DETAILED DESCRIPTION

(10) Exemplary embodiments of the present disclosure will be described in more detail below in conjunction with the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to convey the complete scope of the present disclosure to those skilled in the art.

(11) Referring to FIG. 1 to FIG. 6, this embodiment provides a quick removal tooling for a valve core, which includes a clamping sleeve 1, a rotary cap 2, a nut 3, a capped screw rod 4, and a rotating handle 5.

(12) A first end portion of the clamping sleeve 1 is provided with a clamping protrusion 11 configured to be clamped with a valve body 10, and an avoidance groove 12 configured to avoid an outer end side of a valve core 20; and a second end portion of the clamping sleeve 1 is in sleeved connection with a first end portion of the rotary cap 2, so that the rotary cap 2 can rotate relative to the clamping sleeve 1. The nut 3 is fixed at a central hole 21 of the rotary cap 2. The rotary cap 2 is provided with a radial through hole 22 in a side wall close to a second end portion, and the radial through hole is perpendicular to the central hole 21 of the rotary cap. A through hole 51 is reserved in the middle of the rotating handle 5, and the rotating handle 5 is vertically inserted into the rotary cap 2 from the radial through hole 22, so that the through hole 51 of the rotating handle 5 is coaxial with the central hole 21 of the rotary cap 2 for the screw rod 4 to pass through. A screw portion of the capped screw rod 4 extends from the second end portion of the rotary cap 2, passes through the through hole 51 of the rotating handle 5, is matched with the nut 3 by threads, and then extends into the clamping sleeve 1 for achieving matched connection with internal threads of a central hole of the valve core 20.

(13) When in use, after the screw rod 4 is in screwed connection with the valve core 20, the rotating handle 5 is rotated to drive rotation of the rotary cap 2, and the rotary cap 2 drives rotation of the nut 3 so as to push the screw rod 4 to move linearly relative to the rotary cap 2, so that the valve core 20 is ultimately driven to be pulled out of the valve body 10. The removing process is shown in FIG. 7 and FIG. 8. FIG. 7 shows the state where the quick removal tooling for the valve core acts on the valve body, but the valve core is not pulled out; and FIG. 8 shows the state where the quick removal tooling for the valve core acts on the valve body, and part of the valve core is pulled out.

(14) Specifically, referring to FIG. 3 and FIG. 5, in this embodiment, a counter bored hole 23 is reserved in the second end portion of the rotary cap 2, and the nut 3 is clamped at the counter bored hole 23. That is, the rotating handle 5 is arranged at an upper end of the nut 3, which can prevent the nut 3 from getting away from the second end portion of the rotary cap 2.

(15) Preferably, referring to FIG. 3 and FIG. 6, in this embodiment, the quick removal tooling for the valve core further includes a clamp ring 6, a clamping slot 24 is formed in the first end portion of the rotary cap 2 that extends into the second end portion of the clamping sleeve 1, and the clamp ring 6 is arranged in the clamping slot 24 to prevent the rotary cap 2 from getting away from the clamping sleeve 1.

(16) Specifically, the clamp ring 6 is an E-shaped clamp ring.

(17) In this embodiment, the clamping sleeve 1 is provided with an observation window 13 in a side wall close to the second end portion, and the observation window is configured to observe whether the valve core 20 is pulled out in place. As shown in FIG. 8, when the end portion of the valve core 20 reaches the observation window 13, it indicates that the valve core 20 has been pulled out in place, and the removal tooling can be moved away from the valve body 10 to achieve the disassembly of the valve core 20.

(18) More preferably, as shown in FIG. 3 and FIG. 5, a bearing 7 is arranged at a part where the second end portion of the clamping sleeve 1 is in sleeved connection with the first end portion of the rotary cap 2. It is preferable to use a thrust bearing to better bear an axial force required by the removal tooling when the valve core is pulled out, thereby ensuring smooth disassembly of the valve core.

(19) In this embodiment, the clamping sleeve 1 and the rotary cap 2 are made of a lightweight metal material, such as an aluminum alloy material, which is light and easy to operate.

(20) The quick removal tooling for the valve core utilizes the lead screw principle and makes the valve core pulled out of the valve body easily through the cooperation of the screw rod and the nut, and the removing progress can be observed at any time during the disassembly process, so that the entire process is controllable, and the operation is easy and effortless. There is no need for other tools during the disassembly process, which is very efficient and labor-saving, and can also avoid damage to the valve body caused by improper disassembly.

(21) The foregoing descriptions are merely exemplary embodiments of the present disclosure, and are not intended to limit the present disclosure in any form. Some simple amendments, equivalent changes or modifications made by those skilled in the art based on the technical contents disclosed above shall fall within the protection scope of the present disclosure.
