Description
Technical field
The present invention relates to threeway technical field, more particularly to a kind of easy-to-maintain threeway.
Background technology
Currently marketed three-port structure, usually main siphunculus with bypass pipe by welding or being integrally formed, this three
Logical good sealing effect, the possibility of threeway junction leak gas leakage are smaller.But because threeway junction is mostly propped up in pipeline
The intersection of line and main line, when as drainpipe, often block herein, or the maintenance after blocking cuts open threeway
Cleaning can just be overhauled by unloading the very long segment pipe being connected with threeway, and workload is big, and inspection speed is slow.
The content of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, there is provided a kind of easy-to-maintain threeway, including main siphunculus 1 and bypass pipe 2,
The outer wall of main siphunculus 1 is provided with opening 3, and opening 3 is provided with boss 4, and one end of boss 4 is bonded with the outer wall of main siphunculus 1, convex
The other end of platform 4 is plane, and boss 4 and main siphunculus 1 are structure as a whole, and the end face of the boss 4 is provided with through hole 5, and through hole 5 passes through
Wear boss 4 and opening 3 connect, the inner surface of through hole 5 is provided with internal thread 51, the outer wall of one end of the bypass pipe 2 be provided with it is interior
The external screw thread 21 that screw thread 51 is engaged, hex nut 6 is also arranged with the tube wall of bypass pipe 2, and hex nut 6 is solid with bypass pipe 2
Fixed connection.
Preferably, teflin tape 7 is wound outside the external screw thread 21.
Preferably, the threeway also includes elastomeric pad 8, and the elastomeric pad 8 is located at the planar end surface and bypass pipe of boss 4
Between hex nut 6 on 2.
The beneficial effects of the invention are as follows：In scheme provided by the present invention, main siphunculus and the bypass pipe of threeway pass through screw thread
Coordinate, teflin tape and elastomeric pad realize quick connection, while ensure sealing effectiveness, in addition, six on bypass pipe
Angle nut provides the position of card spanner when removing and installing, and both easy disassembly, protects three-way tube wall not damaged by spanner again, this hair
Bright provided threeway dismounting is quick, and maintenance is convenient and strength-saving, is adapted to promote.
Brief description of the drawings

As shown in Figure 1 and Figure 2, the present invention is a kind of easy-to-maintain threeway, including main siphunculus 1 and bypass pipe 2, the master are led to
The outer wall of pipe 1 is provided with opening 3, and opening 3 is provided with boss 4, and one end of boss 4 is bonded with the outer wall of main siphunculus 1, boss 4 it is another
One end is plane, and boss 4 and main siphunculus 1 are structure as a whole, and the end face of the boss 4 is provided with through hole 5, and through hole 5 runs through boss 4
Connected with opening 3, the inner surface of through hole 5 is provided with internal thread 51, and the outer wall of one end of the bypass pipe 2 is provided with and the phase of internal thread 51
The external screw thread 21 of cooperation, hex nut 6 is also arranged with the tube wall of bypass pipe 2, hex nut 6 is fixedly connected with bypass pipe 2.
Teflin tape 7 is wound outside the external screw thread 21.
The threeway also includes elastomeric pad 8, and the elastomeric pad 8 is located at the planar end surface of boss 4 and six on bypass pipe 2
Between angle nut 6.
In scheme provided by the present invention, the main siphunculus of threeway is coordinated with bypass pipe by screw thread, teflin tape and
Elastomeric pad realizes quick connection, while ensures sealing effectiveness, in addition, the hex nut on bypass pipe is provided when removing and installing
The position of card spanner, both easy disassembly, protects three-way tube wall not damaged by spanner again, and threeway dismounting provided by the present invention is fast
Speed, maintenance is convenient and strength-saving, is adapted to promote.
Above-mentioned according to the present invention is enlightenment, by above-mentioned description, relevant staff completely can without departing from
In the range of this invention technological thought, various changes and amendments are carried out.The technical scope of this invention is not limited to
In the content on specification, it is necessary to determine its technical scope according to right.
