Description
Technical field
The present invention relates to a kind of rubber raw materials, specifically a kind of valve buffer liner.
Background technique
Water hammer refers in pipeline liquid injecting device system（Including pump）It is interior, biggish pressure is caused due to fluid flow change dramatically
The phenomenon that fluctuating and causing vibration.Also known as " water attack ".Its instantaneous pressure can substantially exceed normal pressure, and often generate destructive
It influences.
Influence of the water hammer to valve is even more very huge, and water hammer easily makes valve generate vibration, and high-intensitive vibration can break meeting
Can the sealing element of valve even results in the broken of valve, slacken rushing for water hammer by addition buffering inside on the inside of valve again
It hits.
