uz.f The invention relates to mining industry and may not be useful in assessing the explosion-proof properties of sprinklers and other means designed to suppress and prevent methane and dust explosions from mining machines. A device for the investigation of ignition of P1lpevosdushnyh before electric, which includes an ignition chamber with an ignition source and a delivery system, is known. .-. - The device for op | the explosion of the explosive properties of the sprinklers; the ignition chamber with a source of all 5smd mV and an explosive gas mixture feed system; and the sprinkler with a hose for supplying water; G23. - /:.; . , . . ..., The underexposure of a known device is the low accuracy of determining explosion protection. irrigation properties. The purpose of the Inventions is to improve the accuracy of the determination of the explosion-proof properties of the sprinklers by providing the opportunity to study the explosion-proof properties at various points of the irrigation facility i. an explosive gas mixture supply system, as well as a sprinkler with a 0 hose for water supply, the igniter chamber) is inserted in the form of a transparent tube open at the ends, and the source: osplameneim -to yide heater "CH1 helix, the apparatus is provided with two mTaTHBatei, Ha one of which is mounted movably igniting Kiaer, on the other - with the sprinkler hose For VOD..Na supplying FIG. 1 The proposed device is shown for determination. The protective properties of the spray agent FIG. 2 igniter: camera. The device consists of a nozzle 1, mounted on a tripod 2. Nozzle 1 is connected to the installation 3 37. . 2 by means of a hose 4 with a valve 5. In the nozzle torch ton on tripod 6, an ignition chamber 7 is installed in a tube with transparent walls and open ends, which is connected to the methane balloon by means of a hose 8 and a capillary tube 9. 11. The ignition chamber 7 together with the tripod 6 can be moved along the longitudinal axis and along the section, of the torch of the nozzle 1 to any point. Inflammatory chamber 7. consists of spacer rings 12, shell 13 for fastening to the tripod 6, quartz transparent cylinder 14 long. 200 mm and a diameter of 50 mm. Inside the chamber 7 there is an ignition source in the form of a heating coil 15 connected by means of T6 to the autotransformer 17. Device. {Works in the following way. Water is supplied to nozzle 1 via hose 4 from pump unit 3. The ignition chamber T is placed in the nozzles t. When the ignition source 15 is heated to a temperature Cp (the current is controlled by the transformer 17), the methane is supplied to the igniter chamber 7 through the capillary tube 9 and the Hose 8; It ignites from the helix 15. By moving the igniter chamber 7 through the torch of the nozzle 1, methane is released or extinguished with different operating parameters of the nozzle 1. Thus, it is important to determine and evaluate the explosion-proof properties of the nozzle and irrigation systems of the combine before lowering them into the shaft, as well as other means of irrigation. one. .-.-. :. In comparison with the known device, the use of the proposed inventions will ensure an accurate selection of the parameters of the irrigation means using. “) It is the explosion protection of the friction spark in the mine workings. Besides . tq.Q-., currently tested,. explosives explosives. The properties of irrigation equipment can only be carried out in organizations conducting state control tests. ; Due to the fact that the invention does not require large expenditures of labor and materials for the manufacture, a large 1 () asphid metan is structurally simple.

Its application will allow in a short time to carry out tests of explosion-proof properties as in NS when performing research works, teak and at plants that produce irrigation equipment.
