Embodiment Construction

[0022] The three-way hydraulic test device consists of a bottom plate 1, an upper top plate 6, a left plate 3, a right plate 9, a head end block 4, a sliding block 13, an end block 10, a first threaded ejector rod 7, Second threaded push rod 15, T-shaped threaded push rod 18. The bottom ends of the left side plate 3 and the right side plate 9 are fixedly connected to the left and right ends of the base plate 1 respectively, and the upper top plate 6 is fixedly connected to the tops of the left side plate 3 and the right side plate 9 . The bottom four corners of the bottom plate 1 are provided with supporting bases 2 . Bottom plate 1 is provided with two guide rails 19, the bottom surface of sliding block 13 and end block 10 is connected with roller 17, and its roller 17 is installed on the guide rail 19 of base plate 1, makes slide block 13 and end block 10 along guide rail 19 move. The first threaded mandrel 7 and the second threaded mandrel 15 are two groups, and the six s...

Abstract

The invention relates to a three-way element group hydraulic test device and a relative method, wherein upper and lower ends of a left side plate and a right side plate are respectively fixed with an upper lift plate and a bottom plate, the bottom plate is arranged with a track, while a sliding block can move along the bottom plate. A plurality of screw lift rod groups connect two screw lift rods in preset distance with the upper top plate and the bottom plate via screws, a T-type screw lift rod is connected with the right side plate via screw. The three-way group is clamped and positioned via rolling a rolling wheel and rotating screw lift rod. And the test method comprises that adjusting the height of the screw lift rods on the bottom plate, according to the size of the three-way element, arranging the grouped three-way element on the screw lift rods, using the screw lift rods on the upper lift plate to press the three-way element, using the T-type screw lift rod on the right side plate to clamp the three-way element after finding the position of the three-way element, using a hydraulic pump to increase pressure via preset pressure to process test. The invention has the advantages that the invention can process group hydraulic test of the three-way element in final product state, with simple detachment and installment of work-piece, reduced labor strength, shortened period and saved material.

Description

technical field [0001] The invention relates to a group hydraulic test method, in particular to a group hydraulic test device and method for three-way components. Background technique [0002] Equal-diameter tee joints are often used in ship piping accessories. Due to the special requirements of the working environment, they are often made of Ocr18Ni10Ti stainless steel. Due to the difficulty in die forging of stainless steel materials, the shape can only be obtained by machining the square blank. After the finished product is machined, its inspection requires not only the surface magnetic particle flaw detection, but also a 24Mpa water pressure test. In order to meet the requirements of the test, the traditional method is that during machining, the three end faces of the three-way parts are left with machining allowances and turned into threaded forms (as shown in Figure 1), and the three-way components are threaded to each other so that Perform hydraulic tests in groups....
