Description

a flexible pipe

technical field

The utility model relates to a pipe fitting, in particular to a flexible pipe fitting.

Background technique

The current pipeline system is diverse and complicated. In actual installation, it is sometimes necessary to connect pipelines of different materials. For example, the welding connection realized by hot air welding technology has the problem of weak welding points. The use of cast iron metal pipe fittings as connecting pipe fittings is not only heavy, but also easy to corrode and rust for a long time, causing water leakage accidents. Metal pipe fittings need to be connected by mechanical flanges. There are a large number of bolts, and it is difficult to adjust the alignment of the flange screw holes on both sides. In addition, the radial corresponding bolts must be tightened synchronously, which is inconvenient to operate, especially due to changes in ambient temperature. And the connecting bolts will expand with heat and contract with cold, which will easily cause the bolts to loosen and cause leakage at the connection parts. Not only the flexibility is not good, but also the sealing performance is not guaranteed. A common flexible connection method in China is mainly realized by rubber sealing rings, which have strict requirements on matching dimensions, and are not suitable for quick changeover requirements, and are generally not suitable for connecting pipes of different materials. There are certain application fields. limitation.

Contents of the invention

The utility model makes up for the deficiencies in the existing connection technology, and provides a flexible pipe fitting with good deflection, wider application and quick connection.

The utility model provides a flexible pipe fitting, which comprises a pipe fitting main body and a metal ring with buckles. The metal ring is located at both ends of the pipe fitting main body. The buckle is a screw locking structure, including a locking screw and a throat hoop main body. , the tightening screw and throat hoop are made of stainless steel.

The main body of the pipe is made of elastic materials such as rubber or thermoplastic elastomer or alloy of rubber or PVC.

The main body of the pipe fitting is directly molded by injection molding.

The main body of the pipe fittings is in the form of straight through, elbow, different diameter, tee and other fittings.

Compared with the prior art, the utility model has the advantages of:

The flexible pipe itself has a certain bending performance and is easy to install. The free change in length can be used to compensate for the difference in horizontal and vertical distances. This product can connect pipes and joints of different materials, including plastic pipes, clay pipes, iron pipes, copper pipes, etc. The pipe fitting itself has considerable flexibility, and when the metal ring is fastened, it can produce good adhesion with the sealed pipe, and has strong anti-leakage ability. Compensate and absorb the axial, transverse and angular thermal deformation of the pipeline during thermal expansion and contraction, and can withstand high and low temperature changes. Absorb equipment vibration and reduce the impact of equipment vibration on pipelines. Absorb the deformation of the pipeline caused by earthquakes and ground subsidence.
