Abstract
The utility model relates to a sealing rubber ring for pressure cookers. A plurality of arc-shaped notches are arranged on the outer edge of the base ring of the Y-shaped sealing rubber ring of an ordinary pressure cooker. Small grooves are arranged on the inner edge of both wings of the sealing rubber ring corresponding to the notches. When the air pressure in the pressure cooker is larger than the safety pressure, the sealing rubber ring arranged on the part can be propped out of the edge of the cooker body by the pressure in the cooker, and the overpressure air can be quickly exhausted, which ensures the safe use of the pressure cooker. The utility model has the advantages of low cost, high safety, convenient use, etc. The utility model can be matched with a household pressure cooker.
Description
The utility model relates to a kind of pressure cooker O-ring seal.
Now, the a large amount of O-ring seals that use of pressure cooker are Y types, Chinese patent 96223319.6, notification number CN2279508Y, Granted publication day 980422, the applying date 961228, " pressure cooker security seal cushion rubber " by name discloses a kind of pressure cooker security seal cushion rubber, it has several arc-shaped notch at the base circle outward flange of usual pressure pot Y type O-ring seal, abnormal conditions such as exhaust outlet obstruction occur when pressure cooker, when the pressure cooker pot inner pressure surpasses safe pressure, the distortion of arc-shaped notch part cushion rubber is extruded, rubber sealing lost efficacy and lost heart, but the easy crumple of this kind cushion rubber is stuck, and was unfavorable for exhaust under the fortuitous event.At present, lack a kind of can be when pot inner pressure surpasses safe pressure, O-ring seal seal failure effectively automatically and play the new type of safe O-ring seal of the effect of losing heart.
The purpose of this utility model provide a kind of can be when pot inner pressure surpasses safe pressure, O-ring seal seal failure effectively automatically and play the new type of safe O-ring seal of the effect of losing heart.
The utility model is achieved in that a kind of gasket cement of pressure cooker circle, and it has several arc-shaped notch at the base circle outward flange of usual pressure pot Y type O-ring seal, is characterized in: and have little groove at the relative cushion rubber both wings inward flange of recess.
Described little groove length, width are less than 1/3rd of both wings width.
It is low to the utlity model has cost, safe and reliable advantage, when pot inner pressure surpasses safe pressure, arc-shaped notch part cushion rubber distortion is extruded, and the little groove of inner edge is convenient to the cushion rubber distortion and is extruded, and prevents that the cushion rubber crumple is by screens, rubber sealing lost efficacy and lost heart like this, losing heart speeds up, and can make pot inner pressure quickly fall to safe pressure, thereby guarantees the pressure cooker safe handling.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model schematic diagram.
Fig. 2 is an A-A profile of the present utility model.
Gasket cement of pressure cooker circle of the present utility model, it is that base circle outward flange at usual pressure pot Y type O-ring seal has several arc-shaped notch 1, and have little groove 2 at the relative cushion rubber inward flange of recess, recess, groove location are in pot cover uncovered tooth position when using, the length of little groove, width are less than 1/3rd of both wings width, with 1/4th to 1/8th is that good, such O-ring seal can play sealing function in operating pressure.When the pressure cooker pot inner pressure surpasses safe pressure, pot inner pressure can collapse the body edge that takes the dish out of the pot with band arc-shaped notch cushion rubber partly, the little groove of inner edge has accelerated to collapse effect, accelerated drainage overvoltage gas velocity, the sealing cushion rubber has advantages such as cost is low, easy to loading and unloading, safe in utilization, can with the supporting use of family's pressure cooker.
