Abstract
The utility model relates to a kind of without abrasion ball check valve, including valve body, sphere, valve deck, sphere is hollow ball, valve body, which is imported and exported, is equipped with valve seat between channel, guide sleeve is installed between valve seat exit end face and valve deck, the guide sleeve is cylindrical structure, has a diameter larger than sphere diameter, guide sleeve circumference is formed with several discharge orifices；Mainly sphere is used in the coated rubber layer composition of metal hollow ball surface.Sphere and valve seat generate buffer function when closing, and reduce collision and the abrasion of sealing surface, and sealing performance is reliable.
Description
Technical field
The utility model belongs to valve field more particularly to a kind of ball check valve.
Background technique
Ball check valve is mounted on medium pipeline the valve for preventing medium from flowing backwards, and structure includes valve body, sphere, valve body
It imports and exports and is equipped with valve seat between channel, for sphere installation in the valve chamber of valve seat outlet side, import pressure medium pushes sphere to rise,
Medium is truncated with sphere weight collective effect in flow of media, reverse media, reaches pipeline one-way flow function.But it is existing
Ball check valve has the drawback that, when reverse media pushes sphere and valve seat is closed, sphere generates biggish touch with valve seat
It hits, so that the two sealing surface is generated abrasion, or even make hollow ball collision deformation, influence the sealing matching property of sphere and valve seat.
Summary of the invention
The utility model is directed to disadvantage of the existing technology, provides a kind of sphere and the prooving of valve seat is small, sealing reliability
It is good without abrasion ball check valve.
The technical solution of the utility model includes valve body, sphere, valve deck, and sphere is hollow ball, and valve body imports and exports channel
Between be equipped with valve seat, guide sleeve is installed between valve seat exit end face and valve deck, which is cylindrical structure, and diameter is big
In sphere diameter, guide sleeve circumference is formed with several discharge orifices；Mainly sphere is used in the coated rubber layer of metal hollow ball surface
Composition.
The utility model has the advantages that spherome surface has rubber layer, sphere and valve seat is made to generate buffer function when closing,
Reduce collision and the abrasion of sealing surface, sealing performance is reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is as shown in Figure 1 without abrasion ball check valve, including valve body 1, sphere 2, valve deck 4, sphere 2 is hollow ball, valve
Body 1, which is imported and exported, is equipped with valve seat between channel, guide sleeve 3 is installed between valve seat exit end face and valve deck 4, which is circle
Core structure has a diameter larger than 2 diameter of sphere, and sphere 2 is made to float up and down in 3 cylinder of guide sleeve, if 3 circumference of guide sleeve is formed with
Dry discharge orifice；Mainly sphere 2 produces sphere 2 when closing with valve seat using in the coated rubber layer composition of metal hollow ball surface
Raw buffer function, reduces collision and abrasion.
