The lifting member 170 to be described later is in close contact with the notch 16.

상기 승강체(170)는 제1 구조물(10)의 내측에 배치되며, 압력에 상응하여 동작되도록 구성되어 있다. 상기 승강체(170)는 불소수지나 EPDM(Ethylene Prophlene Diene Monomer) 등의 수지제로 형성하여 소정 압력에 대하여 부상할 수 있도록 구성하였다.The lifting body 170 is disposed inside the first structure 10 and is configured to operate in response to pressure. The lifting member 170 is formed of a resin such as fluorine resin or EPDM (Ethylene Propylene Diene Monomer) and configured to float to a predetermined pressure.

상기 안내부재(180)는 도 5 내지 도 7에 도시된 바와 같이, 승강체(170)의 상부에 배치되며, 승강체(170)의 이동을 안내하는 역할을 수행하게 된다. 그리고, 안내부재(180)는 제1 구조물(40)의 내측에 형성된 요홈부(44)에 끼워지게 된다.As illustrated in FIGS. 5 to 7, the guide member 180 is disposed above the lifting body 170 and serves to guide the movement of the lifting body 170. In addition, the guide member 180 is fitted into the recess 44 formed inside the first structure 40.

상기 안내부재(180)는 판스프링(182)와, 상기 판스프링(182)의 중앙에 배치되며 승강체(170)의 일부를 수용하는 수용부(184)와, 상기 수용부에 간격을 두고 배치되는 채널부(186)로 이루어지게 된다.The guide member 180 is disposed in the leaf spring 182, the center of the leaf spring 182 and the receiving portion 184 for receiving a portion of the lifting body 170, and spaced apart from the receiving portion Channel portion 186 is made.

상기 판스프링(182)은 플레이트 형태로 이루어지고, 제1 구조물(40)의 내측에 형성된 요홈부(44)에 끼워지게 된다. 그리고, 상기 판스프링(182)은 소정 압력에 상응하여 적절한 변형이 일어나도록 사용자가 그 개수를 선택하게 된다.The leaf spring 182 is formed in a plate shape and is fitted into the recess 44 formed inside the first structure 40. In addition, the leaf spring 182 is selected by the user so that the appropriate deformation occurs in accordance with the predetermined pressure.

상기 수용부(184)는 중공 형태로 이루어지고, 내측에 승강체(170)의 일부를 수용함과 동시에 미세한 압력으로 승강체(170)를 누름에 의해 승강체(170)와 접촉면인 노치부(16)가 긴밀하게 접촉할 수 있게 된다.

본 발명의 일 실시예에 따른 에너지 저장장치용 안전변(100)에 대한 동작을 설명하면 다음과 같다.Referring to the operation of the safety valve 100 for an energy storage device according to an embodiment of the present invention.

먼저, 에너지 저장장치용 안전변(100)은 에너지 저장장치(5)에서 압력이 일정한 경우나 압력이 낮은 경우에는 도 1에 도시된 바와 같이, 한 쌍의 탄성체(70)가 서로 맞물려져 있게 된다. First, the safety valve 100 for the energy storage device, when the pressure is constant or the pressure is low in the energy storage device 5, as shown in Figure 1, a pair of elastic bodies 70 are engaged with each other.

그러나, 안전변(100)내의 압력이 상승하게 되면, 도 2에 도시된 바와 같이, 한 쌍의 탄성체(70)는 자체 변형력에 의해 틈새(A)가 벌어지게 된다. 즉, 한 쌍의 탄성체(70)가 벌어지게 되면, 에너지 저장장치(5)로부터 가스가 홀(10)을 통과하여 틈새(A)를 경유하여 분출구(20)로 배출되게 된다.However, when the pressure in the safety valve 100 rises, as shown in FIG. 2, the pair of elastic bodies 70 have a gap A due to their deformation force. That is, when the pair of elastic bodies 70 are opened, the gas passes through the hole 10 from the energy storage device 5 and is discharged to the jet port 20 via the gap A.

한편, 소정 가스를 배출하게 되면 안전변(100)내의 압력이 하강하게 되고, 한 쌍의 탄성체(70)는 도 2에 도시된 상태로부터 도 1에 도시된 바와 같은 상태로 되게 된다. 즉, 상기 한 쌍의 탄성체(70)는 압력이 하강하게 되면 탄성체의 자체 복원력에 의해 수축되게 된다. 이때, 한 쌍의 탄성체(70)가 복원되면 틈새(A)는 폐쇄되게 된다. On the other hand, when the predetermined gas is discharged, the pressure in the safety valve 100 is lowered, and the pair of elastic bodies 70 are in a state as shown in FIG. 1 from the state shown in FIG. 2. That is, the pair of elastic bodies 70 are contracted by the self restoring force of the elastic bodies when the pressure drops. At this time, when the pair of elastic bodies 70 is restored, the gap A is closed.

이와 같이 본 발명의 에너지 저장장치용 안전변(100)은 한 쌍의 탄성체(70)와 같은 간단한 구조를 적용하여 안전변의 부피를 최소화하면서 에너지 저장장치로부터 발생되는 가스를 원활히 배출할 수 있다. As described above, the safety valve 100 for the energy storage device of the present invention may smoothly discharge the gas generated from the energy storage device while minimizing the volume of the safety valve by applying a simple structure such as a pair of elastic bodies 70.

본 발명의 다른 실시예에 따른 에너지 저장장치용 안전변(200)에 대한 동작을 설명하면 다음과 같다.Referring to the operation of the safety valve 200 for an energy storage device according to another embodiment of the present invention.

Will be.

그러나, 안전변(200)내의 압력이 상승하게 되면, 도 6에 도시된 바와 같이, 승강체(170)가 상승하면서 틈새(B)가 벌어지게 된다. 즉, 상기 승강체(170)가 상승하게 되면, 에너지 저장장치(5)로부터 가스가 홀(10)을 통과하여 틈새(B)를 경유하여 분출구(20)로 배출되게 된다.However, when the pressure in the safety valve 200 rises, as shown in Figure 6, the lifting body 170 is raised while the gap (B) is opened. That is, when the lifting body 170 rises, the gas passes through the hole 10 from the energy storage device 5 and is discharged to the jet port 20 via the gap B.

한편, 소정 가스를 배출하게 되면 안전변(200)내의 압력이 하강하게 되고, 승강체(170)는 도 6에 도시된 상태로부터 도 5에 도시된 바와 같은 상태로 되게 된다. 즉, 상기 승강체(170)는 압력이 하강하게 되면 원래의 위치로 이동하게 된다. 이때, 승강체(170)가 하강되면 틈새(B)는 폐쇄되게 된다.On the other hand, when the predetermined gas is discharged, the pressure in the safety valve 200 is lowered, and the lifting body 170 is in a state as shown in FIG. 5 from the state shown in FIG. 6. That is, the lifting body 170 is moved to its original position when the pressure is lowered. At this time, when the lifting member 170 is lowered, the gap B is closed.

이와 같이 본 발명의 에너지 저장장치용 안전변(200)은 승강체(170)와 같은 간단한 구조를 적용하여 안전변의 부피를 최소화하면서 에너지 저장장치로부터 발생되는 가스를 원활히 배출할 수 있다. As described above, the safety valve 200 for the energy storage device of the present invention may smoothly discharge the gas generated from the energy storage device while minimizing the volume of the safety valve by applying a simple structure such as the lifting body 170.
