Description
Technical field
The invention belongs to technical field of mechanical design, and in particular to a kind of nuclear power station-service flashboard clamping device.
Background technique
Parallel gate valve Parallel slide valve largely uses in nuclear power plant, especially applies in heavy caliber, high temperature, high-pressure system field, is core
Power plant is most common, is also the most valve arrangement of quantity, two WWER-1000/V-428 types of nuclear power station first stage of the project in field gulf
It is also widely used in nuclear reactor plant, the shared a pair of the flashboard of Parallel gate valve Parallel slide valve, " back-to-back " fits together, back side peace
Equipped with spring, since spring has carried out precommpression during installation, the elastic force of generation struts two sides flashboard to valve seat direction, makes lock
Plate and valve seat form pressing force in the initial stage, and this design can guarantee Parallel gate valve Parallel slide valve in system no pressure or low-pressure
State lower flashboard and valve seat form certain sealing force, improve low pressure seal performance, while being also possible to prevent flashboard and acting
It is fallen in journey.Parallel gate valve Parallel slide valve structure is as shown in Figure 1.
It is to deposit when dismantling flashboard assembly since its back side spring has carried out precommpression to Parallel gate valve Parallel slide valve during installation
In certain technical problem and risk is repaired, according to drawing it can be seen that the pre-compression force that spring generates is by valve seat and lock
The counterforce counteraction of plate, such flashboard athleticism in valve chamber keeps balance.But when carrying out valve detachable maintaining,
It needs to take out flashboard from valve chamber, when the moment reaction force that flashboard and valve seat disengage disappears, flashboard at this moment is in injustice
Weighing apparatus state, spring may eject flashboard, and flashboard, which has, collapses danger of blowing in；Separately when flashboard returns dress, need to carry out precommpression to spring,
So that two sides flashboard thickness is adjusted to certain value can just be installed in valve seat gap.
Based on the practical problem encountered is repaired above, a kind of flashboard clamping device is invented, when valve disassembly and assembly can be right
Flashboard carry out in advance clamp to offset spring force, this device first is that when flashboard be detached from valve seat when prevent flashboard from collapsing out, play guarantor
Protect gate sealing surface effect；Second is that can control the decrement of spring, i.e. control flashboard thickness is kept away when installing or taking out flashboard
Exempt from gate sealing surface and sealing surface of seat friction.
Summary of the invention
Present invention solves the technical problem that:
The present invention provides a kind of nuclear power station-service flashboard clamping device, and feature has: structure is compact to design, easy to operate, stable
Reliably；It can effectively solve the technical problem of flashboard installation, the disassembly of Parallel gate valve Parallel slide valve.
The technical solution adopted by the present invention:
A kind of nuclear power station-service flashboard clamping device, including support arm, spiral arm one, additional arm, pin, distance rod, handle, rotation
Arm two, jack, hinge.
One end that the spiral arm two is mounted on support arm is vertical, and distance rod runs through the other end of support arm, and both ends are distinguished
It is connect with handle, jack.
Described universal the same side for peaking at spiral arm two and being in support arm.
Hinge is mounted on the middle position of support arm by pin, and spiral arm one, additional arm are equipped on hinge.
The spiral arm one is parallel with spiral arm two, and additional arm is parallel with support arm, jack and additional arm contact.
The hinge can be rotated around pin.
When dismantling parallel gate plate, flashboard is promoted to certain altitude, but valve seat cannot be completely disengaged, otherwise flashboard, which has, collapses
It blows in danger；Flashboard clamping device is installed, notices that fixture contact should be clipped in the centre of flashboard；Maintenance personal's rotating handle, makes
Push rod compresses additional arm, and then pushes spiral arm, and spiral arm is made to compress flashboard；Flashboard backside springs are compressed to flashboard to take off with valve seat
It opens, then flashboard is carefully sling out of valve chamber；When flashboard returns dress, executed according to above-mentioned same method.
Beneficial effects of the present invention:
