[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] This utility model discloses a compressor valve 400 sensitivity detection device, which can solve the technical problem of long maintenance time caused by repeated disassembly in the prior art.

[0031] The technical solution of this application will be described in detail below through specific embodiments:

[0032] See Figure 1 , Figure 2 and Figure 3 This application discloses a sensitivity detection device for a compressor valve 400, comprising a base 100, a fastening structure 200, and a gas delivery structure 300. The base 100 includes a mounting cavity 102 and a through hole 106. One sidewall of the mounting cavity 102 is a limiting wall 103, and the through hole 106 is located in the limiting wall 103, penetrating the limiting wall 103 and communicating with the mounting cavity 102. The fastening structure 200 is mounted on a fastening wall 104 opposite to the limiting wall 103, and the fastening structure 200 is used to fix the valve 400 to the limiting wall 103. The gas delivery structure 300 communicates with the valve 400 through the through hole 106.

[0033] The compressor valve 400 sensitivity testing device disclosed in this embodiment implements a maintenance mode where the valve 400 is repaired first, then its sensitivity is tested on a specialized testing device, and finally a decision is made on whether to put it into use. This process avoids the cumbersome process of repeatedly testing the valve 400 in traditional methods, optimizes the maintenance process, and improves work efficiency.

[0034] The detection device supplies gas to the valve 400 through the gas supply structure 300, simulating the gas pressure and flow conditions of the valve 400 in actual operation. By controlling the air intake and unloading, the device can more accurately determine the opening and closing sensitivity and usability of the valve 400. Because the detection conditions are closer to actual working conditions, it reduces misjudgments caused by discrepancies between the test conditions and actual working conditions, thus improving the accuracy of the detection.

[0035] In one embodiment, the gas transmission structure 300 includes an external gas source 301 and a connecting pipe 302, with both ends of the connecting pipe 302 connected to the external gas source 301 and the through hole 106, respectively.

[0036] An external gas source 301 ensures a stable gas supply during the testing process. The external gas source 301 typically has a large gas storage capacity and stable output pressure, meeting the gas flow and pressure requirements of the testing device, thereby guaranteeing the accuracy and reliability of the test results.

[0037] The connecting pipe 302 serves as a bridge between the external gas source 301 and the detection device, offering a flexible connection method. Its length and angle can be adjusted according to actual needs to adapt to detection devices in different positions and layouts. Furthermore, the connecting pipe 302 is typically made of pressure-resistant and corrosion-resistant materials, ensuring the safety and stability of gas transmission.

[0038] In one embodiment, an air intake valve 101 is provided on the base 100, the air intake valve 101 is installed at the through hole 106, and the connecting pipe 302 is connected to the air intake valve 101.

[0039] The inlet valve 101 allows the operator to precisely adjust the gas flow rate entering the detection device as needed. By adjusting the opening of the inlet valve 101, the detection requirements of different types of gas valves 400 and the gas flow rate requirements of different detection stages can be accommodated.

[0040] The inlet valve 101 can serve as part of a safety device to prevent damage to the detection device or valve 400 due to excessive gas pressure. When the gas pressure exceeds a set value, the inlet valve 101 can automatically close or limit the gas flow, thereby protecting the equipment.

[0041] The intake valve 101 typically has an intuitive operating interface (such as a handle, knob, etc.) that allows operators to easily control the gas flow.

[0042] In one embodiment, the two ends of the connecting pipe 302 are respectively provided with a first quick connector and a second quick connector. The first quick connector is connected to the air intake valve 101, and the second quick connector is connected to the external air source 301.

[0043] The quick-connector design makes connecting and disconnecting the connecting pipe 302 to the air inlet valve 101 and the external air source 301 very quick and easy. This greatly reduces the assembly and disassembly time of the detection device and improves work efficiency.

[0044] In one embodiment, the first quick connector is connected to the intake valve 101 via a threaded connection, the second quick connector is connected to the external air source 301 via a threaded connection, and a switch valve is provided between the connecting pipe 302 and the external air source 301.

[0045] Threaded connections are a type of mechanical connection that achieves a tight fit through the interlocking of threads. Their advantages include a stable connection, good sealing, and the ability to withstand certain pressures and vibrations, making them less prone to loosening or leakage. This ensures safe and reliable gas transmission between the connecting pipe 302 and the inlet valve 101, as well as the external gas source 301. In the sensitivity testing of the compressor valve 400, higher gas pressures may be required. Threaded connections can withstand such high-pressure environments, ensuring the stability and accuracy of the testing process.

[0046] While the threaded connection itself requires some rotation, the design of the quick-connect fitting balances stability and convenience to a certain extent.

[0047] In one embodiment, the fastening wall 104 is provided with a threaded hole 107. The fastening structure 200 includes a set screw that is threaded into the threaded hole 107.

[0048] The threaded engagement of the set screw and the threaded hole 107 provides a secure fixation. The threaded connection is self-locking, preventing the air valve 400 from loosening due to vibration or changes in gas pressure during testing.

[0049] In one embodiment, the fastening structure 200 includes one of a cylinder, a hydraulic cylinder, or a push rod.

[0050] The cylinders, hydraulic cylinders, or push rods can all be operated automatically through the control system, eliminating the need for manual tightening and greatly improving the automation level and work efficiency of the testing process. The tightening force of the cylinders, hydraulic cylinders, or push rods can be precisely adjusted through the control system to ensure that the valve 400 receives uniform and appropriate pressure during the testing process, avoiding testing errors or damage to the valve 400 caused by excessive or insufficient tightening force.

[0051] In one embodiment, the compressor valve 400 sensitivity detection device further includes a support block 105. The support block 105 is mounted on the base 100 and is located between the limiting wall 103 and the fastening wall 104.

[0052] The support block 105 is located between the limiting wall 103 and the fastening wall 104, providing an additional support point for the air valve 400 and helping to enhance the structural stability of the entire detection device. This can prevent structural deformation or damage caused by vibration or uneven force on the air valve 400 during the detection process.

[0053] In one embodiment, the support block 105 is slidably connected to the seat 100, and the sliding direction of the support block 105 is perpendicular to the connection line between the limiting wall 103 and the fastening wall 104.

[0054] The support block 105 is slidably connected to the base 100, allowing the position of the support block 105 to be flexibly adjusted according to the actual size of the air valve 400. By sliding the support block 105, it can be ensured that the air valve 400 receives proper support during the testing process, regardless of its size. This design enhances the versatility of the testing device, enabling it to adapt to testing tasks for air valves 400 of various sizes and specifications.

[0055] In one embodiment, the base 100 is provided with a worm gear 108, a turbine gear 109, and a rotating rod 110. The rotating rod 110 is rotatably connected to the support block 105 and slidably connected to the base 100. The turbine gear 109 is keyed to the rotating rod 110 so that the turbine gear 109 and the rotating rod 110 rotate synchronously. The worm gear 108 is rotatably connected to the base 100 and meshes with the turbine gear 109.

[0056] The rotation of the worm gear 108 allows for precise control of the rotation angle of the turbine 109, which in turn drives the rotating rod 110 and the support block 105 to adjust their height. This adjustment method enables operators to easily and accurately adjust the height of the support block 105 according to the specific dimensions of the valve 400 and the testing requirements.

[0057] The turbine 109 and worm gear 108 mechanism has a self-locking characteristic, meaning that when the worm gear 108 stops rotating, the turbine 109, the connected rotating rod 110, and the support block 105 will remain in a fixed position and will not descend due to external forces. This characteristic ensures that the support block 105 can stably support the air valve 400 during the testing process, avoiding testing errors or safety accidents caused by the descent of the support block 105.

[0058] The compressor valve 400 sensitivity detection device disclosed in this application works as follows:

[0059] Ensure that the testing device (including the base 100, limiting wall 103, fastening wall 104, support block 105, turbine 109, worm gear 108 mechanism, etc.) is intact and undamaged, with all components firmly connected and free from looseness or damage. Select an appropriate size and specification of air valve 400 according to the testing requirements, and ensure its surface is clean and free of oil, impurities, etc.

[0060] The air valve 400 is placed on the base 100, with one end in contact with the limiting wall 103 to restrict its movement in a certain direction. By rotating the worm gear 108, the turbine 109 and the rotating rod 110 are driven to rotate, thereby adjusting the height of the support block 105 so that the air inlet of the air valve 400 is aligned with the through hole 106. By rotating the set screw, the set screw is pressed against the side of the air valve 400 away from the limiting wall 103, thus fixing the air valve 400.

[0061] Connect the second quick connector to the external gas source 301 via a threaded connection, ensuring a secure and well-sealed connection. The switch valve between the connecting pipe 302 and the external gas source 301 should be in the closed position. After preparation, slowly open the switch valve to allow gas to enter the detection device.

[0062] Depending on the specific design of the testing device, initiate the corresponding testing procedure or perform manual operation to test the sensitivity of the gas valve 400. This may include observing the opening and closing actions of the gas valve 400, measuring changes in gas flow rate or pressure, etc. During the testing process, record relevant data in a timely manner, such as the opening time and closing time of the gas valve 400, gas flow rate or pressure, etc., for subsequent analysis and evaluation.

[0063] Based on the recorded data, assess whether the sensitivity of valve 400 meets the requirements. If the sensitivity of valve 400 is not up to standard, further inspection or replacement of valve 400 may be necessary.

[0064] Through the above embodiments, this application has the following beneficial effects or advantages: The compressor valve 400 sensitivity testing device disclosed in this application eliminates the need for maintenance workers to repeatedly disassemble the valve 400 for testing; they only need to install the valve 400 on the device to perform sensitivity testing, greatly shortening maintenance time. Since the testing process does not require repeated disassembly of the valve 400, manual operation is reduced, lowering labor costs. This device, by simulating the gas pressure and flow conditions of the valve 400 in actual operation, can more accurately determine the opening and closing sensitivity and availability of the valve 400. The fastening structure 200 and support block 105 of this device can be adjusted according to valves 400 of different sizes, exhibiting strong adaptability.
