221 maximum spacing, enables vane 221 to be normally carried out rotation, and rotation approach is not limited by air scoop 234.
The working principle of the invention: pressing curved splint 215 makes 212 stress of inner spring and inside contracts, thus by clamping ring
211 sets are sealed against pushing away in blanking cover 2 on 1 outer wall of pipeline so that seal limitation of the blanking cover 2 by 1 nozzle of pipeline, pass through control
Hydraulic stem 210 is adsorbed on powerful electromagnetic chuck 216 tightly on the outer wall of pipeline 1, along with inner spring 212 is to curved splint
215 pressure can increase the friction with pipeline 1 because the antiskid particles 214a in arc clip pad 214 is coarse material, so that
Arc clip pad 214 can tightly clamp pipeline 1, to improve the installation stability and leakproofness of sealing blanking cover 2, seal after installation
Circle 204 can be tightly bonded with 1 inner wall of pipeline, ensure that the leakproofness of pipeline, and after sealing ring aging, leakproofness is deteriorated, and be made
The vapor evolution obtained on a small quantity comes out, and gas leakage prompting device can send out prompt, so that operator can repair in time, herein
Before, it is collected in steam by gas gathering mask 232, because gas gathering mask 232 is in bucket-shaped setting, be capable of larger area blocks steam
It effectively prevent steam to export from the gap of gas gathering mask 232 and 1 inner wall of pipeline, can be provided for the rotation of vane 221 biggish dynamic
Power, so that steam is exported along venthole 231, escape pipe 233 from air scoop 234, because of opening for gas-guide tube 233 and air scoop 234
Mouthful towards 221 mouthfuls of vane, so that steam is since inertia is exported to the opening direction of air scoop 234, to act on vane
221, vane 221 drives hollow rotating cylinder 220 in the guide and limit for playing guide groove 220a and guide ring 202 by lightweight connecting bar 222
It is rotated under effect, hollow rotating cylinder 220 then discharges clockwork spring 224 when rotating, so that clockwork spring 224 generates outside O-shaped elastic ring 223
Thrust, so the diameter of O-shaped elastic ring 223 become larger until by 1 inner wall of pipeline limitation and with 1 inner wall of pipeline fitting contact,
It can largely prevent steam outgoing.
In conclusion the technological progress that the present invention obtains compared with the prior art is: inhaling strength by controlling hydraulic stem
Disk is tightly adsorbed on the outer wall of pipeline, along with inner spring is to the pressure of curved splint, because of anti-skidding in arc clip pad
Grain is coarse material, can increase the friction with pipeline, arc clip pad is enabled tightly to clamp pipeline, to improve seal plug
The installation stability and leakproofness of lid block steam by what bucket-shaped gas gathering mask was capable of larger area, thus by the steaming of leakage
Vapour carries biggish power through escape pipe, air scoop for vane and hollow rotating cylinder is driven to be rotated, and then the characteristic based on clockwork spring,
O-shaped elastic ring and inner wall of the pipe are bonded to contact, can largely be prevented outside steam before repairing in maintenance man
Leakage avoids high-temperature steam from scalding operator, is also avoided that the generation of the perils such as explosion, and when maintenance man comes to repair passes through
The flexible i.e. quick release of control hydraulic stem repairs.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
