Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1-3, a strainer convenient to detach, including valve body 1, filter equipment 2, blowoff valve 3 of Y type structure, valve body 1 is equipped with oil feed end 11 and play oily end 12, the one end and the blowoff valve 3 of filter equipment 2 are connected, the other end grafting of filter equipment 2 is in the cavity between oil feed end 11 and play oily end 12 of valve body 1, blowoff valve 3 is including gland nut 31, the blowdown nut 32 that is used for controlling the blowdown that is used for sealed cavity exit end, blowdown nut 32 passes through threaded connection on gland nut 31, the one end and the gland nut 31 of filter equipment 2 are connected.

Under this kind of design, engine oil gets into from the oil feed end 11 of valve body 1 earlier, reentrant oil feed end 11 and go out in the cavity between the oil end 12, and engine oil can filter through the air device in the cavity, engine oil flows out by the oil end 12 of valve body 1 at last, because engine oil flow direction and impurity can receive gravity's influence, impurity can pile up in filter equipment 2's bottom at last, impurity that piles up in the bottom can clear up through unscrewing blowdown pile of blowoff valve 3, can unscrew gland nut 31 when need wash filter equipment 2.
