The device and principle of operation of CPEG

Valve device:


Safety shut-off valve with electromagnetic drive consists of a flanged body 1 valve type.
Inside the body there is a seat, which is blocked by the main valve 2 with rubber seal and built-in bypass valve.
The valve hangs on the stem 5, the upper end of which moves in the opening of the cover 13, and the lower end along the guide post of the body.
The valve stem is connected by means of a pin to the lever 4 mounted on the axle 3. A washer 7 is installed on the upper end of the stem with the valve actuator spring 6 sandwiched between the washer and the cover. The axle leaving the housing is sealed with rubber rings.

At the end of the axis 3, going outward, the lever 8 is rigidly fixed, which through the adjusting screw 9 is engaged with the lever 10 installed in the rack 12 fixed on the cover 13.

A bracket 14 with an electromagnet 15 and a housing 16 is attached to the cover 13. A rod 17 with a tip 23 is located in the housing (see Figures 2 and 3).
The position of the tip 23 is determined by the difference in the forces of the springs 18, 19 and the force of the electromagnet 15 transmitted to the rod 17 by the pin 20 made of non-magnetic material. The body of the electromagnet 16 is equipped with a latch 21 located on the axis 22. The latch serves to hold the valve open during technological preparation. The latch should freely rotate on the axis under the action of gravity without jerking and jamming.


Valve working principle:


The valve works as follows: the gas supplied to the valve passes through the inlet pipe to the outlet, if the voltage corresponding to this version is applied to the electromagnet 15. The latch 21 in accordance with Figure 3 must be turned off, the latch must be disengaged from the tip 23 and take a horizontal position).


When the voltage supply to the electromagnet is interrupted, the tip 23 moves along the axis. The stop 11, mounted on the lever 10, disengages from the tip 23, releasing the interconnected levers 8 and 10, allowing the axis 3 to turn and the valve 2 to close under the action of the spring 6.


Bringing the main valve 2 into working condition after operation is done manually by turning the lever 8, while the stem will first move, as a result, the bypass valve built into the main one will open. After equalizing the pressures before and after the main valve 2, the lever 8 is further raised until it engages with the lever 10 and fixes them with the tip 23 (see Figure 2).

Valve 2 is held open. The electromagnet is connected to the network. The latch is disengaged as shown in figure 3. The valve is ready for operation.

The use of electromagnetic valves is justified if the gas control point is located at a great distance from the gasification facility, and also if the reduction point is equipped with a telemetry complex - in this case, control over the operation of the installation is greatly simplified. The valve with an electromagnetic drive can be closed forcibly, at a distance, both in the event that the controlled parameters go beyond the specified limits, and during normal operation, for routine inspection or other actions of the maintenance personnel.

The device and principle of operation of KPEG-M

The valve has (see the figure) a body 1 with a seat, which is closed by a valve 2 with a rubber seal 20, fixed on the axis 3. At the end of the axis that goes outward, a lever 6 is rigidly fixed, which is engaged with the lever 7. An electric drive is fixed on the body 1, consisting of an electromagnet 8 with a housing 9, in which a rod 10 with a sleeve 11 is located.

The body of the electromagnet 9 is equipped with a latch located on the axis 17. The latch serves to hold the valve in the open state during the technological preparation of the equipment. The gas supplied to the valve passes through the inlet pipe to the outlet, if the voltage corresponding to this version is applied to the electromagnet 8.

When the voltage supply to the electromagnet is interrupted, the sleeve 11 moves under the action of the spring 13. The stop 12, mounted on the lever 7, disengages from the sleeve 11, releasing the interconnected levers 6 and 7, and allows the axis 3 to turn.

The force from springs 4 and 5 is transferred to valve 2. Valve 2 closes the gas passage.

The KPEG valve has a body 1 with a seat (Fig. 1), which is closed by a valve 2 with a rubber seal 20. The valve 2 is fixed on the axis 3, which is located in the body 1. Springs 4, 5 are installed on the axis 3. At the end of the axis 3, outgoing outside, the lever 6 is rigidly fixed, which interacts with the lever 7. An electromagnetic drive is fixed on the body 1, consisting of an electromagnet 8 with a body 9, in which a rod 10 with a sleeve 11 is located (Fig. 2, Fig. 3).

The body of the electromagnet 9 is equipped with a latch 16 located on the axis 17. The latch serves to hold the valve open during the technological preparation of the equipment. The latch 16 must freely rotate on the axis 17 under the action of gravity without jerking and jamming.

The gas supplied to the valve passes through the inlet pipe to the outlet, if the voltage corresponding to this version is applied to the electromagnet 8. Latch 16 in accordance with fig. 3 must be turned off (i.e., the latch must take a horizontal position).

When the voltage supply to the electromagnet is interrupted, the sleeve 11 moves under the action of the spring 13. The stop 12, mounted on the lever 7, disengages from the sleeve 11, releasing the interconnected levers 6 and 7, and allows the axis 3 to turn. The force from springs 4 and 5 is transferred to valve 2, and valve 2 closes the gas passage.

Bringing the valve into working condition after actuation is done manually by turning the lever 6, while the bypass valve built into the valve 2 opens first. After equalizing the pressure before and after valve 2, the lever 6 is further raised until it engages with the lever 7 and fixes them with the sleeve 11 (Fig. 2)

Valve 2 is held open. The electromagnet is connected to the network. The latch is turned off in accordance with Fig.3. The valve is ready for operation.
