Description

자동차의 엘피지 충전성능 향상구조{LPG inflation performance increasing structure of vehicles}LPG inflation performance increasing structure of vehicles}

본 발명은 자동차의 엘피지(LPG ; liquefied petroleum gas) 충전성능 향상구조에 관한 것으로, 특히 여름철에 엘피지의 충전이 원활히 이루어질 수 있도록 된 자동차의 엘피지 충전성능 향상구조에 관한 것이다.The present invention relates to a structure for improving the performance of filling liquefied petroleum gas (LPG) of an automobile, and more particularly, to an structure for improving the filling performance of an automobile in order to be able to smoothly fill an Elpgi during summer.

최근 봄베(bombe)의 탑재와 연료보급의 문제에도 불구하고 저렴한 가격 때문에 택시나 영업용 차량을 중심으로 엘피지를 연료로써 사용하는 차량이 늘고 있다.Recently, despite the problem of bombe and refueling, due to the low price, the number of vehicles using lpuji as a fuel is increasing mainly in taxis and commercial vehicles.

기술된 바와 같이 엘피지를 연료로 사용하는 차량에는 가솔린이나 디젤 차량의 연료탱크에 해당하는 봄베가 트렁크의 내부에 설치되어 있으며, 이 봄베에 엘피지를 충전하기 위한 충전관로의 구조는 도 1에 도시된 바와 같다.As described above, in a vehicle using Elpium as a fuel, a cylinder corresponding to a fuel tank of a gasoline or diesel vehicle is installed in the trunk, and the structure of a charging conduit for charging the Elpji in the cylinder is shown in FIG. As shown.

즉, 트렁크의 내부에 봄베(1)가 설치되고, 이 봄베(1)의 일측에 밸브핸들(2a)를 갖춘 충전밸브(2)가 설치되며, 이 충전밸브(2)에는 조임너트(3)를 매개로 금속파이프(4)가 연결되며, 이 금속파이프(4)에 고무호스(5)가 연결되고, 이 고무호스(5)에 다시 차체패널(8)의 필라리드(9) 설치부위까지 연장되는 금속파이프(6)가 연결되며, 이 금속파이프(6)의 단부에는 충전소의 충전장치가 연결될 수 있는 충전구(7)가 설치되는 구조로 이루어져 있다.That is, a cylinder 1 is installed inside the trunk, and a filling valve 2 having a valve handle 2a is installed at one side of the cylinder 1, and the tightening nut 3 is provided at the filling valve 2. The metal pipe (4) is connected via the medium, and the rubber hose (5) is connected to the metal pipe (4), and the rubber hose (5) is connected to the mounting portion of the pillar lid (9) of the body panel (8) again. An extended metal pipe 6 is connected, and the end of the metal pipe 6 has a structure in which a charging hole 7 to which a charging device of a charging station is connected is installed.

여기서, 상기 충전구(7)는 일종의 체크밸브형식으로 구성되어 있어서 엘피지 충전시에는 원활히 엘피지가 주입되고 충전 완료시에는 리턴스프링에 의해 자동적으로 차단되어 충전관로상에 남아 있는 엘피지가 외부로 누출되지 않도록 되어 있다.Here, the filling port (7) is composed of a kind of check valve type so that the vellum is smoothly injected during the filling of the vellum and automatically shut off by the return spring when the filling is completed so that the remaining vellum on the filling pipe passage does not leak to the outside It is.

따라서, 충전소에서 충전장치를 상기 충전구(7)에 연결하고, 밸브핸들(2a)을 돌려 충전밸브(2)를 연뒤, 엘피지를 주입하면 엘피지는 상기 금속파이프(6)→고무호스(5)→금속파이프(4)→충전밸브(2)를 거쳐 봄베(1)안에 충전되며, 충전완료후에는 밸브핸들(2a)을 잠그고 충전구(7)로부터 충전장치를 분리시키면 엘피지의 충전작업이 종료된다.Therefore, at the filling station, the filling device is connected to the filling hole 7, the valve handle 2a is turned to open the filling valve 2, and then the Elpji is injected into the metal pipe 6 to the rubber hose 5. → Filled in cylinder 1 via metal pipe (4) → filling valve (2). After filling is complete, lock the valve handle (2a) and remove the filling device from the filling port (7) to complete the filling process do.

한편, 엘피지를 연료로 사용하는 차량에서는 초기 시동시 냉각수 온도가 15℃ 이하일 경우 기체상태의 연료를 사용하여 시동을 하고, 이후 냉각수온이 15℃이상으로 상승하면 액체상태의 연료를 사용하여 엔진을 가동한다.On the other hand, in the case of vehicles using Elpium as a fuel, when the coolant temperature is 15 ° C. or lower at the initial start-up, the engine is started using gaseous fuel, and when the coolant temperature rises to 15 ° C. or higher, the engine is operated using liquid fuel. Operate.

따라서, 여름이 아닌 계절에는 초기 시동시에 봄베(1)의 상부에 모여 있는 기체상태의 연료를 일정하게 사용하게 되므로 봄베(1) 내부의 압력을 낮춰주는 효과가 발생하나, 여름과 같이 더운 날씨에는 시동시 냉각수의 온도가 이미 15℃이상인 경우가 대부분이므로 처음부터 액체상태의 연료만을 사용하기 때문에 기체상태의 연료가 봄베(1) 내부에 누적되어 봄베(1)의 내압이 상승되는 현상이 발생한다.Therefore, in the non-summer season, the gaseous fuel collected at the upper part of the cylinder 1 is used at the time of initial start-up, thereby reducing the pressure inside the cylinder 1, but it is hot in summer. Since the temperature of the coolant is more than 15 ℃ at the time of start-up, only liquid fuel is used from the beginning, so gaseous fuel accumulates inside the cylinder 1, causing the internal pressure of the cylinder 1 to rise. do.

이와 같이 상승된 봄베(1)내부의 압력이 5kgf/cm2이상의 고압이 되면 충전소에서 엘피지를 충전할 때 충전효율이 저하되어 충전에 장시간이 소모되므로 운전자나 충전소 모두에게 불편을 주게 되는 문제점이 있었다.When the pressure inside the cylinder 1 rises above 5kg f / cm 2 , the charging efficiency is lowered when charging the LLP at the charging station, which consumes a long time for charging, which causes inconvenience to both the driver and the charging station. there was.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 여름철 기온 상승으로 봄베의 내부에 누적된 기체상태의 엘피지를 외부로 배출시켜줄 수 있게 됨으로써 봄베의 내부압력을 낮춰 주어 외부로부터의 엘피지 충전이 용이하게 이루어질 수 있도록 된 자동차의 엘피지 충전성능 향상구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by lowering the internal pressure of the bomb to be discharged to the outside as the gas temperature increases the temperature in the summer to the outside of the bomb, the filling of the vellum from the outside It is an object of the present invention to provide a structure for improving the charging performance of the ELP of the vehicle that can be easily made.

상기와 같은 목적을 달성하기 위한 본 발명은, 봄베에 설치된 충전밸브의 밸브바디에 관통구멍이 형성되고, 이 관통구멍을 개폐하는 퍼지스템(purge stem)이 구비된 구조로 이루어진다.The present invention for achieving the above object is made of a structure in which a through hole is formed in a valve body of a filling valve installed in a cylinder, and a purge stem for opening and closing the through hole is provided.

따라서, 봄베 내압 상승시 상기 퍼지스템을 개방하여 봄베 내부의 가스를 일부 배출시킴으로써 압력을 낮출 수 있게 되므로 엘피지의 충전이 용이하게 이루어진다.Therefore, when the internal pressure of the cylinder rises, the pressure can be lowered by opening the purge system to discharge some of the gas inside the cylinder, thereby easily filling the LPG.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 2는 본 발명에 따른 엘피지 충전성능 향상구조가 적용된 봄베의 충전밸브 측면도와 이의 정면도로서, 본 발명은 충전밸브(2)의 밸브바디(2b) 상부에 가스를 배출할 수 있는 퍼지스템(10)이 설치된 구조로 이루어진다.2 is a side view and a front view of a charging valve of a bomb applied with the LPG charging performance improving structure according to the present invention, the present invention is a purge system 10 capable of discharging gas on the valve body (2b) of the filling valve (2) ) Is installed.

도 3은 상기 퍼지스템(10)이 설치된 부위의 단면도로서, 상기 퍼지스템(10)은 원형의 헤드(10a)와 이 헤드(10a)의 하부에 일체로 연장성형된 바디(10c)와, 이 바디(10c)의 하부에 고정된 고무재질의 밸브판(10d)으로 이루어지며, 상기 헤드(10a)의 외주면에는 수나사(10b)가 형성되고 상부면에는 일자형 또는 십자형의홈(10e)이 형성된다.3 is a cross-sectional view of a portion where the purge system 10 is installed. The purge system 10 includes a circular head 10a and a body 10c integrally formed under the head 10a. It is made of a rubber valve plate 10d fixed to the lower part of the body (10c), the outer peripheral surface of the head (10a) is formed with a male screw (10b) and the upper surface is formed with a straight or cross-shaped groove (10e). .

한편, 상기 퍼지스템(10)이 설치되는 충전밸브(2)의 밸브바디(2b)에는 원통형 공간(2c)이 형성되고, 이 원통형 공간(2c)과 밸브바디 내부공간(2d)을 관통하는 관통구멍(2e)이 형성되며, 이 관통구멍(2e)의 입구부분에는 상방으로 돌출성형된 돌출부(2f)가 형성되고, 상기 원통형 공간(2c)의 내주면에는 암나사(2g)가 형성된다.Meanwhile, a cylindrical space 2c is formed in the valve body 2b of the filling valve 2 on which the purge system 10 is installed, and penetrates through the cylindrical space 2c and the valve body internal space 2d. A hole 2e is formed, and an inlet portion of the through hole 2e is formed with a protrusion 2f protruding upward, and a female screw 2g is formed on the inner circumferential surface of the cylindrical space 2c.

따라서, 상기 원통형 공간(2c)의 암나사(2g)에 헤드(10a)의 수나사(10b)가 나사체결됨으로써 퍼지스템(10)이 밸브바디(2b)에 장착되고, 장착상태에서 드라이버와 같은 공구를 사용하여 헤드(10a)를 시계방향으로 돌려주면 밸브판(10d)이 하강하여 돌출부(2f)에 밀착됨으로써 관통구멍(2e)이 막혀져 봄베(1)는 밀폐상태에 있게 된다.Accordingly, the male screw 10b of the head 10a is screwed into the female screw 2g of the cylindrical space 2c so that the purge stem 10 is mounted on the valve body 2b, and a tool such as a driver is mounted in the mounted state. When the head 10a is turned clockwise, the valve plate 10d descends and comes into close contact with the protruding portion 2f so that the through hole 2e is blocked so that the cylinder 1 is in a closed state.

그러므로, 봄베(1)의 내압이 정상일 때는 상기 퍼지스템(10)을 조작할 필요 없이 종래와 동일한 방식으로 밸브핸들(2a)만을 열어 충전작업을 실시하면 되고, 여름철과 같이 봄베(1)의 내압이 상승하여 엘피지의 충전이 원활히 이루어지지 않을때는 상기 헤드(10a)를 시계 반대방향으로 풀어 밸브판(10d)을 돌출부(2f)로부터 이격시키면 관통구멍(2e)이 개구됨으로써 봄베(1)내부의 가스가 외부로 배출되어 압력이 저하되고, 이에 따라 내압에 따른 저항이 제거되므로 엘피지의 충전이 원활히 이루어질 수 있게 된다.Therefore, when the internal pressure of the cylinder 1 is normal, it is not necessary to operate the purge system 10, and only the valve handle 2a can be opened to perform the filling operation in the same manner as in the prior art, and the internal pressure of the cylinder 1 may be as in summer. In this case, when the elbow is not fully charged, the head 10a is released in the counterclockwise direction and the valve plate 10d is separated from the protrusion 2f so that the through hole 2e is opened. Since the gas is discharged to the outside to lower the pressure, and thus the resistance according to the internal pressure is removed, it is possible to smoothly charge the LP.

이상 설명한 바와 같이 본 발명에 따르면, 여름철에 봄베의 내압이 상승하여엘피지의 충전이 원활히 이루어지지 않을 때 봄베 내의 가스를 외부로 배출하여 봄베 내압을 낮출 수 있게 됨으로써 엘피지 충전효율이 향상되어 보다 신속하게 충전작업을 수행할 수 있게 되는 장점이 있다.As described above, according to the present invention, when the internal pressure of the bomb rises during the summer season, when the filling of the lpgi is not performed smoothly, the gas inside the cylinder can be discharged to the outside to lower the cylinder pressure, thereby improving the lpgi filling efficiency more quickly. There is an advantage to be able to perform the filling operation.
