after the valve core assembly is screwed to a set position; aligning the protruding detent 093 of the knob 09 with the second vertical guide slot 0154 of the upper valve body 013; the special-shaped column 091 protruding in the knob 09 is concentric with the special-shaped hole 0102 in the screw shaft 010; the knob 09 slides down to the junction of the second vertical guide groove 0154 and the second transverse guide groove 0151 (i.e. the anti-falling detent 0133), and then rotates into the second transverse guide groove 0151 after being pressed down slightly.
Fourthly, assembling the upper valve body 015 and the lower valve body 015:
1. the positioning clamp 0136 of the upper valve body 013 is aligned with the groove of the lower valve body 015, slides downwards and then rotates and screws in a specified direction.
2. The lower valve body bolt 0153 of the working valve penetrates through the pressure cover surface (the pot cover surface) and is screwed and fixed on the pressure cover from the cover by the slag-isolating nut 016.
The working principle of the embodiment is as follows:
the knob 09 is rotated left and right, the special-shaped column 091 and the valve core assembly in the knob 09 move up and down on the special-shaped column 091 and the second transverse guide groove of the knob 09, and the valve core assembly is driven to move up and down on the first spiral line 0103 and the second spiral line 0134 of the knob 09 under the action of the protruding clamping position 093 of the knob 09.
When the valve core assembly descends downwards, the bottom end of the valve core is in contact with the arc surface 0152 of the air outlet hole of the lower valve body 015, and forms an air valve function with pressure under the action of 011 force of the pressure spring; when the pressure in the cooker reaches the set pressure value of the marking strip 092 of the knob 09, the pressure spring 011 automatically rises, and redundant air pressure is automatically discharged from a gap generated between the bottom end 0124 of the valve core and the arc surface 0152 of the air outlet hole of the lower valve body 015, so that the pressure in the cooker is ensured to be stable. Pressure adjustment is carried out with first helix 0103, second helix 0134 form, can make this kind of work valve have stepless fine setting, can have more humanized culinary art to control.
When the knob 09 is rotated, when the valve core assembly is lifted upwards to a set position, the second reverse buckle 0121 on the valve core body 012 and the first reverse buckle 0101 in the screw shaft 010 act, the bottom end 0124 of the valve core is separated from the arc surface 0152 of the air outlet hole of the lower valve body 015, and the air pressure in the pot is automatically discharged from the gap between the two, so that the cooking work is completed.
During the set cooking pressure, the excess steam is discharged from the air tube, and under the action of a "V" shaped elastic sealing action of a leak-proof sealing ring 014 (the leak-proof sealing ring 014 in the embodiment, which is in a V-shaped structure with the longitudinal section facing outwards): 1) water vapor cannot escape into spiral holes of the valve core body 012 and the guide cylinder 0139 of the upper valve body 013, so that the internal sanitation can be ensured; 2) when the water vapor in the pot is discharged from the air outlet, because the upper valve body 013 shell blocks, the water vapor is stopped in the upper valve body 013 shell and then discharged from the air outlet 0132 of the upper valve body 013 shell, so that the buffer effect is achieved, and the water vapor can not be directly sprayed out. Can achieve the effect of preventing scald.
When a user cleans the working valve, the user only needs to rotate the housing of the upper valve body 013 to separate the upper valve body 013 from the lower valve body 015 by pressing the steering indication mark 0135, and at the moment, only needs to wash the inside of the housing with clean water (the inside of the upper valve body 0137 and the lower valve body 015 are simply and conveniently completed).
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.
