본 고안은 5t 이상 자동차의 엔진에 장착되는 배기브레이크밸브 장치의 내구성을 시험하기 위한 시험기에 관한 것으로 좀더 상세하게는 실제 장착되어 사용되는 조건보다 더 악조건에서 시험을 하고 또 저렴한 경비와 반영구적인 시험기를 제공코자 발명된 것이다.The present invention relates to a tester for testing the durability of the exhaust brake valve device mounted on the engine of a vehicle of 5t or more. More specifically, the test is performed in a worse condition than the actual mounted and used conditions, and the low cost and semi-permanent tester It is intended to provide.
배기브레이크밸브는 5t이상의 자동차의 제동장치 일부분으로서 페달 브레이크에 의해서 작동되는 드럼 라이닝식 제동장치 이외의 제동장치이며 엔진의 배기가스를 차단하여 제동효과를 보조하는 장치이며 자동차에 장착되는 조건이 엔진의 고온 배기열과 배기가스가 통과하는 위치에 설치되어 있으므로 배기가스브레이크밸브 시험은 실제 자동차에 장착된 조건보다 더 가혹한 조건을 만들어 주고 실험하는 것이 바람직하다.Exhaust brake valve is a brake device other than drum lining type brake device which is operated by pedal brake as part of brake device of car over 5t and it is a device to assist the braking effect by blocking the exhaust gas of engine. Because the exhaust gas brake valve test is installed at a position where high temperature exhaust heat and exhaust gas pass, it is desirable to make and test a harsher condition than the actual vehicle mounted condition.
종래 배기브레이크밸브 장치 시험기는 가열장치가 전기 또는 자동차용 연료로서 가열시켜온바 열효율이 떨어져 650℃ 이상 고온 시험이 불가능하며 발생된 열을 밸브에 공급 순환시키는 과정에서 열이 밸브에 도달하지 못하였다. 또 밸브 작동시(닫힘) 연소현상이 잠시 중단되어 온도가 순간적으로 낮아지거나 불연소 현상이 생기게 되어 시험기로서 기능을 다하지 못하고 시험경비가 과다한 것은 물론 시험기의 내열, 내마모, 내구성이 약한 등 다수의 문제점이 있었다.In the conventional exhaust brake valve device tester, since the heating device is heated as fuel for electric or automobile, the thermal efficiency is low, and thus the high temperature test is not possible over 650 ° C., and heat does not reach the valve in the process of supplying and circulating the generated heat to the valve. In addition, when the valve is operated (closed), the combustion phenomenon is interrupted for a while, and the temperature is momentarily lowered or a non-combustion phenomenon occurs. There was a problem.
본 발명은 이와같은 문제점을 해결하기 위해 가스버너를 이용하여 고온 약 900℃까지 가열하고 또 500시간 이상 연속 시험을 가능케 하며 배기관을 두개 형성하고 배기브레이크 밸브를 각각 설치하여 연소 조건을 향상시킴으로서 배기브레이크밸브 두개를 동시에 시험할 수 있게 한 것으로 이하 첨부도면에 의거 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention uses a gas burner to heat up to about 900 ° C. and enables continuous testing for more than 500 hours. The two valves can be tested at the same time and described in detail below according to the accompanying drawings.
즉, 이동이 가능하게 구성된 본체(13)내에 디지탈 온도계(10), 카운터(11), 진공펌프(17) 및 콘트롤박스(12)를 설치하고 상부에 연소관(7)과 배기관(8)을 설치하되 이들 사이에는 두개의 연결관(5)(6)을 구성시켜 각각 밸브(1)(2)를 장착하여 카운터(11)와 연결된 실린더(3)(4)와 결합할 수 있게 구성하고 동 실린더(3)(4)는 진공펌프(17)와 연결하여 실린더(3)(4)에 의해 밸브(1)(2)가 작동되게 구성하며 연결관(5)(6)과 인접한 곳에 온도감지기(9)를 설치하여 디지탈 온도계(10)와 연결하고 연소관(7) 내에는 가스버너(14)와 점화용 전기코일(15)을 장착하며 일측에는 석유노즐(16)을 설치하여 구성된 것이다.That is, the digital thermometer 10, the counter 11, the vacuum pump 17 and the control box 12 are installed in the main body 13, which is configured to be movable, and the combustion pipe 7 and the exhaust pipe 8 are installed on the upper portion thereof. However, between them, two connecting pipes (5) and (6) are constructed so that valves (1) and (2) can be mounted respectively so that they can be combined with the cylinder (3) and (4) connected with the counter (11). (3) (4) is connected to the vacuum pump (17) so that the valves (1) and (2) are operated by the cylinders (3) and (4), and the temperature sensor is located near the connecting pipes (5) and (6). 9) is installed and connected to the digital thermometer 10, the gas burner 14 and the ignition electric coil 15 is mounted in the combustion tube (7) and one side is configured by installing a petroleum nozzle (16).
도면의 미설명부호(20)은 바퀴, (21)은 LPG,LNG 공급관, (22)는 지지간을 표시한 것이다.In the drawing, reference numeral 20 denotes a wheel, 21 denotes an LPG, LNG supply pipe, and 22 denotes a support interval.
이와같이 구성된 본 발명의 작용 및 효과에 대하여 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.
우선 연소관(7)과 배기관(8) 사이의 연결관(5)(6)에 실린더(3)(4)가 연결된 밸브(1)(2)를 각각 장착한 상태에서 LPG 또는 LNG가스를 공급하여 가스버너(14)를 점화시켜 연소관(7) 내에서 연소시키면 배기가스는 두개의 연결관(5)(6), 배기관(8)을 통해 배출되면서 밸브(1)(2)의 작동으로 테스트를 하게 되는데 연소시간 및 가스공급량을 조절해 약 650℃~1000℃ 유지시켜 이는 온도감지기(9)와 디지탈온도계(10)에 의해 항상 온도상태를 알 수 있으므로 필요시 가스공급량을 조절하여 시험조건에 맞는 온도를 유지할 수 있게 되며 진공펌프(17)와 실린더(3)(4)를 작동하여 밸브(1)(2)를 교호로 작동하고 동작 회수는 카운터(11)에 표시되도록 하였다. 그리고 고온에서 내열성, 내마모성 등 내구성을 실제보다 더 악조건에서 시험하게 되며 또 자동차에서와 같은 조건을 주기 위해 석유노즐(16)을 통해 석유를 공급하여 그으름을 발생시킨다. 상기 과정에서 밸브(1)(2)가 교호로 작동하므로 연소시에 방해기 되지 않고 테스트 할 수 있으며 혹시라도 온도저하, 기류이상(열풍, 돌풍) 등으로 연소가 되지 않고 소화가 될시에는 전기코일(15)이 가열되어 있어 계속적인 점화가 가능하게 되므로서 어떠한 조건에서도 신뢰도가 높은 시험이 가능하다.First, LPG or LNG gas is supplied to the connecting pipes 5 and 6 between the combustion pipe 7 and the exhaust pipe 8 and the valves 1 and 2 connected to the cylinders 3 and 4 are respectively mounted. When the gas burner 14 is ignited and combusted in the combustion pipe 7, the exhaust gas is discharged through the two connecting pipes 5 and 6 and the exhaust pipe 8 and tested by the operation of the valves 1 and 2. By adjusting the combustion time and gas supply, it maintains about 650 ℃ ~ 1000 ℃ so that the temperature can always be known by the temperature sensor 9 and the digital thermometer 10. The temperature can be maintained and the valves 1 and 2 are operated alternately by operating the vacuum pump 17 and the cylinders 3 and 4, and the number of operations is displayed on the counter 11. And at high temperature, heat resistance, wear resistance, etc., durability is tested in a worse condition than the actual conditions, and in order to give the same conditions as in the car to supply oil through the petroleum nozzle (16) to generate a soot. In the above process, the valves (1) and (2) operate alternately so that they can be tested without interruption during combustion, and in case of extinguishing without being burned due to temperature drop, abnormal air flow (hot wind, gust), etc. Since the coil 15 is heated to allow continuous ignition, a reliable test can be performed under any conditions.
이상과 같이 LPG, LNG 가스를 이용하여 고온시험과 500시간이상 연속시험이 가능하고 밸브 두개를 교호로 시험할 수 있어 능률을 높일 수 있는 것은 물론 실제 사용조건보다 더 악조건의 실험을 저렴한 가격에 시험이 가능할뿐만 아니라 내열성, 내마모, 내구성이 뛰어난 시험기를 제공할 수 있는 등 많은 장점을 가진 유익한 발명이다.As mentioned above, high temperature test and continuous test for more than 500 hours are possible by using LPG and LNG gas, and two valves can be tested alternately to improve efficiency and to perform experiments at worse price than actual use conditions. Not only is this possible, it is an advantageous invention with many advantages, such as being able to provide a tester with excellent heat resistance, abrasion resistance, and durability.
