Description
Technical Field
The utility model relates to the technical field of petroleum machinery, in particular to novel metal floating seal superhigh pressure relief valve.
Background
The safety valve is a starting and closing part, is mainly used in an oil (gas) production wellhead device in oil drilling and production equipment, is in a normally closed state under the condition of free no hydraulic pressure, and is in a completely opened state under the action of hydraulic pressure in normal work. When the medium pressure in the channel rises to exceed the specified value, the channel needs to be cut off by the pressure relief of the safety valve actuator, so that the safety valve is completely closed, and the important protection effect is played on personal safety and equipment operation. The existing safety valve has the problems of poor sealing property and poor safety in the using process, and the using requirement cannot be met.
