Description
Technical field:
The utility model relates to a kind of pressure cooker safety valve, belongs to the pressure cooker technical field.
Background technology:
In the prior art, pressure cooker is blasted in order to prevent that steam vent is blocked, and a safety valve will be installed on pressure cooker lid usually, and existing safety valve ubiquity that relief hole is too small, security is not high, dismounting trouble, problem such as not easy to clean.
Summary of the invention:
The purpose of this utility model is: provide a kind of high safety, the simple pressure cooker safety valve of dismounting, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises pressure cooker lid (1), on pot cover (1), be provided with pot cover relief hole (2), be provided with valve body (3) in pot cover relief hole (2) top, in valve body (3), be provided with rubber cushion (9), pressure limiting valve block (4) and pressure limiting spring (5) are installed on rubber cushion (9), on pressure limiting valve block (4), be provided with steam vent (6), on pressure limiting spring (5), be provided with pressure limiting spring cup (7), be provided with valve body relief hole (8) in the side of valve body (3); The aperture of pot cover relief hole (2) is 40mm; Adopt between valve body (3) and the pressure limiting spring cup (7) and be threaded.
The utility model adopts the structure that the valve body relief hole is set in safety valve valve body side, and is simple in structure, easy accessibility, and the aperture of the pot cover relief hole on the pot cover can be made into the size of 40mm, is difficult for stopping up the security that has improved safety valve greatly.Therefore compare with prior art, the utlity model has high safety, simple in structure, unpick and wash advantages such as convenient, not only can be used for the manufacturing of new pressure cooker, also can on existing pressure cooker lid, transform, reach good result of use.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: on pot cover (1), open a pot cover relief hole (2), in pot cover relief hole (2) top a valve body (3) is installed, in valve body (3), place a rubber cushion (9), go up at rubber cushion (9) then pressure limiting valve block (4) and pressure limiting spring (5) are installed, on pressure limiting valve block (4), have a steam vent (6), go up with pressure limiting spring cup (7) pressure limiting spring (5) is fixing at pressure limiting spring (5), adopt between valve body (3) and the pressure limiting spring cup (7) and be threaded, leave valve body relief hole (8) in the side of valve body (3), in order to prevent to stop up, the aperture of pot cover relief hole (2) is made into 40mm.
When the utility model used, when steam vent (6) was unobstructed, the gas of the pressure that overfulfils the quota was discharged by steam vent (6), the pressure cooker operate as normal.When steam vent (6) stops up, normally during pressure release, pressure limiting valve block (4) will overcome the pressure of pressure limiting spring (5) and opens under the effect of air pressure, gas is discharged from the valve body relief hole (8) on safety valve valve body (3) next door, has ensured the safe handling of pressure cooker.Adopt between valve body (3) and the pressure limiting spring cup (7) to be threaded, can regulate the pressure size of pressure limiting spring (5), make unpicking and washing of valve body (3) convenient simultaneously.
