도 8은 본 발명에 따른 보조디스크 슬라이딩형 역류 방지밸브의 밸브체 개방수단의 다른 실시예를 나타낸 단면도이다.(일실시예와 동일한 구성요소에는 동일한 부호를 부여하여 설명의 복잡화를 방지한다.)Figure 8 is a cross-sectional view showing another embodiment of the valve body opening means of the auxiliary disk sliding type non-return valve in accordance with the present invention. (The same components as in the embodiment are given the same reference numerals to avoid the complexity of explanation.)

도시된 바와 같이 이 실시예의 밸브체 개방수단(180)은, 상기 밸브몸체(110) 의 외주연에 형성된 인입구(113) 상에 결합되어지는 하우징(181)과, 상기 하우징(181)에 관통설치되고, 전원의 인가에 의해 작동되는 솔레노이드(186)의 단부에 설치되어 상,하 이동가능한 이송축(182)과, 상기 이송축(182)의 하강 작동에 의해 일단이 상기 밸브체(130)의 일측면을 가압시키도록 하는 상기 밸브몸체(110)의 내부에 형성된 돌출편(114)에 고정되어진 가압축(183)으로 구성된 것이다.As shown, the valve body opening means 180 of this embodiment includes a housing 181 coupled to the inlet 113 formed at the outer circumference of the valve body 110, and a through-hole installed in the housing 181. And one end of the valve body 130, which is installed at an end of the solenoid 186 operated by the application of power, and which is moved up and down and the lower end of the feed shaft 182. It consists of a pressing shaft 183 fixed to the protruding piece 114 formed inside the valve body 110 to press one side.

즉, 장시간 밸브체(130)가 밸브몸체(110)에 폐쇄된 상태에서 펌프의 펌핑에 의해 밸브체(130)를 개방시키기 위해서 전원을 인가하게 되면 솔레노이드(186)가 작동하여 이송축(182)을 하측으로 하강시킴으로 가압축(183)이 전진하여 밸브체(130)를 밀착 해제시키는 것이다.That is, when power is applied to open the valve body 130 by pumping the pump in a state in which the valve body 130 is closed to the valve body 110 for a long time, the solenoid 186 is operated to feed the shaft 182. The pressure shaft 183 is advanced by lowering the pressure downward to release the valve body 130 in close contact.

이때 전원은 별도의 직류 전원 또는 교류 전원 등 어느 것을 사용해도 무방하다.At this time, any one of a separate DC power supply or AC power supply may be used.

상기와 같이 구성된 보조 디스크 슬라이딩형 역류 방지밸브는, 일측에서 타측으로 유체가 이송되는 관로상에 설치하게 되고, 도시되지 않은 펌프 등의 펌핑 압력이 작용하게 되면 상기 회전축(120)을 중심으로 상기 밸브체(130)가 유체의 압력에 의해 개방되는데, 이때 밸브체(130)에 형성된 포트(131)를 폐쇄하고 있던 보조밸브체(160)가 보조축(171)을 중심으로 개방된다.The auxiliary disk sliding type non-return valve configured as described above is installed on a pipeline through which fluid is transferred from one side to the other side, and when a pumping pressure such as a pump (not shown) is applied, the valve is rotated about the rotation shaft 120. The sieve 130 is opened by the pressure of the fluid. At this time, the auxiliary valve body 160 closing the port 131 formed in the valve body 130 is opened around the auxiliary shaft 171.

또한, 상기 밸브체(130)가 개방되면서 상기 무게추(140)도 상측으로 이동됨과 아울러 댐퍼(150)의 실린더 로드(151)도 전진되면서 유로를 개방시키게 된다.In addition, as the valve body 130 is opened, the weight 140 is also moved upward, and the cylinder rod 151 of the damper 150 is advanced to open the flow path.

그리고, 관로 상에 펌프 등의 펌핑 압력이 해제되면, 상기 밸브체(130)는 회전축(120)을 중심으로 자중에 의해 회전되면서 유로(111)를 폐쇄하게 되고, 이때 무게추(140)에 의해 밸브체(130)가 더 원활히 폐쇄된다.When the pumping pressure of the pump or the like is released on the conduit, the valve body 130 rotates by its own weight about the rotation shaft 120 to close the flow path 111. In this case, the weight 140 The valve body 130 closes more smoothly.

또한, 상기 밸브체(130)가 폐쇄되면서 보조축(171)에 아암(172)과 링크부재(173)로 연동된 보조밸브체(160)가 가이드부(174)를 따라 포트를 폐쇄시키게 된다.In addition, as the valve body 130 is closed, the auxiliary valve body 160 linked with the arm 172 and the link member 173 to the auxiliary shaft 171 closes the port along the guide portion 174.

상기와 같이 동작되는 보조디스크 슬라이딩 역류방지밸브를 장시간 밸브체(130)가 작동하지 않고 폐쇄된 상태를 유지하게 되면 밸브체(130)의 시트링(132)과 밸브몸체(110)의 시트(112) 사이가 밀착이 되어 펌프 등의 펌핑 압력에도 밸브체(130)가 개방되지 않게 되는데, 이때 본 발명의 밸브체 개방수단(180)을 동작시키게 된다.When the auxiliary disk sliding check valve is operated as described above and the valve body 130 remains closed without operating for a long time, the seat ring 132 of the valve body 130 and the seat 112 of the valve body 110 are closed. ) Is in close contact with each other so that the valve body 130 is not opened even at a pumping pressure such as a pump. At this time, the valve body opening means 180 of the present invention is operated.

즉, 핸들(184)을 회전시켜 이송축(182)에 형성된 나사산(182a)을 따라 이송축(182)이 하강하거나, 전원을 인가하여 솔레노이드(186)를 동작시키게 되면 이송축(182)이 하강하게 되고, 상기 이송축(182)의 경사면(S1)에 접면되어진 가압축(183)의 경사면(S2)에 의해 가압축(183)이 전진하면서 밸브체(130)를 가압시켜 밀착되어진 시트링(132)을 밸브몸체(110)의 시트(112)에서 이격시키게 된다.That is, the feed shaft 182 is lowered when the feed shaft 182 is lowered along the thread 182a formed on the feed shaft 182 by rotating the handle 184 or when the solenoid 186 is operated by applying power. The pressing ring 183 is advanced by the inclined surface S2 of the pressing shaft 183, which is in contact with the inclined surface S1 of the feed shaft 182, and presses the valve body 130 to close the seating ring ( 132 is spaced apart from the seat 112 of the valve body (110).

상기와 같이 장시간 밀착되어진 시트링(132)을 밸브몸체(110)의 시트(112)에서 이격시킨 상태에서는 펌프 등의 펌핑 압력에 의해 용이하게 밸브체(130)가 개방되어 유로를 개방시키게 된다.In the state in which the seat ring 132 that is in close contact with the long time as described above is separated from the seat 112 of the valve body 110, the valve body 130 is easily opened by the pumping pressure such as a pump to open the flow path.
