Accompanying drawing explanation
Fig. 1 is the structural representation of originally hydrostatic accurate hand-guided testing machine forward among a small circle.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
As shown in the embodiment shown in fig, this is hydrostatic accurate hand-guided testing machine among a small circle, comprise fixing frame plate 1, connection slide-bar 2, sliding clamp 3, promote screw mandrel 4, booster rod 5, described fixing frame plate 1 is two pieces, vertically staggered relatively, described connection slide-bar 2 number is four in the present embodiment, and be vertically connected between two fixing frame plates 1, described sliding clamp 3 is slidedly assemblied on the connection slide-bar 2 between described fixing frame plate 1; Described four connection slide-bars 2 assemble mutually respectively at four Angle Position of described sliding clamp 3, and described like this sliding clamp 3 runs more stable on described connection slide-bar 2.The rotatable assembling in one end of described sliding clamp 3 and described promotion screw mandrel 4, described sliding clamp 3 is only to the end axial limiting of described promotion screw mandrel 4.The other end of described promotion screw mandrel 4 is through a fixing frame plate 1, with promotion fixed block 6 Screw assembly be fixed on a fixing frame plate 1, the external part of described promotion screw mandrel 4 is equipped with and promotes handwheel 41, the axial location of described promotion handwheel 41 and the pivot joint of described promotion screw mandrel 4.
As shown in Figure 1, the inner side of another fixing frame plate 1 described is fixed with valve locating piece 7, valve 8 sealing to be detected is assemblied between described valve locating piece 7 and fixing frame plate 1, supercharging fixed block 9 is fixed with outside another fixing frame plate 1 described, one end of described booster rod 5 is fixedly equipped with supercharging handwheel 51, booster rod 5 one end of described assembling supercharging handwheel 51 is processed with screw structure, described booster rod 5 other end is smooth shaft, the screw portion of described booster rod 5 is connected with described supercharging fixed block 9 threaded screw rod, the smooth shaft of described booster rod 5 stretches into valve 8 inner chamber through described valve locating piece 7, between the smooth shaft of described booster rod 5 and valve 8, slipper seal is assembled, the assembling handwheel position, top of described valve 8 is connected with liquid feed device 10 and pressure test device 11.Described liquid feed device 10 is built with being used for the liquid of supercharging, and described proving installation 11 is mainly hydralic pressure gauge etc.The test point of described proving installation 11 and the intracavity inter-connection of valve to be tested 8.
