Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.
The utility model discloses a connecting device for installing a valve in a valve well on a pipeline 8, which comprises a hoop body 1, wherein the hoop body 1 tightly holds a valve connecting flange 12 and a pipeline connecting flange 9 of the pipeline 8, and the valve connecting flange 12 is formed at one end part of a valve joint 11; a sealing gasket is arranged between the valve connecting flange 12 and the pipeline connecting flange 9 in a cushioning manner, and a limiting collar 4 is formed on the inner wall of the hoop body 1, is positioned between the valve connecting flange 12 and the pipeline connecting flange 9, and limits the sealing gasket therein. The utility model discloses a theory of operation and advantage lie in: the hoop body 1 of the utility model connects the valve connecting flange 12 and the pipeline connecting flange 9 which are close to each other, the operation of circumferential uniform fastening required by the connection between the flanges is not needed, the fastening connection between the two flanges can be realized only by fastening one end of the hoop body 1, and therefore, the connecting end of the hoop body 1 is only needed to be arranged at the position convenient for operation; during connection between the flanges, a sealing gasket needs to be arranged between the flanges for sealing, in order to avoid the phenomenon that the sealing gasket deviates in position in the fastening process, so that the flow of liquid passing between the two flanges is influenced and the sealing effect is poor, a limiting check ring 4 is constructed on the inner wall of the hoop body 1, and the limiting check ring 4 extends into a position between the valve connecting flange 12 and the pipeline connecting flange 9, so that the sealing gasket is limited in the limiting check ring; to sum up, the utility model discloses a valve installation is dismantled simply, makes things convenient for later maintenance's purpose.
As a preferred embodiment of the present invention, the hoop body 1 includes two structures. First, as shown in fig. 1 and 3, the band body 1 is made of an elastic material and has two free ends adjacent to each other, a fastening lug 3 is formed on each free end, the two fastening lugs 3 are connected by fastening bolts 7, and an operator connects the valve connecting flange 12 and the pipe connecting flange 9 by tightening the fastening bolts 7. Secondly, the hoop body 1 can also be made of a rigid material, specifically, as shown in fig. 3, the hoop body 1 includes two half hoop bodies, each half hoop body is of an arc-shaped structure, one end of each half hoop body is pivoted through a rotating shaft 5, and the other ends of the two half hoop bodies are connected through a fastening bolt 7.
As a preferred embodiment of the present invention, in order to realize the position limitation of the sealing rings of different types, as shown in fig. 3 to 6, an annular groove 6 is formed on the inner wall of the hoop body 1, and the outer edge of the position-limiting retainer ring 4 of the corresponding type is assembled in the annular groove 6; wherein, spacing retaining ring 4 is made for elastic material, and it is the annular structure who has the opening of its inner wall of intercommunication and outer wall, and the in-process that the hoop body 1 was tightened to operating personnel like this, spacing retaining ring 4 also takes place elasticity and inwards deforms to restrict the sealing washer in it, can not break away from the constraint of annular groove 6 simultaneously.
