Background
The reversing valve has two pressure inlets and one pressure outlet. When one of the pressure inlets is provided with pressure, namely hydraulic pressure or air pressure is introduced, the inner shuttle peg moves to the other cavity inlet under the action of the pressure, and the valve is matched and sealed with the base under the action of the spring force, so that the pressure is ensured not to leak. After the product works for a long time, because solid impurities generated by abrasion of hydraulic accessories exist in hydraulic oil, surface damage often exists on sealing surfaces of the valve and the base, and the tightness of the product is reduced. The fit clearance between the base and the reversing valve shell is only 16-68 mu m, and the reversing valve is installed in the shell through a rubber ring on the base, so that the reversing valve is difficult to decompose. If the base is not disassembled, the sealing surface of the base cannot be repaired, and the sealing failure between the valve and the base is possibly caused, so that the functions of the hydraulic system are affected. In the repairing process of the reversing valve, the base needs to be disassembled, and if the sealing surface of the base is damaged, the base needs to be repaired.

Detailed Description
The present utility model will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand.
As shown in fig. 1 to 5, a reversing valve base disassembly tool comprises a shell 1 slowly extending into a reversing valve shell and a mandrel 3 in running fit with the shell 1, wherein the shell 1 is provided with a nut 2 which is propped against the reversing valve shell through an end face and gradually rotates to drive the mandrel 3 and a base to withdraw from the reversing valve shell, and a cushion block 4 is arranged between the nut 2 and the reversing valve shell.
As shown in fig. 2, the shell 1 screwed with the nut 2 slowly stretches into the reversing valve shell during disassembly, the expansion sleeve at the bottom end of the shell 1 enters the reversing valve base hole, and the mandrel 3 is screwed into the shell 1 until stopping.
The spacer 4 reduces the number of rotations of the nut 2 when disassembled to a large diameter.
As shown in fig. 2, the outer diameter thread of the casing 1 is matched with the nut 2, the expansion sleeve at the bottom end of the casing 1 is tightly attached to the reversing valve base, the nut 2 is attached to the reversing valve casing by screwing the nut 2 from the top end to the bottom end of the casing 1, and the reversing valve base is screwed out along with the casing 1.
The inner diameter thread of the shell 1 is matched with the mandrel 3.
Reference numeral a in fig. 1 denotes a reversing valve housing, and reference numeral b denotes a base.
Reference character c in fig. 4 denotes a top end of the housing, and reference character d denotes a bottom end of the housing.
The top of the shell 1 is provided with knurls which prevent the shell 1 and the mandrel 3 from sliding when being screwed, so that the tool is conveniently driven to separate the base from the reversing valve shell.
The bottom of the shell 1 is provided with a four-flap type expansion sleeve, and the mandrel 3 is driven to advance and retreat through the rotation of the tail end thread structure, so that the expansion sleeve is conveniently fixed in the base.
The mandrel 3 is used for expanding the expansion sleeve at the bottom of the shell 1, and when the mandrel is at a large diameter, a cushion block 4 is additionally arranged between the nut 2 and the reversing valve shell, and the nut 2 is continuously rotated until the reversing valve base is completely screwed out.
The specific process steps are as follows:
1. fixing the expansion sleeve: the shell 1 with the nut 2 is penetrated into a central hole of a base in the reversing valve, and the mandrel 3 is screwed into the shell 1, so that an expansion sleeve at the bottom end of the shell 1 and the base of the reversing valve are fixed;
2. primary unscrewing: by screwing the nut 2 from the top end to the bottom end of the housing 1, the base of the reversing valve slowly unscrews from the first position of engagement following the housing 1 until the base moves to the large diameter inside the reversing valve housing;
3. cushion blocks are used: placing a cushion block 4 between the housing 1 and the nut 2;
