Description

유체 및 기체용 단동(원웨이)밸브{omitted}Single-way (one-way) valves for fluids and gases

본 발명은 유체 및 기체용 단동(One way) 밸브에 관한 것으로, 특히 직선운동식으로 당기거나 밀어서, 밸브 출구를 개폐시키지 않고, 고정 자석의 회전작용을 이용하여 밸브 출구를 개폐시키므로서, 전기도 절약되고, 긴밀성과 내구성이 뛰어나도록 한 유체 및 기체용 단동(원 웨이) 밸브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one way valve for fluids and gases, and in particular, by drawing or pushing in a linear motion, without opening and closing the valve outlet, by opening and closing the valve outlet using the rotational action of the fixed magnet, A single-acting (one-way) valve for fluids and gases, which is saved, and has excellent tightness and durability.

종래에는, 출구를 막고있던 밸브를, 솔레노이드 밸브식의 직전운동으로, 당기거나 밀어서 개폐 시키므로서, 출구를 열때는 밸브를 계속 당기는 상태를 유지해야 하므로 전원을 계속 사용해야 하고, 출구를 닫을때는 밸브를 스프링 힘으로 밀도록 되어있어, 내구성이 떨어지고, 전기 소모량이 증대하며, 일반적으로 30분 이상 작동시, 코일이 탄다든지, 스프링의 탄력성이 저하된다든지 하여 내구성이 떨어지고, 밸브 수명이 단축되는 등 많은 문제점이 있었다.Conventionally, the valve blocking the outlet is pulled or pushed to open or close the solenoid valve type by the immediate movement, so that the valve must be kept pulling when opening the outlet, and the valve must be used when closing the outlet. It is pushed by the spring force, so durability is low, electricity consumption is increased, and in general, when it is operated for more than 30 minutes, the coil is burned or the spring elasticity is decreased, so durability is decreased and valve life is shortened. There was a problem.

본 발명의 상기한 종래 기술이 갖고있는 문제점을 해소코자 창출한 것으로, 밸브 출구의 개폐를 전원 인가시 1회만 회전작동하되, 180°회전하여 출구를 개폐시키고, 180°회전한 상태를 전원 공급없이 유지되다가, 다시 전원이 인가되면 180°회전하여 원위치로 복귀하도록 하므로서, 계속 사용시에도 밸브 구동을 위한 전원 공급이 계속되지 않아도 되므로, 전력 소모량이 대량절감되고, 스프링의 힘으로 밀어서 밸브 캡으로 출구를 막고 긴밀성을 유지하는 것이 아니므로, 밸브캡의 회전위치에 따라 출구가 개폐되므로, 긴밀성이 뛰어나고 내구성이 증진되며, 기기 수명이 반영구적이 되어, 기기 성능과 품질을 향상 시키고, 유체나 기체의 누수를 방지하는 안전성을 증진 시키는데 그 목적이 있다.To solve the problems of the prior art of the present invention to solve the problem, the opening and closing of the valve outlet is only one rotational operation when the power is applied, rotates 180 ° to open and close the outlet, rotated 180 ° state without power supply When the power is applied again, it is rotated 180 ° to return to the original position, so that the power supply for the valve driving does not need to be continued even in the continuous use, so that the power consumption is greatly reduced, and the spring is pushed out by the force of the valve cap.

이와 같이 구성된 본 발명의 작용은 다음과 같다,The operation of the present invention configured as described above is as follows,

콘넥터(10)를 통해 전원을 인가 시키면, 전기코일(8)(9)측에 자석극(N.S극)이 형성하게 되고, 고정자석(6)에도 같은 자석극(N.S극)이 생겨서 상호 밀게 되므로 고정자석(6)이 회전하다가, 도2와 같이 상호의 자석극이 반대로 되는 위치 즉 180°회전하면 상호 당기게 되므로 정지하게 되고. 이때 스톱퍼(16)(17)는 상호 접촉되어 정확한 위치를 유지하게 해준다.When power is applied through the connector 10, a magnet pole (NS pole) is formed on the side of the electric coils (8) and (9), and the same magnet pole (NS pole) is formed on the stator magnet 6 and is pushed together. While the stationary magnet 6 rotates, as shown in FIG. The stoppers 16 and 17 are then in contact with each other to maintain the correct position.

비 사용시에도, 다시 전원을 한번 인가해주면, 반대방향으로 다시180°회전한후 정지 하게 된다, 따라서 전원을 한번 인가 한후 전원 공급을 차단해도 180°회전 상태를 유지하기 때문에 전원 소모량이 크게 절감된다, 또한 출구(11)(12)측에 밸브 캡(22)의 저면에 형성시킨 고무패킹(18)의 열림면(19)이 위치 하는가 닫힘면(20)이 위치하는가에 따라 출구(11)(12)가 열리거나 닫히게 되므로 개폐 상태가 정확하고 긴밀하며,Even when not in use, once the power is applied again, the motor rotates 180 ° in the opposite direction and stops. Therefore, the power consumption is greatly reduced because it maintains the 180 ° rotation even after the power is turned off. In addition, depending on whether the opening face 19 or the closing face 20 of the rubber packing 18 formed on the bottom face of the valve cap 22 is positioned on the outlet 11 and 12 side, the outlet 11 and 12 are located. ) Open or close, so the open and close state is accurate and tight,

종래 스프링(4)이 미는 힘으로 닫히던 직선운동식 밸브의 긴밀성과 내구성의 빈약성을 극복 할수있게 된다.Conventional springs (4) can overcome the tightness and poor durability of the linear valve closed by the pushing force.

또한 밸브캡(22)저면에 형성시킨 고무패킹(18)의 열림면(19)과 닫힘면(18)의 형상 변화에 따라 1번출구(11)와 2번출구(12)가 동시에 열리거나, 교대로 개폐되도록 할수있게 된다.In addition, the first exit 11 and the second exit 12 are simultaneously opened or alternately in accordance with the shape change of the opening surface 19 and the closing surface 18 of the rubber packing 18 formed on the bottom of the valve cap 22. It can be opened and closed.

이상에서 살펴본 바와 같이, 본 발명은 구성이 간단하면서, 밸브의 핵심인 긴밀성과 내구성을 증진시키고 작동상태가 정확하며, 전력소모량을 대량 절감시키고, 장기간 작동시 에도 코일이 탄다든지, 스프링의 탄성력을 약화시켜 긴밀성이 둔화 되고, 누수현상이 발생하는것 등을 방지 시키고, 이로인해 품질을 향상시키고, 장기간 사용에도 안전하며, 내구성을 증진 시킨 효과 가 있는 대단히 유용한 발명인 것이다.As described above, the present invention is simple in configuration, improves the tightness and durability of the core of the valve, the operation state is accurate, the power consumption is reduced a lot, the coil burns or the elastic force of the spring even during long-term operation It is a very useful invention that has the effect of weakening the tightness, preventing the occurrence of leakage phenomenon, thereby improving the quality, safe for long-term use, and improving durability.
