Description

The invention relates to reinforcement. mainly to distribution devices for controlling pneumatic and hydraulic measuring devices installed on gas mains; with a working pressure of 4-10 MPa, as well as in other automatic control systems operating at high pressure

The aim of the invention is to expand the operational capabilities by ensuring the orientation of the inlet and outlet nozzles relative to the installation pipelines, as well as by ensuring the operation of the valves from which the housing is assembled

devices (both separate functional units, and in interrelation between each other), in addition, they (valves) can be assembled in any order depending on their functional purpose.

FIG. 1 shows a distribution device (partial section); in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. one; in fig. 5 is a sectional view BB in FIG. one; in fig. 6 is a cross-section of the FIG. 3; Fig.7-node I in FIG. 6; in fig. 8 is a section DD in FIG. one; in fig. 9 is a section of the EE of FIG. eight.

ABOUT

The switchgear housing consists of valves 1-5, hermetically interconnected by studs 6.

A self-centering valve 7 with a handle 8 is installed in the body of each valve. Radial inlets 9 are installed diametrically opposite to the locking bodies 7, The device has axial outlets 10 located on valves 1 and 5 and radial outlets 11 located on valves 1, 2, 4, and 5, which are connected to the chamber 12 of each valve by a radial channel 13 at an angle to the locking member 7, the number of nozzles being due to the necessity of multiplying the input signals. The valves 1 and 2, 4 and 5 are connected in pairs by central channels 14 connecting the chambers 12, the valves.

The interventilary connection is carried out inclined to the locking organ by channels 15 and 16, which are made in the centrally located valve 3 at different angles of inclination.

Valves 1 and 5 are interconnected by peripheral channels 17, made in the housing of each of them, bypassing the locking bodies of intermediate valves 2, 3 and 4 and connecting the axial outlets 10c with radial outlet pipes 11. A similar connection can be made between the valves 2 and 4, installed with the possibility of rotation relative to each other.

The device works as follows.

In the initial state, at the location of the locking bodies 7 of the first and fifth valves, as shown in the drawing, two different signal levels (for example, from the plus and minus diaphragm chambers) go to the radial inlet nozzles 9. Through the central channels 14 these signals are passed to the output axial and radial nozzles 10 and 11. At the same time, the positive signal from the first valve through the peripheral channel 17 is fed to the output radial nozzle 11 of the fifth valve, and the negative signal from the fifth valve

through its peripheral channel 17 enters the radial outlet of the first valve 11.

During the verification work, valves 1 and 5 are closed and valves 3 and 4 are opened. At the same time, through the output radial port of valve 4, pressure is released into the atmosphere. Then the valves 3 and 4 are closed and the valve 2 opens.

Then the incoming test pressure through the central channel 14, the chamber 12 and the radial channel 13 passes to the outlet nozzles 10 and 11 of the valve 1. At the same time, the same signal through the peripheral channel

17 enters the nozzle 11 of the valve 5. To bring the switchgear to its initial state, the valve 2 is closed, the valve 3 is opened, the valves 1 and 5 are opened, then the valve 3 is closed.
