In the process of pulling out, because the split expansion sleeve is made of brass processing parts, the hardness is low, and both ends of the outer ring are provided with rounded corners, which can avoid scratch damage. The utility model can not only improve the disassembly efficiency, but also prevent the plug-in from being scratched and damaged, and has the advantages of safety and reliability.

Description

Hydraulic valve block plug-in removal tool

technical field

The utility model relates to a dismantling tool for a hydraulic valve group plug-in, in particular to a special tool for dismantling a hydraulic valve group plug-in in a hydropower station.

Background technique

When disassembling the hydraulic valve group plug-in in a hydropower station, it is difficult to disassemble the valve group plug-in from the valve seat using conventional tools, and the disassembly efficiency is low; The sealing effect of the plug-in is not ideal for safety. Therefore, existing tools for removing plug-ins of hydraulic valve groups have the problems of low disassembly efficiency, easy scratching and damage to plug-ins, and unsatisfactory safety.

Utility model content

The purpose of the utility model is to provide a hydraulic valve group plug-in removal tool. The utility model can not only improve the disassembly efficiency, but also prevent the plug-in from being scratched and damaged, and has the advantages of safety and reliability.

The technical scheme of the utility model: the plug-in removal tool for the hydraulic valve group includes a handle, and one end of the handle is connected to the split expansion sleeve bolt through a threaded hole; the split expansion sleeve bolt is provided with a split expansion sleeve compression nut, and the split expansion sleeve The right side of the compression nut is connected with a split expansion sleeve support, and the right side of the split expansion sleeve support is provided with a split expansion sleeve.

In the aforementioned hydraulic valve group plug-in removal tool, one end of the split expansion sleeve bolt is provided with a conical boss, and one end of the split expansion sleeve support is provided with a slope.

In the aforementioned hydraulic valve group plug-in removal tool, the split expansion sleeve is a brass processing part and there are two parts. Both ends have rounded corners.

Compared with the prior art, the utility model improves the plug-in removal tool for the hydraulic valve group. By rotating the split expansion sleeve to tighten the nut, the split expansion sleeve support moves along the split expansion sleeve bolts to the side of the boss. ;The split expansion sleeve is expanded outwards through the slope and the boss, and then the disassembly is completed by pulling the handle outward, which improves the disassembly efficiency. In the process of pulling out, because the split expansion sleeve is made of brass processing parts, the hardness is low, and both ends of the outer ring are provided with rounded corners, which can avoid scratch damage. Therefore, the utility model can not only improve the disassembly efficiency, but also prevent the insert from being scratched and damaged, and has the advantages of safety and reliability.

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a working principle diagram of the utility model.

The marks in the drawings are: 1-handle, 2-threaded hole, 3-split expansion sleeve bolt, 4-split expansion sleeve compression nut, 5-split expansion sleeve support, 6-split expansion sleeve , 7-boss, 8-slope, 9-plug, 10-hydraulic valve group.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the utility model.

Example. The plug-in removal tool for the hydraulic valve group is composed as shown in Figure 1, including a handle 1, one end of the handle 1 is connected to the split expansion sleeve bolt 3 through the threaded hole 2; the split expansion sleeve bolt 3 is provided with a split expansion sleeve compression nut 4. The right side of the split expansion sleeve compression nut 4 is connected with a split expansion sleeve support 5 , and the right side of the split expansion sleeve support 5 is provided with a split expansion sleeve 6 .

One end of the split expansion sleeve bolt 3 is provided with a conical boss 7, and one end of the split expansion sleeve support member 5 is provided with a slope 8; the split expansion sleeve 6 is a brass processing part and is provided with two , Both ends of the inner ring of the split expansion sleeve 6 are provided with slopes 8, and both ends of the outer ring of the split expansion sleeve 6 are provided with rounded corners.

The utility model is a combined tool. When using it, first press the handle 1, the split expansion sleeve bolt 3, the split expansion sleeve compression nut 4, the split expansion sleeve support member 5 and the split expansion sleeve 6 according to the diagram. As shown in 1, they are combined together, wherein the split expansion sleeve 6 is kept in a state of no stress; then, as shown in Figure 2, they are put into the insert 9 together, and then the split expansion sleeve compression nut 4 is tightened to make the split The expansion sleeve support 5 moves along the direction shown in Figure 2, and the split expansion sleeve 6 is squeezed by the split expansion sleeve support 5 and the boss 7 at the end of the split expansion sleeve bolt 3, and one end of the split expansion sleeve support 5 The slope surface 8 and the boss 7 are extruded with the slope surface 8 on the split expansion sleeve 6, so that the two split expansion sleeves 6 expand outward to tighten the inner wall of the insert 9; finally, along the direction shown in Figure 2 Pull the handle 1 in the opposite direction, and the insert 9 can be pulled out from the hydraulic valve block 10 . At the same time, in the process of pulling out, because the split expansion sleeve 6 is made of brass, its hardness is far lower than that of the insert 9, which can avoid scratching the insert 9 and the metal sealing surface on the insert 9, and the outer Both ends of the ring are rounded to further avoid scratch damage.
