During use, stopcock lower end is supported on the supporting plate, and the lower end of stopcock spool communicates with the oil-out of the vertical section of oil hole, by hydraulic control oil, piston is moved up again, thus head on supporting component by piston and move up, until the upper port of stopcock and the lower face of top board are adjacent to; Finally, to the oil hole oiling of back up pad, and by the bottom injection pressure oil of this oil hole to stopcock spool, at this moment observed by the viewport of top board, if the top observing stopcock spool has pressure oil to ooze out, then stopcock is defective, otherwise qualified.
Adopt above technical scheme, the present invention has abandoned existing pipe adapter in the art, so just need not remove connecting pipe joint arduously, the substitute is by back up pad and top board by two of stopcock port sealings, then to the oil hole injection pressure oil in back up pad, back up pad is both as support member, again as oil circuit element, and the structure of supporting component is simple, intensity is high, not easily clamping stagnation occurs.
For the ease of implementing, the upper and lower port of described cylinder sleeve inserts in the groove on base plate and intermediate plate respective panels face respectively.
Beneficial effect: the present invention has abandoned existing pipe adapter in the art, so just need not remove connecting pipe joint arduously, the substitute is two of stopcock port sealings by back up pad and top board, again to the oil hole injection pressure oil in back up pad, back up pad is both as support member, and again as oil circuit element, and the structure of supporting component is simple, intensity is high, not easily clamping stagnation occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of pressure testing machine, is formed primarily of base plate 1, intermediate plate 2, cylinder sleeve 3, screw 4, piston 5, top board 6 and supporting component.Wherein, have one piece of intermediate plate 2 directly over base plate 1 side by side, be fixed with a cylinder sleeve 3 between this two boards, the upper port of this cylinder sleeve 3 and lower port are inserted in the groove on base plate 1 and intermediate plate 2 respective panels face respectively, and are close to the respective plate face of respective panels.Further, together with base plate 1 and intermediate plate 2 are strained by one group of screw vertically arranged 4, the number of this screw 4 adjusts accordingly as required.Described cylinder sleeve 3 built with a piston 5, the via hole motive seal on this piston 5 upper end and described intermediate plate 2, and the piston body 5a of piston 5 middle and lower part and the motive seal of cylinder sleeve 3 inwall.Further, the upper end of cylinder sleeve 3 and bottom are respectively provided with an oil supply hole (not shown in FIG.), and by these two oil supply holes respectively to oiling in the cylinder sleeve 3 of piston body 5a upper and lower sides, so that control piston 5 moves up and down.Described top board 6 also comes directly over intermediate plate 2, this two boards is connected by one group of screw rod vertically arranged 7, and the screw rod 7 of top board 6 and intermediate plate 2 upper and lower is all set with set nut 8, this syndeton is adopted not only to draw materials conveniently, easy to implement, and connect firm, the spacing between top board 6 and intermediate plate 2 can also be adjusted according to actual needs.In addition, the center of top board 6 vertically has a viewport 6a.
