Description
Technical field
The utility model relates to a kind of fastening means of pipeline, especially relates to a kind of revolving Petrochemical Pipe Joints.
Background technique
At present, the Placement of various pipeline has following several: rely on flange plate to weld between metallic pipe coupling, mechanical strength is high, but requires high to welding technique, and the amount of labour is large; Sweat soldering between plastic pipe, welding quality is more stable, and work efficiency is also high, but bearing capacity is low, is only applicable to the connection between hot-melt plastic material; Bonding docking between fiber reinforced plastic pipe, easy to operate, but work efficiency is low, and bearing capacity is poor; Also have the most general being threaded by pipe joint, there is detachability, easy for installation, but double thread processing request is high.The KC joint of particularly present integral type, easily by the distortion of whole KC joint when threaded pipe one end rotates.
Model utility content
The utility model is the deficiency being subject to rotating force torsional deformation in order to overcome existing screw-shaped pipe coupling, provides a kind of revolving Petrochemical Pipe Joints of anti-twisting.
To achieve these goals, the utility model is by the following technical solutions:
The revolving Petrochemical Pipe Joints of one of the present utility model, comprise connecting head main body and rotary sleeve, described connecting head body interior hollow, connecting head body exterior one end is provided with concave-convex grain, the other end of connecting head body exterior is socketed described rotary sleeve, described rotary sleeve is provided with nut and screw thread, and rotary sleeve one end is connected in the L shape groove that connecting head body outer wall is provided with, the rotary sleeve the other end by arrange back-up ring formed rotary sleeve connecting head body shaft to fixed structure.
Petrochemical Pipe Joints of the present utility model is not traditional integral type, point in order to connecting head main body and rotary sleeve two-part.Screw thread on rotary sleeve is for connecting other pipelines and mechanical whorl parts.Nut convenient wrench on rotary sleeve rotates, and in rotary sleeve screwing operations, connecting head main body does not follow rotation, effectively prevent connecting head main body and distorts by rotating force effect.
The rotary pipeline connecting head of separation structure, convenient disassembly.Rotary sleeve is axially connected in connecting head main body by back-up ring and L shape groove, rotary sleeve is entered altogether with connecting head main body in the axial direction and moves back altogether, but be separated from each other in rotary motion.
Connecting head body exterior one end is provided with concave-convex grain, when being socketed flexible pipe, and not easily slippage.
As preferably, be provided with seal ring between connecting head main body and rotary sleeve, described seal ring is arranged in the Baltimore groove of connecting head body outer wall.Rotary sleeve and connecting head main body are separation structures when rotating, and connect seal ring prevent from revealing when connecting fluid line.
As preferably, described seal ring is provided with three side by side.Reinforcement sealing structure, three is the better selection considering cost of material and the tight situation of sealing side by side.
As preferably, described connecting head main body the other end outer wall is provided with back-up ring draw-in groove, and rotary sleeve the other end end edge is provided with arc groove, and described back-up ring is arranged between back-up ring draw-in groove and arc groove.Back-up ring generally adopts spring steel, embeds between back-up ring draw-in groove and arc groove, is connected firmly.
As preferably, after the outer wall arc convex of connecting head body midsection position concave-convex grain end, indentation forms described L shape groove.Outer wall arc convex is the thickness in order to strengthen outer wall, and L shape groove is as the restraining groove of rotary sleeve one end, and the outer wall of connecting head main body needs certain thickness could form the depth of rebate of L shape groove.
As preferably, described concave-convex grain is the stepped shape groove that the brim of a hat shape forms connecting head body outer wall.Flexible pipe easily packs into not easily slippage out.
The utility model has following beneficial effect: when rotation mode connects other pipelines, easy for installation, connecting head is distortion not easily; Connecting head good airproof performance, the not easily slippage of socket flexible pipe.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
In figure: connecting head main body 1, rotary sleeve 2, seal ring 3, back-up ring 4, concave-convex grain 5, nut 6, screw thread 7, L shape groove 8, arc convex 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1 and Figure 2, a kind of revolving Petrochemical Pipe Joints, comprises connecting head main body 1 and rotary sleeve 2.Connecting head main body and rotary sleeve are all hollow circular-tube structures.Connecting head body interior hollow, connecting head body exterior one end is provided with concave-convex grain 5, the other end socket rotary sleeve of connecting head body exterior.
For convenience of connecting head socket flexible pipe, concave-convex grain 5 forms the stepped shape groove of connecting head body outer wall in the brim of a hat shape, prevent the flexible pipe slippage be socketed.
Rotary sleeve is provided with nut 6 and screw thread 7.Nut is hexagon nut, and convenient wrench rotates; Screw thread 7 is outside thread, for connecting other pipelines.
The outer wall arc convex 9 of connecting head body midsection position concave-convex grain end is to increase thickness, and then indentation forms L shape groove 8, and rotary sleeve one end is connected in this L shape groove 8, as the limit structure of rotary sleeve one end.The rotary sleeve the other end by arrange back-up ring 4 formed rotary sleeve connecting head body shaft to fixed structure.Connecting head main body the other end outer wall is provided with back-up ring draw-in groove, and rotary sleeve the other end end edge is provided with arc groove, and back-up ring is arranged between back-up ring draw-in groove and arc groove.Rotary sleeve enters altogether with connecting head main body in the axial direction and moves back altogether, but is separated from each other in rotary motion, and when preventing rotary sleeve to be rotatably connected, rotating force makes connecting head main body torsional deformation.
Owing to being separation structure when rotary sleeve and connecting head main body rotate, when connecting fluid line, for preventing revealing, be provided with seal ring 3 between connecting head main body and rotary sleeve, seal ring is arranged in the Baltimore groove of connecting head body outer wall.Seal ring 3 is provided with three side by side.
This revolving Petrochemical Pipe Joints, when rotation mode connects other pipelines, easy for installation, connecting head is distortion not easily; Connecting head good airproof performance, the not easily slippage of socket flexible pipe.
