Embodiment Construction

[0013] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Please refer to the attached figure 1 , The device is composed of five components, including a limit clip 1, a side gate 2, a gate bracket 3, a limit left wedge 4 and a limit right wedge 5. The connection sequence is assembled with the gate bracket 3 as the center point; secondly, the limit left wedge plate 4 and the limit right wedge plate 5 are installed in the groove of the gate bracket 3 and closely attached to the inner surface to ensure that the left and right sides are parallel. The center of the center hole of the wedge plate 4 is not concentric with the gate bracket 3 and is in a state of incision; then the side gate 2 is assembled in the center hole of the gate bracket 3, and is in contact with the left and right sides o...

Abstract

The invention discloses a nuclear secondary tight-sealing high-temperature medium combined gate which comprises a gate bracket and two side gates. The left and right sides of the gate bracket are respectively equipped with a limiting left wedge plate and a limiting right wedge plate. The side gates pass through the limiting left wedge plate and the limiting right wedge plate to be connected to thegate bracket, and the side gates are sealingly connected to the gate bracket. Compared with the prior art, the invention has the advantages that the medium leak is prevented through the two side gates and a gate component sealing channel, the downstream process of a pipeline is not affected, a condition that the gates have leak in a high temperature environment or the gates are tightly closed andcannot be normally opened is avoided, in addition, the sealing effect of a valve can be ensured well.

Description

technical field [0001] The invention relates to a flashboard, in particular to a nuclear secondary tightly sealed high-temperature medium composite flashboard. Background technique [0002] It has good heat transfer performance in high-temperature media, especially liquid sodium media, and has high resistance to radioactive radiation and thermal damage. It is an ideal heat transfer medium for reactor systems. However, liquid sodium is very active and can react with many elements that exist in the normal external environment, and has the possibility of fire or explosion. As a liquid sodium medium system, the sealing function must be realized with high reliability during the entire working period. As a pipeline valve, the first function is to open and close the medium to cut off the pipeline medium. Therefore, when the pipeline is cut off, it is ensured that the seal will not leak, so as not to affect the downstream process and prevent the middle port from leaking. [0003] ...
