Description

Technical Field

[0001] This utility model relates to the field of pneumatic triplet technology, specifically a pneumatic triplet with an automatic oil replenishment mechanism. Background Technology

[0002] A pneumatic triplet is an integrated auxiliary device in a pneumatic system, consisting of three core functional components connected in series and mounted on the same mounting plate or bracket, typically used as a single module. Its main function is to purify, stabilize, and lubricate the compressed air entering the pneumatic equipment, ensuring the safe, stable, and efficient operation of the pneumatic components.

[0003] Based on the above, the following problems were found: In the current standard pneumatic triplet, the oil mist lubricator requires manual lubrication at regular intervals, which is time-consuming and labor-intensive. If the oil level is too low due to failure to lubricate in time, it will accelerate wear due to insufficient lubrication, shorten the service life of the device, and make it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a pneumatic triplet with an automatic oil replenishment mechanism in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic triplet with an automatic oil replenishment mechanism to solve the problems mentioned in the background art.

[0006] A pneumatic triplet with an automatic oil replenishment mechanism includes a pneumatic triplet body. The pneumatic triplet body includes an oil mist lubricator. A fixing ring is fixedly installed on one side of the oil mist lubricator. An oil replenishment component is fixedly installed inside the fixing ring. A fixing base is fixedly installed at the lower end of the oil mist lubricator. An oil cup is fixedly installed inside the fixing base. An oil replenishment interface is opened on one side of the oil cup. An air hole is opened in the middle of the bottom end of the oil mist lubricator. An oil delivery pipe is fixedly installed on one side of the air hole, and a liquid level sensor is fixedly installed on the other side of the air hole. The oil replenishment component includes an oil replenishment bottle. The oil replenishment bottle is disposed in the fixing ring. A first solenoid valve is fixedly installed on the top of the oil replenishment bottle. The top of the first solenoid valve is connected to an oil filling interface. A second solenoid valve is fixedly installed on the bottom of the oil replenishment bottle. A connecting interface is connected on one side of the second solenoid valve. The connecting interface is connected to the oil replenishment interface.

[0007] By adopting the above technical solution, the oil mist lubricator facilitates the injection of a small amount of lubricating oil mist into clean, stabilized compressed air to lubricate actuators such as cylinders and solenoid valves. The fixing ring facilitates the fixed installation of the oil replenishment component on one side of the oil mist lubricator. The oil cup facilitates the storage of lubricating oil, allowing the oil mist lubricator to spray oil mist. The oil replenishment interface facilitates the connection between the oil cup and the oil replenishment component, enabling the component to replenish oil to the inside of the oil cup. The air vent facilitates the injection of compressed air into the oil cup, forcing the lubricating oil into the oil mist lubricator for atomization. The oil delivery pipe facilitates the transport of lubricating oil from the oil cup to the oil mist lubricator for atomization. The liquid level sensor facilitates monitoring... The system measures the remaining lubricating oil level in the oil cup to trigger a refill signal. The refill port facilitates connection to an external oil supply line, allowing lubricating oil to be injected into the refill bottle. A first solenoid valve controls the opening and closing of the refill port. The connection between the refill bottle and the oil cup allows for easy connection between them. When the level sensor detects insufficient lubricating oil in the oil cup, it controls the first solenoid valve to close the refill port and opens the second solenoid valve, allowing air from inside the oil cup to enter the refill bottle. This allows lubricating oil from the refill bottle to flow into the oil cup for replenishment. After refilling, the second solenoid valve closes and the first solenoid valve opens, allowing the external oil supply line to fill the refill bottle with lubricating oil, facilitating the next round of refilling.

[0008] Furthermore, the top of the oil mist lubricator is provided with an observation cover, and the top of the observation cover is provided with an oil mist adjustment knob.

[0009] By adopting the above technical solution, and with the setting of the observation cover and oil mist adjustment knob, the operator can directly observe the oil mist generation status through the observation cover, and adjust the oil mist adjustment knob to adjust the oil dripping amount or atomization intensity of the oil mist generator to control the degree of lubrication.

[0010] Furthermore, one end of the oil mist lubricator is provided with an air outlet, and the other end of the oil mist lubricator is connected to a pressure reducing valve.

[0011] By adopting the above technical solution and setting the air outlet, it is easy to connect to external pneumatic equipment and convenient to output purified, pressure-stabilized and lubricated air to the pneumatic equipment.

[0012] Furthermore, one end of the pressure reducing valve is connected to an air filter, and one end of the air filter has an air inlet.

[0013] By adopting the above technical solution and setting the air inlet, it is easy to connect to a compressed air source, and convenient for compressed air to enter the device for purification, pressure stabilization and lubrication.

[0014] Furthermore, a connecting seat is fixedly installed between the pressure reducing valve, the air filter, and the oil mist lubricator. The connecting seat has a mounting hole in the middle. The pressure reducing valve is installed between the two connecting seats, and the air filter is provided on the side of one of the connecting seats away from the pressure reducing valve.

[0015] By adopting the above technical solution and setting the connecting seat, it is easy to fix and seal the pressure reducing valve to the air filter and oil mist lubricator at both ends.

[0016] Furthermore, a mounting ear is fixedly installed at one end of the connector, and screw holes are provided at both ends of the mounting ear.

[0017] By adopting the above technical solution, the installation ears and screw holes facilitate the use of fixing screws to fix the device in a designated position.

[0018] Furthermore, a water collection cup is fixedly installed at the bottom of the air filter, and a drain valve is fixedly installed at the bottom of the water collection cup.

[0019] By adopting the above technical solution and setting up a water collection cup, it is easy to collect the moisture and impurities separated by the air filter and prevent them from entering the subsequent system.

[0020] Furthermore, a pressure gauge is fixedly installed on one side of the pressure reducing valve, and a pressure adjusting handle is provided at the bottom of the pressure reducing valve.

[0021] By adopting the above technical solution, the pressure gauge and pressure regulating handle are set to facilitate the real-time display of the current output pressure value by the pressure gauge, and the pressure regulating handle is manually rotated to set the output pressure. This allows the pressure reducing valve to adjust the high-pressure intake to a stable low-pressure output, thus meeting the working pressure requirements of downstream equipment.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The oil mist lubricator facilitates the injection of a small amount of lubricating oil mist into clean, stabilized compressed air to lubricate actuators such as cylinders and solenoid valves. The fixing ring facilitates the fixed installation of the oil replenishment component on one side of the oil mist lubricator. The oil cup facilitates the storage of lubricating oil and allows the oil mist lubricator to spray oil mist. The oil replenishment interface facilitates the connection between the oil cup and the oil replenishment component, allowing the component to replenish oil to the inside of the oil cup. The air vent facilitates the injection of compressed air into the oil cup, forcing the lubricating oil into the oil mist lubricator for atomization. The oil delivery pipe facilitates the delivery of lubricating oil from the oil cup to the oil mist lubricator for atomization. The liquid level sensor facilitates the monitoring of the remaining lubricating oil in the oil cup, allowing for the triggering of an oil replenishment signal. The refueling interface facilitates connection to external oil pipelines, allowing lubricating oil to be injected into the replenishment bottle. A first solenoid valve controls the opening and closing of the refueling interface. This interface connects the replenishment bottle to the oil cup. When the level sensor detects insufficient lubricating oil in the oil cup, it controls the first solenoid valve to close the refueling interface and opens the second solenoid valve, allowing air from inside the oil cup to enter the replenishment bottle. This allows lubricating oil from the replenishment bottle to flow into the oil cup for replenishment. After replenishment, the second solenoid valve closes and the first solenoid valve opens, allowing external oil pipelines to fill the replenishment bottle with lubricating oil, facilitating the next round of replenishment. This invention automatically replenishes lubricating oil into the oil cup without requiring manual shutdown for refueling, improving the continuity and reliability of equipment operation and possessing high practical value.

[0029] 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.

[0030] Please see Figures 1-5This utility model provides a technical solution: a pneumatic triplet with an automatic oil replenishment mechanism, comprising a pneumatic triplet body 1, which includes an oil mist lubricator 18. The oil mist lubricator 18 facilitates the injection of a small amount of lubricating oil mist into clean, stabilized compressed air to lubricate actuators such as cylinders and solenoid valves. A fixing ring 19 is fixedly installed on one side of the oil mist lubricator 18, allowing the oil replenishment component 2 to be fixedly installed on that side. The oil replenishment component 2 is fixedly installed inside the fixing ring 19. A fixing seat 116 is fixedly installed at the lower end of the oil mist lubricator 18, and an oil cup 110 is fixedly installed inside the fixing seat 116. The design of the cup 110 facilitates the storage of lubricating oil and allows the oil mist atomizer 18 to spray oil mist. An oil replenishment port 111 is provided on one side of the cup 110, allowing for easy connection between the cup 110 and the oil replenishment assembly 2, enabling the assembly 2 to replenish oil to the inside of the cup 110. An air hole 119 is located at the center of the bottom of the oil mist atomizer 18, allowing compressed air to be forced into the cup 110, thus atomizing the lubricating oil. An oil delivery pipe 117 is fixedly installed on one side of the air hole 119, facilitating the delivery of lubricating oil from the cup 110 to the oil mist atomizer 18. The system atomizes the lubricating oil, and a liquid level sensor 118 is fixedly installed on the other side of the vent 119. The liquid level sensor 118 facilitates monitoring the remaining lubricating oil level inside the oil cup 110, allowing for easy triggering of a replenishment signal. The replenishment assembly 2 includes a replenishment bottle 21. A first solenoid valve 22 is fixedly installed on the top of the replenishment bottle 21, and a filling port 23 is connected to the top of the first solenoid valve 22. The filling port 23 facilitates connection to an external oil supply line, allowing lubricating oil to be injected into the replenishment bottle 21. The first solenoid valve 22 controls the opening and closing of the filling port 23. A second solenoid valve 24 is fixedly installed on the bottom of the replenishment bottle 21, and a connection port is connected to one side of the second solenoid valve 24. 25. The connecting interface 25 is connected to the oil replenishment interface 111. The connecting interface 25 facilitates the connection between the oil replenishment bottle 21 and the oil cup 110. When the liquid level sensor 118 detects that the lubricating oil level in the oil cup 110 is insufficient, it controls the first solenoid valve 22 to close the oil filling interface 23 and open the second solenoid valve 24, allowing the air inside the oil cup 110 to enter the oil replenishment bottle 21, so that the lubricating oil inside the oil replenishment bottle 21 can flow into the oil cup 110 for replenishment. After the oil replenishment is completed, the second solenoid valve 24 is closed and the first solenoid valve 22 is opened, so that the external oil supply line can fill the oil replenishment bottle 21 with lubricating oil, which is convenient for the next round of oil replenishment in the oil cup 110.

[0031] The oil mist lubricator 18 has an observation cover 112 at its top, and an oil mist adjustment knob 113 at the top of the observation cover 112. The observation cover 112 and the oil mist adjustment knob 113 allow operators to directly observe the oil mist generation status through the observation cover 112. The oil mist adjustment knob 113 adjusts the oil delivery speed of the oil mist lubricator 18, controlling the degree of lubrication. In this embodiment, the observation cover 112 is made of transparent material. The connection between the oil mist adjustment knob 113 and the oil mist lubricator 18 is existing technology and will not be described further here. For example, the lower end of the oil mist adjustment knob 113 may have a threaded rod, and the end of the threaded rod may have a stop. The threaded rod and the observation cover 112 are threaded together. Rotating the adjustment knob 113 rotates the threaded rod, which in turn moves the stop to block the oil delivery groove inside the oil mist lubricator 18, thus adjusting the oil delivery speed.

[0032] The oil mist lubricator 18 has an air outlet 115 at one end and a pressure reducing valve 15 at the other end. The air outlet 115 facilitates connection to external pneumatic equipment and allows for the output of purified, pressure-stabilized, and lubricated air to the pneumatic equipment.

[0033] The pressure reducing valve 15 is connected to an air filter 11 at one end, and an air inlet 13 is provided at one end of the air filter 11. The air inlet 13 facilitates the connection to a compressed air source, allowing compressed air to enter the device for purification, pressure stabilization, and lubrication.

[0034] The pressure reducing valve 15 is fixedly mounted with a connecting seat 114 between it and the air filter 11 and the lubricator 18. The connecting seat 114 has a mounting hole 120 in its center. The pressure reducing valve 15 is installed between the two connecting seats 114, with the air filter 11 located on the side of one connecting seat 114 furthest from the pressure reducing valve 15. The connecting seats 114 facilitate the connection and sealing of the pressure reducing valve 15 with the air filters 11 and lubricators 18 at both ends. The mounting hole 120 facilitates the installation of piping, allowing the pressure reducing valve 15 to be connected to the air filters 11 and lubricators 18 at both ends. The pressure reducing valve 15 is clamped between the two connecting seats 114.

[0035] The connector 114 has a mounting ear 121 fixedly installed at one end. The mounting ear 121 has screw holes 122 at both ends. The mounting ear 121 and screw holes 122 make it easy to use screws to fix the device in a designated position.

[0036] The air filter 11 has a water collection cup 12 fixedly installed at the bottom, and a drain valve 14 fixedly installed at the bottom of the water collection cup 12. The water collection cup 12 is designed to facilitate the collection of water and impurities separated by the air filter 11, preventing them from entering the subsequent system.

[0037] The pressure reducing valve 15 is fixedly equipped with a pressure gauge 16 on one side and a pressure regulating handle 17 at the bottom. The pressure gauge 16 and the pressure regulating handle 17 allow the pressure gauge 16 to display the current output pressure value in real time. The pressure regulating handle 17 can be manually rotated to set the output pressure, so that the pressure reducing valve 15 can adjust the high-pressure intake to a stable low-pressure output to meet the working pressure requirements of downstream equipment.

[0038] Specifically, the working principle of this pneumatic triplet with an automatic oil replenishment mechanism is as follows: During use, the mounting ears 121 and screw holes 122 facilitate the use of fixing screws to secure the device to a designated position. The connecting seat 114 facilitates the fixed connection and sealing of the pressure reducing valve 15 with the air filters 11 and oil mist lubricator 18 at both ends. The air inlet 13 facilitates connection to a compressed air source, allowing compressed air to enter the device for purification, pressure stabilization, and lubrication. The water collection cup 12 facilitates the collection of moisture and impurities separated by the air filter 11, preventing them from entering subsequent systems. The pressure gauge 16 and pressure regulating handle 17 facilitate real-time pressure adjustment. The current output pressure value is displayed. The pressure regulating handle 17 is manually rotated to set the output pressure, allowing the pressure reducing valve 15 to adjust the high-pressure intake air to a stable low-pressure output, meeting the working pressure requirements of downstream equipment. The observation cover 112 and oil mist regulating knob 113 allow operators to directly observe the oil mist generation status through the observation cover 112. The oil mist regulating knob 113 adjusts the delivery speed of the lubricating oil in the oil mist lubricator 18, controlling the degree of lubrication. The air outlet 115 facilitates connection to external pneumatic equipment, allowing purified, stabilized, and lubricated air to be output to the pneumatic equipment. The fixing ring 19 facilitates the fixed installation of the oil replenishment component 2 on one side of the oil mist lubricator 18, and the oil cup 110... The design facilitates the storage of lubricating oil and the spraying of oil mist from the oil mist generator 18. The oil replenishment interface 111 allows for easy connection between the oil cup 110 and the oil replenishment component 2, enabling the component 2 to replenish oil to the inside of the oil cup 110. The air vent 119 allows compressed air to be forced into the oil cup 110, atomizing the lubricating oil into the oil mist generator 18. The oil delivery pipe 117 facilitates the delivery of lubricating oil from the oil cup 110 to the oil mist generator 18 for atomization. The level sensor 118 monitors the remaining lubricating oil level in the oil cup 110, triggering a replenishment signal. The oil filling interface 23 allows for connection to an external oil supply line, facilitating the delivery of lubricating oil. The lubricating oil is injected into the replenishment bottle 21. The first solenoid valve 22 controls the opening and closing of the refueling port 23. The connection port 25 facilitates the connection between the replenishment bottle 21 and the oil cup 110. When the level sensor 118 detects that the lubricating oil level in the oil cup 110 is insufficient, it controls the first solenoid valve 22 to close the refueling port 23 and opens the second solenoid valve 24, allowing air inside the oil cup 110 to enter the replenishment bottle 21. This allows the lubricating oil inside the replenishment bottle 21 to flow into the oil cup 110 for replenishment. After replenishment is completed, the second solenoid valve 24 is closed and the first solenoid valve 22 is opened, allowing the external oil supply line to fill the replenishment bottle 21 with lubricating oil, facilitating the next round of replenishment of the oil cup 110.
