[0002] The diaphragm valve is a stop valve that uses a diaphragm to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body from the inner cavity of the valve cover. The diaphragm is an important component of the diaphragm valve. The service life of the diaphragm plays a vital role in the service life and safe operation of the diaphragm valve.

[0003] The industry standard for diaphragm valves requires that the diaphragm must meet the requirement of 4 million opening and closing times.

At the same time, in the existing durability testing process, the test needs to be stopped after a certain number of tests are completed, and the diaphragm valve must be moved to the testing device for testing by on-site workers. The number of opening and closing times of the diaphragm valve also needs to be calculated manually based on time. In the event of power outages and gas outages, the actual number of tests cannot be accurately known. The combination of the above factors has led to extremely low efficiency in existing diaphragm durability testing.

With such a high opening and closing demand, when testing the durability of the diaphragm valve 100, even if one opening and closing action is performed every 2 seconds, it will take 2 to 3 months; at the same time, in the existing durability performance testing process, after completing a certain number of tests, the test needs to be stopped, and the diaphragm valve 100 must be moved to the testing device by the on-site workers for testing. The number of opening and closing times of the diaphragm valve 100 also needs to be calculated manually based on time. In the event of power outages and gas outages, the actual number of tests cannot be accurately known. The combination of the above factors has led to extremely low efficiency of the existing diaphragm valve durability testing device.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0029] A diaphragm valve durability testing device is used to test the durability of a diaphragm 110 in a diaphragm valve 100, comprising: a body 200, a simulation test fixture 300 and a testing fixture 400, wherein the body 200 comprises a first station 210 and a second station 220 which are arranged at intervals; the simulation test fixture 300 is located at the first station 210, and the simulation test fixture 300 is connected to the diaphragm valve 100 to control the opening and closing of the diaphragm 110 in the diaphragm valve 100; the testing fixture 400 is installed at the second station 220, and is connected to the simulation test fixture 300, and can be used to detect the air tightness of the diaphragm valve 100.

[0030] For details, please refer to Figure 1The machine body 200 includes a first station 210 and a second station 220 which are arranged at intervals. The first station 210 and the second station 220 are preferably arranged horizontally, but can also be arranged vertically. A simulation test fixture 300 is arranged in the first station 210. The simulation test fixture 300 is connected to the diaphragm valve 100 and is used to drive the opening and closing of the diaphragm 110 in the diaphragm valve 100. By arranging the simulation test fixture 300 located in the first station 210, while automatically controlling the opening and closing of the diaphragm valve 100, the opening and closing conditions of the diaphragm valve 100 can also be recorded, thereby avoiding the uncertainty and complexity of manual counting and improving the efficiency of the detection device. The testing tool 400 is arranged at the second station 220, and the testing tool 400 is connected to the simulation test tool 300. The simulation test tool 300 can control the opening and closing of the testing tool 400 while completing the control of the opening and closing of the diaphragm valve 100. When the diaphragm valve 100 completes the specified number of tests at the first station 210, the testing tool 400 is started, and the diaphragm valve 100 moves from the first station 210 to the second station 220 to complete the inspection of the diaphragm valve 100. The diaphragm valve 100 that has passed the inspection arrives at the first station 210 again from the second station 220 to continue the test until the durability performance test of the diaphragm valve 100 is completed.

[0031] Please refer to Figure 2 The simulation test tool 300 includes: a base 310, on which a plurality of mounting parts for mounting the diaphragm valve 100 are provided; a control component 320, which is connected to the diaphragm valve 100 and can synchronously control the opening and closing of the diaphragms 110 in the plurality of diaphragm valves 100.

[0032] Specifically, the simulation test tool 300 is used to simulate the daily use of the diaphragm valve 100, and the durability performance of the diaphragm valve 100 is tested by controlling the opening and closing of the diaphragm 110. By setting a base 310, and providing a plurality of mounting parts for installing the diaphragm valve 100 on the base 310, a plurality of diaphragm valves 100 can be installed on a base 310 at the same time, so as to test a plurality of diaphragm valves 100 at one time and improve the detection efficiency of the detection device; by setting a control component 320, the opening and closing state of the diaphragm 110 in the diaphragm valve 100 is controlled and adjusted, and the opening and closing times of the diaphragm valve 100 can be recorded. When the opening and closing times of the diaphragm 110 reach a certain number, the test of the diaphragm valve 100 is stopped, and the detection tool 400 connected thereto is started to complete the next step of detection.

[0033] Furthermore, the valve body control component 320 also includes at least one control module 321 and at least one relay 322, and the relay 322 is connected to the diaphragm valve 100. By providing the relay 322 and connecting the relay 322 to the execution end of the diaphragm valve 100, the control component 320 can control the opening and closing state of the diaphragm valve 100 and record the number of openings and closings.

[0034] Please refer to Figure 2 The control component 320 includes at least one switching power supply 323, which is installed on the base 310. The switching power supply 323 is detachably installed on the base 310 and is connected to the base 310 by bolts. In one embodiment, a power supply mounting seat is provided on the base 310, and the switching power supply 323 is installed in the power supply mounting seat; the switching power supply 323 is connected to control components such as a relay 322 to provide power for the relay 322.

[0035] The simulation test fixture 300 also includes: a connection component 330, the connection component 330 connects the diaphragm valve 100 and the control component 320 located on the base 310, and the control component 320 can synchronously control the opening and closing of multiple diaphragm valves 100 through the connection component 330. The diaphragm valve 100 generally controls the diaphragm 110 through the actuator end, and the actuator ends of multiple diaphragm valves 100 are connected as a whole by setting the connection component 330. The actuator end in this application is preferably a pneumatic actuator end, which is driven by a gas-driven actuator end; therefore, the connector in this application is preferably an air pipe, and multiple pneumatic actuator ends are connected through the air pipe. It can be imagined that when facing different actuator ends, the connector needs to be compatible with the actuator end.

[0036] The inspection tool 400 includes at least one helium inspection component 410. When the diaphragm valve 100 is located at the second station 220, the helium inspection component 410 is connected to the diaphragm valve 100. By providing the helium inspection tool, the diaphragm valve 100 can be inspected for internal and external leakage, so as to inspect the sealing performance of the diaphragm valve 100 after a certain number of openings and closings, so as to judge the durability of the diaphragm valve 100.

[0037] Please refer to Figure 1 The helium detection component 410 includes at least one accommodating chamber 411 , and the accommodating chamber 411 can be used to accommodate the simulation test tool 300 . The accommodating chamber 411 is provided to accommodate the diaphragm valve 100 .

[0038] Please refer to Figure 1The body 200 also includes a conveying component 230, which is connected to the simulation test tooling 300 and is at least partially located in the detection tooling 400; wherein, after the diaphragm valve 100 completes the simulation test at the first station 210, it can be transported from the first station 210 to the second station 220 for detection by the conveying component 230. By setting the conveying component 230, the diaphragm valve 100 can be moved to realize the transformation of the diaphragm valve 100 between the first station 210 and the second station 220.

[0039] Please refer to Figure 2 The simulation test fixture 300 also includes: an air supply component 340, which is connected to the diaphragm valve 100 and delivers high-pressure gas to the diaphragm valve 100 to simulate the use environment of the diaphragm valve 100. The air supply component 340 includes an air source and a power supply. The output end of the air source is connected to the inlet of the diaphragm valve 100 to provide a certain pressure for the diaphragm valve 100 to simulate the actual use. After passing through the diaphragm valve 100, the high-pressure gas is output from the outlet of the diaphragm valve 100 to complete the recycling of the gas.

[0040] Please refer to Figure 2 The simulation test fixture 300 also includes: a temperature measuring component 350, which is installed on the base 310 and is used to measure the temperature of the diaphragm valve 100. The diaphragm valve 100 is provided with a sealing ring for sealing the diaphragm 110. The reason why the diaphragm 110 is generally opened and closed once every 2 seconds in the existing diaphragm valve 100 test device is that the sealing ring is generally made of rubber material. When the movement speed of the diaphragm valve 100 is too fast, the temperature of the sealing part will rise quickly, thereby affecting the performance of the sealing ring, resulting in a decrease in the airtightness of the diaphragm valve 100. By setting up the temperature measurement component 350 and connecting the temperature measurement component 350 with the control component 320, the temperature measurement component 350 can monitor the temperature of the sealing ring in the diaphragm valve 100 in real time, and change the opening and closing speed of the diaphragm 110 in the diaphragm valve 100 according to the real-time temperature, so as to keep the opening and closing speed of the diaphragm 110 at a higher speed. Compared with the detection device in the prior art, the measurement efficiency of the diaphragm valve 100 durability test device can be greatly improved by setting up the temperature measurement component 350.
