Abstract
The utility model discloses a check valve piece for a filter, which is characterized by comprising a ring-tapered piece body; the lower port part of the lower end of the piece body is horizontally contracted towards the inner side and is then bended downwards, so that a water inlet can be formed; the tapered inner wall of the piece body and the ring edge part at the upper part of the piece body are respectively provided with a ring-shaped bulge; and the inner wall of the piece body is provided with a wear-resistant layer. The check valve piece for the filter is simple in structure, reasonable in design as well as simple and convenient in manufacturing technology; and due to the design of the wear-resistant layer, the check valve piece can be prevented from being worn, the service life of the check valve piece is prolonged, and the use demands of enterprises can be met.
Description
Technical field:
The utility model relates generally to the filter cleaner technical field, relates in particular to a kind of filter cleaner and uses the 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 is used the non-return valve block, it is characterized in that: include the lamellar body of ring taper, lamellar body lower end oral area level to the inside shrinks back bending downwards and forms water intake, on the conical inboard wall of lamellar body and top loop be respectively equipped with the convexity of annular along the position.
A kind of filter cleaner is used the non-return valve block, it is characterized in that: the inwall of said lamellar body is provided with scuff-resistant coating.
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, can place the utility model through the design of scuff-resistant coating and be worn, and prolongs the working life of the utility model, 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 is used the non-return valve block, includes the lamellar body 1 of ring taper, and lamellar body 1 lower end oral area level to the inside shrinks back bending downwards and forms water intake 2, on the conical inboard wall of lamellar body 1 and top loop be respectively equipped with the convexity 3,4 of annular along the position.The inwall of lamellar body 1 is provided with scuff-resistant coating 5.
