Abstract
A kind of pipeline locking apparatus, is characterized in that: described pipeline locking apparatus, is tubular lock ring in the middle of agent structure, and two ends are all with the locking plate of energy bending, and often end has 2 ~ 8 locking plates; The overall width L2 of described lock ring is not more than the minimum range L1 between pipe joint two twisting flanges.Aperture on lock ring is not less than the maximum outside diameter between pipe joint two twisting flanges.Advantage of the present utility model: pipeline locking apparatus described in the utility model, be used in the locking of pipeline connection, easy to assembly, not easily get loose, reliability is high.
Description
Technical field
The utility model relates to the locking device that removable pipeline connects, particularly a kind of pipeline locking apparatus.
Background technique
In removable mechanical connecting structure, often relate to the locking problem of phase accessory.Conventional minor diameter pipeline connecting mode mainly adopts internal and external threads to connect, connects mouth and sphere connect mouth or the conical surface and the conical surface and connect mouth and coordinate and realize sealing at the joint employing conical surface.In order to locking, the internal and external threads joint of two pipelines mainly adopts lock silk to lock, but adopts lock silk to lock, and have certain requirement to the technical merit of workman, and easily get loose after locking, locking effect is difficult to evaluation.
The number of turns of tightening when mutually tightening between two lock silks can not too much can not very little, too many lock silk intensity can be caused to decline, easy-rupturing during work; To loosen during work very little, affect locking effect.More than in engineering using process, these two kinds of problems all once occurred, therefore, adopted safety fuse cutout to lock, there is certain defect.In addition, carry out operating also relative complex in the process of locking at employing lock silk.
Model utility content
The purpose of this utility model is in order to easy to assembly, and not easily get loose, reliability is high, and spy provides a kind of pipeline locking apparatus.
The utility model provides a kind of pipeline locking apparatus, it is characterized in that: described pipeline locking apparatus, is tubular lock ring in the middle of agent structure, and two ends are all with the locking plate of energy bending, and often end has 2 ~ 8 locking plates.
The overall width L2 of described lock ring is not more than the minimum range L1 between pipe joint two twisting flanges.
Before lock ring does not carry out locking bending, two ends are respectively with the locking plate of 4 energy bendings.
Aperture on lock ring, the φ B namely in Fig. 2, is not less than the maximum outside diameter between pipe joint two twisting flanges, the φ A namely in Fig. 1.
When assembling, first lock ring is inserted in the two part neutral positions that pipeline connects, L1 place; Then pipeline is tightened, after pipeline is tightened, tear the locking plate on lock ring both sides open curved being pressed in outside the twisting of pipe joint laterally, thus realize the locking that pipeline connects mouth, shown in Fig. 3.
Advantage of the present utility model:
Pipeline locking apparatus described in the utility model, be used in the locking of pipeline connection, easy to assembly, not easily get loose, reliability is high.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is conventional pipeline locking mode schematic diagram;
Fig. 2 is the utility model pipeline locking apparatus schematic diagram;
Fig. 3 is the assembling schematic diagram after adopting pipeline locking apparatus;
In figure, 1 is the first connecting pipeline, and 2 is the second connecting pipeline, and 3 is lock silk, and 4 is twisting flange, and 5 is twisting flange, and 6 is lock ring both sides, and 7 is locking plate.
