Beneficial effect
1, since the fluid media (medium) of certain pressure is after filter element filtering, there are problems that secondary pollution, to overcome the problems, such as this, filtering
Increase a strainer inside the filter core of clear device and be further added by one of filtering that is, before fluid media (medium) enters engine lubricating road, with
The filter core PP cotton fiber of the fracture of fluid media (medium) outflow is adequately filtered out, and is avoided the secondary pollution to engine lubricating road, is prevented
Damage is brought to car engine.
2, after equipment completes cleaning function, directly top cover can be unscrewed with hand, takes out filter core, it is entirely avoided fluid is situated between
Matter is overflowed inside filter, easy to operate；Since the closed volume space of the filter is small, storing up in closed volume space
It is few that long-pending fluid media (medium) discharges the required time, saves the time for user, improves efficiency.
3, top cover of the present invention is efficiently solved in assembling process, top cover should be determined using tapered sleeve positioning, clamping and sealing
Position clamps and seals filter core, while compressing the assembly closed-loop problem of O-ring seal again.
It is unique, reasonable, simple that the present invention designs, it may also be used for the filtration, purification of other fluid media (medium)s such as fuel oil.
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.
