Abstract
The utility model discloses a pipeline turning resistant device for an L-shaped rotary joint of a steam pipeline, which is a tube connector. A round hole and a hexagonal hole which are coaxial and communicated are respectively arranged at two ends of the connector, the round hole is matched with the pipeline, and the hexagonal hole is matched with a hexagonal boss of the L-shaped rotary joint. A groove for separating the connector is arranged on the end face of the round hole, and pressing blocks for contracting the round hole and clamping the pipeline are arranged on connectors on two sides of the groove. The L-shaped rotary joint and the pipeline are integrated through the connector, thereby fastening the pipeline, preventing the thread connection of L-shaped rotary joint and the pipeline from getting loose, avoiding steam leakage occurred on the thread connection portion and ensuring normal operation of equipment.
Description
(1) technical field:
The utility model relates to the tyre vulcanizer parts, is specially the L shaped swivel joint pipeline of a kind of steam pipework twist preventing apparatus.
(2) background technique:
The L shaped swivel joint of existing tyre vulcanizer steam pipework and pipeline connecting mode are for being threaded; When tyre vulcanizer folding mould, L shaped swivel joint is corresponding to rotate, because L shaped swivel joint sealing surface frictional force is bigger; The pipeline that is threaded with swivel joint is also rotated thereupon; Cause the pipeline of threaded connection place loosening, the steam in the pipeline is revealed from loosening screw thread, influences the normal use of tyre vulcanizer.
(3) model utility content:
The purpose of the utility model is the deficiency that overcomes the existing L shaped swivel joint of steam pipework, designs a kind of convenient and simple L shaped swivel joint pipeline twist preventing apparatus.
The L shaped swivel joint pipeline of the steam pipework twist preventing apparatus that can realize above-mentioned purpose is a connection piece; The two ends of different is said link are respectively coaxial circular hole that communicates and hex hole; Circular hole cooperates with pipeline; Hex hole cooperates with the hexagonal boss of L shaped swivel joint, and pipeline is threaded with L shaped swivel joint through circular hole; Set out one section separately groove of link in the circular hole end, be provided with on the link of these groove both sides circular hole is shunk the locking mechanism that clamps pipeline, through link L shaped swivel joint and pipeline are connected as a single entity, fastening pipeline prevents thread looseness.
Said groove is axial groove along axially offering of circular hole usually.
The groove face direction of said axial groove be circular hole radially.
Said axial groove is processed with milling mode, and for keeping circular hole end connection certain shrink amount, the milling length of axial groove is less than the circular hole degree of depth.
Said link adopts pipe fitting.
Said locking mechanism is the briquetting of being located on the pipe fitting of groove both sides, offers bolt perforating or bolt on each briquetting and is screwed into screw.
The advantage of the utility model:
The L shaped swivel joint pipeline of the utility model steam pipework twist preventing apparatus is a Pipe connecting fitting; The hex hole at its two ends and circular hole cooperate the hexagonal boss and clamping pipeline of L shaped swivel joint respectively; L shaped swivel joint and pipeline are connected as a single entity, and fastening pipeline prevents that L shaped swivel joint is loosening with being threaded of pipeline; Steam leakage takes place in threaded connection place never again, guarantees the normal operation of equipment.

(5) embodiment:
Fig. 1, Fig. 2, the L shaped swivel joint pipeline of the utility model steam pipework twist preventing apparatus shown in Figure 3; Be the tubular link 1 of L shaped swivel joint 3 with pipeline 2 (steel pipe) connection; Link 1 one ends are and the circular hole 4 (endoporus of tubular link 1 preferably is matched with pipeline 2 external diameters, and then circular hole need not be processed) of pipeline 2 Spielpassung that link 1 the other end processes the hex hole 5 that cooperates with the hexagonal boss of L shaped swivel joint 3 on the basis of endoporus; In link 1, mill out one section axial groove in circular hole 4 end faces; The groove face direction of this axial groove be circular hole 4 radially, the length of this axial groove is less than the degree of depth of circular hole 4, two briquettings 6 of welding on the link 1 of axial groove both sides; Offer the unthreaded hole or the screw of corresponding position on the briquetting 6, supply to wear bolt 7 usefulness or directly be screwed into bolt 7.
As shown in Figure 4; L shaped swivel joint 3, link 1 and pipeline 2 are combined together (pipeline 2 is threaded with L shaped swivel joint 3); Utilize bolt 7 locking briquettings 6 then; Thereby make the circular hole 4 locking pipelines 2 of link 1, the other end hex hole 5 cooperates chucking with the hexagonal boss of L shaped swivel joint 3.
