Abstract

The utility model discloses a uniform cooling device used for heat treatment of metal pipes, comprising a cylindrical sealing body with a cylindrical passage in the middle; the cylindrical sealing body is internally provided with an annular water storage chamber and a cold gas storage chamber; a water inlet and a cold gas inlet communicated with the water storage chamber and the cold gas storage chamber respectively are arranged in the cylindrical sealing body; and an annular water spraying clearance and an annular cold gas spraying clearance corresponding to the water storage chamber and the cold gas storage chamber respectively are arranged in the annular internal side surface of the cylindrical sealing body. The uniform cooling device has reasonable structural design; by adopting the cooling method in the utility model, the same section of the high-temperature metal pipe is cooled simultaneously and uniformly, thus avoiding the bended deformation of the high-temperature metal pipe owning to non-uniform cooling.

Description

A kind of homogeneous cooling apparatus for metal valve heat treatment
Technical field:
The utility model relates generally to a kind of stainless steel tube, the copper pipe refrigerating unit in thermal treatment, relates in particular to a kind of homogeneous cooling apparatus for metal valve heat treatment.
Background technology:
In the prior art, for requirement cooling fast after stainless steel tube, the copper pipe thermal treatment heating, employing is sprayed water or is directly immersed in the water to reach quick refrigerative effect usually.But, have successively because the metal tube of the condition of high temperature touches refrigerant, speed of cooling is inhomogeneous, cause shrink inhomogeneous, the metal tube bending that deforms, traditional way is to carry out machine straightening after the thermal treatment again.Metal tube thermal treatment purpose is to eliminate stress, and machine straightening can produce mechanical work stress, and this counter stress hangs down the metal tube that requires, and influences the quality of product.
Therefore, demand is a kind of can make metal tube evenly quick refrigerative device in heat treatment process.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of structure design homogeneous cooling apparatus for metal valve heat treatment cleverly to be provided.
The utility model is realized through following technical scheme:
A kind of homogeneous cooling apparatus for metal valve heat treatment; It is characterized in that: the tubular sealing member that has cylindrical channel in the middle of comprising; Be provided with annular reservoir chamber and storage cold air chamber in the tubular sealing member; Have the water-in that is communicated with reservoir chamber and storage cold air chamber respectively on the said tubular sealing member and advance the cold air mouth, the annular inboard face of said tubular sealing member is provided with corresponding with reservoir chamber and storage cold air chamber respectively annular water spray slit and annular spray cold air slit.
A kind of homogeneous cooling apparatus for metal valve heat treatment is characterized in that: said annular water spray slit and tubular sealing member axially be 30 °-45 °, the tapered water curtain of the water of ejection.
A kind of homogeneous cooling apparatus for metal valve heat treatment is characterized in that: said annular spray cold air slit and tubular sealing member axially be 30 °-45 °, the tapered cold air curtain of the cold air of ejection.
The utility model is in heat treatment process, and the metal tube of the condition of high temperature through annular water spray slit, on same cross section is fast sprayed cooling by the water of taper water curtain through the intermediary cylindrical channel; Through annular spray cold air slit, on same cross section, carried out quick jet cooling by the cold air of taper cold air curtain.
The utility model has the advantages that:
The utility model reasonable in design, such method of cooling is evenly cooled off when the pyritous metal tube is on same cross section, has avoided the hot metal pipe because the even bending that causes of inhomogeneous cooling.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to accompanying drawing.
A kind of homogeneous cooling apparatus for metal valve heat treatment; The tubular sealing member 2 that has cylindrical channel 1 in the middle of comprising; Be provided with annular reservoir chamber 3 and storage cold air chamber 4 in the tubular sealing member 2; Have respectively the water-in 5 that is communicated with reservoir chamber 3 and storage cold air chamber 4 on the said tubular sealing member 2 and advance cold air mouth 6, the annular inboard face of said tubular sealing member 2 is provided with respectively the annulars water spray slits 7 and annular spray cold air slit 8 corresponding with reservoir chamber 3 and storage cold air chamber 4.
Annular water spray slit 7 axially is 30 °-45 °, the tapered water curtain of the water of ejection with tubular sealing member 2.
Annular spray cold air slit 8 axially is 30 °-45 °, the tapered cold air curtain of the cold air of ejection with tubular sealing member 2.
During work, metal tube 9 is through in the intermediary cylindrical channel 1.
