Abstract
The utility model discloses a check valve plate of a filter. The check valve plate comprises a round table-shaped sheet body, wherein a step hole is formed in the center of the sheet body; a wear resistant layer is coated on the inner wall of the step hole; an integral trumpet-shaped ring wing is arranged on the middle part of the annular wall of the sheet body; and an annular bump is arranged on the annular outer edge part of the ring wing. The check valve plate is simple in structure and reasonable in design, and the manufacture process is simple and convenient; the wear resistant layer plays a role of protecting the step hole of the sheet body; the service life of the check valve plate is prolonged; and the using requirement of an enterprise is met.
Description
Technical field:
The utility model relates generally to the filter cleaner technical field, relates in particular to a kind of filter cleaner non-return valve block.
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 made up of the filter component of one or several clean air.It mainly acts on is that filtering will get into 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 upper reaches are oil pump, and downstream are to need each lubricated component 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 to remove solid sundries such as being contained in iron oxide in the fuel oil, dust, 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 filter cleaner is used the non-return valve block.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of filter cleaner rational in infrastructure to use the non-return valve block.
The utility model is realized through following technological scheme:
A kind of filter cleaner non-return valve block includes the lamellar body of frustoconic shape, and it is characterized in that: said lamellar body center has step hole, scribbles scuff-resistant coating on the inwall of said step hole; Said lamellar body ring wall middle part is provided with the trumpet-shaped ring wing of being of one, and the position, annular outer of the said ring wing is provided with the projection of annular.
A kind of filter cleaner non-return valve block is characterized in that: said lamellar body ring wall bottom is provided with ring-shaped step.
A kind of filter cleaner non-return valve block is characterized in that: said lamellar body ring wall top is made as annular conical surface.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, and preparation process is simple and convenient, and the effect of protection lamellar body step hole is played in the design of scuff-resistant coating, prolonged this use novel working life, satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to accompanying drawing.
A kind of filter cleaner non-return valve block includes the lamellar body 1 of frustoconic shape, and lamellar body 1 center has step hole 2, scribbles scuff-resistant coating 3 on the inwall of said step hole 2; Said lamellar body 1 ring wall middle part is provided with the trumpet-shaped ring wing 4 of being of one, and the position, annular outer of the said ring wing 4 is provided with the projection 5 of annular.
