Description
Technical field
The present invention relates to check-valves technical field, specifically a kind of Novel air valve type check-valves.
Background technique
Check-valves refers to opening and closing flap by own wt and spring force and pressure medium generation movement to block medium to flow backwards
A kind of valve.It is divided into lift and swing type by flap motion mode.When inlet pressure is greater than flap weight and its flowing resistance
When the sum of power, valve is turned on.Conversely, valve is then closed when medium is flow backwards.The disadvantage is that resistance is big, leakproofness is poor when closing.Mesh
Preceding valve check valve structure on the market is various, is broadly divided into two kinds: clock-type check-valves and Wafer Check Valves；Clock-type is stopped
Valve is returned due to advantage spatially, the pressure loss is very low, but due to clock body structure, figure is bigger than normal, and the point of seal leakage is just more
Some, the occasion for being suitble to some pairs of pressure loss requirements stringenter；The advantages of Wafer Check Valves be it is compact-sized, it is economical resistance to
With the installation direction of two kinds of check-valves is unrestricted, this is also a big advantage.
But the check-valves of existing market also has following defect: the gasket seal majority factory between air-valve assembly and valve body
Family's design is common metal annular gasket, and material majority is that red copper and 10# steel need to have the seal request height of plane
Good roughness, and excessive pretightning force is needed to guarantee, most check-valves has different degrees of leakage phenomenon；Most factories
The abradant surface that is sealed into of family's design valve seat and valve deck seals, and manufacture requirement is very high, and majority has leakage phenomenon；Most
Check-valves producer does not have the designed capacity of air valve, and the valve check-valves pressure loss of production is high, and negotiability is poor, uses
Service life is lower.Therefore, those skilled in the art provide a kind of Novel air valve type check-valves, to solve to mention in above-mentioned background technique
Out the problem of.
