the valve core body 10 and the pressure spring 09 are placed in the through hole of the valve sleeve 11 from top to bottom, and the cover plate 08 is tightly matched and covered to form a valve core assembly.

Secondly, assembling the upper valve body 03 and the valve core assembly:

1. the release spring 12 is fitted to the valve core assembly housing 11 and then placed in the first mounting hole 031 of the upper valve body 03 from top to bottom.

2. The eccentric wheel 02 is placed in a first mounting hole 031 of the upper valve body 03, the rotating shaft 05 penetrates into a transverse hole 032 of the upper valve body 03, and a second special-shaped surface 051 of the rotating shaft 05 is matched with a first special-shaped surface 022 of the eccentric wheel 02.

3. The knob 04 is tightly fitted on the shaft 05.

4. The top cover 01 is pressed into the first mounting hole 031 of the upper valve body 03 from top to bottom, and the bayonet 012 of the top cover 01 clamps the rotating shaft 05.

Thirdly, assembling the upper valve body 03 and the lower valve body 06:

1. the positioning clamp 035 of the upper valve body 03 is aligned with the groove of the lower valve body 06, slides downwards from the vertical guide groove 064, and then rotates and screws towards the horizontal guide groove 061 in a designated direction.

2. The lower body bolt 063 of the working valve passes through the face of the pressure cover and is screwed to the pressure cover from the inside of the cover by the slag-isolating nut 07.

The working principle of the embodiment is as follows:

1. under the condition of low pressure (in the figure, the number 0 on the upper side of the upper valve body 03 is at a low gear position, namely a first-stage mark position), the knob 04 is rotated rightwards, under the action of the rotating shaft 05 and the eccentric wheel 02, when the cover plate 08 of the valve core assembly is pressed down by the third-stage mark, the second-stage mark and the eccentric point of the first-stage mark of the eccentric wheel 02, the valve core assembly moves downwards, the arc surface at the lower end of the valve core body 10 is contacted and closed with the air outlet 062 of the lower valve body 06, and different pressure values are realized under the action of the pressure spring 09. When the pressure in the cooker is higher than the set pressure value, the pressure spring 09 acts, the valve core body 10 automatically rises, and the air pressure in the cooker is discharged from the air outlet hole 062, so that the air pressure in the cooker is stabilized within the set pressure range value. So that it forms a working valve with pressure.

2. Under the high pressure condition (the number 2 on the upper side of the upper valve body 03 is a high-grade position, namely a third-level mark position), the knob 04 is rotated leftwards, the valve core assembly is lifted upwards under the action of the force of the air release spring 12, when the eccentric wheel 02 rotates to an eccentric point and the third-level mark position is contacted with the cover plate 08, the valve core assembly is moved upwards under the action of the force of the air release spring 12 until the lower end of the valve core body 10 is separated from the air outlet hole 062 of the lower valve body 06, the air pressure in the cooker is discharged outwards, and the pressure in the cooker is equal to the pressure outside the cooker. So that it forms a pressure valve capable of quickly exhausting air.

3. Because the eccentric wheel 02 is in cambered surface transition, the knob 04 is rotated left and right, the transition surface (curved surface) of the eccentric wheel 02 and the top surface of the cover plate 08 of the valve core component enable the valve core component to move upwards or downwards along the cambered surface of the eccentric wheel 02 under the action of the pressure relief spring, and at the moment, the stepless pressure regulation can be realized. More humanized cooking control is realized.

In the set cooking pressure process, redundant air pressure can carry water vapor to be discharged from the air outlet holes 062 of the lower valve body 06 along with the air pressure, when the water vapor in the pot is discharged from the air outlet holes 062, the water vapor is stopped in the outer shell and then discharged from the air outlet holes 034 of the upper valve body 03 due to the blocking of the upper valve body 03, the buffering is achieved, and the water vapor cannot be directly sprayed out. Can achieve the effect of preventing scald.

When a user cleans the working valve, the upper valve body 03 and the lower valve body 06 can be separated only by rotating the upper valve body 03 according to the steering indicating mark 033, and the inside of the shell is simply and conveniently cleaned by only using clear water.

The above detailed description is specific to possible embodiments of the present invention, and the embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention should be included within the scope of the present invention.
