Abstract
The utility model discloses a check valve used for a water inlet of a filter. The check valve used for the water inlet of the filter comprises a conical piece body, the center of the piece body is opened with a stepped hole, and the inner wall of the stepped hole is coated with an anti-scratch layer; the middle of a surrounding wall of the piece body is provided with an integral horn shaped ring wing, a ring convex is arranged on an inner wall portion where an upper portion and a lower portion of the stepped hole crosses. The check valve used for the water inlet of the filter has the advantages of being simple in structure, reasonable in design, simple and convenient in manufacturing process, and the design of anti-scratch layer plays a role of protecting the stepped hole of the piece body and prolongs the service life of the check valve used for the water inlet of the filter, and the convex enables the check valve used for the water inlet of the filter to have a good tightness when cooperating with other products and the using demand of enterprises 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 water intake 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 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 filter cleaner water intake non-return valve block.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of check-valve for filter sheet rational in infrastructure to be provided.
The utility model is achieved through the following technical solutions:
A kind of filter cleaner water intake non-return valve block includes the lamellar body of frustoconic shape, and it is characterized in that: described lamellar body center has step hole, scribbles scuff-resistant coating on the inwall of described step hole; Described lamellar body ring wall middle part is provided with the trumpet-shaped ring wing of being of one, and the inwall position of the top of described step hole, bottom handing-over is provided with annular protrusion.
Described a kind of filter cleaner water intake non-return valve block is characterized in that: described lamellar body ring wall bottom is provided with ring-shaped step.
Described a kind of filter cleaner water intake non-return valve block is characterized in that: described 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; reasonable in design; preparation process is simple and convenient; the effect of protection lamellar body step hole is played in the design of scuff-resistant coating; prolonged this use novel working life; projection has satisfied the user demand of enterprise so that the utility model has good sealing when cooperating with other products.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to accompanying drawing.
A kind of filter cleaner water intake 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 described step hole 2; Described lamellar body 1 ring wall middle part is provided with the trumpet-shaped ring wing 4 of being of one, and the inwall position of the top of step hole, bottom handing-over is provided with annular protrusion 5.
