Pump And Valve Casting Part How To Distinguish Between Pump And Valve Castings And Forged Valves

Pump And Valve Casting Part How to distinguish between pump and valve casting and forging valve Casting valve is cast into the valve, the general cast valve pressure levels are relatively low (such as PN16, PN25, PN40, but also high pressure, can go to 1500Lb ,, 2500Lb), caliber Most of them are DN50 or more. Forging the valve is forged out, are generally used in the high level of the pipeline, the caliber is relatively small, generally below DN50.

  One, casting

  1, casting: that is, the metal smelting into a certain requirements of the liquid and poured into the mold, the cooling and solidification, the finishing process to get a predetermined shape, size and performance of the casting (parts or rough) process. Modern machinery manufacturing industry based on the process.

  2, casting production of low cost of rough, for the shape of complex, especially with complex cavity parts, can show its economy; at the same time it is more adaptable, and has a good overall mechanical properties.

  3, but the material needed for casting production (such as metal, wood, fuel, molding materials, etc.) and equipment (such as metallurgical furnace, sand mixer, molding machine, core machine, sand machine, shot blasting machine, cast iron plate ) More, and will produce dust, harmful gases and noise and pollute the environment.

  4, casting is a master of human earlier a metal thermal processing technology, has about 6,000 years of history. In 3200 BC, Mesopotamia appeared copper frog castings. Between 13 BC and 10 centuries BC, China has entered the heyday of bronze casting, the process has reached a very high level, such as the Shang Dynasty's weight of 875 kg of the mother of the East side of the tripod, the Warring States Zeng Houyi and the Western Han Dynasty Of the translucent mirror and so are the representative of the ancient casting products. Early casting by the impact of pottery, castings are mostly agricultural production, religion, life and other aspects of tools or appliances, art color thicker. In 513 BC, China cast out the world's first cast iron pieces written in the text - Jin Guicheng (about 270 kg weight). Before and after the 8th century, Europe began to produce cast iron pieces. After the 18th century industrial revolution, castings entered a new era of service for large industries. Into the 20th century, casting the development of fast, has developed a ductile iron, malleable cast iron, ultra-low carbon stainless steel and aluminum, aluminum, aluminum and magnesium alloy, titanium, nickel-based alloys and other cast metal materials, and invented the gray Cast iron for the new process of breeding. 50 years later, there have been wet sand high-pressure modeling, chemical hardening sand modeling and core, negative pressure modeling and other special casting, shot blasting and other new technology.

  5, casting a lot of types, according to the modeling method habits are divided into: ① ordinary sand casting, including wet sand type, dry sand and chemical hardening sand type 3. ② special casting, according to the modeling materials can be divided into natural mineral gravel as the main molding materials of special casting (such as investment casting, mud casting, casting workshop shell casting, negative pressure casting, solid casting, ceramic casting Etc.) and special casting materials (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) with metal as the main casting material.

  6, the casting process usually includes: ① mold (the liquid metal into a solid castings container) to prepare, according to the use of materials can be divided into sand type, metal type, ceramic type, mud type, graphite type, according to the number of times For the disposable, semi-permanent and permanent type, the preparation of the merits of the mold is the main factor affecting the quality of casting; ② casting metal melting and casting, casting metal (casting alloy) are cast iron, cast steel and casting nonferrous alloys; ③ Casting treatment and inspection, casting processing, including removal of core and casting surface foreign body, remove the riser, shovel burr and lichen and other protrusions and heat treatment, plastic surgery, rust treatment and rough processing. (Such as PN16, PN25, PN40, but there are high pressure, can go to 1500Lb ,, 2500Lb), caliber most of the DN50 or more, the pressure of the valve is very low, The Forging the valve is forged out, are generally used in the high level of the pipeline, the caliber is relatively small, generally below DN50.
