Embodiment

[0032] First, connect the cylinder body 11 to the pipe fittings of the pressure pipeline that needs to be blocked, seal the cylinder upper cover 12 with the cylinder body 11, and socket the universal ball 13 on the outer wall of the outer rod 3. The cylinder upper cover 12 has a half Circular groove, the universal ball gland 14 has a groove with the same size as the semicircular groove of the cylinder loam cake 12, the groove on the universal ball gland 14 is the same as the groove on the cylinder loam cake 12 When fastened, it just accommodates the universal ball 13, and a sealing ring is also provided at the joint between the universal ball 13 and the outer wall of the outer rod 3, and the sealing ring is used to seal the joint between the adapter device and the outer rod to prevent leakage of the fluid medium. Cover the universal ball 13 with the ball gland 14 on the upper cover 12 of the cylinder; hold the outer rod 3 to lower the sealing device into the pressure pipe, push...

Abstract

The invention discloses a plugging device which comprises an adapter device, a drive device and a plugging device body; the adapter device is used for being in adaptive connection with special pipe fittings of various pipes; the drive device comprises an outer rod and an inner rod, the outer rod penetrates through the upper end of the adapter device and is connected with a plugging shell in a threaded mode, the lower portion of the inner rod is provided with an outer thread which can drive a wedge-shaped sliding block of the plugging device body to move up and down in the plugging device body, movement of the wedge-shaped sliding block can push a first compression conical plate and a second compression conical plate to inwards squeeze an elastic plugging ring, and the purpose of sealing a pipe through the elastic plugging ring is achieved. By means of the plugging device, the technical defects that in the prior art, a plugging device is complex in structure, complex to operate and not ideal in plugging effect, and excessively large rotary twisting force is needed for operation are well overcome.

Description

technical field [0001] The invention relates to a occluder, in particular to a occluder used to block the medium in the upstream pipeline when repairing and maintaining various pipelines with pressure and replacing valves in the pipeline. Background technique [0002] In various pressurized pipeline engineering operations such as modern oil and gas transmission, pipeline transmission, distribution, maintenance and rush repair work is an important basic link. With the continuous progress of urban development, various pipeline projects under pressure have become very frequent; in In the transmission and distribution pipeline system, pressure valves are important components of this type of pipeline transmission and distribution system; however, the above-mentioned pressure valves will inevitably have aging or corrosion problems after long-term use or in an acid-base environment, which may cause leakage of the pressure valve. Not only does it affect the use, but once the medium ...
