Abstract
The utility model relates to a by-pass valve or check valve that is used for an oil filter, which comprises a thin-wall valve base with a movable valve core and corresponding compression spring; wherein, a plurality of elastic long hooks aligned centrally on the sealing end face of the movable valve core, and the elastic long hooks run across the valve base; the compression spring is fitted between the neck-out part of the elastic long hooks and the valve base; in that way, the components form a disassemble structure. The utility model can be assembled without welding or riveting; instead, the utility model can be assembled simply by placing the movable valve core on the valve base and then fitting the compression spring onto the elastic long hooks; therefore, the utility model can be assembled manually in a simple and convenient manner without any tool; furthermore, since the sealing surface of the movable valve core is tensioned and sealed by the compression spring evenly, no oil leakage will occur, and the sealing is reliable.
Description
Technical field: the utility model relates to bypass valve or the safety check that a kind of oil filter is used.
Background technique: in oil filter, generally be provided with bypass check valve, use as full by-pass relief valve when being contained in the filter core bottom, use as one way stop peturn valve when being contained in filter core top.General bypass check valve all is that movable spool and pressure spring are contained in the support, then with support welding or be riveted on the valve seat manufacturing process complexity, assembling is inconvenient, and movable spool is compressed spring and is pressed on the valve seat and seals, and pressure is inhomogeneous, the leakage of oil amount is big, and is reliable inadequately.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of production to assemble oil filter bypass check valve simply and easily.
The utility model comprises the valve seat of thin-walled type, valve seat is provided with movable spool and corresponding pressure spring, the seal face of movable spool is provided with several centrally disposed elasticity long hook foots, the elasticity long hook foot crosses valve seat, and pressure spring then is enclosed within turning up of each elasticity long hook foot and cooperates formation detachable type structure between part and the valve seat.
The utility model assembling need not welding or riveted joint, being inserted in pressure spring after being placed on movable spool on the valve seat on the elasticity long hook foot gets final product, can adorn by hand and take, do not need other industry equipment, assemble simple and conveniently, and the sealing surface of movable spool is compressed spring tension sealing, tension uniform, not easy oil leakage seals more reliable.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation;
Fig. 2 is another structural type schematic representation of embodiment.
Embodiment: as shown in the figure, be provided with movable spool 2 and corresponding pressure spring 4 on the valve seat 1 of thin-walled type, the seal face of movable spool 2 is provided with several centrally disposed elasticity long hook foots 3, and present embodiment adopts four.Elasticity long hook foot 3 crosses valve seat 1, and 4 of pressure springs are enclosed within turning up of each elasticity long hook foot 3 and cooperate formation detachable type structure between part and the valve seat 1.Assembling or dismounting all can directly be adorned by hand and take, and be simple and convenient.During use, the structural type of Fig. 1 is full by-pass relief valve, is contained in the filter core bottom of filter cleaner, and when filter core obstruction and starting a cold engine, machine oil can back down movable spool 2 and enter the vehicle lubrication system.Structural type as Fig. 2 is one way stop peturn valve, is contained in filter core top, prevents that machine oil from refluxing.
