Abstract
The utility model relates to easily-dismantle high-pressure studs and bolts, belonging to the technical field of coupling fastening pieces. The utility model is used for solving the problem that a high-pressure stud is difficult to dismantle and easy to damage. Heating holes are arranged along the axial lines of the stud and the bolt. The utility model is improved in that lubricant permeating holes are arranged on the stud and the bolt, and the lubricant permeating holes which are positioned in the screwing and combining positions of screw threads are communicated with the central heating holes 2. In the utility model, the lubricant permeating holes which are transversally communicated with the central heating holes are arranged on the high-pressure stud and bolt, which enables lubricant to swimmingly permeate to the positions among thread teeth, and the dismantlement of the stud is easier to carry out after the thread teeth are soaked by the lubricant for a short time, so the damage of the expensive high-pressure stud and bolt caused by dismantlement is avoided, and the maintenance cost of equipment is reduced in a vast scale. The utility model has the advantages of simple conformation and easy realization; the high-pressure stud and bolt which are used can be improved according to equipment conditions, and obvious effects can be received by a less investment, so the utility model has great practicability for being used for on-site equipment maintenance.
Description
Technical field
The utility model relates to a kind of connecting piece, is the high pressure double-screw bolt bolt that uses under the mesohigh condition specifically, belongs to connecting technical field of fastening.
Background technique
Spiral marking connection is being a kind of common bind mode, and, characteristics such as use flexible, convenient disassembly reliable with its connection are widely used.How parts such as the various bolts that use in the spiral marking connection, double-screw bolt, screw have realized standardization, select for use very convenient.In industries such as electric power, oil, chemical industry, the binding thread of some equipment is to work under condition of high voltage, bear the mesohigh load for a long time as power station turbine body double-screw bolt, bolt, this high pressure double-screw bolt, bolt are different with the installation requirement of plain bolt, normally first cold charge gives tightly fastening through heating again, so be provided with axial bottoming hole at double-screw bolt, bolt center, the usefulness of putting bolt electric heating rod during for heating.Equipment uses double-screw bolt after a period of time, bolt to cause the dismounting difficulty because of factors such as rust staining, foreign material alluvial and stress deformation, Installation Stress, even use loosening agent, oiling agent also of no avail, because loosening agent, oiling agent can't penetrate in the gap of internal and external threads, therefore in carrying out the overhaul of the equipments process, often dismantle difficulty and cause double-screw bolt, bolt failure, increase maintenance cost because of high-pressure bolt.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of quick detachable high pressure double-screw bolt, bolt that oiling agent infiltrates the hole that have is provided.
The alleged problem of the utility model is solved by following technological scheme:
A kind of quick detachable high pressure double-screw bolt, bolt are provided with the center bottoming hole along its axis, and its specialization is: described double-screw bolt, bolt are provided with oiling agent and infiltrate hole 3, and this hole is positioned at screw thread and screws the position, connect with center bottoming hole 2.
Above-mentioned quick detachable high pressure double-screw bolt, bolt, described oiling agent infiltrates 1～5 millimeter of bore dia, screws on the different heights position, position at the screw thread of described double-screw bolt, bolt and is provided with 1～10.
Above-mentioned quick detachable high pressure double-screw bolt, bolt, axis and the center bottoming hole axis angle α of institute that described oiling agent infiltrates the hole are 45 °～90 °.
The utility model improves at hot charging high pressure double-screw bolt Bolt dismantling difficulty, flimsy problem, oiling agent infiltration hole with its center bottoming hole lateral direction penetrating is set on high pressure double-screw bolt, bolt, oiling agent can be immersed between worm tooth smoothly, double-screw bolt, Bolt dismantling then more easily carry out after oiling agent soaks in short-term, thereby avoid expensive high pressure double-screw bolt to damage, reduce the device maintenance cost significantly because of dismounting.The utility model simple structure, be easy to realize that can improve employed high pressure double-screw bolt, bolt according to the equipment situation, very little input can be received obvious effects, be used for the field apparatus maintenance and have very much a practicability.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a high pressure bolt structure schematic representation;
Fig. 3 is the high-pressure bolt structural representation.
Each parts label is as follows among the figure: 1. high pressure double-screw bolt; 2. center bottoming hole; 3. oiling agent infiltrates the hole; 4. high-pressure bolt.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, high pressure double-screw bolt 1 described in the utility model or high-pressure bolt 4 are axially arranged with center bottoming hole 2 for satisfying the hot charging needs at it, after the improvement, have set up oiling agent and have infiltrated hole 3, and this hole is positioned at screw thread and screws the position, connect with center bottoming hole 2.According to the diameter difference of high pressure double-screw bolt, bolt, oiling agent infiltrates the diameter in hole and is advisable between 1～5 millimeter.Consider that reduce oiling agent infiltrates the hole to the influence of high pressure double-screw bolt, bolt strength and be beneficial to lubricatedly as far as possible, this Kongzui is arranged on well on the different heights position that screw thread screws the position, can take the circumstances into consideration to be provided with 1～10.Axis and the center bottoming hole axis angle α of institute that oiling agent infiltrates the hole are 45 °～90 °, consider easy to processly, and preferably α is 90 °.
The utility model is when dismounting, with plug the lower end of center bottoming hole is stopped up earlier, above the bottoming hole of center, inject oiling agent or loosening agent then, oiling agent or loosening agent infiltrate hole immersion screw thread through oiling agent and screw the position, after soaking a period of time, take out plug and emit loosening agent or oiling agent, again double-screw bolt, bolt are dismantled, just more or less freely.Facts have proved that high pressure double-screw bolt, bolt seldom are damaged, and both can reduce the device maintenance cost, can alleviate dismounting labor intensity again in unloading process after this improves.
