Example Embodiment
[0046] Example 1:
[0047] Figure 5 , Image 6 In order that the sealing ring can move upwards, the elastic body adopts a gradual cylindrical and conical spiral compression elastic embodiment.
[0048] A sealing ring holder 6 is arranged above the sealing ring 4, and a number of spring supports 7 are fixed on the sealing ring holder 6. The spring supports 7 can expand and contract up and down, and the spring supports 7 are equipped with a compression spring 8. The spring 8 can of course be other suitable spring.
[0049] Figure 7 It is a schematic diagram of the installation method of the spiral compression spring and the normal state;
[0050] Figure 8 It is a schematic diagram of the compression spring after the maximum deformation occurs when the safe vapor pressure is above;
[0051] Picture 9 As another spring support type adopted in Embodiment 1, there are many types of spring supports, which cannot be listed one by one.
[0052] The spring deformation characteristic of this e...
Example Embodiment
[0054] Example 2:
[0055] Picture 10 with Picture 11 In order that the sealing ring can move upward, the elastic body adopts an embodiment of an abrupt torsion spring.
[0056] A sealing ring holder 6 is arranged above the sealing ring 4, and a plurality of torsion springs 10 and a balance ring 9 are installed on the sealing ring holder 6. The core shaft of the torsion spring 10 is fixed on the sealing ring holder 6. The balance ring 9 is drilled with a hole at the corresponding position of the end hole of the torsion spring 10, a bolt is fixed in the hole, and the bolt passes through the end hole of the torsion spring 10.
[0057] Picture 12 It is a schematic diagram of the abrupt torsion spring of embodiment 2 in a normal state;
[0058] Figure 13 for Picture 12 A view of the direction.
[0059] The torsion spring 10 has a preset torque and a preset torsion angle. When the steam pressure in the pot is set to a safe pressure (for example, 100KPa), the steam pressure of each to...
Example Embodiment
[0065] Example 3:
[0066] Figure 18 with Figure 19 It is an embodiment in which the sealing ring can move outward (toward the outside of the pot), and the elastic body adopts a gradual tension spring.
[0067] The sealing ring 4 is placed on the edge of the pot body 1 and the lid 2. A number of tension spring rings 11 are arranged on the outside (the spring rings can also be placed in the sealing ring). The two ends of the spring ring should be placed in the ring before connecting. The short cylinder (other supports can also be used) to prop up the spring coil to make the tension spring coil generate a preset internal tension. The internal pressure generated by this tension is equal to the steam pressure in the pot as a safe pressure (for example, 100KPa) ), the steam pressure on the sealing ring. Because of the supporting function of the support in the spring ring, when there is no steam pressure, the spring ring has no pressure on the sealing ring, and the sealing ring and th...
