Abstract
The utility model discloses a sealing joint disassembling device for a glass steel tube, which comprises a drive sleeve, a thrust bearing and a fixed sleeve, wherein the inside of the drive sleeve is provided with internal threads which are matched with external threads of an adapter and the drive sleeve is rotationally arranged on the fixed sleeve through the thrust bearing. The sealing joint disassembling device for the glass steel tube is convenient to operate, is time-saving and high-efficiency, can protect a seal ring and the end face of the glass steel tube under the condition of disassembling the joint, reduces the working strength and improves the work efficiency of disassembly.
Description
Technical field
The utility model belongs to the oil well test field, relates in particular to a kind of device that is used to dismantle induction logging instrument glass reinforced plastic pipe and joint.
Background technology
Induction logging instrument glass reinforced plastic pipe and joint adopt O shape ring hermetically-sealed construction, and glass reinforced plastic pipe is not threaded with joint, the dismounting difficulty.The main employing earlier of dismounting at present prized a small gap with a word screwdriver at glass reinforced plastic pipe and connector engages end face, is pulled outwardly with swivel joint limit on hand again, and labour intensity is big, inconvenient operation, and not only efficient is low, and damages sealing ring and glass reinforced plastic pipe end face easily.
The utility model content
The technical problems to be solved in the utility model provides the provision for disengagement of a kind of glass reinforced plastic pipe seal nipple, and this device disassembles glass reinforced plastic pipe and seal nipple easily.
In order to address the above problem, the utility model provides the provision for disengagement of a kind of glass reinforced plastic pipe seal nipple to comprise: active cover, thrust bearing and fixed cover, initiatively be provided with the internal thread that matches with the adapter external screw thread in the cover, this initiatively overlaps by thrust bearing is rotatable and is installed on the fixed cover.
Preferably, described fixed cover comprises two semi-rings, and these two semi-rings are fastened togather by screw.
The utlity model has following advantage:
1) fixed cover of employing open-close type fastening structure is convenient to the installation of extracting tool, the location and the clamping force adjustment of thrust bearing;
2) utilize the screw thread of joint itself to come transmission, the mutarotation transhipment is moving for rectilinear motion, and is simple in structure, easy to operate;
3) have at the same time between two parts that relatively rotate and relatively move and adopt thrust bearing, effectively transmit pulling force, reduce friction simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to schematic cross-section;
Structural representation when Fig. 3 uses for the utility model.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model comprises: initiatively overlap 1, thrust bearing 3 and fixed cover 2, initiatively overlap and be provided with the internal thread that matches with adapter 6 external screw threads in 1, this initiatively overlaps 1 by thrust bearing 3 rotatable being installed on the fixed cover 2.Fixed cover 2 comprises two semi-rings, and these two semi-rings are fastened togather by screw 4.
When the utility model uses, as shown in Figure 3, earlier thrust bearing 3 is enclosed within on the glass fibre reinforced plastics casing 5; Two semi-rings of fixed cover 2 are fixed on the glass fibre reinforced plastics casing 5 by screw 4, simultaneously thrust bearing 3 are buckled in two semi-rings; Initiatively overlap 1 with adapter 6 screw thread transmissions, turn initiatively overlaps 1, adapter 6 is moved to the left, fixed cover 2, initiatively overlaps 1 counter-force is passed to adapter 6, thereby adapter 6 is withdrawed from from glass fibre reinforced plastics casing 5 endoporus to initiatively overlapping 1 axial counter-force by thrust bearing 3.
Sealing ring and glass fibre reinforced plastics casing 5 end faces can be protected in easy to operate, the time-saving and efficiency of the utility model when dismounting adapter 6, reduced working strength, have improved dismantlement work efficient.
The above only is a preferable possible embodiments of the present utility model; be not so promptly limit protection domain of the present utility model; so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes and changes in material, all in like manner all is included in the scope of the present utility model.
Claims (2)
1, a kind of glass reinforced plastic pipe seal nipple provision for disengagement is characterized in that, comprising: active cover, thrust bearing and fixed cover, initiatively be provided with the internal thread that matches with the adapter external screw thread in the cover, and this initiatively overlaps by thrust bearing is rotatable and is installed on the fixed cover.
2, a kind of provision for disengagement as claimed in claim 1 is characterized in that, described fixed cover comprises two semi-rings, and these two semi-rings are fastened togather by screw.
