Background technology
ISO2531-98 and GB13295-91 regulation magnesium iron cast tube must carry out the hydraulic testing by the pressure of stipulating by root.The hydrostatic testing machine of relevant manufacturer use respectively has its characteristics both at home and abroad, but the most manufacturers of heavy caliber magnesium iron pipe fitting are adopted manual structure for pressure test, and production efficiency is very low, and so both inconvenient, dangerous again.
Summary of the invention:
In order to overcome the shortcoming of prior art, the present invention provides a kind of frame-type heavy caliber pipe fitting hydrostatic testing machine, and its efficient is high, and is safe and reliable.
The present invention solves the technical scheme that its technical matters takes: fixing respectively left side oil cylinder, left side hydraulic control water valve, right side oil cylinder, right side hydraulic control water valve and master cylinder, main hydraulic control water valve on Zuo Bi, right wall and the upper wall of door type framework; Fixed main shaft on the piston rod of said left side oil cylinder; The center of main shaft is connected fixing with pressing plate through hemisphere groove, hemisphere piece, fixing adjustment plate is uniformly distributed with spring stack on the adjustment plate on the outer wall of main shaft; All spring stacks and described pressing plate are hinged; Sealing and fixing pressure ring on the right side of pressing plate, fixed seal ring on the right side of pressure ring, described left side hydraulic control water valve communicates with described pressure ring inner wall sealing through the left side pipeline; Have respectively on the piston rod of described right side oil cylinder and master cylinder and the identical structure of described left side oil cylinder piston bar front end.
The present invention can be to various pipe fitting (threeways; Four-way) carries out hydrostatic test; Can satisfy in enormous quantities, the needs of the hydraulic testing of the pipe fitting that the specification span is big are according to producing the different of pipe fitting specification and pressure; Fast changeable frock and Adjustment System pressure are suitable for various pipe fitting pressure testings up to specification and produce.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a front view of the present invention;
Fig. 2 is the A place enlarged drawing among Fig. 1 of the present invention;
Fig. 3 is the B place enlarged drawing among Fig. 1 of the present invention.
Embodiment
As shown in Figure 1, fixing respectively left side oil cylinder 2, left side hydraulic control water valve 3, right side oil cylinder 8, right side hydraulic control water valve 7 and master cylinder 6, main hydraulic control water valve 5 on Zuo Bi, right wall and the upper wall of door type framework 1.
As shown in Figure 2, fixed main shaft 13 on the piston rod of said left side oil cylinder 2, the center of main shaft 13 is connected with pressing plate 16 through hemisphere groove, hemisphere piece 19, and hemisphere piece 19 is fixing with pressing plate 16.Fixing adjustment plate 15 is uniformly distributed with spring stack 14 on the adjustment plate 15 on the outer wall of main shaft 13, and all spring stack 14 and described pressing plate 16 are hinged.Sealing and fixing pressure ring 17 on the right side of pressing plate 16, fixed seal ring 18 on the right side of pressure ring 17.
The structure of the piston rod front end of described right side oil cylinder 8 and master cylinder 6 is identical with left side oil cylinder 2.
Walking about the main shaft 13 of said left side oil cylinder 2 and right side oil cylinder 8 is sitting on the track 12,24 through support 20,22, castor 21,23 respectively is as the supplemental support of main shaft 13.
Described left side hydraulic control water valve 3 communicates with described pressure ring 17 inner wall sealings through left side pipeline 4.Described right side hydraulic control water valve 7 communicates with the pressure ring sealing of right side oil cylinder 8.Described main hydraulic control water valve 5 communicates with the pressure ring sealing of described master cylinder 6.
There is the dolly 10 that can place pipe fitting 11 below of said master cylinder 6, and dolly 10 is sitting on the guide rail 27 through spring(-supported) mount 25, wheel 26, and guide rail 27 is fixed with ground.
Stationary work-table 9 on the ground of said dolly 10 master cylinders 6 belows, gapped between worktable 9 and the dolly 10, make things convenient for dolly 10 to move.When master cylinder 6 pressed down, dolly 10 was sitting on the worktable 9, steadily.
During use, pipe fitting 11 is placed on the dolly, the pipe fitting end opening seals, and makes highly that with the cushion block adjustment pipe fitting horizontal interface is concentric with left and right side oil cylinder 2,8 when working.Dolly is transported to a type framework 1 time, and master cylinder 6 and left and right side oil cylinder 2,8 compress pipe fitting 11 sealings.Start the low pressure water system water filling, behind main hydraulic control water valve 5 backwater in master cylinder 6 upper ends, start high pressure water system to desired test pressure.The pressurize certain hour, slowly release.Discharge water, accomplish a hydraulic testing process.
