Abstract
Disclosed is a time-delay shutoff valve of an electric pressure cooker. A flexible closing pad with a sealed cavity is arranged at an air outlet of a vent hole, a temperature control piece is arranged at the back of the flexible closing pad, a gap for forming an air passage is reserved between a closing portion of the flexible closing pad and the air outlet of the vent hole, the size of the gap is set to realize that the position of the air outlet of the vent hole is covered by thermal deformation generated by the flexible closing pad and the temperature control piece when set time arrives, a spring is connected between the flexible closing pad and a valve body, and the elastic force of the spring pushes the flexible closing pad to leave the air outlet of the vent hole. The time-delay shutoff valve has the advantages that a temperature controller is completely isolated from air, the time-delay shutoff valve can be controlled by the aid of the principle of thermal expansion and contraction, the closing pad is supported by the spring, switching time is accurately controlled, and the time-delay shutoff valve is safe and reliable to use.

Technical field
The present invention relates to the safety valve of electric pressure cooking saucepan, more particularly to a kind of delay cut-off valve of electric pressure cooker.
Background technology
The applicant had applied for the delay cut-off valve of electric pressure cooker of correlation, this kind of time-delay shutting valve, time control is carried out using temperature detect switch (TDS) in valve, although the rice process that boils can be changed, it is rational in infrastructure simple, processing and manufacturing and assembly cost are low, but because temperature detect switch (TDS) is connected with gas outlet, occur moisture cause temperature detect switch (TDS) to make moist etc. into temperature detect switch (TDS) there is failure in factor influence, the problems such as delay of response, in addition, because flexible closure pad can slowly be moved with the change of temperature in heating process to the direction of closing gas outlet, in not up to design temperature, sometimes gas outlet can also be covered, have impact on temperature controlled accuracy.
The content of the invention
It is an object of the invention to provide one kind by temperature controller completely and air insulated, and implement to control using shrinkage thermal expansion principle, sealing pad is withstood with spring, with precise control switch time, safe and reliable delay cut-off valve of electric pressure cooker.
Solution of the invention is such：
A kind of delay cut-off valve of electric pressure cooker, valve body has the hole for being socketed on electric pressure cooking saucepan steam outlet pipe, and transition seat is fixed with hole, and the gas outlet that transition seat has passage, passage connects with outlet passageway, it is characterised in that：The flexible closure pad with sealing cavity is provided with the passage gas outlet, flexible closure acting as a cushion portion is provided with temperature control chip, the gap to form venting channels is left between the closing portion of the flexible closure pad and passage gas outlet, the size in the gap is set in the position that the thermal deformation that the flexible closure pad and temperature control chip are produced when reaching setting time covers passage gas outlet；Spring is connected between flexible closure pad and valve body, the elastic force of the spring is the gas outlet for promoting flexible closure pad to leave passage.
More specifically technical scheme also includes：The formation of described sealing cavity includes the flexible closure pad for sealing flap and being connected with sealing flap, and the periphery of the flexible closure pad is tightly connected by sealing seat with the sealing flap, and its inner chamber forms described sealing cavity.
Further：Described sealing flap is provided with sealed step, sealing seat is connected with sealed step, the periphery of the flexible closure pad is positioned at sealed step, it is connected with sealing flap above, it is connected with sealing seat below, sealing flap and sealing seat are stuck with buckle, the periphery of flexible closure pad is fastened to form sealing cavity.
Further：Described flexible gasket is positioned in sealing seat and closure, uses buckle clamping, and its cavity forms described sealing cavity.
Further：One end of the spring is connected with transition seat.
Further：The closing portion that described flexible closure pad is used to close the gas outlet of passage is planar shaped, arc surfaced, spheric, one kind of taper.
It is an advantage of the invention that temperature controller is completely and air insulated, and implements to control using shrinkage thermal expansion principle, sealing pad is withstood with spring, it is safe and reliable with precise control switch time.

Specific embodiment
A kind of delay cut-off valve of electric pressure cooker, valve body 1 has the hole for being socketed on electric pressure cooking saucepan steam outlet pipe, and transition seat 14 is fixed with hole, and the gas outlet that transition seat 14 has passage 6, passage 6 connects with outlet passageway 12, it is characterised in that：The flexible closure pad 10 with sealing cavity is provided with the gas outlet of the passage 6, the back of flexible closure pad 10 is provided with temperature control chip 9, the gap to form venting channels is left between the closing portion of the flexible closure pad 10 and the gas outlet of passage 6, the size in the gap is set in the position that the thermal deformation that the flexible closure pad 10 and temperature control chip 9 are produced when reaching setting time covers the gas outlet of passage 6；Spring 11 is connected between flexible closure pad 10 and valve body, the elastic force of the spring 11 is to promote flexible closure pad 10 to leave sealing seat venthole.
Described sealing flap 7 is provided with sealed step, sealing seat 5 is connected with sealed step, the periphery of the flexible closure pad 10 is positioned at sealed step, it is connected with sealing flap 7 above, it is connected with sealing seat 5 below, sealing flap 7 and sealing seat 5 are blocked with buckle 8, the periphery of flexible closure pad 10 is fastened to form sealing cavity.
One end of spring 11 is connected with transition seat 14.
The structure of sealing cavity can be overall structure, i.e., to be integrally formed band cavity structure, its cavity forms described sealing cavity to described flexible gasket 10.
It with flexible closure pad 10 is Split type structure that temperature control chip 9 is, temperature control chip and flexible closure pad are placed in sealing seat 5 and sealing flap 7, are in clamping connection with buckle.
In above-described embodiment, the closing portion that described flexible closure pad 10 is used to close the gas outlet of passage 6 is planar shaped.
The course of work of the invention is：Electric pressure cooking saucepan is heated, the endoporus that steam in pot passes through escaping pipe 2, outside the dump valve of outlet passageway 16, the heat transfer produced during heating is to flexible gasket 10 and temperature control chip 9, the air heats in sealing cavity behind flexible gasket 10 start to splash and rise, the sealing surface of flexible closure pad 10 is promoted towards moving at sealing seat venthole 11, with the increase of heat time, when temperature reaches design temperature, temperature control chip 9 produces elastic deformation, by the position on the sealing surface top of flexible closure pad 10 to the gas outlet of sealing seat passage 6, as shown in Figure 2, gas in closing pot, into heating and the vexed meal state of pressurize.After heat time terminates, the temperature in pot slowly declines, and the temperature in sealing cavity after flexible gasket 10 also follows decline, temperature control chip 9 is restored, under the elastic force effect of spring 11, the sealing surface for pushing flexible closure pad 10 is returned to the position for opening the gas outlet of passage 6, as shown in Figure 3.
