Abstract
The utility model discloses an I-shaped one-way vent valve which is characterized by comprising a gas exhausting device (1), a valve body (2) and a gas collecting device (3). The valve body (2) is mounted on the upper portion of the gas collecting device (3). The gas exhausting device (1) is mounted on the upper portion of the valve body (2). A movable valve rod (5) is mounted on an upper cover body (4) of the valve body (2), and an air inlet (7) is arranged in a lower cover body (6). An upper valve cover (8) and a lower valve cover (9) are respectively mounted at the upper end and the lower end of the movable valve rod (5). The upper cover body (4), the upper valve cover (8), the lower cover body (6) and the lower valve cover (9) are respectively provided with a magnet (10). The I-shaped one-way vent valve is simple in structure, flexible in motion, capable of guaranteeing safety operation of geomembrane seepage-proof engineering, and capable of being widely applied to geomembrane seepage-proof technology of reservoirs, watercourses and the like.
Description
Technical field
The utility model relates to a kind of Novel check valve that is applied to geomembrane, specifically relates to a kind of reservoir that is applied to when preventing that foundation leakage from adopting the geomembrane technology, the one-way valve that arranges at geomembrane.
Background technique
When building reservoir; often because of the base seepage; and can not well finish the purpose of reservoir filling; therefore; the about 0.5 millimeter geomembrane of laying one deck of water reservoir base gross area of being everlasting is made impervious barrier; cover with thick about 0.5 meter sedentary soil again and make protective layer on the geomembrane; anti-seepage effect is better; but when reservoir level was higher, base soil was owing to being sunk by effect of water pressure, and the gas in the interstices of soil is forced to discharge savings below geomembrane; film is produced very large jacking pressure; when the pressure of some areas greater than protective layer soil, very thin geomembrane can by bursting, cause the failure of seepage control project.Existing way has: one, and the thickness of increase protective coating soil is so that the gravity of protective layer soil is greater than the pressure of film below gas.Two: below film, lay breather line, so that the pressure of gas can be not excessive.Though these two kinds of possibilities that method can both address this problem, all can increase engineering cost with strengthen difficulty of construction, and the first scheme is a difficult problem for the effective thickness that calculates protective coating soil, the first scheme breather line can be because earth etc. and blocked.Therefore two schemes all has shortcoming, can not be widely used.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, providing a kind of can effectively solve because reservoir level is higher, so that the air pressure under the geomembrane is higher, destroys the problem of geomembrane, thereby guarantee the I-shaped one-way exhaust valve of the normal operation of reservoir seepage-proofing engineering.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
A kind of I-shaped one-way exhaust valve, it is characterized in that: it comprises venting gas appliance, valve body and gas-collecting device, described valve body is installed in gas-collecting device top, venting gas appliance is installed in valve body top, movable valve rod is installed on the upper cover body in the described valve body, lower cover is provided with inlet hole, and movable valve rod is separately installed with bonnet and bottom flange in two ends up and down, and magnet all is installed on upper cover body, bonnet and lower cover, bottom flange.
Described venting gas appliance is the inverted U outlet pipe.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, the valve body flexible movements can be guaranteed the operation of geomembrane anti-seepage engineering safety.The parameter designing that this one-way exhaust valve provides can be produced in batches in factory, is widely used in reservoir, and the geomembrane anti-seepages such as river course are technical.
Description of drawings
Fig. 1 is the utility model overall schematic.
Fig. 2 is the utility model valve body schematic representation.
Fig. 3 is the utility model gas-collecting device figure.
Fig. 4 is the utility model venting gas appliance figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1-4, it includes venting gas appliance 1, valve body 2 and gas-collecting device 3 the utility model.Valve body 2 is installed in gas-collecting device 3 tops, and venting gas appliance 1 is installed in valve body 2 tops.Movable valve rod 5 is installed on the upper cover body 4 in the valve body 2, lower cover 6 is provided with inlet hole 7, movable valve rod is separately installed with bonnet 8 and bottom flange 9 in two ends about in the of 5, on upper cover body 4, bonnet 8 and lower cover 6, bottom flange 9, magnet 10 is installed all, can guarantee that valve shaft can get back to the origin-location after exhaust, can strengthen again the sealing of outlet valve, guarantee that this one-way exhaust valve is water-tight.
Described venting gas appliance 1 is the inverted U outlet pipe, when water enters outlet pipe, can strengthen original gas pressure intensity in the outlet pipe, thereby guarantees that water can not flow to valve inner.
Such as Fig. 3, gas-collecting device 3 includes gas collection ball 12, and gas collection ball 12 is by the duroplasts manufacturing, and the rough sand gravel is filled in inside.Can increase some apertures 11 more on the surface of gas collection ball 12, thereby increase exhaust velocity, add the last layer filter layer on the surface of gas collection ball, be to be covered by earth etc. for the aperture that prevents the gas collection ball.
During implementation; geomembrane is bonded in the top of venting gas appliance; this one-way exhaust valve vertically is fixed on below the earth (protective layer), the outlet pipe 13 of venting gas appliance is stretched out earth put (can add one section plastic tube one section of outlet pipe is put in the water) in the water into again.
In use, can place one-way valve at place, regular hexagon summit, the concrete size of one-way valve can be according to suitable the making a change of seepage control project, and one-way valve can be according to size and the intensity of the intensity adjustment magnet of water level and geomembrane, thereby make the reliability of geomembrane and Security all very high.The fully requirement of seepage control project.
Geomembrane is by preventing in position one-way exhaust valve, and the pressure that can effectively solve geomembrane bottom gas is excessive, destroys the problem of geomembrane.Namely increase the working life of geomembrane, prevented again the seepy question of reservoir.Simple in structure, be fit to a large amount of production.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
