Description
Technical field
The utility model belongs to the dredger field, especially a kind of connection sealing configuration of dredging sludge drainage pipe.
Background technique
Dredging works mainly refers to the method with waterpower or machinery, excavate the cubic metre of earth and stone under water and carry out the process of transport process, be mainly used in rivers and lakes dredging, widen and dig dark, all significant for harbour and urban construction and even development economic and society.In dredging operation, dredger and sludge drainage pipe are all the equipment of generally applying, and wherein sludge drainage pipe mainly is divided into plain carbon steel sludge drainage pipe and composite dredge pipe.
The plain carbon steel sludge drainage pipe is mainly formed by steel pipe and flange welding, simple in structure, cost of production is low, usually adopt following preparation process: steel tube head is lower than flange operative end surface 1-2mm, after the weld seam welding is completed, its weld bead height should not exceed the flange operative end surface, higher than manual the polishing of weld seam employing of flange.There is following drawback in the steel sludge drainage pipe that this preparation process forms: one is after two sludge drainage pipes dock, the inside of flange connections can produce obvious gap each other, dredging soil can produce eddy current at gap location while flowing through, easily end face of flange is worn out and destruction flange sealing rubber pad sheet; The 2nd, end face of flange can produce larger distortion with welding, has reduced the sealability of end face of flange.
In the composite dredge pipe product, the composite dredge pipe that notice of authorization number provides a kind of dredger to use for the patent of CN201731185U, comprise plain carbon steel outer tube, rich chromium cast iron inner tube and packed layer, the rich chromium cast iron inner tube is integrated manufacturing, without the inwall seam, this model utility has advantages of long service life, good airproof performance, but this model utility weight is large, installation is inconvenient, and making is complicated, cost of production is high.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of connection sealing configuration of dredging sludge drainage pipe, has long service life, good airproof performance, the characteristics that easy for installation and cost of production is low, has facilitated the carrying out of dredging operation.
the technical solution of the utility model is: a kind of connection sealing configuration of dredging sludge drainage pipe, comprise left bank mud pipe unit, right sludge drainage pipe unit and gasket seal, it is characterized in that: described left bank mud pipe unit and right sludge drainage pipe unit arrange in opposite directions, gasket seal is clipped between left bank mud pipe unit and right sludge drainage pipe unit, left bank mud pipe unit, be bolted between gasket seal and right sludge drainage pipe unit, left bank mud pipe unit comprises steel pipe, flange, annular guard board and gusset, described steel tube end part is welded with annular guard board, gusset and flange, right sludge drainage pipe unit is identical with left bank mud pipe unit structure.
Described flange is provided with 16-32 screw, and is evenly distributed on end face of flange.
Described gusset is arranged at equably between steel pipe and flange, and the number of gusset is the 8-16 piece.
Described gusset is provided with two and crosses welding hole.
Described gasket seal be provided with flange on the perforate that is used in combination of screw.
The beneficial effects of the utility model are:
1. the utility model belongs to the linkage structure between the plain carbon steel sludge drainage pipe, adopted new processing technique, can make before processing steel tube end part higher than or fair with end face of flange, flange is enclosed within the steel pipe external welding, convenient welding, annular guard board and gusset also are welded on steel tube end part, thereby have strengthened integrally-built intensity, have extended working life;
2. the utility model is processed end face of flange by lathe after above-mentioned weld job is completed, thereby welding deformation and the flatness that guarantees end face of flange with respect to prior art eliminability orchid, eliminated the gap between flange, improve significantly the vortex phenomenon between flange, improved the sealability of structure;
3. the utility model is simple in structure, and is lightweight, easy for installation, and based on new processing technique, is made, and can carry out producing clean and efficiently, thereby significantly save cost of production.
Description of drawings
Fig. 1 is the sectional drawing of the connection sealing configuration of dredging sludge drainage pipe described in the utility model;
Fig. 2 is the enlarged view of A part in Fig. 1.
In figure, the 1-steel pipe, the 2-flange, the 3-gusset, the 4-screw, the 5-weld seam, the 6-annular guard board, the 7-gasket seal, 31-crosses welding hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
as depicted in figs. 1 and 2, a kind of connection sealing configuration of dredging sludge drainage pipe, comprise left bank mud pipe unit, right sludge drainage pipe unit and gasket seal 7, left bank mud pipe unit is identical with right sludge drainage pipe modular construction but arrange in opposite directions, left bank mud pipe unit comprises steel pipe 1, flange 2, annular guard board 6 and gusset 3, steel pipe 1 end is welded with annular guard board 6, gusset 3 and flange 2, form weld seam 5 between weld such as flange 2 and steel pipe 1, be provided with equably 24 screws 4 on flange 2 end faces, gusset 3 has 12, be welded on equably between steel pipe 1 and flange 2, and because annular guard board 6 welds and form another two weld seam (not shown) with steel pipe 1 and flange 2 respectively, every block of gusset 3 is provided with two mistake welding holes 31 and holds this two weld seam (not shown), gasket seal 7 is clipped between left bank mud pipe unit and right sludge drainage pipe unit, gasket seal 7 be provided with flange 2 on 24 perforates being used in combination of screw 4, thereby form left bank mud pipe unit, can be by the effect of bolton and sealing between gasket seal 7 and right sludge drainage pipe unit.
