Abstract
The invention relates to a divided-plate ring type sealing deivce which comprises a gland (1), a shaft sleeve (2), a sealing ring outer ring (3), a sealing ring inner ring (4), a tension spring (5) and a sealing ring positioning dowel pin (6), wherein the sealing ring outer ring (3) and the sealing ring inner ring (4) are respectively formed by three plates in combined mode, and the sealing ring inner ring (4) is arranged in a spigot groove (32) disposed at the side end of the sealing ring outer ring (3). Split matched axial gaps and radial gaps of the three-plate sealing ring inner ring and the three-plate sealing ring outer ring are sealed in staggered shielding mode so that media are effectively prevented form leaking along the gaps, good sealing performance is achieved, the sealing requirements are met simply through one group of sealing, and the installation space is reduced.
Description
Technical field
What the present invention relates to is the distinguish ring type sealing device, particularly blower fan axle distinguish ring type sealing device.
Background technique
The distinguish ring type sealing device is usually used in sealing as axle in the various blower fans, prevents dielectric leakage.As shown in Figure 1, the seal ring of this seal arrangement is to hold the annulus that is combined into tightly by extension spring by three lobe ring bodies, seal ring is installed in the seal groove of offering on the gland, inner ring surface and the axle sleeve of seal ring are slidingly matched, medium is carried out axial shutoff, and pressure medium effect simultaneously is adjacent to the vertical plane of the vertical plane of branch seal ring and gland medium is carried out radially shutoff.
This seal arrangement is in order just to change the seal ring of rapid wear under not dismounting equipment, so gland constitutes for dividing two halves, seal ring is divided into three lobe rings and constitutes.Because seal ring is that branch three lobes constitute, so involutory slit is arranged between two lobes, therefore medium can from axially and radially along this slit to external leakage, particularly when temperature raises, because heat expansion enlarges this slit, leakage rate can only be to adopt 2-3 group seal ring to use side by side in order to reduce this leakage, to reach the leak-tight seal requirement along with increase also.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art and improve, provide a kind of simple in structure, manufacture method, the distinguish ring type sealing device of good airproof performance.
Distinguish ring type sealing device of the present invention comprises gland 1, axle sleeve 2, seal ring outer shroud 3, ring 4 in the seal ring, extension spring 5, seal ring positioning dowel 6, seal ring outer shroud 3 is that three lobes constitute, have the extension spring mounting groove at seal ring outer shroud 3 outer ring surfaces, extension spring 5 is installed in this mounting groove the seal ring outer shroud 3 of three lobes combination is held tightly, side at seal ring outer shroud 3 has seam groove 32, namely have ring 4 mounting grooves in the seal ring, ring 4 is that three lobes constitute in the seal ring, ring 4 cooperates and is installed in the seam groove 32 that seal ring outer shroud 3 sides offer in the seal ring of three lobes combinations, seal ring outer shroud 3 is installed in the seal ring groove of offering on the gland 1 12, ring 4 and seal ring outer shroud 3 cooperates anchor ring to have the fixing pin 6 of anti-rotation positioning groove 40 and gland 1 outside end face to cooperate, carry out the rotation inhibiting restriction to encircling 4 in seal ring outer shroud 3 and the seal ring in seal ring.For further improving fruit of sealing, have labyrinth seal groove 35 at the inner ring surface 34 of seal ring outer shroud 3 and cooperate axial seal with axle sleeve 2, have labyrinth seal groove 37 at 36 of the side rings of seal ring outer shroud 3 and cooperate radial seal with seal ring groove 12 side end faces on the gland 1.
The present invention has adopted ring 4 structural types that match in seal ring outer shroud 3 and the seal ring, closely paste mutually with 32 of the seam grooves of outer ring surface with seal ring outer shroud 3 side end face of ring 4 in the seal ring, make the involutory axial and radial gap dislocation of the interior outer seal ring of three-clove style block sealing, thereby effectively stop medium along the leakage in slit, the left end face of ring 4 is close in pressure medium effect lower sealing ring outer shroud 3 seam grooves 31 and seal ring, effectively prevents the radial leakage of medium.The inner ring surface of seal ring outer shroud 3 and the interior ring 4 of seal ring adopts different matching relationships to carry out double seal with axle sleeve 2, effectively prevents the axial leakage of medium.
Therefore good airproof performance of the present invention only just can guarantee seal request with one group of sealing, and prior art need be used many group ring seal rings relatively, simplifies the structure, and is easy to install, dwindled installing space, reduced cost.
