Description

Technical Field

[0001] The invention relates to the technical field of sealing components, in particular to a sealing cover. Background Art

[0002] The steam peeling machine is based on the principle of volume expansion. Under high-pressure and high-temperature steam, the water in the material to be peeled becomes pressurized water. When the high-pressure steam is discharged, the pressurized water in the material evaporates rapidly, separating the skin and meat of the material to be peeled from each other, thereby achieving the purpose of peeling.

[0003] In the prior art, when the steam tank and the sealing cover of the steam peeling machine are matched, they are generally sealed by a sealing ring. The specific structure is generally that an assembly position is provided at the tank mouth of the steam tank, and a cover connection portion is provided on the sealing cover. The sealing ring is embedded in the cover connection portion of the sealing cover. The sealing cover is matched with the assembly position of the steam tank through the cover connection portion, and the sealing ring is elastically abutted and sealed between the cover connection portion and the assembly position. In the above structure, the sealing ring is very easy to twist and deform under long-term pressure, resulting in sealing failure. At the same time, the installation surface of the sealing ring is also easy to loosen and deform, thereby affecting its service life. Therefore, we propose a sealing cover to solve the above problems.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to a person of ordinary skill in the art. Summary of the invention

[0005] The object of the present invention is to provide a sealing cover to solve the problems raised by the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a sealing cover, comprising a cover body, a mounting plate is provided on the cover body, a sealing ring is sleeved on the outer side of the mounting plate, and the contact surface between the sealing ring and the cover body is constructed as a continuous B-shaped protrusion.

[0007] Preferably, the outer side of the sealing ring is aligned with the cover body, and the inner side of the sealing ring is tightly abutted against the mounting plate of the longitudinal portion.

[0008] Preferably, a portion of the bottom surface of the sealing ring is in tight contact with the mounting plate of the transverse portion.

[0009] Preferably, the cover body and the mounting plate are both made of 301 stainless steel or 304 stainless steel.

[0010] Preferably, the sealing ring is made of polytetrafluoroethylene.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention constructs the contact surface between the sealing ring and the cover body into a continuous B-shaped protrusion. When the sealing ring is squeezed and fits with the tank mouth of the steam tank to form a sealing structure, the B-shaped protrusion and the cover body are squeezed against each other to form a multi-layer closed contact surface with gaps on both sides of the closed contact surface. While improving the sealing effect, it reduces the sealing failure caused by the long-term extrusion deformation of the sealing ring installation surface, thereby helping to extend its service life.

[0013] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
