Abstract
The invention discloses a conversion connecting device produced by adopting low-temperature ductile cast iron. A body of the connecting device is formed by overlapping a large disk and a small disk, wherein a conical round hole is formed in the central position of the large disk; a cylindrical round hole is formed in the central position of the small disk; the diameter of the cylindrical round hole is identical with that of a small section round hole of the conical round hole; bolt holes are formed on the periphery of the large disk; screw holes are formed on the periphery of the small disk; and a conical angle of an inner cone of the large disk is 60 degrees. The reducing pipe is produced by adopting the ductile cast iron with high quality, high strength, high toughness and low temperature resistance, so that the quality of the reducing pipe is greatly improved, the service life of the reducing pipe is prolonged by over 20 times compared with that of an original reducing pipe, the weight of the reducing pipe is 1/4 of that of the original reducing pipe and the reducing pipe can be used in an environment with a temperature of -40DEG C. Due to small size and reduced weight, the reducing pipe is very convenient to mount in a time-and-labor saving way.
Description
Technical field:
The present invention relates to a kind of conversion connection set that adopts low temperature spheroidal graphite cast iron to produce, this connection set is mainly used in the middle of various oil transport pipelines, water supply line, the steam line, uses better effects if under low-temperature condition.
Background technique:
In the fluid line field, connection set is valve and pipe coupling a kind of connecting body commonly used, uses comparatively generally; Generally all be to adopt the CONCENTRIC REDUCER connection set to connect; The body of this connection set is long, volume is big, Heavy Weight, and structure is heavy, and is more loaded down with trivial details when connection is installed; Can not realize quick connection, and pass through time effort.In addition, enterprise is in producing the connection set process, and the rapid wear scrappage is high, makes cost of production increase.Use is at the low temperature severe cold areas, and connection set bursts apart especially easily, causes leakage of oil, leaks, gas leak phenomenon often has generation.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, connect the conversion connection set that quick, low temperature resistant high and cold employing low temperature spheroidal graphite cast iron is produced.
Technological scheme
The object of the invention is realized through following technological scheme; The body of this conversion connection set is to be made up of big disk and roundel stack, and the central position of big disk has the cone circular hole, and the central position of roundel has the cylindrical body circular hole; The radius of this cylindrical body circular hole is identical with the small bore circle hole radius of cone circular hole; Have bolt hole around the edge of big disk, have screw around the roundel, the cone angle of big disk female cone body is 60 °.
The present invention adopts the material of high-quality high tenacity, high tenacity, low temperature resistant spheroidal graphite cast iron to produce this conversion connection set; Quality of product is improved greatly; Improve 20 times or more than original connection set spare working life, and weight is 1/4 of former connection set spare, can under subzero 40 ℃ environment, use.Because volume reduces, weight saving, connection set installs more convenient, saves time, the saving of labor.

Embodiment
The present invention combines accompanying drawing that this connection set is done further to describe in detail; As can beappreciated from fig. 1; The body of this conversion connection set is that 2 stacks constitute with roundel by big disk 1, and the central position of big disk 1 has cone circular hole 3, and the central position of roundel has cylindrical body circular hole 4; The radius of this cylindrical body circular hole is identical with the small bore circle hole radius of cone circular hole; Have bolt hole 5 around the edge of big disk, have screw 6 around the roundel, the cone angle of big disk female cone body is 60 °.
The mouth of pipe of intake pipe 7 is communicated with through bolt with heavy in section circular hole of big disk on Fig. 2, and the centre is lined with seal ring; Circular hole on the roundel communicates with outlet pipe 8, and the centre is lined with seal ring, also is through bolton.
