Abstract
The utility model discloses an expansion joint component used for a pump. The expansion joint component comprises an expansion joint body (1), a seal pressure plate (2), a seal backing plate (3) and a fixed flange (7). The fixed flange (7) comprises a small fixed flange (8) and a movable flange (71). The small fixed flange (8) is welded to the end of the expansion joint body (1), and the movable flange (71) is movably installed on the expansion joint body (1) in a sleeved mode. The outer edge of the small fixed flange (8) does not extend to a flange hole of the movable flange (71). Under the condition that the shapes of part of existing components are changed very little, the expansion joint component is more convenient to connect with a pipeline better in a rotating mode in the installation process, and the expansion joint component is simple and convenient to use.
Description
Technical field
The utility model relates to a kind of pump, particularly relates to a kind of pump slip joint parts.
Background technique
Slip joint parts in conventional pump, first be that screw rod is worn to sealed bolster plate and sealing clamp, screw on after two nuts, casing coupling body flange and nut again stretch through, be connected with the pump bend pipe that spues again, then first the other end of slip joint and export pipeline are first connected and tightened, then adjust after the required extending amount of slip joint, tighten fixing.
In when assembling, the former slip joint parts flange that do not improve is fixedly to be welded on slip joint body, and the attachment hole on fastening flange bores, just suitable hole is fixing position, and the piping flange connecting is also fixed position substantially.So when connecting, often there will be, slip joint flange hole to not just, can not be gone up the situation appearance of bolt with the piping flange hole of docking.Solve on site is welded flange again just.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of when assembling slip joint parts, and slip joint flange hole aligns easy pump slip joint parts with the piping flange hole of docking.
In order to solve the problems of the technologies described above, the pump that the utility model provides slip joint parts, comprise slip joint body, sealing clamp, sealed bolster plate and fastening flange, described fastening flange comprises fixing little flange and loose flange, described fixing little flange welding is in the end of described slip joint body, described loose flange movable set is on described slip joint body, and the outer of described fixing little flange does not extend to the flange hole of described loose flange.
Adopt the pump slip joint parts of technique scheme, that screw rod is worn to sealed bolster plate and sealing clamp, screw on after two nuts, casing coupling body flange and nut again stretch through, be connected with the pump bend pipe that spues again, when then the other end of slip joint is connected with export pipeline, can adjust according to the hole on export pipeline flange the circumferential position of loose flange, spacer flanger neutral gear position can add suitable packing ring, and then with bolt, loose flange is pressed on fixing little flange and is connected with piping flange.
In sum, the utility model is in the shape situation of the existing part component of very little change, fastening flange on slip joint body, change fixing little flange and two flanges of loose flange into, when assembling slip joint parts, slip joint flange hole aligns easy pump slip joint parts with the piping flange hole of docking.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of pump of the present utility model.
Fig. 2 is the structural representation before the utility model improves.
Fig. 3 is the improved structural representation of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, slip joint parts in conventional pump, first be that screw rod 4 is worn to sealed bolster plate 3 and sealing clamp 2, between sealed bolster plate 3, sealing clamp 2 and slip joint body 1, O-ring seals 6 is installed, screws on after two nuts 5, then stretch through casing coupling body 1 flange and nut, be connected with the pump bend pipe that spues again, then first the other end of slip joint and export pipeline are first connected and tightened, then adjust after the required extending amount of slip joint, tighten fixing.
In when assembling, the former slip joint parts flange that do not improve is fixedly to be welded on slip joint body 1, and the attachment hole on fastening flange 7 bores, just suitable hole is fixing position, and the piping flange connecting is also fixed position substantially.So when connecting, often there will be, the flange hole of the fastening flange 7 on slip joint to not just, can not be gone up the situation appearance of bolt with the piping flange hole of docking.Solve on site just can only be welded and fixed flange 7 again.
Referring to Fig. 1 and Fig. 3, one end of slip joint body 1 is provided with sealed bolster plate 3 and sealing clamp 2, screw rod 4 is through sealed bolster plate 3 and sealing clamp 2 and be screwed with two nuts 5, between sealed bolster plate 3, sealing clamp 2 and slip joint body 1, O-ring seals 6 is installed, fastening flange 7 comprises fixing little flange 8 and loose flange 71, fixing little flange 8 is welded on another end of slip joint body 1, loose flange 71 movable sets are on slip joint body 1, and the outer of fixing little flange 8 does not extend to the flange hole of loose flange 71.
Referring to Fig. 1 and Fig. 3, first the fastening flange on slip joint body 17 is changed into fixing little flange 8 and loose flange 71, before the fixing little flange 8 of welding slip joint body 1, first by processing, put into slip joint body 1 with hole-drilled loose flange 71 and be welded and fixed again little flange 8.
When slip joint parts are installed, while being connected with pipeline flange, after only needing rotation loose flange 71 also to align completely with pipeline flange, can connect.
Claims (1)
1. pump slip joint parts, comprise slip joint body (1), sealing clamp (2), sealed bolster plate (3) and fastening flange (7), it is characterized in that: described fastening flange (7) comprises fixing little flange (8) and loose flange (71), described fixing little flange (8) is welded on the end of described slip joint body (1), described loose flange (71) movable set is upper at described slip joint body (1), and the outer of described fixing little flange (8) does not extend to the flange hole of described loose flange (71).
