Description

one,

The invention relates to a valve.

The aim of the invention is to increase speed by increasing the speed of opening the output line.

The drawing schematically shows the device, a general view. with a gap.

In case 1, the following are made: coaxial inlet 2 and outlet 3 of the main line, perpendik-ul p1ade of the stepped boring-GS6; 4 buildings

Entrances and exits are blocked by a locking organ consisting of two symmetrical parts 5 (the second part is not shown in the section) compacted by the ends 6

The locking organ with the opposite

on each side of the rod 7 is associated with control procedures 8.

The cavity 9 of the housing bore, closed between each piston and the housing, communicates with a receiver 10 installed in front of the output line and with a drain through a three-way distributor 11, each part of which is filled with an angular position lock made in the form of a pin 12 fixed to the housing. passed through a hole in the piston.

In the torda of each part of the locking body is made with an offset from

The piston axes in the direction of the inlet line are an additional boring 13, and also a radial hole 14 is made, indicating the bore cavity 13 and the inlet highway.

The device works as follows.

In the closed position, the working medium supplied from the receiver 10 to the input line 2 at the specified pressure simultaneously enters the cavities 9 and. I act on the control ports 8, presses the friend to the friend. The GU part of the locking organ. Thus, 5 the working medium is used to control the locking member.

When switching valves 11, cavity 9 is uncoupled from the input line and communicates with the drain. As a result, a pressure drop is created on the pistons 8, which ensures the movement of the parts of the closure member from each other against the stop in the housing and the communication of the inlet and outlet lines.

The presence of a bore 13, offset from the axis of the pistons towards the inlet line, creates torque to compensate for torque on parts of the valve from pressure differences in the inlet and outlet lines x, which can cause the piston to skew and jam it in the housing.
