Abstract
The invention relates to a radial dual end surface mechanical sealing device, comprising a pair of movable ring (1) and fixed ring (2) which are mutually matched. The invention is characterized in that the matching end surface of the movable ring (1) and the fixed ring (2) is correspondingly provided with cirque concave troughs (10, 20) which form two radially matched friction pairs; the fixed ring (2) is provided with a flow discharging ring (21), thus forming the radial dual end surface mechanical seal; the movable ring (1) is connected with a shaft sleeve (3) on the matching of an auxiliary sealing ring; the fixed ring (2) is matched and connected with an end cover on the matching of the sliding auxiliary sealing ring; the bottom of the fixed ring installation trough on the end cover (6) is provided with springs (5) which push the rear end of fixed ring (2) for compensation; with simple and compact integrated structure, small structure space and convenient installation and application, the invention is especially suitable for the sites where the radial installation dimensions are restricted.
Description
Technical field
What the present invention relates to is mechanical seal device, is a kind of seal arrangement that prevents that working fluid from leaking along running shaft.
The prior art situation
Mechanical seal device claims face seals again, by at least one pair of rotating ring and stationary ring perpendicular to axis, and rotating ring its end face and stationary ring end face keep the applying slip formation that is rotatably assorted down in elastic compensating (bellows or spring) mechanism effect.Rotating ring is connected with shaft drive, and stationary ring is connected with end cap, pays the slide relative rotation by rotating ring and stationary ring friction and finishes the rotation axis seal effect.
Radial direction double end-face mechanical sealing device of the prior art, no matter be that rotating ring or stationary ring are as compensated loop, compensated loop all is that two split rings by inside and outside setting constitute, compensated loop cooperates with the uncompensated ring end face and forms radially two friction fit and pay, and corresponding respectively two compensated loops are provided with individual compensation mechanism certainly, form radial double mechanical seal, though it has the technique effect of oneself, but its overall structure space is bigger, radial dimension is big, inconvenience is installed, and influence is installed and used on equipment, and its application is also therefore limited.
Summary of the invention
The objective of the invention is to improve, a kind of compact structure that has is provided, use radial direction double end-face mechanical sealing device easy for installation at above-mentioned the deficiencies in the prior art.
Technological scheme of the present invention is to include a pair of rotating ring that cooperatively interacts 1 and stationary ring 2, correspondence offers ring groove 10 on rotating ring 1 and stationary ring 2 counterfaces, 20, making the counterface of rotating ring 1 and stationary ring 2 form radially two friction fit pays, ring groove 20 on the corresponding stationary ring 2 axially offers discharge orifice 21 on stationary ring 2, be that rotating ring 1 forms radial double mechanical seal with stationary ring 2, rotating ring 1 is at auxiliary seal ring 12,13 cooperate down with axle sleeve 3 on the mounting groove offered be connected, stationary ring 2 is at slippage auxiliary seal ring 22,23 cooperate down with end cap 6 on the mounting groove offered be connected, the bottom of the stationary ring mounting groove on end cap 6 is distributed and is provided with spring base hole 61 and spring 5, and spring 5 ejections act on stationary ring 2 rear ends and carry out the stationary ring compensation.
The present invention adopts the overall structure fastness, structural strength is good, the counterface distortion is little, stationary ring 2 as compensated loop is a monocycle, and corresponding its is provided with spring 5 compensation mechanisms, and its overall structure is simply compact, structure space is little, radial structure and installation dimension are little, and be easy to install, is specially adapted to radially installation dimension occasions with limited use.
