Description

Blowout prevention safety valve of oil pumping unit well head

Technical Field

The utility model relates to a relief valve technical field specifically is a relief valve is prevented spouting by beam-pumping unit well head.

Background

The safety valve is a special valve, wherein the opening and closing part is in a normally closed state under the action of external force, and when the pressure of a medium in equipment or a pipeline rises to exceed a specified value, the medium is discharged to the outside of the system to prevent the pressure of the medium in the pipeline or the equipment from exceeding the specified value. The safety valve is mainly used for boiler, pressure container and pipeline, and its control pressure is not greater than specified value, so that it can play important role in protecting personal safety and equipment operation. The injection and safety valve must be pressure tested before it can be used. The safety valve is a special branch of a valve family, and the particularity of the safety valve is that the safety valve only plays a role of opening and closing unlike other valves, and more importantly plays a role of protecting equipment. With the rapid development of economic construction in China, more and more equipment project projects with pressure control are provided. Safety valves play a crucial role in protecting equipment in view of the need to vent the equipment.

The safety valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve is opened to discharge a part of gas/fluid in the system to the outside of the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, and the system is ensured not to have accidents due to overhigh pressure. The safety valve is automatically opened and closed according to the working pressure of a pressure system, and is generally arranged on equipment or a pipeline of a closed system to protect the safety of the system. When the pressure or the temperature in the equipment or the pipeline exceeds the set pressure of the safety valve, the pressure relief or the temperature reduction is automatically started, the medium pressure in the equipment and the pipeline is ensured to be below the set pressure, the equipment and the pipeline are protected to normally work, accidents are prevented, and the loss is reduced.

The safety valve for the existing oil pumping machine can cause the leakage of the safety valve and the splashing of oil due to overlarge oil pressure.
