Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pressure, in particular to a one-way sinking valve sleeve disassembly tool. Background Art

[0002] The one-way sinking valve sleeve can only be installed from the single-side mounting hole end, and can only be removed from the single-side mounting hole end in the opposite direction when dismantled. It is often used in valve bodies with compact structure, reduced weight, and reduced external sealing structure. Since the valve sleeve can only enter and exit from the single-side hole, it cannot be dismantled like a conventional valve sleeve installed in a through hole, where an external thrust is applied to the valve sleeve from one side and it is pushed out from the other side. In the past, the dismantling of the one-way sinking valve sleeve mainly relied on the setting of dismantling structures such as threads on the valve sleeve, which was complex in design and large in size, often affecting the functional design of the valve sleeve. Utility Model Content

[0003] Purpose of the utility model: In view of the problems existing in the prior art, the purpose of the utility model is to provide a one-way installed submersible valve sleeve disassembly tool, which can realize the disassembly of the one-way submersible valve sleeve.

[0004] Technical Solution

[0005] A one-way installed submersible valve sleeve disassembly tool comprises a pull rod 1, a support rod 2, a nut 3, a transfer rod 4 and a pull rod 5. The pull rod 1 is arranged in the inner hole of the support rod 2, a groove is arranged at one end of the support rod 2, the tapered end of the pull rod 1 is close to the grooved end of the support rod 2, the maximum outer diameter of the tapered end of the pull rod 1 is the same as the outer diameter of the support rod 2, the threaded end of the pull rod 1 is connected to one end of the pull rod 5 through the transfer rod 4, and the nut 3 is screwed on the threaded end of the pull rod 1.

[0006] Furthermore, it also includes a sleeve 6, which is sleeved on the outside of the pull rod 5 and is clearance-matched with the pull rod 5.

[0007] Furthermore, a limiting boss is provided on the pull rod 5 to limit the movement of the pull rod 5 .

[0008] Furthermore, an auxiliary rod grip 7 is included, which is arranged at the other end of the pull rod 5 and is threadedly connected to the pull rod 5.

[0009] Furthermore, four evenly distributed grooves are provided at one end of the support rod 2 .

[0010] Furthermore, the inner hole clearance of the draw rod 1 and the support rod 2 is matched; one end of the transfer rod 4 is threadedly connected to the draw rod 1 , and the other end of the transfer rod 4 is threadedly connected to the pull rod 5 .

[0011] Technical effects:

[0012] The auxiliary rod is pulled by hand to drive the pull rod, and the pull rod pulls the extraction rod through the adapter rod. The tapered end of the extraction rod moves toward the direction of the support rod groove, gradually expanding the support rod groove. The support rod groove will fit tightly against the inner hole wall of the valve sleeve. Under the pulling force, the valve sleeve will move synchronously with the support rod, thereby realizing the disassembly of the one-way sinkable valve sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following embodiments are provided in conjunction with the accompanying drawings

[0019] For example, see the attached Figure 1-3 , a one-way sinking valve sleeve disassembly tool, including a draw rod 1, a support rod 2, a nut 3, a transfer rod 4, a pull rod 5, a sleeve 6, and an auxiliary rod grip 7;

[0020] The draw rod 1 is inserted into the inner hole of the support rod 2 and can move axially; and the tapered end of the draw rod 1 maintains the same direction as one end of the groove 8 of the support rod 2, so that when the draw rod 1 moves to the other end, the tapered end gradually opens the slice of the support rod 2, and drives the valve sleeve 9 to move by clamping the inner hole of the valve sleeve 9 through the slice; the other end of the draw rod 1 is connected to the transfer rod 4 and locked by the nut 3; the pull rod 5 is inserted into the sleeve 9, one end is connected to the external thread of the transfer rod 4, and the other end is connected to the auxiliary rod grip 7.

[0021] The utility model proposes a one-way installation submerged valve sleeve disassembly tool, which specifically includes a pull rod 1, a support rod 2, a nut 3, a transfer rod 4, and a pull rod 5. The pull rod 1 is arranged in the inner hole of the support rod 2, a groove is arranged at one end of the support rod 2, the tapered end of the pull rod 1 is close to the grooved end of the support rod 2, the maximum outer diameter of the tapered end of the pull rod 1 is the same as the outer diameter of the support rod 2, the threaded end of the pull rod 1 is connected to one end of the pull rod 5 through the transfer rod 4, and the nut 3 is screwed on the threaded end of the pull rod 1 to lock the pull rod to prevent the pull rod and the connecting rod from loosening.

[0022] Furthermore, it also includes a sleeve 6, which is sleeved on the outside of the pull rod 5 and is clearance-matched with the pull rod 5.

[0023] Furthermore, a limiting boss is provided on the pull rod 5 to limit the movement of the pull rod 5 .

[0024] Furthermore, an auxiliary rod grip 7 is included, which is arranged at the other end of the pull rod 5 and is threadedly connected to the pull rod 5.
