Detailed description of the invention
A kind of delay cut-off valve of electric pressure cooker, valve body 1 has the hole being socketed on electric pressure cooking saucepan steam outlet pipe, hole internal fixtion has transition seat 14, transition seat 14 has passage 6, the gas outlet of passage 6 is communicated with outlet passageway 12, it is characterized in that: the gas outlet place of described passage 6 is provided with the flexible closure pad 10 of band sealed cavity, flexible closure pad 10 back is provided with temperature control chip 9, the gap forming venting channels is left between the closed position of described flexible closure pad 10 and the gas outlet of passage 6, the size in described gap is set in the position that thermal deformation that when reaching setting-up time, described flexible closure pad 10 and temperature control chip 9 produce covers the gas outlet of passage 6, between flexible closure pad 10 and valve body, be connected with spring 11, the elastic force of described spring 11 leaves sealing seat venthole for promoting flexible closure pad 10.
Described sealing flap 7 is provided with sealed step, sealing seat 5 is connected with at sealed step place, the periphery of described flexible closure pad 10 is positioned over sealed step place, be connected with sealing flap 7 above, be connected with sealing seat 5 below, sealing flap 7 and sealing seat 5 is blocked, by fastening for the periphery of flexible closure pad 10 formation sealed cavity with buckle 8.
One end of spring 11 is connected with transition seat 14.
The structure of sealed cavity can be overall structure, and namely described flexible gasket 10 makes band cavity structure for entirety, and its cavity forms described sealed cavity.
Temperature control chip 9 is Split type structure with flexible closure pad 10, and temperature control chip and flexible closure pad are placed on sealing seat 5 and seal in flap 7, are in clamping connection with buckle.
In above-described embodiment, described flexible closure pad 10 is planar shaped for the closed position closed the gas outlet of passage 6.
The course of work of the present utility model is: electric pressure cooking saucepan heats, steam in pot is by the endoporus of escape pipe 2, outside outlet passageway 16 dump valve, the heat produced during heating is delivered to flexible gasket 10 and temperature control chip 9, air heats in flexible gasket 10 sealed cavity below starts to splash and rises, the sealing surface promoting flexible closure pad 10 moves towards sealing seat venthole 11 place, along with the increase of heat time, when temperature reaches design temperature, temperature control chip 9 produces elastic deformation, by the position of the sealing surface top of flexible closure pad 10 to sealing seat passage 6 gas outlet, as shown in Figure 2, close the gas in pot, enter heating and the vexed meal state of pressurize.After heat time terminates, the temperature in pot slowly declines, and the temperature in the sealed cavity after flexible gasket 10 also follows decline, temperature control chip 9 reinstatement, under the elastic force effect of spring 11, the sealing surface pushing flexible closure pad 10 is returned to the position of opening passage 6 gas outlet, as shown in Figure 3.
