Abstract
The utility model provides an inflatable seal ring and a fixing device thereof and relates to land vehicles in a nuclear power station. The inflatable seal ring and the fixing device thereof resolve the problems that an annular inflatable hosepipe of an existing sealing device is hard to fasten and affects sealing effect. The inflatable seal ring is disposed between a shielding case and the ground. A cross section of the inflatable seal ring is provided with an inverted triangle solid on an upper portion and an inflatable round or oval thin-walled pipe on a lower portion, and the inflatable round or oval thin-walled pipe is connected with the inverted triangle solid. The fixing device of the inflatable seal ring is composed of an inner press board, an outer press board and sunk screws. Inclined planes of the inner press board and the outer press board are matched with an inclined plane of the inverted triangle solid and fixed on the bottom surface of the shielding case through the sunk screws. The inflatable seal ring and the fixing device thereof are used in the land vehicles in the nuclear power station. A sealed space is formed between gaps of the shielding case and the ground so that heat in the shielding case and a shaft can be conveniently exhausted. Therefore, the gaps between the shielding case and the ground can be maintained so that the shielding case can move corresponding to the ground.
Description
Technical field
The utility model relates to nuclear power station ground car, particularly the seal arrangement between radome and the ground clearance in the nuclear power station ground car.
Background technique
Because China's new energy development in recent years rapidly, plan is a lot of with the nuclear power station project of building.Nuclear power station can produce spentnuclear fuel, and picking and placeing all of var fuel pot can be accomplished with nuclear power station ground car.Nuclear power station ground car is a kind of novel high temperature gas cooled reactor used in nuclear power station crane gear, and the hot air flow that can take vertical shaft in the vent systems of the process ground car that takes out or put into var fuel pot away dispels the heat.Vent systems comprises radome and air extractor etc.When local car moved to the passage that makes radome and is positioned at the position on the nuclear power station vertical shaft just, air extractor can be extracted the hot air flow in radome and the vertical shaft out.In order to prevent the effect of the gap affects discharge hot air flow between radome and the ground, vent systems also comprises seal arrangement.Seal arrangement is fixedly installed on the radome lower end, and can vertically pack up and put down, and can between the gap on radome and ground, form seal space, the heat that convenient discharge radome is interior and vertical shaft is interior; The gap that perhaps can keep radome and ground is so that can relative movement between radome and the ground.
The seal arrangement of existing technology is a kind of gas-filled annular flexible pipe that is fixedly connected on the radome bottom surface.This gas-filled annular flexible pipe though have the sealing function of realizing when putting down between radome and the ground, realizes keeping the function in gap when packing up.Yet, the fixedly ten minutes difficulty of this gas-filled annular flexible pipe, simultaneously, fixing quality directly influences sealing effect.
The model utility content
The purpose of the utility model is intended to overcome the shortcoming of existing technology, and a kind of inflatable seal circle and fixing device thereof are provided, and the gas-filled annular flexible pipe that solves existing seal arrangement is fixed difficulty, influenced the problem of sealing effect.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
A kind of inflatable seal circle; Comprise: be arranged on radome and contain the annular inflatable Sealing between the ground of vertical shaft; It is characterized in that: said annular inflatable Sealing is a kind of inflatable seal circle; Its transverse section: top is the del entity, and the bottom is inflatable circle or the oval thin walled tube that connects as one with the del entity.
Said circle or oval thin walled tube are connected with hose connection, and hose connection is connected with the inflation element again, are used for to said thin walled tube inflation.
Said circle or oval thin walled tube are connected with hose connection, and hose connection is connected with the venting element again, are used for said thin walled tube venting.
Said inflatable seal circle is made by rubber-like elastic material.
A kind of fixing device of inflatable seal circle; It is characterized in that: said fixing device is made up of inner clip plate, outer plate and sunk screw; One side of said inner clip plate is provided with the inner clip plate inclined-plane that matches with first inclined-plane of the del entity of annular inflatable seal ring; Have on the said inner clip plate and fixing use the inner clip plate through hole, one side said outer plate be provided with the outer plate inclined-plane that matches with second inclined-plane of said del entity, have on the said outer plate to fix and use the outer plate through hole; Said inner clip plate, outer plate combine ring by the multistage arc plate respectively, fix with the bottom surface of sunk screw and radome respectively in said inner clip plate through hole, the outer plate through hole.
The utility model compared with prior art has the following advantages and beneficial effect:
Because the top, transverse section of the utility model is the del entity; Rigidity is stronger, and plane can directly be fitted in the radome bottom surface on it, and two inclined-planes match with the inclined-plane of inside and outside two cover pressing plates; Therefore, can seal ring be pressed abd fixed on the radome bottom surface reliably.Because outer plate is an annular in two covers of the utility model, and the multi-section type combination, has both made things convenient for installing and fixing of seal ring, can be easy to remove and repair again.
The utility model is applicable to can form seal space in the nuclear power station ground car between the gap on radome and ground, the heat that convenient discharge radome is interior and vertical shaft is interior; The gap that can keep radome and ground is so that can relative movement between radome and the ground.
