Lost-foam pipe saddle

Abstract

The invention relates to a rapid pipeline water intake facility, in particular to a lost-foam pipe saddle which is provided with a pipe saddle substrate characterized by comprising mutually matched first semicircular pipe saddle unit and second semicircular pipe saddle unit. The first semicircular pipe saddle unit is provided with an outer pipe connecting opening, a first semicircular pipe saddle outer surface and a first semicircular pipe saddle inner surface which are penetrated by the outer pipe connecting opening; the second semicircular pipe saddle unit is provided with a second semicircular pipe saddle outer surface and a second semicircular pipe saddle inner surface; both ends of the first semicircular pipe saddle unit are provided with connecting structures; both ends of the second semicircular pipe saddle unit are provided with connecting structures; the connecting structure at one end of the first semicircular pipe saddle unit is matched with the connecting structure at one end of the second semicircular pipe saddle unit; and the connecting structure at the other end of the first semicircular pipe saddle unit is matched with the connecting structure at the other end of the second semicircular pipe saddle unit.

Description

technical field [0001] The invention relates to a pipeline fast water intake device, in particular to a lost foam pipe saddle. Background technique [0002] The existing urban water supply, water transmission and distribution pipelines basically use ductile iron pipe fittings. Due to the characteristics of wear resistance, high temperature resistance, high strength, high elongation, and corrosion resistance, ductile iron pipe fittings have a long service life and are widely used. Due to its excellent performance, ductile iron can sometimes replace expensive cast steel and forged steel in use, which greatly reduces production costs. The existing pipe saddles are accessories that open holes in the pipes to take water directly in case of need of water source or emergency. The existing pipe saddles are all made of steel, the production cost is high and the service life cannot match the service life of the ductile pipe fittings. For example, Chinese Utility Model Patent No. ZL01...

Problems solved by technology

[0003] However, if the existing pipe saddles are directly connected to ductile iron pipe fittings for water intake, there will be a huge gap at the connection between the upper and lower pipe saddles, and the wall of the water intake pipe in the gap cannot be strengthened, but will be squeezed when the upper and lower pipe saddles are connected to each other. Even if the U-shaped connector is used, the contact surface between the U-shaped connector and the wall of the water-intake pipe is too narrow, so the pressure between the U-shaped connector and the wall of the water-intake pipe will easily exceed the standard after the fixed connection (pipe The tighter the saddle is connected to the water intake pipe, the greater the pressure between the U-shaped connector and the water intake pipe), which may damage the structure of the water intake pipe and cause an accident

In addition, the existing pipe saddle can only be connected to other pipes through valves, which has a narrow scope of application and is not conducive to the extension of pipes. The increase in water intake ports also means that there is redundancy in valve management.
