Abstract
A gland pressure cooker comprising a cooker body, a cooker cover, two cooker ears, a spring beam, a regulating apparatus, and a pressure-limiting valve. Wherein the spring beam is supported by two cooker ears, the regulating apparatus comprises a screw stem fixed on the cooker cover by a support rod, a screw gasket connected with the screw stem by screw, and a handle ganged with the screw gasket, and the regulating apparatus also includes a limiting element, the screw gasket comprises a upper screw gasket and a screw gasket fixed on the upper screw gasket, the screw stem is threaded connected with the lower screw gasket, the limiting element is equipped on the top of the screw stem and in the upper screw gasket, and the diameter of the limiting element is slightly bigger than the diameter of the screw stem and the lower screw gasket. The utility model of a gland pressure cooker: 1. the limiting element is provided, the lower screw gasket is lifted and touched with the limiting element when fit the cooker cover and exert pre-tightening force, so that the bigger and permanent deforming of the spring beam ganged with the handle can be prevented, and the pressure can be decreased safely; 2. the service life of a sealing gasket can be prolonged because the cooker cover can be pressed lavishly.
Description
(1) technical field
The utility model relates to a kind of pressure cooker with pressing cover.
(2) background technology
Pressure cooker with pressing cover is a kind of cooking tools commonly used, after pressure cooker with pressing cover is hotted plate, the pot internal gas pressure rises, pot cover can drive spring beam and lift on automatically, if the elastic button pretightning force is excessive when fastening pot cover, rotary handle, spring beam distortion under big lifting power effect is easy to generate permanent deformation also along with increase, and is unfavorable for safety relief when using.
(3) summary of the invention
When overcoming that pressure cooker with pressing cover elastic button pretightning force is excessive in the prior art, after hotting plate, the pot internal gas pressure rises, lift on the spring beam, spring beam permanent deformation easily under acting on energetically, and being unfavorable for the deficiency of safety relief pressure, the utility model provides a kind of pressure cooker with pressing cover that effectively prevents the spring beam permanent deformation, guarantees safety relief pressure.
The technical solution of the utility model is:
A kind of pressure cooker with pressing cover, comprise a pot body, pot cover, handle, spring beam, adjusting device, pressure limiting valve, described spring beam is supported by handle, described adjusting device is by by screw rod, the swivel nut that with screw flight be connected of strut fixation on pot cover, be made up of the handle of swivel nut interlock, described adjusting device also comprises locating part, described swivel nut comprises fixedly connected last swivel nut and following swivel nut, screw rod and following swivel nut are by being threaded, described locating part is installed in the screw rod top, and be in the swivel nut, locating part is slightly larger than the diameter of screw rod and following swivel nut.
Described locating part is a stop screw, and the slightly larger in diameter of described stop screw is in the diameter of screw rod with following swivel nut.
The beneficial effect of pressure cooker with pressing cover described in the utility model mainly shows: 1, be provided with locating part, fasten pot cover apply pretightning force at present swivel nut be raised to when specifying maximum height and locating part offsets, can effectively prevent excessive with the distortion of the spring beam of handle interlock, guarantee that it does not produce permanent deformation, and guarantee safety relief pressure; 2, pot cover can too not press down, and can improve the service life of sealing ring.
(4) description of drawings
Fig. 1 is the structural representation of the utility model pressure cooker with pressing cover.
Fig. 2 is the partial enlarged drawing of the utility model pressure cooker with pressing cover.
(5) specific embodiment
