Abstract
The utility model relates to the field of valve detection, and particularly discloses a valve fitting refinishing room, wherein a compartment is internally provided with an air shower, thus reducing pollution of radioactive substances on environment caused by the flowing of overhauling staffs to the greatest extent; due to the arrangement of an exhaust hood, possible radioactive substances generated in the fitting process are led into an exhaust system of a hot workshop through a sub-high-efficiency filter air outlet and then discharged after filtering and purification; and a large-area glass observation window is arranged on the side wall of the compartment, thus being convenient for the overhauling staffs to observe the ambient environment of overhauling objects and the valve fitting refinishing room, and simultaneously being convenient for lighting of the fitting room. The valve fitting refinishing room has high practicability, provides convenience for the overhauling staffs, reduces the operation and maintenance cost of a nuclear power station, improves the maintenance quality and has high safety.
Description
Technical field
The utility model belongs to valve maintenance field, is specifically related to a kind of valve-seating trimming equipment.
Background technology
After nuclear power station puts into operation, overhaul the zone that be subjected to radioactive pollution equipment owing to lack a centralized and unified decontamination at cold-refueling between turn(a)round, the various equipment that need maintenance (as pressurizer safety valve, ratio spray valve, pressure-relief valve, pile against the wind machine and various nuclear level security valve, damper etc.) all are dispersed in the different zone of nuclear island factory building and overhaul on the spot, lack necessary decontamination device and safeguard procedures, thereby produce that possible radioactive pollution enlarges and maintainer's security is difficult to be guaranteed.The crane gear that lacks not only can exert an influence to maintainer's security and Plant maintenance quality, and can prolong the whole time between overhauls(TBO).External experience shows that the time between overhauls(TBO) of ripe nuclear power station generally just can finish in three weeks.Thereby the essential maintenance progress of accelerating, shorten the time between overhauls(TBO), to improve the economic benefit in power station.
Summary of the invention
The purpose of this utility model is to provide a kind of airborne dust and the radioactive substance of maintainer in valve maintenance process of lapping that can prevent to leak, and reduces to greatest extent between the valve-seating trimming of the pollution that radioactive substance brings external environment with flowing of maintainer.
The technical solution of the utility model is as follows:
Between a kind of valve-seating trimming, it comprises two steel construction compartments that communicate, and one of them compartment is provided with stainless steel and opens the door, and is provided with exhaust hood in the compartment, and the compartment outer wall is provided with the filtering inlet air case, is provided with Airshower chamber in the described compartment.
In between above-mentioned valve-seating trimming, described exhaust hood, the capouch that comprises a back taper, capouch is provided with the bellows that is communicated with it, bellows is provided with and filters the air draft case, be connected with electric pushrod on the described capouch, the upper end of electric pushrod is connected on the hard-wired support, and this support is connected on the bellows.
In between above-mentioned valve-seating trimming, be provided with hole for hoist at the top of compartment.
In between above-mentioned valve-seating trimming, be provided with Cleaning luminaire in the described compartment.
In between above-mentioned valve-seating trimming, described compartment sidewall is provided with stainless steel glass window.
In between above-mentioned valve-seating trimming, be provided with holding tank in the described compartment.
The beneficial effects of the utility model are: Airshower chamber is set in the compartment, reduces the pollution that radioactive substance brings environment with flowing of maintainer to greatest extent; By exhaust hood is set, the possible radioactive substance that produces in the process of lapping is passed through the exhaust system that the inferior high efficiency filter exhaust outlet inserts hot shop, purify the back after filtration and discharge; Offer the large-area glass observation window on the sidewall of compartment, the easy access personnel are to the supervision of surrounding environment between maintenance object and valve-seating trimming, the daylighting between also being convenient to grind simultaneously.The utility model practicality height, for the maintenance personal provides convenience, the cost that has reduced the nuclear power station operation and safeguarded improves the quality of maintenance, and is safe.

Among the figure: 1 compartment; 2 compartments; 3 stainless steels open the door; 4 exhaust hoods; 5 holes for hoist; 6 filtering inlet air casees; 7 Airshower chambers; 8 capouch; 9 bellowss 10 filter the air draft case; 11 electric pushrods; 12 supports; 13 Cleaning luminaires; 14 windowpanes; 15 snap rings; 16 operating desks; 17 holding tanks.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
Floor space can be 12m * 5m between the valve-seating trimming that the utility model proposes, and the compartment height can be 3.5m.Main frame between the valve-seating trimming adopts 100 * 100 * 5mm square tube to be connected and composed by bolt, and around the compartment 1,2 and top can adopt color steel (interior folder resistance combustion polyurethane foam or filling rock wool) to constitute.Mounting plate can be placed in compartment 1,2 bottoms, and mounting plate and ground adopt M12 expansion foundation bolt to fix.
For fear of between valve-seating trimming between hot tool car in during assembled in situ may to original ground cause impaired, then adopt with ground epoxy coating identical between hot tool car compartment 1,2 bottoms repaired.
As depicted in figs. 1 and 2, two the steel construction compartments 1,2 that communicate have door on the sidewall that compartment 1,2 overlaps, and two compartments are communicated, and compartment 1 is opened and stainless steel is installed on sidewall is in addition opened the door 3 in addition.
As shown in Figure 3, place an inspection operation platform 16 in the compartment 1, but two oscilaltions are installed above operating desk 16, the dust suction exhaust hood 4 of move left and right, described exhaust hood 4, the capouch 8 that comprises a back taper, the telescopic bellows 9 that is communicated with it is installed on the capouch 8, be installed with the filtration air draft case 10 that communicates with it on the bellows 9, be connected with electric pushrod 11 on the described capouch 8, the upper end of electric pushrod 11 is connected on the hard-wired support 12, and this filters air draft case 10 and can be connected with the exhaust system of hot shop.
When the capouch 8 of electric pushrod 11 pulling exhaust hoods 4 moved, bellows 9 was flexible up and down, and gas filters by filtering air draft case 10, and the move left and right of exhaust hood 4 can adopt manual form.
In order to guarantee the ventilation between the valve-seating trimming, compartment 1 outer wall is provided with filtering inlet air case 6, but the filter of this filtering inlet air case 6 adopts GKF-5A inferior high efficiency filter, filter efficiency 〉=95% (for particle diameter 〉=0.5 μ m dust), initial resistance≤69Pa (690mmH
2O).
Because valve that must maintenance will move in hot shop, but so between valve-seating trimming the top offer the hole for hoist 5 of the folding of a 1m * 1m, the moving of convenient maintenance valve.
