FIELD: machine building. ^ SUBSTANCE: invention can be implemented in multi-input taps controlled with one element applied in pneumatic systems of high pressure. The disk pneumatic T-valve consists of a case, of a case cover with a hold down spring rigidly tied with the case by means of a threaded connection, of a selector valve and of a valve switch. The switch is installed in a through axial aperture of the case. The valve is arranged between the hold down spring and the case, has a split connection with a working end of the switch and is designed to perform forced turn around axis of the case at 90. Through cylinder channels are made radially in 90 in the case along circumference with centre on the axis of the case: they are an inlet channel, working the first and the second channels and the channel for air bleeding. The selector valve corresponds to a disk. Shaped identical extensive recesses are made in the body of the disk in cross opposed sectors; the recesses are formed with arcs of circumferences with centre coinciding with centre of the disk. At the turn of the disk at 90 to one or another side of the recess one working channel is connected with the inlet channel, while another is connected with the channel for air bleeding. The case of the valve, the cover and the switch of valve position are made out of Caprolon. The selector valve is made out of graphitised Caprolon. ^ EFFECT: simplification of valve fabrication and maintenance, expanded facilities for fabrication of dick pneumatic T-valves. ^ 4 dwg |
