The KPEG valve has a body 1 with a seat (Fig. 1), which is closed by valve 2 with rubber seal 20. Valve 2 is fixed on axis 3, which is located in housing 1. Springs 4, 5 are installed on axis 3. At the end of axis 3, extending outward, a lever 6 is rigidly fixed, which interacts with lever 7. An electromagnetic drive consisting of from an electromagnet 8 with a housing 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 technological preparation of the equipment. The latch 16 should rotate freely on the axis 17 without jerking or jamming under the influence of gravity.

The gas supplied to the valve passes through the inlet pipe to the outlet pipe if the voltage corresponding to this design is supplied to the electromagnet 8. Clamp 16 in accordance with Fig. 3 should be turned off (i.e. the latch should take a horizontal position).

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

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

Electromagnetic valve CPEG installed on the hydraulic fracturing and main distribution points of low and medium pressure gas pipelines, cuts off the gas supply to the consumer when the gas pressure in the system leaves the specified limits. The command mechanism in in this case is an electromagnet that controls the springs of the sleeve, which, when the pressure changes, blocks the flow of gas. Valve CPEG after activation, it is brought to its original position manually, and there is no need to dismantle it from the gas pipeline system.

Safety solenoid valves KPEG are among the most requested shut-off valves. Their high popularity is explained by the design simplicity of the valves, high quality sealing of the gas distribution system when triggered, as well as high reliability and trouble-free operation. The last of the listed advantages of the KPEG valve are largely provided by the properties of the material from which it is made. Typically this is 20 steel - a stainless and heat-resistant alloy that allows the KPEG valve to operate in the temperature range from -60°C to +100°C.

KPEG solenoid valves have virtually no alternative solutions security issues gas pipelines in the case where the gasification facility is significantly removed from the gas control point or when the reduction point is equipped with a telemetry system. In this case, the use of solenoid valves greatly facilitates control over the operation of the installation. Closing the CPEG valve can be done remotely for various purposes - it can be an exit controlled parameters operation of the system from a given range, as well as the need to perform preventive inspection or repair by specialists servicing the gas supply system.

Another specific feature of the use of KPEG shut-off valves is that they are mounted on pipelines small diameter(50-100 mm). This is explained by the factors that large diameters pipelines, the force required to close the valve is very high, which requires slightly more complex design fittings for complete tightness of closing the valve plug when it is lowered onto the seat steel body CPEG.

Marking of electromagnetic valves KPEG

The number in the marking indicates the diameter of the pipe at the entrance to the flange connection of the KPEG valve - KPEG 50, KPEG 100, KPEG 100p, KPEG 50p. The index “p” after the diameter means that when the electromagnet of this valve operates, the current is alternating.

Design and principle of operation of CPEG

Valve device:

The safety shut-off valve with an electromagnetic drive consists of a flanged housing of 1 valve type.
Inside the body there is a seat, which is closed by the main valve 2 with a rubber seal and a built-in bypass valve.
The valve hangs on a rod 5, the upper end of which moves in the hole of the cover 13, and the lower end along the guide post of the body.
The valve stem by means of a pin engages with a lever 4 mounted on axis 3. A washer 7 is installed on the upper end of the stem with a valve drive spring 6 clamped between the washer and the cover. The axle coming out of the housing is sealed using rubber rings.

At the end of the axis 3, which extends outwards, a lever 8 is rigidly fixed, which, through an adjusting screw 9, is engaged with a lever 10 installed in a rack 12 fixed to the cover 13.

A bracket 14 with an electromagnet 15 and a housing 16 is attached to the cover 13. The housing contains a rod 17 with a tip 23 (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 a pin 20 made of a 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 rotate freely on the axis without jerking or jamming under the influence of gravity.

Valve operating principle:

The valve operates as follows: the gas supplied to the valve passes through the inlet pipe to the outlet pipe if the voltage corresponding to this design is supplied 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 stopped, 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 rotate and the valve 2 to close under the action of the spring 6.

Bringing the main valve 2 into working condition after actuation is done manually by turning the lever 8, while the rod 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 turned off in accordance with Figure 3. The valve is ready for operation.

The use of solenoid 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, monitoring the operation of the installation is greatly simplified. A valve with an electromagnetic drive can be closed forcibly, at a distance, both in the event of controllable parameters leaving the specified limits, and during normal operation, for carrying out preventive inspections or other actions of maintenance personnel.

Note - During installation, it is allowed to install KPEG-50, KPEG-100 vertically. In this case, the valve of the shut-off element should be located at the top, and the magnet mechanism should be rotated 90 degrees relative to its axis. The latch must be located in a vertical plane.

Design and principle of operation of the electromagnetic gas valve CPEG.
1 . The KPEG valve has a body 1 with a seat in accordance with Figure 1. The body seat is covered by a valve 2 with a rubber seal 20. Valve 2 is mounted on an 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, extending outwards, a lever 6 is rigidly fixed, which interacts with the lever 7.

2. An electromagnetic drive is fixed to the housing 1, consisting of an electromagnet 8 with a housing 9, in which a rod 10 with a sleeve 11 is located (see Figures 2 and 3). The position of the sleeve 11 is determined by the force of the springs 13, 14 and the force of the electromagnet 8, transmitted to the rod 10 by a pin 15, made of non-magnetic material. 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 technological preparation. The latch 16 should rotate freely on the axis 17 without jerking or jamming under the influence of gravity.

3. The gas supplied to the valve passes through the inlet pipe to the outlet pipe if the voltage corresponding to this design is supplied to the electromagnet 8. The latch 16 in accordance with Figure 3 must be turned off (i.e., the latch must take a horizontal position). When the supply of voltage to the electromagnet is stopped, the sleeve 11 moves. The stop 12, mounted on the lever 7, disengages from the sleeve 11, releasing the interconnected levers 6 and 7, allowing the axis 3 to rotate. The force from springs 4 and 5 is transmitted to valve 2, and valve 2 closes the gas passage.

4. Bringing valve 2 into operating condition after actuation is done manually by turning lever 6, while the bypass valve built into 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 (see Figure 2). Valve 2 is held open. The electromagnet is connected to the network. The latch is turned off in accordance with Figure 3. The valve is ready for operation.
