The improved filter with the bypass valve structure is compact in structure, small in number of accessories, simple in assembly, and low in cost.
Description
Technical field
The utility model relates to filter cleaner field, is specifically related to a kind of improved filter cleaner with bypass valve arrangement.
Background technique
Filter is such as the oil filter in vehicle lubricating system, as failed maintenance in time in long-term using process, there will be oil filter seriously to be silted up by impurity, cause the whole oil circuit can not be unimpeded, its result be exactly main oil gallery oil starvation, and motor loses lubricated, cause friction surface to burn because of non lubricant oil, especially the bearing metal of main bearing and connecting rod bearing can run off because friction produces a large amount of heat simultaneously, is even sintered together with axle journal, finally makes engine stop work.For fear of occurring these bad phenomenon, in filter cleaner, be conventionally all provided with a bypass valve, engine oil pressure in the turnover oil duct of filter cleaner is poor while surpassing setting pressure, bypass valve is open, make machine oil can flow directly into without filtration main oil gallery, to guarantee normal lubricated to motor each several part, though the machine oil that enters main oil gallery is not through filtering and do not carry secretly impurity, but can there is not dry friction because lacking to lubricate in motor, occur catastrophe failure.As shown in Figure 1, traditional filter cleaner with bypass valve arrangement generally comprises filter cylinder 01, be arranged on the filter core in filter cylinder 01 and be arranged on the bypass valve in filter cylinder 01, wherein bypass valve is generally by spool 02, open spring 03, valve seat 04 and supported spring 05 form, filter core generally comprises central shaft 07 and is located at the end cover of filter element 06 at central shaft 07 two ends, filter cartridge construction as shown in Figure 2, valve seat 04 is connected and is contained on filter cylinder 01 by buckle, rely on supported spring 05 to hold out against, then end cover of filter element 06 is connected on valve seat 04, this structure not only accessory is more, and because connecting to be contained on filter cylinder 01 and by supported spring 05 by buckle, valve seat 04 holds out against, and end cover of filter element 06 is connected on valve seat 04, buckle joint between valve seat 04 and filter cylinder 01 had both been subject to the gravity of valve seat 04 and filter core, be subject to again the active force of supported spring 05, stressed larger, valve seat easily comes off from filter cylinder 01.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of improved filter cleaner with bypass valve arrangement, and Standard is tight, and accessory is few, and assembling is simple, and cost is low.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the improved filter cleaner with bypass valve arrangement, comprise filter cylinder, be located at filter core and bypass valve in filter cylinder, filter core comprises the central shaft of hollow and is located at the end cover of filter element at central shaft top, end cover of filter element is connected on filter cylinder inwall, and bypass valve is connected on central shaft inwall.
As preferably, end cover of filter element and filter cylinder clamping.
As preferably, end cover of filter element top is provided with snap ring, and filter cylinder upper inside wall is provided with at least two for stretching in snap ring and being stuck in the grab on snap ring inwall, and grab bottom is provided with coupler body, and after grab stretches in snap ring, its upper hook body is towards snap ring internal face.
As preferably, interior one end being connected with end cover of filter element without leave of snap ring reduces gradually to the one end away from end cover of filter element.
As preferably, the bottom of coupler body is provided with bottom-up outward-dipping inclined-plane gradually.
As preferably, bypass valve comprises valve seat and is arranged on the spool on valve seat, and valve seat and central shaft are structure as a whole.
Beneficial effect:
The improved filter cleaner with bypass valve arrangement that the utility model adopts technique scheme to provide, Standard is tight, and accessory is few, assembling is simple, and cost is low, after filter cleaner has assembled, the accessory such as spool, valve seat difficult drop-off, guarantees that filter cleaner normally uses.
