Description

Technical Field

[0001] This utility model relates to the technical field of pressure cooker valve accessories, specifically to a pressure regulating valve with adjustable settings. Background Technology

[0002] Pressure cookers are very common in kitchens, and traditional pressure cookers are equipped with pressure regulating valves to adjust the set pressure. However, due to valve core design and assembly issues, the pressure regulation process is inconvenient, inflexible, and cannot achieve precise pressure regulation. For food cooking, precise and controllable pressure regulation ensures the deliciousness and texture of the food. To improve this performance, the traditional pressure regulating valve needs structural improvements. These improvements can enhance the reliability and stability of the pressure regulation process and provide multiple pressure settings to meet user needs. Utility Model Content

[0003] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a pressure regulating valve with a range, which can overcome the technical problem of unstable pressure regulation and improve the operational reliability and stability of the pressure regulating valve.

[0004] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0005] A pressure regulating valve with adjustable positions includes an exhaust pipe, a valve seat, a valve core, and a spring. The exhaust pipe is fixedly mounted on the valve seat, and an adjusting handle is rotatably mounted on the valve seat. The adjusting handle is coaxially engaged with the exhaust pipe and pressed against the valve seat by a spring on the exhaust pipe. The valve seat has adjustable positions, and the adjusting handle rotates to engage with the adjustable positions on the adjustable positions.

[0006] The valve core includes a valve head, a micro-pressure inner valve, an intermediate valve, and an outer valve. The lower end of the micro-pressure inner valve is provided with a groove, and the exhaust pipe is provided with a neck groove. A retaining spring is installed in the groove and engages with the upper limit of the neck groove. The intermediate valve is sleeved on the micro-pressure inner valve and supported by the bottom of the micro-pressure inner valve. The outer valve is sleeved on the intermediate valve and supported by the bottom of the intermediate valve. The valve head is fixedly installed on the top of the micro-pressure inner valve and is used to block the exhaust port of the exhaust pipe.

[0007] The bottom inner side of the adjusting handle is provided with a stepped part, which is used to support and raise the valve core to different heights.

[0008] Preferably, the valve seat is provided with a gear position marking part and multiple gear position steps are provided in the circumferential direction. The multiple gear position steps are evenly distributed, and each gear position step is provided with a retention groove.

[0009] Preferably, the adjusting handle is provided with a flange, and an inner groove is formed on the inner side of the flange to fit the gear step. A slider is provided in the inner groove, and the slider slides and adapts to the gear step.

[0010] Preferably, the stepped portion is provided with multiple steps. In the initial state: the bottom height of the micro-pressure inner valve < the bottom height of the intermediate valve < the bottom height of the outer valve; the working state of multi-level adjustment includes: the stepped portion disengaging from the micro-pressure inner valve, the stepped portion supporting / raising the micro-pressure inner valve, the stepped portion supporting / raising the intermediate valve, and the stepped portion supporting / raising the outer valve.

[0011] Preferably, in the initial state: the height of the top of the micro-pressure inner valve > the height of the top of the intermediate valve > the height of the top of the outer valve.

[0012] Preferably, the valve head includes a top cover, an exhaust port, and a conical head. The exhaust ports are evenly distributed around the outer periphery of the conical head, and a portion of the conical head extends into the exhaust port of the exhaust pipe. The top cover is located around the outer periphery of the exhaust ports.

[0013] Preferably, a gasket is further provided on the exhaust pipe, the gasket fitting between the bottom of the adjusting handle and the inner side of the bottom of the valve seat. Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the valve seat and exhaust pipe are kept fixed. The spring allows the adjusting handle to be subjected to force and rotate against the valve seat, making its rotation stable and reliable. During the rotation, due to the step position, it can be supported and maintained at different heights. The valve core can achieve closure by its own weight, with the valve head against the exhaust port of the exhaust pipe in the initial state. If the air pressure at the exhaust port is high, it will push the valve core. In order to support the valve core at different heights and achieve the purpose of pressure regulation, the different heights of the adjusting handle are changed, and the valve core is supported by the adjusting handle at different positions. The valve core can be flexibly and reliably supported and its height can be changed through the direct sleeve connection structure of the micro-pressure inner valve, intermediate valve and outer valve.

[0015] 2. In this utility model, a retention groove is provided on the gear step, which allows the adjustment handle to be stably held at different gear positions.

[0016] 3. By utilizing the flange and inner groove structure, the adjusting handle can rotate stably on the valve seat, reducing its shaking or wobbling, and making the rotation operation more stable.

[0017] 4. Multi-level steps enable more effective adjustment of different travel distances, meeting users' needs for multiple gear settings;

[0018] 5. By further adding shims, the friction between the adjusting handle and the valve seat can be reduced, which can improve the smoothness of the adjusting handle rotation.

[0019] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0032] Example:

[0033] This invention discloses a pressure regulating valve with adjustable positions, as per an embodiment. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the device includes an exhaust pipe 1, a valve seat 2, a valve core 3, and a spring 4. The exhaust pipe 1 is mounted on the valve seat 2 using a snap-fit ​​method. When used in a pressure cooker, both the valve seat 2 and the exhaust pipe 1 are fixed to the pressure cooker lid. An adjusting handle 5 is rotatably mounted on the valve seat 2. The adjusting handle 5 is coaxially fitted onto the exhaust pipe 1 and pressed against the valve seat 2 by the spring 4 on the exhaust pipe 1. Figure 5 As can be seen, a gear step 21 is provided on the valve seat 2. The adjusting handle 5 is engaged with the gear step 21 by rotation and is at different gear heights. It should be noted that the function of the spring 4 is to push the adjusting handle 5 downward. When the adjusting handle 5 is rotated, the spring 4 can be compressed and placed at different heights.

[0034] Combination Figure 3 , Figure 4 and Figure 5The valve core 3 includes a valve head 31, a micro-pressure inner valve 32, an intermediate valve 33, and an outer valve 34. The lower end of the micro-pressure inner valve 32 has a groove 321, and the exhaust pipe 1 has a neck groove 11. A retaining spring 6 is fitted inside the groove 321 and engages with the upper limit of the neck groove 11. The intermediate valve 33 is sleeved on the micro-pressure inner valve 32 and supported by its bottom. The outer valve 34 is sleeved on the intermediate valve 33 and supported by its bottom. The valve head 31 is fixedly mounted on the top of the micro-pressure inner valve 32 and is used to block the exhaust port 13 of the exhaust pipe 1. The retaining spring 6 prevents the micro-pressure inner valve 32 from easily detaching from the exhaust pipe 1, thus avoiding excessive exhaust pressure in the exhaust pipe 1 that could push the valve core 3 out of the exhaust pipe 1. A step 54 is provided on the inner bottom of the adjusting handle 5, which supports and elevates the valve core 3 to different heights.

[0035] The working principle of this scheme is as follows: the valve seat 2 and the exhaust pipe 1 are kept fixed. The spring 4 allows the adjusting handle 5 to be subjected to force and rotate against the valve seat 2, making its rotation stable and reliable. During the rotation, due to the step 21, it can be supported and maintained at different heights. The valve core 3 can achieve closure by its own weight, with the valve head 31 against the exhaust port 13 of the exhaust pipe 1. If the air pressure at the exhaust port 13 is high, it will push the valve core 3. In order to support the valve core 3 at different heights and achieve the purpose of pressure regulation, the different heights of the adjusting handle 5 are changed, and the valve core 3 is supported by the adjusting handle 5 at different positions. The valve core 3 can be flexibly and reliably supported and its height can be changed through the direct sleeve connection structure of the micro-pressure inner valve 32, intermediate valve 33 and outer valve 34.

[0036] Specifically, the valve seat 2 is provided with a gear position marking section 22 and multiple gear position steps 21 arranged circumferentially. The multiple gear position steps 21 are evenly distributed. Figure 5 As can be seen, each gear step 21 is provided with a retaining groove 23. The gear position markings allow the user to clearly know the operating gear. This solution illustrates four gear positions, three of which are represented by numbers, and one gear position is represented by a graphic symbol. The retaining groove 23 on the gear step 21 allows the adjusting handle 5 to be stably held in different gear positions.

[0037] Specifically, in Figure 6 As can be seen, the adjusting handle 5 is provided with a flange 51, and an inner groove 52 is formed on the inner side of the flange 51 to fit the gear step 21. A slider 53 is provided in the inner groove 52, and the slider 53 slides and adapts to the gear step 21. The structure of the flange 51 and the inner groove 52 allows the adjusting handle 5 to rotate stably on the valve seat 2, reducing its shaking or wobbling, and making the rotation operation more stable.

[0038] Further reference Figure 3 and Figure 4Example: The stepped section 54 has multiple steps. In the initial state (under gravity): the bottom height of the micro-pressure inner valve 32 < the bottom height of the intermediate valve 33 < the bottom height of the outer valve 34. In multi-level adjustment states: the stepped section 54 disengages from the micro-pressure inner valve 32; the stepped section 54 supports / lifts the micro-pressure inner valve 32; the stepped section 54 supports / lifts the intermediate valve 33; and the stepped section 54 supports / lifts the outer valve 34. In the initial state: the top height of the micro-pressure inner valve 32 > the top height of the intermediate valve 33 > the top height of the outer valve 34. The multiple steps enable more effective adjustment of different strokes, meeting the user's needs for multiple levels.

[0039] The valve head 31 includes a top cover 311, an exhaust port 312, and a conical head 313. The exhaust ports 312 are evenly distributed around the outer periphery of the conical head 313. A portion of the conical head 313 extends into the exhaust port 13 of the exhaust pipe 1. The top cover 311 is located around the outer periphery of the exhaust ports 312. A gasket 12 is also provided on the exhaust pipe 1, fitting between the bottom of the adjusting handle 5 and the inner side of the bottom of the valve seat 2. By further providing the gasket 12, the friction between the adjusting handle 5 and the valve seat 2 can be reduced, thereby improving the smoothness of rotation of the adjusting handle 5.

[0040] Example of assembly process in production: First, sequentially install the micro-pressure inner valve 32, intermediate valve 33, and outer valve 34 above the exhaust pipe 1. Then, assemble the retaining spring 6 between the micro-pressure inner valve 32 and the exhaust pipe 1 to complete the locking and limiting. Next, embed the adjusting handle 5 into the valve seat 2, and then place the spring 4 at the bottom center of the adjusting handle 5. Insert the lower end of the exhaust pipe 1 (which is assembled at the top) into the adjusting handle 5 and the valve seat 2, so that the upper end of the spring 4 abuts against the exhaust pipe 1, and the lower end of the exhaust pipe 1 extends out of the valve seat 2. Finally, snap the valve head 31 onto the upper end of the micro-pressure inner valve 32 to complete the assembly. In use, simply fix the lower end of the exhaust pipe 1 in place.

The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations.
