Abstract

The utility model provides a pressure cooker safety valve, comprising a valve body, a valve rod, a spring and a sealing ring. The valve rod is arranged in the valve body chamber made of thermo-stable plastic, and the spring and the sealing ring are sheathed at the outside of the valve rod. The utility model which has the advantages of simple structure and stable function can make sure the pressure in a kettle limited in certain scope and the safe use of a pressure cook ware. The valve body is made of thermo-stable plastic, and the coefficient of overall heat transmission is low, so that the scald of users when using the pressure container can be avoided, and simultaneously the cost is low, and the processing is easy.

Description

The pressure cooker safety valve
Technical field
The utility model relates to a kind of pressure cooker safety valve, mainly uses on pressure cooker and pressure vessel.
Background technology
Kind, specification, the shape of the safety valve of pressure cooker cooker use at present are a lot, use also very extensively.Though be more and more safer on function, but still some incomplete places arranged.Such as: in the selection of safety valve valve body material, adopt aluminium alloy or stainless steel and other metal materials usually, and cost height, difficulty of processing are big.Though these valves can reach the function of safe exhaust, in use, in use there is potential safety hazard because the accident that the consumer is scalded takes place the good heat conductivity of metal material easily.
The utility model content
The purpose of this utility model provides a kind of pressure cooker safety valve safe in utilization simple in structure.
The utility model is achieved in that a kind of pressure cooker safety valve, comprises valve body, valve rod, spring and sealing ring, it is characterized in that described valve rod is arranged at the body cavity of being made by high-temperature resistance plastice, and valve rod is with spring and sealing ring outward.
Described valve stem tip is a protruding cap, and protruding cap below is provided with a scrobicular ring, and sealing ring is set in the scrobicular ring; Described valve body upper end is provided with groove, and valve rod is packed into from the valve body top, and the protruding cap of valve rod places the groove of valve body, and spring is inserted in the valve rod lower end, and the spring lock-screw is housed.
The utility model is simple in structure, and function-stable can guarantee that pot inner pressure is limited in certain scope, guarantees that pressure cooker is safe in utilization.Valve body uses high-temperature resistance plastice to make, and its coefficient of overall heat transmission is low, can avoid the user to contact valve body when the working pressure container and is scalded, and production cost is low simultaneously, easily processing.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
1 valve body, 2 valve rods, 3 sealing rings, 4 springs, 5 lock-screws, 6 protruding caps, 7 scrobicular rings, 8 grooves
The specific embodiment
As shown in the figure, the utility model comprises valve body 1, valve rod 2, spring 4 and sealing ring 3, and described valve rod 2 is arranged at valve body 1 inner chamber of being made by high-temperature resistance plastice, valve rod 2 outer spring 4 and the sealing rings 3 of being with.Valve body 1 uses high-temperature resistance plastice to make, and its coefficient of overall heat transmission is low, and can avoid the user when the working pressure container, to contact valve body 1 and scalded,
Described valve rod 2 tops are a protruding cap 6, and protruding cap 6 belows are provided with a scrobicular ring 7, and sealing ring 3 is set in the scrobicular ring 7; Described valve body 1 upper end is provided with groove 8, and valve rod 2 is packed into from valve body 1 top, and the protruding cap 6 of valve rod 2 places groove 8 places of valve body, and spring 4 is inserted in valve rod 2 lower ends, and spring lock-screw 5 is housed.Valve rod 2 seals by silica gel sealing ring 3 with valve body 1, at nature lower valve rod and valve body is relative static, when pressure reaches certain value, valve rod 2 container inner pressures push away valve body 1, overcome spring force and rise, sealing ring 3 loses sealing function, the gap automatic vent of container inner pressure this moment between valve body 1 and valve rod 2, make container inner pressure can not continue again to raise, guarantee safe in utilization.

Claims (2)
