Abstract
The invention relates to a spheroidal graphite cast iron two-flange single-spigot tee which has the advantages that the amount of used materials and the number of pipe interfaces can be reduced, the labor is greatly saved and the reliability and the safety factor of a firefighting system are enhanced. The spheroidal graphite cast iron two-flange single-spigot tee comprises a tee main body which is integrally molded by a first-way pipe, a second-way pipe and a third-way pipe, wherein the axis of the first-way pipe and the axis of the second-way pipe are on the same line, the axis of the third-way pipe is perpendicular to the axis of the first-way pipe or the second-way pipe, the nominal diameter of the third-way pipe is 65mm and is adaptive to the diameter of a tee on a fire hydrant system, the nominal diameter of the second-way pipe is 80mm, and a flange which is adaptive to an external valve is arranged at the end part of the second-way pipe. The spheroidal graphite cast iron two-flange single-spigot tee has the advantages that the flange spigots can be saved, DN80-to-DN65 special reducing threaded flanges, anti-falling devices, fixing supports and the like are also saved, the amount of the materials and the number of the pipe interfaces are reduced by adopting the installation method, the labor is greatly saved and the reliability and the safety factor of the firefighting system are enhanced.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of spheroidal graphite cast iron double plate list and insert threeway.
Background technique
According to subway operation experience for many years, adopting centrifugal ductile cast iron pipes at underground running tunnel is the good a kind of tubing that can tackle metro stray current corrosion.Therefore in " metro design code " and Practical Project Water And Drainage System Design, in running tunnel, fire protection pipeline need adopt socket joint centrifugal ductile cast iron pipes and pipe fitting.
, all there is the inside and outside reasons such as self quality of product, mounting technique, Environmental Conditions and replacing valve in any superior in quality pipeline material, pipe fitting or the valve etc. that need to break down to part overhaul and change.
Under normal circumstances, spheroidal graphite cast iron threeway main body 1 is dish, inserting structure or overall structure, shown in Fig. 1 and Fig. 2, caliber minimum is the threeway of DN80 × DN80, and what on general hydrant system, use is the threeway (DN80 mono-side flange must could connect DN65 fire hydrant after reducing) of DN150 × DN65.The threeway of this structure when for connections such as hydrant system 103, valves 102, need first on threeway bellmouth, install a joint dish and plug in short tube 101(and be commonly called as short tube second), connect again afterwards valve, dish holds the parts such as short tube (being commonly called as short tube first).While installation by such method, interface quantity is many, must establish the annexes such as fixed support at short tube jointing, for this reason, needs to consume a large amount of artificial and machinery expenses, also exists the many factors of the many both hidden danger of this special environmental interface in interval simultaneously.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one and can reduce material consumption and pipe connector quantity, also saved in a large number manually simultaneously, strengthen the reliability of fire-fighting system and the spheroidal graphite cast iron double plate list of safety coefficient and inserted threeway.
Spheroidal graphite cast iron double plate list of the present invention is inserted threeway, comprise by the first siphunculus, the second siphunculus and the integrated threeway main body of three-way pipe, the shaft axis of the shaft axis of described the first siphunculus and the second siphunculus is the same line, the shaft axis of described three-way pipe is perpendicular to the shaft axis of the first siphunculus or the second siphunculus, the nominal diameter of described three-way pipe is 65mm, suitable with the threeway on hydrant system, the nominal diameter of described the second siphunculus is 80mm, is provided with the flange plate suitable with external valve in the end of described the second siphunculus.
Further, described threeway main body is spheroidal graphite cast iron threeway main body.
By such scheme, the present invention carries out technological innovation on the basis of threeway, to hold, dish, the threeway of inserting structure is innovated into double plate list and is inserted threeway, minimum is manufactured to caliber DN80 improvement manufactures and designs the caliber (DN65) adapting simultaneously, manufacturing specification is the slotting threeway of spheroidal graphite cast iron double plate list of DN150X65, so not only can saving dish plug in short tube (being commonly called as short tube second) and also save DN80 simultaneously and become special reducing thread flange and anti-drop device and the fixed support etc. of DN65, and this mounting type has reduced material consumption and pipe connector quantity, also saved a large amount of artificial simultaneously, reliability and the safety coefficient of fire-fighting system are strengthened.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Shown in Fig. 3 and Fig. 4, a kind of spheroidal graphite cast iron double plate list is inserted threeway, comprise by the first siphunculus 11, the second siphunculus 12 and the integrated threeway main body 1 of three-way pipe 13, the shaft axis of the shaft axis of the first siphunculus 11 and the second siphunculus 12 is the same line, and the shaft axis of three-way pipe 13 is perpendicular to the shaft axis of the first siphunculus 11 or the second siphunculus 12.
The nominal diameter of three-way pipe 13 is 65mm, suitable with the threeway on hydrant system 103;
The nominal diameter of the second siphunculus 12 is 80mm, is provided with the flange plate 14 suitable with external valve 102 in the end of the second siphunculus.Threeway main body 1 is spheroidal graphite cast iron threeway main body.
The present invention carries out technological innovation on the basis of threeway, to hold, dish, the threeway of inserting structure is innovated into double plate list and is inserted threeway, minimum is manufactured to caliber DN80 improvement manufactures and designs the caliber (DN65) adapting simultaneously, manufacturing specification is the slotting threeway of spheroidal graphite cast iron double plate list of DN150X65, so not only can saving dish plug in short tube (being commonly called as short tube second) and also save DN80 simultaneously and become special reducing thread flange and anti-drop device and the fixed support etc. of DN65, and this mounting type has reduced material consumption and pipe connector quantity, also saved a large amount of artificial simultaneously, reliability and the safety coefficient of fire-fighting system are strengthened.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
