Embodiment Construction

[0020] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0021] Such as figure 1 as shown, figure 1 A schematic structural diagram of an embodiment of the present invention is shown. This embodiment is used for the fluid medium shunting structure of the warm isostatic working cylinder, including the working cylinder body 101, the bottom of the working cylinder body 101 is provided with a lower end cover 104, and the lower end cover 104 is provided with a medium inlet 105, a certain temperature And ultra-high pressure liquid medium enters the cylinder body of the working cylinder from the medium inlet 105. If the size of the medium inlet 105 is too small, the inflow and outflow speed of the medium will be slow, resulting in heat loss of the medium. If the size of the medium inlet 105 is too large, the seal of the medium inlet 105 will easily leak under high pressure, especially an ultra-high pressure environment. As a pref...

Abstract

The invention discloses a fluid medium diversion structure for a thermal isostatic-pressing working cylinder. The fluid medium diversion structure comprises a cylinder body and a diversion plate. A lower-end cap is arranged at the bottom of the cylinder and a medium inlet is reserved on the lower-end cap. The diversion plate is arranged above the lower-end cap; the impact of the inflowed medium to the product is blocked by the diversion plate and a gap is reserved between the diversion plate and the lower-end cap. By the fluid medium diversion structure in design, the medium flows into the cylinder is diverted in the radial direction by of the aid of the diversion plate, so that impact of the medium to the product in the cylinder and local heating of the product are prevented. The cycling of heat exchange is established by the medium diversion structure, the heat medium is forced to flow into the cylinder, and temperature reduction of the medium due to heat dissipation of the cylinder body is compensated.

Description

technical field [0001] The invention relates to a fluid medium flow distribution structure, in particular to a fluid medium flow distribution structure for a warm isostatic working cylinder. Background technique [0002] Warm isostatic pressing technology, the pressing temperature is generally at 80 degrees Celsius to 120 degrees Celsius. There is also a special liquid or gas transmission pressure at 250 degrees Celsius to 450 degrees Celsius, and the working pressure is about 300MPa. It is mainly used for graphite, polyamide rubber materials, etc. that powder materials cannot be molded at room temperature. In order to obtain a solid green body at elevated temperature. [0003] In the prior art, the interior of the medium-temperature isostatic working cylinder uses liquid at a certain temperature and ultra-high pressure as the pressure medium. When the medium flows into the working cylinder, heat exchange occurs between the medium and the working cylinder, which will cause...
