Description

Technical Field

[0001] The utility model relates to the technical field of bypass valves, in particular to a pneumatic bypass valve with dual-channel synchronous control. Background Art

[0002] A dual-channel bypass valve is a common valve type that features two channels that can connect two pipes or fluid paths simultaneously. This valve is typically used to control the flow or pressure of a fluid. The basic working principle of a dual-channel bypass valve is that when the valve is closed, both channels are blocked, preventing fluid from passing through. When the valve is open, both channels are open, allowing fluid to flow freely through the valve.

[0003] A search revealed a Chinese patent with publication number CN214534710U, which discloses a pneumatic bypass valve. The patent describes a technical solution in which a movable plate and a reserved cavity are provided within a pipe body. When the temperature drops and the water within the valve body begins to freeze, the increased volume of the movable plate pushes the movable plate toward the fixed plate, causing it to slide within the pipe body. Simultaneously, the space in the reserved cavity shrinks, and the freezing water enters the pipe body. This leaves sufficient space within the valve body to ensure that the increased volume of the frozen water does not cause the valve body to crack. This reduces the likelihood of the bypass valve being damaged by freezing, making it more suitable for use in cold weather and improving the practicality of the bypass valve.

[0004] In this solution, although the bypass valve is effectively prevented from being frozen, when the device is connected to the double-way pipe, two controllers for controlling the pipes need to be set up, which will cause asynchrony when the water is passed, resulting in the problem of different flow control of the dual output channels. In order to solve this technical problem, the utility model proposes a pneumatic bypass valve with dual-channel synchronous control. Utility Model Content

In order to solve this technical problem, the utility model proposes a pneumatic bypass valve with dual-channel synchronous control.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dual-channel synchronously controlled pneumatic bypass valve, comprising a bypass valve body, the top of the bypass valve body is fixedly connected to an outer shell, the upper part of the inner shell is fixedly connected to an inner plate, the inner plate is rotatably connected to a rotating sleeve, and the inner part of the rotating sleeve is fixedly connected to a threaded rod, the outer wall of the bottom end of the threaded rod is threadedly connected to a connecting block, both sides of the connecting block are fixedly connected to a limiting block 1, and the inside of the limiting block 1 on both sides is rotatably connected to a rotating rod, the other ends of the rotating rods on both sides are rotatably connected to a limiting block 2, and the outer walls of the limiting block 2 on both sides are fixedly connected to a water baffle, the inner walls of the rotating rods on both sides are fixedly connected to fixed columns, and a spring is fixedly connected between the fixed columns on both sides.

[0009] Preferably, a water outlet pipe 1 is provided on one side of the bypass valve body, and a water outlet pipe 2 is provided on the other side of the bypass valve body. At the same time, water baffles on both sides correspond to the water outlet pipe 1 and the water outlet pipe 2 respectively, and the water baffles are slidably connected to the bypass valve body.

[0014] (3) Beneficial effects

[0015] The utility model provides a pneumatic bypass valve with dual-channel synchronous control. It has the following beneficial effects:

[0016] (1) Turning the handle drives the threaded rod to rotate and causes the connecting block to move upward. The rise of the connecting block drives the rotating rods on the limit blocks 1 at both ends to move upward together. The bottom end of the rotating rod shrinks inward due to the limitation of the limit column on the support rod. The shrinkage of the bottom end of the rotating rod causes the water baffles on both sides to move toward the middle and compress the spring fixed on the fixed column. This action opens the through holes on the outlet pipe 1 and the outlet pipe 2, allowing the water to flow smoothly to the required outlet. When the outlet pipe 1 and the outlet pipe 2 need to be closed, turning the handle in the opposite direction will cause the threaded rod to move downward, and the connecting block will move downward accordingly. The rebound force of the spring will bounce the rotating rod to both sides, and the water baffles will block the outlets of the outlet pipe 1 and the outlet pipe 2 on both sides at the same time. This design realizes the dual-channel synchronous switching of the bypass valve body through precise mechanical coordination and automatic control, solves the flow control and switching problems of the dual output channels in the water pipe system, and ensures the efficiency and stability of the system operation.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] Embodiment 1: A pneumatic bypass valve with dual-channel synchronous control, including a bypass valve body 1, a shell 5 is fixedly connected to the top of the bypass valve body 1, an inner plate 6 is fixedly connected to the upper part of the shell 5, a rotating sleeve 7 is rotatably connected to the inner part of the inner plate 6, and a threaded rod 8 is fixedly connected to the inner part of the rotating sleeve 7, and a connecting block 10 is threadedly connected to the outer wall of the bottom end of the threaded rod 8, and both sides of the connecting block 10 are fixedly connected to a limit block 13, and both sides of the limit block 13 are rotatably connected to the inside of the rotating rod 14, and the other ends of the rotating rods 14 on both sides are rotatably connected to the limit block 2 15, and the outer walls of the limit blocks 2 15 on both sides are fixedly connected to water baffles 16, and the inner walls of the rotating rods 14 on both sides are fixedly connected to fixed columns 17, and a spring 18 is fixedly connected between the fixed columns 17 on both sides, and a water outlet pipe 3 is provided on one side of the bypass valve body 1. A water outlet pipe 2 4 is provided on the other side of the bypass valve body 1, and water baffles 16 on both sides correspond to the water outlet pipe 1 3 and the water outlet pipe 2 4 respectively, and the water baffle 16 is slidably connected to the bypass valve body 1, and a pair of slide grooves 11 are provided on the inner side wall of the outer shell 5. The other two sides of the connecting block 10 are fixedly connected to the limiting plates 12, and the limiting plates 12 correspond to the slide grooves 11, and the limiting plates 12 are slidably connected in the slide grooves 11. Two pairs of support rods 19 are fixedly connected to the inside of the bypass valve body 1, and the other end of the support rod 19 is rotatably connected to the limiting column 20, and the limiting column 20 is located obliquely above the rotating rod 14. The rotating rods 14 on both sides are located between the limiting columns 20 on both sides. At the same time, the rotating rod 14 is slidably connected to the outer shell 5 and the bypass valve body 1, and the top outer wall of the threaded rod 8 is fixedly connected to the handle 9. The outside of the bypass valve body 1 is provided with a water inlet pipe 2.

[0025] Connect the drain pipe to one end of the water inlet pipe 2. When the handle 9 is turned, it drives the threaded rod 8 to rotate. The threaded rod 8 is restrained in a specific position by the limiting sleeve 7 on the inner plate 6. The rotation of the threaded rod 8 causes the connecting block 10 to move upward. During this movement, the limiting plate 12 on the chute 11 ensures that the movement direction of the connecting block 10 remains stable. The rise of the connecting block 10 causes the rotating rod 14 on the limiting block 13 at both ends to move upward. As the rotating rod 14 rises, it is restrained by the limiting column 20 on the support rod 19. The bottom end is forced inward and hinged at both ends to prevent it from getting stuck. When the bottom end of the rotating rod 14 retracts, it drives the water baffles 16 on both sides to move toward the center, compressing the spring 18 fixed to the fixing column 17. The movement of the water baffles 16 simultaneously opens the through-holes in the outlet pipe 1 3 and the outlet pipe 2 4, allowing water to flow synchronously to the outlet pipes 1 3 and 2 4. Because both sides of the rotating rod 14 move synchronously, their coordinated operation achieves dual-channel synchronous control of the bypass valve body 1. To close outlet pipe 1 3 and outlet pipe 2 4, simply rotate the handle 9 in the opposite direction. This causes the threaded rod 8 to move downward, which in turn causes the connecting block 10 to move downward. At this point, the rebound force of the spring 18 causes the rotating rod 14 to spring open to both sides. Simultaneously, the water baffle 16 simultaneously blocks the water outlets of both outlet pipes 1 3 and 2 4. Through the coordinated operation of these operations, efficient operation and control of the valve is achieved.

[0026] Working principle: when the staff uses the device, they first connect the drain pipe to one end of the water inlet pipe 2, and then turn the handle 9. Under the action of the handle 9, the threaded rod 8 is driven to rotate, and the threaded rod 8 is limited on the inner plate 6 by the rotating sleeve 7. When the threaded rod 8 rotates, it will drive the connecting block 10 to move upward. When the connecting block 10 moves, it is limited in the slide groove 11 by the limiting plate 12 to ensure that the moving direction of the connecting block 10 remains consistent. When the connecting block 10 moves upward, it will drive the rotating rod 14 on the limiting blocks 13 at both ends to move upward. When the rotating rod 14 moves, it is limited by the limiting column 20 on the support rod 19, so that the bottom end of the rotating rod 14 can only retract inward. At the same time, the two ends of the rotating rod 14 are hinged respectively, and there will be no jamming. The bottom end of the rotating rod 14 retracts first When the water baffles 16 on both sides move toward the middle, the springs 18 on the fixed columns 17 are squeezed. After the water baffles 16 move, the through holes of the water outlet pipes 1 3 and 2 4 on both sides are opened, and the water will flow synchronously toward the directions of the water outlet pipes 1 3 and 2 4. Because the rotating rods 14 on both sides move upward synchronously, the cooperation between them realizes the effect of dual-channel synchronous control of the bypass valve body 1. When it is necessary to close the water outlet pipes 1 3 and 2 4, the handle 9 is rotated in the opposite direction to drive the threaded rod 8 to rotate, and drive the connecting block 10 to move downward. At this time, the rotating rod 14 will be bounced to both sides by the resilience of the springs 18, so that the water baffles 16 simultaneously block the water outlets of the water outlet pipes 1 3 and 2 4 on both sides. Through the cooperation between them, work efficiency is achieved.
