Fig. 2 is the partial structurtes schematic diagram with Valve contacting portion in this hydraulic dynamometer flange fastener.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
As shown in embodiment in Fig. 1 and Fig. 2, this valve hydrostatic tester fastener, it comprises fixing frame plate 1, connects slide-bar 2, sliding clamp 3, and described fixing frame plate 1 is two pieces, vertically staggered relatively, the bottom of described two pieces of fixing frame plates 1 uses transverse slat to be connected and fixed and is integrated.Described connection slide-bar 2 number is two or more, 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; Main rigging position height in the middle of it usually between 1.2 ~ 1.8 meters, assembling when facilitating workman to use.Described sliding clamp 3 is connected with the reducing motor 5 be fixed on one piece of fixing frame plate 1 by screw structure 4, the output shaft of reducing motor 5 and drive lead screw pivot joint.Fix described in another block to be equipped with inside frame plate 1 and be fixedly connected with block 6, be connected with inside described sliding clamp 3 and compress contiguous block 7; Described be fixedly connected with block 6, compress contiguous block 7 be tightly connected by sealing gasket with valve 8 liang of end flanges respectively.Be fixedly connected with block 6 described in described valve 8 to be detected passes through, compression contiguous block 7 is connected with testing hydraulic pipeline.Described testing hydraulic pipeline mainly comprises the equipment that some provide highly pressurised liquid in described valve 8 to be detected, and some check the hydraulic pressure display device that described valve 8 internal pressure changes.Be fixedly connected with block 6 in the apparatus, compression contiguous block 7 all can be used for being connected with pressure-display device.
This hydraulic dynamometer flange fastener belongs to a part for whole hydraulic dynamometer, and hydraulic pressure tester is mainly used for carrying out fitting tight test to hydraulic valve.The effect of this device is mainly used for carrying out fastening device to valve 8 when carrying out the hydrostatic test of valve.This device in use, valve 8 to be tested is assemblied between one piece of described fixing frame plate 1 and sliding clamp 3, described sliding clamp 3 can slide on described connection slide-bar 2, first sliding clamp 3 can be adjusted to opposite side at valve 8 to be tested when assembling like this, being fixedly connected with on block 6 described in valve 8 is fixed on; Then use reducing motor 5 to promote sliding clamp 3 by screw structure 4, compression contiguous block 7 is pressed on valve 8 flange.This connected mode valve 8 has enough operating spaces when assembling, and when not changing any part, this device just can facilitate the valve of the various length of test set-up.
The compression contiguous block 7 of this device is connected by buffer structure with between described sliding clamp 3 simultaneously, described compression contiguous block 7 is increased gradually to the contact that described valve 8 flange applies, and this contact to control.
Specifically, as shown in Figure 2, described compression contiguous block 7 is fixed on slide head 9, and described slide head 9 is slidably assemblied on the projecting shaft 10 that is vertically fixed on inside described sliding clamp 3, and the inner side of described slide head 9 is also connected with sliding clamp 3 by uniform stage clip 11.Described stage clip 11 is when compressing contiguous block 7 and not compressing described valve 8, be in free state, when reducing motor 5 drives described sliding clamp 3 to compress on valve 8 flange by screw body 4, first described compression contiguous block 7 contacts with described valve 8 right flange, halt, along with the continuation of reducing motor 5 drives, described projecting shaft 10 moves on along the axis hole on described slide head 9, is compressed gradually by stage clip 11; Described like this compression contiguous block 7 increases gradually to the contact that described valve 8 flange applies; Wherein said stage clip 11 pairs of slide heads 9 are directly proportional to the decrement of stage clip 11 together with the power compressing contiguous block 7 applying.Such people just can by realizing the decrement controlling stage clip 11, to the control of valve 8 two ends sealing dynamics, tester can being facilitated to detect the valve seal under concrete sealing dynamics.
As depicted in figs. 1 and 2, described projecting shaft 10 coaxially assembles with the drive lead screw of described screw structure 4.The power that described like this screw structure 4 applies just can act directly on the axis of screw mandrel, be applied directly to slide head 9 by described projecting shaft 10 and stage clip 11 and compress on contiguous block 7, then be applied directly on the flange of described valve 8, make the stressed more balanced of Whole Equipment, described sliding clamp 3 is not turned round to power when sliding, and friction force is less.
As shown in Figure 2, the duct being designed with and running through front and back and be communicated with described valve 8 is fixedly connected with in block 6 described in.The duct be communicated with described valve 8 is designed with in described compression contiguous block 7.The cavity of described like this valve 8 inside can be directly connected with fluid pressure line by these ducts.Also cut-in pressure checkout equipment can be carried out by this duct.
