Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of valve testing equipment, and more specifically, it relates to safety valve life testing equipment. Background Technology
[0002] As a component that ensures the safe operation of various industrial equipment, safety valves automatically open to release pressure when the system pressure exceeds the set safety threshold during industrial production, preventing safety accidents caused by excessive pressure. To ensure that safety valves can function stably in actual use, they need to undergo life testing before being put into use.
[0003] Currently, the industry's commonly used method for testing the lifespan of safety valves is to simulate actual working conditions and perform multiple venting operations on the safety valve to test its performance during frequent opening and closing. Typically, safety valves undergo 100,000 venting tests to verify their durability and stability. However, after completing the specified number of venting tests, existing testing equipment requires personnel to disassemble the safety valve from the lifespan testing equipment and transfer it to a safety valve performance tester for failure detection. Due to the separation of the testing process, failure information of the safety valve cannot be obtained immediately, resulting in a lack of convenience. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a safety valve life testing device, which solves the technical problem that existing testing devices, due to the separation of the testing process, cannot obtain safety valve failure information in a timely manner, resulting in a lack of convenience.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] This utility model provides a safety valve life testing device, comprising a base 11 and a housing 12 on top of it. A pressure reducing valve 13 is installed on one side of the housing 12, which is connected to an external gas source through a sealed joint. The pressure reducing valve 13 can adjust the gas pressure input from the external gas source to the range that meets the testing requirements, providing a stable gas source for the testing process. A through groove is opened on one side of the housing 12, and a button base plate 14 is installed in the through groove. A button plate 15 is installed on one side of the button base plate 14, and multiple flow meters 16 are set on the button plate 15 to display the gas flow in real time. During the safety valve life testing process, when a valve 18 under test fails, the gas flow will change abnormally. The operator can read the flow data through the corresponding flow meter 16 to detect the failure, making the testing process more intuitive and visible. On the other side of the button base plate 14, multiple pressure sensors 17 are installed corresponding to the multiple flow meters 16. When the safety valve is tested for ventilation, the gas pressure can be monitored in real time. A clamp assembly for placing the valve 18 under test is installed on the top of the base 11.
[0026] Please see as follows Figure 3 and Figure 4As shown, the fixture assembly includes a detection base plate 31. The top of the base 11 is connected to the detection base plate 31 by multiple sets of columns to ensure a firm connection. Multiple sets of first mounting holes 32 are opened on the detection base plate 31. Fixture bases 33 are installed in each of the multiple sets of first mounting holes 32. Detection fixtures 34 are provided on the top of each of the multiple sets of fixture bases 33. Fixing holes 35 are opened at the top of each detection fixture 34. Internal threads are provided on the inner wall of the fixing holes 35 corresponding to the pressure reducing valve 13. When installing the valve to be tested 18, the operator tightens the threaded section at the bottom of the pressure reducing valve 13 into the fixing hole 35. Taking advantage of the convenience of the threaded connection, the valve to be tested 18 can be quickly installed and removed. The outlet ends of multiple sets of flow meters 16 are connected to the multiple sets of fixture bases 33 through separate pipes to ensure that the gas is smoothly delivered to the valve to be tested 18.
[0027] Please see as follows Figure 2 As shown, a solenoid valve 19 is installed on the top of the base 11. The outlet of the pressure reducing valve 13 is connected to the solenoid valve 19 through a pipe. The solenoid valve 19 is a combined solenoid valve, with multiple sets of connecting pipes corresponding to multiple sets of pressure sensors 17. During the detection process, the solenoid valve 19 can independently control the flow of gas to multiple valves 18 to be tested. When a valve 18 to be tested is being tested, the connecting pipe corresponding to the solenoid valve 19 can be opened to allow gas to flow into the corresponding detection circuit, thereby realizing the independent detection of multiple sets of valves 18 to be tested. The multiple sets of pressure sensors 17 are connected to the inlet of multiple sets of flow meters 16.
[0028] Please see as follows Figure 2 and Figure 4 As shown, each of the multiple flowmeters 16 has a vent switch 20 installed at its bottom. Each vent switch 20 is electrically connected to a solenoid valve 19, allowing independent control of the venting status of each flowmeter 16. When a particular valve 18 fails, the operator can operate the vent switch 20 to shut off the corresponding circuit without affecting the testing process of other valves 18. A controller 21 is installed on the inner wall of the housing 12, and status indicator lights 22 are installed on the top of the multiple flowmeters 16. The solenoid valve 19 and the status indicator lights 22 are electrically connected to the controller 21. When testing a particular valve 18, the operator opens the corresponding vent switch 20 to start the test. Upon receiving the signal, the controller 21 synchronously illuminates the status indicator lights 22. The controller 21 is equipped with a data interface and can be connected to an external terminal via a data cable. The operator can then view the test data on the external terminal, further enhancing the visualization of the testing process.
[0029] A hinged door panel 23 is installed on the back of the housing 12. The door panel 23 is connected to the housing 12 by a hinge, which makes it easy to open the door panel 23 to maintain and repair the internal components. Handles 24 are installed on both sides of the housing 12 for easy gripping by operators, making it convenient to move the equipment and improving the convenience of the testing equipment during use. A plug 25 for connecting to an external power source is installed on one side of the housing 12 to provide a stable power supply for the operation of the equipment.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
