Shineeast wellhead safety valve control system is an emergency shut-off system, which is designed, manufactured and tested according to the control panel, combined with practical working conditions. The system is used for the effective control of oil/gas well ground safety valve, subsurface safety valve and wing valve, achieving corresponding protective and explosive-proof grade, guaranteeing oil/gas well production safety, providing security protection for oil and gas wellhead of wild unattended environment.

Providing air driven liquid pump and hand pump, the system can automatically maintain pressure, fill pressure and keep hydraulic system operating with constant pressure; as wellhead is closed, hand pump will operate, and meantime the accumulator in the high-pressure pipeline can compensate pressure drawdown due to environment temperature dropping or safety valve leakage; and it can also control ground safety valve and subsurface safety valve simultaneously; the system is used for oil field manufacturing, oil mechanical equipment manufacturing and scientific research.

High-low sensor valve real-time monitoring wellhead pipeline pressure, the system can automatically close subsurface safety valve and ground safety valve to close down wellhead when the wellhead pressure is higher than the set high pressure value or lower than the set low pressure value.

When there is a fire on the wellhead, environment temperature rising rapidly to melting temperature of fusible plug, fusible plug melts and cuts off the system loop, to realize wellhead completely closed down.

With pressure automatically compensating and releasing functions, pneumatic pumps will automatically compensate system pressure to maintain the system working normally when the system pressure drops due to the environment temperature and pipeline leakage of ground safety valve and subsurface safety valve. The relief valve can automatically release excess pressure to maintain system normal pressure when the system pressure is higher than set value due to environment temperature or human misoperation.

 

Suitable for low and high temperature environment, the system components can work at - 30 to 60°C.

With remote emergency shut-off system, we can shut off the wellhead emergently through on-site manual operation, and can also shut off the wellhead through shutting off the subsurface and ground safety valve, no need site operation, when finding anomalies on wellhead on duty room.

Independent control of single well & single valve, single well & multivalve and multi-Well & multivalve can be realized;

Pressure piping adopts welding type pipeline connection, eliminating leakage, convenient maintenance.
