Abstract
The utility model relates to an overhead filter of a bypass valve. The overhead filter comprises a filter shell (1), wherein a filter element (2) is arranged in the filter shell (1); and a threaded cover plate (4), which is arranged at the upper part of the filter element (2), is connected with the filter shell (1) in a matching way. The overhead filter of the bypass valve is characterized in that a valve body (6) is arranged between the filter element (2) and the threaded cover plate (4); a valve sleeve (7), which is arranged at the lower end of the valve body (6), is connected with the filter element (2) in a matching way; a sealing gasket (5), which is arranged at the upper end of the valve body (6), is connected with the threaded cover plate (4) in a matching way; and more than one oil hole (61) is relatively arranged on the valve body (6) below the upper end face of the valve sleeve (7). The overhead filter of the bypass valve has the beneficial effect that the bypass valve is arranged between the filter element and the threaded cover plate, so as to solve the problem that the bypass valve at the lower part of the filter is instantly opened, and then pollutants enter each lubricating part along with oil from the bottom to cause the secondary pollution to the engine and damage the engine.
Description
Technical field
The utility model relates to a kind of filter cleaner, especially a kind of bypass valve up-set type filter cleaner.
Background technique
Existing oil filter all is provided with bypass valve on the lower end of filter core, the effect of bypass valve is when engine cold-start, the viscosity of machine oil is big, should not pass through filter paper, or machine oil severe contamination, filter paper is blocked, when machine oil reaches certain pressure, at this moment bypass valve is opened, and machine oil directly enters each lubricant housings, and the cracking pressure difference of bypass valve is 70～250Kpa, after machine oil heats up, machine oil is thinning, and the original resistance of filter core is less than the cracking pressure of bypass valve by filter paper, and at this moment bypass valve cuts out.
Motor car engine is when work, and the machine oil of lubrication system can be constantly dirty, and there are several aspects in the source of pollution, and the one, exogenous impurity, by respirating tube, oil filler etc. locate to enter the bent axle fuel tank as dust in the air; Next is the metal fillings that parts depreciation is got off; Tar asphalt and carbide etc. besides, and these materials are stopped on the filter paper surface by the filter core of oil filter, automobile is in the vibration of when motion and motor self, these materials are vibrated, and are deposited to the outer casing bottom of filter cleaner, after automobile stops to travel once more during ato unit, filter cleaner bypass valve moment opens, these materials are accompanied by machine oil and together enter each lubricated portion from the bottom, motor is carried out secondary pollution, and motor is damaged.
The model utility content
The purpose of this utility model is exactly to be arranged on the defective of filter cleaner bottom in order to overcome existing filter cleaner bypass valve, and a kind of bypass valve up-set type filter cleaner is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
Bypass valve up-set type filter cleaner, comprise filter housing, be provided with filter core in the filter housing, filter core top is provided with thread plate and filter housing is connected, it is characterized in that: between filter core and thread plate, be provided with valve body, valve body lower end is provided with valve pocket and filter core is connected, and the valve body upper end is provided with sealing gasket and thread plate is connected, and is provided with more than one oilhole on respect to the valve body below the valve pocket upper-end surface.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
Described valve body is an annular valve body.
Described valve pocket has the annular valve body, and the outside, lower end of valve sleeve body is provided with a groove and valve body lower end is connected.
Described sealing gasket has annular sealing member, and the outside, upper end of seal is provided with platform and the valve body upper end is connected.
Valve pocket of the present utility model can adopt rubber, exterior-coated nitrile rubber article elastomeric material, the outer wall of valve pocket closely contacts with the inwall of valve body, in the normal state, valve pocket is closely sealed the oilhole of valve body, when pressure difference is 70～250Kpa, pressure presses off valve pocket, machine oil flows into from the valve pocket upper end, size according to the bypass valve cracking pressure, decide the size of the diameter of oilhole, according to the size of rated flow, decision is provided with two, three or four oilholes on valve body, and described oilhole is evenly distributed on the valve body.
The beneficial effects of the utility model are by between filter core and thread plate bypass valve being set, avoided filter cleaner bottom bypass valve moment to open, pollutant is accompanied by machine oil and together enters each lubricated portion from the bottom, motor is carried out secondary pollution, and motor is damaged; Prolong the service time of motor, reduced the wearing and tearing of motor, improved the working life of motor.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a valve body view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model bypass valve up-set type filter cleaner, comprise filter housing 1, be provided with filter core 2 in the filter housing 1, filter core 2 has spring 3 and is connected with filter housing 1 bottom, filter core 2 tops are provided with thread plate 4 and are connected with filter housing 1, be provided with valve body 6 at filter core 2 and 4 of thread plates, valve body 6 is an annular valve body, valve body 6 lower ends are provided with valve pocket 7, the valve sleeve body of valve pocket 7 and valve body 6 suits, the outside, valve sleeve body lower end is provided with a groove and valve body 6 lower ends are connected, valve body 6 upper ends are provided with sealing gasket 5 and are connected with thread plate 4, the seal of sealing gasket 5 and valve body 6 suits, the outside, seal upper end is provided with platform and cooperates with valve body 6 upper ends, on with respect to the valve body 6 below valve pocket 7 upper-end surfaces, be provided with four oilholes 61, four oilholes 61 are evenly distributed on the valve body, the outer wall of valve pocket 7 closely contacts with the inwall of valve body 6, in the normal state, valve pocket 7 is closely sealed the oilhole 61 of valve body 6, when pressure difference is 70～250Kpa, pressure presses off valve pocket 7, and machine oil flows into from valve pocket 7 upper ends each lubricated portion is lubricated.
