Technical Field
The utility model relates to the field of safety valves, in particular to a safety valve convenient for adjusting a pressure value.
Background
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 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 must be pressure tested before it can be used.
The existing safety valve needs to be adjusted by means of a tool when the pressure value is adjusted, and is very inconvenient to use, so that the safety valve convenient for adjusting the pressure value is needed to meet the market demand.

The technical scheme of the utility model is realized as follows:
the safety valve convenient for adjusting the pressure value comprises a valve body, wherein a valve seat is connected to the bottom of the valve body, an adjusting cavity is formed in the valve body, an adjusting bolt is arranged at the inner top of the adjusting cavity, a spring is installed at the bottom of the adjusting bolt, a valve core is arranged at the bottom of the spring, and the valve core is located between the valve body and the valve seat.
Preferably, the valve body and the valve seat are fixedly connected through a sealing connecting rod.
Preferably, a nut is arranged on the outer side of the valve body.
Preferably, the top of the adjusting bolt is provided with an adjusting rod, and the adjusting rod penetrates through the top of the valve body.
Preferably, a key ring is arranged at the top of the adjusting rod.
Preferably, the outer side of the valve body is sleeved with a plastic sleeve.
Preferably, a sealing gasket is arranged between the valve seat and the valve body.
