SPECIFIC EMBODIMENT

[0022] The utility model makes further detailed explanation as follows:

[0023] As Figures 1 to 5 The utility model provides a kind of steel pipe welding ring water pressure experiment quick water filling device, including water tank 1, the top of water tank 1 is fixedly installed with water filling assembly 2, water filling assembly 2 includes frame body 21, frame body 21 is equipped with guide slot 22 in front and back two sides, cylinder 23 is fixedly installed in the left side of frame body 21, fixed rack 24 is fixedly installed in the right side of frame body 21 inside, sliding frame 25 is fixedly installed in the inside of frame body 21 of cylinder 23, fixed rack 24 and sliding frame 25 are respectively fixedly installed with shunt pipe one 26 and shunt pipe two 27, shunt pipe one 26 and shunt pipe two 27 are all fixedly installed with sealing sleeve 28 in the inside, valve 29 is arranged on the outside of shunt pipe one 26 and shunt pipe two 27, water tank 1's left and right sides are fixedly installed with the booster pump 210 respectively connected with shunt pipe one 26 and shunt pipe two 27.

[0024] Through sliding frame 25 along the inside of guide slot 22 sliding, steel pipe is extruded and sealed on the sealing sleeve 28 in the inside of shunt pipe one 26 and shunt pipe two 27, the water body in tank body 11 is extracted from two sides by the booster pump 210 of water tank 1 two sides and is injected into steel pipe from shunt pipe one 26 and shunt pipe two 27 from two sides, to improve water filling rate, can simultaneously detect multiple steel pipes, improve efficiency.

[0025] As Figure 4 And Figure 5 Water tank 1 includes tank body 11, opening 12 is formed in the top of tank body 11, clamping strip 13 is fixedly installed in the inside of opening 12, filter plate 14 is movably clamped on the top of clamping strip 13.

[0026] After completing experiment, water in steel pipe flows to filter plate 14, and the water body is returned to the inside of tank body 11 after filtering impurities through filter plate 14, to be reused, save water resources.

[0027] As Figure 3 Valve 29 is equidistantly arranged on the outside of shunt pipe one 26 and shunt pipe two 27.

[0028] Multiple branch pipes are arranged on shunt pipe one 26 and shunt pipe two 27 and cooperate with the use of valve 29, so that multiple steel pipes can be simultaneously detected.

[0029] As Figure 3 Pressure gauge 211 is equidistantly fixedly installed on the top of shunt pipe one 26.

[0030] The water pressure in steel pipe can be monitored by pressure gauge 211 on shunt pipe one 26 to control water pressure stable.

[0031] AsFigure 2 and Figure 3 As shown, the sliding frame 25 is movably engaged with the inner side of the guide groove 22.

[0032] The sliding frame 25 is locked in the guide groove 22, which can limit and guide the sliding frame 25.

[0033] like Figure 5 As shown, the filter plate 14 is inclined toward the fixing frame 24.

[0034] The water is collected by the inclined filter plate 14, so that impurities are filtered out and the water is returned to the tank 11 for recycling.

[0035] like Figure 4 As shown, the tank 11 is equipped with a water level observation strip 15, and a water pipe 16 is fixedly connected to the outside of the tank 11.

[0036] The water level inside the tank 11 can be viewed through the water level observation bar 15, and water can be drained or added to the tank 11 in conjunction with the water pipe 16.

[0037] like Figure 1 As shown, a support frame 4 is fixedly installed on the inner side of the water filling component 2.

[0038] It can be supported by placing the steel pipe on the support frame 4.

[0039] The working principle of the rapid water filling device for the hydrostatic test of the steel pipe weld ring is explained in detail below.

[0040] like Figures 1 to 5 As shown, by placing the steel pipe on the support frame 4 and pushing the sliding frame 25 along the inner side of the frame 21 by the control cylinder 23, the sliding frame 25 slides along the inner side of the guide groove 22 towards the fixed frame 24, so that one end of the steel pipe abuts against the sealing sleeve 28 inside the second diversion pipe 27, and pushes the other end of the steel pipe against the sealing sleeve 28 inside the first diversion pipe 26. The movement of the sliding frame 25 presses the steel pipe tightly against the sealing sleeve 28 to ensure a seal. The booster pumps 210 on both sides draw water from the tank 11 and send it into the first diversion pipe 26 and the second diversion pipe 27 respectively, and then inject it into the steel pipe. The pressure value is monitored by the pressure gauge 211 to conduct the experiment. After completion, the sliding frame 25 is reset to make the water in the steel pipe flow to the filter plate 14, and the water flows back into the interior of the tank 11 through the filter plate 14.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
