Description

Disassembly tooling for valve sleeve and cartridge valve block

technical field

The utility model relates to a dismantling tool for precision parts, in particular to a dismantling tool for a valve sleeve and a cartridge valve block.

Background technique

The rapid development of the country is inseparable from the support of the machinery industry. Among them, hydraulic technology plays a huge role in the fields of industrial machinery, engineering machinery, aerospace, marine development engineering, etc., and cartridge valves are very critical hydraulic components. For traditional cartridge valves, especially one-piece cartridge valves where the valve sleeve is connected to the cover plate, during the process of detaching the valve sleeve from the cartridge valve block, due to the large deformation of the sealing ring or the matching gap between the valve sleeve and the insertion hole It is very difficult to disassemble due to reasons such as being too small, which not only wastes manpower and material resources, but also causes scratches to varying degrees on the surface of the cartridge valve cover plate and the cartridge valve block due to improper disassembly, affecting the normal use of the cartridge valve and causing economic losses. .

Utility model content

The purpose of the utility model is to solve the above-mentioned problems existing in the prior art, and to provide a simple and reliable valve sleeve and cartridge valve block disassembly tool that can improve product disassembly and maintenance efficiency.

The purpose of this utility model is achieved by the following technical solutions: a valve sleeve and cartridge valve block disassembly tooling, mainly including: pilot valve 1, stop screw 2, hexagon socket head bolt 3, cover plate 4, insert Install the valve block 5, the first seal ring 6, the valve sleeve 7 and the second seal ring 8; the pilot valve 1, the cover plate 4, the valve sleeve 7, the first seal ring 6 and the second seal ring 8 are installed after assembly Inserted into the plug-in valve block 5, the valve sleeve 7 and the insertion hole 51 of the plug-in valve block 5 are clearance fit, and the radial seal is realized by the first sealing ring 6 and the second sealing ring 8, wherein the cover plate 4 There are four bolt holes 41 arranged evenly. The hexagon socket head bolts 3 pass through the bolt holes 41 and are connected with the cartridge valve block 5 so that the lower end surface of the cover plate 4 is in close contact with the upper end surface of the cartridge valve block 5 .

Preferably, the cover plate 4 is provided with a stop screw mounting hole 42, which is provided with an internal thread 421 close to the surface of the cover plate 4, and the inside is a light hole 422, the axis is perpendicular to the surface of the cover plate 4, and is aligned with the surface of the cover plate 4. There is a certain distance from the axis of the bolt hole 41, which is to ensure that the stop screw 2 is placed on the hexagon socket head bolt 3 after installation, and there is a small gap between the upper surface of the hexagon socket head bolt 3 and does not affect the inner hexagon Use a wrench to remove hexagon socket head cap bolts 3 as the standard, and the number of mounting holes is 2, which are arranged diagonally.

Preferably, the stop screw 2 is installed in the stop screw installation hole 42 , the tail is provided with an external thread 22 , the head is a polished rod 23 , and the end face of the tail is provided with a slot 21 .

The beneficial effects of the utility model are: the utility model utilizes two oppositely arranged stop bolts 2 to limit the axial movement of the hexagon socket head bolt 3 relative to the cover plate 4, and finally achieves the same time when the socket socket head bolt 3 is loosened. The separation of the valve sleeve 7 and the cartridge valve block 5 avoids the jamming phenomenon of the valve sleeve 7 and the insertion hole 51 caused by uneven application of force during the disassembly process of the valve sleeve 7 and the cartridge valve block 5, which is simple and labor-saving, and can The efficiency of disassembly and maintenance is improved, and the cartridge valve and the cartridge valve block 5 will not be damaged.

Detailed ways

Below in conjunction with specific examples, set forth the specific implementation manner of the present utility model.

Referring to Figure 1 to Figure 2, a valve sleeve and cartridge valve block disassembly tooling, the installation process is as follows: first, the pilot valve 1, cover plate 4, valve sleeve 7, first sealing ring 6 and second sealing ring 8 After assembly, it is inserted into the insertion hole 51 of the cartridge valve block 5, and during this process, the first sealing ring 6 and the second sealing ring 8 are deformed by extrusion. Then, insert the hexagon socket head bolt 3 into the hole of the bolt 41 of the cover plate 4 and tighten it. Finally, screw in the stop screw 2 so that the end surface of its tail sinks into the surface of the cover plate 4 by about 1 mm.

The disassembly process is as follows: First, unscrew the two hexagon socket head cap bolts 3 that do not have stop screws 2 on the top. Secondly, simultaneously or gradually loosen the two hexagon socket head bolts 3 with stop screws 2 on the top, since the stop screws 5 limit the relative movement between the hexagon socket bolts 3 and the cover plate 4, the cartridge valve assembly Will rise simultaneously to realize the dismounting process of valve sleeve 7 and cartridge valve block 5.

The above-mentioned embodiments are only described to the preferred implementation of the utility model, and are not limited to the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the utility model.

The parts not involved in the utility model are all the same as the prior art or can be realized by adopting the prior art.
