Detailed Description
The structure and the working principle of the one-way drain valve provided by the present invention will be further described in detail with reference to the accompanying drawings.
Fig. 2 is a schematic structural view of a preferred embodiment of the 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 arched (arc) protective cover mechanism 3 and an elastic sealing plug mechanism 4; the outer cylinder mechanism 2 and the water inlet cylinder 1 are relatively fixed through a screw mechanism or a pawl clamping groove mechanism 15, and the distance between the wing-shaped chassis 10 of the water inlet cylinder and the base 21 of the outer cylinder mechanism is adjustable and used for clamping a 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 through a screw mechanism 16; the elastic sealing plug mechanism 4 comprises a cylindrical sealing plug body 41 (i.e. capable of realizing the opening and closing of the lateral water outlet hole 14 of the water inlet cylinder) which can be inserted into the water inlet cylinder 1 and a flexible structure 43 which is fixed on the upper part of the cylindrical sealing plug body and is connected with the cylindrical sealing plug body into a whole structure and can be deformed, preferably into a spherical shape.
The working principle of the one-way drain valve is that after the water in the foundation reaches the set pressure, the columnar sealing body 41 inserted into the water inlet cylinder 1 is pushed up through the water inlet 17 forming the water inlet cylinder 1, then the spherical soft structure 43 is extruded to rise and is squashed by the inner wall 32 of the protective cover mechanism 3, 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 spherical soft structure 43 elastically contracts and presses down the cylindrical sealing body 41 of the elastic sealing plug mechanism 4 to restore the original state, and the water inlet 17 of the water inlet barrel 1 is closed.
In the structure constituting the above-mentioned one-way water discharge valve,
when the inner wall of the protective cover mechanism is in an arch structure as shown in fig. 2, since the spherical surface of the soft structure forming the elastic sealing plug mechanism is matched with the inner wall, i.e. the top of the soft structure is sunk into the concave inner wall 32 forming the arch-shaped protective cover mechanism, the displacement and sliding between the two can be effectively prevented, and therefore, the two can be connected without adhesion; when the inner wall 32 of the shield mechanism is a planar structure as shown in fig. 3, since the spherical surface of the soft structure constituting the elastic sealing plug mechanism is not matched with the spherical surface, i.e. the spherical top 431 of the soft structure is easy to displace and slide when being extruded with the planar top 32 of the shield mechanism, so as to cause dislocation when the cylindrical sealing body 41 of the elastic sealing plug mechanism 4 is pushed up, the top 431 of the soft structure is preferably adhered and fixed with the planar inner wall 32 of the shield mechanism;
the soft body structure forming the elastic sealing plug mechanism is formed by a solid body made of an elastic material as shown in fig. 2; it can also be made up of sealing body 432 made of elastic material and liquid 433 filled in as shown in fig. 3; the two forms of structures can realize the elastic action of compression deformation thinning and resetting thickening, but the soft structure consisting of the sealing body 432 and the liquid 433 filled in the sealing body has larger deformation; the solid soft structure has less deformation but is relatively more stable;
the shape of the columnar sealing plug body 41 forming the elastic sealing plug mechanism is matched with the shape of the inner cylinder body of the water inlet cylinder 1, so that the water outlet hole 14 of the columnar sealing plug body 41 can be opened and closed when the columnar sealing plug body moves up and down along the axis of the columnar sealing plug body 41; the cylindrical 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 a long upper edge 46 and a narrow bottom edge 45 in the axial section as shown in fig. 2 or fig. 3, and the cylindrical sealing body 41 with the inverted trapezoid structure can better realize the opening and closing of the water outlet hole 14;
the bottom of the soft structure is provided with a wing ring structure 47 capable of being lapped on the upper end part of the water inlet cylinder, so as to prevent the foundation water in the normal high-pressure range from being difficult to jack up and causing the failure of the switching function because the sealing plug body 41 which is plugged in the cylinder body in the water inlet cylinder 1 and is in a column or inverted trapezoid structure is sucked when the water pressure of the foundation is lower; of course, as shown in fig. 3, the column support mechanism 5, which is composed of a plurality of protrusions 51 or a cross-shaped bracket having a water inlet 53 structure and composed of a stay 52 shown in fig. 6, is provided on the inner wall 11 of the lower portion of the water outlet hole constituting the water inlet cylinder, and the above-mentioned functions can be also realized;
-forming the outer cylinder mechanism
The top of the structure can be an open 23 structure as shown in fig. 3, when the water pressure of the foundation is high, the wing ring structure 47 can be jacked up, so that water outlet gaps 44 (see fig. 5) are formed around the wing ring structure, and high-pressure water of the foundation can flow out of the water outlet holes 14 and enter the outer cylinder mechanism 2 through the water outlet gaps, so that the large water 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, an inner wall 26 which is spirally fixed relative to the cylinder wall of the water inlet cylinder 1 and a top cover 27, and the structure can increase the integral strength of the outer cylinder mechanism 2;
the structure shown in fig. 4 may also be adopted, that is, the outer cylinder mechanism 2 is composed of a base 21 and ribs 25 with solid upper parts 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 the outer side of the upper part of the ribs is provided with a screw structure 15 capable of being fixed relatively to the inner wall of the protective cover mechanism 3. The structure of the outer cylinder mechanism is more firm and more practical;
as shown in fig. 5, it is a schematic structural view of a one-way water discharge valve capable of being manufactured to have the thinnest thickness (height) according to the present invention. The one-way drain valve of the structure reduces the thickness (height) of the water inlet cylinder 1 and the outer cylinder mechanism 2 sleeved with the water inlet cylinder on the basis of figure 2, figure 3 or figure 4, the periphery of the water inlet cylinder is not provided with water outlet holes 14, and meanwhile, the elastic sealing plug mechanism 4 for realizing opening and closing of the cylinder opening of the water inlet cylinder 1 is composed of a spherical soft body structure 43 and a sealing plug body 41 which is arranged not to penetrate into the water inlet cylinder but only plugs the cylinder opening. After the water in the foundation reaches a certain pressure, the upper part blocked at the opening of the water inlet cylinder 1 is a plug body 41 to jack up a flattened spherical soft body structure 43 through the water inlet 17 forming the water inlet cylinder 1, so that a water outlet gap 44 is formed around the opening of the water inlet cylinder, and the water in the foundation flows out of the one-way valve body from the gap along an arrow F; after the water pressure in the foundation is reduced, the spherical soft structure 43 elastically contracts to enable the sealing body 41 to be reduced and restored to the original state, and the opening of the water inlet barrel 1 is closed.
The soft body structure constituting the elastic sealing plug mechanism may be a deformable spherical (arc) type structure as shown in fig. 2, 4 and 5, or a spherical structure as shown in fig. 3. However, in order to avoid that the silt will enter between the upper spherical surface (cambered surface) of the soft structure and the inner wall 32 of the protective cover mechanism 3 during the water absorption and drainage processes of the one-way valve, so that the deformation effect is deteriorated and the switching performance of the sealing body 41 is affected, the soft structure 43 is a trapezoidal column-shaped structure with a large upper top surface 434 and a small lower bottom surface 435 as shown in fig. 6, so that the silt flowing back into the protective cover mechanism can be effectively prevented from affecting the deformation space of the column-shaped soft structure 43, and the reliability of the one-way drainage valve is improved;
the column-shaped body support mechanism 5 composed of a plurality of convex blocks 51 or a support rod 52 shown in fig. 7 and having a water inlet hole 53 structure is arranged on the inner wall (preferably the contact part with the sealing body 41) of the water inlet cylinder of the one-way drain valve shown in fig. 5 and 6, so as to prevent the sealing body 41 from being sucked into the cylinder mouth of the water inlet cylinder 1 when the water pressure of the foundation is low, thereby preventing the foundation water in the normal high-pressure range from being difficult to jack up and causing the failure of the switching action.
