The closure in road, and in particular to the pipe pressurized closure tooling of one kind and method.
Background technique
At present in petrochemical plant upkeep operation, valves leakage is frequently encountered, needs to carry out replacement repairing to valve,
Full factory's parking is replaced and is repaired to valve when general overhaul, but in small-sized on-line maintenance, valves leakage can not be closed
It closes, progress can not be successfully to the maintenance of subsequent pipeline, at this moment need to block pipeline with pressure, convenient for the inspection of subsequent pipeline
It repairs.
Summary of the invention
The purpose of the present invention is to provide a kind of pipe pressurized closure tooling and methods, to solve problem of the prior art,
Through the invention closure is formed after condensing in sealant flow in pipes, to solve valves leakage, real problem is fitted badly.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of pipe pressurized closure tooling, including screw thread cylinder, hollow boring bit and injecting glue connector, screw thread cylinder setting in
Screw thread, external screw thread is arranged in hollow boring bit, and the external screw thread of the internal screw thread of screw thread cylinder and hollow boring bit is cooperatively connected, and core drill
Head can be rotationally advancing or retreat in screw thread cylinder, be provided with hole for injecting glue on one end in hollow boring bit insertion screw thread cylinder,
Hole for injecting glue is connected to the glue injection channel inside hollow boring bit, and one end of the other end connection glue injection connector of hollow boring bit, injecting glue connects
The other end of head is connected to glue injection machine by rubber injecting valve.
Further, the hollow boring bit includes hollow cylinder and the hollow cone for being connected to hollow cylinder one end, sky
One end of the other end connection glue injection connector of heart cylinder, hole for injecting glue are arranged on the arcwall face of hollow cone.
Further, external screw thread is arranged on hollow cylinder, and the other end of hollow cylinder is provided with internal thread hole, hollow
The other end of cylinder is connected by internal thread hole with the big end screw thread of injecting glue connector.
Further, the other end of injecting glue connector is connect by small end screw thread with rubber injecting valve.
Further, when in use, the free end of screw thread cylinder is sealedly connected on pressure pipeline outer wall.
Further, the sealed connection is specially and welds, and welding manner is to be fully welded.
Screw thread cylinder one end is polished into and the pressure pipeline outer wall energy to be blocked by a kind of pipe pressurized method for blocking first
The arc being enough bonded, then be fully welded in pressure pipeline outer wall, seal screw thread cylinder welding ends and pressure pipeline outer wall, then
Hollow boring bit is screwed in from the screw thread cylinder other end, when hollow boring bit touches pressure pipeline outer wall, by injecting glue connector big end
The tail portion of hollow boring bit is screwed in, and in injecting glue connector other end connection glue injection valve, rubber injecting valve is to close at this time, then proceedes to revolve
Into hollow boring bit, at this moment, hollow boring bit drilling pressure pipeline outer wall continues to creep into, until the hole for injecting glue on hollow boring bit enters
In pressure pipeline, at this time stop drilling, rubber injecting valve the other end install glue injection machine, open rubber injecting valve, indentation sealing glue, until
One section for filling up pressure pipeline blocks pressure pipeline after colloid condensation.
Compared with prior art, the invention has the following beneficial technical effects：
Present invention is mainly used for the interior leakage with pressure for solving the problems, such as petroleum and petrochemical industry factory pipeline, guarantee that petroleum and petrochemical industry device is not parking
Work, mainly temporarily solves the problems, such as that valves leakage fits badly on pressure pipeline, passes through matching for screw thread cylinder and hollow boring bit
It closes, is drilled using screw thread feeding in duct wall, then colloid out of hole for injecting glue flow in pipes, formed and blocked, the injecting glue envelope with pressure
Stifled tool structure is simple, stops without full factory, on the production of full factory without influence, reduces the cost of overhaul, easy to implement, easy to use.
Screw thread cylinder is fully welded in pipeline outer wall by the method for the present invention, seals thread barrel welding ends and pipeline outer wall, then will
Hollow boring bit from the screw thread cylinder other end screw in, when bit contact arrive pipeline outer wall when, by injecting glue connector big end screw-in core drill
The tail portion of head, and in injecting glue connector other end connection glue injection valve, rubber injecting valve is to close at this time, then proceedes to precession core drill
Head, at this moment, hollow boring bit creep into pipeline outer wall, continue to creep into, until the hole for injecting glue on drill bit enters in pipeline, stop boring at this time
Into, glue injection machine is installed on rubber injecting valve, opens rubber injecting valve, indentation sealing glue, until one section of pressure pipeline is filled up, colloid condensation
It is easy to operate afterwards by pipe plugging, it stops without full factory, full factory is produced without influence.

Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing：
Referring to Fig. 1 and Fig. 2, a kind of injecting glue with pressure blocks tooling, including screw thread cylinder 1, screw thread are internal screw thread, this internal screw thread
It is cooperatively connected with the external screw thread 2-2 of hollow boring bit 2, the internal thread hole 2-3 of 2 bottom of hollow boring bit and the big end spiral shell of injecting glue connector 3
Line connection, screw thread cylinder 1 are welded on pressure pipeline outer wall, and are to be fully welded after need to polishing, hollow boring bit 2 is opened at taper bit position
There are hole for injecting glue 2-1 and the glue injection channel of hollow boring bit 2 to be connected to, pressure tube wall is drilled through using screw thread feeding, utilizes thread seal
Guarantee that liquid does not outflow in pipeline, 3 small end screw thread of injecting glue connector needs connection glue injection valve.
It is that 1 one end of screw thread cylinder is polished into the arc that can be bonded with the pipeline outer wall to be blocked first that injecting glue, which blocks work,
Shape, then be fully welded in pipeline outer wall seals 1 welding ends of screw thread cylinder and pipeline outer wall, then by hollow boring bit 2 from thread barrel
1 other end of body screws in, and when hollow boring bit 2 touches pipeline outer wall, 3 big end of injecting glue connector is screwed in the tail portion of hollow boring bit 2,
And in 3 other end connection glue injection valve of injecting glue connector, rubber injecting valve is to close at this time, then proceedes to precession hollow boring bit 2, at this moment,
Hollow boring bit 2 creeps into pipeline outer wall, continues to creep into, until the hole for injecting glue 2-1 on hollow boring bit 2 enters in pipeline, stops at this time
Drilling installs glue injection machine in the other end for the rubber injecting valve that injecting glue connector 3 is installed, rubber injecting valve, indentation sealing glue is opened, until filling up
One section of pressure pipeline, by pipe plugging after colloid condensation.
