Abstract
The utility model provides a water-draining valve for a flood gate of an underground tunnel. The water-draining valve is arranged in a foundation of the flood gate of the underground tunnel and comprises a water-draining tube and a center shaft, wherein a support is fixedly arranged inside the water-draining tube; a bonnet is arranged at the front end of the water-draining tube; the front end of the center shaft penetrates through the middle of the bonnet and is fastened in the middle of the bonnet; the rear end of the center shaft penetrates through the support; a spring is sleeved on the center shaft and is pressed between the bonnet and the support; a limiting piece which is matched with the support is arranged at the rear end of the center shaft; a sealing gasket is arranged on the side surface, which faces the water-draining tube, of the bonnet; and an end cap is arranged at the rear end of the water-draining tube. The water-draining valve effectively prevents harm caused by interference of water when the water flows in the underground tunnel, and can automatically drain the water, so that safety operation of a system of the underground tunnel is guaranteed.
Description
Technical field
The utility model relates to a kind of drain valve, relates in particular to a kind of drain valve for the subterranean tunnel draining.
Background technique
Valve is the controlling component in the fluid delivery system, has cut-off, regulates, prevents the functions such as adverse current or overflow pressure relief.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) all various valves, its kind and specification are quite various.As shown in Figure 1; in subterranean tunnel; the anti-door that floods can be installed usually prevent some disasters; in the anti-bottom of flooding a 1A basic 2A is housed, in basic 2A, is provided with a pipeline 3A and carries out draining, and when water is larger; can't in time water all be discharged; therefore this situation can have a strong impact on the safe operation of the railway system, according to the characteristics of the security requirement of underground tunnel system, the drainage problem in the underground tunnel is had higher requirement.
Summary of the invention
The utility model provides a kind of drain valve for the deficiencies in the prior art, is subject to the harm that the interference of water causes when effectively having prevented from meeting water in the subterranean tunnel, played the effect of draining.
Of the present utility model for the anti-drain valve that floods door of subterranean tunnel, described drain valve is installed on subterranean tunnel and prevents flooding in the basis of door, it comprises a drain pipe, the inside of described drain pipe is installed with a support, the front end of described drain pipe is provided with a valve gap, described drain valve also comprises an axis, the front end of described axis runs through the middle part that is anchored on described valve gap, described support is run through in the rear end of described axis, one spring housing is located on the described axis and is installed with between described valve gap and described support, cooperates described support to be provided with a bounding means in the end, rear end of axis.
Described valve gap is provided with a sealing gasket over against described drain pipe side.
The rear end of described drain pipe is provided with an end cap.
Valve gap all is in opening state at ordinary times, current are discharged through drain pipe, when the depth of water of upstream face reaches 2 meters, hydraulic pressure surpasses the pressure maximum that spring can bear, hydraulic pressure just promotes valve gap, the effect of the sealing gasket of valve gap on the drain pipe side makes its Compress Spring until valve gap is closed, owing to can increase the tightness between valve gap and drain pipe.Under the effect that does not have hydraulic pressure, spring backs down valve gap automatically, the bounding means of middle shaft rear end can prevent that spring is in flicking process, axis also can break away from support thereupon, as when need not to use drain valve, can add in the rear end of drain pipe an end cap, with bolt end cap and drain pipe are fixed, prevent that earth etc. from entering drain pipe, and cause obstruction.
The utility model prevented in subterranean tunnel effectively owing to having adopted above technological scheme, is subject to the harm that the interference of water causes when meeting water, can automatically get rid of water, guaranteed the safe operation of underground tunnel system.

Embodiment
Understanding for to structure of the present utility model describes below in conjunction with drawings and Examples.
At first in conjunction with shown in Figure 2, the utility model is used for the anti-drain valve that floods a 1A of subterranean tunnel, be installed in the basic 2A of subterranean tunnel, comprise a drain pipe 1, be installed with a support 2 in the drain pipe 1, the end, rear end of drain pipe 1 forms a flange head 3, front end at drain pipe 1 is provided with a valve gap 4, and drain valve also comprises an axis 5, and the front end of axis 5 runs through the middle part of valve gap 4, and by a nut 6 that axis 5 is fixing with valve gap 4, support 2 is run through in the rear end of axis 5, a sheathed spring 7 on axis 5, and spring 7 is installed with between valve gap 4 and support 2, and cooperate support to be provided with a bounding means 8 in the end, rear end of axis 5, with bolt 9 that bounding means 8 is fixing with axis 5.
Again in conjunction with shown in Figure 3, at first axis 5 is packed into the front end of drain pipe 1, support 2 is run through in the rear end of axis 5, end, rear end at axis 5 is fixing with axis 5 with bounding means 8 with bolt 9, at axis 5 cover upper springs 7 and valve gap 4, and in the front end sleeve upper cap nut 6 of axis 5 and tighten, in order to increase the sealing of valve gap 4, at side increase by one sealing gasket 10 of valve gap 4 over against drain pipe 1, at last drain valve is packed in the basis of subterranean tunnel bottom, flange head 3 is in outside the basis, and can realizes application target.
Valve gap 4 is in the situation that without hydraulic pressure or the less opening state that all is in of hydraulic pressure, can come draining by drain pipe 1, when the depth of water of upstream face reaches preset height, hydraulic pressure surpasses the pressure maximum that spring 7 can bear, the valve gap 4 of water pressure pushing drain valve, make its Compress Spring 7 until valve gap 4 is close to drain pipe 1, with drain pipe 1 sealing, under the effect that does not have hydraulic pressure, spring 7 backs down valve gap 4 automatically, the bounding means 8 of end, axis 5 rear end can prevent spring 7 in backing down process, and axis 5 also breaks away from support 2 thereupon.
As another better embodiment of the present utility model, as shown in Figure 4, can utilize flange head 3 fastening installation one end caps 11 of the end, rear end of drain valve, can avoid like this installing this drain valve process in earth enter in the drain pipe 1.
The utility model prevented effectively in subterranean tunnel, is subject to the harm that the interference of water causes when running into current, can automatically get rid of water, guaranteed the safe operation of the railway system.
