Abstract
The utility model discloses a water drain valve core structure with an abrasion resistant layer. The water drain valve core structure with the abrasion resistant layer comprises a valve rod and is characterized in that a choke plug is arranged at one end of the valve rod, a front end face of the choke plug is a spherical surface, the abrasion resistant layer is mounted on the outer side wall of the choke plug, annular grooves are distributed on the outer side wall of the choke plug, sealing rings are installed in the annular grooves in a matching mode, an inverted cone backstop block is arranged on the valve rod at the rear end of the choke plug, and an annular concave cavity is mounted on the valve rod between the inverted cone backstop block and the choke plug. The water drain valve core structure with the abrasion resistant layer has the advantages that the structural design is reasonable, the usage is convenient, the sealing performance is good, the good abrasion resistance is achieved by the aid of the abrasion resistant layer on the outer side wall of the choke plug, and the service life is prolonged.
Description
Technical field
The utility model relates to the filter cleaner technical field, relates in particular to a kind of water drain valve core structure with wearing layer.
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 water drain valve core structure with wearing layer 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 band wearing layer water drain valve core structure, 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 spherical, the outer side wall of described plug is provided with wearing layer, and is distributed with annular groove, cooperates 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, and the valve rod between described inverted cone retaining and the plug is provided with annular cavity.
The major diameter size of described inverted cone retreat stop block is less than the excircle dimension of plug.
Its principle is: by the structural design of inverted cone retreat stop block and annular cavity, the convenient use is equipped with seal ring by cooperating in the annular groove, good seal performance, and 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.
