Abstract
The utility model relates to a high-speed movable joint for reducing pipelines, which is composed of a reducing bushing 1, sealing rings 2 and 3, press covers 4 and 5, and screw-bolts 6. The reducing bushing 1 is sheathed on circular pipelines 7 and 8. The sealing rings 2 and 3 are respectively sheathed on the pipelines 7 and 8. The inner end faces of the sealing rings 2 and 3 are respectively and tightly bonded with the two end faces of the reducing bushing 1. The outer diameter and the outer end face of the sealing rings 2 and 3 are respectively and tightly bonded with the press covers 4 and 5 which are fastened by a plurality of screw-bolts 6. The utility model solves the problem of the quick connection of the reducing pipelines.
Description
The utility model belongs to a kind of pipe joint, particularly relates to a kind of quick union that is used to connect the reducing pipeline.
At present, interconnect between the close and waney pipeline of caliber, or connect between the close pipeline of material difference, external diameter, how processing connection pipe fitting with sleeve pipe or on-the-spot weldering system, labor intensity is big, the accessory heaviness, the construction and installation inconvenience, the interrupt pipe operating time is long.
The purpose of this utility model is to provide a kind of pipe joint that can connect the reducing pipeline fast.
Its technological scheme is: the quick union of a kind of reducing pipeline is characterized in that: it is by reducing bushing 1, seal ring 2,3, gland 4,5, bolt 6 is formed, and reducing bushing 1 is enclosed within on the circular pipe 7,8, seal ring 2,3 is enclosed within respectively on the pipeline 7,8, the interior edge face of seal ring 2,3 is combined closely with the both ends of the surface of reducing bushing 1 respectively, seal ring 2,3 external diameter and exterior edge face respectively with gland 4,5 combine closely, and gland 4,5 is fastening by several bolt 6.
The both ends of the surface of reducing bushing 1 are inner conical, and the oblique interior edge face with seal ring 2,3 matches respectively.
Seal ring 2,3 exterior edge faces both can be vertical surface and also can be the inclined-plane.
Owing to adopted Quick Connect Kit, can shorten the engineering time when therefore constructing at the scene, reduce labor intensity, the interrupt pipe time is short, and is easy for installation rapid.Owing to adopted good Sealing, therefore made sealability improve greatly.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of vertical surface for the seal ring exterior edge face.
Embodiment: reducing bushing 1 is enclosed within on the pipeline 7,8, and rubber seal 2,3 is enclosed within respectively on the pipeline 7,8, and the oblique interior edge face of seal ring 2,3 is combined closely with the two ends inner conical surface of reducing bushing 1 respectively, to form excellent sealing.Seal ring 2,3, external diameter and exterior edge face combine closely with gland 4,5 respectively, gland 4,5 is fastening by several bolt 6, the number of bolt is decided according to the size of pipe diameter, the seal ring exterior edge face can be inclined-plane as shown in Figure 1, also can be vertical surface as shown in Figure 2.Gland and shell material can adopt metal also can adopt rigid plastics according to actual demand.
