Abstract
The utility model discloses a bionic heart valve air-exhausting device, composed of a bionic heart valve structure (1), a round penetrating pipeline (2), a filter screen (3) and a hard framework (4), wherein the bionic heart valve structure (1) is located at the upper part of a vent valve and composed of three valves (3) open upwards; the hard framework (4) is arranged inside the bionic heart valve structure (1) so as to support the bionic heart valve structure (1); the lower part of the bionic heart valve structure (1) is directly connected with the round penetrating pipeline (2); the filter screen (3) is arranged in the round penetrating pipeline (2); and in-situ earth layer which is about 0.5m thick covers the round penetrating pipeline (2). The bionic heart valve air-exhausting device avoids blockage and leakage of the pipeline, and is high in anti-pressure ability, long in service life, wide in application range and convenient for industrialized production; besides, the bionic heart valve air-exhausting device effectively prevents the blasting phenomenon of the geomembrane.
Description
Technical field
The utility model relates to exhaust plant under a kind of Wall in Plain Reservoir geomembrane film, specifically relates to exhaust plant under a kind of geomembrane of copying heart film lobe operating principle.
Background technology
When building the water storage projects such as reservoir, He Ba, dyke; normal gene basis seepage must be laid one deck Novel seepage material at bottom of the reservior, river gross area, and a kind of thickness approximately geomembrane of 0.5mm is made impervious barrier; do heavily protection of lid with thick approximately 0.5m original place soil again, anti-seepage effect is fine.But when Dang He, storehouse periphery underground water exceeds reservoir level, because pressure reduction produces one jacking pressure to geomembrane under film, surpass when cover heavy soil weight when pressure increases, very thin geomembrane causes seepage control project failed namely by bursting.The method of preventing and treating in the past is that increase is pressed in the thickness of geomembrane loam cake heavy soil, namely gains in weight.Every interval 30m left and right sides perforate (diameter 20cm) on geomembrane places the aperture to cover " mud cake " of the clay work of water again, and when pressure is large, the geomembrane bottom pressure will back down " mud cake " and carry out drainage exhaust, and after pressure reduced, " mud cake " fell after rise.Special exhaust plant links to each other with geomembrane, when film press down powerful in the device on the time with regard to Exhaust Gas.First increases construction costs and difficulty of construction above three kinds of methods; Second because " mud cake " probably displacement or be pulled away when draining gas causes artificial leak paths; The problem that last probably silts up is also brought larger process and assemble difficulty simultaneously, and therefore above three kinds of methods are all unreasonable, can not guarantee the engineering safety operation.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, and the enhancing exhaust performance is provided, and improves the bionic heart film lobe exhaust plant of the flexibly exhaust of exhaust efficiency.
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 bionic heart film lobe exhaust plant, it is characterized in that: comprise that imitative heart film lobe structure, cylinder pipe, filter screen, rigid frame form, described imitative heart film lobe is configured to the main body of whole device, with the cylinder pipe positioned vertical on geomembrane, at the inner filter screen of placing of cylinder pipe, under imitative heart film lobe structure film lobe, fix with rigid frame.
Compared with prior art, the beneficial effects of the utility model are:
In the situation that imposed load is less, counterweight by self is exerted pressure, can closing seam, when imposed load increases gradually, based on its rigid-framed structure characteristic, the sealing of outlet valve can promote so, has prevented in the situation that water pressure is excessive, hydraulic pressure damages the obturator of outlet valve or seepage by pressure, and causing little people from position is the possibility of leaking.Because the outlet valve of other materials is compared in being made by rubber of film lobe itself, its corrosion resistance, seal are all slightly better, have increased the working life of outlet valve, have saved certain maintenance cost simultaneously.
Description of drawings
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is two of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, the utility model is comprised of imitative heart film lobe structure 1, cylinder pipe 2, filter screen 3, rigid frame 4, imitative heart film lobe structure 1 is positioned at the end of outlet valve, 3 rubber membrane lobes by upward opening form because rubber has hydrophobicity and certain cohesive, three rubber membrane lobes are mutually bonding airtight under free state, rubber membrane lobe inside is supported by rigid frame 4, and its underpart directly links to each other with cylinder pipe 2, is provided with filter screen 3 in the cylinder pipe 2.
Imitative heart film lobe is constructed 1 upward opening, and the tip up, and wherein the rigid frame 4 that has of the frame characteristic that can take full advantage of rigid-framed structure increases the compressive property of imitative heart film lobe structure 1.In the situation that passive state or above have the imitative heart film lobe structure 1 of load all can tight closure, when the air pressure under the geomembrane surpasses the film upward pressure, gas can import in the water by imitative heart film lobe structure 1 under the film, bear in the scope of pressure in rigid frame 4 maximums simultaneously, pressure is larger, its seal is stronger, has avoided the phenomenon such as leak under the high load that other geomembranes exist to prevent from pouring in down a chimney.When air pressure under the geomembrane is lower than in the cylinder pipe 2 hydraulic pressure, imitative heart film lobe structure 1 state that closes that is in as shown in the figure; But when air pressure under the film is higher than in the cylinder pipe 2 hydraulic pressure, imitative heart film lobe structure 1 just can exhaust outside cylinder under the effect of air pressure under the film, three film lobes of imitative heart film lobe structure 1 open exhaust, the effect of filter screen 3 is to prevent that gas carries certain silt when outside exhaust under geomembrane, these tiny particles adhere at imitative heart film lobe structure 1, affect its seal, and its shortcoming is to result in blockage, but drawing gas according to theory is having under the structure in space and can derive freely, can't result in blockage because of the gathering that silt is arranged, owing to having determined it, the size of installing the aperture can not estimate too much bulk silt simultaneously, therefore filter screen 3 can not affect the usability of device.
During use, in the certain distance in interval on the geomembrane exhaust plant under as shown in Figure 1 the imitative heart film valve is set, such as every 1.5m or 2.0m arranges exhaust plant under the imitative heart film valve.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
