Abstract
The utility model provides a high sealed rotary compensator, it includes urceolus (7), inner tube (9), be equipped with sealing filler between urceolus and the inner tube, the right-hand member of urceolus is barrel head board (8), the inner tube stretches into in the urceolus from the barrel head board, pressure cover (2) have been inserted to the left part of urceolus, the pressure cover is overlapped on the inner tube coordinately, the excircle of pressure cover cooperatees with the interior circle of urceolus, sealing filler is located between pressure cover and the barrel head board, the left end of pressure cover radially outwards extends out and presses set flange (3), the left end of urceolus radially outwards extends out urceolus flange (4), bolt (10) run through in and press set flange and urceolus flange, the left end of bolt has screwed. The water flow sealing device has the advantages that the nut is screwed, the pressing sleeve applies pressure to the sealing filler, the pressure of the joint of the sealing filler and the pressing sleeve is the maximum, the joint is the inlet of water flow, the density of the sealing filler at the joint is the maximum, the sealing filler is tightly contacted with the inner pipe, the contact surface of the water flow can be effectively prevented from entering, the sealing filler is prevented from being corroded by water, and the sealing service life is prolonged.
Description
Technical Field
The invention relates to a rotary compensator which is used for compensating expansion with heat and contraction with cold of a hot water pipeline.
Background
The existing rotary compensation structure comprises an outer cylinder and an inner pipe, wherein a boss extends inwards from the wall of the outer cylinder, one end of the inner pipe is inserted into the inner circle of the boss, the other end of the inner pipe is arranged outside the outer cylinder, a sealing filler is arranged between the outer cylinder and the inner pipe, one side of the sealing filler is attached to the end face of the boss, the other side of the sealing filler is pressed by a pressing sleeve, and the sealing filler can expand radially after being pressed, so that the sealing between the outer cylinder and the inner pipe is realized; the defects are that the pressure on the part of the sealing filler close to the lug boss is the minimum, the sealing performance is the worst, water easily enters the sealing filler from the part, and the sealing filler is corroded, so that the sealing performance is gradually reduced.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a high-sealing rotary compensator which can improve the anti-erosion capability of sealing filler and prolong the sealing service life.
The technical scheme includes that the high-sealing rotary compensator comprises an outer cylinder 7 and an inner pipe 9, sealing filler is arranged between the outer cylinder and the inner pipe, and the high-sealing rotary compensator is characterized in that a cylinder bottom plate 8 is arranged at the right end of the outer cylinder, the inner pipe extends into the outer cylinder from the cylinder bottom plate, a pressing sleeve 2 is inserted into the left portion of the outer cylinder and is sleeved on the inner pipe in a pressing sleeve matching mode, the outer circle of the pressing sleeve is matched with the inner circle of the outer cylinder, a sealing ring 5 is arranged between the outer circle of the pressing sleeve and the inner circle of the outer cylinder, the sealing filler is located between the pressing sleeve and the cylinder bottom plate, a pressing sleeve flange 3 extends out of the left end of the pressing sleeve in the radial direction, the left end of the outer cylinder extends out of an outer cylinder flange 4 in the radial direction, a gap is reserved between the pressing sleeve flange and the.
The invention has the advantages that the nut is screwed, the pressing sleeve applies pressure to the sealing filler, the pressure at the joint of the sealing filler and the pressing sleeve is the maximum, the joint is the inlet of water flow, the density of the sealing filler at the joint is the maximum, the sealing filler is tightly contacted with the inner pipe, the contact surface of the sealing filler can be effectively prevented from entering, the sealing filler is prevented from being corroded by water, and the sealing service life is prolonged.

FIG. 1 is a schematic structural diagram of the present invention.
The figures are numbered: 1-connecting pipe, 2-pressing sleeve, 3-pressing sleeve flange, 4-outer cylinder flange, 5-sealing ring, 6-sealing filler, 7-outer cylinder, 8-cylinder bottom plate, 9-inner pipe, 10-bolt and 11-nut.
Detailed Description
The utility model provides a high sealed rotary compensator, it includes urceolus 7, inner tube 9, be equipped with the sealing filler between urceolus and the inner tube, characterized by, the right-hand member of urceolus is barrel head plate 8, the inner tube stretches into in the urceolus from barrel head plate, pressure cover 2 has been inserted to the left part of urceolus, the pressure cover is overlapped on the inner tube coordinately, the excircle of pressure cover cooperatees with the interior circle of urceolus, be equipped with sealing ring 5 between the excircle of pressure cover and the interior circle of urceolus, the sealing filler is located between pressure cover and the barrel head plate, the left end of pressure cover radially outwards extends out pressure cover flange 3, the left end of urceolus radially outwards extends out urceolus flange 4, leave the clearance between pressure cover flange and the urceolus flange, bolt 10 runs through in pressure cover flange and urc.
The nut is screwed, the pressing sleeve applies pressure to the sealing filler, the pressure at the joint of the sealing filler and the pressing sleeve is the maximum, the joint is an inlet of water flow, the density of the sealing filler at the joint is the maximum, the sealing filler is tightly contacted with the inner pipe, the contact surface of the water flow can be effectively prevented from entering, the sealing filler is prevented from being corroded by water, and the sealing service life is prolonged.
The left end opening of the pressing sleeve extends out of the connecting pipe 1, and the connecting pipe and the inner pipe are connected in series with a hot water pipeline when the hot water pipe is used.
