Abstract
The subject matter of the present invention is a safety valve and anti-radiation device comprising a safety valve (1) and an anti-radiation partitioning or opening and closing member (2) comprising a main structure made from radiation shielding material (3) extending between the opposing faces (2a) or (2b) of said member and a fluid passage cavity (4) closed by said valve and traversing the member, emerging on each opposing face by means of an opening (4a) or (4b). The device comprises at least one shield (5a) or (5b) fixed to one or the other of said opposing faces, comprising an additional or complementary structure made from radiation shielding material (3') or (3") covering one of said openings in such a way as to stop or block any radiation likely to cross the cavity and/or the member while allowing the passage of a fluid under overpressure into said cavity with a view to allowing it to be discharged.
Description
The present invention relates to be intended to the valve (soupape) that uses in the radiation proof switch of radiation-resistant dividing plate, wall or door leaf type or partition member or the field of safety-valve, a kind of safety-valve device of radiation proof protection is provided.
Switch or partition member (hereinafter to be referred as member) comprise two relative faces, and the closing and/or separate (cloisonnement) state of described member, each face extends in a side of described member or space, opposite side place.Such member is also designed to fire-proof or for the Fluid Sealing of liquid state or gaseous state.
In addition, the member of known such one type, wherein its thickness axially on the fluid passage lumen of traversing is set, described chamber is closed by safety-valve, to allow to add liquid state or the gaseous fluid depressed, in one of them space at the place, side of described member, by described chamber, is discharged in another space.The discharge of fluid makes to reduce the pressure in pressurization space, and is reduced to acceptable level, avoids pressurization space or its object comprising to damage.
Such safety-valve is designed to be suitable for close and be biased (sollicit é e) when the pressure of pressure fluid in one of them space is greater than the setup pressure value of valve in rest position become ad hoc fashion to open, this is in order to open channel lumens and to make fluid pass chamber and member, to it is discharged to another space.Described safety-valve is equipped with closing element, for example valve (clapet, valve) or tearable rupture of membranes, and they can move respectively or tear under the overvoltage effect of fluid.
The member of known such one type also, it is designed to form radiation-resistant barrier, α for example, beta, gamma and neutron irradiation.Such radiation proof member has the thickness of radiation proof protective material structure, is included in one or more radiation proof protective materials that extend between relative two faces of described member, for example steel, lead or paraffin.Member is stoped the structure of radiation proof protective material when closing and/or separate state or block radiation is propagated towards member, prevent simultaneously it from a space through and by another space.The thickness of material structure is substantially equal to the thickness of described member, or is less than the thickness of described member.
In the situation that described radiation proof member comprises the fluid passage lumen of being closed by safety-valve, described valve also crosses the thickness of radiation proof protective material structure.
In addition, according to the incident angle of radiation propagation axle, radiation propagation axle can be more or less and the length of radiation proof protective material structure intersect (couper).More specifically; when propagation axis is parallel to the normal of plane at one of opposite face place of described member; the length of the radiation proof protective material structure intersecting with described axle equals the thickness of described structure; but when propagation axis is during with respect to described normal slope, the length of the radiation proof protective material structure intersecting with described axle is greater than the thickness of described structure.
But, in the situation that member comprises the fluid passage lumen by valve closing, when radiation propagation axle and described chamber and above-mentioned member intersect, there is a problem.Because; in this case; according to the incident angle of propagation axis and the inlet point that enters described chamber; described propagation axis can intersect with the length of radiation proof protective material structure that is less than the thickness of radiation proof protective material structure; therefore; the quantity not sufficient of protective material to be to stop or to stop the corresponding radiation through chamber and member, may have weakening more or less.
The present invention seeks to overcome these defects.
For this reason, the invention provides a kind of safety-valve device of radiation proof protection, comprise safety-valve and radiation proof switch or partition member, described member comprises two relative faces (being first surface and the second face), the main structure of the radiation proof protective material extending between described relative face and by the fluid passage lumen of the described valve closing in stationary state, above-mentioned chamber is through described member and said structure, by the first opening, lead to first surface and lead to second by the second opening simultaneously, while opening described valve with box lunch with ad hoc fashion, allow pressure fluid (or crossing hydraulic fluid) to discharge through described chamber, with and feature be mainly, described device also comprises two protectors, each protector comprises that radiation proof protective material adds or supplementing structure, described or each protector can be when covering first surface or second 's the part that comprises the first corresponding opening or the second opening be fixed on first surface or second by stationary installation, reserve the spacing (espace that is formed on the fluid passage between described or each protector and corresponding first surface or second simultaneously, space) gap, to stop on the one hand or stop any radiation that may pass described chamber and/or described member, allowing on the other hand to add the described fluid of depressing discharges by (flowing through) via described gap.
