There is angular sealing, the sphere is provided with circular through hole in the vertical direction, is equipped with flat slot, the sphere inside the circular through hole
Top is connected with upper valve rod, and the upper valve rod includes stem head, sealing clamp and flat falcon, and the stem head is endless track shape,
The sealing clamp is adapted with circular through hole, and the flat falcon is meshed with flat slot, is formed between the upper valve rod and valve body
It fills a vacancy and locates to be filled with filler, be threaded with lower valve rod below the sphere, pressing plate, institute are connected with below the lower valve rod
The internal whorl for stating pressing plate is connected with hex screw.
Preferably, bolt hole is equipped at the neck of the valve body.
Preferably, the filler is fluoroplastics material.
Preferably, it is sealed between the filler and upper valve rod by gland.
Preferably, the angular height for being sealed in sphere is not higher than height of the circular through hole on sphere.
Preferably, the upper valve rod and lower valve rod do axis rotation with the center line of sphere vertical direction.
The technical effect and advantage of the utility model: the fixing ball valve utilizes the engagement of flat falcon and flat slot, and utilizes sealing
Pressing plate is sealed, while the rotation of sphere is driven using the stem head of endless track shape, and there is enough intensity to drive
Sphere reduces the pressure of bearing, further alleviates the pressure of bearing come the active force of supporting sephere using angular sealing, keeps away
Exempt from bearing to frequently check and replace, it is very convenient.
