Abstract
For solving technical problems, the utility model adopts a scheme that a diesel engine oil passage pressure limiting structure comprises a pressure-limiting valve main body, wherein a steel ball for closing or opening an oil passage is arranged inside the pressure-limiting valve main body, and is arranged at the upper part of a pressure-limiting spring, the pressure-limiting spring is arranged on a circular spring seat, the limiting structure further comprises a cotter pin for limiting the position of the spring seat, and the upper end of the pressure-limiting valve main body is provided with external threads; the diesel engine oil passage pressure limiting structure has the benefits that the structure is simple, the mounting is convenient, and oil pressure balance inside an engine body can be ensured.
Description
Technical field
The utility model relates to mechanical field, specifically a kind of diesel engine oil duct pressure limiting structure.
Background technique
Lubricated is a large system of motor, and its existing lubrication has again clean and cooling action.Diesel-engine body is provided with many places oil duct, in order to prevent that lubricating system oil pressure is too high, increase engine power consumption, cause the place's leakage of oil etc. that is tightly connected in oil circuit, therefore need be provided with pressure-limit valve on oil duct, its effect is the oil pressure of restriction lubricating system, makes it be no more than specified value.
Model utility content
The utility model object is to provide the oil pressure that a kind of diesel engine oil duct pressure limiting structure limits lubricating system, makes it be no more than specified value.
The utility model technical solution problem provides following scheme: a kind of diesel engine oil duct pressure limiting structure, comprise pressure-limit valve main body, in described pressure-limit valve main body, be provided with for sealing or open the steel ball of oil duct, described steel ball is located at pressure limiting spring upper end, described pressure limiting spring is located on ring spring seat, described pressure limiting structure also comprises the cotter pin that limits spring seat position, and the upper end of described pressure-limit valve main body is provided with outside thread.
As optimization: the outer side wall of described pressure-limit valve main body lower end is positive six prism structures.
The beneficial effects of the utility model are: the utility model is simple in structure, easy for installation, have guaranteed oil pressure balance in body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, pressure-limit valve main body, 2, steel ball, 3, pressure limiting spring, 4, spring seat, 5, cotter pin, 6, outside thread.
Embodiment
As shown in Figure 1, a kind of diesel engine oil duct pressure limiting structure, comprise pressure-limit valve main body 1, in described pressure-limit valve main body 1, be provided with for sealing or open the steel ball 2 of oil duct, described steel ball 2 is located at pressure limiting spring 3 upper ends, and described pressure limiting spring 3 is located on ring spring seat 4, and described pressure limiting structure also comprises the cotter pin 5 that limits spring seat 4 positions, the upper end of described pressure-limit valve main body 1 is provided with outside thread 6, and pressure-limit valve main body 1 is anchored on body oil duct place by upper external screw thread 6.
The utility model work is as follows: pressure-limit valve main body 1 is screwed into body oil duct place by outside thread 6, and when in engine oil path, oil pressure surpasses specified value, steel ball 2 is open, and compression pressure limiting spring 3 flows back to oil sump place by unnecessary lubricant oil, and oil pressure is reduced.Oil pressure is higher, and steel ball 2 apertures are larger, and the lubricant oil that flows back to oil sump is more, and oil pressure also declines manyly.When lubricating system oil pressure drops to normal pressure, steel ball 2 just resets under the effect of pressure limiting spring 3.
Claims (2)
1. a diesel engine oil duct pressure limiting structure, comprise pressure-limit valve main body, it is characterized in that: in described pressure-limit valve main body, be provided with for sealing or open the steel ball of oil duct, described steel ball is located at pressure limiting spring upper end, described pressure limiting spring is located on ring spring seat, described pressure limiting structure also comprises the cotter pin that limits spring seat position, and the upper end of described pressure-limit valve main body is provided with outside thread.
2. a kind of diesel engine oil duct pressure limiting structure according to claim 1, is characterized in that: the outer side wall of described pressure-limit valve main body lower end is positive six prism structures.
