Abstract
The utility model provides a strain docking component, which comprises a upper steel tube, a lower docking tube, and a middle guide tube, wherein a flange plate of the lower end of the upper steel tube is connected with a flange plate of the upper end of the middle guide tube, and the lower end of the middle guide tube is plugged and connected with the upper port. The utility model of the strain docking component, compared with the existing technology, has the advantages of reasonable in design, simple in structure, simple in processing, convenient in installation and usage, safe, and durable, which has an excellent popularizing use-value.
Description
The utility model relates to a kind of mechanical fitting, and specifically a kind of strain of using on boiler chimney, engine exhaust pipe or air pipeline is to connected components.
The smoke-ejecting pipe of boiler chimney, big-block engine or air pipeline can be vibrated or heat is opened the influence of shrinkage and horizontal or vertical direction displacement or distortion are taken place in working procedure, and the result who is produced is that chimney or smoke-ejecting pipe break and damage and influence the normal operation of equipment in the course of time.The solution of prior art is to strengthen the rigidity of pipeline or adopt bellows to eliminate the influence that horizontal or vertical direction displacement or distortion are brought, and the in use existing deficiency of the method for above-mentioned solution is to have improved the cost cost and the installation and maintenance expense of equipment.
The purpose of this utility model provides a kind ofly eliminates strain that horizontal or vertical direction displacement or distortion impact equipment to connected components by dynamic connection.
The purpose of this utility model realizes in the following manner, guide pipe is connected in the middle of the pipeline in the middle of adopting, the horizontal dynamic seal ring is set on middle guide pipe eliminates the Horizontal displacement that overcomes pipeline with vertical dynamic seal (packing) ring, the location of eliminating the vertical contraction of pipeline also is set on middle guide pipe simultaneously eliminates the vertical effect of contraction that pipeline produces with Sealing, thereby, improve the operational reliability of equipment, reduced maintenance expenses.
Accompanying drawing is the structural representation of strain to connected components;
Explain below with reference to Figure of description strain of the present utility model being done connected components.
Strain of the present utility model is to connected components, its structure is to be made of last steel pipe 1, following butt tube 10, middle guide pipe 11, the flange plate 12 of last steel pipe 1 lower end joins with the flange plate 5 of middle guide pipe 11 upper ends, and the lower end of middle guide pipe 11 is plugged on the upper end-hole of butt tube 10.
The top of last steel pipe 1 lower end flange plate 12 is provided with horizontal dynamic seal ring 3 and vertical dynamic seal (packing) ring 2, the cylindrical of the cylindrical of horizontal dynamic seal ring 3 and middle guide pipe 11 upper flanges dishes 5 links together by seal ring 4, flange plate 12 cylindricals and the seal ring 4 of last steel pipe 1 lower end remain with the free gap, remain with the free gap between the interior circle of horizontal dynamic seal ring 3 and the cylindrical of last steel pipe 1, the interior circle of vertical dynamic seal (packing) ring 2 and the cylindrical of last steel pipe 1 slide and join.
The cylindrical of middle guide pipe 11 is provided with baffle ring 6, baffle ring 6 joins by the upper end of seal ring 7 with butt tube 10, vertically have guiding groove 9 on the tube wall of middle guide pipe 11, the tube wall of butt tube 10 is provided with locating stud 8, and the end of locating stud 8 is inserted in the guiding groove 9.
Embodiment:
Strain of the present utility model is very simple and convenient to its processing and fabricating of connected components, gets final product by general sheet metal rivet welding processes shown in the by specification accompanying drawing, installs and uses with other pipe connectors roughly the same.
Strain of the present utility model is compared with existing technology connected components, have reasonable in design, structure is simple Single, be easy to processing, the characteristics such as easy to install, safe and reliable and durable in use, thereby, have Good popularizing value.
