Description
본 고안은 볼밸브의 밸브몸통(8)을 통과하는 유체의 개·폐에 관한 것으로 유체의 단속을 위하여 볼밸브의 스템(1)을 회전시킴에 따라 결합된 볼(6)이 회전하게 되고 이 때 볼(6)과 볼시트(7)사이에 마찰저항이 발생하게 된다. 또한 이 때 발생된 마찰저항은 볼밸브가 수차례 개·폐 동작을 반복할 경우 상호 마찰저항에 의하여 볼(6)및 볼시트(7)에 손상을 입히게 되어 유체의 단속이 원활하지 못하게 되고 결국에는 누설이 발생하게 된다.The present invention relates to the opening and closing of the fluid passing through the valve body (8) of the ball valve, the combined ball (6) is rotated by rotating the stem (1) of the ball valve for the control of the fluid At this time, friction resistance is generated between the ball 6 and the ball seat 7. In addition, the frictional resistance generated at this time causes damage to the ball 6 and the ball seat 7 due to mutual frictional resistance when the ball valve repeatedly opens and closes several times. Leakage occurs.
또한 관로내에 존재하고 있는 이물질이 볼밸브 내부를 통과할 때 이물질로 인한 볼(6) 및 볼시트(7)의 마모가 발생할 경우 볼밸브의 정확한 단속이 어렵게 되어 볼밸브를 더이상 사용할 수 없게 된다.In addition, when foreign matter existing in the pipeline passes through the inside of the ball valve, wear of the ball 6 and the ball seat 7 due to the foreign matter becomes difficult to precisely control the ball valve, so that the ball valve can no longer be used.
그리고 자동으로 볼밸브를 개·폐 할 경우 볼밸브와 결합된 전동구동기(10)에 필요 이상의 회전력을 요구하게 되는데 이는 전동구동기(10)가 볼밸브를 회전시키기 위하여 필요 이상의 출력으로 구동을 하여야 하므로 전동구동기(10)의 내구성을 저하시키게 된다.And when opening and closing the ball valve automatically requires more than the required rotational force in the electric driver 10 coupled with the ball valve, because the electric driver 10 must be driven to the output more than necessary to rotate the ball valve The durability of the electric driver 10 is reduced.
본 고안은 상기 문제점을 해소하기 위하여 볼밸브의 밸브몸통(8)과 볼시트(7) 사이에 시트오링(9)을 추가하여 볼밸브가 회전시 볼(6)과 볼시트(7) 사이에서 발생하는 마찰저항을 감소시키고 밸브몸통(8) 내부에 이물질 침투로 인한 볼시트(7)의 마모를 방지함으로 볼밸브의 내구성을 증대시키게 된다.The present invention adds a seat O-ring (9) between the valve body (8) and the ball seat (7) of the ball valve in order to solve the above problems between the ball (6) and the ball seat (7) when the ball valve is rotated The durability of the ball valve is increased by reducing frictional resistance generated and preventing wear of the ball seat 7 due to foreign matter infiltration into the valve body 8.
그리고 볼밸브의 안정된 동작으로 전동구동기(10)의 수명을 증대시킴으로써 전동구동기(10)를 이용한 볼밸브의 구동에 보다 원활한 동작을 구현하는데 그 목적이 있다.And the purpose of the more smooth operation to drive the ball valve using the electric drive 10 by increasing the life of the electric drive 10 by the stable operation of the ball valve.
이는 안정된 볼밸브의 회전 동작으로 볼밸브의 및 전동구동기의 내구성을 향상시키고 이물질에 의한 볼(6)과 볼시트(7)의 손상을 최소화시키게 된다.This improves the durability of the ball valve and the electric actuator by the stable rotation of the ball valve and minimizes the damage of the ball 6 and the ball seat 7 due to foreign matter.
또한 시트오링(9)의 추가로 볼밸브의 볼(6)과 볼시트(7)의 마찰저항이 감소되어 최소의 회전력만으로 볼밸브의 구동기 가능하게 되어 전동구동기의 내구성이증가하게 된다.In addition, the frictional resistance between the ball 6 and the ball seat 7 of the ball valve 7 is reduced by the addition of the seat o-ring 9 to enable the ball valve driver with only minimal rotational force, thereby increasing the durability of the electric actuator.

본 고안은 볼밸브를 이용하여 관로내의 유체를 단속하기 위하여 볼밸브의 밸브몸통(8)에 스템오링(4)과 테프론와셔(3)가 조립된 스템(1)을 조립하고, 볼(6)과 스템(1)이 맞물려 볼(6)이 회전을 하게 되고 볼밸브의 기밀유지를 위한 볼시트(7), 볼밸브의 회전력 감소 및 볼밸브 내에 이물질이 침투하여 볼(6)과 볼시트(7)가 손상되는 현상을 방지하기 위하여 추가된 시트오링(9)으로 구성되며, 스템(1)의 회전을 통하여 볼(6)이 회전하게 되는데, 이 때 볼(6)과 볼시트(7)가 관로내 유체를 단속하기 위하여 볼(6)과 볼시트(7) 사이에서 발생하는 마찰저항을 밸브몸통(8)과 볼시트(7) 사이에 배치된 시트오링(9)을 통하여 볼밸브의 회전력이 감소하게 되어 볼밸브의 원활한 동작이 가능하게 되어 과도한 마찰저항을 방지하게 되고 유체가 볼밸브 내부를 통과할 때 관로내의 이물질로 인한 볼시트(7)의 마모를 방지함에 따라 볼밸브의 수명을 증가시키게 된다. 또한 이로 인하여 자동으로 볼밸브를 개·폐 하기 위하여 부착된 전동구동기(10)에 필요이상의 회전력을 요구하지 않게 되어 전동구동기(10)의 수명이 증가하게 된다.The present invention is to assemble the stem (1) assembled with the stem O-ring (4) and Teflon washer (3) in the valve body (8) of the ball valve to control the fluid in the conduit using the ball valve, the ball (6) And stem (1) are engaged, the ball (6) is rotated, the ball seat (7) for maintaining the air tightness of the ball valve, reducing the rotational force of the ball valve and foreign matter penetrates into the ball valve (6) It consists of the seat o-ring (9) added to prevent the damage 7), the ball (6) is rotated through the rotation of the stem (1), the ball (6) and the ball seat (7) The frictional resistance generated between the ball 6 and the ball seat 7 to control the fluid in the conduit is transferred to the ball valve through a seat o-ring 9 disposed between the valve body 8 and the ball seat 7. The rotational force is reduced to enable the smooth operation of the ball valve, which prevents excessive frictional resistance. By preventing wear of the ball seat 7 due to foreign matter, the life of the ball valve is increased. In addition, this does not require more rotational force than the electric driver 10 attached to open and close the ball valve automatically, thereby increasing the life of the electric driver 10.
기존에 사용중인 전동구동기용 볼밸브에 시트오링(9)을 추가함으로써 볼밸브를 이용하여 관로내의 유체를 단속하기 위한 회전력이 최소화 되게 되는데 이는 원활한 볼밸브의 회전을 가능하게 하고 관로내 이물질로 인한 볼(6)과 볼시트(7)의 마모를 방지할 수 있어 볼밸브의 수명이 증가하게 되며, 자동으로 볼밸브를 열고닫기 위한 장치인 전동구동기(10)는 필요이상의 회전력을 요구받지 않게 되어 전동구동기(10)의 수명 또한 증가 되어 관련 비용이 감소하게 된다.By adding a seat o-ring (9) to the existing ball valve for electric actuators, the rotational force for controlling the fluid in the conduit using the ball valve is minimized, which enables smooth rotation of the ball valve and due to foreign substances in the conduit. Since the wear of the ball 6 and the ball seat 7 can be prevented, the life of the ball valve is increased, and the electric actuator 10, which is a device for automatically opening and closing the ball valve, does not require more rotational force than necessary. The lifespan of the electric drive 10 is also increased, thereby reducing the associated costs.
