The gas distribution grid is made of magnetically hard material.

The invention relates to pipe fittings and can be used in systems for throttling the shutoff or switching of gas flow. A pilot-regulating device is known, which contains a vertical conical body with a fixed gas distribution grid and a ferromagnetic attachment inside it, a magnet encircled outside by a wire, the lower part of the inner surface of which is made in the form of a truncated cone Cl3. A disadvantage of the known device is that for its successful operation as a ferromagnetic nozzle, it is necessary to use a fine bulk material to create a sufficiently large hydraulic resistance, but the smaller the particle sizes, the greater the velocity of their entrainment by gas flow, which limits the throughput of the mouth roystva The purpose of the invention is to increase the capacity. The goal is achieved by the fact that the locking device, containing a vertical conical body with a fixed gas distribution grille placed inside it and a ferromagnetic nozzle enclosed from the outside by a matte duct, the lower part of the inner surface of which is truncated cone, is equipped with a mobile gas distribution a lattice loaded with a spring in the direction open and placed between the ferromagnetic nozzle and a fixed lattice made with conical holes, and ferromagnetic ball closures located along the axes of the conical holes, the cones of the magnetic circuit and the housing being combined with large bases. In addition, the stationary gas distribution grid is made of magnetically hard material. The drawing shows a locking-regulating device, a slit. A vertical body 1, made in the form of a truncated cone, is enclosed by a solenoid 2 with a magnetic core 3, the lower part of which is made under a truncated cone, pressed to the plane of the base by a spring 4, a gas distribution grid 5, on which in the absence of a magnetic field lies a layer of ferromagnetic attachment b. Under the movable grill 5 there is a fixed gas distribution grill 7 with conical apertures, inside of which ferromagnetic ball valves 8 are freely placed. To the lower part of the magnetic conductor 3 there is attached pipe 9 for gas supply. The locking control device operates as follows. In the absence of voltage on the solenoid 2, a layer of ferromagnetic attachment b lies on the movable grid 5 and compresses the spring 4 with its weight. The mobile grid 5 descends and presses against the ferromagnetic ball valves 8, the latter are pressed against the conical surfaces of the holes in the grid 7, blocking the gas flow. The valve is closed. After applying voltage to the solenoid 2, a layer of ferromagnetic attachment 6 is placed between the magnetic poles of the magnetic circuit 3. Under the action of the springs 4, the gas distribution grid 5 moves away from the fixed grid 7, releasing the ferromagnetic ball valves 8, if the gas pressure in the port 9 is sufficient, then the ferromagnetic ball valves 8 are ferromagnetic the ball locking bodies are pressed out from the conic holes of the fixed grid 7, opening the passage to the gases. The locking device is open. Such a mode of operation of the device is possible, in which the ferromagnetic attachment 6 is weighed at the time of imposing a magnetic field pulse and falling in the interval between pulses: the gas flow will pulsate with the frequency of the magnetic field. Making the gas distribution grid of magnetically hard material creates a large force, blocking the gas flow, exceeding the flow coupling force FP 0.5 V 2 S and the force that would have arisen if the additional grid would be nonmagnetic (here B is the residual induction, 5 - area
