Abstract
The utility model discloses a safety non-open valve mechanism of a pressure cooker. A handle of a pressure cooker is provided with a safety non-open valve which is matched with a valve seat on a cooker cover, wherein the safety non-open valve integrates a non-open mechanism and a safety mechanism into a whole; the end part of the lower end of a valve rod of the safety non-open valve is provided with a rotary body, and the diameter of the rotary body is slightly larger than that of a valve rod of a connecting part; the rotary body is matched with an elastic body valve seat in a penetrating mode, and the elastic body valve seat is arranged on the cooker cover. The utility model skillfully applies an elastic body in the valve seat structure, when the pressure in the cooker exceeds a set value, a smooth body at the lower end of the valve rod of the safety non-open valve emerges from the elastic body valve seat so that the valve seat is formed into a through hole, and consequently, the through hole becomes an air exhausting passage of the pressure air in the cooker. The utility model has the advantages of simple structure and superior danger eliminating effect. The utility model can reliably eliminate a potential safety hazard generated by the pressure which is too high in the cooker, and the pressure is caused by a fault.
Description
Technical field
The utility model relates to the pressure cooker that a kind of family life is used, and especially relates to a kind of improvement of safe stopping valve structure of pressure cooker.
Background technology
In order to guarantee the safe handling of pressure cooker, current in the design of pressure cooker, according to national Specification, all considered only opening mechanism of safety.In the prior art, except that the structure that only opening mechanism and safety valve split, also have above-mentioned two mechanisms are merged into one the plan of establishment, this plan of establishment that unites two into one, compact conformation is arranged, outside the characteristics of outward appearance brevity and lucidity, its weak point is arranged also, as cause adorning safety valve capacity deficiency thereon because of the size of only starting, it is excessive that safety valve begins to be vented to the pressure reduction of opening fully; Also just like cleaning difficulty etc.
Summary of the invention
The purpose of this utility model is: for overcoming the above-mentioned deficiency of prior art, thereby it is big to develop a kind of capacity, the safe stopping valve that uses on the reliable family expenses pressure cooker of security performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the safe stopping valve that uses on a kind of family expenses pressure cooker, contain pot cover, handle is housed on the pot cover, be equipped with on the handle match with valve seat on the pot cover only open the safe stopping valve that unites two into one with release mechanism, it is characterized in that: the end, lower end of described safe stopping valve valve rod have a slightly larger in diameter in the rotary body of its connecting portion stem diameter, be provided with the elastomer valve seat with the corresponding position of safety stopping valve valve rod on the described pot cover, described elastomer valve seat is provided with the interior collar extension that rotary body is closely passed through.
The technical solution of the utility model also can be further perfect, and as preferably, described rotary body is a spheroid.
As preferably, described rotary body is a truncated cone.
As preferably, described rotary body is the butt oliva.
As preferably, described elastomer valve seat is the flute profile valve seat, and its notch is downward.
As preferably, described elastomer valve seat is a planar valve seat.
The beneficial effects of the utility model are: dexterously elastomer is applied in the valve seat construction, when pot inner pressure surpasses setting value, the rotary body of safe stopping valve valve rod lower end is deviate from from the elastomer valve seat, makes valve seat form through hole, thereby becomes the exhaust passage of pot inner pressure gas; It is simple in structure, but the effect brilliance of getting rid of the danger, and can eliminate barrier for some reason reliably and cause the too high and potential safety hazard that occurs of pot inner pressure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is pressure condition schematic diagrames on the pressure cooker.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Pressure cooker as shown in Figure 1, by pot cover 1 and be loaded on the upper handle 2 and the safe stopping valve valve seat 11 of pot cover, valve rod 21 constitutes, valve seat 11 is formed safe stopping valve with valve rod 21, there is rotary body 212 end, lower end of valve rod 21, the rotary body slightly larger in diameter in the diameter of its connecting portion valve rod, rotary body can be spheroid or frustum, it also can be the butt oliva, the utility model adopts spheroid, described rotary body 212 be installed on the pot cover, interior collar extension 111 on the valve seat 11 that the employing elastomeric material is made is closely passed through cooperation mutually, the nominal bore of collar extension in the described elastomer valve seat, be slightly larger than and rotary body connecting portion stem diameter, make the safe stopping valve can be about interior collar extension freedom at its valve rod after the assembling.The elastomeric material of valve seat 11, can adopt temperature resistant rubber or silicon rubber, valve seat 11 can adopt flute profile or planar shaped, the utility model adopts the flute profile valve seat, the interior collar extension 111 of valve seat 11 has formed the pressure cooker internal and external channel, it shown in Fig. 1 the state during no pressure in pot, be that safe stopping valve valve rod 21 falls under the effect of deadweight, only open tongue 23 under the effect of spring 24 forward, making the groove of only opening tongue portion 231 snap in valve rod 21 tops more carefully locates, at this moment, only open apron on the tongue 23 and push away post 232 and back down the pot cover sealing ring, and make pressure cooker be in the safe condition that can not go up pressure.As shown in Figure 2, be to wait to press or go up pressure condition.After closing lid, only open column cap 233 under the effect of lower handle respective guide slots because of what only open tongue 23, to only open tongue and push the rear portion to, and at this moment, only open apron on the tongue 23 and push away post 232 and also remove effect apron, make apron that pot cover, pot body are formed a seal cavity, only open tongue portion 231 backward simultaneously, make the groove on it break away from the thin portion of valve rod 21, the circular hole of only opening tongue portion 231 is aimed at the thicker part of valve rod, at this moment, this pot is in and treats pressure condition.When pot inner pressure rises (about 4kpa), the head 212 of valve rod 21 forms a sealing ring with the interior collar extension 111 of valve seat, make the passage sealing of valve seat 11, thereby make pressure cooker form the space of a complete closed, the thicker part on safe stopping valve bar 21 tops stretches into the circular hole of only opening tongue portion 231 simultaneously, thereby placed restrictions on and only opened tongue 23 and travel forward, at this moment, only opened column cap 233 and also can't from the respective guide slots of lower handle, deviate from and be in lockup state.When pressure cooker causes pressure limiting to lose efficacy because of fortuitous event, pressure can continue to rise, when rising to safety valve qualification pressure, the rotary body 212 of safe stopping valve bar 21 will be released by collar extension in the valve seat of valve seat 11 111, thereby the sealing state of pressure relief pot, the passage of valve seat 11 is opened and exhaust fully, thereby has played the safety guarantee effect.Finish when losing heart, can be easily the rotary body 212 of valve rod 21 to be inserted valve seats 11, the duty for the treatment of that pressure cooker is got back to uncap.
