Abstract
The utility model relates to a metal tube heat treatment uniformity cooling device, which comprises a circular sealing cavity body (1) with a cylindrical passage (2) at the middle part, a water inlet (3) arranged at the outer side of the circular sealing cavity body (1), and a circular water spraying interstice (4) which is arranged on the inner side face of the circular sealing cavity body (1) and connected with the water inlet (3). The utility model has the advantages that a high temperature metal tube is performed quick spray cooling by the water on the tapered water curtain through a cylindrical passage at the middle part and after passing through the circular water spraying interstice during the heat treatment process; thus, the cooling is simultaneously and uniformly performed to the high temperature metal tube on the identical section through a cooling method, and the deformation and bend of the high temperature metal tube caused by uneven cooling is avoided..
Description
Technical field
The utility model relates to a kind of stainless steel tube, the copper pipe refrigerating unit in thermal treatment, relates in particular to a kind of mouth spray structure of refrigerating unit.
Background technology
To stainless steel tube, requirement is cooled off fast after the copper pipe thermal treatment heating in the prior art, and employing is sprayed water or directly immersed in the water to reach quick refrigerative effect usually.But traditional process for cooling is adopted in metal tube thermal treatment, and the metal tube contact cooling agent of the condition of high temperature has successively, and speed of cooling is inhomogeneous, cause shrink inhomogeneous, the metal tube bending that deforms, traditional way is to carry out mechanical alignment after the thermal treatment.Metal tube thermal treatment purpose is to eliminate stress, and mechanical alignment but can produce mechanical work stress, and this influences the quality of product to the high and low metal tube that requires of stress of straight degree is arranged.
Solving metal tube evenly cooling fast in heat treatment process, is to improve the metal tube thermal treatment quality, improves the gordian technique of product quality.
Summary of the invention
The utility model technical issues that need to address have provided a kind of homogeneous cooling apparatus for metal valve heat treatment, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: a centre is the belt enclosed housing of cylindrical channel; The outside at described belt enclosed housing is provided with water-in; Described water-in joins with the slit of spraying water in the annular of the enclosed housing medial surface that goes in ring.
Compared with prior art, the beneficial effects of the utility model are: in heat treatment process, the metal tube of the condition of high temperature is a cylindrical channel by the centre, through annular water spray slit, is sprayed cooling fast by the water of taper water curtain on same cross section; Such method of cooling is evenly cooling simultaneously on same cross section to the pyritous metal tube, has avoided the hot metal pipe because the irregular bending that causes of cooling.
Description of drawings
Fig. 1 is a side cross-sectional view of the present utility model;
Fig. 2 is the three-dimensional water curtain synoptic diagram in one side of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: a centre is the belt enclosed housing 1 of cylindrical channel 2; Be provided with water-in 3 in the outside of described belt enclosed housing 1; Described water-in 3 joins with the slit 4 of spraying water in the annular of enclosed housing 1 medial surface that goes in ring;
Described annular water spray slit 4 and belt enclosed housing 1 axially be angle between 30 °-60 °, the tapered water curtain 6 of the water of ejection.
The hot metal pipe 5 of process cylindrical channel 2 is sprayed cooling at the taper water curtain 6 by slit 4 ejections of annular water spray simultaneously by taper water curtain 6 on same cross section like this, has avoided the hot metal pipe owing to the irregular bending that causes of cooling.
Claims (2)
1. a homogeneous cooling apparatus for metal valve heat treatment comprises: the belt enclosed housing (1) that the centre is a cylindrical channel (2); It is characterized in that: be provided with water-in (3) in the outside of described belt enclosed housing (1); Described water-in (3) joins with the slit (4) of spraying water in the annular of enclosed housing (1) medial surface that goes in ring.
2. homogeneous cooling apparatus for metal valve heat treatment according to claim 1 is characterized in that: described annular water spray slit (4) and belt enclosed housing (1) axially be angle between 30 °-60 °, the tapered water curtain of the water of ejection (6).
