Technical Field

The invention relates to the technical field of pipe plugs, in particular to a pipe plug capable of preventing fragmentation.

Background

A heat exchanger for condensing the exhausted steam of steam turbine into water is also called as a water re-heater. The condenser is mainly used in a steam turbine power device and is divided into a water-cooling condenser and an air-cooling condenser. The condenser can condense the exhaust steam of the steam turbine into water for reuse by a boiler, and can establish vacuum and maintain vacuum at the exhaust steam part of the steam turbine, generally, a cooling pipe is arranged in the condenser, the cooling pipe is formed by a bent metal pipe and is arranged in liquid and is an important part of power equipment, the temperature of waste gas generated by the work of a power system can be reduced through the cooling pipe, the waste gas can be divided into metal and plastic, and the condenser is suitable for machine tools, hydraulic machinery, numerical control machine tool working oil and water cooling system.

However, most pipe plugs in the market have single functionality and are inconvenient to use, and when the traditional pipe plug is used, the outer pipe plug is obviously damaged and is broken at multiple positions, so that the plugging effect of the pipe plug is influenced, and the service life of the pipe plug is also shortened.

Disclosure of Invention

The present invention is directed to a pipe plug capable of preventing fracture, so as to solve the problems mentioned in the background art.

In order to achieve the purpose, the invention provides the following technical scheme: a frac-resistant plug comprising:

an outer tube plug;

an inner pipe plug;

the plastic plug comprises an end cover, grooves are formed in two sides of the outer wall of the end cover, stand columns are fixedly arranged on the surfaces of the inner walls of the two grooves, an outer cap is fixedly connected to one end of each stand column, and through holes are formed in the stand columns and the inner portion of the outer cap;

the inner pipe plug is inserted into the outer pipe plug, and the plastic plug is inserted into the port of the inner pipe plug.

Preferably, the outer pipe plug includes a body, fretwork portion has been seted up to a body one end, No. one the outer edge of detaining of body other end fixedly connected with.

Preferably, the inner pipe plug comprises a second pipe body, one end of the second pipe body is fixedly connected with the pipe bottom, and the other end of the second pipe body is fixedly connected with a second outer buckling edge.

Preferably, the surface of the end cover is provided with a pump body hole close to the axis.

Preferably, No. one body and No. one outer knot are followed as integrated into one piece structure.

Preferably, No. two body and No. two outer edges of detaining are the integrated into one piece structure.

Preferably, the upright post and the outer cap are of an integrally formed structure.

Preferably, the outer tube plug is made of a PP material.

Preferably, the inner pipe plug is made of PPS material.

Compared with the prior art, the invention has the beneficial effects that:

1. the outer pipe plug is made of PP materials, so that the outer pipe plug is good in bending fatigue resistance, very stable in chemical performance, resistant to seawater erosion and free of electrochemical corrosion, is not easy to break in the using process, and can effectively prolong the service life of the outer pipe plug.
