Abstract
The invention belongs to nuclear power station service technique fields, and in particular to one kind repairs experiment supporting device for WWER nuclear power unit spring loaded safety valve；The purpose of the present invention is designing a kind of maintenance experiment supporting device, the nuclear class safety valve support fixation problem of two kinds of Russia's productions is solved, elimination safety valve is existing when repairing verification to fall risk；Including fastening plates (1), crossbeam (2), support post (3) and bottom plate (4)；Wherein the bottom plate (4) schedules ground by expansion bolt, two support posts (3) and bottom plate (4) are welded, crossbeam (2) both ends are welded and fixed with column, are fastened fastening plates (1) using M10 bolt by the hole on crossbeam.
Description
Technical field
The invention belongs to nuclear power station service technique fields, and in particular to one kind is used for WWER nuclear power unit spring loaded safety valve
Repair experiment supporting device.
Background technique
In two WWER-1000/V-428 type nuclear reactor plants of field gulf nuclear power station first stage of the project, Russia is shared
The y Ф 53070-015 К of the supply of material, Ц К Б P53085-015 model 345, safety valve, these model safety valves are each
In unit refueling outage, comprehensive disassembling overhaul need to be carried out to part therein, all carries out pressure setting test, both models
Safety valve maintenance and pressure setting experiment when, can not be on existing battery of tests rack due to the reasons in structure of valve
Pressure setting is carried out, progress valve disintegration, maintenance and inspection and assembly on bench vice, including pressure setting test can only be clamped in,
Since valve mass is larger, there is bench vice sometimes and clamp unstable phenomenon, there are valves to fall risk, and due to safety valve
It is higher using compressed air pressure when verification, it is understood that there may be risk that valve falls or play is hurted sb.'s feelings, it is therefore desirable to design one kind
Experiment supporting device is repaired, the nuclear class safety valve of above two Russia's production is supported, eliminates safety valve maintenance verification
When existing risk.
Our autonomous Design processing and fabricatings are a kind of thus repairs experiment supporting device, main needle for spring loaded safety valve
Peace is fixedly mounted in the design feature of the y Ф 53070-015 К, Ц К Б P53085-015 model safety valve that supply to Russia
Full valve eliminates valve and clamps unstable phenomenon on bench vice, eliminates valve and falls risk, while eliminating since there are valves to fall
Or play is hurted sb.'s feelings risk.
Summary of the invention
The object of the present invention is to the y Ф 53070-015 К of Russia's supply of material, Ц К Б P53085-015 model safety
Valve need to carry out comprehensive disassembling overhaul to part therein, all carry out pressure setting test in each unit refueling outage,
The safety valve of both models, can not be existing complete due to the reasons in structure of valve in maintenance and pressure setting experiment
Pressure setting is carried out on test-bed, can only be clamped in progress valve disintegration, maintenance and inspection and assembly on bench vice, including pressure
There is bench vice sometimes and clamp unstable phenomenon in regulation experiment, there are valves to fall risk since valve mass is larger, and
It is higher using compressed air pressure when due to safety valve testing, it is understood that there may be risk that valve falls or play is hurted sb.'s feelings, therefore need
A kind of maintenance experiment supporting device is designed, the nuclear class safety valve for solving above two Russia's production supports fixation problem, disappears
Fall risk except existing when safety valve, which repairs, to be verified.
The technical scheme is that
One kind repairing experiment supporting device, including fastening plates, crossbeam, support for WWER nuclear power unit spring loaded safety valve
Column and bottom plate；Wherein the bottom plate schedules ground by expansion bolt, and two support posts and bottom plate weld, crossbeam both ends with
Column is welded and fixed, and is fastened fastening plates using M10 bolt by the hole on crossbeam.
The beneficial effects of the present invention are:
One kind is provided and repairs experiment supporting device for WWER nuclear power unit spring loaded safety valve, apparatus structure simply may be used
It leans on, use is simple and efficient, can stablize Russia's supply of material safety valve of installation different size model, provide maintenance and pressure for it
Regulation experiment platform, fixes it effectively, and risk of colliding with is fallen in elimination.
Detailed description of the invention
Fig. 1 is that a kind of WWER nuclear power unit spring loaded safety valve maintenance experiment supporting device that is used for provided by the present invention shows
It is intended to；
Fig. 2 is provided by the present invention a kind of for WWER nuclear power unit spring loaded safety valve maintenance experiment supporting device master
View；
Fig. 3 is provided by the present invention a kind of tight for WWER nuclear power unit spring loaded safety valve maintenance experiment supporting device
Solid plate structure chart；
Fig. 4 is provided by the present invention a kind of horizontal for WWER nuclear power unit spring loaded safety valve maintenance experiment supporting device
Girder construction figure；
Specific embodiment
The present invention is further introduced below with reference to embodiment:
As shown, provided by the present invention a kind of for WWER nuclear power unit spring loaded safety valve maintenance test support dress
It sets, including fastening plates 1 shown in Fig. 2, crossbeam 2, support post 3, bottom plate 4.Bottom plate is scheduled into ground using expansion bolt, support is vertical
Column and bottom plate weld, and crossbeam both ends are welded and fixed with column, will fasten version using M10 bolt by the hole on crossbeam and fasten, complete
At safety valve maintenance experimental rig installation.
Embodiment
[1], bottom plate is scheduled into ground using expansion bolt, version will be fastened using M10 bolt by the hole on crossbeam and fastened,
Complete safety valve maintenance experiment supporting device installation.
[2], the fastening plate hole of the support plate device on the safe valve body of y Ф 53070-015 К model is used just
Safety valve is installed on support device by safety valve support plate fastening bolt, carries out the maintenance and test of safety valve.
[3], the safe valve body of Ц К Б P53085-015 model and the fastening plate hole of the present apparatus are managed to just using DN80
Block the fastening plates across support device and fastened with nut, completes the fixed support of safety valve.
