DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1 to 5 As shown, a pneumatic pipeline valve structure includes a base 1, which is made of a robust and well-sealing metal material and is designed in the shape of a cuboid, which can stably support and accommodate other components of the entire valve system.

[0020] One end of the base 1 is fixedly connected to the pipe 2 by a precision welding process. The pipe 2 is made of corrosion-resistant alloy steel, and its diameter is set according to the actual working conditions to ensure that the fluid can flow smoothly into the valve structure.

[0021] The other end of the base 1 is also firmly welded to a second pipe 3. The second pipe 3 is made of the same material as the first pipe 2, and the connection between the two and the base 1 is specially sealed to effectively prevent fluid leakage.

[0022] The inner wall of the base 1 is slidably connected to the valve 4 through a high-precision machining process.

[0023] The main body of valve 4 is a disc-shaped structure, made of wear-resistant and corrosion-resistant stainless steel. Its surface is finely ground to ensure sealing and smoothness when sliding with the inner wall of base 1. This sliding connection method allows valve 4 to move precisely within base 1, achieving effective control of the fluid passage between pipe 1 2 and pipe 2 3.

[0024] The outer surface of the base 1 is fastened with a mounting block 5 by bolts. The mounting block 5 is made of aluminum alloy, which is lightweight and high-strength, making it convenient to install the cylinder 604 in the designated position in the base 1 and improving the stability of the cylinder 604 during operation.

[0025] The pneumatic assembly 6 located above the base 1 is the power source for the valve's operation. The control valve 601 adopts an advanced solenoid valve structure, composed of high-strength engineering plastics and metal parts. Its housing has good protective performance and can effectively prevent dust and moisture from entering. The control valve 601 is electrically connected to the controller 7 via wires. The controller 7 is an intelligent programmable controller that can accurately control the opening and closing of the control valve 601 according to a preset program or external signal.

[0026] The output end of the control valve 601 is fixedly connected with a flow divider 602, which is made of brass and has a T-shaped structure. This structure can evenly distribute the incoming gas to two directions.

[0027] The flow divider 602 is fixedly connected with two gas inlet pipes 603 inside. The gas inlet pipes 603 are rubber hoses with good flexibility, which can adapt to different installation layouts. The inner wall of the gas inlet pipes 603 is smooth, reducing the resistance of gas flow. The ends of the two gas inlet pipes 603 far away from the flow divider 602 are fixedly connected with the interiors of the cylinders 604, ensuring that the gas can be stably delivered into the cylinders 604.

[0028] The output end of the control valve 601 is also fixedly connected with an exhaust pipe 605, which is also made of rubber hose. The exhaust pipe 605 is used to exhaust the waste gas in the cylinders 604. The end of the exhaust pipe 605 far away from the control valve 601 is fixedly connected with the interior of one of the cylinders 604. The interior of the exhaust pipe 605 is fixedly connected with a flow divider 606, which is made of brass and has a similar structure to the flow divider 602. The flow divider 606 is used to distribute the gas flow of one exhaust pipe 605 to two exhaust pipes 607.

[0029] The exhaust pipes 607 are rubber hoses. The ends of the exhaust pipes 607 far away from the flow divider 606 are fixedly connected with the interiors of the other cylinders 604. This design ensures that the exhaust processes of the two cylinders 604 are synchronized and smooth during the working process, making the action of the valve 4 more stable and reliable.

[0030] The cylinders 604 are made of aluminum alloy, which has the advantages of light weight and good heat dissipation performance. The piston and piston rod assembly inside the cylinders 604 have high precision and strong sealing performance, which can effectively convert the gas pressure into linear motion.

[0031] The output end of the cylinder 604 is fixedly connected with a bearing plate 8 through bolts. The bearing plate 8 is a metal plate structure with sufficient strength and rigidity, which is used to bear and fix the valve 4.

[0032] The outer side of the bearing plate 8 is provided with a limiting assembly 9.

[0033] The L-shaped bearing frame 901 in the limiting assembly 9 is made of stainless steel and has an L-shaped structure. It can be firmly fixed to the outer surface of the bearing plate 8. The inner wall of the L-shaped bearing frame 901 slides with the outer surface of the valve 4, which plays a role in preliminary limiting and guiding the valve 4.

[0034] The inner wall of the L-shaped bearing frame 901 is threadedly connected with two adjusting screws 902, which are made of high-strength alloy steel and have fine threads on the surface. The position of the adjusting screw 902 in the L-shaped bearing frame 901 can be accurately adjusted by rotating the adjusting screw 902.

[0035] One end of the adjusting screw 902 is fixedly connected with a knob 903 made of plastic and having anti-slip patterns on the outer surface, which is convenient for manual operation.

[0036] The other end of the adjusting screw 902 is fixedly connected with a limiting disc 904 which is a circular metal sheet and has an L-shaped bracket 905 rotatably connected to the outer surface of the limiting disc 904. The L-shaped bracket 905 is made of stainless steel and has an L-shaped structure. The inner wall of the L-shaped bracket 905 is in sliding connection with the outer surface of the valve 4.

[0037] When the knob 903 is rotated to drive the adjusting screw 902 to rotate, the limiting disc 904 moves to push the L-shaped bracket 905 to move, thereby quickly releasing or locking the fixed limiting between the bearing plate 8 and the valve 4. The cooperation between the limiting assembly 9, the bearing plate 8 and the valve 4 makes the valve 4 stably fixed on the bearing plate 8 during normal operation to ensure the accurate action of the valve 4, and the limiting can be quickly released when the valve 4 needs to be disassembled, which is convenient for disassembly, maintenance or replacement of the valve 4, and greatly improves the operation convenience and maintenance efficiency of the entire valve structure.

[0038] Working principle: when working, the controller 7 sends an instruction to the control valve 601, the control valve 601 is opened, the gas enters the shunt connector one 602 from the output end, then is evenly distributed to the two gas inlet pipes 603 through the shunt connector one 602, and enters the corresponding cylinder 604, the gas pushes the piston to move in the cylinder 604, the piston drives the bearing plate 8 to move, the bearing plate 8 drives the valve 4 connected thereto to slide on the inner wall of the base 1, so that the valve 4 controls the fluid between the pipeline one 2 and the pipeline two 3, that is, the opening or closing function of the valve 4 is realized, at the same time, the exhaust pipe one 605 and the exhaust pipe two 607 are connected with the exhaust end of the cylinder 604 through the shunt connector two 606, for discharging the exhaust gas in the cylinder 604, when the valve 4 needs to be disassembled, the limiting assembly 9 is operated, the knob 903 on the L-shaped bearing frame 901 is rotated, the knob 903 drives the adjusting screw 902 to rotate, the limiting disc 904 at one end of the adjusting screw 902 moves with the rotation of the screw, and the L-shaped bracket 905 at the other end of the adjusting screw 902 also moves correspondingly, so that the limiting of the bearing plate 8 is released, then the valve 4 needs to be driven by the pneumatic assembly 6 to be completely removed from the base 1, and the operator needs to hold the valve 4 by the palm during the moving process, when the valve 4 is completely removed from the base 1, the valve 4 can automatically move downward to be separated from the clamping limiting of the bearing plate 8, at this time, the valve 4 can be quickly separated from the bearing plate 8, the convenient disassembly, maintenance or replacement of the valve 4 are realized, the whole process is simple to operate, the working efficiency is improved, the cost is reduced, and the downtime of the device is reduced.
