Abstract
The invention relates to a rotation compensator used for compensating thermal expansion and chilling contraction of pressure pipes with steam and hot water as media. The rotation compensator comprises an outer barrel and an inner pipe (4). A reducer pipe (1) is arranged on the left side of a barrel body (2) of the outer barrel. A flange (3) is arranged on the right side of the barrel body. The rotation compensator is characterized in that a barrel cap (11) is in seal connection with the flange; a pipe body on the upper left side of the barrel cap extends into the barrel body; the left end of the inner pipe is placed in the barrel body, and the right end of the inner pipe extends out of the pipe body of the barrel cap; the two ends of a silica rubber pipe (5) are connected with the left end of the inner pipe and the pipe body of the barrel cap in a sealed mode; a gap is reserved between the silica rubber pipe and the inner wall of the outer barrel. Compared with the prior art, when the inner pipe and the outer barrel rotate relatively, the silica rubber pipe connected with the inner pipe and the barrel cap is reversed; due to the fact that the gap is reserved between the silica rubber pipe and the inner wall of the outer barrel, the friction force between the silica rubber pipe and the inner pipe is small, and the silica rubber pipe is barely abraded, and thus the seal property of the rotation compensator can be maintained.
Description
Technical field
The present invention relates to a kind of whirl compensator, for compensation medium be steam, the expanding with heat and contract with cold of the pressure piping of hot water.
Background technique
The structure of existing whirl compensator comprises urceolus and interior pipe, a part for interior pipe is placed in urceolus, the stuffing box packing of ring-type is pressed with between interior pipe and the intersection of urceolus, whirl compensator is arranged in pressure piping, when pressure piping expands with heat and contract with cold, the interior pipe of whirl compensator is relative with between urceolus to be rotated, and realizes the thermal stress compensation to pressure piping.Interior pipe is relative with between urceolus when rotating, stuffing box packing and produce very large frictional force between interior pipe and urceolus stuffing box packing is worn and torn, and whirl compensator sealability can decline gradually, has influence on the working life of whirl compensator.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of whirl compensator, to reduce the wearing and tearing of Sealing, keeps sealability.
This whirl compensator comprises urceolus and interior pipe 4, the left side of the cylindrical shell 2 of urceolus is provided with reducer pipe 1, the right side of cylindrical shell is provided with flange 3, it is characterized in that, flange is sealedly connected with cover 11, the body of cover upper left side is stretched in cylindrical shell, the left end of interior pipe is placed in cylindrical shell, the right-hand member of interior pipe passes from the body of cover, and the two ends of silicone rubber tube 5 are sealedly connected on the left end of interior pipe and the body of cover respectively, leave gap between silicone rubber tube and the inwall of urceolus.
Compared with prior art, when interior pipe is relative with between urceolus rotate time, the silicone rubber tube be connected on the body of interior pipe and cover produces and reverses, because the inwall of silicone rubber tube and urceolus leaves gap, frictional force between silicone rubber tube and interior pipe is very little, silicone rubber tube produces wearing and tearing hardly, can keep the sealability of whirl compensator.Silicone rubber tube is in compensator in addition, and the impact of the oxygen in light and air is very little to be not easy aging, and its operating life can reach many decades.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right elevation of Fig. 1.
Mark in accompanying drawing represents respectively: pipe, 5-silicone rubber tube, 6-clip, 7-stop collar, 8-position-arresting disk, 9-bolt, 10-sealing gasket, 11-cover in 1-reducer pipe, 2-cylindrical shell, 3-flange, 4-.
Embodiment
Existing accompanying drawings the specific embodiment of the present invention.
This whirl compensator comprises urceolus and interior pipe 4, urceolus is made up of reducer pipe 1, cylindrical shell 2, flange 3, and the left side of the cylindrical shell 2 of cylindrical shell is reducer pipe 1, and the right side of cylindrical shell is flange 3, cover 11 will be connected on flange by bolt 9, be provided with sealing gasket 11 between cover and flange; The body of cover upper left side is stretched in cylindrical shell, the left end of interior pipe is placed in cylindrical shell, the right-hand member of interior pipe passes from the body of cover, and the two ends of silicone rubber tube 5 are sealedly connected on the left end of interior pipe and the body of cover respectively, leave gap between silicone rubber tube and the inwall of urceolus.The internal diameter of described reducer pipe is equal with the internal diameter of interior pipe.
When medium fluid is passed through from urceolus and interior pipe, silicone rubber tube seals, and stops medium fluid to spill along the gap between interior pipe and the body of cover.Urceolus, when internally pipe rotates mutually (angle of rotation is between-25 degree are to 25 degree), because silicone rubber tube is flexible body, can reverse with urceolus or interior pipe freely.The operating ambient temperature of silicone rubber tube is-20 DEG C to 330 DEG C.
The external diameter of left end of described interior pipe is equal with the external diameter of the body of cover, the external diameter of the left end of interior pipe is greater than the external diameter of its right-hand member, leave the gap of 1 millimeter of scope between the end face of the reducing face of interior pipe and the body of cover, the cylindrical of the inwall of silicone rubber tube and the body of interior pipe and cover fits; Medium fluid can be passed to the body of interior pipe and cover like this to silicone rubber tube pressure, strengthen the voltage endurance capability of silicone rubber tube.
Silicone rubber tube can be connected with the body of high temperature adhesive with interior pipe and cover; Annular groove can be set at the body of interior pipe and cover, by clip 6, silicone rubber tube be tied tight in annular groove.
This whirl compensator also comprises a limit stoper, limit stoper comprises stop collar 7, position-arresting disk 8, stop collar is through on bolt 9, stop collar is made up of body and flange, adjacent on the right side of the body of stop collar and cover, on inner pipe, the body of stop collar is in the periphery of position-arresting disk in position-arresting disk welding, the flange of stop collar reaches in the circumference of position-arresting disk, when stop collar is tightened by bolt upper cap nut the reducing face of interior pipe and the body of cover end face between leave the gap of 1 millimeter of scope.This limit stoper can prevent from producing larger axial float between urceolus and interior pipe, avoids making silicone rubber tube be subject to a tensile force or compressive force when whirl compensator is installed on pressure piping.
