Specific embodiment
Embodiments of the invention are described in further detail below in conjunction with accompanying drawing.
Embodiment 1:When dangerous matter sources medium pipeline needs to carry out port closure or water conservancy diversion treatment, blocking component is entered first
Luggage is as follows with detailed process:Assembling self-locking drop-proof locking ring device, the first semicircle fixture 6 is passed through with the second semicircle fixture 11
The connection of hinge 7 forms complete circumferential channel fixture, i.e. friction self-locking component 3;Pulling force screw rod 4 is installed into branch by pulling force screw rod
The mounting hole of frame 5 is installed such as Fig. 3, composition self-locking drop-proof locking ring device.Seal assembly 1 is assembled by ring-shaped gasbag 13(Altogether
Three)Once mounting constitutes seal assembly in steel shell.Overall package, three length are passed through by friction self-locking component 3
Different pulling force screw rods 4 and pull-rod nut 8 are connected with the mounting flange 15 of seal assembly 1.Will extension flange 12 with it is corresponding
Conduction pipe and valve are connected, and make it have the function of water conservancy diversion and closure.
(1)Water conservancy diversion operating mode one:The implementation steps when fluid media (medium) pipeline occurring and needing to flow backwards treatment:Three are opened respectively
Friction self-locking component 2(It is connected by hinge 7 with the second semicircle fixture 11 by the first semicircle fixture 6 and is formed)By the first semicircle card
Adpting flange 10 on the semicircle fixture 11 of tool 6 and second is fixed on the outer tube wall near the fracture pipeline mouth of pipe using bolt 9
On, the single unit system that will have previously installed is arranged on to be needed at the mouth of pipe of pipeline of water conservancy diversion;Make three rings of seal assembly 1
Shape air bag 13 can be fully contacted after inflating with outer tube wall.Three ring-shaped gasbags 13 are inflated successively by compressor, makes it
Pipeline outer wall is held tightly in gas pressure expansion realize sealing(In the annulus that pipeline outer wall and seal assembly 1 may be constructed
Form throttling cavity and adapt to pressure pipe plugging higher), now pressure hydraulic medium higher by with extension flange 12 connect
The conduction pipe for connecing implements water conservancy diversion treatment.
(2)Water conservancy diversion operating mode two:The step of when fluid media (medium) pipeline occurring and needing closure treatment:Device installation process with lead
Stream operating mode is identical, the difference is that what is connected on extension flange 12 is blind plate or valve and pipeline.When for blind plate, directly will
Three ring-shaped gasbags 13 are inflated successively by Compressor Pipes, it is held pipeline outer wall tightly in gas pressure expansion and are realized sealing envelope
It is stifled to complete.When extend flange 12 connection be valve and conduction pipe when;Valve is opened first is installed(Device is installed
Process is identical with water conservancy diversion operating mode substantially reduce the fluid resistance of equipment installation especially the fast fluid of flow velocity in flow process
Installation), then three ring-shaped gasbags 13 are inflated successively by Compressor Pipes, it is held pipeline tightly in gas pressure expansion
Outer wall realizes sealing, and now pressure hydraulic medium higher is implemented at water conservancy diversion by the conduction pipe being connected with extension flange 12
Reason.Finally valve slowly closing is realized to block.
Present apparatus installation rate is fast, can human error of the fluid medium pipeline in natural calamity or work progress cause
Fracture situation, carrying out emergent closure or water conservancy diversion treatment prevents medium large area from revealing.Using combination ring-type friction self-locking
Blocking component 1 is installed the open-ended place of fixed -piping by mechanism 3, be will not fall off during pressure pipe plugging higher, peace
It is complete reliable.Blocking component 1 is held tightly pipeline using the pressure bladder 13 of its internal multilayer, and in pipeline outer wall and seal assembly 1
Throttling cavity is formed in the annulus that may be constructed and adapts to pressure pipe plugging higher;Shell end is provided with standard flange expansion
Exhibition interface 12, is connected with valve or conduction pipe and the fluid inside pipeline is blocked or water conservancy diversion.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention should be regarded as protection of the invention
Scope.
