump
Water outlet communicates, and the other end communicates ground sedimentation basin.
When draining, the ponding in metro using mining tunnel is pumped into from pump intake and enters row from pump outlet by water pump
In water pipe, two semi-circular valve plates, i.e. two semi-circular valves are washed open outward by pressure into the ponding in drainpipe
Plate is around axially external merging, while tension spring is unfolded, and drainpipe is opened, and ponding enters in the sedimentation basin of ground, after ponding is by precipitation
It imports in city planting ductwork.After water pump is closed, two semi-circular valve plates lose the pressure of pump pressure water, and two semi-circular valve plates exist
The pulling force of tension spring simultaneously coordinates the pressure of recharge water in drainpipe to be unfolded around axially inner side, closes drainpipe, limited post and axis are common
Hold two semi-circular valve plate both ends of the surface of closing.It can effectively prevent the generation of draining recharge phenomenon.
The utility model, which can shut out, certainly drains the generation of recharge phenomenon, has simple in structure, safe and reliable, installation speed
The advantages of degree is fast, convenient maintenance and replacement.
