摘要

The KITEMA company has developed new types of pneumatic drive containing jet motors, namely the jet drives PSDS-2 for ball-seating valves with D_n = 150 and 200 mm, p_n = 16 MPa, as well as control devices for piston drives for ball-seating valves with D_n = 50-150 mm, p_n = 16 MPa. Figure 1 shows the scheme for the PSDS-2 drive. In 2002-3, the KITEMA company developed the PSDS-4 drive containing a jet motor (Fig. 2) for ball-seating valves having D_n = 300 and 400 mm, p_n = 16 MPa. The latter uses a scheme different from the PSDS-2, which has allowed a reduction in the size and mass for ball-seating valves of these types. The first batch of drives was made at the Rybinsk instrumentation plant in February-March 2003. At the same time, the KITEMA company has collaborated with Penza radio plant in devising a pneumatic control unit for ball valves with D_n = 300-1400 mm, p_n = 16 MPa. The device has elevated accuracy in the information on the start of movement.
