Abstract
The utility model relates to the technical field of high-pressure manifold connection and provides a high-pressure expansion joint for a steel structure. The high-pressure expansion joint comprises a hollow shaft body, a lock ring, a circlip, a lock plate, a female joint and a bolt sleeve, wherein a boss is arranged at the lower part of the female joint, the right end of the hollow shaft body is fixed in the lock ring via the lock plate and the circlip, the left part of the hollow shaft is sheathed in the right part of the female joint, an outer boss is arranged at the middle part of the hollow shaft body, an inner boss is arranged at the right end of the bolt sleeve, the bolt sleeve is fixedly installed on the female joint via threads, the right side face of the outer boss is abutted against the left side face of the inner boss, and a sealing device is installed between the left end of the hollow shaft body and the inner wall of the right cavity of the female joint. The high-pressure expansion joint has reasonable structure and convenience for use, the hollow shaft can move from left to right by rotating the bolt sleeve, so that the pipeline length of the middle connecting segment can be adjusted, the working efficiency is greatly increased, and potential safety hazards are reduced.
Description
Technical field
The utility model relates to high pressure pipe joint interconnection technique field, is the expansion joint of a kind of steel structure high pressure.
Background technique
In the high pressure pipe joint connection procedure, since the difficulty accurate in place of machining accuracy or place restriction or main equipment, the inappropriate situation of linkage section length of pipeline in the middle of often occurring.All be that field by using is joined the intermediate section length of pipeline at every turn surely or cooperated by large-scale lifting appliance and installs after debugging reaches installation conditions repeatedly generally speaking, exist like this intensity low, complicated, inefficiency is installed and is had the problem of potential safety hazard.
Summary of the invention
The utility model provides the expansion joint of a kind of steel structure high pressure, has overcome the deficiency of above-mentioned existing technology, and it can effectively solve and have the problem that intensity is low, complicacy, inefficiency are installed and are had potential safety hazard when high pressure pipe joint connects.
The technological scheme of the utility model realizes like this: the expansion joint of a kind of steel structure high pressure comprises hollow axis body, retainer, circlip, locking plate, female joint and bolt sleeve; The left part of female joint inner chamber has boss; The right-hand member of hollow axis body is fixed in the retainer through locking plate and circlip, and the left part of hollow axis body is sleeved in the right part of female joint, at the middle part of hollow axis body outer lug boss is arranged; The right-hand member of bolt sleeve has inner convex platform; Bolt sleeve is fixedly mounted in the female joint through screw thread, and the right flank of outer lug boss withstands on the left surface of inner convex platform, between the inwall of hollow axis body left end and female joint right part cavity, seal arrangement is installed.
Comprise seal ring and seal ring with upper sealing device, between the inwall of hollow axis body left end and female joint right part cavity, seal ring, seal ring are installed in regular turn.
Above bolt sleeve can be fixedly mounted in the female joint and the ability move left and right through trapezoidal thread.
Can be distributed with at least two removal holes on the right-hand member of above bolt sleeve.
The utility model is rational in infrastructure, and is easy to use, makes hollow shaft physical efficiency move left and right through the swivel bolt cover, thereby therefore linkage section length of pipeline in the middle of regulating has greatly improved working efficiency and reduced potential safety hazard.
Description of drawings
Fig. 1 looks the sectional structure schematic representation for the master of the utility model.
Coding among the figure is respectively: 1 is hollow axis body, and 2 is retainer, and 3 is circlip, and 4 is locking plate, and 5 are female joint, and 6 is bolt sleeve, and 7 is boss, and 8 is outer lug boss, and 9 is inner convex platform, and 10 is seal ring, and 11 is seal ring, and 12 is removal hole.
Embodiment
As shown in Figure 1, the expansion joint of a kind of steel structure high pressure comprises hollow axis body 1, retainer 2, circlip 3, locking plate 4, female joint 5 and bolt sleeve 6; The left part of female joint inner chamber has boss 7; The right-hand member of hollow axis body 1 is fixed in the retainer 2 through locking plate 4 and circlip 3, and the left part of hollow axis body 1 is sleeved in the right part of female joint 5, at the middle part of hollow axis body 1 outer lug boss 8 is arranged; The right-hand member of bolt sleeve 6 has inner convex platform 9; Bolt sleeve 6 is fixedly mounted in the female joint 5 through screw thread, and the right flank of outer lug boss 8 withstands on the left surface of inner convex platform 9, between the inwall of hollow axis body 1 left end and female joint 5 right part cavitys, seal arrangement is installed.Like this; Guarantee high pressure sealing and necessary glade plane space through seal arrangement in use, during the linkage section length of pipeline, rotating bolt overlaps 6 in the middle of needs are regulated; Produce spacing between bolt sleeve 6 and the hollow axis body 1; Move right hollow axis body 1 this moment, and so just linkage section length of pipeline in the middle of the ability quick adjustment has improved working efficiency.
As shown in Figure 1, seal arrangement comprises seal ring 10 and seal ring 11, between the inwall of hollow axis body 1 left end and female joint 5 right part cavitys, seal ring 10, seal ring 11 is installed in regular turn.
As shown in Figure 1, for the ease of transmission, bolt sleeve 6 is fixedly mounted in the female joint 5 through trapezoidal thread and the ability move left and right.
As shown in Figure 1, for the ease of installation and removal, be distributed with at least two removal holes 12 on the right-hand member of bolt sleeve 6.
