[0002] Copper pipe fittings refer to various fittings used for connecting, supporting and changing the direction of copper pipes, and are widely used in fields such as heating, ventilation and air conditioning, water supply and drainage, and gas supply. Copper pipe fittings have good thermal conductivity, corrosion resistance and mechanical strength. The hydraulic pressure device of a copper pipe fitting hydraulic press is mainly used for hydraulic pressure testing of copper pipe fittings to detect their sealing performance and pressure-bearing capacity.
[0003] In the traditional hydraulic pressure device of a copper pipe fitting hydraulic press, there is a problem that it cannot adapt to copper pipe fittings with different diameters. The traditional hydraulic pressure device of a copper pipe fitting hydraulic press can only fix and test copper pipe fittings of one size, which has certain limitations. When it is necessary to test copper pipe fittings of different sizes, different devices need to be replaced, and the operation is cumbersome. For smaller or larger pipe fittings, if the fixture cannot effectively adapt, the clamping force may be insufficient, resulting in the displacement or falling off of the pipe fittings during the test, thus affecting the test results.

The support frame 200 is fixedly connected to the top of the water tank 100; the sliding plate 300 is slidably connected to the inside of the support frame 200; the clamping assembly includes two fixed frames 401, both of the two fixed frames 401 are fixedly connected to the top of the sliding plate 300, a bidirectional lead screw 402 is rotatably connected to the inside of the fixed frame 401, a clamping block 403 is also slidably connected to the inside of the fixed frame 401, and the threads at both ends of the bidirectional lead screw 402 are threadedly connected to the inside of the clamping block 403. A first turntable 404 is provided at one end of the bidirectional lead screw 402. A water pressure assembly for performing a water pressure test on the copper pipe fitting is provided inside the water tank 100. By rotating the first turntable 404, the bidirectional lead screw 402 is driven to rotate, thereby driving the two clamping blocks 403 to approach or move away from each other inside the fixed frame 401.
[0027] In one embodiment, as Figure 1 and Figure 2 shown, the water pressure assembly includes a water pump 501. The water pump 501 is provided inside the water tank 100. A water outlet pipe 502 is provided at the output end of the water pump 501, and a spray head 503 is provided at the other end of the water outlet pipe 502. By starting the water pump 501, the water inside the water tank 100 is pumped from the input end to the output end, and thus the water is conveyed to the spray head 503 through the water outlet pipe 502.
[0028] In one embodiment, as Figure 1 、 Figure 2 and Figure 3As shown, a moving component for moving the sliding plate 300 is provided inside the support frame 200. The moving component includes a threaded rod 601 which is rotatably connected inside the support frame 200 and is threadedly connected inside the sliding plate 300. A second turntable 602 is provided at one end of the threaded rod 601. By rotating the second turntable 602, the threaded rod 601 is driven to rotate, thereby driving the sliding plate 300 to slide inside the support frame 200.
[0029] In one embodiment, as Figure 1 and Figure 2 shown, the water spray head 503 is conical, a rubber gasket is attached to the surface of the water spray head 503, and the diameter of the end of the water spray head 503 away from the water outlet pipe 502 is smaller than the diameter of the end close to the water outlet pipe 502, so that it can adapt to copper pipe fittings of different calibers.
[0030] In one embodiment, as Figure 1 and Figure 2 shown, a solenoid valve 700 is provided on the water outlet pipe 502 to control the size of the water flow.
[0031] In one embodiment, as Figure 1 and Figure 2 shown, baffles 800 are provided around the top of the water tank 100 to prevent water from flowing away from the top of the water tank 100.
[0032] In one embodiment, as Figure 1 and Figure 2 shown, a plurality of drain holes 900 are further opened on the top of the water tank 100 to enable the water after the test to flow back into the water tank 100 again.
[0033] In one embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, diamond-shaped notches are provided on a plurality of the clamping blocks 403, and protective pads are provided on the diamond-shaped notches, so that copper pipe fittings of different sizes can be clamped and the copper pipe fittings can be prevented from loosening during the test.
[0034] The above embodiment discloses a water pressure device for a copper pipe fitting hydraulic press. Among them, by rotating the first turntable 404, it drives the bidirectional lead screw 402 to rotate, thereby driving the two clamping blocks 403 to move away from each other inside the fixed frame 401. Subsequently, one end of the copper pipe fitting to be subjected to the water pressure test is sealed, and then the copper pipe fitting is placed between the clamping blocks 403. Then, the first turntable 404 is rotated again to drive the two clamping blocks 403 to approach each other inside the fixed frame 401, thereby clamping and fixing the copper pipe fitting. Then, the second turntable 602 is rotated to drive the threaded rod 601 to rotate, thereby driving the sliding plate 300 to slide inside the support frame 200, so as to drive the copper pipe fitting to be tested closer to the water spray head 503. As the copper pipe fitting gets closer and closer, finally the water spray head 503 will reach inside the copper pipe fitting, and the water spray head 503 will fit with the copper pipe fitting to prevent leakage. Then, the water pump 501 is started to pump the water inside the water tank 100 from the input end to the output end through the water outlet pipe 502 and deliver it to the water spray head 503. Then, the water spray head 503 sprays water inside the copper pipe fitting. Finally, the copper pipe fitting is filled with water, thereby testing the copper pipe fitting. After the test is completed, the second turntable 602 is rotated again to drive the threaded rod 601 to rotate, thereby driving the sliding plate 300 and the copper pipe fitting away from the water spray head 503. Then, the water inside the copper pipe fitting will flow out and flow into the water tank 100 through the drain hole 900 opened at the top of the water tank 100, which can achieve the effect of saving. The baffles 800 around the water tank 100 can prevent the water from flowing out of the water tank 100 from the four sides of the top of the water tank 100.
[0035] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
