Abstract
The utility model relates to a high-pressure oil leakage-preventing pipe joint which is used in an oil pipe of a hydraulic system and is characterized by comprising a flange I (1) and a flange II (2), wherein threaded holes (3) are arranged in the flange I (1) and the flange II (2), the flange I (1) is connected with the flange II (2) through fixed nuts in the threaded holes (3) to form an oil pipe joint, a lug boss (1.1) which is shaped as a trapezoid is arranged in a place of the flange I (1), which is connected with the flange II (2), a pit (2.1) is arranged in a place of the flange II (2), which is connected with the flange I (1), the lug boss (1.1) is matched with the pit (2.1), the flange I (1) or flange II (2) is provided with a plurality of sealing grooves (4) in a place close to the joint, and a sealing ring or sealing gasket is arranged in the sealing groove (4). The high-pressure oil leakage-preventing pipe joint can be used for carrying out effective sealing without causing oil leakage.
Description
Technical field
The utility model relates to a kind of oil connection, relates in particular to a kind of high pressure leakproof oil connection, is used among the oil pipe of hydraulic system.
Background technique
In hydraulic system, be connected the oil connection that all need use all size between oil pipe and oil cylinder, the valve piece, leak in order to prevent oil connection, can come leakproof at increase seal ring between oil connection and oil pipe, oil cylinder, the valve piece or sealing gasket usually.But seal ring or sealing gasket are in use, receive the influence of oil pressure and oil temperature bigger, and be warm when higher when oil pressure and oil, occurs wearing and tearing easily, thereby cause leaking.And oil connection is to form through the flange butt joint, also occurs oil leakage phenomenon between the seam of two flanges easily.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and providing a kind of can effectively seal, high pressure leakproof oil connection that can leakage of oil.
The purpose of the utility model is achieved in that
The utility model high pressure leakproof oil connection comprises flange I and flange II, is equipped with screw on flange I and the flange II; Set screw nut is with flange I and the flange II formation oil connection that joins in the said screw; Said flange I is provided with boss in the joint with the flange II, and said boss is trapezoidal, and said flange II is provided with pit in the joint with the flange I; It is trapezoidal that said pit also is; Said boss matches with pit, and flange I or flange II offer some seal grooves being adjacent to its seam crossing, are provided with seal ring or sealing gasket in the said seal groove.
The utility model high pressure leakproof oil connection has the following advantages:
Oblique setting in the middle of the seam of two flanges that the utility model high pressure leakproof oil connection will dock each other; Can be so that oil can not spill from seam; And begin seal groove at seam crossing and place seal ring or sealing gasket; Improve the sealing of oil connection like this, avoided the generation of oil leakage phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model high pressure leakproof oil connection.
Among the figure: flange I 1, boss 1.1, flange II 2, pit 2.1, screw 3, seal groove 4.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of high pressure leakproof oil connection, comprises flange I 1 and flange II 2; Be equipped with screw 3 on flange I 1 and the flange II 2, set screw nut is with flange I 1 and the flange II 2 formation oil connection that joins in the said screw 3, and said flange I 1 is provided with boss 1.1 in the joint with flange II 2; Said boss 1.1 is trapezoidal, and said flange II 2 is provided with pit 2.1 in the joint with flange I 1, and said pit 2.1 also is trapezoidal; Said boss 1.1 matches with pit 2.1, makes that the flange I 1 and the seam of flange II 2 no longer are straight lines, oblique setting in the middle of the seam; Like this can be so that oil can not spill from seam; And flange I 1 or flange II 2 offer some seal grooves 4 being adjacent to its seam crossing, are provided with seal ring or sealing gasket in the said seal groove 4, can increase the leak preventing effect of oil connection.
