Description

Technical Field

[0001] The utility model relates to the technical field of lubrication control, in particular to a novel volume detection valve. Background Art

[0002] In the field of lubrication control technology, volumetric flow control valves are key components in ensuring the proper functioning of lubrication systems. Their primary function is to monitor and control the oil volume within the lubrication system to maintain proper oil pressure and quantity, thereby ensuring smooth equipment operation and extending its service life. However, traditional volumetric flow control valves have inherent design limitations that restrict their performance and reliability.

[0003] Traditional volumetric sensing valves typically utilize a relatively simple piston structure, where changes in oil pressure drive the piston, thereby changing the valve's state. However, this design often results in significant friction and hysteresis during piston movement, affecting the valve's response speed and accuracy. Furthermore, traditional sealing mechanisms are prone to wear and leakage, further reducing valve performance and reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a novel volume detection valve that addresses the problems identified in the aforementioned background art. By properly configuring a return spring, the piston can be quickly reset to its intermediate position after movement, thereby reducing friction and hysteresis, and improving the valve's response speed and accuracy. Furthermore, the return spring can also compensate for wear and leakage of the sealing mechanism to a certain extent, thereby extending the valve's service life.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new volume detection valve, comprising a valve body, a reversing cavity penetrating the valve body along the length direction of the valve body, a piston assembly movably arranged in the reversing cavity and moving left and right along the reversing cavity as the oil pressure changes, the piston assembly divides the reversing cavity into two left and right chambers, sealing mechanisms are provided at both ends of the reversing cavity, an oil guide channel respectively connecting the two chambers is provided on the valve body, and a reset spring is provided in the reversing cavity at a position corresponding to the two ends of the piston assembly and the sealing mechanism.

[0006] In order to further optimize the present invention, the following technical solutions may be preferably used:

[0007] Preferably, the sealing mechanism comprises a first sealing plug and a second sealing plug which are respectively threadedly rotated on the two ends of the reversing cavity. A receiving groove is provided in the second sealing plug, and a Hall sensor is provided in the receiving groove.

[0008] Preferably, the piston assembly includes a piston column, a piston coaxially arranged in the middle of the piston column and cooperating with the inner wall of the reversing chamber, and limit rods extending from the pistons at both ends of the piston column are provided, and the limit rods are used to prevent the piston from blocking the oil guide channel.

[0009] Preferably, a magnet cooperating with the Hall sensor is provided at the end of the limiting rod corresponding to one side of the second sealing plug.

[0010] Preferably, a sensor connector for installing a Hall sensor is provided in the accommodating groove, and the sensor connector includes a fixed sleeve and a rotating sleeve. The rotating sleeve can be rotatably set on the fixed sleeve, and the fixed sleeve is provided with an internal thread that cooperates with the end of the second sealing plug, and the second sealing plug is provided with an external thread that cooperates with the internal thread.

[0011] Preferably, the rotating sleeve includes a first joint and a second joint that are threadedly connected. The first joint and the second joint are respectively arranged on both sides of the fixed pipe, and the second joint is provided with a threaded interface for installing a Hall sensor.

[0012] Preferably, a plurality of mounting holes are evenly distributed on the valve body.

[0013] Beneficial effects:

[0014] (1) Improved response speed and accuracy: By introducing a return spring mechanism, this volume detection valve can quickly reset the piston assembly to the middle position after the oil pressure changes, significantly reducing the lag time of the piston movement, thereby improving the response speed and accuracy of the valve body. This enables the lubrication system to adjust the oil pressure and oil volume more promptly, ensuring stable operation of the equipment.

[0015] (2) Enhanced sealing performance and durability: The introduction of a return spring not only facilitates the rapid reset of the piston assembly, but also compensates for the wear of the sealing mechanism to a certain extent, reducing the risk of leakage. At the same time, the elastic effect of the return spring can alleviate the direct impact between the piston and the sealing mechanism, extending the service life of the sealing mechanism and improving the durability of the entire valve body.

[0016] (3) Optimize lubrication control: Because the volume detection valve can quickly and accurately respond to oil pressure changes and precisely control the volume and flow direction of the oil, it can more effectively maintain the oil pressure stability of the lubrication system and reduce equipment wear and failure caused by oil pressure fluctuations. This helps improve the overall performance and operating efficiency of the equipment.

[0017] (4) Simplified maintenance and operation: The automatic reset function of the reset spring reduces the need for manual intervention, reducing maintenance costs and workload. At the same time, the structural design of this volume detection valve is relatively simple, easy to install and debug, and improves operational convenience.

[0018] In summary, the novel volume detection valve of this utility model has significant benefits in the field of lubrication control technology. It not only improves the valve's response speed and accuracy, but also enhances sealing performance and durability, optimizes lubrication control, and simplifies maintenance and operation. These advantages make this volume detection valve widely applicable in various lubrication systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] See also Figure 1-4 A new type of volume detection valve includes a valve body 1, a reversing cavity 7 that runs through the valve body along the length direction of the valve body, a piston assembly that moves left and right along the reversing cavity as the oil pressure changes is movably installed in the reversing cavity, and the piston assembly divides the reversing cavity into two left and right chambers. Sealing mechanisms are installed at both ends of the reversing cavity, and an oil guide channel 6 that connects the two chambers respectively is opened on the valve body. A return spring 11 is installed in the reversing cavity at a position corresponding to the two ends of the piston assembly and the sealing mechanism.

[0026] The sealing mechanism includes a first sealing plug 3 and a second sealing plug 4, which are respectively threaded and rotated at the two ends of the reversing chamber. The second sealing plug 4 has a receiving groove formed therein, and a Hall sensor 17 is installed in the receiving groove. The Hall sensor 17 installed in the second sealing plug can monitor the position and movement status of the piston assembly in real time, providing reliable data support for the precise control of the lubrication system. Through the feedback of the Hall sensor, the system can more accurately adjust the oil pressure and oil volume, realize intelligent control of the lubrication system, and improve the operating efficiency and stability of the equipment. The piston assembly includes a piston rod, and a piston 8 is coaxially mounted in the middle of the piston rod, which cooperates with the inner wall of the reversing chamber. The piston is equipped with a limit rod extending from each end of the piston rod. The limit rod is used to prevent the piston from blocking the oil guide channel. This design cleverly prevents the piston from blocking the oil guide channel during movement, ensuring smooth flow of oil. This optimized piston assembly design not only improves the overall performance of the valve body, but also reduces the risk of failure caused by the piston blocking the oil guide channel.

[0027] The above structural design has the following advantages: (1) By using the first sealing plug and the second sealing plug that are respectively threaded and rotated at the two ends of the reversing chamber as a sealing mechanism, reliable sealing is achieved at both ends of the reversing chamber. This threaded rotation connection method is not only easy to install, but also has excellent sealing effect, which can effectively prevent oil leakage and ensure the stable operation of the lubrication system. At the same time, the receiving groove opened in the second sealing plug and the Hall sensor installed not only do not affect the sealing performance, but also provide convenience for subsequent monitoring and control. (2) Since the sealing mechanism and the piston assembly are designed to be easy to disassemble and install, they can be operated conveniently and quickly when maintenance and replacement are required, reducing maintenance costs and workload. At the same time, this design also facilitates cleaning and inspection of the interior of the valve body, ensuring the long-term stable operation of the valve body.

[0028] As a preferred embodiment, a magnet 10 is mounted on the end of the limiting rod 9, corresponding to the second sealing plug, to mate with a Hall effect sensor. This ensures that the Hall effect sensor can accurately and stably monitor the position and movement of the piston assembly. This design not only improves monitoring accuracy but also enhances system stability, providing a strong guarantee for precise control of the lubrication system.

[0029] As a preferred embodiment, a sensor connector 5 for installing a Hall sensor is installed in the accommodating groove. The sensor connector 5 includes a fixed sleeve 13 and a rotating sleeve. The rotating sleeve can be rotatably installed on the fixed sleeve. The fixed sleeve is provided with an internal thread 15 that cooperates with the end of the second sealing plug, and the second sealing plug is provided with an external thread that cooperates with the internal thread. The rotating sleeve includes a first joint and a second joint that are threadedly connected. The first joint 12 and the second joint 14 are respectively installed on both sides of the fixed pipe. The second joint is provided with a threaded interface 16 for installing the Hall sensor. The design of the above-mentioned sensor connector cleverly solves the difficulties encountered during the installation of the Hall sensor. Through the cooperation of the fixed sleeve and the rotating sleeve, the relative position of the sensor connector can be kept unchanged during the installation process, thereby ensuring that the installation position of the Hall sensor is accurate. At the same time, this design also facilitates subsequent maintenance and replacement work, reducing maintenance costs and workload.

[0030] As a preferred embodiment, multiple mounting holes 2 are evenly distributed on the valve body 1, providing more options for system installation and layout. This design allows for flexible selection of installation locations and methods based on actual needs and space constraints, improving the system's adaptability and flexibility.
