Description

Technical Field

[0001] This utility model belongs to the field of valve platform technology, specifically relating to a pneumatic valve platform. Background Technology

[0002] A pneumatic valve console is a device used to control the flow of gas in a pneumatic system. Its working principle is based on pneumatic transmission; it controls pneumatic actuators, such as cylinders and pneumatic motors, by controlling the flow of compressed air. When the control element receives a control signal, it changes the position of its internal valve core, thereby controlling the on / off state and direction of compressed air flow. Modern pneumatic valve consoles have relatively simple structures, making it difficult to control multiple pneumatic actuators. This results in large, bulky equipment with multiple actuators, requiring a significant floor space. Summary of the Invention

[0011] Furthermore, the main pneumatic pipe is connected to the distribution pipe, and one end of each of the pneumatic branch pipes is connected to the distribution pipe.

[0012] Furthermore, the gas distribution pipe is connected to several gas branch pipe sections, and each gas branch pipe section is connected to a pipeline connector. One end of the pneumatic branch pipe is connected to the gas distribution pipe through the pipeline connector.

[0013] Furthermore, the diameters of the pneumatic branch pipes are different, and the diameters of the pneumatic branch pipes correspond to the pipe joints.

[0014] Furthermore, there are eight gas branch pipe sections, which are connected to eight pneumatic branch pipes, and the pneumatic branch pipes are DN25, DN32, DN40 or DN50 pipes.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] See appendix Figure 1-3A pneumatic valve platform includes a pneumatic main pipe 1 and several pneumatic branch pipes 2. The pneumatic main pipe 1 and several pneumatic branch pipes 2 are fixed on a bracket 3. A pair of main pipe inlet flanges 4 are provided at the inlet of the pneumatic main pipe 1. One end of several pneumatic branch pipes 2 is connected to the pneumatic main pipe 1, and the other end of several pneumatic branch pipes 2 is respectively connected to a pair of branch pipe outlet flanges 5. A pneumatic control butterfly valve 6 is provided on the pneumatic control butterfly valve 1. A two-position five-way solenoid valve 7 is provided on the pneumatic control butterfly valve 6. The pneumatic control butterfly valve 6 is controlled by the two-position five-way solenoid valve 7. The pneumatic control butterfly valve 6 is connected to the pneumatic main pipe 1 through a butterfly valve flange 8. A ball valve 9, an air filter 10 and an air pressure reducing valve 11 are provided in sequence on each pneumatic branch pipe 2. The pipe diameters of several pneumatic branch pipes 2 can be set to be the same or different, depending on the design of the pipe port of the pneumatic actuator.

[0022] Based on the above technical solution, the two-position five-way solenoid valve 7 has two positions (open and closed) and five air ports. One port connects to the air source, the other two ports connect to the two chambers of the cylinder of the pneumatic butterfly valve 6 respectively, and the remaining two ports are exhaust ports. When the solenoid valve is energized, the valve core actuates, and compressed air from the air source enters one chamber of the pneumatic butterfly valve cylinder through the solenoid valve, pushing the piston to move, thereby rotating the butterfly valve shaft and opening or closing the butterfly valve; simultaneously, air in the other chamber of the cylinder is discharged through the exhaust port of the solenoid valve. When the solenoid valve is de-energized, the valve core returns to its initial position, the compressed air passage changes, and the butterfly valve returns to the opposite state. The air inlet of the pneumatic main pipe is controlled by the pneumatic butterfly valve. The pneumatic inlet and outlet have paired flanges (main pipe inlet flange 4 and branch pipe outlet flange 5, which are bolted together and sealed). Each pneumatic branch pipe is required to undergo an airtightness test before leaving the factory, with a pressure holding time of not less than 5 minutes.

[0023] Furthermore, a terminal box 12 is provided on the valve platform, and electrical components are wired to the terminal box 12. The voltage of the pressure switch solenoid valve is DC24V, and the wiring method of the electrical components is designed according to existing technology.

[0024] Furthermore, the pneumatic main pipe 1 is connected to the air distribution pipe 13, and several air distribution branch pipe sections 14 are connected to the air distribution pipe 13. Each air distribution branch pipe section 14 is connected to a pipeline connector 15. One end of the pneumatic branch pipe 2 is connected to the air distribution pipe 13 through the pipeline connector 15, and the diameter of the pneumatic branch pipe 2 corresponds to that of the pipeline connector 15.

[0025] In the accompanying drawings of this embodiment, there are eight gas branch pipe sections 14, which are connected to eight pneumatic branch pipes. The pneumatic branch pipes are DN25, DN32, DN40, or DN50 pipes. Specifically, the gas branch pipe is connected to three DN50 pneumatic branch pipes, two DN40 pneumatic branch pipes, two DN32 pneumatic branch pipes, and one DN25 pneumatic branch pipe.

[0026] The air inlet of the pneumatic valve station is controlled by a pneumatic butterfly valve 6, and the air is distributed to each pneumatic branch pipe 2 through the distribution pipe 13. Each pneumatic branch pipe 2 is equipped with a ball valve 9, an air filter 10, and an air pressure reducing valve 11. One pneumatic valve station can control multiple pneumatic components, saving costs and reducing floor space. The ball valve 9 controls the opening and closing of the pneumatic branch pipe 2, the air filter 10 filters the compressed air in the pneumatic branch pipe 2, and the air pressure reducing valve 11 regulates and controls the pressure of the compressed air in the pneumatic branch pipe 2. The ball valve 9, air filter 10, and air pressure reducing valve 11 are commercially available brands, and their installation dimensions correspond to the diameter of the pneumatic branch pipes. For example, in this embodiment, the pneumatic butterfly valve 6 is YQZF-80F-2P3 Shanghai Dujie Valve; the two-position two-way solenoid valve 7 is 2W500-50 DC24V, manufactured by Zhejiang Renhe Pneumatic Co., Ltd.; the ball valve 9 is SD1 1 / 2, manufactured by Shenchi Pneumatic; the air filter 10 is QSL-40×60, manufactured by Ningbo Keton Automation Industry Co., Ltd.; and the air pressure reducing valve 11 is QTY-40, manufactured by Ningbo Keton Automation Industry Co., Ltd.
