Abstract
A hard sealing wear-resistant eccentric ball valve comprises a valve body (1), a valve seat (2), a valve cover (3) and an eccentric semi-spherical spool. The eccentric semi-spherical spool is composed of spool body (4) and a steel spool board (5), wherein the steel spool board (5) is installed on the eccentric semi-spherical spool. An anti-corrosion wear-resistant alloy layer is welded on the valve seat (2) at a position where the valve seat (2) contacts with the steel spool board (5). The hard sealing wear-resistant eccentric ball valve has the advantages of being good in wear-resistance, long in service life, good in seal performance and excellent in shearing due to the fact that the eccentric ball valve uses the steel spool board to realize hard seal instead of using a rubber seal layer to realize soft seal, simultaneously the anti-corrosion wear-resistant alloy layer is welded on the valve seat and the anti-corrosion wear-resistant alloy layer and the steel spool board both adopt the design of spherical structure.
Description
Technical field
The utility model relates to the Liquid valve field.Relate in particular to a kind of wear-resisting eccentric half-ball valve.
Background technique
Existing eccentric half-ball valve mainly is made of valve body, valve seat, eccentric semi-spherical spool, valve core rod and valve handle, and the eccentric semi-spherical spool is made of valve core and rubber sealant, and the whole sulfuration of rubber sealant is on the hemisphere of valve core.Its deficiency is: under the more media environment of impurity, its rubber sealant wear resistance is good inadequately, and fall short of working life, and it is poor to shear function.
The model utility content
The purpose of this utility model is exactly at the above-mentioned deficiency of existing eccentric half-ball valve, and provides a kind of hard sealing wear-resisting eccentric ball valve.
The utility model comprises valve body, valve seat, valve gap and eccentric semi-spherical spool, and the eccentric semi-spherical spool is made of valve core and rubber sealant, and rubber sealant is replaced by the steel valve core plate, and the steel valve core plate is installed on the eccentric semi-spherical spool.
Be welded with the alloy-layer of anticorrosion antiwear on the valve seat of valve seat and steel valve core plate contacting point, and the alloy-layer of anticorrosion antiwear and steel valve core plate all adopt the spheric structure design.
The material of the anticorrosion antiwear alloy-layer that is welded with on valve seat is different with the steel valve core plate.
The utility model has the advantages that: realize hard sealing owing to come soft seal to change into rubber sealant eccentric ball valve with the steel valve core plate, on valve seat, be welded with simultaneously the anticorrosion antiwear alloy-layer, and the alloy-layer of anticorrosion antiwear and steel valve core plate all adopt the spheric structure design, thereby wear resistance is good, long service life, good seal performance is sheared the foreign material in the medium easily.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises valve body 1, valve seat 2, valve gap 3 and eccentric semi-spherical spool, and the eccentric semi-spherical spool is made up of valve core 4 and steel valve core plate 5, and steel valve core plate 5 usefulness clamping bolts are installed on the eccentric semi-spherical spool.Be welded with the alloy-layer of anticorrosion antiwear on the valve seat 2 of valve seat 2 and steel valve core plate 5 contacting points, and the alloy-layer of anticorrosion antiwear all adopts spheric structure design with the steel valve core plate.The anticorrosion antiwear alloy-layer that is welded with on valve seat 2 is different with the alloy material of steel valve core plate 5.
Claims (3)
1. one kind seals wear-resisting eccentric ball valve firmly, it comprises valve body (1), valve seat (2), valve gap (3) and eccentric semi-spherical spool, the eccentric semi-spherical spool is made of valve core (4) and rubber sealant, it is characterized in that rubber sealant is replaced by steel valve core plate (5), steel valve core plate (5) is installed on the eccentric semi-spherical spool.
2. the wear-resisting eccentric ball valve of hard sealing according to claim 1, it is characterized in that being welded with on the valve seat (2) of valve seat (2) and steel valve core plate (5) contacting point the alloy-layer of anticorrosion antiwear, and the alloy-layer of anticorrosion antiwear all adopts spheric structure design with steel valve core plate (5).
3. the wear-resisting eccentric ball valve of hard sealing according to claim 1 is characterized in that the material of the anticorrosion antiwear alloy-layer that is welded with is different with the steel valve core plate on valve seat (2).
