Abstract
The utility model relates to a hard-seal three-way ball valve, which includes a valve body, a valve cover, valve seats, a ball body, a valve rod, a handle, a seal piece and an installation pipe. Orthogonal cross channels are manufactured in the valve body, two pairs of valve seats are installed in the channels, and a T-shaped channel is manufactured in the ball body; the ball valve is mainly characterized in that the valve seats adopt floating structures and are in metallic seal fit with the ball body; a position adjusting mechanism is arranged on the handle, and comprises a positioning steel ball, a positioning spring, a steel ball positioning pin; the steel ball positioning pin is fixedly installed on the handle by a nut; the positioning steel ball is pressed and embedded in semi-spherical surface grooves in the upper plane of a packing gland; and the four semi-spherical surface grooves are evenly arranged in positions corresponding to ball valve opening and closing positions in the upper plane of the packing gland, so that the handle can rotate within 360 degrees, and the position of the handle can be determined according to the installation field requirements. The hard-seal three-way ball valve has the advantages of high applicable temperature, good wear-resisting property, convenience in installation and the like, and is suitable for a pulverized coal medium delivery pipeline in a power station.
Description
Technical field
The utility model relates to valve field, specifically about a kind of tee ball valve.The utility model is applicable to pulverized coal in power plant medium transport pipeline.
Background technique
Tee ball valve generally comprises valve body, valve gap, valve seat, spheroid, valve rod, Sealing and assembling set, is shaped on T shape passage in the valve body, and on passage two pairs of valve seats is installed, and is shaped on the corresponding T shape of valve body passage in the spheroid, realizes the switching to the medium transport passage.But existing tee ball valve is a fixed valve base, and soft seal cooperates between valve seat and the spheroid, and wear-resisting property is poor, and Applicable temperature is low, can not be used for the conveying operating mode of high temperature and abrasiveness medium.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of Applicable temperature height, hard sealing tee ball valve that wear-resisting property is good, easy for installation are provided.
The technical solution of the utility model comprises valve body, valve gap, valve seat, spheroid, valve rod, handle, Sealing and assembling set, is shaped on orthogonal cross passage in the valve body, and two pairs of valve seats are installed in passage, is shaped on T shape passage in the spheroid; Mainly be that valve seat is a floating structure, metallic seal cooperates between valve seat and the spheroid; Handle is provided with position adjusting mechanism, this position adjusting mechanism is made up of locking ball, retaining spring and steel ball locating stud, the steel ball locating stud is fixedly mounted on the handle by nut, locking ball is pressed by retaining spring and is embedded on the Gland in the hemisphere face groove in the plane, corresponding ball valve opens and closes the position in the plane on Gland, and four hemisphere face grooves evenly are set.
The utility model has the advantages that valve seat is a floating structure, metallic seal cooperates between valve seat and the spheroid, is provided with position adjusting mechanism on handle, makes 360 ° of rotations of handle, can determine handle position according to the needs of erecting bed, its Applicable temperature height, wear-resisting property are good, easy for installation.
