Description

Small-bore harmless pipe plug
Technical field
The utility model relates to pipe stopper field, is specifically related to a kind of small-bore harmless pipe plug.
Background technique
At present, pipe plugging technology is full-fledged, and using effect is also admitted.Domestic used pipe plugging is substantially all flange plugging structure, needs welding flange before pipe plugging, and welding job amount is large, and cost is high.
Summary of the invention
The purpose of this utility model is: provide a kind of small-bore harmless pipe plug, without welding flange, facilitate in-site installation, reduce installation period,
Pipeline is not destroyed, reduce costs, reduce installation difficulty.
Technical solution of the present utility model is: this small-bore harmless pipe plug comprises puller bolt, seal ring, gas injection joint, sealing seat, sealing bolt, sealed pressing sleeve and end cap, seal ring and sealed pressing sleeve load in sealing seat, sealing seat connects end cap by sealing bolt, puller bolt is arranged in the reserved tapped hole of end cap, the center of end cap is installed gas injection joint and connects sealing seat, the small-bore harmless pipe plug of overall formation.
The utility model has the following advantages: 1, adopt seal ring and sealing seat to coordinate, and carries out extruding and makes it expand, thus realize reliable sealing by tightening up sealing bolt to Sealing; 2, the utility model adopts the pressure of end cap puller bolt, clamping outer diameter tube and Sealing expansive force, and two gravity structure is the stuck pipeline of pipe plug, improves pipe plug Security greatly; 3, structure is simple, and easy for installation, operational torque is little, and installing at the scene does not need special tool, only needs spanner to complete installation and removal; 4, use this small-bore harmless pipe plug can effectively reduce operator's working strength, reduce the technical requirements of maintenance man and engineers and technicians, reduce cost of production, improve the performance of enterprises.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 puller bolt, 2 pipeline bodies, 3 seal rings, 4 gas injection joints, 5 sealing seats, 6 sealing bolts, 7 sealed pressing sleeves, 8 end caps.
Embodiment
As shown in Figure 1, this small-bore harmless pipe plug comprises puller bolt 1, seal ring 3, gas injection joint 4, sealing seat 5, sealing bolt 6, sealed pressing sleeve 7 and end cap 8, seal ring 3 and sealed pressing sleeve 7 load in sealing seat 5, sealing seat 5 connects end cap 8 by sealing bolt 6, puller bolt 1 is arranged in the reserved tapped hole of end cap 8, the center of end cap 8 is installed gas injection joint 4 and connects sealing seat 5, the small-bore harmless pipe plug of overall formation.
During installation, this harmless pipe plug, by reserved interior external series gap Inserting Tube road body 2, realizes seal for pipe joints and connection; Clamp pipeline outer wall by the puller bolt 1 on end cap 8, realize the connection of harmless pipe plug and pipeline; By tightening up sealing bolt 6, compresses seal 3 realizes the sealing of harmless pipe plug and pipeline.
