Abstract

The utility model discloses a pressure limited valve of a pressure cooker, which is sanitary and safe, and is convenient in use with a low gravity center and an inclined channel, comprising a pressure valve and an exhaust pipe. The weight of the pressure valve is lower than the weight of the old pressure valve. The exhaust channel on the pressure valve is inclined. The hand holder is flat, and the edge is projecting and rough. The length of the exhaust pipe which is exposed outside of the surface of the cooker lid is within 20 millimeters. The weight and the exhaust pipe are provided with a locking pin and a locking slot respectively. The utility model is used with the experimental models of the safe and sanitary pressure cooker lid which is easy to put of the Chinese patent 92214605.5 and the pressure cooker lid of the 92238428 for a year, and the effect is good.

Description

Pressure limited valve of pressure looker

The utility model belongs to a kind of cooker, is a kind of pressure-limit valve of pressure cooker specifically.

At present, the pressure cooker overwhelming majority on the China market all is to take weight formula pressure-limit valve.Disappointing passage on the pressure valve of this pressure-limit valve is parallel, rushing water horizontal line four is penetrated when hotting plate, pollute kitchen range top stove and accessory, and its outlet pipe exposes the length on pot cover surface more than 20 or 20 millimeters, add the adept towering projection above it, and pinch hold part down big little smooth smooth, once have oil or water just to pinch incessantly on hand, very sliding.

The purpose of this utility model is that rushing water water can parallel four not be penetrated when a kind of use will be provided, and safety coefficient is higher, adept steady not only health, safety but also the limiting valve of pressure cooker easy to use pinched easily.

The purpose of this utility model is achieved in that the enlarged-diameter with the pressure valve in the old-fashioned pressure-limit valve, reduced height, the passage that loses heart changes the passage of declivity from inside to outside into by substantially horizontal, simultaneously with outlet pipe in the shorten length to 20 on pot cover surface millimeter, adeptly change into flatly, it is outstanding to be used to pinch the edge of holding part, rough surface, make it become centre of gravity, access ramp, pressure-limit valve easy to use.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the sectional view of new-type limiting valve of pressure cooker structure

Fig. 2 is the worm's eye view of new-type limiting valve of pressure cooker

Fig. 3 partly cuts open comparison diagram for new, old two kinds of limiting valve of pressure cooker

(a) old-fashioned (b) is new-type

As shown in Figure 1, the utility model is made up of pressure valve 1 and blast pipe 2 two parts. The lower end of pressure valve 1 is the weight 4 of metal, and the upper end is nonmetal making. Comparatively flat, the edge is outstanding and shaggy adept 5, and there is air chamber 6 at the center of

weight

4, and 4 lateral surface has from air chamber 6 to weight The disappointing passage 7 of several declivities has the stop pin 8 of a spring power or slotting formula from a certain lateral surface of weight 4 to air chamber 6, there is needle 9 at the center of air chamber 6; Blast pipe 2 is respectively top 10 and the bottom below the pot cover surface 11 of exposing pot cover 3 surfaces, the center is air flue 12, the length on the top 10 of blast pipe 2 is less than 20 millimeters, diameter is bigger than the diameter of bottom 11, the lock slots 13 that ring-type is arranged above the top 10, bottom 11 have external screw thread and porous exhaust nut 14 to be complementary.

As shown in Figure 2, certain side of weight 4 of the present utility model has the stop pin 8 of a spring power or slotting formula, center that air chamber 6 and needle 9 are arranged, and air chamber 6 has several disappointing passages 7 to the outside of weight 4.

As shown in Figure 3, the pressure valve 1 of new-type and old-fashioned limiting valve of pressure cooker is respectively by weight 4, and is adept 5, air chamber 6, needle 9 and form to the disappointing passage 7 of declivity or parallel disappointing passage 15 and stop pin 8; Blast pipe 2 is made up of top 10 and bottom 11, lock slots 13 and the porous exhaust nut 14 below pot cover 3 surfaces that blast pipe exposes pot cover 3 surfaces.

Embodiment: fastening porous exhaust nut 14 is fixed on outlet pipe 2 above the pot cover 3, to press the needle 9 in valve 1 air chamber 6 to be pressed on the air flue 12 of outlet pipe 2, and with in the stop pin 8 insertion locking slot 13, make and press valve 1 both to be unable to do without outlet pipe 2, up and down gap is arranged again, not only protect the normal position of holding valve 1 but also prevent to press valve 1 to be dashed " flying " suddenly by highpressure; The interior rushing water water of pot entered air chamber 6 by the air flue 12 of outlet pipe 2 when pressure cooker used, and released above the pot cover 3 of outside from oblique below through the passage 7 that loses heart again.

The applicant supports the use the Chinese patent of the utility model and I application No. 922146055 " the easy placement force pot cover of safety and sanitation " and the preproduction of No. 922384283 " pressure cooker lid " two patents more than a year, effect is splendid, and is especially in the following areas particularly remarkable:

1, not only reduced the chance that blast pipe clashed into after blast pipe shortens but also made that " safety and sanitation are easy The placement force pot cover " or the pot cover of " pressure cooker lid " top in " low ebb " be unlikely to low, can fully keep the useful space in the pressure cooker.

2, a stirred water concentrates on the pot cover after releasing in the pot, can parallel four penetrate.

3, the center of gravity of pressure valve is low, and stationary performance is good.

4, adept easily the pinching surely on the pressure valve can be because of not having oil or water landing on hand.

5, locking device can prevent to press valve to be dashed " flying " suddenly by highpressure, causes the accident.

The utility model proves that through repetition test more than a year its outlet pipe exposes the length on pot cover surface is advisable at 10～15 millimeters, if its length of installation locking device is more suitable in 15 millimeter.
