A variable-direction one-way valve

Abstract

The present invention discloses a variable-direction one-way valve, belonging to the technical field of one-way valves, and solves the problem that the liquid flow direction of the existing one-way valve cannot be turned. The variable-direction one-way valve includes a valve body, a controller, a first baffle assembly and a second baffle assembly. By rotating both ends of the controller, the first baffle assembly or the second baffle assembly is inserted into the channel for liquid to flow through on the valve body in a switching manner, and then the rotation of the first movable baffle on the first baffle assembly and the rotation of the second movable baffle on the second baffle assembly are restricted, so that the first movable baffle can only rotate along the side away from the first opening, and the second movable baffle can only rotate along the side away from the second opening. When the first movable baffle is inserted, the liquid in the one-way valve can only flow from the first opening to the second opening, and when the second movable baffle is inserted, the liquid in the one-way valve can only flow from the second opening to the first opening, which can not only maintain the basic function of the one-way valve to control the liquid flow direction, but also switch the liquid flow direction.

Description

Technical Field

[0001] The present invention relates to the technical field of check valves, and particularly to a variable-direction check valve. Background Art

[0002] A check valve is a valve through which fluid can only flow along the inlet, and the medium at the outlet cannot flow back, commonly known as a check valve. A check valve is also called a non-return valve or a reflux valve. It is used in a hydraulic system to prevent the reverse flow of oil, or in a pneumatic system to prevent the reverse flow of compressed air. It can effectively protect the hydraulic pump. When the motor stops moving, it can prevent the residual oil from flowing back and causing the motor to reverse. It can also control the flow rate of the oil in the pump body to prevent the pressure from rising too fast and damaging the equipment.

[0003] The liquid in the check valve can only pass through in one direction, and it may no longer be applicable in some complex working conditions. However, the anti-backflow protection function of the check valve is still required, and many auxiliary devices may be needed to achieve the function. This increases the overall size and weight of the equipment. Summary of the Invention

[0004] The present invention is made in consideration of the foregoing problems, and the object of the invention is to provide a variable-direction check valve with a relatively simple structure that can change the direction of liquid passing through the check valve.

[0005] To achieve the above object, the present invention provides a variable-direction check valve, including:

[0006] A valve body, on which a first opening and a second opening are provided, and a channel for liquid to flow through is provided between the first opening and the second opening;

[0007] A controller, which is rotatably installed on the valve body;

[0008] A first baffle assembly and a second baffle assembly. The first baffle assembly is arranged in the channel near the first opening, and the second baffle assembly is arranged in the channel near the second opening. The first baffle assembly includes a first fixed frame and a first movable baffle rotatably connected to the inside of the first fixed frame. The second baffle assembly includes a second fixed frame and a second movable baffle rotatably connected to the inside of the second fixed frame. The first movable baffle rotates in the direction close to the first opening, the second movable baffle rotates in the direction close to the second opening, or the first movable baffle rotates in the direction away from the first opening, and the second movable baffle rotates in the direction away from the second opening;

[0009] The controller controls the first baffle assembly to be inserted into the channel, the second baffle assembly to be away from the channel, or the first baffle assembly to be away from the channel, and the second baffle assembly to be inserted into the channel.

[0010] For a variable-direction one-way valve as described above, a connecting member is provided on the valve body. A positioning groove is provided at the upper part of the connecting member, and positioning holes are provided on both side walls of the positioning groove. Positioning shafts are provided on both sides of the middle part of the controller, and the positioning shafts are movably clamped in the positioning holes.

[0011] For a variable-direction one-way valve as described above, the first baffle assembly and the second baffle assembly are respectively connected to both ends of the controller. When the two ends of the controller rotate, the first baffle assembly is driven to insert into the channel, the second baffle assembly moves away from the channel, or the first baffle assembly moves away from the channel and the second baffle assembly inserts into the channel.

[0012] For a variable-direction one-way valve as described above, symmetric first cylindrical spherical grooves and second cylindrical spherical grooves are provided at both ends of the controller. A first spherical protrusion is provided at the top of the first fixing frame, and a second spherical protrusion is provided at the top of the second fixing hole. The first spherical protrusion is movably clamped in the first cylindrical spherical groove, and the second spherical protrusion is movably clamped in the second cylindrical spherical groove.

[0013] For a variable-direction one-way valve as described above, a first limiting groove and a second limiting groove are provided on the valve body. The first baffle assembly inserts into or moves away from the channel through the first limiting groove, and the second baffle assembly inserts into or moves away from the channel through the second limiting groove.

[0014] For a variable-direction one-way valve as described above, elastic seals are provided on the inner walls of the first limiting groove and the second limiting groove.

[0015] For a variable-direction one-way valve as described above, a first limiting portion is provided on the first fixing frame for restricting the rotation of the first movable baffle along the direction close to the first opening or the rotation of the first movable baffle along the direction away from the first opening. A second limiting portion is provided on the second fixing frame for restricting the rotation of the second movable baffle along the direction close to the second opening or the rotation of the second movable baffle along the direction away from the second opening.

[0016] For a variable-direction one-way valve as described above, magnetic elements are provided at the bottoms of the first fixing frame and the second fixing frame.

[0017] For a variable-direction one-way valve as described above, two symmetric first mounting holes are provided on the inner side of the upper end of the first fixing frame. First cylindrical protrusions are provided on both sides of the upper end of the first movable baffle, and the first cylindrical protrusions are movably clamped in the first mounting holes. Two symmetric second mounting holes are provided on the inner side of the upper end of the second fixing hole. Second cylindrical protrusions are provided on both sides of the upper end of the second movable baffle, and the second cylindrical protrusions are movably clamped in the second mounting holes.

[0018] The present invention has the following beneficial effects: When one end of the controller is pressed down to control the first baffle assembly to insert into the channel of the valve body until the bottom of the first baffle assembly is completely attached to the bottom of the channel, the first baffle assembly can play a role in restricting the one-way passage of the liquid in the channel. At this time, the first baffle assembly will move upward from the state where the bottom is completely attached to the bottom of the channel and move upward from the second limit groove, and will no longer block the passage of the liquid in the channel. Since the rotation directions of the first movable baffle on the first baffle assembly and the second movable baffle on the second baffle assembly are opposite, it means that when the first baffle assembly or the second baffle assembly is inserted into the channel of the valve body, two one-way valves with different liquid flow directions can be formed in cooperation with the valve body.

[0023] The following are specific embodiments of the present invention and in conjunction with the drawings, the technical solutions of the present invention will be further described, but the invention is not limited to these embodiments.

[0024] As Figures 1 to 4 shown, in this embodiment, a variable-direction one-way valve includes:

[0025] A valve body 100, on which a first opening 110 and a second opening 120 are provided, and a channel 130 for liquid to flow through is provided between the first opening 110 and the second opening 120.

[0026] A controller 200, which is rotatably installed on the valve body 100. The middle part of the controller 200 is rotatably installed on the valve body 100, and both ends of the controller 200 can rotate with the middle part of the controller 200 as a fulcrum. During the rotation of both ends of the controller 200, the first baffle assembly 300 and the second baffle assembly 400 can be driven to move up and down.

[0027] The first baffle assembly 300 and the second baffle assembly 400, the first baffle assembly 300 is arranged in the channel 130 near the first opening 110, and the second baffle assembly 400 is arranged in the channel 130 near the second opening 120, the first baffle assembly 300 includes a first fixed frame 310 and a first movable baffle 320 rotatably connected to the inner side of the first fixed frame 310, the second baffle assembly 400 includes a second fixed frame 410 and a second movable baffle 420 rotatably connected to the inner side of the second fixed frame 410, the first movable baffle 320 rotates in a direction close to the first opening 110, the second movable baffle 420 rotates in a direction close to the second opening 120, or the first movable baffle 320 rotates in a direction away from the first opening 110, the second movable baffle 420 rotates in a direction away from the second opening 120, the rotation direction of the first movable baffle 320 and the second movable baffle 420 represents the liquid flow direction allowed by the one-way valve.

[0028] Further preferably, a first limiting portion 312 is provided on the first fixed frame 310, for limiting the first movable baffle 320 from rotating in a direction close to the first opening 110 or the first movable baffle 320 from rotating in a direction away from the first opening 110, and a second limiting portion 412 is provided on the second fixed frame 410, for limiting the second movable baffle 420 from rotating in a direction close to the second opening 120 or the second movable baffle 420 from rotating in a direction away from the second opening 120.

[0029] In this embodiment, the first limiting portion 312 and the second limiting portion 412 are both protrusions on the two fixed frames, which are used to abut against one side of the first movable baffle 320 and the second movable baffle 420 to prevent them from rotating toward that side. Therefore, they also have the basic function of a one-way valve. The first limiting portion 312 set on the first fixed frame 310 limits the first movable baffle 320 to rotate only in the direction away from the first opening 110, and the second limiting portion 412 set on the second fixed frame 410 limits the second movable baffle 420 to rotate only in the direction away from the second opening 120.

[0030] The controller 200 controls the first baffle assembly 300 to be inserted into the channel 130 and the second baffle assembly 400 to be away from the channel 130 , or the first baffle assembly 300 to be away from the channel 130 and the second baffle assembly 400 to be inserted into the channel 130 .

[0031] The controller 200 is similar to a seesaw structure. When one end of the controller 200 is pressed down, the other end moves upward, thereby simultaneously controlling the first baffle assembly 300 and the second baffle assembly 400 to move up and down in opposite directions. The bottom of only one baffle assembly can be controlled to fit the bottom of the channel 130.

[0032] Preferably, in the embodiment, since the first movable baffle 320 rotates in a direction away from the first opening 110 and the second movable baffle 420 rotates in a direction away from the second opening 120, when the first movable baffle 320 is inserted, the liquid flowing through the valve body 100 can only flow from the direction of the first opening 110 to the direction of the second opening 120. When the second movable baffle 420 is inserted into the channel 130, the liquid flowing through the valve body 100 can only flow from the direction of the second opening 120 to the direction of the first opening 110.

[0033] Preferably, in this embodiment, whether the first baffle assembly 300 or the second baffle assembly 400 mentioned above is inserted into the channel 130, it means that one of the baffle assemblies moves downward, the bottom of the baffle assembly fits with the bottom of the channel 130, and the side wall of the baffle assembly also fits tightly with the side wall of the channel 130. When the first baffle assembly 300 or the second baffle assembly 400 mentioned above moves away from the channel 130, it means that one of the baffle assemblies moves upward, the bottom of the baffle assembly is separated from the bottom of the channel 130, and then the liquid can flow through the channel 130 below the bottom of the baffle assembly. The baffle assembly cannot affect the flow direction of the liquid, but the baffle assembly does not need to be completely separated from the channel 130.

[0034] Specifically, a connecting member 140 is provided on the valve body 100. A positioning groove 141 is provided on the upper part of the connecting member 140, and positioning holes 142 are provided on both side walls of the positioning groove 141. Positioning shafts 210 are provided on both sides of the middle part of the controller 200, and the positioning shafts 210 are movably clamped in the positioning holes 142. Then the middle part of the controller 200 is directly rotatably connected to the valve body 100 through the positioning shafts 210, which facilitates the rotation of the controller 200.

[0035] The first baffle assembly 300 and the second baffle assembly 400 are respectively connected to both ends of the controller 200. The rotation of both ends of the controller 200 drives the first baffle assembly 300 to be inserted into the channel 130, the second baffle assembly 400 to move away from the channel 130, or the first baffle assembly 300 to move away from the channel 130 and the second baffle assembly 400 to be inserted into the channel 130.

[0036] A symmetrical first cylindrical spherical groove 220 and a second cylindrical spherical groove 230 are provided at both ends of the controller 200, a first spherical protrusion 311 is provided on the top of the first fixed frame 310, and a second spherical protrusion 411 is provided on the top of the second fixing hole. The first spherical protrusion 311 is movably clamped in the first cylindrical spherical groove 220, and the second spherical protrusion 411 is movably clamped in the second cylindrical spherical groove 230. The first spherical protrusion 311 is restricted in the first cylindrical spherical groove 220 and can only slide in the first cylindrical spherical groove 220 and cannot be separated from the first cylindrical spherical groove 220. The first spherical protrusion 311 can rotate with a small amplitude when in the first cylindrical spherical groove 220, which can ensure that the first baffle assembly 300 follows the movement of the controller 200 and can always maintain a vertical state. The movement principle of the second baffle assembly 400 is the same.

[0037] A first limiting groove 150 and a second limiting groove 160 are provided on the valve body 100. The first baffle assembly 300 is inserted into or away from the channel 130 through the first limiting groove 150, and the second baffle assembly 400 is inserted into or away from the channel 130 through the second limiting groove 160. The first limiting groove 150 limits the first baffle assembly 300 so that it can only move up and down along the opening direction of the first limiting groove 150, and cooperates with the first cylindrical spherical groove 220 to determine the movement direction of the first baffle assembly 300. Similarly, the second limiting groove 160 also limits the second baffle assembly 400 so that it can only move up and down along the opening direction of the second limiting groove 160.

[0038] Preferably, elastic seals are provided on the inner walls of the first limiting groove 150 and the second limiting groove 160, so that there is no gap between the first baffle assembly 300 and the inner wall of the first limiting groove 150, and the sealing effect is good, preventing liquid from leaking from the first limiting groove 150. Similarly, the elastic seal provided on the second limiting groove 160 can also prevent liquid from leaking from the second limiting groove 160.

[0039] Magnetic elements are provided at the bottom of the first fixing frame 310 and the second fixing frame 410. When the bottom of the first fixing frame 310 or the second fixing frame 410 is connected to the bottom of the channel 130, the bottom of the first fixing frame 310 or the second fixing frame 410 is tightly fitted with the bottom of the channel 130 through the magnetic elements, thereby avoiding the backflow effect through the gap between the bottom of the first fixing frame 310 or the second fixing frame 410 and the bottom of the channel 130. At the same time, it can also prevent the controller 200 from moving around. When no external force is applied to the controller 200, one end thereof is maintained in a lower horizontal position by the adsorption effect of the magnetic element.

[0040] On the inner side of the upper end of the first fixed frame 310, there are two symmetrically arranged first mounting holes. On both sides of the upper end of the first movable baffle 320, there are first cylindrical protrusions 321. The first cylindrical protrusions 321 are movably clamped in the first mounting holes. On the inner side of the upper end of the second fixed hole, there are two symmetrically arranged second mounting holes. On both sides of the upper end of the second movable baffle 420, there are second cylindrical protrusions 421. The second cylindrical protrusions 421 are movably clamped in the second mounting holes. Through the cooperation of the mounting holes and the cylindrical protrusions, the movable baffle can be rotatably connected to the inner side of the fixed frame. Of course, other rotatable connection methods can also be used, including mounting methods similar to hinged ones, which also fall within the protection scope of this application.

[0041] A variable-direction one-way valve provided by the present invention includes a valve body, a controller, a first baffle assembly, and a second baffle assembly. By rotating both ends of the controller, one of the first baffle assembly or the second baffle assembly can be switched and inserted into the channel for liquid flow on the valve body, and then the rotation directions of the first movable baffle on the first baffle assembly and the second movable baffle on the second baffle assembly are restricted, so that the first movable baffle can only rotate along the side away from the first opening, and the second movable baffle can only rotate along the side away from the second opening. When the first movable baffle is inserted, the liquid in the one-way valve can only flow from the first opening to the second opening. When the second movable baffle is inserted, the liquid in the one-way valve can only flow from the second opening to the first opening. It can not only maintain the basic function of the one-way valve to control the liquid flow direction, but also switch the liquid flow direction.

[0042] The technical solution of the present invention has been elaborated in detail above in combination with the accompanying drawings. The described embodiments are used to help understand the idea of the present invention. The specific embodiments described herein are only examples of the spirit of the present invention. Those skilled in the technical field to which the invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
