Embodiment Construction

[0025] Such as Figure 5 As shown, the disc ring static sealing structure is composed of two first metal parts 1, second metal parts 2, disc rings and threaded connectors that need to be sealed. figure 1 As shown, the first metal part is provided with an inner step 11, a convex sealing step 12 and a convex limiting step 13 in sequence along the center to the periphery; image 3 As shown, the second metal part is provided with an outer step 21, a concave sealing step 22 and a concave limit step 23 in sequence along the center to the periphery, the inner step is compatible with the outer step, and the convex sealing step is compatible with the concave sealing step. The convex limit step is compatible with the concave limit step, and the disc ring is located between the convex sealing step and the concave sealing step. The fastener exerts an axial force through the thread of the convex limit step, so that the convex sealing step is matched with the concave sealing step through t...

Abstract

The invention relates to a static seal structure of a dish-shaped ring. The static seal structure of the dish-shaped ring comprises a first metal part, a second metal part, a dish-shaped ring body and a fastening piece; an inner step, a convex seal step and a convex limit step are mounted on the first metal part in sequence from the center to the periphery; an outer step, a concave seal step and a concave limit step are mounted on the second metal part in sequence from the center to the periphery; the inner step is matched with the outer step; the seal surface of the convex seal step is matched with the seal surface of the concave seal step; the convex limit step is matched with the concave limit step; the dish-shaped ring body is located between the seal surface of the convex seal step and the seal surface of the concave seal step; the fastening piece applies axial force through the convex limit step and the concave limit step. The static seal structure of dish-shaped ring solves the technical problems that the existing static seal realized through welding under ultimate temperature is high in cost and is bad in operability; the static seal structure of dish-shaped ring provides the static seal proposal under ultimate temperature, the structure is simple, the cost is low, and the operation is finished conveniently.

Description

technical field [0001] The invention relates to a static sealing structure, especially a static sealing structure under ultra-high temperature or ultra-low temperature conditions. Background technique [0002] Static sealing under extreme temperature conditions is an important research and development topic. Under high temperature or low temperature conditions, ordinary rubber O-rings or PTFE retaining rings will melt and deform to a certain extent or crack at low temperatures, resulting in seal failure, which requires a new low-temperature resistant sealing structure. At present, the static seal under extreme temperature conditions is usually a welded structure, but the welded structure has high requirements on the quality of the weld, and it is necessary to pass pressure tests, X-ray inspections, fluorescent inspections, etc. to ensure the strength and tightness of the welds under the required conditions, and the cost is relatively high. , the operability is poor, and the...
