이와 같이 된 본 발명의 작동을 설명하면 다음과 같다.The operation of the present invention will now be described.

디스크(4)의 디스크시트(5)가 밸브본체(1)의 보디시트(2)에 밀착되어 도7과 같이 완전히 닫힌 상태에서는 디스크개폐축(6)의 사각부(6A)에 사각구멍(150)이 끼워진 회전판(15)의 긴슬라이더(15A)와 짧은슬라이더(15B)는 베이스프레이트(14)의 슬라이더삽입홈(140)에 놓여진 상태로 되는데 이때 짧은 슬라이더(15B)는 슬라이더삽입홈(140)의 외측으로 노출되지 않고 긴슬라이더(15A)는 슬라이더삽입홈(140)의 외측으로 노출된 상태로 되며 웜(9)과 이맞춤되어 회전되는 웜휠(7)에 형성된 걸림돌기(7A)는 도8에 도시된 바와 같이 L1선상에 놓여진 상태로 된다.When the disk sheet 5 of the disk 4 is in close contact with the body sheet 2 of the valve body 1 and is completely closed as shown in Fig. 7, the square hole 6A of the disk opening / The long slider 15A and the short slider 15B of the rotary plate 15 in which the slider 15B is inserted are placed in the slider insertion groove 140 of the base plate 14. The short slider 15B is inserted into the slider insertion groove 140, The long slider 15A is exposed to the outside of the slider inserting groove 140 and the engaging protrusion 7A formed in the worm wheel 7 rotated in alignment with the worm 9 is moved to the position shown in Fig. As shown in Fig.

상기의 상태에서 디스크(4)를 회전시켜 열고자 할 때는 핸들(10)과 웜(9)에 의하여 웜휠(7)을 시계방향으로 회전시켜 열게 되는데 웜휠(7)의 걸림돌기(7A)가 도8의 L1선상에서 L2선상까지 회전되는 동안에는 회전판(15)의 짧은 슬라이더(15B)는 걸림돌기(7A)에 걸려지지 않기 때문에 디스크개폐축(6)의 사각부(6A)에 사각구멍(150)이 끼워진 회전판(15)은 회전되지 않으며 디스크개폐축(6)도 회전되지 않는다. 이에 따라 웜휠(7)의 걸림돌기(7A)가 L1선상에서 L2선상으로 회전될 시에는 디스크개폐축(6)은 회전되지 않는 반면 도6에 도시된 바와 같이 회전되는 웜휠(7)과 사각키(17)로 고정된 슬리브(16)의 회전에 의하여 슬리브(16)에 나사부(6B)가 나사 맞춤된 디스크개폐축(6)은 도7의 백선화살표방향인 하방으로 직선이동하게 된다.The worm wheel 7 is rotated in the clockwise direction by the handle 10 and the worm 9 so that the worm wheel 7 is rotated in the clockwise direction. The short slider 15B of the rotary plate 15 is not caught by the engaging projection 7A while the rotary shaft 15 is rotated up to the L2 line on the L1 line of the disk opening / closing shaft 6. Therefore, the rectangular hole 6OA of the disk opening / The disk 15 is not rotated and the disk opening / closing shaft 6 is not rotated. Accordingly, when the latching protrusion 7A of the worm wheel 7 is rotated in the L2 direction on the L1 line, the disk opening / closing shaft 6 is not rotated, while the worm wheel 7 rotated as shown in Fig. The disk opening and closing shaft 6 in which the screw portion 6B is screwed to the sleeve 16 by the rotation of the sleeve 16 fixed by the arm 17 moves linearly downward in the direction indicated by the white line in Fig.

이에 따라 디스크개폐축(6)의 경사축(6')에 축받이(4')의 축끼움구멍(401)과 축홀더(11)(11')의 반원경사홈(11A)이 접촉된 디스크(4)는 경사축(6')에 밀려 도7의 원형내에 도시된 바와 같이 보디시트(2)에 점선표시와 같이 밀착된 디스크시트(5)는 보디시트(2)에서 떨어지게 되는데 웜휠(7)의 걸림돌기(7A)가 L2선상에 위치될 때 디스크시트(5)가 최대로 떨어진 상태로 된다.The disc insertion hole 401 of the bearing 4 'and the semi-circular inclined groove 11A of the shaft holders 11 and 11' are in contact with the inclined shaft 6 'of the disc opening / 4 are pushed by the inclined shaft 6 'so that the disc sheet 5 closely attached to the body sheet 2 as shown by the dotted line is dropped from the body sheet 2 as shown in the circular shape of FIG. 7. The worm wheel 7, The disc sheet 5 is at the maximum position when the engaging protrusion 7A of the disc 5 is positioned on the L2 line.

상기의 L2선상에서 L3선상까지 웜휠(7)의 걸림돌기(7A)가 회전되는 동안 디스크개폐축(6)이 회전되어 디스크(4)가 열리게 되는데 이의 작동을 상세히 설명하면 도8의 L2선상에서 L3선상으로 웜휠(7)의 걸림돌기(7A)가 이동시에는 회전판(15)의 긴슬라이더(15A)는 베이스프레이트(14)의 슬라이더 삽입홈(140)의 외측으로 노출되어 있기 때문에 회전되는 걸림돌기(7A)에 밀려 슬라이더삽입홈(140)에서 벗어나게 됨과 동시에 웜휠(7)의 슬라이더끼움홈(701)에 끼워져 안내레일(14A)을 따라 이동하게 되며 긴슬라이더(15A)와 회전판(15)의 회전에 의하여 사각부(6A)가 회전판(15)의 사각구멍(150)에 끼워진 디스크개폐축(6)도 회전하게 된다. 이에 따라 디스크(4)는 열리게 되는 것인데 이때 경사축(6')은 편심캠과 같은 역할을 하기 때문에 디스크(4)는 회전된다.The disk opening and closing shaft 6 is rotated and the disk 4 is opened while the latching protrusion 7A of the worm wheel 7 is rotated from the L2 line to the L3 line in detail. Since the long slider 15A of the rotary plate 15 is exposed to the outside of the slider insertion groove 140 of the base plate 14 when the locking projection 7A of the worm wheel 7 moves on the L3 line, The slider is inserted into the slider insertion groove 140 of the worm wheel 7 and is moved along the guide rail 14A while being rotated by the rotation of the long slider 15A and the rotary plate 15 The disk opening and closing shaft 6, in which the rectangular portion 6A is fitted in the rectangular hole 150 of the rotary plate 15, Accordingly, the disk 4 is opened. At this time, the disk 4 rotates because the inclined shaft 6 'functions like the eccentric cam.

긴슬라이더(15A)가 제어돌기(14B)에 접촉되면 더 이상 회전되지 않음과 동시에 디스크(4)는 최대로 개방된 상태로 되고 걸림돌기(7A)는 도8과 같이 L3선상에 놓여지게 된다. 디스크(4)가 최대로 개방된 상태에서 디스크(4)를 닫고자 할 때는 웜휠(7)을 열 때와는 역으로 작동하면 된다. 즉, 걸림돌기(7A)가 L3선상에 놓여진 상태에서 점선화살표방향으로 회전시키면 웜휠(7)의 슬라이더끼움홈(701)에 긴슬라이더(15A)가 끼워진 회전판(15)도 회전하게 됨과 동시에 디스크개폐축(6)과 디스크(4)도 시계반대방향으로 회전되어 디스크(4)는 닫히게 된다.When the long slider 15A contacts the control protrusion 14B, the disc 4 is not rotated any more and the disc 4 is maximally opened, and the latch protrusion 7A is placed on the L3 line as shown in FIG. When the disk 4 is to be closed in the state where the disk 4 is opened to the maximum, it is required to operate in reverse to the case in which the worm wheel 7 is opened. That is, when the locking protrusion 7A is rotated in the direction of the dotted line in the state of being placed on the L3 line, the rotary plate 15 having the long slider 15A fitted therein is also rotated in the slider fitting groove 701 of the worm wheel 7, The shaft 6 and the disk 4 are also rotated counterclockwise so that the disk 4 is closed.

긴슬라이더(15A)가 슬라이더끼움홈(701)에서 빠져 도9와같이 슬라이더끼움홈(140)에 놓여지게 되면 더 이상 이동되는 것이 정지되고 도8의 L2선상에서 부터는 웜휠(7)과 걸림돌기(7A)및 슬리브(6)의 회전에 의하여 디스크개폐축(6)은 상승되고 디스크(4)의 디스크시트(5)는 수평으로 이동되어 보디시트(2)에 밀착되어 누수를 방지하게 된다.When the long slider 15A is removed from the slider fitting groove 701 and is placed in the slider fitting groove 140 as shown in FIG. 9, the movement of the long slider 15A is stopped and the worm wheel 7 and the engagement protrusion The disc opening and closing shaft 6 is raised and the disc seat 5 of the disc 4 is moved horizontally by being brought into close contact with the body sheet 2 to prevent water leakage.

이와 같은 본 발명은 디스크를 회전시키는 디스크개폐축(6)의 부분에다 경사축(6')을 형성하여 보디시트(2)에 밀착된 디스크(4)의 디스크시트(5)를 보디시트(2)에서 약간 수평으로 이동시켜 떨어지게 한 다음 디스크를 회전시켜 열 수 있도록 하였으므로 보디시트(2)와 디스크시트(5)의 마찰마모를 감소시켜 사용수명을 오래 유지시킬 수 있는 효과가 있다The disk sheet 5 of the disk 4 which is in close contact with the body sheet 2 is formed on the body sheet 2 by forming an inclined shaft 6 ' Since the disc is rotated and opened, it is possible to reduce frictional wear of the body sheet 2 and the disc seat 5, thereby maintaining the service life for a long time
