Abstract
The utility model discloses a valve core structure applied to an air filtering and cleaning device. The valve core structure applied to an air filtering and cleaning device comprises a valve rod and is characterized in that an end of the valve rod is provided with a plugging head, a front end face of the plugging head is a spherical face which is provided with a protruding outer side and a concaved inner side, annular grooves are distributed at an outer side wall of the plugging head, sealing rings are mounted in the annular grooves in a matching manner, the valve rod is provided with an inverted taper-shaped retaining block arranged at a rear end of the plugging head, the inverted taper-shaped retaining block is provided with a retaining face which matches with a water outlet hole in a retaining manner, and the gap between the plugging head and the inverted taper-shaped retaining block which are spaced apart is an arc insertion matching section. The valve core structure applied to an air filtering and cleaning device in the utility model is characterized by reasonable structure design, convenience of use, good sealing performance, excellent wear-resistant performance realized through a wear resistant layer arranged at the outer side wall of the plugging head, and prolonged service life.
Description
Technical field
The utility model relates to the filter cleaner technical field, relates in particular to a kind of valve core structure that is applied in the air-strainer.
Background technique
Filter cleaner includes air-strainer, oil filter and fuel filter.
Air-strainer is arranged in engine aspirating system, the assembly that it is comprised of the filter component of one or several clean air.Its Main Function is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.
Oil filter is arranged in engine lubrication system.Its upstream is oil pump, and the downstream is to need each component of lubricating in the motor.Its effect is to carrying out filtering from objectionable impurities in the machine oil of oil sump, with kinematic pair such as the engine oil supplying bent axle of cleaning, connecting rod, camshaft, pressurized machine, piston rings, plays lubricated, cooling, cleaning action, thereby prolongs the life-span of these component.
Fuel filter is on the pipeline that is connected between fuel pump and the throttle valve body filler opening.The effect of fuel filter is that solid sundries such as being contained in iron oxide in the fuel oil, dust is removed, and prevents that oil-fired system from stopping up.
The structure of each parts will have influence on the usability of filter cleaner in the filter cleaner.Such as water drain valve core for filter.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of valve core structure that is applied in the air-strainer to be provided, its reasonable in design, and easy to use, good seal performance has improved working life.
The utility model is achieved through the following technical solutions:
A kind of valve core structure that is applied in the air-strainer, include valve rod, it is characterized in that: described valve rod one end is provided with plug, the front-end face of described plug is the spherical of evagination indent, the outer wall of described plug has annular groove, cooperate in the described annular groove seal ring is installed, the valve rod of described plug rear end is provided with the inverted cone retreat stop block, described inverted cone retreat stop block is provided with the retaining face that cooperates with the dewatering orifice retaining, keeps at a certain distance away between described plug and the inverted cone retreat stop block to be arc inserting section.
The outer side wall of described plug is provided with wearing layer.
The major diameter size of described inverted cone retreat stop block is less than the excircle dimension of plug.
Its principle is: the front-end face of described plug is the spherical of evagination indent, the convenient cooperation, structural design by inverted cone retreat stop block and arc inserting section, the convenient use, by cooperating in the annular groove seal ring is installed, good seal performance, the wearing layer that the outer side wall by plug is provided with, wear-resisting property is good, has improved working life.
The utility model has the advantages that:
The utility model reasonable in design, the convenient use, good seal performance, the wearing layer that the outer side wall by plug is provided with, wear-resisting property is good, has improved working life.
Description of drawings
Fig. 1 is the utility model structure sectional view.
Embodiment
