Autor vynálezu BYSTRIANSKY MARIÁN, BŘEZNO (54) Zariadenie na prefukovanie rúrTHE INVENTOR BYSTRIANSKY MARIÁN, BŘEZNO (54) Pipe blowing device
Vynález rieši problematiku odstraňovaniaokují z rúr před defektoskopickými skúška-mi.The invention solves the problem of removing debris from tubes prior to defectoscopy tests.
Doteraz sú okuje z rúr vyfukované tlakomvzduchu cez trysku umiestnenú na pevnomstojane v predvolenej vzdialenosti od čela rú-ry. Otvorením přívodu tlakového vzduchu pojeho prvom uniknutí z trysky do rúry dochá-dza k spátnej tlakovej vine, najma u menšíchpriemerov rúr. Dochádza k znečisťovaniu pro-stredia jemnými okujami a k zvýšenej racio-nálnej spotrebe tlakového vzduchu.Up to now, blow-blown air pipes have been scaled through a nozzle placed on a stationary stand at a preset distance from the tube end. By opening the compressed air supply after its first leakage from the nozzle into the oven, there is a back pressure pressure, especially for smaller pipe diameters. There is contamination of the medium by fine scale and increased rational consumption of compressed air.
Uvedené nedostatky odstraňuje zariadeniena prefukovanie rúr, pozostávajúce zo stoja-nu s upevněnou tryskou napojenou na tlako-vý přívod vzduchu so zabudovaným rozvá-dzačom, podl’a vynálezu. Podstata vynálezuspočívá v tom, že tryska je tvořená válcovýmtelesom s vstávaným dutým piestom opatře-ným vratnou pružinou, pričom v přívodevzduchu je před hlavným rozvádzačom zařá-děný pomocný rozvádzač a za každým rozvá-dzačom je umiestnený spatný ventil. Výhodou zariadenia podlá vynálezu je, žepredná časť trysky je do rúry zasúvaná ria-diacim tlakom vzduchu. Po otvorení hlavnéhopřívodu tlakového vzduchu počas prefukova-nia rúry je súčasne prisávaný do rúry atmo-sferický vzduch. Regulovatelným zasúvaním trysky do prefukovanej rúry sa dosiahne do-konalejšieho prefúknutia rúry s menším ná-rokom na množstvo tlakového vzduchu využi-tím prisávaného vzduchu.The aforementioned drawbacks are eliminated by the tube blowing device consisting of a stand with a fixed nozzle attached to a pressure air supply with a built-in distributor, according to the invention. The invention is based on the fact that the nozzle is formed by a cylindrical telescope with a raised hollow piston provided with a return spring, wherein an auxiliary distributor is provided in front of the main distributor in the air inlet and a back valve is located behind each distributor. An advantage of the device according to the invention is that the front part of the nozzle is inserted into the oven by the control air pressure. At the same time, atmospheric air is sucked into the oven after opening the main compressed air supply during the blowing of the oven. By adjusting the insertion of the nozzle into the blown tube, a more continuous blowing of the pipe with a smaller amount of compressed air is achieved by using the suction air.
Na priloženom výkrese je schematicky zná-zorněné zariadenie podlá vynálezu, pričomusporiadanie je pneumatické.The accompanying drawing schematically shows a device according to the invention, wherein the arrangement is pneumatic.
Tryska na prefukovanie je tvořená válco-vým telesom 4, v ktorom je suvne upravenývratný dutý piest 5 pomocou vratnej pružiny 3. Celá tryska je upevněná na pevnom stoja-ne 6 a je nasměrovaná do otvoru rúry 2 v po-hyblivom žlabe 1. Rozvod tlakového vzduchuje napojený na riadiacu vetvu, ktorá pozo-stáva zo škrtiaceho ventilu 10, pomocnéhorozvádzača 12 a spatného ventilu 11 s vyústě-ním rúrového rozvodu na vstupnú časť trys-ky. Hlavný přívod tlakového vzduchu prechá-dza škrtiacim ventilom 9 cez hlavný rozvá-dzač 8 a druhý spatný ventil 7 a je napojenýna rúrový rozvod výstupnej vetvy riadiacehotlaku. K prefúknutiu rúry 2 dochádza tak, že ria-diaci tlak vzduchu je cez pomocný rozvádzač12 přivedený do válcového telesa 4, kde vy-vodí silu na čelnú časť kruhovitého prierezupiestu 5 zasunie ho do rúry 2. Otvorí sa hlav-ný rozvádzač 8, ktorým přejde hlavný přívodvzduchu na prefúknutie rúry 2. Počas prefu- 217672The blow-out nozzle is formed by a cylindrical body 4 in which a reversible hollow piston 5 is provided by means of a return spring 3. The entire nozzle is mounted on a fixed stand 6 and is directed into the opening of the pipe 2 in a moving channel 1. the air is connected to a control branch, which consists of a throttle valve 10, an auxiliary valve 12 and a valve 11 with the outlet of the pipe manifold at the inlet portion of the nozzle. The main supply of pressurized air passes through the throttle valve 9 through the main distributor 8 and the second valve 7, and the pipe outlet of the outlet branch is connected to the pressure control. The blowing of the pipe 2 is effected by supplying the control air pressure via the auxiliary distributor 12 to the cylindrical body 4, where it forces the front part of the annular cross-section 5 into the pipe 2. The main distributor 8 opens. main air supply for pipe blowing 2. During prefu-217672
