The structure and the working principle of the one-way drain valve and the composite ecological geomembrane comprising the same provided by the invention are further described in detail with reference to the attached drawings.
Fig. 1 is a schematic structural view of a preferred embodiment of a one-way drain valve according to the present invention. The structure of the one-way drain valve comprises a water inlet cylinder 1 provided with a wing-shaped chassis 10 and a periphery provided with a lateral water outlet hole 14, an outer cylinder mechanism 2 provided with a base 21 and a periphery provided with a water outlet hole 22 corresponding to the lateral water outlet hole 14, an arch-shaped (arc-shaped) protective cover mechanism 3 and an elastic sealing plug mechanism 4; the outer cylinder mechanism 2 and the water inlet cylinder 1 can be relatively fixed through a screw mechanism 15 (or a general non-extractable inverted tooth clamping groove mechanism), and the up-down relative position (distance) between the wing-shaped chassis 10 of the water inlet cylinder and the base 21 of the outer cylinder mechanism can be adjusted to clamp the geomembrane layer forming the composite ecological geomembrane; the protective cover mechanism 3 in an arch (arc) structure is buckled on the outer cylinder mechanism 2, and the protective cover mechanism and the outer cylinder mechanism are fixedly connected through a screw mechanism 16 (of course, a common non-extractable inverted tooth clamping groove mechanism can also be adopted); the elastic sealing plug mechanism 4 is a columnar body 41 (i.e. a sealing plug body capable of realizing the opening and closing of the water inlet cylinder 1) which is arranged in the middle and can be inserted into the water inlet cylinder 1, the periphery of the elastic sealing plug mechanism is a wing ring structure 42 which is made of rubber plastic (rubber) materials and can be fixed with the inner wall of the protective cover mechanism and has an elastic extension function, and the columnar body 41 can move along the axial direction of the columnar body to realize the opening and closing of water outlet holes 14 arranged on the periphery of the water inlet cylinder; a space gap 31 for the pillar-shaped body 41 to move up when the water outlet hole 14 is opened is provided between the elastic sealing plug mechanism 4 and the inner arch surface 32 of the arch (arc) protection cover mechanism 3.
The working principle of the one-way drain valve is that after the water in the foundation reaches a certain pressure, the elastic sealing plug mechanism 4 inserted into the water inlet cylinder 1 is pushed up to a certain displacement (the wing ring structure 42 is elastically extended) through the water inlet 17 forming the water inlet cylinder 1, so that the water outlet holes 14 on the periphery of the water inlet cylinder are opened, and the water in the foundation flows out of the one-way valve body through the water outlet holes and the water flowing holes 22 on the outer cylinder mechanism 2; after the water pressure in the foundation is reduced, the wing ring structure 42 elastically contracts to restore the cylindrical body 41 of the elastic sealing plug mechanism 4, so as to close the water inlet 17 of the water inlet cylinder 1.
In the structure constituting the above-mentioned one-way water discharge valve,
the connection and fixation mode of the protective cover mechanism 3 and the outer cylinder mechanism 2 in the arch (arc) structure can be as follows: the protective cover mechanism 3 in an arch (arc) structure is buckled on the outer cylinder mechanism 2, and the protective cover mechanism and the outer cylinder mechanism are fixedly connected through a screw mechanism 16 (of course, a common non-extractable inverted tooth clamping groove mechanism can also be adopted); of course, since the components are in the length of centimeters, in order to better realize the connection and fixation between the protective cover mechanism 3 and the outer cylinder mechanism 2 in an arch-shaped (arc-shaped) structure, the outer cylinder mechanism 2 and (the outer wall or the inner wall of) the protective cover mechanism 3 can be combined together in a mode of adhesive bonding or heat seal welding;
the connecting structure of the elastic sealing plug mechanism 4 and the inner wall of the protective cover mechanism is that a rib groove structure 33 with a cross section is arranged on the inner wall forming the protective cover mechanism, a rib 43 corresponding to the rib groove structure is arranged around a wing ring structure 42 of the elastic sealing plug mechanism, and the rib groove structure and the rib ring structure are buckled, connected and fixed; of course, in order to adjust the position between them, the groove structure 33 can be designed into preferably 2-3 grooves 34 corresponding to the above-mentioned ribs 43, so as to adjust the up-and-down position of the elastic sealing plug mechanism 4 in the shield mechanism; of course, the connection structure of the elastic sealing plug mechanism 4 and the inner wall of the protective cover mechanism can also be a fixed connection structure bonded (or welded) by an adhesive;
-forming the outer cylinder mechanism
The top 23 may be an open structure as shown in fig. 1, that is, the outer wall of the outer cylinder mechanism is fixed with the inner wall of the protective cover mechanism 3 by a screw mechanism 16 in a screw (or a snap), and the top cylinder opening 18 of the water inlet cylinder 1 directly jacks up the wing ring structure 42 of the elastic sealing plug mechanism 4. When the water pressure of the foundation is high, the wing ring structure 42 can be jacked up, so that water outlet gaps 44 (see fig. 4) are formed around the wing ring structure, high-pressure water of the foundation can flow out of the water outlet holes 14 and can enter the outer cylinder mechanism 2 through the water outlet gaps, and the large water amount of the foundation can be discharged; the structure can also be a closed structure as shown in fig. 2, namely, the outer cylinder mechanism 2 is composed of a base 21, an outer cylinder wall 24 and a top cover 23 which is spirally fixed relative to the cylinder wall of the water inlet cylinder 1, and the structure can increase the integral strength of the outer cylinder mechanism 2;
the structure shown in fig. 3 may also be adopted, that is, the outer cylinder mechanism 2 is composed of a base 21 and ribs 25 with solid upper portions and arranged at intervals, water flow holes 22 corresponding to the water outlet holes 14 around the water inlet cylinder 1 are arranged among the ribs, and a screw structure capable of being relatively fixed with the inner wall of the protective cover mechanism 3 through a screw mechanism 16 (of course, an undetachable inverted tooth clamping groove mechanism may also be adopted) is arranged on the outer side of the upper portion of the ribs. The structure of the outer cylinder mechanism is more firm and more practical;
when the structure of the outer cylinder mechanism is the structure with the top cover 23 as shown in fig. 2, or the structure with the base 21 and the solid ribs 25 forming the space as shown in fig. 3, the ribs 43 arranged around the wing ring structure 42 of the elastic sealing plug mechanism 4 can be fixed in the slots 26 at the top of the top cover 23 or the ribs 25 of the outer cylinder mechanism, so that the elastic sealing plug mechanism 4 can be fixed, and the function of opening and closing the water outlet hole 14 of the water inlet cylinder can be realized;
the shape of the columnar body 41 forming the elastic sealing plug mechanism is matched with that of the inner cylinder body of the water inlet cylinder 1, so that the water outlet hole 14 can be opened and closed when the columnar body 41 moves up and down along the axis of the columnar body; the column body 41 can be a cylindrical structure matched with the inner cylinder body of the water inlet cylinder 1, or can be a matched inverted trapezoid structure with the axial section being long at the upper side 46 and narrow at the bottom side 45, the column body 41 with the inverted trapezoid structure can better realize the opening and closing of the water outlet hole 14, and the high water pressure of the foundation can jack the wing ring structure 42 to form a water outlet gap 44 (see fig. 4), so that the function of discharging the large water quantity of the foundation is met;
the wing ring structure 42 forming the elastic sealing plug mechanism is made of rubber material with stretching and shrinking properties, and has the function of stretching when the water arch pillar body 41 on the high-pressure foundation is lifted upwards, so that the pillar body 41 moves upwards and the water outlet hole 14 is opened; when the water pressure in the foundation is reduced, it naturally contracts the cylindrical body 41 to move downwards and close the water outlet hole 14. Therefore, the wing ring structure 42 can be a solid integral structure, and the integral wing ring structure 42 has great pulling force, so that the wing ring structure is only suitable for areas with high water pressure of the foundation; the wing ring structure 42 can also be a radial ring structure formed by a plurality of fixing strips 421, 422, 423 and … 425 (preferably 3 or 4 strips are more suitable, namely the purpose of stretching can be achieved, and the balance can be achieved when the columnar body 41 is displaced up and down to prevent the columnar body from deviating and dislocating with the inner cylinder body of the water inlet cylinder 1 when the columnar body is displaced down to cause the water leakage phenomenon of the water outlet hole 14) which is made of rubber materials as shown in fig. 3, the wing ring structure 42 of the structure has relatively small pulling force, and the columnar body 41 can be easily arched by foundation water to achieve the purpose of opening the water outlet hole 14.
As shown in fig. 4, it is a schematic structural view of a one-way drain valve that can be manufactured to have the thinnest thickness (height) according to the present invention. The one-way drain valve of this structure is to reduce the thickness (height) of the water inlet cylinder 1 and the outer cylinder mechanism 2 sleeved with it on the basis of fig. 1, the periphery of the water inlet cylinder is not provided with water outlet holes 14, and at the same time, the columnar body 41 for opening and closing the cylinder opening of the water inlet cylinder 1 is provided as a film-shaped plug body. After the water in the foundation reaches a certain pressure, the film-shaped column body 41 of the elastic sealing plug mechanism 4 blocked at the cylinder opening of the water inlet cylinder 1 is jacked up (the wing ring structure 42 elastically extends) through the water inlet 17 forming the water inlet cylinder 1, so that a water outlet gap 44 is formed around the cylinder opening of the water inlet cylinder, and the water in the foundation flows out of the one-way valve body through the gap along an arrow F; after the pressure of water in the foundation is reduced, the wing ring structure 42 elastically contracts to restore the cylindrical body 41 of the elastic sealing plug mechanism 4, so that the opening of the water inlet barrel 1 is closed.
Fig. 5 is a schematic structural view of a composite ecological geomembrane provided by the present invention. The structure of the composite ecological geomembrane comprises an ecological geomembrane part 6 and a plurality of one-way drain valves A (a plurality of vertically and horizontally arranged) which are sequentially arranged in the ecological geomembrane part; wherein, the ecological geomembrane 6 comprises a lower permeable geotextile layer 62, a geomembrane layer 64 provided with a fixing hole 63 and an upper permeable geotextile layer 61 covering the geomembrane layer; wherein the one-way drain valve A passes through the fixing hole 63 and is clamped between the lower permeable geotextile layer 62 and the upper permeable geotextile layer 61; meanwhile, the distance between the wing-shaped chassis 10 and the base 21 which form the one-way drain valve can be adjusted (screwed) to clamp and fix the geomembrane 64.
The working principle is as follows: in the use process of the composite ecological geomembrane, the lower permeable geotextile layer 62 is contacted with a base surface, seepage water of a foundation permeates into the water inlet 17 of the water inlet cylinder forming the one-way drain valve A through the lower geotextile layer and is discharged out of the valve body, and the upper permeable geotextile layer 61 covered by the lower permeable geotextile layer is discharged, so that the one-way discharge of high-pressure water of the foundation is realized, and the safe operation of water conservancy engineering is ensured.
In the structure constituting the above-described one composite ecological geomembrane:
in order to further improve the water permeability efficiency of the composite ecological geomembrane and reduce the number of the one-way drain valves A,
a plurality of lugs 65 are arranged between the geomembrane layer 64 and the lower permeable geomembrane layer 62 to form a water guide duct 66 between the two; the seepage water of the foundation permeates into a water guide duct 66 consisting of a geomembrane 64 and a lug 65 through the lower geotextile 62, is discharged out of the valve body through a water inlet 17 of a water inlet cylinder passing through the one-way drain valve A, and is finally discharged through the upper seepage geotextile 61, and no water is discharged when the internal and external water pressure of the slope-attached one-way drain geomembrane is balanced or the seepage water in the slope foundation has no pressure.
In order to enlarge the effective drainage area and the drainage volume of the one-way drainage valve and prevent the lower permeable geotextile layer 62 from being adhered to the bottom of the wing-shaped chassis 10 of the drainage valve water inlet cylinder to form the blockage of the water channel in the process of preparing the composite ecological geomembrane, the water guide disc mechanism 5 formed by the radial ribs 51 shown in fig. 6 is arranged at the bottom of the wing-shaped chassis 10 forming the one-way drainage valve water inlet cylinder, namely, the water penetrating into the water guide duct of the lower permeable geotextile layer is collected into the water inlet 17 through the water guide groove 52 formed between the radial ribs of the water guide disc mechanism 5 and is discharged out of the valve body.
In order to smoothly discharge the water discharged from the one-way drain valve through the upper water-permeable geotextile layer 61, the upper water-permeable geotextile layer 61 covers the arch-shaped protective cover mechanism 3 constituting the one-way drain valve, and a water discharge space 67 is formed between the periphery of the arch-shaped protective cover mechanism and the geotextile layer.
In the structure of the composite ecological geomembrane, because the columnar body 41 and the wing ring structure 42 of the elastic sealing plug mechanism 4 for realizing the switching function in the one-way drain valve are made of rubber plastic (rubber) materials with elastic extension function, the one-way drain valve can be made into a structure with the thickness (height) of 2-3 cm and arranged in the ecological geomembrane with the thickness of 2-3 cm, the thickness of the integral composite ecological geomembrane structure can be controlled between 3-5 cm, the composite ecological geomembrane can be curled and can be directly paved on an engineering foundation for use, and the composite ecological geomembrane has the characteristic of convenient construction and use; the pressure water in the foundation is discharged out of the anti-seepage lining structure layer through the one-way drain valve of the composite ecological geomembrane, so that the internal and external balance of the water pressure is achieved, and the operation safety of the hydraulic structure can be ensured.
