The regulating valve core has a hollow channel running through its upper and lower sides in the middle; the lower part of the regulating valve core passes through the regulating valve decorative ring, the regulating position, and the first mounting hole and is tightened with the fixing nut, the fixing nut having a first vent hole connecting the hollow channel to the inside of the pot; the shock-absorbing spring is sleeved on the outer periphery of the regulating valve core, its upper end abutting against the first protruding ring, and its lower end abutting against the inner bottom of the regulating valve decorative ring; the second counterweight is sleeved on the outer periphery of the regulating valve core and can slide up and down along it, the first counterweight is sleeved on the outer periphery of the second counterweight and can slide up and down along its outer wall, the inner side of the regulating valve decorative ring has a first annular stage, the first annular stage being located below the first counterweight; the first counterweight is located inside the regulating valve decorative ring and can slide up and down along it; the regulating valve cap is installed above the second counterweight, the regulating valve cap having a second vent hole running through its upper and lower sides, the lower side of the regulating valve cap having a sealing block, the sealing block opening or sealing the outlet of the hollow channel as the second counterweight rises and falls.
[0005] By rotating the regulating valve knob and adjusting the gear adjustment block, the decorative ring of the regulating valve can be raised or lowered, thereby raising or lowering the counterweight block, achieving venting and pressure relief, and regulating the pressure inside the pot.
[0006] The second counterweight has a first channel and a second channel communicating with the first channel. The first channel and the second channel together penetrate the upper and lower sides of the second counterweight. The inner wall of the second channel is recessed towards the outside of the second counterweight to form a first annular groove. An anti-detachment spring is installed in the first annular groove. The upper section of the regulating valve core passes through the first channel, and the anti-detachment spring is located on the outer periphery of the regulating valve core and above the first protruding ring. The anti-detachment spring prevents the second counterweight from falling off the regulating valve core.
[0007] The lower side of the regulating valve cap extends downward to form a first positioning retaining ring. A second annular groove is formed on the inner side of the first positioning retaining ring, and a second protruding ring is formed between the second annular groove and the bottom of the first positioning retaining ring. A third annular groove is formed on the upper outer periphery of the second counterweight, and a third protruding ring is formed between the third annular groove and the top of the second counterweight.

The first inclined surface is a transition surface connecting the top surface of the adjustment gear and the first step, and the second inclined surface is a transition surface connecting the first step and the second step. In a counter-clockwise direction, the sequence is: first inclined surface, first step, second inclined surface, and second step. The height between the second step and the top surface of the adjustment gear is greater than the height between the first step and the top surface of the adjustment gear. The two inclined surfaces, the two steps, and the top surface of the adjustment gear together form a three-layer stepped structure, enabling three-level pressure adjustment. Rotating the adjustment valve knob produces a clear tactile feedback of the pressure level, allowing the user to feel the current pressure level.
[0010] The gear adjustment block is provided in three parts, which are evenly distributed on the same circumference of the top surface of the adjustment gear, so that the force is evenly distributed. The decorative ring of the adjustment valve and the adjustment valve knob can better achieve stable adjustment of lifting and lowering, and realize the function of stable pressure adjustment.
[0011] It also includes a first gasket, which is sleeved on the outer periphery of the regulating valve core and clamped between the shock-absorbing spring and the inner bottom of the regulating valve decorative ring. The first gasket has cushioning properties.
[0012] It also includes a second gasket; the inner bottom of the adjustment position has a positioning groove, and the second gasket is sleeved on the outer periphery of the adjustment valve core and located within the positioning groove; the outer periphery of the adjustment valve core has a second annular surface, and the lower side of the second annular surface abuts against the second gasket. The second gasket provides a buffer between the adjustment valve core and the adjustment position.
[0013] It also includes a sealing ring, which is sleeved on the outer periphery of the regulating valve core and clamped between the fixing nut, the pressure cap and the regulating valve core.
[0014] The top surface of the decorative ring of the regulating valve protrudes outward to form a fifth raised ring. The lower side of the raised ring moves away from or close to the upper side of the fourth raised ring as the decorative ring of the regulating valve rises and falls.
[0015] Compared with the prior art, the advantages of this utility model are: the regulating valve has fewer parts, is easy to assemble, has a three-level pressure regulation function, can increase the sealing inside the pot or release air pressure, and can stabilize the pressure release.
