Description
Technical field
The present invention relates to a kind of pressure limiting valve, particularly a kind of spring many grades of pressure-adjustable pressure limiting valves for cooking equipment.
Background technology
Pressure cooker be a kind of pressure that utilizes to improve the device of cooking temp, a kind of is pressure cooker for open firing, and a kind of is the electric pressure cooking saucepan utilizing electric energy to heat.With it can by by the heat foods of boiling to more than 100 DEG C.It, with the HTHP function of uniqueness, substantially reduces the time of cooking, and has saved the energy.But existing pressure cooker pressure limiting valve used is the pressure limiting valve of a fixed weight, be only a kind of pressure when the weight of pressure valve determines pressure cooker work, and for different food, its pressure needed for culinary art is also different.Single pressure is unfavorable for cooking multiple different food, and this pursues healthy cooking culture to China and does not conform to.
For electric pressure cooking saucepan, realize many grades of pressure regulation, existing disclosed patent has to be increased multiple pressure switch to realize on elasticity outer pot, which increases cost; The relationship change of with good grounds temperature and pressure carrys out controlled pressure, and this technology, once automatically controlled inefficacy, can cause potential safety hazard.And this technology adopts the decrement that relies on and change spring thus produces different elastic force and act on spool to realize pressure adjustable, there is higher security.
Existing safety device for pressure cooker structure is varied, such as publication number is the Chinese patent of CN2281734, it discloses a kind of high-pressure cooker pressure limiting valve, in pot cover, spool is installed, the bottom of spool connects exhaust nut, suitable for reading and the main pressure limiting valve mates of the steam vent of spool, main balancing weight is had in main pressure limiting valve body, secondary pressure limiting valve body is had below main pressure limiting valve body, in secondary pressure limiting valve body, secondary balancing weight is installed, secondary pressure limiting valve body there is drag hook, ear is had in main pressure limiting valve body, ear matches with drag hook, pressure limiting valve seat is installed under pressure limiting valve body, boss is had in pressure limiting valve seat, pressure limiting valve seat boss matches with the tenon of main pressure limiting body base.Above-mentioned high-pressure cooker pressure limiting valve is uncontrollable to the pressure in pot, so easily that food is well-done in the process used, thus affects mouthfeel, even damages nutrition.
Certainly the pressure limiting valve of adjustable pot inner pressure is also had at present, such as publication number is the Chinese patent of CN2201088465, it discloses a kind of many classification pressure limiting valve for pressure cookers of convenient cleaning, it is by the valve seat connecting pot cover, be connected to the valve body on valve seat, be connected to the pressure limiting knob on valve body, be placed in the steel ball on valve seat, be located at the bearing plate on steel ball, be connected to the spring between bearing plate and adjusting pressuring knob, be enclosed within the O type circle on inner core, the blast pipe inserted in valve body openings is formed, valve outer wall is provided with two symmetrical oblique guiding troughs, two plush coppers of pressure limiting knob bottom match with oblique guiding trough.Although this pressure limiting valve can regulate the pressure in pot, there are some problems, such as steel ball inherently has weight, can not realize being vented completely, have potential safety hazard; And for example two plush coppers of pressure limiting knob bottom are unstable when oblique guiding trough slides, pot will inevitably produce earthquake motion in various degree when in use, two plush coppers of pressure limiting knob bottom will certainly be caused to be moved at oblique guiding trough, thus the maximum pressure more become in pot, and adopt the mode of this electrodeless adjustment to be also not easy to be adjusted to suitable pressure, will inevitably make troubles to user.
