Description

Sealing ring and steam valve

Technical Field

The utility model relates to a sealed technical field especially relates to a sealing washer and steam valve.

Background

The sealing ring of the existing electric cooker steam valve in the current market is difficult to install, and the sealing ring is easy to fall off in the motion process of the steam valve.

SUMMERY OF THE UTILITY MODEL

To the not enough of sealing washer among the above-mentioned prior art electric rice cooker steam valve easy drop in the motion, the utility model aims to provide a sealing washer, its assembly is simple, and the structure is reliable, is difficult for droing in the motion process, and user experience is good.

The utility model provides a sealing ring, which comprises an annular body, wherein the outer wall of the annular body is provided with an annular groove, and the width of the bottom of the annular groove is larger than that of the top of the annular groove; at least one annular convex rib is arranged on the inner wall of the annular body.

Preferably, the tops of the two side walls of the annular groove extend oppositely along the axial direction of the annular body to form two claws.

Preferably, the annular ribs are two, and the two annular ribs are respectively arranged at the top and the bottom of the inner wall of the annular body.

Preferably, the two annular ribs are equal in height.

The utility model also provides a steam valve, include as above the sealing washer.

Compared with the prior art, the utility model provides a sealing washer assembly is simple, and the structure is reliable, is difficult for droing in the motion process, and user experience is good. The sealing ring provided by the utility model can be fixed by arranging two clamping jaws, so that the sealing ring is not easy to fall off in the process of the vertical movement of the steam valve; through setting up two annular protruding muscle, play double seal's effect, can not increase the sealing washer simultaneously and by the resistance between the sealing member. The sealing ring is designed symmetrically, and can be installed in any direction without dislocation.

The above-mentioned technical characteristics can be combined in various suitable ways or replaced by equivalent technical characteristics as long as the purpose of the invention can be achieved.

Description of reference numerals:

1. a seal ring; 2. a guide post; 3. a fixed seat; 4. a guide post sleeve; 5. flanging ribs; 11. an annular body; 12. an annular groove; 13. an annular convex rib; 14. a first jaw; 15. a second jaw.

Detailed Description

For making the purpose, technical solution and advantages of the present invention clearer, it will be right below that the technical solution of the present invention is clearly and completely described, based on the specific embodiments of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the scope protected by the present invention.

As shown in fig. 1 and 2, the utility model provides a sealing ring 1 includes an annular body 11, and the outer wall of annular body 11 is provided with annular groove 12, and the width of annular groove 12 bottom is greater than the width at annular groove 12 top, can utilize the lateral wall sealing washer 1 of annular groove 12 to fix and spacing. At least one annular convex rib 13 is arranged on the inner wall of the annular body 11, and the annular convex rib 13 is used for sealing a part sleeved in the sealing ring 1.

In one embodiment, as shown in fig. 2, two annular ribs 13 are provided at the top and bottom of the inner wall of the annular body 11, respectively, and the heights of the two annular ribs 13 are equal. The provision of two annular ribs 13 may serve a double sealing function.

In one embodiment, as shown in fig. 2, the tops of the two side walls of the annular groove 12 extend oppositely in the axial direction of the annular body 11, forming a first jaw 14 and a second jaw 15.

The utility model provides a sealing washer 1 can be applied to in electric rice cooker's steam valve. The steam valve of the electric cooker is driven by the guide post 2 which can move up and down so as to move up and down, and the sealing ring 1 is sleeved on the guide post 2 for sealing. Specifically, as shown in fig. 3, a guide post sleeve 4 is arranged on a fixed seat 3 of the steam valve, and the guide post 2 is inserted into the guide post sleeve 4 and can move up and down; at least two flanging ribs 5 are arranged on the inner wall of the guide pillar sleeve 4 of the fixed seat 3, and the two flanging ribs 5 correspond to the annular groove 12 on the sealing ring 1. When the sealing ring 1 is installed, the first clamping jaw 14 and the second clamping jaw 15 are clamped on the two flanging ribs 5, and the two annular convex ribs 13 on the inner wall of the sealing ring 1 are in interference fit with the outer wall of the guide pillar 2. When guide pillar 2 up-and-down motion, two annular protruding muscle 13 play sealed effect to guide pillar 2 outer wall, simultaneously because of annular protruding muscle 13 is very little with guide pillar 2's contact surface, can not increase the resistance when guaranteeing sealed. And two annular convex ribs 13 are arranged, so that double sealing performance is ensured. When the guide pillar 2 moves upwards, the sealing ring 1 is pulled upwards, the second clamping jaw 15 plays a role in tensioning, and the sealing ring 1 is not easy to fall off; when the guide post 2 moves downwards, the sealing ring 1 is pulled downwards, at the moment, the first clamping jaw 14 plays a role in tensioning, and the sealing ring 1 is not easy to fall off.

The utility model provides a sealing washer 1 can also be used for sealing other column parts that can up-and-down motion.

The sealing ring 1 has simple and reliable structure and good sealing performance; and the sealing ring 1 is designed symmetrically, and can be installed in any direction without dislocation.

Finally, it should be noted that: the above embodiments and examples are only used to illustrate the technical solution of the present invention, but not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments and examples, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments or examples may still be modified, or some of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments or examples of the present invention.
