Referring to shown in Fig. 1-2, a kind of ball valve, the hollow sphere 3 including valve body and in the valve body is described
Valve body both ends are equipped with the first valve seat 5, the second valve seat 4, flexible gasket 12 between the valve seat and valve body, the valve seat with
The sphere can connect to form sealing structure, the drive shaft 8 that the sphere connection is driven by Electric Actuator, Jie of the valve body
Matter approaching side installation resilient material makes the rectifying disc 6 to be formed, and the rectifying disc is equipped with multiple rectification holes 61.
The diameter of the rectification hole 61 can be designed as needed, specific unlimited.Preferably, the rectification
Hole 61 is round hole.
The rectifying disc 6 can be used to be made with certain elastic rubbery body, and when installation can be directly clamped among in the valve body,
It is interference fitted and connects with valve body, and the inside of corresponding elastic sealing gasket 12 is in contact.
It is stably connected with to realize, 6 medial surface of rectifying disc, i.e., passes through glue connection, installation with 5 contact surface of the first valve seat
When, after the first valve seat 5 is installed, then rectifying disc 6 is pressed by the gluing on the contact surface of the first valve seat 5, make rectifying disc with
First valve seat 5 is bonded, and can greatly enhance the connective stability of rectifying disc in this way, and with 12 inside of elastic sealing gasket of respective side
Mutually interference fit connection.
It should be noted that in the utility model, the first valve body of the installation in valve body and the second valve body with
Elastic sealing gasket 12 between valve body can be made with rubber material.
The utility model ball valve installs resilient material by the medium approaching side of valve body and makes the rectifying disc to be formed, institute
Rectifying disc is stated equipped with multiple rectification holes, can realize and rectification is carried out to the medium flowed through, eliminate the turbulent flow that flow of media generates
Phenomenon, it is ensured that the stability of the meteor monitoring of flowmeter below.
Wherein, the rectifying disc 6 is convex configuration, and the periphery of the rectifying disc has the inner wall for the valve body
The clamping ring 60 that face connects.
Wherein, there is Electric Actuator mounting platform 7 in the upper end of the valve body, has drive in the Electric Actuator mounting platform
Moving axis mounting hole, it is described driving shaft mounting hole and the drive shaft between circular sealing ring 9 is installed, including upper sealing ring,
