Description

(54 GAS-TEMPLE PROTECTION SCAFANDER

The invention relates to individual means of protecting a person working under conditions of high temperatures and gassing, and can be used in the mining industry, in the metallurgical industry, and so on.

A respirator is known that includes a mouthpiece, a mouthpiece box, an exhalation hose, an exhalation valve, a regeneration cartridge, a tee tube, a breathing bag, a tank with liquid oxygen, an inspiratory valve, an inspiratory hose and a poison valve 1.

Its disadvantage is the complexity of the design, the inconvenience of operation. In addition, the respirator is a source of additional heating of the human body and greatly increases the possibility of thermal shock.

The closest technical solution to the invention is a gas-jet spacesuit containing a suit with a helmet and a life support system located inside the suit and including a reservoir with a liquid breathing mixture with nozzles of dressing and drainage and perforated flexible tubes t21.

The low performance of the spacesuit is due to the insufficiently high reliability of the life support system and the complexity of its design.

The aim of the invention is to improve the performance of the spacesuit by increasing the reliability of the life support system and simplifying its design.

Claims (2)

This goal is achieved by the fact that in 1 proposed gas-heat protection skands containing a suit with a helmet and a life support system located inside the suit and including a reservoir with a liquid breathing mixture with nozzles of refueling and drainage and perforated flexible tubes, the life support system is equipped with a cooler circulating air, inlet and outlet tubes, and a fan, which, together with perforated flexible tubes, form a closed circuit; A gas outlet pipe from a tank with a liquid breathing mixture is connected to a circulation cone behind the tank. The tanks are made of oexeKaeNJUMHj in the shape of a person’s feet and are located in pockets, the lower parts of the trouser’s trouser legs. Figure 1 shows the spacesuit, a general view; Fig. 2 shows the system of providing the woman's life in Fig. 3 — a reservoir of liquid respiratory mixture. The gas-and-heatsuit space suit consists of a suit with a helmet 1, inside of which are perforated tubes 2 for suctioning air from the spacesuit and the pressure tube 3: cooled air into the spacesuit. CHCTeivM reserves of 4 life support sizes in the pockets of 5 spacesuits. The tank 4 consists of a housing with filling nozzles 6 and a drain 7. Inside the tank 4 there is a circulating air cooler 8 with an inlet tube 9 and an outlet tube 10. To the inlet tube 9 there is a high pressure fan 11j which is located outside the tank 4, Cooled cooler air 8 with inlet pipes 9 and outlet 10, perforated suction pipes 2 and discharge 3 and fan 11 form a closed circulation air circuit. A pipe about | B, 7 of gas from tank 4 with a liquid splatter mixture is connected to a circulation loop behind the tank. The cooler 8 is installed on the fins 12, the liquid breathing mixture is poured into the tank 4 through pipe 6, the tank body, the circulating air cooler 8, the inlet tube 9 and the outlet 1.0 are welded from titanium. Circulation BO-1D: 7X from the sub-space space ps to the tubes 2 lss-sayuyu fan 11 and the inlet tube 9 enters the cooler 8, in which the air is cooled and at the same time the exhaust gas CO is removed from it, and due to the humidity of the exhaled air and low temperature of the cooler is turned into coal kis OTU which is deposited in the form of ine on the walls of the coolant at 70 ° C). (H + CO Next, the cooled and purified air through the outlet pipe 10 enters the discharge pipe 3. At the outlet of the reservoir, the outlet pipe 10 connects with it by the outlet pipe 7, through which the vapor mixture which evaporates from the reservoir enters the circulation circuit, at the same time providing the stable operation of the whole life support system and preventing overpressure in the reservoir. The discharge pipes 7 also functioned as a microclimate regulator in the spacesuit's podorezhny space. In this space, evaporation of the liquid breathing mixture increases and the mixture enters the circulation circuit more intensively through the nozzle 7, and the amount of evaporation of the breathing mix decreases with decreasing air temperature in the underwater space. Tank 4 is compact and light, located at the bottom of the legs in karahans of the space suit. facing the body, made tight legs, which eliminates damage to them and facilitates maneuverability in the work. Technique-economic efficiency is to increase tech safety and to improve the working conditions of those working under high heat exposure conditions, resulting in increased labor productivity and reduced downtime. Claim 1. A weatherproof protective suit containing a suit, with a helmet and a life support system, located inside the suit and including a liquid breathing mixture, with refill and drain connections and perforated flexible tubes, characterized in that, in order to improve operational and technical characteristics of the spacesuit by increasing the reliability of the life support system and simplifying its design, the life support system is equipped with a circulating air cooler Having inlet and outlet tubes, and a fan, constituting together with the perforated flexible tube closed circulation circuit, wherein the gas outlet conduit from a liquid reservoir connected to the breathing gas circulating circuit for the tank. 2. A suit of claim 1, characterized in that the tanks are streamlined, shaped like a human leg and are located in the pockets of the lower parts of the spacer leg.
