본 고안은 혼합밸브(Combination Valve)에 관한것으로, 특히, 혼합밸브의 개폐축에 형성된 실린더내에서 슬라이드되는 밸브축의 대향 외주면에 장홈을 형성하여 밸브축이 고압수에 영향을 받지않고 고압이 제거되면서 원활하게 동작될 수 있도록 한 것이다.The present invention relates to a combination valve (Combination Valve), in particular, by forming a long groove on the outer peripheral surface of the valve shaft which slides in the cylinder formed on the opening and closing shaft of the mixing valve as the valve shaft is not affected by the high pressure water and the high pressure is removed It is to be able to operate smoothly.

종래에는 일본 특허공개공보 소49-46224호에 의하여 공지된 혼합밸브가 알려져 있으나, 이는 밸브가 상승될 경우 밸브축이 동축상 별개로 된 개폐축의 단부에서 신축조절될 경우 이 밸브축과 개폐축이 만나는 부분으로 고압수가 미세하게 밀려들어 밸브축의 정상동작시 기민한 작동을 방해하는 배압 공간이 발생되는 문제점이 있었다.Conventionally, a mixing valve known by Japanese Patent Application Laid-open No. 49-46224 is known. However, when the valve is raised, the valve shaft and the opening / closing shaft are adjusted when the valve shaft is stretched and adjusted at the end of the shaft. There was a problem that the back pressure space is generated to interfere with the agile operation in the normal operation of the valve shaft because the high pressure water is finely pushed into the meeting portion.

따라서, 최근에는 국내 실용신안 공고번호 제86-2104호, 국내 실용신안 공개공번 86-621호는 승강봉 하부의 실린더 상부일측에 누수공을 뚫고, 그 내부에 밸브축이 끼워진 구조로서, 승강봉의 상승시 실린더내에 유입된 고압수는 일측에 치우쳐 설치된 누수공을 통해 배출되면서 일측으로 압력이 작용되어 기울어지게 될 뿐만 아니라, 이로 인하여 밸브축은 실린더 내벽과 마찰부하가 걸려 원활하게 동작시키지 못하는 결점이 있었다.Therefore, recently, Korean Utility Model Publication No. 86-2104 and Korean Utility Model Publication No. 86-621 have a structure in which a leakage hole is drilled on one side of an upper part of a cylinder under a lifting rod, and a valve shaft is fitted therein. The high pressure water introduced into the cylinder at the time of rise is discharged through the leakage hole installed on one side, and the pressure is applied to one side, and the valve is inclined. .

본 고안은 이와 같은 종래의 결점을 감안하여 개폐축의 실린더로 삽입되는 밸브축의 대향외주면에 장홈을 형성함으로서 밸브와 밸브축의 기울어짐 없이 밸브가 원활한 개폐동작을 할 수 있도록 한 혼합밸브의 고압수 제거구조를 제공하기 위한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of the above-mentioned drawbacks, forms a long groove on the opposite outer circumferential surface of the valve shaft inserted into the cylinder of the opening / closing shaft so that the valve can be smoothly opened and closed without tilting the valve shaft. To provide a, described in detail by the accompanying drawings as follows.

공급측(2)과 배출측(3)을 밸브시트(11)로 차단한 상태에서 핸들(4)을 돌려 개폐축(5)을 상승시키면 밸브(10)가 상승되면서 공급측(2)과 배출측(3)을 개방하고, 배출측의 수압이 높아지면 스프링(13)과 수압에 의해 밸브(10)가 닫히는 공지의 혼합밸브(1)에 있어서, 개폐축(5)의 실린더(6)에 삽입되는 밸브축(6)의 대향외주면에 장홈(8)(9)을 형성하여 실린더(6)내의 고압수가 장홈(8)(9)을 따라 배출될 수 있도록 구성하여서 된 것이다.In the state where the supply side 2 and the discharge side 3 are blocked by the valve seat 11, the handle 4 is turned to raise the opening / closing shaft 5, and the valve 10 is raised, and the supply side 2 and the discharge side ( 3) In the well-known mixing valve 1 in which the valve 10 is closed by the spring 13 and the water pressure when the water pressure on the discharge side is increased, it is inserted into the cylinder 6 of the opening / closing shaft 5. Long grooves 8 and 9 are formed on opposite outer circumferential surfaces of the valve shaft 6 so that the high pressure water in the cylinder 6 can be discharged along the long grooves 8 and 9.

이와 같이 구성된 본 고안은 공급측(2)의 공급수를 배출측(3)으로 보내기 위해 핸들(4)을 돌려 개폐축(5)이 핸들(4)방향으로 상승되도록 하면 공급측(2)에 있는 공급수의 압력에 의해 밸브(10)가 스프링(13)을 압축하면서 개폐축(5)을 따라 상향 이동하여 공급측(2)과 배출측(3)을 개방시킨다.The present invention configured as described above supplies the feed on the supply side 2 by turning the handle 4 so that the opening and closing shaft 5 rises in the direction of the handle 4 to send the feed water from the supply side 2 to the discharge side 3. By the pressure of the water, the valve 10 moves upward along the opening / closing shaft 5 while compressing the spring 13 to open the supply side 2 and the discharge side 3.

한편, 공급측(2)의 공급수가 배출측(3)으로 흐르면서 배출측(3)의 수압이 공급측(2)보다 높아지면 수압과 스프링(13)의 힘에 의해 밸브(10)가 하향이동하여 닫히면서 공급측(2)과 배출측(3)을 차단한다.On the other hand, when the supply pressure of the supply side (2) flows to the discharge side (3) and the water pressure of the discharge side (3) is higher than the supply side (2) when the valve 10 is moved downward by the pressure of the hydraulic pressure and the spring 13 is closed The supply side (2) and the discharge side (3).

이때, 밸브(10)가 열려있던 상태에서 배출측(3)의 고압수가 개폐측(5)의 실린더(6)내로 유입된 고압수는 일측장홈에서 타측장홈을 통해 유출되면서 수압이 떨어져 밸브(10)가 닫힐때 밸브측(7)이 실린더(6) 내에서 원활하게 슬라이드 될 뿐만 아니라, 공급측(2)의 수압이 배출측(3)보다 높아져서 밸브(10)가 다시 열릴때도 밸브측(7)은 실린더(6)내의 고압수를 배출하면서 원활하게 실린더(6)내로 삽입된다.At this time, the high pressure water introduced into the cylinder 6 of the opening and closing side 5 in the state in which the valve 10 is open flows out from the one long side groove through the other long side groove, so that the water pressure drops and the valve 10 Valve side 7 smoothly slides in the cylinder 6 when the valve is closed, and the valve side 7 is opened even when the valve 10 is opened again because the hydraulic pressure of the supply side 2 becomes higher than the discharge side 3. Is smoothly inserted into the cylinder 6 while discharging the high pressure water in the cylinder 6.

또한, 밸브축(7)에는 원주면의 대향측에 장홈(8)(9)이 형성되어 밸브(10)가 개폐될때 밸브축(7)이 수압을 균일하게 받게 되므로 밸브(10)의 개폐동작시 기울어짐이 방지되고 개폐동작이 유연하게 이루어지는 것이다.In addition, the valve shaft 7 has long grooves 8 and 9 formed on the opposite side of the circumferential surface thereof, so that the valve shaft 7 receives water pressure uniformly when the valve 10 opens and closes, thereby opening and closing the valve 10. When tilting is prevented and the opening and closing operation is made smoothly.

한편, 제4도의 다른 실시예와 같이 개폐축(5)의 실린더(6) 내면에 장홈(8')(9')을 대향되게 형성하여도 본 고안의 목적인 밸브(10)의 원활한 개폐동작은 밸브축(7)에 장홈(8)(9)을 형성한 때와 같이 이룰 수 있는 것이다.On the other hand, the smooth opening and closing operation of the valve 10, which is the object of the present invention, even if the long grooves 8 'and 9' are formed on the inner surface of the cylinder 6 of the opening and closing shaft 5 as in the other embodiment of FIG. This can be achieved as when the long grooves 8 and 9 are formed in the valve shaft 7.

상기에서와 같이 본 고안은 혼합밸브의 개폐축에 형성된 실린더에 삽입되는 밸브축의 대향외주면에 장홈을 형성함으로서 실린더내로 유입된 고압수를 원활이 배출하고 밸브축을 원활하게 슬라이드시킬 수 있을 뿐만 아니라, 이로 인하여 공급측과 배출측을 개폐시키는 밸브도 원활하게 동작시킬 수 있는 효과가 있다.As described above, the present invention forms a long groove on the opposite outer circumferential surface of the valve shaft inserted into the cylinder formed on the open / close shaft of the mixing valve, thereby smoothly discharging the high pressure water introduced into the cylinder and smoothly sliding the valve shaft. Due to this, there is an effect that the valve for opening and closing the supply side and the discharge side can be operated smoothly.
