Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a single-flow valve with bidirectional controllable function. Background Technology

[0002] A check valve is a one-way throttle valve, which controls the flow rate of fluid by changing the throttling cross section or throttling length. A throttle valve and a check valve connected in parallel can be combined to form a one-way throttle valve. Throttling valves and one-way throttle valves are simple flow control valves. In a fixed displacement pump hydraulic system, a throttle valve and a relief valve can be used together to form three types of throttling speed control systems: an inlet throttling speed control system, a return throttling speed control system, and a bypass throttling speed control system.

[0003] However, existing check valves can only allow fluid to flow in one direction, while fluid in the other direction cannot flow through the check valve. Sometimes it is necessary to allow fluid to flow between the two sides of the check valve, which existing check valves cannot achieve, thus having certain limitations. Therefore, in order to solve this problem, a check valve with bidirectional controllability is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-flow valve with bidirectional controllability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-flow valve with bidirectional controllable function includes a spherical shell, wherein the spherical shell is respectively connected to a first connecting pipe and a second connecting pipe;

[0007] An installation plate is rotatably mounted inside the spherical shell. A sleeve is installed on the side of the installation plate. A guide rod is slidably connected inside the sleeve. A fan-shaped baffle is connected to the end of the guide rod. A spring is installed between the fan-shaped baffle and the sleeve. The guide rod is located in the inner ring of the spring. A rubber sealing gasket is installed on the side of the fan-shaped baffle away from the guide rod.

[0008] Preferably, a mounting shell is installed on the outer wall of the spherical shell, and a servo motor is installed on the top wall of the inner wall of the mounting shell. The output shaft of the servo motor is inserted into the spherical shell and connected to the mounting plate.

[0009] Preferably, a connecting block is installed on the top of the mounting plate, a second rotating shaft is installed on the top of the connecting block, a through hole is opened on the outer wall of the spherical shell and communicates with the spherical shell, a bushing is installed in the through hole, the second rotating shaft is rotatably installed in the bushing, and the end of the second rotating shaft away from the mounting plate is inserted into the mounting shell and connected to the output shaft of the servo motor.

[0010] Preferably, the second rotating shaft is connected to the output shaft of the servo motor via a coupling.

[0011] Preferably, a controller and a power supply are installed inside the mounting housing, and a control panel is installed on the side of the mounting housing. The control panel is electrically connected to the controller, and the power supply is electrically connected to the servo motor and the controller.

[0012] Preferably, the end of the guide rod away from the sleeve is connected to a reinforcing block, which is fixed to the side of the sector baffle near the mounting plate.

[0013] Preferably, a first rotating shaft is installed at the bottom of the mounting plate, and a groove is provided on the inner wall of the spherical shell. A bearing is installed in the groove, and the end of the first rotating shaft away from the mounting plate is installed in the inner ring of the bearing.

[0014] Preferably, both the first connecting pipe and the second connecting pipe are equipped with connecting flanges at their ends.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the fan-shaped baffle rotates to block the connection between the first connecting pipe and the spherical shell and then stops. The flow in the first connecting pipe impacts the fan-shaped baffle, and the impact force of the fluid compresses the spring, causing the fan-shaped baffle to move away from the connection between the first connecting pipe and the spherical shell. This allows the fluid in the first connecting pipe to enter the spherical shell, and the fluid in the spherical shell can then enter the second connecting pipe, while the fluid in the second connecting pipe cannot enter the first connecting pipe. By using a servo motor to rotate the fan-shaped baffle to the connection between the second connecting pipe and the spherical shell, the connection between the second connecting pipe and the spherical shell can be blocked. At this time, the fluid in the second connecting pipe can impact the fan-shaped baffle and enter the spherical shell, and then the fluid in the second connecting pipe can enter the first connecting pipe through the spherical shell, while the fluid in the first connecting pipe cannot enter the second connecting pipe through the spherical shell.

[0017] 2: In this utility model, when it is necessary to connect the first connecting pipe and the second connecting pipe, the servo motor is used to rotate the sector baffle so that it does not block the connection between the first connecting pipe and the spherical shell, nor does it block the connection between the second connecting pipe and the spherical shell. At this time, the first connecting pipe and the second connecting pipe are in a state of mutual connection. This device can enable the traditional single-flow valve to have a bidirectional controllable function, and can be adjusted independently according to actual needs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A single-flow valve with bidirectional controllable function includes a spherical shell 1, and the spherical shell 1 is respectively connected to a first connecting pipe 2 and a second connecting pipe 3;

[0026] An mounting plate 7 is rotatably installed inside the spherical shell 1. A sleeve 10 is installed on the side of the mounting plate 7. A guide rod 13 is slidably connected inside the sleeve 10. A fan-shaped baffle 16 is connected to the end of the guide rod 13. A spring 14 is installed between the fan-shaped baffle 16 and the sleeve 10. The guide rod 13 is located in the inner ring of the spring 14. A rubber sealing gasket 17 is installed on the side of the fan-shaped baffle 16 away from the guide rod 13.

[0027] As a technical optimization of this utility model, a mounting shell 5 is installed on the outer wall of the spherical shell 1, and a servo motor 18 is installed on the inner top wall of the mounting shell 5. The output shaft of the servo motor 18 is inserted into the spherical shell 1 and connected to the mounting plate 7. A connecting block 11 is installed on the top of the mounting plate 7, and a second rotating shaft 12 is installed on the top of the connecting block 11. A through hole communicating with the spherical shell 1 is opened on the outer wall of the spherical shell 1, and a bushing 20 is installed in the through hole. The second rotating shaft 12 is rotatably installed in the bushing 20, and the end of the second rotating shaft 12 away from the mounting plate 7 is inserted into the mounting shell 5 and connected to the servo motor. The output shaft of servo motor 18 is connected; the second rotating shaft 12 is connected to the output shaft of servo motor 18 via coupling 19; a controller 21 and a power supply 22 are installed inside the mounting housing 5, and a control panel 6 is installed on the side of the mounting housing 5. The control panel 6 is electrically connected to the controller 21, and the power supply 22 is electrically connected to servo motor 18 and controller 21; the rotation of the output shaft of servo motor 18 can easily drive the second rotating shaft 12 to rotate, thereby driving the mounting plate 7 to rotate and causing the fan-shaped baffle 16 to rotate; the connecting block 11 can facilitate the connection between the second rotating shaft 12 and the mounting plate 7.

[0028] As a technical optimization of this utility model, a reinforcing block 15 is connected to the end of the guide rod 13 away from the sleeve 10. The reinforcing block 15 is fixed to the side of the fan-shaped baffle 16 near the mounting plate 7. A first rotating shaft 8 is installed at the bottom of the mounting plate 7. A groove is opened on the inner wall of the spherical shell 1, and a bearing 9 is installed in the groove. The end of the first rotating shaft 8 away from the mounting plate 7 is installed in the inner ring of the bearing 9. A connecting flange 4 is installed at the end of the first connecting pipe 2 and the second connecting pipe 3. The reinforcing block 15 can increase the connection strength between the guide rod 13 and the fan-shaped baffle 16. Through the cooperation of the first rotating shaft 8 and the bearing 9, a reverse guide can be provided for the rotation of the mounting plate 7, improving the stability of the mounting plate 7 during rotation. A connecting flange 4 is installed at the end of the first connecting pipe 2 and the second connecting pipe 3, which facilitates the connection of the first connecting pipe 2 and the second connecting pipe 3 to external pipelines.

[0029] In use, when the fluid needs to flow in one direction, i.e., when the fluid in the first connecting pipe 2 needs to flow into the second connecting pipe 3, the control panel 6 transmits a signal to the controller 21. The controller 21 controls the servo motor 18 to start. The output shaft of the servo motor 18 drives the second rotating shaft 12 to rotate. The rotation of the second rotating shaft 12 drives the mounting plate 7 to rotate. The rotation of the mounting plate 7 drives the sleeve 10, guide rod 13, spring 14, and sector-shaped baffle 16 to rotate. When the sector-shaped baffle 16 rotates inside the spherical shell 1, the sector-shaped baffle 16 generates a pushing force with the inner wall of the spherical shell 1, which in turn compresses the spring 14, causing the sector-shaped baffle 16 to rotate. When plate 16 moves away from the inner wall of spherical shell 1, the sector baffle 16 rotates within spherical shell 1 until it stops blocking the connection between the first connecting pipe 2 and spherical shell 1. At this point, the flow in the first connecting pipe 2 impacts the sector baffle 16, and the fluid impact force compresses the spring 14, causing the sector baffle 16 to move away from the connection between the first connecting pipe 2 and spherical shell 1. This allows the fluid in the first connecting pipe 2 to enter spherical shell 1, and the fluid in spherical shell 1 can then enter the second connecting pipe 3, while the fluid in the second connecting pipe 3 cannot enter the first connecting pipe 2.

[0030] When the fluid in the second connecting pipe 3 needs to enter the first connecting pipe 2, the servo motor 18 is used again to rotate the fan-shaped baffle 16 to the connection point between the second connecting pipe 3 and the spherical shell 1. The fan-shaped baffle 16 blocks the connection point between the second connecting pipe 3 and the spherical shell 1. At this time, the fluid in the second connecting pipe 3 can impact the fan-shaped baffle 16 to enter the spherical shell 1, thereby allowing the fluid in the second connecting pipe 3 to enter the first connecting pipe 2 through the spherical shell 1. Meanwhile, the fluid in the first connecting pipe 2 cannot enter the second connecting pipe 3 through the spherical shell 1.

[0031] When it is necessary to connect the first connecting pipe 2 and the second connecting pipe 3, the servo motor 18 is used to rotate the sector baffle 16 so that it does not block the connection between the first connecting pipe 2 and the spherical shell 1, nor does it block the connection between the second connecting pipe 3 and the spherical shell 1. At this time, the first connecting pipe 2 and the second connecting pipe 3 are in a state of mutual connection. This device can enable the traditional single-flow valve to have bidirectional controllability and can be adjusted independently according to actual needs.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
