Abstract
The utility model provides a regulating pressure type pressure-limiting valve, which is suitable for a pressure cooker, comprising a valve body, a valve cap, a valve seat, a valve core, a spring and a limiting pin. The regulating pressure type pressure-limiting valve is characterized in that the valves cap capable of regulating a pressure-limiting value is arranged on the upper part of the valve body, and the valve seat is fixed on the lower part of the valve body. The valve core is arranged in a cavity of the valve body, and the upper part of the valve core is fixedly connected with the valve cap. The valve body and the valve cap are capable of rotating mutually, and the limiting pin is arranged between the valve cap and the valve body. The utility model is used more safely by rotating the valve cap to control the pressure-limiting value. The utility model has the advantages of simple structure, safety and practicability. When users cook different foods, the pressure-limiting value of the pressure cooker is regulated, and the utility model is used more safely.
Description
Technical field
The utility model relates to a kind of pressure-adjusting type pressure limiting valve that is used for pressure cooker.
Background technology
The pressure limiting valve kind of using on the pressure cooker is a lot of at present, its form structure etc. also respectively has characteristics, but still there are some not really perfect places, adopt single pressure spacing such as general on the ground structure, but adopt the fixed pressure temperature to cook for different food, do not reach the science cooking methods that adopts the different pressures temperature at different foods, the voltage limiting value of its pressure limiting valve is fixed, can not regulate, in the use some inconvenience.Adopt metal material such as general pressure limiting valve again, the heat transfer of metal material is fast more, and the position of steam vent also be provided with science not, easily scald one's hand in the use.
The utility model content
The purpose of this utility model provides a kind of pressure-adjusting type pressure limiting valve that is applicable to pressure cooker.Adjust voltage limiting value by the rotation bonnet, use safer.
The utility model is achieved in that the pressure-adjusting type pressure limiting valve that a kind of pressure cooker cooker is used, comprise valve body, bonnet, valve seat, spool, spring and spacer pin, it is characterized in that the described bonnet of regulating voltage limiting value is arranged at the top of valve body, valve seat is fastenedly connected the bottom in valve body, spool is arranged in the cavity of valve body, and spool top and bonnet are connected.
Can rotate mutually between described valve body and the bonnet, be provided with spacer pin between bonnet and the valve body.
Described spool is provided with valve core housing outward, and valve core housing and valve body are connected, and the bottom is that the spool of taper can slide up and down in valve core housing, and the bottom of valve core housing also is taper, and the valve core housing top is provided with spring, and spring housing is located at the spool outside.
Described bonnet and valve body adopt high-temperature resistance plastice to make, and valve seat adopts metal material to make.
The utility model is simple in structure, and is safe and practical.Can when the different food of culinary art, regulate the voltage limiting value of pressure cooker, safety more convenient to use.

The specific embodiment
As shown in the figure, the utility model comprises valve body 8, bonnet 2, valve seat 10, spool 6, spring 3 and spacer pin 1, the described bonnet 2 of regulating voltage limiting value is arranged at the top of valve body 8, valve seat 10 is fastenedly connected in the bottom of valve body 8, spool 6 is arranged in the cavity of valve body 8, and spool 6 tops and bonnet 2 are connected.
Can rotate mutually between described valve body 8 and the bonnet 2, be provided with spacer pin 1 between bonnet 2 and the valve body 8.
The described spool 6 outer valve core housings 5 that are provided with, valve core housing 5 is connected with valve body 8, and the bottom is that the spool 6 of taper can slide up and down in valve core housing 5, and the bottom of valve core housing 5 also is taper, and valve core housing 5 tops are provided with spring 3, and spring 3 is sheathed on spool 6 outsides.
This pressure-adjusting type pressure limiting valve has two pressure limiting positions, i.e. high pressure and low pressure, and finish by rotating bonnet 2 two positions, is provided with spacer pin 1 between bonnet 2 and the valve body 8.In use, this pressure limiting valve is placed on the blast pipe 11 of pressure cooker lid.When the pressure of needs is higher, thereby the cone of spool 6 bottoms contacts sealed pressure-limiting (as shown in Figure 2) with the upper port of blast pipe sealing ring 13.When the pressure of needs hangs down, rotate bonnet 2 to spacer pin 1 and upspring, thereby the cone of valve core housing 5 bottoms contacts sealed pressure-limiting (as shown in Figure 3) with the lower port of blast pipe sealing ring 13.During work, the Pneumatic pipe cleaner in the pressure cooker is crossed blast pipe pressure is passed to spool, and when pressure reached certain value, spool and blast pipe sealing surface broke away from, and blast pipe begins exhaust.Owing to do not have steam vent on the valve body, the direction of its exhaust is from inside to outside, discharges from the gap between valve body and the blast pipe downwards, and then limits the pressure in the cooker, has also guaranteed safe in utilization simultaneously.
Described bonnet 2 and valve body 8 adopt high-temperature resistance plastice to make, and valve seat 10 adopts metal material to make.Just can not scald hand so in use, can satisfy the requirement of pressure limiting valve simultaneously yet weight.
