Description

Technical Field

[0001] This utility model relates to the field of pneumatic valve technology, and in particular to a dual-channel high-thrust pneumatic piston valve. Background Technology

[0002] Valves, as core components of fluid control systems, are widely used in petrochemical, energy and power, water conservancy projects, and aerospace fields. Their performance directly affects the safety, stability, and energy efficiency of the entire system. Traditional valves mostly adopt a single-channel structure, achieving opening and closing functions through mechanical transmission or electromagnetic drive.

[0003] Currently, dual-channel valve designs often employ parallel independent actuators or rotary valve plate structures. While these can achieve multi-channel control, they suffer from drawbacks such as large size, poor synchronization, and high energy consumption. For example, a scheme using two cylinders to drive two valve plates can independently control each channel, but it requires two pneumatic systems, leading to structural redundancy, increased costs, and complex control logic. While rotary valve plate structures simplify the drive mechanism, they struggle to achieve rapid opening and closing and reliable sealing under high pressure differential conditions.

[0004] Therefore, in order to address the above problems, the applicant needs to design a dual-channel high-thrust pneumatic piston valve to solve the problem. Utility Model Content

[0005] This application provides a dual-channel high-thrust pneumatic piston valve, including a support shell, with a connecting pipe fixedly disposed below the support shell. An X-axis pipe and a Y-axis pipe are fixedly connected to the connecting pipe, and the X-axis pipe and Y-axis pipe are respectively connected to external pipes. A connecting section is disposed inside the support shell, and a telescopic rod is fixedly disposed on the connecting section. One end of the telescopic rod, away from the connecting section, passes through the support shell and is fitted with a cylinder. A piston mechanism is fixedly disposed at the end of the connecting section away from the telescopic rod. The piston mechanism is used to open or close the X-axis pipe or the Y-axis pipe. The piston mechanism includes a connecting plate fixedly connected to the connecting section, and a blocking component for opening or closing the Y-axis pipe and an X-axis blocking plate for opening or closing the X-axis pipe are fixedly disposed on the connecting plate.

[0006] Preferably, the barrier component includes a Y-axis barrier plate fixedly connected to the connecting plate, and a movable plate is slidably disposed on the Y-axis barrier plate, which enhances the sealing adaptability and reliability of the valve when closed.

[0007] Preferably, a guide bar is fixedly provided on the Y-axis barrier plate, and the guide bar is slidably connected to the movable plate. The guide bar ensures the stability and precise guidance of the movable plate during its movement.

[0008] Preferably, a fixing block is fixedly installed on the Y-axis barrier plate, and a buffer spring is fixedly installed on the fixing block. A support block is fixedly installed at the end of the buffer spring away from the fixing block, and the support block is fixedly connected to the movable plate. The buffer spring can effectively absorb the impact force when closing, improve the sealing life and operation stability.

[0009] Preferably, a sealing strip is fixedly provided on the side of the movable plate near the bottom of the connecting pipe, and the sealing strip is made of rubber. The sealing strip further improves the sealing performance of the valve and prevents fluid leakage.

[0010] Preferably, a connector is fixedly provided on the support shell, and a support frame is fixedly provided on the connector.

[0012] Preferably, the Y-axis barrier plate and the movable plate are made of stainless steel, and the contact surface between the movable plate and the Y-axis barrier plate is provided with a wear-resistant coating. The wear-resistant coating reduces wear between the movable plate and the Y-axis barrier plate and extends service life.

[0013] This utility model provides a dual-channel high-thrust pneumatic piston valve, which, compared with the prior art: This dual-channel high-thrust pneumatic piston valve achieves efficient synchronous control of both channels through a single cylinder-driven linkage piston mechanism. This greatly simplifies the structure and control system, reduces manufacturing costs and energy consumption.

Detailed Implementation

[0017] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0018] Please refer to Figure 1 and Figure 2 This utility model provides a dual-channel high-thrust pneumatic piston valve, including a support shell 1, and a connecting pipe 10 is fixedly installed below the support shell 1. An X-axis pipe 11 and a Y-axis pipe 110 are fixedly connected to the connecting pipe 10, and the X-axis pipe 11 and the Y-axis pipe 110 are respectively connected to external pipes. A connecting section 16 is provided on the inner side of the support shell 1, and a telescopic rod 15 is fixedly installed on the connecting section 16. The end of the telescopic rod 15 away from the connecting section 16 passes through the support shell 1 and is provided with a cylinder 14. A piston mechanism 2 is fixedly installed on the end of the connecting section 16 away from the telescopic rod 15, and the piston mechanism 2 is used to open or close the X-axis pipe 11 or the Y-axis pipe 110.

[0019] like Figure 3 , Figure 4 and Figure 5 As shown, the piston mechanism 2 includes a connecting plate 20 fixedly connected to the connecting section 16. The connecting plate 20 is fixedly provided with a blocking component for opening or closing the Y-axis pipe 110 and an X-axis blocking plate 23 for opening or closing the X-axis pipe 11. The cylinder 14 drives the connecting plate 20 to move as a whole through the telescopic rod 15, so that the X-axis blocking plate 23 fixed thereon and the Y-axis blocking plate 21 with the movable plate 22 can rise and fall synchronously, so as to open or close the X-axis and Y-axis pipes respectively. The movable plate 22 can slide relative to the Y-axis blocking plate 21 and is in close contact with the sealing surface under the action of the buffer spring 26.

[0020] The barrier component includes a Y-axis barrier plate 21 fixedly connected to the connecting plate 20, and a movable plate 22 slidably disposed on the Y-axis barrier plate 21. A guide strip 24 is fixedly disposed on the Y-axis barrier plate 21 and slidably connected to the movable plate 22. A fixing block 25 is fixedly disposed on the Y-axis barrier plate 21, and a buffer spring 26 is fixedly disposed on the fixing block 25. A support block 27 is fixedly disposed at the end of the buffer spring 26 away from the fixing block 25 and is fixedly connected to the movable plate 22. A sealing strip is fixedly disposed on the side of the movable plate 22 near the bottom surface 10 of the connecting pipe, and the sealing strip is made of rubber. The guide strip 24 provides precise guidance for the up and down movement of the movable plate 22 to prevent it from deviating. When the valve is closed, the movable plate 22 contacts the valve seat first, and the buffer spring 26 is compressed to absorb the impact force and provide continuous sealing pressure. The rubber sealing strip is used to fill the micro gaps.

[0021] like Figure 1 As shown, a connector 12 is fixedly installed on the support shell 1, and a support frame 13 is fixedly installed on the connector 12. The support frame 13 is fixedly connected to the cylinder 14. The support frame 13 is firmly installed on the support shell 1 through the connector 12, providing a rigid mounting base for the cylinder 14. The robust support structure ensures that the cylinder 14 remains stable during operation, effectively dispersing the reaction force of the working power, and improving the rigidity and reliability of the entire drive system.

[0022] The X-axis baffle 23 is made of stainless steel, as are the Y-axis baffle 21 and the movable plate 22. The contact surface between the movable plate 22 and the Y-axis baffle 21 is coated with a wear-resistant coating. The stainless steel provides excellent corrosion resistance and structural strength, extending the service life of the valve under harsh conditions. The wear-resistant coating reduces wear between moving parts, further ensuring the stability and reliability of the valve's long-term operation.

[0023] In summary, when using this dual-channel high-thrust pneumatic piston valve, the cylinder 14 drives the telescopic rod 15 and the connecting section 16 fixed thereto to move linearly, thereby driving the entire piston mechanism 2 to rise and fall synchronously. The X-axis baffle plate 23 on the connecting plate 20 moves directly with the connecting plate 20 to open or close the X-axis pipe 11. In the baffle component used to control the Y-axis pipe 110, the Y-axis baffle plate 21 moves with the connecting plate 20 and drives the movable plate 22 on it to slide along the guide bar 24. When the valve is closed, the sealing strip at the bottom of the movable plate 22 contacts the valve seat first, and the buffer spring 26 is compressed to absorb the impact force and provide a continuous sealing pressure. Finally, the opening, closing and sealing of the dual channels are controlled efficiently, synchronously and reliably using a single drive source.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
