Above-mentioned good sealing effect, prefabricated direct-buried thermal insulation pipe easy to connect, described clip is two semicircle snap rings, on the inwall of semicircle snap ring, there is twice semi-circular projection, the degree of depth of the height of projection and the groove at thermal insulation pipe two ends matches, the distance of the groove between the thermal insulation pipe of the connection relative to two of the distance between twice projection matches, there is respectively connecting screw hole at the two ends of two snap rings, and connecting bolt closely connects two snap rings through connecting screw hole.
Above-mentioned good sealing effect, prefabricated direct-buried thermal insulation pipe easy to connect, between described clip inwall and the outer wall at working steel tube two ends, there is seal washer, seal washer is ring, the outer ring surface of annulus, outer side surface, inner ring surface surround the hollow cavity of annulus, there is a circle gap at inner ring surface along circumference, gap is connected with hollow cavity, and the inner ring surface diameter of seal washer and the working steel tube external diameter of thermal insulation pipe match.
The beneficial effects of the utility model are:
The tubing Placement of prefabricated direct-buried thermal insulation pipe of the present utility model adopts clip groove Placement, there is groove at two ends at the working steel tube of thermal insulation pipe, the working steel tube of two thermal insulation pipes is connected fastening with clip, in construction, do not need welding, improve installation rate, thimble connector is lightweight, bolt quantity is few, easy for installation, in clip, have seal washer, unique gasket structure has ensured to connect the reliability of sealing.Very folk prescription is just in attended operation of the present utility model; without special professional skill, and good sealing effect, the quality problems such as seepage, fracture that conventional prefabricated direct-buried pipe causes because of welding procedure quality can effectively be solved; and can avoid the pollution of weld fume, be conducive to protect workman's health.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of thermal insulation pipe;
Fig. 3 is the structural representation of clip;
Fig. 4 is the front view of seal ring;
Fig. 5 is the A-A sectional view of Fig. 4.
In figure, mark is as follows: thermal insulation pipe 1, working steel tube 2, thermal insulation layer 3, outer pillar 4, groove 5, clip 6, projection 7, seal washer 8, connecting bolt 9, locking nut 10, outer ring surface 11, outer side surface 12, inner ring surface 13, gap 14, hollow cavity 15.
Embodiment
The utility model is made up of thermal insulation pipe 1, clip 6, seal washer 8, connecting bolt 9, locking nut 10.
In figure, show, thermal insulation pipe 1 body is working steel tube 2, and working steel tube 2 lays thermal insulation layer 3, has outer pillar 4 outside thermal insulation layer 3.Have respectively at the two ends of working steel tube 2 while connection around 5, two thermal insulation pipes 1 of groove of body circumference, the end face of the working steel tube 2 of two thermal insulation pipes 1 is relative, by clip 6, the groove 5 at two working steel tube 2 two ends is locked, and two thermal insulation pipes 1 are closely connected.In construction, do not need welding, improved installation rate, clip 6 joints are lightweight, bolt quantity is few, easy for installation.
In figure, show, clip 6 is two semicircle snap rings, on the inwall of semicircle snap ring, have twice semi-circular projection 7, the degree of depth of the height of projection 7 and the groove 5 of thermal insulation pipe 1 matches, and the distance of the groove 5 between the working steel tube 2 of the connection relative to two of the distance between twice projection 7 matches.When connection, twice projection 7 is embedded in twice groove 5, makes two working steel tubes 2 at axial restraint, can not move.There is respectively connecting screw hole at the two ends of two snap rings, and connecting bolt 9 is locked with locking nut 10 through connecting screw hole, and upper and lower two snap rings are connected and fixed, and two thermal insulation pipes 1 are closely connected.
In figure, show there is seal washer 8 between clip 6 inwalls and the outer wall at work 2 two ends.Seal washer 8 is ring, the outer ring surface 11 of annulus, outer side surface 12, inner ring surface 13 surround the hollow cavity 15 of annulus, there is a circle gap 14 at inner ring surface 13 along circumference, gap 14 is connected with hollow cavity 15, and inner ring surface 13 diameters of seal washer 8 and working steel tube 2 external diameters of thermal insulation pipe 1 match.Because seal washer 8 is resilient cushion rubbers, the internal diameter of seal washer 8 can be less than the external diameter of working steel tube 2 in the time of static state, is enclosed within on working steel tube 2 tightr when use.
Seal washer 8 is positioned at the jointing of the thermal insulation pipe 1 of two docking while installation, the gap 14 of inner ring surface 13 is relative with jointing.The outer surface that the inner ring surface 13 of seal washer 8 is enclosed within working steel tube 2 forms first sealing; When clip 6 is locked, seal washer 8 is subject to the pressure from clip 6 internal limitations, and passive being compressed on working steel tube 2 forms secondary seal; Fluid in thermal insulation pipe 1 enters the hollow cavity 15 of seal washer 8 from the gap 14 of the inner ring surface 13 of the seal washer 8 of jointing, liquid is from reacting on the inner side of seal washer 8 inner ring surfaces 13 in hollow cavity 15, thereby make inner ring surface 13 be pressed on the outer surface of working steel tube 2, reaching gapless closely cooperates, form three sealings, in pipeline, fluid pressure is larger, and sealability is better.
