It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1 and 2, the utility model provides a locking test tool for fixing and adjusting the position of a butterfly valve plate, which comprises an upper layer block body 1 and a lower layer block body 2, wherein the upper layer block body 1 and the lower layer block body 2 are both of a cylindrical structure with a groove on one side, and the opening of the groove 3 of the upper layer block body 1 and the opening of the lower layer block body 2 are respectively provided with a fastening device 4 for locking the groove 3; the two sides of the slot 3 of the upper layer block body 1 are respectively provided with an adjusting bolt 5, the upper layer block body 1 is connected with the lower layer block body 2 through the adjusting bolt 5, and the relative position between the upper layer block body 1 and the lower layer block body 2 is adjusted through the adjusting bolt 5.
In the embodiment, the parts to be tested corresponding to the test tool meet the requirements of description and operation chapters in CMM36-11-23-R12 and CRM36-11-23-R3 manuals on part shapes, sizes and data in test chapters.
In the embodiment, the test tool clamps the component to be fixed through a unilateral slotted structure, and locks the slot 3 by using a fastening device 4 such as a screw and the like to provide enough fixing force. The upper-layer block body 1 is used for fixing a shaft of the butterfly valve plate, the lower-layer block body 2 is used for fixing the valve flow shell, and the upper-layer block body 1 and the lower-layer block body 2 are fixed together by screwing two adjusting bolts 5, so that the butterfly valve plate is fixed and does not rotate relative to the shell. Simultaneously can unscrew adjusting bolt 5 back fine setting upper strata block 1 and the relative position between the block 2 of lower floor to change butterfly valve board's rotation angle, test once more, with the position of seeking the minimum internal leakage value valve board.
In this embodiment, the upper block 1 and the lower block 2 are both provided with an axial central through hole 6, the central through hole 6 is communicated with the slot 3, and the width of the central through hole 6 is greater than the width of the slot 3. In general, in order to provide enough fastening force, the width of the slot 3 is narrow, and the part cannot be clamped when the size is large, so that the central through hole 6 is adopted, so that the fastening device 4 can provide enough fastening force and meet the size requirement of the part.
In order to facilitate the adjustment of the relative position between the upper-layer block 1 and the lower-layer block 2 by the adjusting bolt 5, as shown in fig. 3, in the preferred embodiment, a sliding groove 7 is formed in the upper surface of the lower-layer block 2, a movable nut 8 corresponding to the adjusting bolt 5 is arranged in the sliding groove 7, and the movable nut 8 can slide in the sliding groove 7; and a limiting protrusion 9 is arranged on the sliding groove 7 to limit the axial movement of the movable nut 8.
