본 고안은 방향 전환 밸브의 개폐장치에 관한 것으로서, 보다 상세하게는 2방향 또는 그 이상의 방향 전환제어시 볼 밸브의 회전 원호운동에 의해 출구포트를 서서히 차단함과 아울러 출구포트와 접촉이 매번 다르게 이루어지도록 하여 볼밸브의 파손을 방지하고, 구조적으로 간단하게 하여 원가절감을 추구할 수 있도록 한 방향전환 밸브의 개폐장치에 관한 것이다.The present invention relates to an opening and closing device of the directional valve, more specifically, the outlet port is gradually blocked and the contact with the outlet port is made differently every time by the circular arc motion of the ball valve during two-way or more direction control. The present invention relates to an opening and closing device of a directional valve to prevent breakage of a ball valve and to pursue cost reduction by structurally simple.

제4도는 종래 기술의 방향 전환 밸브의 개폐장치의 측단면도이고, 제5도는 요부 평면도로서, 도시되지 않은 제어부의 출력 신호에 따라 작동되는 모우터(50) 축에 구동기어(52)가 마련되어, 이 구동기어(52)와 감속기어군(54)을 개재하여 모우터(50)의 회전력을 감속한 다음 종동기어(56)로 전달되며, 이들 기어군은 하우징(58)에 수납된 상태로 보전되어 있다.4 is a side cross-sectional view of the opening and closing device of the direction change valve of the prior art, and FIG. 5 is a plan view of the main portion, in which a drive gear 52 is provided on a motor 50 shaft operated according to an output signal of a controller (not shown). Via the drive gear 52 and the reduction gear group 54, the rotational force of the motor 50 is decelerated and then transmitted to the driven gear 56, and these gear groups are stored in the housing 58 and are kept. have.

상기한 하우징(58)의 상측에는 유도를 선택적으로 개폐하고, 고무재질로 형성된 볼 밸브(60)를 지지하는 하부 플레이트(62)가 고정 설치되고, 상기 하부 플레이트(62)의 일측에는 상기한 종동기어(56)가 돌출되어 동일한 토오크가 발생되는 복수의 탄성부재(64)(66)로 탄발 설치된 회전판(68)에 모우터(50)의 회전력이 전달되도록 되어 있다.A lower plate 62 is fixedly installed on the upper side of the housing 58 to selectively open and close the induction, and supports the ball valve 60 formed of a rubber material. The driven plate is provided on one side of the lower plate 62. The rotational force of the motor 50 is transmitted to the rotating plate 68 which is provided with a plurality of elastic members 64 and 66 which protrude the gear 56 to generate the same torque.

그리고, 상기한 볼 밸브(60)는 하부 플레이트(62)에 고정 설치되는 상부 플레이트(70)의 가이드(72)에 축지지됨과 아울러 상기 종동기이(56)와 치합되는 기어부(68a)를 보유한 회전판(68)과 함께 회전되는 한지축(74)의 상단에 직교방향으로 설치된 링크(76)에 편심 고정 설치됨으로써, 상기 모우터(50)의 회전력이 회전판(68)에 전달됨에 따라 함께 회전되는 힌지축(74)에 의해 소정의 원호상의 변위를 갖도록되어 입, 출구를 선택적으로 개폐하도록 되어 있다.The ball valve 60 is axially supported by the guide 72 of the upper plate 70 fixed to the lower plate 62 and has a gear portion 68a engaged with the follower 56. By being eccentrically fixed to the link 76 installed in the orthogonal direction at the upper end of the Hanji shaft 74 rotates with the rotating plate 68, the rotational force of the motor 50 is rotated together as it is transmitted to the rotating plate 68 The hinge shaft 74 has a predetermined arc-shaped displacement to selectively open and close the inlet and the outlet.

제6도는 종래 기술의 개폐장치가 공급튜브(78)에 장착된 상태를 나타내는 도면으로, 상기 공급튜브(78)는 유체나 공기가 공급되는 입구포트(80)가 형성됨과 아울러 그와 동일 수평 상태의 직교하는 위치에 제1, 2 출구포트(82, 84)가 형성되어 볼 밸브(60)의 선택적인 작동에 의해 입, 출구포트(78)(82, 84)가 차단되어 유로의 흐름을 절환하도록 되어 있다.6 is a view showing a state in which the opening and closing device of the prior art is mounted on the supply tube 78, the supply tube 78 is formed with the inlet port 80 is supplied with the fluid or air and the same horizontal state The first and second outlet ports 82 and 84 are formed at positions orthogonal to each other so that the inlet and outlet ports 78 and 82 and 84 are blocked by the selective operation of the ball valve 60 to switch the flow of the flow path. It is supposed to be.

이와 같이 구성되는 종래 기술의 방향 전환 밸브의 개폐장치는, 제어부의 출력 신호에 의해 모우터(50)를 정방향으로 작동시키면, 그 회전력이 구동기어(52)와, 감속 기어군(54)에 의해 규정된 속도로 감속되어 하부 플레이트(62)에 돌출된 종동기이(56)를 통해 회전판(68)에 전달된다.In the opening and closing apparatus of the conventional direction switching valve configured as described above, when the motor 50 is operated in the forward direction by the output signal of the controller, the rotational force is driven by the drive gear 52 and the reduction gear group 54. The follower 56, which is decelerated at a defined speed and protrudes from the lower plate 62, is transmitted to the rotating plate 68.

따라서 회전판(68)은 각각의 탄성부재(64)(66)의 탄성력을 극복하고 힌지축(74)을 중심으로 시계방향으로 소정의 각도로 회전됨으로써, 상기 힌지축(74)의 상단에 고정 설치된 링크(76)의 원호상의 변위에 따라 그 선단에 제공된 볼 밸브(60)는 제7도 (a)에 도시한 바와 같은 상태에서 (b)에 도시한 바와 같이 제2 출구포트(84)를 차단하게 되어 공급튜브(78)의 입구포트(80)로부터 공급된 유체는 제1출구포트(82)를 통해 송출되게 된다.Therefore, the rotating plate 68 is fixed to the upper end of the hinge shaft 74 by overcoming the elastic force of each elastic member 64, 66 and rotated at a predetermined angle clockwise around the hinge axis 74 According to the arc-shaped displacement of the link 76, the ball valve 60 provided at its tip blocks the second outlet port 84 as shown in (b) in a state as shown in Fig. 7 (a). The fluid supplied from the inlet port 80 of the supply tube 78 is sent out through the first outlet port 82.

이때 제어부의 출력 신호가 차단되어 모우터(50)가 정지되게 되면, 회전판(68)은 탄성부재(64)(66)의 복원력에 의해 전기한 작동과 반대로 작동되게 된다.At this time, when the output signal of the control unit is blocked and the motor 50 is stopped, the rotating plate 68 is operated in the opposite direction to the electric operation by the restoring force of the elastic members 64 and 66.

따라서 회전판(68)의 기어부(68a)에 치차 결합된 종동기어(56), 감속 기어군(54)을 통해 모우터(50)는 역회전됨과 아울러 회전판(68)과 함께 회전되는 힌지축(74)에 의해 볼 밸브(60)가 반대로 회전됨으로써, 상기 볼 밸브(60)에 의해 차단되었던 제2출구포트(84)가 개방되고 제1출구포트(82)는 차단되어 공급튜브(78)의 입구포트(80)로 부터 공급된 유체의 흐름을 전환하게 된다.Accordingly, the motor 50 is reversely rotated through the driven gear 56 and the reduction gear group 54 geared to the gear portion 68a of the rotating plate 68 and the hinge shaft rotated together with the rotating plate 68. 74, the ball valve 60 is rotated in the opposite direction, so that the second outlet port 84, which has been blocked by the ball valve 60, is opened and the first outlet port 82 is blocked so that the supply tube 78 The flow of fluid supplied from the inlet port 80 is switched.

이와 같은 종래 기술의 방향 전환 밸브의 개폐장치는, 제어부의 출력신호에 따라 제어되는 모우터(50)의 작동에 의해 그 회전력이 회전판(68)에 전달되어, 이와 함께 회전되는 힌지축(74)과 편심 고정 설치된 볼 밸브(60)가 소정의 각도로 회전 왕복 운동함으로써, 공급튜브(78)에 형성된 각각의 출구포트(82, 84)을 선택적으로 차단할 수 있지만, 모우터(50)에 의해 회전된 볼 밸브(60)의 회전 왕복운동을 전환시키기 위해 한쌍의 탄성부재(64)(66) 등의 전환장치가 마련되어야 하기 때문에 구조적으로 복잡하고, 또한 볼 밸브(60)의 회전 이동시 볼 밸브(60)는 자전하지 않고 출구포트(82, 84)의 전면적을 순간적으로 차단시키기 때문에 수압의 급격한 변화에 의해 수격현상이 초래되게 된다.The opening and closing device of the direction change valve of the prior art, the rotational force is transmitted to the rotating plate 68 by the operation of the motor 50 controlled in accordance with the output signal of the control unit, the hinge shaft 74 is rotated with it. And the eccentrically fixed ball valve 60 rotates reciprocally at a predetermined angle, it is possible to selectively block the respective outlet ports 82, 84 formed in the supply tube 78, but rotates by the motor 50 In order to switch the rotary reciprocating motion of the ball valve 60, a pair of resilient members 64, 66 and the like must be provided, so that it is structurally complicated, and the ball valve 60 60 does not rotate, but immediately shuts off the entire area of the outlet ports 82 and 84, causing water hammer due to a sudden change in water pressure.

게다가, 링크(76)에 볼 밸브(60)가 고정 설치되어 있고, 상기 볼 밸브(60)는 회전 왕복운동 거리가 항상 제한되어 있기 때문에 각각의 출구포트(82, 84)와 접촉되는 부위가 항상 동일하여 고무재질의 볼 밸브(60)의 파손이 발생되어 유로의 차단이 정확하게 이루어지지 않은 제반 문제점이 내재되어 있다.In addition, since the ball valve 60 is fixedly installed at the link 76 and the ball valve 60 is always limited in rotational reciprocating distance, the part contacting each outlet port 82 and 84 is always present. In the same way, there is an inherent problem that breakage of the ball valve 60 made of rubber material occurs, so that the flow path is not blocked accurately.

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위해 안출된 것으로서, 본 고안의 목적은 2방향 또는 그 이상의 방향 전환 제어시 볼 밸브의 회전 원호운동에 의해 출구포트를 서서히 차단함과 아울러 출구포트와 접촉이 매번 다르게 이루어지도록 하여 볼 밸브의 파손을 방지함은 물론 수압의 급격한 변화에 발생되는 수격현상의 초래를 방지하고, 볼 밸브의 회전방향을 일방향으로 하여 구조적으로 간단하게 함으로써, 원가절감을 추구할 수 있는 방향 전환 밸브의 개폐장치를 제공하는데 있다.The present invention is devised to solve the problems of the prior art as described above, the object of the present invention is to gradually block the outlet port by the rotation arc motion of the ball valve in the control of the switching direction of two or more directions By making contact with the port differently every time, it prevents damage to the ball valve and prevents water hammer caused by sudden changes in water pressure, and reduces the cost by simplifying the structure of the ball valve in one direction. To provide an opening and closing device of the directional valve that can pursue.

As described above, when the second outlet port 29 of the supply tube 23 is blocked and the operation of the motor 1 is stopped by the operation of the control means, the fluid supplied to the supply tube 23 is discharged to the first outlet. The ball valve 21 is blocked by the inlet port 25 as shown in (d) of FIG. Accordingly, the fluid flow to both outlet ports 27 and 29 is simultaneously blocked.

이와 같이 조작 스위치의 조작에 따라 모우터(1)가 작동되어 편심 크랭크 밸브 축(15)에 제공된 볼 밸브(21)가 각각의 입, 출구 포트(25)(27)(29)를 차단할때, 상기 볼 벨브(2l)는 편심 크랭크 밸브 축(15)과 회전가능하게 설치됨에 따라 편심 크랭크 밸브 축(15)과 함께 회전 운동할 때, 입, 출구 포트(25)(27)(29)의 단부와 상호 접촉에 의해 자전되기 때문에 입, 출구 포트(25)(27)(29)를 차단할 때마다 위치 변화가 일어나게 되어 볼 밸브(2l)의 파손을 방지하게 되며, 전면적으로 급작스런 차단을 방지하여 압력 변동에 의해 수격현상 발생을 방지하게 된다.When the motor 1 is operated in accordance with the operation of the operation switch as described above, when the ball valve 21 provided on the eccentric crank valve shaft 15 blocks the respective inlet and outlet ports 25, 27, 29, The ball valve 2l is rotatably installed with the eccentric crank valve shaft 15, so that the ball valve 2l is rotated together with the eccentric crank valve shaft 15, and ends of the inlet and outlet ports 25, 27, 29 are provided. Since it rotates by mutual contact with each other, the position change occurs whenever the inlet and outlet ports 25, 27 and 29 are blocked, thereby preventing breakage of the ball valve 2l, and preventing sudden shutoff across the entire surface. The change prevents the occurrence of water hammer.

이와 같은 본 고안의 개폐장지는, 난방수와 온수의 분배를 방이나 거실 등의 난방 장소에 마련된 조작 스위치를 통해 밸브를 제어할 수 있기 때문에 보일러의 온수 분배장치에 적용하면 매우 효과적이다.The opening and closing of the present invention is very effective when applied to the hot water distribution device of the boiler because it can control the valve through the operation switch provided in the heating place, such as room or living room, the distribution of heating water and hot water.

이상 설명한 바와 같이 본 고안의 방향 전환 밸브의 개폐장치는, 조작 스위치의 조작에 따라 일방향으로 작동되는 모우터에 의해 편심 크랭크 밸브 축이 소정의 반경으로 회전 운동함으로써, 그 선단에 제공된 볼 밸브가 각각의 입, 출구 포트를 선택적으로 차단하기 때문에 유체의 흐름 방향을 제어함과 아울러 볼 밸브가 각각의 입, 출구포트를 차단할때, 편심 크랭크 밸브 축과 회전 가능하게 설치되어 입, 출구포트의 선단부와 접촉되어 자전되기 때문에 전면적인 차단시 급작스런 유압 변동이 발생하지 않아 수격현상 발생을 방지할 수 있으며, 입, 출구포트의 차단시 마다 볼 밸브의 접촉부위가 다르게 접촉되기 때문에 동일 위치의 찍힘에 의한 파손을 미연에 방지하여 내구성을 향상시킴으로써, 공급튜브로부터 송출되는 유체의 흐름을 정확하게 제어할 수 있는 이점이 있다.As described above, the opening and closing device of the direction switching valve of the present invention, the eccentric crank valve shaft is rotated by a predetermined radius by a motor operated in one direction in accordance with the operation of the operation switch, so that the ball valve provided at the tip of each By selectively blocking the inlet and outlet ports of the valve, it controls the flow direction of the fluid, and when the ball valve blocks the respective inlet and outlet ports, it is rotatably installed with the eccentric crank valve shaft and the tip of the inlet and outlet ports. Since it is contacted and rotated, there is no sudden hydraulic fluctuation when it is shut off completely to prevent water hammer.Because the contact part of the ball valve is contacted differently when the inlet and outlet ports are blocked, damage caused by the same position is damaged. By improving the durability and preventing the flow of fluid from the supply tube There is an advantage that can control.

한편, 볼 밸브가 일방향으로 회전 운동하도록 함으로써, 종래의 회전 왕복운동을 제어하는 변환장치가 필요없기 때문에 구조적으로 간단하여 부품수를 줄일 수 있어 제조원가를 절감할 수 있는 이점도 있다.On the other hand, by allowing the ball valve to rotate in one direction, since there is no need for a conventional converter for controlling the rotational reciprocating motion is structurally simple to reduce the number of parts there is an advantage that can reduce the manufacturing cost.
