Description
The technical field is as follows:
the utility model relates to a petroleum safety valve.
Background art:
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 safety valve can be used only after pressure test, and 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 application of the petroleum safety valve greatly facilitates petroleum transportation control, but the existing petroleum safety valve has a plurality of defects: the service life is short, the flow control is inconvenient, and the pressure bearing degree can not be adjusted.
The utility model has the following contents:
the to-be-solved technical problem of the utility model is to provide an oil safety valve, the device have realized that the extension relief valve uses the mission, through the range of lift of control valve rod and valve plate to adjust flow, and controlled the pressurized ability of valve plate, accommodation process is simple and convenient. The defects that the service life of the existing petroleum safety valve is short, the flow control is inconvenient, and the pressure bearing degree cannot be adjusted are overcome.
The utility model adopts the technical proposal that: a petroleum safety valve comprises a valve body and a valve plate, wherein one end of the valve body is provided with an oil inlet, and the other end of the valve body is provided with an oil outlet; the valve body top is installed the lamina tecti, fixed plate and limit baffle are installed to the lamina tecti bottom, set up the floating plate between fixed plate and the limit baffle, install the second spring between fixed plate and the floating plate, install the valve rod between floating plate and the limit baffle, the valve plate is connected to the valve rod bottom, the lamina tecti upper end sets up protective barrel, the valve rod top is connected with the holding down plate in the protective barrel, the holding down plate upper end is connected through first spring coupling, the telescopic link is connected to the holding down plate upper end, telescopic link upper end installation air pressure device, air pressure device is connected with control panel, air pressure device can control the telescopic link and stretch out and draw back.
The control panel is arranged on the outer side of the upper end of the protective cylinder.
The utility model has the advantages that: the utility model discloses an extension relief valve uses the mission, through the range of lift of control valve rod and valve plate to adjust the flow, and controlled the pressurized ability of valve plate, accommodation process is simple and convenient.
Description of the drawings:
the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
