Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a hydraulic flotation valve. Background Art

[0002] Water storage and drainage is an important part of urban infrastructure construction. It is directly related to the city's flood control and drainage capabilities, the rational use of water resources, and the quality of life of residents. The following is the current status and development trends of water storage and drainage:

[0003] 1) Urban drainage system.

[0004] Pipeline network expansion and renovation: With the acceleration of urbanization, the old drainage pipeline network can no longer meet the growing demand, so many cities are expanding and renovating the drainage pipeline network.

[0005] Intelligent management: Use IoT technology to monitor the drainage system in real time, predict potential problems through data analysis, and take timely measures, such as intelligent pump station control and remote fault diagnosis.

[0006] Sponge city construction: Promote the concept of "sponge city", that is, to enhance the city's natural infiltration capacity and rainwater collection and reuse capacity through green infrastructure (such as permeable pavement and rainwater gardens), and reduce surface runoff.

[0007] 2) Sewage treatment.

[0008] Sewage treatment plant upgrades: To meet higher environmental protection standards, many places are upgrading and renovating existing sewage treatment facilities and introducing more advanced treatment processes, such as membrane bioreactors (MBRs) and advanced oxidation processes (AOPs).

[0009] Decentralized treatment: For remote areas or small communities, develop decentralized wastewater treatment solutions, such as integrated wastewater treatment equipment, to reduce transportation costs and improve treatment efficiency.

[0010] Recycled water reuse: Promote the use of sewage after deep treatment as recycled water in green irrigation, industrial cooling and other fields, thereby realizing the recycling of water resources.

[0011] With the continuous changes in needs and the increasing requirements for water storage and drainage response capabilities, the current construction and renovation of urban pipeline networks has become particularly urgent.

[0012] In some solutions, the drain valve requires an external power supply to drive its rotation. If the valve is used for sewage discharge or underwater, it also needs to have strong sealing performance, which places extremely high cost requirements and is not conducive to the construction of large-scale urban water storage, drainage and sewage treatment renovation projects. Utility Model Content

[0013] Based on this, the purpose of this application is to provide a hydraulic flotation valve, which has the advantages of not requiring an external power supply and being low in cost.

[0014] In one aspect of the present application, a hydraulic flotation valve is provided, comprising a butt joint, a cover plate, a hinged member, an abutting member, and an air flotation cover;

[0015] The butt-jointed pipe is placed transversely;

[0016] The bottom of one end of the butt joint tube is hinged to the bottom of the cover plate via the hinge; the hinge is used to open and close the cover plate relative to the butt joint tube;

[0017] The abutment member is fixed to the bottom of the butt-jointed tube and is used to support the cover plate or the air flotation cover;

[0018] The air flotation cover is mounted and fixed on the cover plate;

[0019] The included angle between the cover plate and the end face of the butt pipe is less than 180°;

[0020] The cover plate is rotatably covered on the end surface of the butt-joint pipe.

[0021] The hydraulic flotation valve described in this application has a cover plate that is snapped onto the end of the butt joint to block the flow of water into the butt joint. The cover plate is connected to the butt joint via a hinge, and the hinge is connected to the bottom of the butt joint, so that the cover plate can rotate and open and close relative to the butt joint, with the opening and closing direction rotating downward. A chamber is formed in the flotation hood, and the flotation hood and the cover plate are fixedly snapped together to form a closed space in the chamber. When the water level in the reservoir increases, due to the air in the flotation hood, the water lifts the flotation hood, causing the flotation hood and the cover plate to rotate relative to the butt joint. Finally, the cover plate covers the end of the butt joint, achieving the effect of limiting the flow of water into the butt joint. Due to the presence of an abutment, when the cover plate rotates downward, the cover plate or the flotation hood abuts against the abutment, so that the angle of the cover plate opening relative to the butt joint is limited, thereby facilitating the rotation of the flotation hood when the water lifts it up. The hydraulic flotation valve of the present invention does not require an external power supply and can be closed by relying solely on the buoyancy of the water level. It can also be opened when the water level drops, thereby controlling the amount of water discharged into the drain pipe. The hydraulic flotation valve of the present invention has a simple structure, is easy to manufacture, and has the advantages of low cost and good effect.

[0022] Furthermore, the hinged member is any one of a hinge and an articulated steel structure.

[0023] Furthermore, the abutment member is any one of a vertical rod, an abutment block, an abutment triangle block, and an abutment fork.

[0024] Furthermore, the air flotation cover is fixedly buckled on the cover plate, and the air flotation cover and the cover plate form a cavity.

[0025] Furthermore, the cross-section of the butt joint tube is one of circular, elliptical, square and rectangular;

[0026] The cross-sectional shape of the cover plate is one of circular, elliptical, square and rectangular.

[0027] Furthermore, it also includes an air bag, which is installed in the air flotation cover.

[0028] Furthermore, the cover plate can be opened and closed in a range of 0° to 150° relative to the butt joint.

[0029] Furthermore, the end surface of the butt joint tube that contacts the cover plate is vertically or obliquely arranged;

[0030] The inclination angle of the end face of the butt-jointed pipe is 30° to 90°.

[0031] Furthermore, a rubber ring is included, and the rubber ring is sleeved on the end of the butt joint tube that abuts against the cover plate.

[0032] Furthermore, it also includes a fastener, which is installed on the butt-jointed pipe;

[0033] The fastener is used for fastening the connection between the butt joint pipe and the drain pipe.

[0034] For better understanding and implementation, the present application is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting this application. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0048] See also Figures 1-12 As shown, an exemplary hydraulic flotation valve of the present application includes a butt joint 10, a cover plate 20, a hinge 40, an abutment member 50, and an air flotation cover 30;

[0049] The butt joint pipe 10 is placed horizontally;

[0050] The bottom of one end of the butt joint 10 is hinged to the bottom of the cover plate 20 via the hinge 40 ; the hinge 40 is used to open and close the cover plate 20 relative to the butt joint 10 ;

[0051] The abutment member 50 is fixed to the bottom of the butt joint 10 and is used to support the cover plate 20 or the air flotation cover 30;

[0052] The air flotation cover 30 is mounted and fixed on the cover plate 20;

[0053] The included angle between the cover plate 20 and the end surface of the butt-joint pipe 10 is less than 180°;

[0054] The cover plate 20 is rotatably mounted on the end surface of the butt joint 10 .

[0055] The hydraulic flotation valve described in the present application has a cover plate 20 that is fastened to the end of the butt joint 10 to block the water flow into the butt joint 10. The cover plate 20 is connected to the butt joint 10 via a hinge 40, and the hinge 40 is connected to the bottom of the butt joint 10, so that the cover plate 20 can rotate and open and close relative to the butt joint 10, and the opening and closing direction rotates downward; a chamber is formed in the flotation cover 30, and the flotation cover 30 is fixedly fastened to the cover plate 20, forming a closed space in the chamber. When the water level in the water reservoir rises, due to the air in the flotation cover 30, the water lifts the flotation cover 30, and at the same time causes the flotation cover 30 and the cover plate 20 to rotate relative to the butt joint 10, and finally the cover plate 20 covers the end of the butt joint 10, thereby limiting the water flow into the butt joint 10. Due to the presence of the abutment 50, when the cover plate 20 rotates downward, the cover plate 20 or the air flotation hood 30 abuts against the abutment 50, so that the opening angle of the cover plate 20 relative to the docking pipe 10 is limited, thereby facilitating the rotation of the air flotation hood 30 when the water lifts it up. The hydraulic flotation valve of the present application does not require an external power supply, and can be closed by relying on the buoyancy of the water level. It can also be opened when the water level drops, thereby controlling the amount of water discharged into the drain pipe. The hydraulic flotation valve of the present application has a simple structure, is easy to manufacture, and has the advantages of low cost and good effect.

[0056] In some preferred embodiments, the air flotation hood 30 is cylindrical and has a chamber (not shown) containing a gas, such as air, nitrogen, or a rare gas. The gas in the chamber enables the air flotation hood 30 to float under the buoyancy of water. In this embodiment, the chamber is formed solely by the air flotation hood 30 and is independent of the presence of the cover plate 20. Therefore, the chamber in this embodiment is different from the cavity described in this application.

[0057] In other preferred embodiments, the air flotation cover 30 includes a tube and an end plate. One end of the tube is fastened to the end plate, and the other end is fastened to the cover plate 20. The seal between the end plate and the cover plate 20 forms a chamber within the air flotation cover 30. Furthermore, in this embodiment, the chamber is formed by the air flotation cover 30 and the cover plate 20 together. Therefore, the chamber in this embodiment is also referred to as a cavity as described herein.

[0058] Whether it is a cavity or a chamber, their function is to form a space that can be filled with gas, so that it can float in water and provide buoyancy.

[0059] In some preferred embodiments, the cover plate 20 and the air flotation cover 30 are integrally formed.

[0060] In some preferred embodiments, the cross-sectional area of ​​the cover plate 20 is larger than the cross-sectional area of ​​the air floatation cover 30 .

[0061] In other preferred embodiments, the cross-sectional area of ​​the cover plate 20 is equal to the cross-sectional area of ​​the air flotation cover 30 .

[0062] In some further preferred embodiments, the cross-sectional area of ​​the cover plate 20 is smaller than the cross-sectional area of ​​the air floatation cover 30 .

[0063] In the above embodiments, if the air flotation hood 30 alone can form a chamber, then the purpose of the present application can be achieved regardless of the cross-sectional area of ​​the cover plate 20 and the air flotation hood 30. If the air flotation hood 30 needs to be assembled together with the cover plate 20 to form a chamber (i.e., a cavity), then the cover plate 20 needs to completely cover the through-holes of the air flotation hood 30. Preferably, the cover plate 20 and the air flotation hood 30 have the same shape, and the cross-sectional area of ​​the cover plate 20 is greater than or equal to the cross-sectional area of ​​the air flotation hood 30. For example, the cover plate 20 is circular, the outer contour of the end face of the air flotation hood 30 is also circular, and the circular area of ​​the cover plate 20 is greater than or equal to the outer circular area of ​​the air flotation hood 30.

[0064] In some preferred embodiments, the hinge 40 is any one of a hinge and an articulated steel structure. Hinges come in various forms, including one-stage hinges, two-stage hinges, hydraulic buffer hinges, and touch-activated self-opening hinges. They can also be ordinary one-stage hinges, ordinary two-stage hinges, short-arm hinges, 26-cup miniature hinges, pin hinges, aluminum frame door hinges, special angle hinges, glass hinges, rebound hinges, American hinges, damping hinges, thick door hinges, and the like.

[0065] In some preferred embodiments, the abutment member 50 is any one of a vertical rod, an abutment block, an abutment triangle, and an abutment fork. The function of the abutment member 50 in this application is to limit the rotation angle of the cover plate 20 (or the air flotation cover 30). Therefore, the abutment can be surface contact, point contact, or line contact. These three contact methods are used to abut, thereby preventing the cover plate 20 (or the air flotation cover 30) from rotating too much.

[0066] The excessive rotation angle mentioned here means that the cover plate 20 cannot be rotated to the vertical position. In other words, the maximum rotation angle of the cover plate 20 should be less than 180 degrees, and even 179 degrees is acceptable. If the cover plate 20 is rotated to the vertical downward position, the buoyancy at this time will not be enough to push the air flotation cover 30 upward.

[0067] In some preferred embodiments, the air flotation cover 30 is fixedly buckled on the cover plate 20 , and the air flotation cover 30 and the cover plate 20 form a cavity.

[0068] In some preferred embodiments, the cross-section of the butt joint 10 is one of circular, oval, square, and rectangular;

[0069] The cross-sectional shape of the cover plate 20 is one of circular, elliptical, square and rectangular.

[0070] To ensure shape correspondence, if the butt joint tube 10 is circular, the cover plate 20 is circular; if the butt joint tube 10 is elliptical, the cover plate 20 is elliptical; if the butt joint tube 10 is square, the cover plate 20 is square; if the butt joint tube 10 is rectangular, the cover plate 20 is rectangular.

[0071] In addition, if the cover plate 20 can cover the end surface of the butt joint pipe 10, then the butt joint pipe 10 is circular and the cover plate 20 can be any shape, such as circular, square, oval, or rectangular.

[0072] If the cover plate 20 cannot completely cover the end surface of the butt joint pipe 10 , it is also acceptable as long as it can play a role in preventing water from entering the butt joint pipe 10 to a certain extent.

[0073] Figures 1-9 Shown are the circular cover plate (and circular air flotation cover) and the circular docking tube; Figure 10 Shown are the square cover plate (and square air flotation cover) and square docking tubes.

[0074] The best solution is that the cover plate 20 can completely cover the end surface of the butt-joint pipe 10 .

[0075] In the connection between the butt joint 10 and the cover plate 20 of the present application, a sealing ring may be provided in one preferred embodiment; in another preferred embodiment, no sealing ring is provided. When no sealing ring is provided, a tiny gap may be formed between the butt joint 10 and the cover plate 20 due to processing quality, and this gap may form a small water flow. Even if water flows through the butt joint 10, it does not affect the implementation of the technical solution of the present application. Because a large amount of water flow has been blocked, the water flow through the butt joint 10 will become much smaller, and the purpose of the present application can be achieved. When a sealing ring is provided, the sealing effect between the butt joint 10 and the cover plate 20 is better, and almost no water will flow through the butt joint 10. It is preferable that the sealing ring is provided at the end of the butt joint 10.

[0076] Some preferred embodiments also include an airbag (not shown) mounted within the air flotation dome 30. The air flotation dome 30 itself provides the cavity (or chamber) required for buoyancy, and the airbag also serves to provide the necessary buoyancy. The placement of the airbag within the air flotation dome 30 enhances the airtightness of the structure. Even if the air flotation dome 30 develops a leak, the airbag is still there, providing a double layer of protection.

[0077] In some preferred embodiments, the cover plate 20 can be opened and closed in a range of 0° to 150° relative to the butt joint 10 .

[0078] In other preferred embodiments, the cover plate 20 can be opened and closed in a range of 0° to 90° relative to the butt joint 10 .

[0079] In the present application, the opening and closing range of the cover plate 20 compared to the butt joint 10 refers to the value range of the angle a in the accompanying drawings. The range of this angle a cannot exceed 180°, that is, as described in the above scheme, the angle between the cover plate 20 and the end face of the butt joint 10 is less than 180°; if it exceeds 180°, it is difficult for the buoyancy to make the air flotation cover 30 float, because the rotation angle is too large, and the upward force of the buoyancy causes the air flotation cover 30 to rise in the direction opposite to the target direction, which is not conducive to the realization of the purpose of the present application.

[0080] like Figure 4 As shown, in some preferred embodiments, the end surface of the butt joint 10 that abuts against the cover plate 20 is vertically or obliquely arranged;

[0081] When the end surface of the butt joint pipe 10 is inclined, the inclination angle of the end surface of the butt joint pipe 10 is 30° to 90°.

[0082] In the attached Figure 4 In the state shown in the figure, the end face of the butt tube 10 is inclined relative to the tube wall, so that the cover plate 20 is inclined relative to the end face of the butt tube 10, and the inclination angle c during inclination ranges from 30° to 90°; in some preferred embodiments, the inclination angle c is 60°; in other preferred embodiments, the inclination angle c is 75°. The values ​​of the inclination angle c can be 80°, 85°, 89°, 90°, and so on.

[0083] In some preferred embodiments, a rubber ring 60 is further included. The rubber ring 60 is sleeved on one end of the butt joint pipe 10 that abuts against the cover plate 20 .

[0084] The rubber ring 60 here plays a role of reinforcement and can also play a certain sealing effect for sealing the cover plate 20 and the butt pipe 10.

[0085] In some preferred embodiments, the abutment member 50 can be mounted at either the end or the middle of the bottom surface of the butt joint tube 10. This is sufficient as long as the angle a is less than 180° when abutting the air flotation cover 30. In the embodiment shown in the drawings, the abutment member 50 abuts the end of the bottom surface of the butt joint tube 10.

[0086] In some preferred embodiments, a fastener 70 is further included, and the fastener 70 is installed on the butt joint pipe 10;

[0087] The fastener 70 is used to fasten the butt joint 10 to the drain pipe.

[0088] In the present application, one implementation of the fastener 70 is a bolt, another implementation is a clamp, and yet another implementation is a spring.

[0089] For example, in the embodiment shown in the accompanying drawings, the fastener 70 is a bolt. There are two ways to assemble the bolt: one is to have the bolt head outside the pipe and the butt joint 10 assembled outside the drain pipe; the other is to have the bolt head inside the pipe and the butt joint 10 assembled inside the drain pipe.

[0090] Connecting the butt joint pipe 10 to the drain pipe and clamping and fastening it with a clamp is also a way to implement the technical solution of the present application.

[0091] The implementation method of the spring is similar to the principle of the bolt. The spring is assembled between the butt joint 10 and the drain pipe, and multiple springs are provided, each located at a different angular position.

[0092] In this application, the butt joint 10 is made of steel or plastic, the cover plate 20 is made of steel or plastic, the hinge 40 is made of steel or plastic, the abutment 50 is made of steel or plastic, and the air flotation cover 30 is made of steel or plastic; steel materials include ferroalloy, stainless steel, alloy steel, etc.

[0093] In order to ensure good anti-corrosion performance in a humid environment, the butt joint 10, the cover plate 20, the hinge 40, the abutment 50, and the air flotation cover 30 are respectively made of stainless steel.

[0094] Working principle of the hydraulic flotation valve of this application:

[0095] like Figures 1-12 As shown, and with reference to Figure 11 and Figure 12 In the water reservoir D, the water entering from the discharge main pipe A is stored in the water reservoir D, enters the first water treatment system through the drainage pipe B1, and enters the second water treatment system through the discharge pipe B2.

[0096] Since the first water treatment system has a limited processing load and needs to be shut down in an emergency, if the water reservoir contains sewage, it is difficult to operate the electric valve, and if multiple electric valves are installed, the cost will be very high. The solution of this application can solve this problem well.

[0097] When the water level in the reservoir is lower than the height of the drain pipe B1, the air flotation cover 30 on the butt joint pipe 10 will be in a state of Figure 3 The status shown.

[0098] When the water level in the reservoir gradually rises and gradually becomes higher than the butt joint 10, the air flotation cover 30 rotates relative to the butt joint 10 under the action of buoyancy, and the cover plate 20 is closed relative to the butt joint 10, presenting the following Figure 1 or Figure 2 At this time, the water level continues to rise and is discharged from the discharge pipe B2 and enters the second water treatment system for treatment.

[0099] At the same time, the diameter of the discharge pipe B2 can be larger than the diameter of the drain pipe B1, or the diameters of the two pipes can be equal.

[0100] When the water level in the water reservoir drops and reaches a position lower than the location of the drainage pipe B1 , the cover plate 20 and the air flotation cover 30 are opened relative to the docking pipe 10 .

[0101] When the water level is in the interval between the bottom and top surfaces of the butt joint 10, the cover plate 20 forms a certain angle relative to the end surface of the butt joint 10, namely, angle a. The size of angle a changes with the change of water level until it is fully open or fully closed.

[0102] The principle of the state change of the cover plate 20 and the air flotation cover 30 relative to the butt joint 10 is as follows: Figure 12 As shown, Figure 12 The vertical arrow in the figure indicates the direction of buoyancy, and the horizontal arrow indicates the process after the change.

[0103] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
