Abstract
The utility model relates to a novel gas-leakage-proof rubber sealing ring used for a household cooker pressure cooker. On the basis of a known small-opening-typed triangular hollow body of large regulas on the external side of the ring connecting the upper and the lower walls of the hollow body with an opening on the inner side, an upper and a lower supporters which are transversally and equidistantly arranged on the inner walls of the upper and the lower walls of the hollow body are additionally arranged, the upper and the lower walls of the hollow body are additionally provided with an upper and a lower arc edges, and the opening on the inner side of the hollow body is a large-opening-typed heart-shaped hollow body. Because of the functions of the upper and the lower supporters, the upper and the lower arc edges and the large-opening-typed heart-shaped hollow body, not only the sealing effect is good, and the service life is extended, but also the utility model is suitable for all pressure cookers of different types and specifications.
Description
The utility model relates to a kind of gasket set that prevents the gas leakage of family cooker pressure cooker, especially a kind of new type rubber seal ring that prevents effectively that pressure cooker gas leakage and working life are very long and be applicable to the pressure cooker of various different models and specification.
Known more handy seal ring of pressure cooker is that China Patent No. is 90211008 at present, " the 88 full-automatic aeration pot circle " of X.Side opening is little open type triangular shape hollow body structure in hollow body upper wall and the hollow body lower wall formation because the big edge strip outside it adopts and encloses connects, lack working substance and support hollow body, when the circle body raw materials use a specified time to wear out deliquescing, hollow body promptly shrinks voluntarily and closes up, inflation and leaking air no longer, working life is not very long.And according to its product introduction and the actual proof of using, it is better that this circle is used for double happiness board pressure cooker, and the different model of producing for different manufacturers and the pressure cooker of specification are then undesirable.
The purpose of this utility model provides a kind of to pressure cooker good sealing effect, long service life and be applicable to the new type rubber seal ring of all pressure cookers of various different models and specification.
The purpose of this utility model is achieved in that the big edge strip (1) in the circle outside connects hollow body upper wall (2) and hollow body lower wall (3); The hollow body upper wall
003(2) with on half position of the inwall of hollow body lower wall (3) respectively be connected upper support body (4) and lower support (5), be equidistant cross setting; Side opening in the hollow body is big open type heart shape hollow body; Go up each at hollow body upper wall (2) and hollow body lower wall (3) and is connected arc limit (6) and arc limit (7) down, be the horn mouth shape of slightly past curls inward.When doing pressure cooker sealing use, upper support body (4) is subjected to pot cover pressure with lower support (5) and touches and close, hollow body promptly forms the ventilating hole (8) of lattice one lattice, because upper support body (4) only accounts for hollow body half position approximately with lower support (5), second half then is that full circle connects, and the interior vapor pressure of pot will be charged into by ventilating hole (8) and make hollow body upper wall (2) and hollow body lower wall (3) distending and play seal action like this.Supporting hollow body upper wall (2) piecemeal owing to upper support body (4) and lower support (5) are equidistant and be a permanent firm integral body with hollow body lower wall (3), so both made still can keep original shape after the ageing of rubber deliquescing and continue to use, thereby increased the service life greatly.In addition, last arc limit (6) reaches down, and arc limit (7) seals on the arc wall of seal groove in the pot body, not only play the effect of enhanced leaktightness, also play following two kinds of effects on the other hand: 1, owing to can shrink the weakness that diminishes after the rubber multiple high temp uses, hollow body upper wall (2) and hollow body lower wall (3) are after aging deliquescing, when just hot steam is not enough in the pot, not too fit with pot body seal groove, water vapor can release along the slit of not too fitting and leak gas, wait until in the pot big just distending sealing when sufficient of big hot steam, and last arc limit (6) and following arc limit (7) are owing to vertically seal on seal groove arc wall, thereby having solved this weakness, this also is a kind of assurance that increases the service life greatly.2, the seal groove gap size of the pressure cooker of each manufacturer production is different, hollow body upper wall (2) and hollow body lower wall (3) seal groove are therewith fitted and are not too fitted with those seal grooves very much, the gas leakage during distending may (not by the time in the pot during the big sufficient and distending of big hot steam, this problem has not just existed naturally) as yet thereby first hot steam deficiency to occur in the pot.Arc limit (7) all is higher than hollow body upper wall (2) and hollow body lower wall (3) because last arc limit (6) reaches down, utilizes this height difference just can address this problem, thereby is applicable to any pressure cooker of various different model different sizes.
Owing to adopt such scheme, good sealing effect not only, and can increase the service life greatly, all pressure cookers all can be suitable for.Production mould is easy, the output height.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is new type rubber seal ring embodiment's an overall structure schematic representation.
Fig. 2 is the sectional elevation of Fig. 1.
Digital declaration of will is as follows among the figure: 1, big edge strip, 2, the hollow body upper wall, 3, the hollow body lower wall, 4, the upper support body, 5, lower support, 6, go up the arc limit, 7, arc limit down, 8, ventilating hole.
In Fig. 1 embodiment shown in Figure 2, big edge strip (1) connects hollow body upper wall (2) and hollow body lower wall (3).The inwall of hollow body upper wall (2) and hollow body lower wall (3) respectively is connected upper support body (4) and lower support (5); The purpose of lower support on the branch is in order to make support short and hard, still can to play a supportive role when ageing of rubber; Last lower support symmetry, purpose is when the pot cover of packing into uses, can touch to close once pot cover extruding and form one complete support, prop up hollow body upper wall (2) and hollow body lower wall (3) with this, shrink the weakness of closing up to solve ageing of rubber deliquescing hollow body, upper support body (4) and lower support (5) are equidistant cross setting, and purpose is more effectively to play a supporting role for more firm; The position of upper support body (4) and lower support (5) is in the inboard of the inwall of hollow body upper wall (2) and hollow body lower wall (3), account for a halfwidth of hollow body, purpose is, on the one hand, last lower support can form the ventilating hole (8) of lattice one lattice piecemeal after closing when touching, do not make the circulation of support blocking-up vapor pressure on the other hand again, second half space connects full circle, make vapor pressure bring into play the expansive force effect rapidly, it is in order to increase the service life that the lower support general purpose is set.Side opening in the hollow body is big open type heart shape, and purpose is to make steam charge into hollow body in a large number rapidly, and has more distending power because of the special shape structure of heart shape.On hollow body upper wall (2) and last arc limit (6) and the following arc limit (7) of respectively being connected of hollow body lower wall (3), be slightly toward involute horn mouth shape, its effect is: fit in enhanced leaktightness effect on the interior seal groove arc wall of pot body, can also utilize its above height difference of hollow body upper wall (2) and hollow body lower wall (3) solve when the initial heat vapor pressure also is not enough to distending the ageing of rubber pot in gas leakage may, the gas leakage that reaches the different pressure cooker of seal groove gap size that different manufacturers produces is possible.Arc limit general purpose is for the enhanced leaktightness effect about being provided with, and increases the service life, and is applicable to all pressure cookers of various different models and specification.
