Raw, during relocating in the municipal administration being related in current municipal pipeline engineering and rushing to repair, backend user is used in order to reduce
Adverse effect, it is often necessary to which non-stop plugging operation is implemented to operating pipeline.Typically in the upstream and downstream position of maintenance pipeline
Plugging hole is opened up, block head is placed in pipeline and is blocked, set up while bypass line makes it possible to normally use
Row maintenance is changed, and the design of the block head in plugging device directly affects the quality of closure quality, should ensure the sealing for blocking
Effect, will also consider to block the destructiveness to pipeline.Block head typically requires that plugging effect is good, easily installs and dismantles, energy
Enough high efficiency requirements that reuses, meet site operation.
Content of the invention
Present invention address that the application demand to duct closing type device, and a kind of duct closing type device is provided.
