Abstract
Spojenie častí výbuchovej komory sa dosahuje posobením statického tlaku hydraulického valca cez aspoň jeden pružný element. Riešenie je využitelné na pracoviskách, ktoré sa zaoberajú skúšaním hořlavosti a výbušnosti sústav plyn — plyn, plyn — kvapalina alebo plyn — tuhá fáza.Connection of explosion chamber parts is achieved static hydraulic pressure the cylinder through at least one resilient element. The solution is usable in the workplace that deal with flammability testing and explosion of gas-gas, gas-liquid systems or gas - solid phase.
Description
Vynález rieši ovládanie častí výbuchovej komory, pričom podmienky sú volené tak, že konštrukčnou obměnou sa v podstatné] miere priaznivo ovplyvní stabilita, hermetičnosť a predovšetkým bezpečnost skúšobného systému pri práci.The invention solves the control of the parts of the explosion chamber, the conditions being chosen such that the stability, hermeticity and in particular the safety of the test system at work is positively influenced by the structural modification.
V súčasnosti zisťovanie technicko-bezpečnostných parametrov sa realizuje v zariadeniach, v ktorých časti výbuchovej komory sú viazané skrutkovými, bajonetovými a svorkovými spojmi (ČSSR pat. č. 99 073, č. 113 224, CSSR AO č. 180 528, č. 225 878, ZSSR AO č. 347 646, č. 788 940, fy literatúra Adolf Kuhner AG a i).At present, the technical-safety parameters are surveyed in equipment in which the parts of the explosion chamber are connected by screw, bayonet and clamp connections (ČSSR Pat. No. 99 073, No. 113 224, CSSR AO No. 180 528, No. 225 878). , USSR AO No. 347 646, No. 788 940, Adolf Kuhner AG et al.
Používané zariadenia neumožňujú pri zaistení požadovanej bezpečnosti prevádzky rýchle čistenie komory, úpravy, resp. opravy súčastí.The equipment used does not allow quick cleaning of the chamber, modifications, resp. component repair.
Uvedené nedostatky rieši tento vynález, podlá ktorého výbuchová komora k skúšaniu hořlavosti alebo výbušnosti sústav plyn — plyn, plyn — kvapalina aleho· plyn — — tuhá fáza s hydraulickým ovládáním dosahuje spojenie svojich častí posobením statického tlaku. hydraulického valca cez aspoň jeden pružný element.The above-mentioned drawbacks are solved by the present invention, according to which an explosion chamber for testing the flammability or explosiveness of gas-gas, gas-liquid or gas-solid systems with a hydraulic control achieves the connection of its parts by static pressure. a hydraulic cylinder via at least one spring element.
Medzi výhody vynálezu patří časovo nenáročná rozpojitelnosť spoja predovšetkým jeho stabilita a hermetičnosť v širokom rozmedzí tlakov od vákua až po· vysoké tlaky, ktorých použitie je vymedzené statickým tlakom kvapaliny, mechanickými charakteristikami pružného elementu a konstrukčně materiálovým riešením výbuchovej komory.Advantages of the invention include the low-time disconnectability of the joint, in particular its stability and hermeticity in a wide range of pressures from vacuum to high pressures, the use of which is defined by static liquid pressure, mechanical characteristics of the elastic element and structurally material solution of the explosion chamber.
Využitie vynálezu je možné u výbuchových komor róznych tvarov napr. válcových, gulOvých, kónických a pod.The use of the invention is possible in explosion chambers of different shapes, e.g. cylindrical, spherical, conical and the like.
Zariadenie podfa vynálezu reprezentuje nasledujúci příklad, ktorý ho· neobmedzuje, pretože posobenie hydraulického motora na pružný element móže mať podobu dalších konštrukčných alternativ vzhfadom na druh skúšok.The device according to the invention is represented by the following non-limiting example, since the engagement of the hydraulic motor on the resilient element may take the form of other design alternatives with respect to the type of test.
PříkladExample
Zariadenie na obrázku k stanoveniu technicko-bezpečnostných parametrov sa skládá z výbuchovej komory tvaru gule 1, ekvatoriálne rozdelenej na dve polgule. Príslušenstvom výbuchovej komory sú obyčajne ohřev, snímač tlaku, indikačně termočlánky, zdroj iniciácie, přívody skúšaných látok, odvody splodín atd. Dolná polgufa je prostredníctvom rámu 2 a ocelověj pružiny 3 spojená s hydraulickým valcom 4, ktorý pritláča oproti tlaku ocelověj pružiny 3 obidve polgule. Tlak v hydraulickom válci 4 sa meria pomocou manometre 5. Po dosiahnutí požadovaného tlaku v hydraulickom válci 4 je tlak blokovaný hydraulickým zámkom 6. Tlak v hydraulickom válci 4 sa dosiahne přepnutím skupinového rozvádzača 7 do polohy „uzatváranie“ pri zapnutom elektrickom motore, ktorý ovládá pohon čerpadla 8 pre hydraulický olej. Na výkrese pre úplnost sa ďalej nachádza nádržka 9 s olejom a filter 10.The device in the figure for the determination of technical-safety parameters consists of a ball-shaped explosion chamber 1, equatorially divided into two hemispheres. Accessories of an explosion chamber are usually heating, pressure sensor, indicating thermocouples, source of initiation, inlets of test substances, exhaust of gases etc. The lower hemisphere is connected to the hydraulic cylinder 4 by means of a frame 2 and a steel spring 3, which presses both hemispheres against the pressure of the steel spring 3. The pressure in the hydraulic cylinder 4 is measured using a pressure gauge 5. After reaching the desired pressure in the hydraulic cylinder 4, the pressure is blocked by the hydraulic lock 6. The pressure in the hydraulic cylinder 4 is achieved by switching the manifold 7 to the "close" position with the electric motor that controls the actuator pump 8 for hydraulic oil. Further, in the drawing for completeness, there is an oil reservoir 9 and a filter 10.
Vynález je využitefný na pracoviskách, ktoré sa zaoberajú skúšaním hořlavosti a výbušnosti.The invention is applicable to workplaces dealing with flammability and explosivity testing.
