Abstract
The utility model provides an anti-seepage pressure-reducing valve for irrigation ditches. An anti-seepage gasket (4) is arranged on a bearing plate (3) provided with an eccentric orifice (2), the bearing plate (3) is arranged on the interior upper part of a circular sleeve barrel (1), the anti-seepage gasket (4) is pressed by an aluminum piece (5), the two ends of the circular sleeve barrel (1) are wrapped by nonwoven geotextile (6) and are buckled by ferrules (7), and a concave groove (8) and a mark (9) are carved on the outer wall of the circular sleeve barrel (1). Therefore, groundwater can flow into the irrigation ditches, water in the irrigation ditches do not seep, and the utility model provides a protecting device for the anti-seepage layers of the irrigation ditches.
Description
The utility model relates to and is used to get rid of the phreatic device in the anti-seepage of channels layer back side in a kind of hydraulic engineering, is a kind of unidirectional water-through valve.
In hydraulic engineering, be using water wisely, guarantee to irrigate, concrete commonly used or plastic sheeting etc. are at channel surface construction impervious barrier.For the canal section of winding or the side of deep-cutting, because phreatic effect often makes concrete anti-seepage layer cracking, plastic sheeting impervious barrier bubbling influences anti-seepage effect.
For getting rid of underground water, the way of Cai Yonging was that " pressure reducer " is installed in anti-seepage of channels layer in the past, its number of patent application is 91212165.3, this pressure reducer, because inner impervious film directly bears the effect of water pressure, easy deformation and breaking, stagnant water effect is poor, and bearing plate is positioned at the round buss bottom, needs to fill sponge in the round buss and makes impervious film location, has hindered current like this and has passed through.
The purpose of this utility model is to overcome above-mentioned deficiency, impervious film is changed into impervious packing ring, pressing aluminium flake on it, bearing plate is risen to the round buss internal upper part, so just can bear water pressure by aluminium flake, and do not need the sponge in the round buss, thereby strengthened durability, the sealing of device and crossed water-based.
The utility model is achieved in that on the bearing plate of the band eccentric orfice that is installing on the top in a round buss, put an impervious packing ring, pressing sheet metal on it, the two ends of round buss are with the non-woven geotextile wrapping and buckle cranse, the outer wall of round buss is carved with groove, and leaves mark.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is the longitudinal plan of utility model.
With reference to accompanying drawing, the inside of plastics round buss (1), about 1 centimeters apart from the top, the plastics bearing plate (3) of a band eccentric orfice (2) is installed, puts an impervious packing ring (4) on it, it adopts rubber or plastics to make, above aluminium flake (5) is pressed in, cranse (7) is wrapped up and buckled in the two ends of round buss (1) with non-woven geotextile (6), and the outer wall of round buss (1) is carved with groove (8), and leave the direction of mark (9) with difference eccentric orfice (2).
Under the water effect, impervious packing ring (4) and aluminium flake (5) are pushed against together on bearing plate (3) in channel, and eccentric orfice (2) can not seep water; Under groundwater effect, impervious packing ring (4) and aluminium flake (5) are separated by jack-up and bearing plate (3), and underground water plays depressurization in eccentric orfice (2) flows into canal.
This device can prevent the cracking of concrete canal impervious barrier and the bubbling of plastic sheeting anti-seepage of channels layer effectively, reaches the purpose of safe water-saving.
Claims (1)
1, a kind of anti-seepage of channels reducing valve, it is by round buss (1), bearing plate (3) non-woven geotextile compositions such as (6), it is characterized in that: on the bearing plate (3) of the band eccentric orfice (2) that the top in round buss (1) is being adorned, put an impervious packing ring (4), pressing aluminium flake (5) on it, cranse (7) is wrapped up and buckled in the two ends of round buss (1) with non-woven geotextile (6), and the outer wall of round buss (1) is carved with groove (8) and mark (9).
