Abstract
The utility model relates to a dedicated ball valve for refining sugar, which comprises a valve body, a valve seat, a ball, a valve rod, a bracket and a transmission mechanism, wherein the ball is mounted by a V-shaped structure; the spherical radian of the ball is 1/4 of the ball surface; the valve seat is a single valve seat and mounted in an inlet channel of the valve body; the internal diameter of an outlet flow channel of the valve body is larger than that of an inlet flow channel; and when the ball is opened, a flow channel communicated with an outlet channel of the valve body is formed between the outer circle sealing surface and the inner wall of the valve cavity. The dedicated ball valve can prevent stacking of medium impurities in the valve cavity, reduce abrasion of the sealing surface, and has the advantages of good sealing performance and long service life. The dedicated ball valve is a control valve suitable for the process pipeline in the sugar refining field.
Description
Technical field
The utility model relates to valve field, particularly about a kind of ball valve.The utility model is applicable to the control valve of sugar refining technology pipeline.
Background technique
The characteristics such as ball valve is simple in structure because of it, open-close convenient, flow resistance are little are widely used on the production technology pipeline of every profession and trade, and its structure generally is comprised of valve body, valve seat, spheroid, valve rod, and spheroid has the whole world and two kinds of structures of hemisphere.But in the manufacturing process of sugar manufacturing industry, medium contains particle and bar, and particle and bar in the existing ball-valve structure medium are piled up in valve pocket easily, causes that sealing surface damages, and affects sealability and working life.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, and the sugaring ball-valve dedicated of a kind of good seal performance and long service life is provided.
The technical solution of the utility model comprises valve body, valve seat, spheroid, valve rod, support, driving mechanism, spheroid adopts V-structure, the sphere radian that mainly is spheroid is 1/4 sphere, valve seat is single valve seat, be installed in the valve body inlet passage, valve outlet runner internal diameter when the type spheroid is opened, forms the runner with the valve outlet channel connection greater than the inlet channel internal diameter between its cylindrical sealing surface and the valve pocket inwall.
In above technological scheme, the ball seal face outside is shaped with annular scraper, and this scraper is formed by the Hardmetal materials built-up welding.
In above technological scheme, the eccentric installation between valve rod center line and the valve channel axis.
The utility model has the advantages that spheroid and valve seat adopt the import single-side sealing, body cavity and outlet passage formation runner prevent that the medium foreign material from piling up in valve pocket, reduce the wearing and tearing of sealing surface, good seal performance, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Sugaring ball-valve dedicated as shown in Figure 1, comprise valve body 4, valve seat 5, spheroid 6, valve rod 3, support 2, driving mechanism 1, spheroid 6 adopts V-structure, the sphere radian of spheroid 6 is 1/4 sphere, valve seat 5 is single valve seat, be installed in valve body 4 inlet passages, valve body 4 outlet flow internal diameters are greater than the inlet channel internal diameter, when spheroid 6 is opened, form the runner that is communicated with valve body 4 outlet passages between its cylindrical sealing surface and the valve pocket inwall, the interior medium foreign material of valve pocket are directly exported from valve body 4 release, prevent that the medium foreign material from piling up in valve pocket, reduce medium to the wearing and tearing of sealing surface, improve sealability, prolong product working life.
The spheroid 6 sealing surfaces outside is shaped with annular scraper 7, and this scraper 7 is formed by the Hardmetal materials built-up welding, scrapes off the foreign material on valve seat 5 sealing surfaces in closing process, reduces the wearing and tearing of sealing surface.
The eccentric installation reduces the wearing and tearing between the sealing surface between valve rod 3 center lines and valve body 4 passage axis.
