Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a floating stop valve for a steam pressure cooker. Background Technology

[0002] Existing pressure cookers are typically equipped with a self-locking valve, which is one of the core components of their safety system. During cooking, as the pressure inside the pot increases, the self-locking valve automatically activates and locks, both isolating the gas inside the pot to maintain pressure and locking the lid to prevent forced opening, providing dual safety protection. Currently, the most commonly used self-locking valve is the float valve. The float valve uses a springless design, relying entirely on the gas pressure inside the pot to lift the valve core. Its structure is simple and its failure rate is low. However, its disadvantages include the ease with which steam can leak from the valve core, poor sealing performance, and difficulty in disassembly and repair. Summary of the Invention

[0003] To address the aforementioned technical problems in the background art, this utility model provides a floating stop valve that has the advantages of good sealing effect and easy disassembly and maintenance.

[0004] The technical solution of this utility model is as follows: This utility model is a floating stop valve, which is special in that: the floating stop valve includes a valve shell, a valve core, a U-shaped rubber ring and a through-hole bolt. A through hole is provided inside the valve shell, the valve core is set in the through hole of the valve shell, and the top of the valve core can extend outside the valve shell. The U-shaped rubber ring is set in the through hole and is located below the valve core. The bottom of the valve core extends into the U-shaped rubber ring. A through-hole bolt is provided at the through hole at the bottom of the valve shell.

[0005] Furthermore, an outer boss is provided on the lower outer side of the valve core, and an inner boss is provided in the middle of the through hole of the valve shell. The valve core is connected to the top two sides of the U-shaped rubber ring through the outer boss.

[0006] Furthermore, a sealing ring is provided at the bottom of the valve housing.

[0007] Furthermore, the through-hole bolt is movably connected to the through hole via a thread.

[0008] Furthermore, the valve housing includes a first valve housing and a second valve housing, with the second valve housing disposed below the first valve housing.

[0009] Furthermore, the second valve housing is movably connected to the first valve housing via a threaded connection.

[0010] Furthermore, the top outer side of the U-shaped rubber ring is provided with an outer edge, which is engaged between the second valve housing and the first valve housing.

[0011] Furthermore, through-hole bolts are located at the bottom of the second valve housing.

[0012] This utility model provides a floating check valve, which is equipped with a U-shaped rubber ring and a through-hole bolt. Steam is introduced through the through-hole bolt, and the U-shaped rubber ring lifts the valve core, resulting in a good sealing effect. Simultaneously, the valve housing of this utility model includes a first valve housing and a second valve housing. The second valve housing is movably connected to the first valve housing by a thread, and the through-hole bolt is also movably connected to the through hole on the second valve housing by a thread, facilitating disassembly and maintenance. Therefore, this utility model has the advantages of good sealing effect and ease of disassembly and maintenance. Attached Figure Description

[0015] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments: See Figure 1 , 2The structure of this utility model includes a valve shell, a valve core 2, a U-shaped rubber ring 4, and a through-hole bolt 6. A through-hole 9 is provided inside the valve shell. The valve core 2 is disposed in the through-hole 9 of the valve shell, and the top of the valve core 2 can extend outside the valve shell. The U-shaped rubber ring 4 is disposed in the through-hole 9 and is located below the valve core 2. The bottom of the valve core 2 extends into the U-shaped rubber ring 4. A through-hole bolt 6 is provided at the through-hole 9 at the bottom of the valve shell. An outer boss 7 is provided on the lower outer side of the valve core 2. An inner boss 8 is provided in the middle of the through-hole 9 of the valve shell. The valve core 2 is connected to the top two sides of the U-shaped rubber ring 4 through the outer boss 7. A sealing ring 5 is provided at the bottom of the valve shell. The through-hole bolt 6 is movably connected to the through-hole 9 by means of threads. The top of the valve core 2 extends outside the through-hole 9. In this embodiment, the valve housing includes a first valve housing 1 and a second valve housing 3. The second valve housing 3 is located below the first valve housing 1 and is movably connected to the first valve housing 1 by a thread. An outer edge 10 is provided around the top outer side of the U-shaped rubber ring 4. The outer edge 10 is engaged between the second valve housing 3 and the first valve housing 1. A through-hole bolt 6 is located at the bottom of the second valve housing 3 and is threadedly connected to the through hole 9 of the second valve housing 3. A sealing ring 5 is located at the bottom of the second valve housing 3.

[0016] See Figure 3 In a preferred embodiment of this utility model, the steam pressure cooker includes a lid and a pot body 18. The lid 14 is mounted on the pot body 18, and a lid locking ring 17 is located on the outer side of the lid 14. A handle 15 is located above the lid locking ring 17. A slidable drawer 16 is provided inside the handle 15. The center of the lid locking ring 17 and the center of the lid 14 are movably connected by a top bolt 12, allowing the lid locking ring 17 to rotate relative to the lid 14 via the top bolt 12. A bolt washer 13 is provided between the top bolt 12 and the lid locking ring 17. An annular outer protrusion is provided on the outer side of the pot opening of the pot body 18, with outer protrusions spaced apart on the annular outer protrusion. An inner protrusion is provided on the inner side of the lower end of the lid locking ring 17, corresponding to the outer protrusions spaced apart. By rotating the lid locking ring 17, the inner protrusion can be locked below the outer protrusions. When the lid is closed, the inner protrusion at the lower end of the lid locking ring 17 engages in the gap between the outer protrusions. Rotating the handle 15 clockwise rotates the lid locking ring 17, causing the inner protrusion at the lower end of the lid locking ring 17 to screw into the space below the outer protrusions, locking the lid 14. When the lid 14 is opened, rotating the lid locking ring 17 in the opposite direction disengages the inner protrusion from the outer protrusions, placing it in the gap between the outer protrusions, allowing the lid 14 to be opened. The lid 14 has a first through hole, and the float valve 11 is located inside the first through hole. The top of the valve core 2 extends outside the first through hole, and the bottom of the through-hole bolt 6 extends outside the first through hole. The bottom of the handle 15 has a hole corresponding to the position of the valve core 2, allowing the valve core 2 to extend into the hole. The sealing ring 5 is secured between the second valve housing 3 and the first through hole.

[0017] The floating stop valve 11 automatically locks the handle 15 and the pot lid 14. When there is a certain gas pressure inside the pot, the gas enters through the through hole of the through bolt 6 and pushes up the U-shaped rubber ring 4. At the same time, it pushes up the valve core 2 in the middle of the U-shaped rubber ring 4. The valve core 2 goes up and gets into the hole at the bottom of the handle 15. At this time, the pot lid locking ring 17 and the pot lid 14 are locked. When there is no gas pressure, the valve core 2 will fall down automatically, and the pot lid locking ring 17 and the pot lid 14 will be unlocked. Rotating the handle 15 will cause the inner protrusion of the pot lid locking ring 17 to disengage from the outer protrusion of the pot body 18, and the pot lid 14 can be opened.
