Description
Technical field
The utility model relates to the bypass Decompression valves field for automobile turbocharger, particularly a kind of seal arrangement of bypass Decompression valves.
Background technique
In recent years, turbosupercharger because HP, hp/litre can be improved, improve the discharge of motor, improve fuel economy, reduce oil consumption and obtain the favor of people.Turbocharger operation principle is: engine exhaust drives supercharger rotor to rotate, and air compressing is delivered to cylinder and fuel oil mixed combustion, improves engine output.And bypass Decompression valves plays the linkage function on the pressure side and between air inlet side at turbocharger supercharged pump.When automobile emergency slows down, by this valve, boost pressure end and inlet end are set up short circle, reach pressure release, protection pressurized machine; Supercharger speed can also be stablized, so that switch to acceleration mode rapidly simultaneously.Generally that the sealing means sealed by lip sealing ring cylindrical side is realized between the valve closed shape of existing bypass Decompression valves and guard shield, but problem is, in the process of the upper and lower motion of valve closed shape, the locating effect of lip seal is bad, easily shake or be shifted, also can affect sealing effect.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of seal length suitable, can effectively avoid lip seal to shake, good sealing effect, the seal arrangement of the bypass Decompression valves of lip seal good positioning effect.
The technical scheme in the invention for solving the above technical problem is: a kind of seal arrangement of bypass Decompression valves, comprise plastic shell, the valve closed shape that can be driven by electromagnetic unit and the movable guard shield being sleeved on valve closed shape periphery, lip seal is provided with between described valve closed shape and guard shield, the both sides of described lip seal are respectively equipped with the first supporting leg for matching with valve closed shape and the second supporting leg for matching with guard shield, the outer circumferential face of described guard shield is provided with the positioning block for positioning the first supporting leg of lip seal, and the lower end of described plastic shell is provided with the positioning convex ring for positioning the second supporting leg of lip seal.
Compared with prior art, the utility model has the advantage of: the seal arrangement of this bypass Decompression valves the outer circumferential face of guard shield be provided with positioning block for positioning the first supporting leg of lip seal, and the lower end of plastic shell is provided with the positioning convex ring for positioning the second supporting leg of lip seal.Like this, also can be positioned lip seal by positioning block and arranging of positioning convex ring in the process of the upper and lower motion of valve closed shape, prevent lip seal from shaking or be shifted, sealing effect is better.
As preferably, the length of the second described supporting leg is 0.9 ~ 1.8 times of the length of the first described supporting leg.Like this, sealing effect is better.
As preferably, the second described positioning convex ring and described plastic shell integrated injection forming.Like this, construction cost is low, and it is also more reasonable to arrange.
As preferably, the bottom of the outer circumferential face of described guard shield is provided with the protuberance of annular.Like this, valve closure function can better be realized.
As preferably, described guard shield is sealedly attached to the lower end of described plastic shell.
As preferably, the periphery diameter taper convergent successively from top to bottom in the stage casing of described valve closed shape.Like this, can effectively reduce frictional force, the sealing effect preventing excessive wear from causing is deteriorated.
As preferably, the tapering in described valve closed shape stage casing is 0 ~ 1.5 °.Like this, can effectively reduce frictional force, the sealing effect preventing excessive wear from causing is deteriorated.
