Abstract

The invention relates to fire fighting equipment, in particular, to means preventing the spread of explosion products of dust from equipment in which they are formed into ducts designed to transport both hot dust and purified air, and allows for increased efficiency during operation. Ode 10 7 those devices due to water cooling of the explosion products. Explosive device includes a case 1 with an inlet pipe 2 placed inside it and a rupture disk 3 made of a polymeric material, for example, a polyethylene film with a thickness of 100 μm, and installed in the case coaxially with the inlet pipe. Perpendicular to the inlet pipe 2, a gas outlet pipe 4 is attached to the housing 1. The device is equipped with a pressure relay 5 installed in the inlet pipe 2 and mounted on the gas outlet pipe 4 nozzles 6. valve diaphragm with stimuli chambers 7, as well as an incentive pipeline 8 with electromagnetic the valve 9. The stimulus chambers 7 are interconnected by the stimulus pipeline 8 and through the solenoid valve, which is electrically connected to the pressure relay 5, to the atmosphere. The nozzles 6 are connected to the water supply line 10, to which an incentive pipeline 8 is connected via a stop valve 11. 1 Il. C & O5 vl MLOALO

Description

a velocity flow of air and explosion products, the main part of which is removed from the housing 1 through the membrane 3 when it is destroyed. However, this does not exclude the possibility of explosion products getting through the gas outlet pipe 4 into the air duct, i.e., into the workshop or to workplaces.

Simultaneously with the increase in pressure in the inlet nozzle 2, the relay 5 is actuated by the pressure to the gas outlet nozzle 4.

The use of the proposed device will prevent the spread of flame through the ducts with access to the shop and to the workplace after an explosion of dust in

The invention relates to fire fighting equipment, in particular to means preventing the spread of dust explosion products from equipment in which they are formed into ducts designed to transport both combustible dust and purified air. The aim of the invention is to improve the efficiency of the device due to water cooling of the explosion products.

The drawing shows the proposed 10 idlers, which sends a signal to the electric device, a general view of the magnetic valve 9. The last message I The explosive suppressor device includes an incentive pipeline 8 with an atmosphere of the case 1 with a ferry placed inside, the pressure in it drops. In this case, the inlet pipe 2 and the bursting pressure drops in the stimulating chambers 7, the membrane 3, made of polymer nozzles b, which work and serves

l material such as plastic film -

T0LsHCHINOY 100 microns, and installed in the box coaxially with the inlet nozzle. A gas outlet pipe 4 is attached to the housing 1 perpendicularly to the inlet nozzle 2. The device is equipped with a dust cleaning equipment installed in the inlet-20, a pressure relay nozzle 2 of the nozzle 2 and mounted on the exhaust nozzle 4

nozzles 6, valve membranes with stimulating chambers 7, as well as a boom-blasting device, an inlet pipe 8 with an electromagnet housing with a note valve 9 placed inside. The incentive chambers 5, the inlet branch pipe and a rupture memo 7 communicate with each other booster mounted in a housing coaxially

an inlet pipe, and a gas outlet pipe connected to the case perpendicular to the inlet pipe, wherein in order to increase its efficiency by water cooling of the explosion products, it is equipped with a pressure relay mounted in the B. Connection pipe mounted on the gas outlet pipe nozzles, valve membranes In the absence of an explosion in the equipment, with stimuli chambers and bypassing combustible dusts, a dust piping with electromagnetic air passes through the air the hose (not a leaky valve, while the incentive is shown) and through the inlet 2, the nozzle chambers communicate with each other into the housing 1, and then into the gas-stimulating pipeline and through the electrical outlet 4. In the event of an explosion, a solenoid valve connected to the bottom of the inlet nozzle 2, a high pressure of 40% occurs, - with the atmosphere.

through a pipe 8 and through an electromagnetic valve, which is electrically connected to the pressure switch 5, to the atmosphere. The nozzles 6 are connected to the water supply line 10, to which the stimulus pipe line is connected via the shut-off valve-11.

I The device works as follows.
