본 고안은 트레일러에 설치되는 에어브레이크용 비상릴레이밸브(EMERGENCY RELAY VALVE)에 대한 것이다.The present invention relates to an emergency brake valve (EMERGENCY RELAY VALVE) installed in the trailer.

종래에는 비상릴레이밸브를 트레일러에 설치함에 있어서 이 밸브가 정상적으로 동작중인지를 점검하고저할때에는 운전석에서 브레이크 패달을 밟아 보아야 하므로 점검작업이 매우 번거롭고 불편하였으며, 트레일러와 견인차를 분리시켰을 경우에는 점검을 할 수 없게되는 결점이 있었고, 또 밸브내에 스프링으로 탄발상승되게 내장되는 피스턴은 그 상면중앙에 돌출된 지지측이 벨브커버의 내면에 형성된 지지공내에 끼워져 지지되는데 이 지지측의 외경과 지지공의 내경은 공차가 거의 없도록 제작하였기 때문에 이들이 서로 밀접되게 결합됨에 따라 피스턴의 승강작동이 원활하게 진행되지 못하는등의 결점이 있었다.Conventionally, when installing the emergency relay valve in the trailer, it is very cumbersome and inconvenient to check whether the valve is operating normally, and when you have to step on the brake pedal in the driver's seat, it is very troublesome and inconvenient. The piston, which is built up to spring up in the valve, is supported by the support side projecting in the center of the upper surface of the valve, and is supported in the support hole formed on the inner surface of the valve cover. Since they are manufactured so that they are hardly coupled to each other, there is a drawback that the lifting operation of the piston is not progressed smoothly.

본 고안은 이와 같은 점들을 해결하기 위해 밸브커버의 일측에 에어점검용 체크밸브를 부설하고 피스턴의 지지측은 일측면을 적정폭으로 경사지게 절삭하여 에어밸브의 동작여부를 간편용이하게 점검할 수 있게함은 물론 피스턴의 승강작동이 원활하게 이루어질 수 있도록 고안한 것으로 첨부된 도면에 의거 상술하면 다음과 같다.The present invention provides an air check check valve on one side of the valve cover to solve these points, and the support side of the piston makes it easy to check the operation of the air valve by cutting one side inclined to an appropriate width. Of course, as described above based on the accompanying drawings as designed to facilitate the lifting operation of the piston is as follows.

밸브몸체(1)의 상부에 부착하는 커버(2)의 일측에 이 커버의 내면에 형성된 압력실(4)과 연통되게 결합공(3)을 뚫고 이 결합공에는 에어점검용 체크밸브(5)를 나사식으로 끼워 부설하며, 이 체크밸브의 내부에는 스프링(7)으로 탄발되는 개폐변(6)을 지지관(8)으로 지지되게 결합하여 개폐변(6)의 외단부(6')가 관통공(5')을 통해 외부로 노출되게 하고 피스턴(9)의 상면중앙에 연설한 지지축(10)의 일측면에는 적정폭으로 경사지게 절삭하여 절개면(11)이 경사지게 형성되도로 하여서된 것이다.On one side of the cover (2) attached to the upper part of the valve body (1) drills the coupling hole (3) in communication with the pressure chamber (4) formed on the inner surface of the cover, the check hole (5) for air check Screwed in, and the inside of this check valve is coupled to the opening / closing edge 6 which is supported by the spring 7 to be supported by the support tube 8 so that the outer end 6 'of the opening / closing edge 6 is One side of the support shaft 10 which is exposed to the outside through the through hole (5 ') and addressed to the center of the upper surface of the piston 9 is inclined to be cut at an appropriate width so that the incision surface 11 is formed to be inclined. .

미설명 부호 "12"는 개폐변용 "0"링이며, "13"은 피스턴탄발용 스프링이고, "14"는 커버내면에 형성된 지지공이며, "15"는 에어탱크이고, "16"은 에어호스이며, "17"은 브레이크 챔버이고, "18"은 브레이크 드럼이며, "19"는 브레이크 슈우이고, "20"은 타이어이다.Reference numeral "12" is a "0" ring for opening and closing valve, "13" is a spring for piston shot, "14" is a support hole formed in the inner surface of the cover, "15" is an air tank, "16" is air A hose, "17" is a brake chamber, "18" is a brake drum, "19" is a brake shoe, and "20" is a tire.

이와같이 구성되는 본 고안 비상릴레이 밸브는 트레일러에 설치 사용하는 것으로서, 커버(2)의 내면과 피스턴(9)의 상면사이에 형성되는 압력실(4)과 외부가 연통되게 뚫은 결합공(3)에 에어점검용 체크밸브(5)를 나사식으로 끼워 부설하였기 때문에 트레일러가 견인차에 연결되어 있거나 또는 분리되어있을때를 막론하고 운전석이 아닌 외부에서 체크밸브(5)의 관통공(5')을 통해 노출되는 개폐변(6)의 외단부(6')를 눌러주면 개폐변(6)은 제5도에서 보는 바와 같이 스프링(7)을 압축시키면서 밀려들어가므로 관통공(5')이 열리게 되어 압력실(4)내에 충만되어 있는 에어의 일부가 체크밸브(5)를 통해 외부로 누출이 된다.The emergency relay valve of the present invention, which is constructed as described above, is used to be installed in a trailer, and is connected to a pressure hole 4 formed between the inner surface of the cover 2 and the upper surface of the piston 9 and the coupling hole 3 which communicates with the outside. Since the air check check valve (5) is screwed in and installed, it is exposed through the through hole (5 ') of the check valve (5) from the outside of the driver's seat regardless of whether the trailer is connected to or separated from the tow truck. Press the outer end 6 'of the opening and closing side 6 to be pressed into the opening and closing side 6 while compressing the spring (7) as shown in FIG. A part of the air filled in (4) leaks out through the check valve (5).

따라서 이 체크밸브(5)를 조작하여 에어가 누출되면 비상 릴레이 밸브내에 에어가 충만되어 있는지, 즉 밸브자체가 정상적으로 동작중인지를 간단히 알 수 있게 되는 것이다.Therefore, when the air leaks by operating the check valve 5, it is possible to easily know whether the air is filled in the emergency relay valve, that is, whether the valve itself is normally operating.

한편 피스턴(9)이 상면 중앙 지지축(10)의 일측면은 적정폭으로 절삭하여 절개면(11)이 경사지게 형성하였기 때문에 제2도 및 제3도에서 보는 바와 같이 지지축(10)과 지지공(14) 사이에 공간부(a)가 형성되므로, 지지축(10)과 지지공(14)의 내, 외경 공차가 거의 없게되어도 이 절개면(11)에 의해 형성되는 공간부(a)를 통해 공기가 유통되어 피스턴(9)의 승강작동이 원활하고도 부드럽게 진행이 되는 것이다.On the other hand, since one side of the upper center support shaft 10 of the piston 9 is cut to an appropriate width and the incision surface 11 is formed to be inclined, as shown in FIGS. 2 and 3, the support shaft 10 and the support shaft 10 are supported. Since the space portion a is formed between the holes 14, the space portion a formed by the incision surface 11 even if there is little tolerance between the inner and outer diameters of the support shaft 10 and the support hole 14. Through the air is circulated through the lifting operation of the piston (9) is to proceed smoothly and smoothly.

이와같이 작동되는 본 고안은 밸브의 동작여부를 수시로 간편 용이하게 점검할 수 있어 매우 편리하며, 또 피스턴의 승강작동이 원활하고도 부드럽게 진행되어 그 작용력이 신속 정확하게 브레이크에 전달되는 등 매우 효과적인 고안이다.The present invention operated as described above is very convenient because it can be easily and easily check the operation of the valve from time to time, and is very effective design such that the lifting force of the piston moves smoothly and smoothly so that the action force is quickly and accurately transmitted to the brakes.
