본 발명은 수밀성과 조작성이 향상된 볼 타입 제수변에 관한 것으로, 볼을 회전시키는 회전축에 패킹을 설치하여 수밀성을 향상시키고, 바디에 설치된 시트링에 링스프링을 설치하여 볼의 회전 작동시에 부하를 줄임과 동시에 시트링의 마모가 진행되더라도 링스프링에 의해 수밀성이 유지되도록 구성된 볼 타입 제수변에 관한 것이다.The present invention relates to a ball type dividing valve with improved watertightness and operability, and improves watertightness by installing a packing on a rotating shaft for rotating the ball, and installs a ring spring on the seat ring installed on the body to reduce load during rotation of the ball. And at the same time it relates to a ball-type distillation valve configured to maintain watertightness by the ring spring even if the wear of the seat ring progresses.

볼 타입 제수변은 유체를 단속하거나 흐름량을 조절하는 장치로서, 바디의 내부에 통공이 관통된 볼이 설치된 구조이다. 볼은 회전축이 고정되어 회전축의 조작으로 통공의 방향을 조절함으로써 유체를 제어하는 구조로서, 사출 방법으로 제조된다.The ball type dividing valve is a device for controlling the flow or regulating the flow rate, and has a structure in which a ball having a through hole is installed inside the body. The ball has a structure in which the rotating shaft is fixed and the fluid is controlled by adjusting the direction of the through hole by manipulation of the rotating shaft, and is manufactured by an injection method.

그리고 바디의 상부에는 회전축이 삽입되는 축관부가 형성되고, 축관부 상부에는 체결을 위한 캡이 볼트와 패킹에 의해 축관부에 고정되는 구조이다.And the upper part of the body is formed with a shaft tube portion is inserted into the rotating shaft, the cap for fastening the shaft tube portion is a structure that is fixed to the shaft tube portion by the bolt and packing.

수밀을 위한 구조는 회전축과 축관부의 사이에 오링이 설치되는데 오링은 축 관부 또는 회전축에 형성된 홈에 끼워진 구조이다. 그리고 볼과 바디의 사이에 시트링이 설치되는데, 시트링은 바디의 홈에 끼워진다. 그리고 시트링의 볼의 면과 접촉되는 부분에는 수밀성 향상을 위하여 다수 개의 돌조가 형성된 구조이다.In the structure for watertight, an O-ring is installed between the rotating shaft and the shaft tube portion. The O-ring is a structure inserted into a groove formed in the shaft tube portion or the rotating shaft. And a seat ring is installed between the ball and the body, the seat ring is fitted into the groove of the body. In addition, the part contacting the surface of the ball of the seat ring has a structure in which a plurality of protrusions are formed to improve watertightness.

상기와 같은 종래의 볼 타입 제수변의 구조는 우선 회전축과 축관부의 수밀에는 오링이 사용된다. 그러나 오링이 손상이 발생될 경우 2차적인 수밀의 구조가 없어 회전축의 외측면을 따라 유체가 누출되는 문제가 있다.In the structure of the conventional ball type dividing valve as described above, first, an O-ring is used for watertight rotation of the rotating shaft and the shaft tube portion. However, when the O-ring is damaged, there is no secondary watertight structure and there is a problem in that fluid leaks along the outer surface of the rotating shaft.

그리고 볼에 접촉되어 수밀을 유지시키는 시트링 또한 마모가 진행되면 누수가 일어나고, 이를 방지하기 위하여 큰 힘으로 수밀되게 설치할 경우 볼의 조작이 힘들어지는 문제가 있었다.In addition, the seat ring is in contact with the ball to maintain the watertight leak also occurs when the wear progresses, there was a problem that the operation of the ball is difficult to install when watertightly installed with a large force to prevent this.

따라서 본 발명은 상기와 같은 종래의 문제점을 해소하고자 하는 것으로, 볼 타입 제수변의 수밀성을 향상시키면서 동시에 볼의 조작이 용이하게 이루어지도록 하는 구조를 제공함에 목적이 있다.Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide a structure for easily manipulating the ball while improving the watertightness of the ball type dividing valve.

상기의 목적을 달성하기 위하여 본 발명은 회전축에 이중의 수밀 구조를 형성시키기 위하여 회전축에 축돌조를 형성시키고, 상기 축돌조의 상단부와 캡의 하단부 사이에 패킹을 삽입하여 회전축에 설치된 오링의 손상에 대비하도록 한다. 그 리고 시트링의 바깥쪽에 홈을 형성하고 상기 홈에 링스프링을 삽입하여 바디에 지지되게 함으로써, 시트링의 돌조가 마모되더라도 시트링이 볼에 밀찰되도록 하는 힘을 부여하는 구조를 제공하게 된다.In order to achieve the above object, the present invention forms a shaft protrusion on the rotating shaft to form a double watertight structure on the rotating shaft, and inserts a packing between the upper end of the shaft and the lower end of the cap to prepare for damage to the O-ring installed on the rotating shaft. Do it. In addition, by forming a groove on the outside of the seat ring and inserting a ring spring in the groove to be supported by the body, it provides a structure that gives the seat ring to the ball even if the protrusion of the seat ring wears.

본 발명에 따르면, 회전축에 이중의 수밀 구조를 가짐으로써 회전축을 따라 쉽게 누수가 되던 종래의 문제점을 해소하게 된다. 그리고 볼에 접촉되는 시트링이 마모가 되더라도 초기 수밀 상태를 그대로 유지할 수 있을 뿐만 아니라 볼의 조작이 유연하기 이루어지는 효과가 있다.According to the present invention, having a double watertight structure on the rotating shaft solves the conventional problem of easily leaking along the rotating shaft. And even if the seat ring in contact with the ball wears can not only maintain the initial watertight state, but also has the effect that the operation of the ball is flexible.

본 발명에 의한 볼 타입 제수변은 수밀성을 향상시키는 구조적 특징을 가지는 것으로, 우선 회전축(1)에 이중의 수밀 구조를 가진다. 그리고 볼(2)에 접촉되는 시트링(3)이 마모가 진행되더라도 항상 일정한 힘으로 볼(2)의 표면에 접촉되도록 하는 구조적 특징을 가진다.The ball type dividing valve according to the present invention has a structural feature for improving watertightness, and firstly, has a double watertight structure on the rotating shaft 1. And the seat ring (3) in contact with the ball (2) has a structural feature such that even if the wear proceeds to always contact the surface of the ball (2) with a constant force.

따라서 내부에 형성된 홈에 시트링(3)이 설치된 바디(4); 바디(4)의 상부에 설치된 축관부(5); 바디(4)의 내부에 설치되어 시트링(3)에 접촉되어 회전되는 볼(2); 볼(2)에 고정되고 축관부(5)를 통해 상부로 돌출된 회전축(1); 축관부(5)의 상부에 체결되어 회전축(1)을 지지하는 캡(6);을 포함하여 구성된 볼 타입 제수변에 있어서, 상기 축관부(5)에 위치된 회전축(1)에 축돌조(7)가 빙둘러 형성되고, 상기 축돌조(7)와 캡(6)의 하부에 패킹(8)이 설치되어 수밀을 유지시키는 구조이다.Therefore, the body 4 is provided with a seat ring 3 in the groove formed therein; A shaft tube portion 5 installed on the upper portion of the body 4; A ball 2 installed inside the body 4 and rotating in contact with the seat ring 3; A rotating shaft 1 fixed to the ball 2 and protruding upward through the shaft pipe portion 5; In the ball-type dilution valve comprising a cap (6) fastened to the upper portion of the shaft tube portion 5 to support the rotating shaft (1), the shaft projection (7) on the rotating shaft (1) located in the shaft tube portion (5) ) Is formed round and the packing (8) is installed in the lower portion of the axial projection 7 and the cap (6) to maintain the watertight.

그리고 상기 시트링(3)의 바디(4)측 접촉면에 홈이 형성되고, 상기 홈에 링스프링(9)이 설치되어, 시트링(3)이 볼(2) 접촉면으로 밀착된 구조이다.In addition, a groove is formed in the body 4 side contact surface of the seat ring 3, a ring spring 9 is installed in the groove, and the seat ring 3 is in close contact with the ball 2 contact surface.

볼 타입 제수변은 회전축(1)에 고정된 볼(2)의 회전에 의하여 볼(2)에 형성된 통로의 개구 면적의 변화에 의해 유량의 제어와 단속이 이루어진다.The ball type dividing valve controls and regulates the flow rate by the change of the opening area of the passage formed in the ball 2 by the rotation of the ball 2 fixed to the rotating shaft 1.

높은 수압은 특히 회전축(1)을 따라 상부로 누출되는데, 이를 방지하기 위하여 종래에는 도 2에 도시된 바와 같이 회전축(1)에 빙둘러 오링(10)이 설치되었다. 그러나 종래의 경우 하나의 오링(10)만으로 수밀을 이룰 수가 없어, 사용중에 회전축(1)을 따라 누수가 일어나는 문제가 있었다.The high water pressure leaks upward along the rotary shaft 1, in particular, in order to prevent this, the O-ring 10 has been conventionally installed around the rotary shaft 1 as shown in FIG. However, in the conventional case, the watertightness cannot be achieved with only one O-ring 10, and there is a problem that water leaks along the rotating shaft 1 during use.

따라서 본 발명은 오링(10)이 손상되어 누수가 일어나더라도 수밀을 이룰 수 있도록, 종래의 오링(10) 위치보다 외측에 패킹(8)이 설치된 구조이다. 따라서 오링(10)이 기능을 하고 있을 때에는 패킹(8)으로 가해지는 수압이 없기 때문에 별다른 작용을 하지 않으나, 오링(10)을 통해 수압이 패킹(8)에 가해질 경우에는 수압이 패킹(8)을 상부의 캡(6)으로 밀게 되므로, 수밀을 유지할 수 있게 된다.Therefore, the present invention has a structure in which the packing 8 is installed on the outer side of the conventional O-ring 10 position so that the O-ring 10 may be watertight even if the leak occurs. Therefore, when the O-ring 10 is functioning, since there is no water pressure applied to the packing 8, there is no special effect. However, when the water pressure is applied to the packing 8 through the O-ring 10, the water pressure is packed (8). Since it is pushed to the upper cap (6), it is possible to maintain the watertight.

이와 같이 오링(10)이 제 기능을 하는 평소에는 제수변 조작에 별다를 저항으로 작용하지 않고 있다가 오링(10)의 손상시 누수에 의해 수밀을 행하도록 하는 구조적 특징을 가지게 된다.As described above, the O-ring 10 does not function as a resistance to the operation of the dilution valve, but has a structural feature to perform watertightness due to leakage when the O-ring 10 is damaged.

그리고 본 발명은 볼(2)에 접촉되어 수밀을 행하는 시트링(3)의 구조적 특징으로 조작의 수월함과 수밀성의 향상을 가져오게 된다.In addition, the present invention brings the improvement of the ease of operation and the watertightness by the structural feature of the seat ring 3 which contacts the ball 2 and performs watertightness.

본 발명의 시트링(3)은 도 3에 도시된 바와 같이 홈이 형성되고, 상기 홈에 링스프링(9)이 설치된 구조이다. 따라서 링스프링(9)의 탄성복원력에 의해 시트링(3)이 항상 일정한 힘으로 볼(2)에 접촉된 상태를 유지하게 된다.The seat ring 3 of the present invention has a structure in which a groove is formed as shown in FIG. 3, and a ring spring 9 is installed in the groove. Therefore, by the elastic restoring force of the ring spring 9, the seat ring 3 is always kept in contact with the ball 2 with a constant force.

종래의 경우 시트링(3)의 볼(2) 접촉면에 형성된 돌조(11)들이 사용에 의해 마모가 될 경우 수밀성이 저하되었다. 그러나 본 발명은 마모가 일어나더라도 링스프링(9)에 의해 항상 일정한 힘으로 시트링(3)이 볼(2)에 접촉되므로 수밀성이 그대로 유지되는 특성을 가진다.In the conventional case, when the protrusions 11 formed on the contact surface of the ball 2 of the seat ring 3 become worn by use, the watertightness is deteriorated. However, the present invention has the characteristic that the watertightness is maintained as the seat ring 3 is in contact with the ball 2 with a constant force at all times by the ring spring 9 even if wear occurs.
