Abstract
The utility model relates to a sealing device for a double-screw air compressor. The sealing device is characterized in that a pipe joint fixedly arranged at the end part of an oil pipe is comprised; the back side of the pipe joint is sheathed with a moveable flange connected with a fixed flange fixed on a sealed member; and a sealing rubber cushion is arranged at the side of the pipe joint, which is close to the fixed flange. The structure adopts the flange seal so as to allow a plurality of installations, without affecting the sealing effect. If a sealing rubber cushion is damaged, only the sealing rubber cushion is taken down to be replaced by a new sealing rubber cushion, and the replacement is convenient and does not affect the sealing effect; therefore, the utility model has the advantages of simple structure, good sealing effect, convenient installation and disassembly, and the like.
Description
Technical field
The utility model relates to a kind of good sealing effect, the seal arrangement that is used for double-screw air compressor simple in structure.
Background technique
At present, mainly be to connect between the double-screw air compressor oil pipe by threaded pipe, must be used thread locking adhesive simultaneously and seal when threaded pipe is installed, adopt this sealing means to cause sealer to push in installation process easily and enter sealed, phenomenon results in blockage; Adopt to be threaded in addition and be unfavorable for repeatedly installing, because in the process of dismounting screw thread, do solid easier being retained in the screw thread of sealer, sealer will enter in the system when installing again, and when being threaded, be difficult to remedy because the bad oil leakage phenomenon that causes is installed.
Summary of the invention
The utility model provides a kind of good sealing effect, the seal arrangement that is used for double-screw air compressor simple in structure for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of seal arrangement that is used for double-screw air compressor, it is characterized in that: comprise the pipe joint that installs with oil pipe end, rear side at pipe joint is set with loose flange, and loose flange connects the fastening flange that is packed on sealed, is provided with seal rubber pad at pipe joint near the fastening flange side.
Advantage and the good effect that the utlity model has are: since double-screw air compressor be fixed with pipe joint at oil pipe end, rear side at pipe joint is set with loose flange, loose flange connects the fastening flange that is packed on sealed by bolt, is provided with seal rubber pad at pipe joint near the fastening flange side.Compress loose flange by bolt like this, make seal rubber pad be close on the fastening flange, solved the purpose of sealing effectively, avoided other impurity to enter the normal operation that unit influences unit; Adopt flange seal repeatedly to install in addition, all can not influence sealing effect.After if seal rubber pad damages, only need seal rubber pad is taken off, change a new seal rubber pad again and get final product, and change conveniently, so said structure has advantages such as simple in structure, good sealing effect, easy installation and removal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, oil pipe; 2, loose flange; 3, pipe joint; 4, fastening flange; 5, seal rubber pad; 6, sealed; 7, bolt.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, be fixed with pipe joint 3 in oil pipe 1 end, be set with loose flange 2 at the rear side of pipe joint 3, loose flange 2 is packed in fastening flange 4 on sealed 6 by bolt 7, is provided with seal rubber pad 5 at pipe joint 3 near fastening flange 4 sides.The loose flange 2 that compresses by bolt 7 makes seal rubber pad 5 be close on the fastening flange 4 like this, has solved the purpose of sealing effectively, has avoided other impurity to enter the normal operation that unit influences unit; Because pipe joint 3 back side flanges adopt loose flange, can remedy owing to add the error of bringing man-hour in addition by regulating loose flange 2; Adopt flange seal repeatedly to install, all can not influence sealing effect.After if seal rubber pad damages, only need seal rubber pad is taken off, change a new seal rubber pad again and get final product, and change conveniently, so said structure has advantages such as simple in structure, good sealing effect, easy installation and removal.
