본 발명은 스터링기기의 압력조절장치에 관한 것으로 , 특히 별도의 공간 및 부품을 사용하지 않고도 간소한 구성으로 가공성이 향상되고, 부품수가 감소되며, 유로가 짧아지고, 높은 속도에서도 적용가능하며, 작동가스의 유동향에 따라 구멍의 크기나 수를 조절할 수 있어 외부의 설치위치나 면적을 고려하지 않토록 한 스터링기기의 압력조절장치에 관한 것이다.The present invention relates to a pressure regulating device of a sterling machine, and in particular, the workability is improved, the number of parts is reduced, the flow path is shortened, and can be applied even at a high speed without the use of separate spaces and parts. The present invention relates to a pressure regulating device for a sterling device, which can adjust the size or number of holes according to the flow direction of the gas so that an external installation position or area is not taken into account.
일반적인 스터링사이클기기는 제1도에 도시한 바와 같이. 흡열기(1)와, 재생기(2), 방열기(3), 디스플레이서(4)와, 피스톤(5)과, 구동부(6)와, 크랭크케이스(7)등으로 구성되며, 상기 작동체적 내의 압축공간(8)과, 크랭크케이스로 이루어지는 완충공간(9)의 압력차를 최적치로 이루어지기 위해 스터링사이클기기의 바깥에 첵벨브(10)를 설치한다.A typical Stirring cycle machine is shown in FIG. It consists of a heat absorber 1, a regenerator 2, a radiator 3, a displacer 4, a piston 5, a drive unit 6, a crankcase 7, and the like. In order to achieve the optimum pressure difference between the compression space 8 and the buffer space 9 composed of the crankcase, the shock valve 10 is provided outside the Stirling cycle machine.
이와 같이 구성되어 작동되는 스터링사이클기기는 초기에 압축공간(8)과 완충공간(9)이 동일한 압력으로 충진되어 있으나, 작동 중에는 압축과정 중인 고압의 작동가스가 피스톤(5) 씰 사이로 세게 되고, 상기 크랭크케이스(7) 내의 구동부(6)의 운동으로 열이 중가하여 완충공간(8)의 압력도 증가하게 되므로 완충공간(8)도 또 다른 압축, 팽창을 하게 되어 열사이클에 손실을 주게 된다.In the Stirling cycle machine configured and operated as described above, the compression space 8 and the buffer space 9 are initially filled with the same pressure, but during operation, a high-pressure working gas during the compression process is counted between the piston 5 seals, Since the heat is increased by the movement of the drive unit 6 in the crankcase 7, the pressure of the buffer space 8 increases, so that the buffer space 8 is further compressed and expanded, which causes a loss in the thermal cycle. .
따라서, 외부의 별도의 첵 밸브(10)를 설치하여 완충공간(8)이 고압상태가 되면, 작동공간(9)으로 압력을 이동시켜 완충공간(8)의 압력을 낮추어 줌으로서 완충공간(8)에 불필요한 일을 줄일 수 있게 되는 것이다.Therefore, when the shock absorbing space 8 is installed at a high pressure by installing an external check valve 10, the pressure is moved to the operating space 9 to lower the pressure of the shock absorbing space 8. To reduce unnecessary work.
그러나, 상기한 바와 같은 종래의 스털이기기의 압력조절장치는 첵 밸브(10)를 설치하기 위한 위치 및 공간을 확보해야하고,스터링기기의 운전 중 첵 밸브(10)가 파손되어 압력이 샐 우려가 있으며, 부품이 증가되고, 작동가스의 양이 많아질 경우에는 여러 개의 첵 밸브가 필요하게 되는것이며, 기기의 속도가 빠른 경우에는 첵 밸브의 유로가 상대적으로 길기 때문에 압력지연이 발생되는 문제점이 있었다.However, the pressure control device of the conventional sterling machine as described above should secure the position and space for installing the valve 10, and the valve 10 may be damaged during operation of the Stirling device, causing the pressure to leak. If the number of parts is increased and the amount of working gas is increased, several check valves are needed. If the speed of the machine is fast, the pressure delay occurs because the flow path of the check valve is relatively long. there was.
이러한 문제점을 감안하여 안출한 본 발명의 목적은 별도의 공간 및 부품을 사용하지 않고도 간소한 구성으로 가공성이 향상되고,부품수가 감소되며, 유로가 짧아지고, 높은 속도에서도 적용가능하며, 작동가스의 유동량에 따라 구멍의 크기나 수를 조절할 수 있어 외부의 설치위치나 면적을 고려하지 않도록 하려는 것이다.The object of the present invention devised in view of these problems is to improve the workability, reduce the number of parts, shorten the flow path, can be applied even at high speed, without using a separate space and parts, the working gas of The size or number of holes can be adjusted according to the flow rate so that the external installation location or area is not considered.
상기한 바와 같은 본 발명의 목적을 달성하기 위하여, 압축공간과 완충공간을 연결하는 연결공이 다수개 형성된 피스톤과, 상기 피스톤의 상면에 원주방향으로 다수개 형성되어 상기 연결공을 복개하는 원형의 고무판으로 된 밸브와 상기 밸브를 지지고정할 수 있도록 상기 고무판의 내주부를 고정하는 고정쇠를 가지는 고정수단으로 구성한 것을 특징으로 하는 스터링기기의 압력조절장치가 제공된다.In order to achieve the object of the present invention as described above, a piston having a plurality of connection holes connecting the compression space and the buffer space is formed, and a plurality of circular rubber plates formed in the circumferential direction on the upper surface of the piston to cover the connection hole It is provided with a pressure regulating device of the Stirling device, characterized in that consisting of a fixing means having a fixed valve for fixing the valve and the inner peripheral portion of the rubber plate to support the valve.
상기 벨브는 상기 고정수단에 의해 내주부가 고정되어 상기 피스톤이 팽창행정시에만 상기 연결공을 개방하도록 구성되어있다.The valve is configured such that the inner circumference is fixed by the fixing means to open the connection hole only when the piston is in the expansion stroke.
이하. 상기한 바와 같은 본 발명을 첨부도면에 도시한 일실시예에 의거하여 보다 상세히 설명한다.Below. The present invention as described above will be described in more detail based on one embodiment shown in the accompanying drawings.
제2도는 본 발명에 의한 스터링기기의 압력조절장치의 구성도이고, 제3도 및 제4도는 본 발명 장치의 동작을 보인 것으로, 제3는 피스톤 압축시의 상태단면도이고, 제4도는 피스통 팽창시의 상태단면도로서, 제5도는 본 발명에 의한 압축공간의 압력과의 관계그래프로서, 이에 도시한 바와 같이, 본 발명에 의한 스터링기기의 압력저절장치는 압축공간(8)과 완충공간(9)을 연결하는 연결공(11)이 다수개 형성된 피스톤(12)과, 상기 피스톤(12)의 상면으로 설치되어 상기 연결공(11)을 개페하는 밸브와, 상기 밸브를 지지고정하는 고정수단으로 구성한 것이다.2 is a configuration diagram of the pressure regulating device of the Stirling machine according to the present invention, Figures 3 and 4 show the operation of the device of the present invention, Figure 3 is a cross-sectional view of the state of the piston compression, Figure 4 is a piece cylinder 5 is a relation graph of the pressure of the compression space according to the present invention, and as shown in the drawing, the pressure reduction device of the sterling apparatus according to the present invention includes the compression space 8 and the buffer space ( 9) a piston 12 formed with a plurality of connecting holes 11 for connecting the valves, a valve installed at an upper surface of the piston 12 to open the connecting holes 11, and fixing means for supporting the valve. It is made up.
상기 밸브의 피스톤(12)에 원주방향으로 다수개 형성된 연결공(11)을 복개하는 원형의 고무판(13)이고, 상기 고정수단은 강기 고무판(13)의 내주부를 고정하는 고정쇠(14)이다.A circular rubber plate 13 for covering a plurality of connecting holes 11 formed in the circumferential direction on the piston 12 of the valve, and the fixing means is a fastener 14 for fixing the inner circumferential portion of the steel rubber plate 13. .
상기 고정쇠(14)의 상면은 원형의 복개판(15)으로 복개되어 있고, 나사(16)로 상기 고정쇠(14)와 피스톤(12)을 결합한다.The upper surface of the fastener 14 is covered with a circular cover plate 15, and the fastener 14 and the piston 12 are coupled with a screw 16.
이와 같이, 구성되는 본 발명은 피스톤(12)이 상방향으로 이동되어 압축시에는 압력차에 의해 밸브인 고무판(13)이 피스톤(12)의 상면에 밀착되어 씰링역할을 하게 된다.Thus, in the present invention constituted, the piston 12 is moved upwards and when compressed, the rubber plate 13 serving as the valve is in close contact with the upper surface of the piston 12 due to the pressure difference to serve as a sealing role.
또한, 피스톤(12)이 작동가스의 팽창에 의해 하방향으로 이동할 때는 압축공간(8)에서의 작동가스의 압력이 완충공간(9)의 압력보다 클 경우에는 고무판(13)이 닫혀 있게 되지만, 작동가스의 압력이 완충공간(9)의 압력보다 작을 경우(제5도의 I에서 Ⅱ의 구간)에는 고무판(13)이 젖혀지게 되어 연결공(11)이 개방되므로, 완충공간(9)에서 작동공간인 압축공간(8)으로 작동가스가 이동하게 된다.In addition, when the piston 12 moves downward by the expansion of the working gas, the rubber plate 13 is closed when the pressure of the working gas in the compression space (8) is greater than the pressure of the buffer space (9), When the pressure of the working gas is less than the pressure of the buffer space 9 (section I to II of FIG. 5), the rubber plate 13 is flipped over, and thus the connection hole 11 is opened, so that the operating space is operated in the buffer space 9. The working gas moves to the compression space 8, which is a space.
그리하여 상기 완충공간(9)의 최고압력은 압축공간(8)의 최저압력과 거의 동일하게 유지되어 종래의 첵 밸브와 같은 역할을 수행하게 되는 것이다.Thus, the maximum pressure of the buffer space (9) is maintained to be almost the same as the minimum pressure of the compression space (8) to perform the same role as a conventional shock valve.
이상에서 설명한 바와같이, 본 발명에 의한 스터링기기의 압력조절장치는 별도의 공간 및 부품을 사용하지 않고도 간소한 구성으로 가공성이 향상되고, 부품수가 감소되며, 유로가 짧아지고, 높은 속도에서도 적용가능하며, 작동가스의 유동량에 따라 구멍의 크기나 수를 조절할 수 있어 외부의 설치위치나 면적을 고려하지 않아도 되는 효과가 있는 것이다.As described above, the pressure regulating device of the sterling machine according to the present invention can be processed in a simple configuration without using a separate space and parts, the number of parts is reduced, the flow path is shortened, can be applied at high speed And, the size or number of holes can be adjusted according to the flow amount of the working gas has the effect that does not need to consider the external installation location or area.
