[0023] Reference Figure 1 , Figure 2 and Figure 3 A butterfly valve assembly and pressure testing auxiliary device includes a first support 110, a second support 120, and a support assembly 200. The first support 110 and the second support 120 are spaced apart. The support assembly 200 is located between the first support 110 and the second support 120 and is provided with a placement platform 210 for vertically placing the butterfly valve 1. A first pressure testing element 130 is provided on the side of the first support 110 facing the second support 120, and a second pressure testing element 140 is provided on the side of the second support 120 facing the first support 110. An actuator 111 is provided on the first support 110 to drive... Device 111 is driven to connect with the first test pressure member 130 and is used to drive the first test pressure member 130 to move relative to the second test pressure member 140, so that the first test pressure member 130 and the second test pressure member 140 can cooperate to clamp the butterfly valve 1 which is placed vertically on the placement platform 210. The first test pressure member 130 and the second test pressure member 140 are both provided with a test pressure chamber 101 for docking with the medium channel of the butterfly valve 1. The first test pressure member 130 and the second test pressure member 140 are both provided with a test pressure interface 102 that communicates with the test pressure chamber 101. The test pressure interface 102 is used to connect with external gas supply equipment and pressure measuring equipment.
[0024] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, in use, the butterfly valve 1 is placed vertically on the placement platform 210 and positioned between the first test pressure member 130 and the second test pressure member 140. Then, the driver 111 drives the first test pressure member 130 to move relative to the second test pressure member 140, so that the first test pressure member 130 and the second test pressure member 140 can cooperate to clamp the butterfly valve 1. This provides clamping and auxiliary support for the butterfly valve 1 placed vertically on the placement platform 210, facilitating the assembly of components such as the valve stem by workers, reducing the possibility of the butterfly valve 1 tipping over, and improving operational safety. After assembly, the test pressure interface 102 of the first test pressure member 130 can be connected to an external air supply device to perform the first test pressure. The test chamber 101 of the first test component 130 is pressurized, and the test port 102 of the second test component 140 can be connected to a pressure measuring device to measure the pressure of the test chamber 101 of the second test component 140. Alternatively, the test port 102 of the second test component 140 can be connected to an external air supply device to pressurize the test chamber 101 of the second test component 140. The test port 102 of the first test component 130 can be connected to a pressure measuring device to measure the pressure of the test chamber 101 of the first test component 130. This allows for testing of the sealing performance of the butterfly plate at the medium channel of the butterfly valve 1, avoiding the inconvenience of additionally transporting and transferring the butterfly valve 1 for testing, improving production efficiency, and facilitating production application.
[0025] In practical applications, the sealing performance of both sides of the butterfly valve 1 can be tested. For example, pressure can be supplied to the test chamber 101 of the first test pressure member 130 and the pressure of the test chamber 101 of the second test pressure member 140 can be tested first. Then, pressure can be supplied to the test chamber 101 of the second test pressure member 140 and the pressure of the test chamber 101 of the first test pressure member 130 can be tested. By testing the sealing performance of the butterfly valve 1 under pressure on both sides, the accuracy of the test can be ensured. Alternatively, two test ports 102 can be set for each test chamber 101. One port is connected to an external air supply device for pressure supply, and the other port is connected to a pressure measuring device. After the pressure supply is completed, the pressure is held for a preset time, and the pressure change is tested using the pressure measuring device to achieve the sealing performance test. The specific settings can be adjusted according to the actual use requirements.
[0026] In some embodiments, the first test pressure member 130 and the second test pressure member 140 are both provided with an annular groove 103 for accommodating the sealing ring. The annular groove 103 is arranged around the opening of the test pressure chamber 101 that connects with the medium channel of the butterfly valve 1.
[0027] Understandably, such as Figure 2 and Figure 3As shown, the opening of the test chamber 101 of the first test pressure component 130 faces to the right, for docking with the left side of the medium channel of the butterfly valve 1. The opening of the test chamber 101 of the second test pressure component 140 faces to the left, for docking with the right side of the medium channel of the butterfly valve 1. Both the right side of the first test pressure component 130 and the left side of the second test pressure component 140 are provided with annular grooves 103, which surround the opening of the test chamber 101. In use, a sealing ring is installed in the annular groove 103. The right side of the first test pressure component 130 abuts against the butterfly valve 1 and is sealed by the sealing ring on its right side. The left side of the second test pressure component 140 abuts against the butterfly valve 1 and is sealed by the sealing ring on its left side, ensuring a good sealing effect between the test chamber 101 and the medium channel, and ensuring the accuracy of subsequent sealing performance tests. In practical applications, multiple annular grooves 103 can be provided on each test pressure component, depending on the actual needs.
[0028] In some embodiments, the first test pressure component 130 can be disassembled and replaced relative to the first support 110, and the second test pressure component 140 can be disassembled and replaced relative to the second support 120. It is understood that by making the first test pressure component 130 and the second test pressure component 140 disassembled and replaceable, different sized test pressure components can be replaced according to the needs of different models of butterfly valves 1, meeting the assembly and testing requirements of different models of butterfly valves 1 and improving the adaptability of the device. In practical applications, the specific assembly and disassembly methods of the first test pressure component 130 and the second test pressure component 140 can be set according to actual usage needs, and will not be described in detail here, but will be explained in detail below.
[0029] In some embodiments, a guide rod 150 is provided between the first support 110 and the second support 120, and the first test member 130 and the second test member 140 both cooperate with the guide rod 150 so that they can move along the guide rod 150.
[0030] Understandably, such as Figure 1 and Figure 2 As shown, the first support 110 and the second support 120 are spaced apart in the left-right direction, and the guide rod 150 extends in the left-right direction. The first test pressure member 130 and the second test pressure member 140 both cooperate with the guide rod 150. By setting the guide rod 150, the relative movement of the first test pressure member 130 and the second test pressure member 140 can be guided, improving reliability. In practical applications, the second test pressure member 140 can also be fixed, or the second support 120 can also be equipped with a driver 111, using two drivers 111 to drive the first test pressure member 130 and the second test pressure member 140 to move relative to each other, which can be set according to the actual needs of use.
[0031] In some embodiments, the first support 110 and the second support 120 are spaced apart in the left-right direction, and two guide rods 150 are provided and spaced apart in the front-back direction on both sides of the first test member 130. It is understood that, as Figure 1 and Figure 2 As shown, two guide rods 150 are provided and are spaced apart along the front and rear sides of the first test pressure member 130. The front and rear sides of the first test pressure member 130 cooperate with the two guide rods 150 respectively, and the front and rear sides of the second test pressure member 140 cooperate with the two guide rods 150 respectively, which restricts the front and rear positions of the first test pressure member 130 and the second test pressure member 140 and improves the reliability of the relative movement between the two test pressure members.
[0032] In some embodiments, ear plates 160 are provided on the front and rear sides of the first test pressure member 130 and the front and rear sides of the second test pressure member 140. The ear plates 160 are provided with notches 104 with downward openings, and the guide rod 150 can enter the notches 104 from the lower opening of the notches 104.
[0033] Understandably, such as Figure 1 and Figure 2 As shown, ear plates 160 are provided on the front and rear sides of the first test pressure piece 130 and the front and rear sides of the second test pressure piece 140. Each ear plate 160 has a downward-facing notch 104, which is roughly inverted "U" shaped. In use, the guide rod 150 can enter the notch 104 through the lower opening, allowing the first test pressure piece 130 and the second test pressure piece 140 to be mounted on the two guide rods 150 via the corresponding ear plates 160. The structure is simple and facilitates the assembly, disassembly, and replacement of the two test pressure pieces. In practical applications, the fit between the test pressure piece and the guide rod 150 can also be a shaft-hole fit or a slide rail-slider fit, which can be set according to the actual needs of use.
[0034] In some embodiments, two ear plates 160 are provided at intervals along the left-right direction on the front and rear sides of the first test pressure member 130 and the front and rear sides of the second test pressure member 140. It is understood that, as Figure 1 and Figure 2 As shown, the two ear plates 160 on the front side and the two ear plates 160 on the rear side of the first test pressure piece 130 are spaced apart in the left-right direction. The two ear plates 160 on the front side and the two ear plates 160 on the rear side of the second test pressure piece 140 are also spaced apart in the left-right direction. The first test pressure piece 130 and the second test pressure piece 140 are respectively engaged with the two guide rods 150 on the front and rear sides through the four ear plates 160, so that the test pressure piece and the guide rod have good engagement stability and are easy to use.
[0035] In some embodiments, the output end of the driver 111 is provided with a threaded part 112, and the output end of the driver 111 abuts against the first test pressure member 130 and is connected to the ear plate 160 on the first test pressure member 130 through the threaded part 112.
[0036] Understandably, such as Figure 1 and Figure 2 As shown, the output end of the driver 111 is provided with connecting ears 113 on both the front and rear sides. Each connecting ear 113 has a threaded component 112, which connects to the corresponding ear plate 160 on the first test pressure member 130. This allows the output end of the driver 111 to abut against the first test pressure member 130. This connection method is simple, stable, and reliable, facilitating the driver 111 to move the first test pressure member 130 and simplifying the assembly and disassembly of the first test pressure member 130 and the driver 111, making it convenient to use. In practical applications, the driver 111 and the first test pressure member 130 can also be detachably connected via a pin structure or a snap-fit structure, depending on the specific application requirements.
[0037] In some embodiments, both ends of the guide rod 150 are provided with threaded structures, and the two ends of the guide rod 150 are respectively fixedly connected to the first support 110 and the second support 120 through the threaded structures. It is understood that, as... Figure 1 , Figure 2 and Figure 3 As shown, both ends of the guide rod 150 are provided with threaded structures. The left and right ends of the guide rod 150 are fixedly connected to the first support 110 and the second support 120 respectively through the threaded structures. Its structure is simple and easy to use.
[0038] In some embodiments, the support assembly 200 can drive the placement platform 210 to move up and down. It is understood that by enabling the placement platform 210 to move up and down, the placement requirements of different models of butterfly valves 1 can be met, improving the adaptability of the device. In practical applications, the support assembly 200 can drive the placement platform 210 to move up and down by setting an actuator, such as using a jack, or by manually adjusting the placement platform 210; the specific settings can be configured according to actual usage needs.
[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
