[0022] The following describes the invention of the present invention in detail by way of examples in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Example

[0023] like Figures 1 to 2 As shown, the utility model discloses a glass fiber reinforced plastic pipe fitting pressure testing device, including a test frame 1, wherein a bracket 2 is provided inside the test frame 1, wherein the bracket 2 can be adjusted in height by a hydraulic cylinder, and a water storage tank 3 is provided at the bottom of the bracket 2; four screw rods 4 are telescopically connected to the test frame 1, and a pull rod 5 is sleeved inside each of the four screw rods 4. One end of the pull rod 5 is bolted to a plug 1 6, and the other end of the pull rod 5 is connected to the piston rod of a cylinder 7, and the cylinder 7 is fixedly connected to one end of the screw rod 4, and the other end of the screw 4 is bolted to a plug 2 8. The plug 1 6 is located outside the plug 2 8, and a seal 9 is provided between the plug 1 6 and the plug 2 8, and the seal 9 is a rubber ring. By providing a detachable plug 1 6 and plug 2 8, it is convenient to replace the plugs according to pipe fittings of different diameters. During sealing, the cylinder 7 contracts and drives the pull rod 5 to move, causing the plug 1 6 to move toward the plug 2 8, thereby squeezing the rubber ring to cause deformation and realize sealing of the pipe port.

[0024] Furthermore, in this embodiment, two of the four screws 4 are horizontally and symmetrically arranged on either side of the lower end of the detection frame 1, one is vertically arranged at the top of the detection frame 1, and one is arranged obliquely between one of the horizontal screws 4 and the vertical screw 4. Both the horizontal and vertical screws 4 are threadedly connected to the detection frame 1 and are driven to extend and retract by a power mechanism, while the oblique screw 4 is connected to the detection frame 1 via an angle adjustment mechanism. The positional distribution of the four screws 4 in this embodiment enables hydraulic testing of straight pipes, curved pipes, and tee pipe fittings.

[0025] Furthermore, in this embodiment, a water inlet is provided on the plug 6 arranged horizontally at the lower end of the detection frame 1, and a discharge port is provided on the plug 6 arranged obliquely and vertically at the upper end of the detection frame 1, and a valve is provided on the discharge port.

[0026] The angle adjustment mechanism includes an adjustment plate 10, which is mounted on the detection frame 1. An angle adjustment motor 11 is mounted on one side of the adjustment plate 10. A gear 12 (not shown) is fixedly connected to the output shaft of the angle adjustment motor 11. The gear 12 meshes with a rack 13 on the detection frame 1. Limit blocks 14 are provided at both ends of the rack 13. An inclined screw 4 is threadedly connected to the adjustment plate 10 and is driven to extend and retract by a power mechanism. The power mechanism uses a motor and a gear. The motor drives the gear to rotate, and the gear meshes with the threads on the screw 4. The angle adjustment mechanism facilitates the testing of bends at angles of 60°, 45°, 30°, and 22.5°, and is highly practical. During angle adjustment, the angle adjustment motor 11 drives the gear 12 to move on the rack 13, thereby driving the adjustment plate 10 and the screw 4 to move, achieving position adjustment.

[0027] It also includes a control panel 15 and a booster pump 16. The control panel 15 is located on one side of the detection frame 1 and is used to control the operation of the power mechanism, the angle adjustment motor 11 and the booster pump 16. The booster pump 16 is connected to the water inlet on the plug 6 through a high-pressure pipe.

[0028] Working principle: When in use, place the pipe fitting on the bracket 2, tie it up and fix it, and adjust the horizontal height of the pipe fitting by the hydraulic cylinder at the bottom of the bracket 2; adjust the extension and contraction of the screw rod 4 by the power mechanism until the sealing plug is pushed into the pipe fitting port; then the cylinder 7 contracts to drive the pull rod 5 to move, so that the plug 1 6 moves toward the plug 2 8, and then squeezes the rubber ring to cause deformation, so as to achieve sealing of the pipe fitting port; after sealing, the pressure test can be carried out, and the booster pump 16 is started to inject water into the pipe fitting, and the pressure is stabilized after reaching the target pressure; after stabilizing the pressure for a period of time, the water in the pipe fitting is discharged into the water storage tank 3 through the discharge port.
