Abstract
The invention provides a kind of filter cleaner of band bypass valve arrangement of improvement, the bypass valve comprising filter cylinder, be arranged on the filter core in filter cylinder and be arranged in filter cylinder, bypass valve is arranged in filter core, filter core is arranged in filter cylinder, filter core comprises the central shaft of hollow and is located at the end cover of filter element of central shaft end, and bypass valve is arranged in central shaft.Standard of the present invention is tight, and accessory is few, and assembling is simple, and cost is low.
Description
Technical field
The present invention relates to filter cleaner field, be specifically related to a kind of filter cleaner of band bypass valve arrangement of improvement.
Background technique
Oil filter in filter such as vehicle lubricating system, as failed maintenance in time in Long-Time Service process, there will be oil filter seriously to be silted up by impurity, cause whole oil circuit can not be unimpeded, its result be exactly main oil gallery oil starvation, and motor loses lubrication, friction surface is caused 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.In order to avoid there is these bad phenomenon, usually a bypass valve is all provided with in filter cleaner, when engine oil pressure difference in the turnover oil duct of filter cleaner exceedes setting pressure, namely bypass valve is open, make machine oil can flow directly into main oil gallery without filtration, to ensure the normal lubrication to motor each several part, though the machine oil entering main oil gallery does not carry impurity secretly through filtering, but can not there is dry friction because lacking lubrication in motor, occur catastrophe failure.As shown in Figure 1, the filter cleaner of traditional band bypass valve arrangement generally comprises filter cylinder 01, the bypass valve being arranged on the filter core in filter cylinder 01 and being arranged 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 contained on filter cylinder 01 by buckle connection, supported spring 05 is relied on 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 to be contained on filter cylinder 01 because valve seat 04 is connected by buckle and to be held out against by supported spring 05, and end cover of filter element 06 is connected on valve seat 04, bayonet 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 by this invention is the filter cleaner of the band bypass valve arrangement providing a kind of improvement, and Standard is tight, and accessory is few, and assembling is simple, and cost is low.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: the filter cleaner of the band bypass valve arrangement of improvement, comprise filter cylinder, be located at filter core in filter cylinder and bypass valve, 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 and is provided with coupler body for stretching in snap ring and the grab be stuck on snap ring inwall bottom grab, and grab to stretch into after in snap ring its upper hook body towards snap ring internal face.
As preferably, interior one end be 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 inclined-plane outward-dipping 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 filter cleaner of the band bypass valve arrangement of the improvement that the present invention adopts technique scheme to provide, Standard is tight, and accessory is few, and assembling is simple, and cost is low, and after filter cleaner has assembled, the accessory such as spool, valve seat difficult drop-off, guarantees that filter cleaner normally uses.
