摘要：
The authors studied the thermal state of a shut-off valve having a nominal bore diameter D//n equals 55 mm with three versions of the design of the sliding device: with guiding blades (version I); without guiding blades and, with larger inner diameters (versions II and III). The distinctive features of the sliding devices are given. The data obtained suggest that the pattern of variation of the temperature of the neck wall and the temperature of the working medium in the neck of the valve having sliding devices of various designs is different. The heat exchange is more vigorous in the neck of the valve having a sliding device of version I than in the neck of the valve having a sliding device of version II. This can be attributed to the presence of additional agitators in the flow part of the valve.
