Eccentric clamp

An eccentric and clamping technology, which is applied in the direction of pipe supports, pipes/pipe joints/fittings, mechanical equipment, etc., can solve problems such as joint position deviation, leakage, and interface axis position deviation, so as to reduce sealing points and leakage point, reduce manufacturing cost, and reduce the effect of clamp deformation

Problems solved by technology

[0004] The purpose of the invention provided by the present invention is to provide an eccentric clamp, which solves the problem of the position deviation of the two connected joints of the pipeline or pipe fittings, or the displacement of the pipeline or pipe fittings when the pressure and temperature change cause the axial center of the interface The position deviation causes the connection part to bear additional load and the problem of leakage occurs

Abstract

The invention provides an eccentric clamp. The eccentric clamp is composed of a square hole hoop semi-ring, an eccentric sealing ring, a round hole hoop semi-ring, a round-head square-neck bolt and a nut, and the square hole hoop semi-ring, the round hole hoop semi-ring and the eccentric sealing ring are each provided with an upper circular ring locking face and a lower circular ring locking face which are not coaxial and a sealing face, the axial distance between each circular ring locking face and the sealing face is t, the square hole hoop semi-ring and the round hole hoop semi-ring are installed at the upper end and the lower end of the eccentric sealing ring and connected through the round-head square-neck bolt, and the nut is in threaded connection with the outer portion of the bottom end of the round-head square-neck bolt. The eccentric clamp provided by the invention solves the problem of position deviation of two connected joints of a pipeline or a pipe fitting, or solves the problem that the pipeline and the pipe fitting displace when the pressure and the temperature change to cause the position deviation of the axis of the joint, so that the connecting part bears extra load and leaks.

Description

technical field [0001] The invention relates to the technical field of connection of pipes and pipe fittings, in particular to eccentric clamps. Background technique [0002] The circular-arc holding surface of the existing two-sided snap-in pipe joint of the clamp requires that the two connected interfaces be concentric, that is, on the same cylindrical surface. When there is a deviation in the axis line of the pipe joint of the two connected pipe fittings or pipelines, the adjustment ability is poor and the installation is difficult. In addition, in some installation structures where the pipelines are connected to each other, due to the pressure and thermal expansion of the pipelines, the axial centers of the two connecting pipe joints will also be displaced, causing the clamp joints to bear additional loads, deform and easily leak or damage parts. as attached Figure 5 As shown in the figure on the left, when the distance between the two interfaces G1 on the pipe or fit...
