Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic valves, and particularly relates to a multi-way pneumatic valve that can be remotely controlled. Background Art

[0002] The working principle of a pneumatic valve is that a pneumatic control valve consists of an actuator and a regulating mechanism. The actuator is the thrust component of the control valve. It generates a corresponding thrust according to the magnitude of the control signal pressure and pushes the regulating mechanism to act. The valve body is the regulating component of the pneumatic control valve. It directly contacts the regulated medium and regulates the flow rate of the fluid. However, particularly during the operation of current pneumatic valves, the actuator and the regulating mechanism are single, and complex multi-directional control cannot be performed. Especially in multi-way pneumatic valves, the motion state of a single regulating mechanism cannot meet the requirements of a complex conveying process. At the same time, the regulating mechanism can only be controlled at special positions and cannot meet the need for real-time adjustment. Summary of the Invention

[0003] Aiming at the defects in the prior art, the present invention provides a multi-way pneumatic valve that can be remotely controlled.

[0004] A remotely controllable multi-way pneumatic valve, comprising a flow body. A moving channel is formed in the center of the flow body. A valve core structure capable of moving along the moving channel is arranged in the center of the moving channel. The cross-sectional dimension of the valve core structure is the same as that of the moving channel. A pneumatic platform is arranged at the bottom of the valve core structure. A first through port and a second through port are respectively formed in the lower half and the upper half of the right side of the flow body. A third through port and a fourth through port are respectively formed in the lower half and the upper half of the left side of the flow body. A limiting structure is arranged at the top of the flow body. An opening adjusting structure is arranged at the end of the flow body. An elastic part is arranged between the opening adjusting structure and the limiting structure. A control bolt rod capable of sliding and rotating is passed through the centers of the opening adjusting structure and the limiting structure. Wherein, a control channel with the same outer diameter dimension as the control bolt rod is formed in the center of the top surface of the valve core structure. The control bolt rod can penetrate into the control channel. The control channel is connected with a flow channel. After the valve core structure moves along the moving channel, both ends of the flow channel can be simultaneously connected with the first through port and the third through port respectively. A guiding groove is formed on the side surface of the control bolt rod. A guiding convex strip is arranged in the center of the opening adjusting structure. The guiding convex strip is clamped in the guiding groove. The control bolt rod is used to drive the opening adjusting structure to rotate after rotation. The opening adjusting structure is used to make the control channel be separately connected with the second through port or the fourth through port, or be simultaneously connected with the second through port and the fourth through port after rotation. In the whole multi-way pneumatic valve, the first through port feeds materials. The second through port, the third through port and the fourth through port can both feed materials and discharge materials. By the interaction between the pneumatic platform and the air pressure, the valve core structure can move upward. At the same time, by the elastic force of the elastic part, the valve core structure can move downward to reset. During the movement of the valve core structure, the first through port and the third through port are connected with each other. At the same time, based on the arrangement of the control channel and the flow channel in the center of the valve core structure, the first through port can be connected with one of or both the second through port and the third through port, realizing multi-directional conveying. Further, by penetrating the control bolt rod into the control channel in the center of the valve core structure, the flow control channel can be directly blocked, thereby realizing the quick on-off control in the whole multi-directional conveying process. At the same time, the control bolt rod can be remotely controlled by a control module. Wherein, by rotating the control bolt rod and the opening adjusting structure, the flow channel can be blocked, making the first through port and the third through port disconnected. The medium flows into the opening adjusting structure along the guiding groove. Then, by rotating the opening adjusting structure, it can be realized to be respectively connected with the second through port and the fourth through port, or be simultaneously connected with the second through port and the fourth through port. Therefore, the whole multi-way pneumatic valve can meet the complex conveying process and fully realize the remote control of the complex flow movement.

[0005] Preferably, the opening adjustment structure includes: a rotating body disposed between the elastic part and the valve core structure; a connecting passageway opened in the center of the rotating body; and an arc-shaped block protruding from the bottom surface of the rotating body; wherein, a guiding rib is disposed in the connecting passageway and the control bolt rod passes through it. The angle enclosed by the arc-shaped block needs to be greater than 180°, ensuring that it can block more than half of the space at the top of the moving passage. After the rotating body rotates, it drives the bottom arc-shaped block to rotate around the center line of the rotating body, so the position where the arc-shaped block blocks the upper part of the moving passage will be changed, thereby realizing the separate conduction of the second through-port and the fourth through-port.

[0006] Preferably, a limiting ring is provided on the outer wall of the rotating body, and the top surface of the limiting ring contacts the bottom of the elastic part. The elastic part will give a downward thrust to the limiting ring.

[0007] Preferably, a clamping ring groove is opened on the side surface of the valve core structure, and an elastic ring is clamped in the clamping ring groove. Clamping an elastic ring in the clamping ring groove can improve the sealing performance of the entire valve core structure.

[0008] Preferably, there are multiple clamping ring grooves. Multiple clamping ring grooves can further improve the sealing performance of the entire valve core structure.

[0009] Preferably, a positioning ring is provided on the side surface of the valve core structure, a moving groove is opened on the inner wall of the moving passage, and the positioning ring is clamped in the moving groove and can slide along the moving groove. After the positioning ring and the moving groove cooperate, they can limit the moving range of the valve core structure.

[0010] Preferably, a compensation groove is opened on the outer wall of the top of the valve core structure. The compensation groove can guide the flow of the medium entering the opening adjustment structure.

[0011] Preferably, the bottom of the limiting structure is clamped on the outer wall of the flow-through body. Clamping the limiting structure on the outer wall of the flow-through body can, under certain circumstances, remove the limiting structure, thereby realizing the rapid maintenance of the interior of the entire multi-way pneumatic valve.

[0012] Preferably, the control bolt rod is connected to a control terminal, and the control terminal is connected to a remote transmission system. The remote transmission system can realize the remote wireless control of the control terminal and improve the control effect of the control bolt rod.

[0013] Preferably, the elastic part includes a compression spring. The compression spring can generate an outward elastic force after being compressed.

[0014] The beneficial effects of the present invention are reflected in:

[0015] In the present invention, in the entire multi-port pneumatic valve, the first port feeds materials, and the second port, the third port, and the fourth port can either feed or discharge materials. By utilizing the interaction between the pneumatic platform and the air pressure, the valve core structure can move upward. At the same time, by utilizing the elastic force of the elastic part, the valve core structure can move downward to reset. During the movement of the valve core structure, the first port and the third port are connected to each other. At the same time, based on the settings of the central control channel and the flow channel of the valve core structure, the first port can be connected to one or both of the second port and the third port, realizing multi-directional conveying. Further, by inserting a control bolt rod into the central control channel of the valve core structure, the flow control channel can be directly blocked, thereby realizing the quick on-off control of the entire multi-directional conveying process. At the same time, the control bolt rod can be remotely controlled by the control module. Among them, by rotating the control bolt rod and the opening adjustment structure, the flow channel can be blocked, disconnecting the first port from the third port. The medium flows along the guiding groove to the opening adjustment structure, and then by rotating the opening adjustment structure, it can be connected to the second port and the fourth port respectively, or connected to the second port and the fourth port simultaneously. Therefore, the entire multi-port pneumatic valve can meet complex conveying processes and fully realize the remote control of complex flow movement. BRIEF DESCRIPTION OF THE DRAWINGS
