The sphere of the stainless steel standard ball valve is floating. Under the action of the dielectric pressure, the sphere can produce the displacement of the body and press it on the sealing surface of the exit end to ensure that the seal of the exit end is sealed. So you know the stainless steel beauty standard ball valve operation and use methods?
Operation and use of stainless steel standard ball valve are as follows:
1. Ensure that the line and valve have been washed before operation.
2. The valve rotates the valve rod according to the actuator input signal: the valve is closed by 1 / 4 turn (90). Open valve on 1 / 4 (90).
3. When the actuator direction indicates that the arrow is parallel to the pipeline, the valve is open; when the indicating arrow is vertical to the pipeline, the valve is closed.
4. All kinds of manual ball valves installed on the thermal insulation pipe shall not be handled down.
5. Installation position, height, import and exit direction shall meet the design requirements, and the connection should be firm and close.
The structure of the stainless steel American standard ball valve is simple, good sealing, but the load of the sphere under the working medium is all passed to the outlet sealing ring, so consider whether the sealing ring material can withstand the working load of the spherical medium, in the case of higher pressure impact, the sphere may be offset. This structure is generally used for medium and low pressure ball valves.
