Introduction to gas ball valve: gas ball valve is a valve that uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action
It is suitable for regular operation, and it can be opened and closed quickly and easily
Low fluid resistance
The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance
The sealing performance is not affected by the installation direction, and the flow direction of the medium can be arbitrary
No vibration, low noise

Special gas ball valve features: suitable for regular operation, quick and light opening and closing
Low fluid resistance
The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance
The sealing performance is not affected by the installation direction, The flow direction of media can be arbitrary
No vibration, low noise

1、 Scope of use: the ball valve is mainly used to cut off, distribute and change the direction of medium flow on the pipeline
In order to prolong the service life of the ball valve, it should be fully Kai and fully closed

2、 Main technical parameters of the product: 1
Copper material is selected and hot forging process is adopted 2
The working medium of ball valve is Shui, oil, gas, etc
3
Working temperature -10 ℃ ≤ t≤ 120℃。 4
The nominal pressure is 2
5MPa, 2
0MPa and 1
6Mpa respectively

3、 Ball valve installation guide:
1
When installing and tightening the ball valve connected by pipe thread, the pipe should be vertical to the end face of the valve body, and the hexagonal or octagonal part of the same side end of the thread should not be wrenched at the hexagonal or octagonal or other parts of the other end, so as not to cause deformation of the valve body or affect Kai startup

2
When connecting the ball valve with internal thread, the length of the external thread at the pipe end must be controlled to prevent the pipe end thread from being too long
When screwing in, the internal thread end face of the ball valve is pressed, causing the valve body to deform and affecting the sealing performance

3
When the ball valve connected by pipe thread is connected with the thread at the pipe end, the internal thread can be conical pipe thread or cylindrical pipe thread, but the external thread must be conical pipe thread, otherwise it will lead to loose connection and leakage

4
The Shang graduation circle of flange ball valve shall be consistent with the Fen graduation circle on the pipe flange before matching
The center of the pipeline at both ends shall be perpendicular to the flange surface of the flange ball valve, otherwise the valve body will be distorted and deformed

5
When installing the ball valve with pipe thread connection, the sealing material should be clean

6
During installation, pay attention that there should be no obstacles within the opening and closing range of the ball valve handle, such as walls, pipes, connecting nuts, etc

7
When the handle of the ball valve is parallel to the direction of the valve body, it is Kai, and when it is vertical, it is off

8
The medium should be free of particles, corrosive gases or liquids
