Problems solved by technology

However, in some cases, such as during the installation process, because the distance between the two pipe flanges that need to be installed with flexible rubber joints or the distance between the equipment connection end and the pipe flange at one end is too small, that is, the reserved space If the flexible rubber joint is too small, it is difficult to put in the flexible rubber joint, which will cause a lot of trouble for the installation personnel; or the pipeline system will be displaced, deformed and misaligned during operation, and the flexible rubber joint will be squeezed tightly, but it needs to be disassembled Maintenance, which brings great inconvenience to the maintenance personnel at this time, usually takes a lot of manpower, material resources and time to deal with

Embodiment Construction

[0011] As shown in the figure, the adjustable flexible rubber joint of the present invention includes a corrugated rubber pipe joint body 2 with two connecting end faces 1, and connecting holes 3 uniformly arranged on the connecting end faces 1, Positioning flanges 4 are respectively arranged on the two connecting end faces 1, and the connecting holes 5 on the positioning flanges 4 correspond to the connecting holes 3 on the connecting end faces 1; the two positioning flanges 4 They are connected by length-adjustable telescopic rods. The telescopic rod is composed of two lead screws 6, 7 with opposite helical directions and a screw nut 8 connecting the two lead screws 6, 7. Positioning tubes 9 extending toward the inner diameter of the corrugated rubber pipe joint body 2 are respectively arranged on the inner diameter peripheral surfaces of the two positioning flanges 4 . A rubber liner is arranged on the outer end surface of the positioning flange 4 .

Abstract

A regulatable flexible rubber jointer is composed of a corrugated tubular rubber body with join holes on its both end faces, two locating flanges with join holes relative to the holes on the end of corrugated tubular rubber body, and the length-adjustable telescopic rods for connecting two flanges.

Description

technical field [0001] The invention relates to a flexible rubber joint used for pipeline connection, in particular to an adjustable flexible rubber joint. Background technique [0002] Flexible rubber joints are widely used in pipeline connections to compensate for the linear expansion and contraction of pipelines due to temperature changes, eliminate vibration and noise transmission, and also play a good role in the protection of pipelines and equipment. However, in some cases, such as during the installation process, because the distance between the two pipe flanges that need to be installed with flexible rubber joints or the distance between the equipment connection end and the pipe flange at one end is too small, that is, the reserved space If the flexible rubber joint is too small, it is difficult to put in the flexible rubber joint, which will cause a lot of trouble for the installation personnel; or the pipeline system will be displaced, deformed and misaligned durin...
