Abstract

The gate valve will find use in branched pipe eoustavaoh with multi-position intelligence, especially "ve staóionárníolj and semiataoionární rain systems. The task of the solution is to create a bath stop valve, reliably processing hydraulic control signals independent ha ryohosti their shaping and not requiring a high degree of water purity for irrigation. Slide gate valve consists of a gate valve installed on ducting, cylinder with piston connected from his party with programmaticism, and a water tank. V extended parts rolled the gate valves from the side the inlet opening of the pipe deflection are longitudinal channels and gate valves are provided is the cavity in which the head is freely placed connected by a front axle to a piston placed in the cylinder. The cavity passes the hole from one side and the cylinder by the first axial the holes are connected to the soup mezikomorou. In the side surface of the cylinder there are. four rows of holes, the first two encircles the first outer annular chamber, and the other two, the second outer ring chamber, connected by means of an opening and a water tank. A second and third row of holes are provided with flexible rings, and drilled in the bottom of the cylinder the second axial hole through which the rear the axis firmly attached to the piston, to its other the end is transversely connected freely rotating around the rear axle cam, whose outer the end is stored in the program channels with short .and long running programm
