Technical Field
The utility model relates to the field of safety valves, in particular to a low-temperature spring type safety valve of a bullet train.
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 low-temperature safety valve is one of safety valves, and the traditional bullet train low-temperature safety valve is too complex in structure, so that the manufacturing cost is too high, and the popularization is difficult.

The technical scheme of the utility model is realized as follows:
the low-temperature spring type safety valve for the bullet train comprises a valve body, wherein a valve cover is arranged at the top of the valve body, the bottom of the valve body is connected with a valve seat through a connecting portion, a spring is arranged in the valve body, a spring seat is arranged at the bottom of the spring, a valve clack is arranged at the bottom of the spring seat, and the valve clack is connected with the connecting portion through a connecting portion.
Preferably, the valve body is of a cylindrical structure with two open ends.
Preferably, a sealing gasket is arranged between the valve flap and the connecting part, and a limiting gasket is arranged between the connecting part and the connecting part.
Preferably, the bottom of the valve cover is provided with an adjusting bolt which is of an inverted convex structure.
Preferably, a pull rope is arranged on the top of the valve cover.
Preferably, the valve cover is in threaded fit connection with the valve body.
Preferably, the valve seat, the valve body, the valve cover, the valve flap, the spring, the adjusting bolt, the connecting portion and the connecting portion are all made of stainless steel.
By adopting the technical scheme, the utility model has the beneficial effects that:
the utility model is beautiful, simple, practical and exquisite in structure, light and compact in structure and higher in sensitivity, and meanwhile, the whole device is made of stainless steel, so that the device is superior in quality, the service life of the device is greatly prolonged, and the safety factor is higher.
