Abstract
A kind of pipeline maintenance stifled threeway of inner blocking type plug, it is related to a kind of pipeline maintenance device, it includes at the pore of threeway (1) top configured with plug stifled (2), jam plate (3), drive ring (4), connecting rod (5), guide sleeve (6), copper sheathing (7), pin shaft (8), sealing ring (9) that the inner blocking type plug, which blocks up threeway,；It is formed with annular recess at the pore of threeway (1) top, matching therewith is jam plate (3), and the lower part of jam plate (3) has been bolted, and plug is stifled (2), and plug stifled (2) installs jam plate (3) and guide sleeve (6) above；The top of jam plate (3) connects connecting rod (5), and jam plate (3) installs copper sheathing (7) and connecting rod (5) above；Three connecting rods (5) install drive ring (4) and pin shaft (8) above；Connecting rod (5) is through pin shaft (8) and flanged joint；By the integral installation after above-mentioned assembly threeway (1) inside.The utility model can use for a long time, and high-pressure oil gas will not be leaked by lock ring hole, great to oil transportation, gas pipeline security implications.
Description
Technical field
The utility model relates to a kind of pipeline maintenance devices, more particularly to a kind of pipeline maintenance inner blocking type plug stifled three
It is logical.
Background technique
When tieing up repairing, existing prevailing technology includes aperture operation and closure operation for oil transportation, gas pipeline.Be first
Then welding tee on pipeline successively installs the equipment such as sandwich valve, aperture header, tapping machine and carries out aperture operation.Aperture operation
After the completion, successively the equipment such as installation closure header, plugging device, plug carry out closure operation on sandwich valve；Use of being honored as a queen is removed to open
Hole machine carries out decentralization and fills in stifled operation.
Conventional plug is stifled, threeway retaining mechanism principle is: having several lock ring holes, lock ring hole at the flange excircle of threeway
Interior hold-down hook nut, one end of hook nut are connect with lock ring, and the other end is in outside, by tool rotary hook nut, realize lock
Ring stretches, and when lock ring enters the stifled groove of plug, plug is stifled to be fixed on inside threeway.There is leakage in above-mentioned locking principle
Hidden danger, i.e., after long-time seal failure, high-pressure oil gas can be leaked by lock ring hole, cause security risk to oil transportation, gas pipeline.
So a kind of threeway of not lock ring hole, and it can be realized the stifled device of locking plug and be very important.
Summary of the invention
The purpose of this utility model is to provide a kind of pipeline maintenance inner blocking type plugs to block up threeway, the utility model jam plate
Lower part has been bolted, and plug is stifled, and plug blocks face installation jam plate and guide sleeve；Drive ring and pin shaft are installed above three connecting rods.
Aim at that on-line production pipeline plug for using when tieing up repairing is stifled, three-way device, the plug is stifled, the threeway existing threeway lock ring hole of solution is deposited
The problem of leaking hidden danger.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pipeline maintenance stifled threeway of inner blocking type plug, it includes configuring at the pore of threeway top that the inner blocking type plug, which blocks up threeway,
There is plug to block up, jam plate, drive ring, connecting rod, guide sleeve, copper sheathing, pin shaft, sealing ring；It is formed with annular recess at 1 top pore of threeway,
Matching therewith is jam plate, and the lower part of jam plate has been bolted, and plug is stifled, and plug blocks face installation jam plate and guide sleeve；Jam plate
Top connects connecting rod, installs copper sheathing and connecting rod above jam plate；Drive ring and pin shaft are installed above three connecting rods；Connecting rod is through pin shaft
With flanged joint；By the integral installation after above-mentioned assembly in the inside of threeway.
A kind of pipeline maintenance blocks up threeway with inner blocking type plug, and installation sealing ring is that plug blocks up and three at the stifled groove of plug
Sealing ring is equipped at logical top pore cooperation.
A kind of pipeline maintenance blocks up threeway with inner blocking type plug, and the inside of the threeway is at the pore of threeway top.
The advantages of the utility model, is with effect:
The utility model avoids live aperture operation and blocks, welds on pipeline in oil transportation, gas pipeline dimension repairing
It connects the equipment such as threeway and carries out closure operation；It also avoids that conventional plug is stifled, in flange excircle several lock ring holes are arranged in threeway, leads to
Cross the hidden danger of this leakage of tool rotary hook nut.The inner blocking type plug for specially devising not lock ring hole blocks up threeway, this is practical new
Type realizes that the structure setting of locking plug is very important by outer operation.It can use for a long time, high-pressure oil gas will not pass through
Lock ring hole leakage, it is great to oil transportation, gas pipeline security implications.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the left view of the utility model.
Component in figure: stifled 2, jam plate 3, drive ring 4, connecting rod 5, guide sleeve 6, copper sheathing 7, pin shaft 8, sealing ring 9 are filled in threeway 1.
Specific embodiment
The utility model is described in detail in illustrated embodiment with reference to the accompanying drawing.
At 1 top pore of threeway configured with plug stifled 2, jam plate 3, drive ring 4, connecting rod 5, guide sleeve 6, copper sheathing 7, pin shaft 8, close
Seal 9；It is formed with annular recess at 1 top pore of threeway, matching therewith is jam plate 3, and the lower part of jam plate 3 is through being bolted plug
Stifled 2, plug stifled 2 installs jam plate 3 and guide sleeve 6 above；The top of jam plate 3 connects connecting rod 5, and jam plate 3 is installed copper sheathing 7 above and connected
Bar 5；Three connecting rods 5 install drive ring 4 and pin shaft 8 above；Sealing ring 9 is installed at stifled 2 grooves of plug, that is, on plug stifled 2 and threeway 1
Sealing ring 9 is equipped at portion's pore cooperation；Connecting rod 5 is through pin shaft 8 and flanged joint；By the integral installation after above-mentioned assembly in threeway 1
Inside, that is, at 1 top pore of threeway.
The utility model plug is stifled, three-way device working principle: jam plate and plug it is stifled between connected by guide sleeve and screw,
The sliding in the radial direction that jam plate can be blocked up in plug.It, can be with by three link mechanisms when applying certain torque to drive ring
Move three pieces of jam plates to the stifled radial direction of plug along guide sleeve.When guide plate is completely into the groove for arriving threeway, plug is stifled
It is locked in inside threeway.Plug is stifled to install sealing ring between threeway internal diameter, and sealing ring plays sealing function, and jam plate plays receiving pressure
The effect of power.
