Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, specifically to a pneumatic ball valve assembly. Background Technology

[0002] In the field of industrial automation, pneumatic ball valves, as key components for controlling airflow, are widely used in the pneumatic control systems of various working equipment. Traditional pneumatic ball valve control typically relies directly on the air supply from the working equipment. When there are pressure fluctuations, unstable air supply, or brief interruptions in the air supply, the pneumatic ball valve cannot open or close properly. Providing an additional air supply for the pneumatic ball valve not only increases equipment costs but also makes the entire system structure more complex, reducing the equipment's economy and practicality. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a pneumatic ball valve assembly that, by setting up an air storage tank, diverts and stores compressed air from the air source to supply air to the pneumatic ball valve, thereby ensuring the normal operation of the pneumatic ball valve.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a pneumatic ball valve assembly, comprising:

[0005] The main air pipe has one end connected to the air source and the other end connected to the working equipment.

[0006] A pneumatic ball valve, installed on the main air pipe, is used to control the opening and closing of the air passage between the air source and the working equipment;

[0007] The gas storage tank has an inlet end connected to a pressure reducing valve via a pipe, and the pressure reducing valve is connected to the main gas pipe between the gas source and the pneumatic ball valve via a pipe.

[0008] The solenoid valve has its inlet end connected to the outlet end of the air storage tank via pipe three, and its outlet end connected to the inlet of the pneumatic actuator of the pneumatic ball valve via pipe four.

[0009] Preferably, the pressure reducing valve is connected to the pipeline via a one-way valve, which controls the airflow to be delivered unidirectionally from the pipeline to the pressure reducing valve.

[0010] Preferably, the second pipe is an oil pipe, and the first, third and fourth pipes are all gas pipes.

[0011] Preferably, the pneumatic ball valve is a pneumatic threaded ball valve, and the pneumatic actuator of the pneumatic threaded ball valve is a double-acting pneumatic actuator.

[0012] Preferably, a drain valve is provided at the bottom of the gas storage tank.

[0013] Preferably, the exhaust port of the pressure reducing valve is equipped with a silencer.

[0014] Preferably, the main air pipe is fixed to the frame by multiple U-bolts.

[0015] Preferably, the gas storage tank is equipped with an exhaust valve for maintaining gas pressure.

[0016] Preferably, the gas storage tank is fixed to the frame by a gas tank clamp.

[0017] Preferably, an oil mist lubricator is installed on the main air pipe between the working device and the pneumatic ball valve.

[0018] The beneficial effects of this utility model are as follows:

[0019] The gas storage tank designed in this utility model is connected to the main gas pipe through pipe one, pressure reducing valve, and pipe two. The gas source can provide power to the working equipment through the main gas pipe, and can also store gas at a certain pressure in the gas storage tank. The gas in the gas storage tank can be used to control the opening and closing of the pneumatic ball valve. The start and stop of the working equipment can be controlled without an additional gas source, which improves the overall practicality and economy of the equipment.

[0020] The one-way valve between the pressure reducing valve and the pipeline ensures that the airflow is delivered to the pressure reducing valve only from the pipeline, preventing the gas in the gas storage tank from flowing back into the gas source and preventing the pressure reducing valve from failing due to reverse pressure, thus further ensuring the stability of air pressure control; the oil mist lubricator between the working equipment and the pneumatic ball valve can atomize the lubricating oil and mix it into the airflow to lubricate the inside of the working equipment, reduce friction and wear, and extend the service life of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 2 As shown, Embodiment 1 of this utility model provides a pneumatic ball valve 9 assembly, including a main air pipe, a pneumatic ball valve 9, an air tank 24, a solenoid valve 4, and other components. The main air pipe is a galvanized pipe 8, with one end connected to the pneumatic ball valve 9 and the other end connected to an oil mist lubricator 7. The end of the pneumatic ball valve 9 furthest from the galvanized pipe 8 is connected to a straight connector 10. The end of the oil mist lubricator 7 furthest from the galvanized pipe 8 is connected to a straight connector 20. Straight connector 10 is connected to an air source, which can be an air compressor. Straight connector 20 is connected to a working device, which can be an impactor.

[0029] The pneumatic ball valve 9 of this utility model can be a pneumatic threaded ball valve or other types of pneumatic ball valve 9. In this embodiment, a pneumatic threaded ball valve is used. The pneumatic actuator of this pneumatic threaded ball valve is a double-acting pneumatic actuator with two air inlets. By alternately supplying air to the two air inlets, the pneumatic actuator can drive the valve core to rotate forward and backward, thereby adjusting the opening and closing state of the pneumatic ball valve 9. The two ends of the pneumatic ball valve 9 are securely connected to the galvanized pipe 8 and the straight connector 10 through threaded connections, which are responsible for controlling the air passage between the air source and the working equipment. The straight connector 10, the galvanized pipe 8, and the straight connector 2 5 are respectively fixed to the frame with three U-bolts 6.

[0030] The gas storage tank 24 is a cylindrical metal tank, which is fixed to an empty position on the frame by two gas tank clamps 25. The air inlet of the gas storage tank 24 is connected to the pressure reducing valve 23 through an air pipe (i.e., pipe 15). The pressure reducing valve 23 is fixed to the frame by hexagonal head bolts 18. The pressure reducing valve 23 is connected to the straight connector 10 between the air source and the pneumatic ball valve 9 through an oil pipe (i.e., pipe 21), so that while the air source supplies air to the impactor, it can reduce the pressure of some air through the pressure reducing valve 23 and store it in the gas storage tank 24.

[0031] Solenoid valve 4 is fixedly installed on the frame by round-headed cross bolts 19. The air inlet of solenoid valve 4 is connected to the pneumatic bend external thread plug on the top of air tank 24 through an air pipe (i.e., pipe three 22). The two air outlets of solenoid valve 4 are respectively connected to the two air inlets of the pneumatic actuator of pneumatic ball valve 9 through two air pipes (i.e., pipe four 12).

[0032] When the impactor needs to be started, the gas in the air tank 24 enters the pneumatic actuator of the pneumatic ball valve 9 through the solenoid valve 4, pushing the pneumatic ball valve 9 to open, allowing the air from the air compressor to smoothly enter the impactor and drive it to work. When it needs to be stopped, the solenoid valve 4 controls the pneumatic ball valve 9 to close, cutting off the air supply. The oil mist lubricator 7 atomizes lubricating oil and mixes it into the airflow to lubricate the inside of the impactor, reduce friction and wear, and extend the service life of the equipment.

[0033] Example 2:

[0034] Based on Embodiment 1, in Embodiment 2, an exhaust valve 21 for maintaining stable air pressure is also installed on the top of the tank. When the air pressure inside the tank exceeds a set value, it automatically releases air. A one-way valve 14 and a pipe connector 13 are installed at the inlet end of the pressure reducing valve 23. The pipe connector 13 is connected to pipe 15. Airflow can only be delivered from pipe 15 through the one-way valve 14 to the pressure reducing valve 23, ensuring that gas in the gas storage tank 24 does not flow back into the gas source, thus ensuring the normal operation of the pressure reducing valve 23. A pneumatic bend external threaded plug 20 is fixed to the top of the gas storage tank 24. A pneumatic bend external threaded plug 22 is fixed to the inlet end of the solenoid valve 4. Both ends of pipe 3 22 are fixed to the pneumatic bend external threaded plug 20 and pneumatic bend external threaded plug 22 respectively using locking nuts. Two pneumatic straight external threaded plugs 3 are fixed to the outlet end of the solenoid valve 4. Two pipes 4 12 are fixedly connected to the two pneumatic straight external threaded plugs 3 respectively.

[0035] Example 3:

[0036] Based on Embodiments 1 and 2, two straight-through connectors at the bottom of the gas storage tank 24 are respectively equipped with a drain valve 26 and a flange plug 27. The drain valve 26 is used to periodically drain the condensate in the gas storage tank 24 to ensure the gas is dry. A flat-headed silencer 1 is installed at the exhaust port of the pressure reducing valve 23, which can effectively reduce exhaust noise. A pneumatic bend external thread plug three 16 is fixed to the side of the gas storage tank 24, and a pneumatic straight-through external thread plug two 17 is fixed to the outlet end of the pressure reducing valve 23. The two ends of the pipe one 15 are respectively fixed to the pneumatic bend external thread plug three 16 and the pneumatic straight-through external thread plug two 17.

[0037] In use, a portion of the gas source is directly supplied to the working equipment via the main gas pipe, while the other portion is stored in the gas storage tank 24 through pipe 21, pressure reducing valve 23, and pipe 15. A one-way valve 14 prevents backflow of gas from the gas storage tank 24. When it is necessary to control the start and stop of the equipment, the gas in the gas storage tank 24 enters the double-acting pneumatic actuator of the pneumatic ball valve 9 through pipe 32, solenoid valve 4, and pipe 412, driving the valve core to rotate and controlling the opening and closing of the gas path.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
