Specifically, the guide sleeve 5 of the needle valve 6 is installed in the valve port 7 in an interference fit manner; when the guide sleeve 5 is in operation, the head end of the pull rod 1 is inserted into the inner hole of the guide sleeve 5 from the valve port 7 of the needle valve 6 and extends out, so that the limiting part 8 arranged at the head end of the pull rod 1 is positioned at the outer side of the inner end of the guide sleeve 5, and the limiting part 8 is abutted against the end part of the inner end of the guide sleeve 5 when the pull rod 1 is pulled outwards by adjusting the axial position of the pull rod 1, so that the guide sleeve 5 can be pulled outwards along the axial line of the valve port 7 under the action of the external force provided by the driving part, and the guide sleeve 5 is detached from the valve port 7.
It should be noted that the size of the limiting portion 8 may be limited, so that the limiting portion 8 may move along the axis of the inner hole of the guide sleeve 5 along with the head end of the pull rod 1, thereby facilitating the assembly and disassembly of the pull rod 1 in the guide sleeve 5.
When the needle valve guide sleeve taking-out device provided by the utility model is applied, the head end of the pull rod 1 is inserted into the inner hole of the guide sleeve 5 until the limiting block arranged at the head end of the pull rod 1 is positioned at the outer side of the inner end of the guide sleeve 5, and the position of the pull rod 1 is adjusted along the radial direction and the axial direction of the valve port 7 so that the limiting block is contacted with the end part of the inner end of the guide sleeve 5, and a subsequent worker can drive the pull rod 1 to move axially outwards through the power part so as to drive the guide sleeve 5 to be separated from the valve port 7, thereby completing the disassembly of the guide sleeve 5.
The whole disassembly process is short in time consumption and high in convenience, the needle valve 6 does not need to be cooled, the disassembly efficiency can be improved, the needle valve 6 can be quickly maintained, and the influence of maintenance on the production period is reduced.
On the basis of the above embodiment, the power section includes: the bearing mechanism is connected to the tail end of the pull rod 1; an impact mechanism that is movable outward in the axial direction of the tie rod 1 to impact the carrier.
During operation, after the position of the pull rod 1 is radially adjusted at the valve port 7 so that the limiting part 8 contacts with the end part of the inner end of the guide sleeve 5, a worker drives the impact mechanism to move towards the tail end of the pull rod 1 along the axial direction of the pull rod 1 so as to impact the bearing mechanism arranged at the tail end of the pull rod 1 and positioned outside the valve port 7, thereby driving the guide sleeve 5 to move outwards in the axial direction, and finally detaching the guide sleeve 5 can be realized.
On the basis of the embodiment, the striking mechanism comprises an impact block 3 which is sleeved at the tail end of the pull rod 1 in a sliding way, and the impact block 3 is provided with a plurality of handles;
specifically, the impact block 3 is provided with a sliding hole for sliding insertion of the pull rod 1, and the assembly process is as follows: sleeving the impact block 3 at the tail end of the pull rod 1 in advance, and then fixing the bearing part on the pull rod 1 to finish the installation of the impact block 3; when the device is implemented, handles can be respectively arranged at the two ends of the impact block 3, so that a worker can hold the handles to drive the impact block 3 to move along the axial direction of the pull rod 1; repeatedly impacting the force bearing mechanism through the impact block 3, and taking out (ejecting) the guide sleeve 5 by utilizing inertia force; preferably, an insulating sleeve may be provided on the handle to insulate heat transfer.
On the basis of the embodiment, the force bearing mechanism comprises a limit nut 4 which is connected with the pull rod 1 in a threaded manner;
specifically, the force bearing mechanism is set as the limit nut 4, so that the limit nut 4 and the pull rod 1 are detachably connected, and the impact block 3 is convenient to disassemble, assemble and maintain (or replace).
In order to achieve a better technical effect, on the basis of the embodiment, the device also comprises a positioning sleeve 2 sleeved on the pull rod 1; the diameter of the inner hole of the positioning sleeve 2 is larger than the outer diameter of the pull rod 1, so that the pull rod 1 can move along the radial direction of the positioning sleeve 2 to adjust the position of the limiting block; and when in operation, the positioning sleeve 2 is inserted into the valve port 7 of the needle valve 6 and is in clearance fit with the valve port 7.
The positioning sleeve 2 is positioned in the valve port 7 and is used for positioning the pull rod 1 (namely, the axial position of the pull rod 1 relative to the valve port 7 is equivalent to the action of a bushing); the positioning sleeve 2 is arranged, so that the guide sleeve 5 is balanced and stable in stress in the impact process, namely under the action of impact force; if the gap between the pull rod 1 and the valve port 7 is too large, the flow guiding sleeve 5 is stressed and is poor in stability in the taking-out process after external force is applied, and the taking-out process is easy to be strained.
