What is the effect of Surface Safety Valve？

Ground safety valve is a ground safety system to ensure the safe exploitation and transportation of oil and gas. Ground safety valves (hydraulic safety valve and pneumatic safety valve) are used for safety protection of well site in oil and gas leakage, fire and other emergency situations. Safety valve is normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises beyond the specified value, the medium pressure in the pipeline or equipment can be prevented from exceeding the specified value by discharging the medium to the outside of the system.
