Abstract

본 발명은 상.하수도의 펌프장 또는 수충격 및 서지(SURGE)현상, 캐비테이션(CABITATION)현상등이 많이 발생하는 관로에 연결하여 사용되는 고압 콘트롤 밸브(CONTROL VALVE)에 관한 것으로서,The present invention relates to a high pressure control valve (CONTROL VALVE) used in connection to a pump station of water and sewage, or a pipeline in which water shock, surge, cavitation, and the like occur a lot.

본 발명의 특징은 펌프장 및 관로내의 유량이 급격히 변하지 않고, 유체의 흐름이 매우 양호함으로 인해 수충격, 서지현상, 캐비테이션 현상등이 현저하게 없어지게 한데 있다.A characteristic of the present invention is that the flow rate in the pump station and the pipe line does not change rapidly, and because of the very good flow of fluid, water shock, surge phenomenon, cavitation phenomenon, etc. are remarkably eliminated.

Description

고압 콘트롤 밸브{HIGH PRESSURE CONTROL VALVE}HIGH PRESSURE CONTROL VALVE

본 발명은 고압 콘트롤 밸브에 관한 것으로서 종래에는 펌프에서 뿜어 나오는 고압의 유체를 자동으로 조절하지 못하는 접형변, 글로우밸브, 제수변등을 연결함으로 인해 수충격, 서지(SURGE)현상, 캐비테이션 현상, 진공현상등이 발생하여 관로에 연결되어 있는 기자재등을 자주 파손시켰으며,The present invention relates to a high pressure control valve, and in the related art, a water shock, a surge phenomenon, a cavitation phenomenon, a vacuum phenomenon by connecting a spherical valve, a glow valve, a dilution valve, etc., which are not automatically controlled by a high pressure fluid discharged from a pump. Caused frequent damage to equipment connected to the pipeline,

또한, 펌프에서 뿜어낸 유체가 정전으로 인하여 강한 유체가 되돌아와 수충격을 가할시 밸브의 디스크 파손 및 기자재등이 심하게 파손되는 경향이 빈번하였다.In addition, when the fluid discharged from the pump is strong due to the power failure, the fluid tends to damage the disk and equipment of the valve severely when the water shock is applied.

본 발명은 상기와 같은 문제점을 해결하기 위하여The present invention to solve the above problems

밸브내의 유체가 스므스(SMOOTH)하게 흐르게 하기 위하여 몸체(31)를 유선형으로 형성하고, 고압의 유체가 발생시 다이아후램(11)(12)을 유체내의 압력으로 인하여 자동으로 상.하 조정하여 유체의 흐름이 파동이 없게 한 것으로서,In order to make the fluid in the valve flow smoothly, the body 31 is streamlined, and when a high pressure fluid is generated, the diaphragm 11 and 12 are automatically adjusted up and down due to the pressure in the fluid. As the flow did not have a wave,

밸브몸체(31) 내부의 돌출된 부분에 몸체시트(19)를 고착하고,The body seat 19 is fixed to the protruding part inside the valve body 31,

상부의 접촉면에는 씰디스크(35)를 형성하여 하단부에는 씰디스크시트(24)를 삽입하고 하부면에는 씰디스크와샤(25)를 덮고, 와샤스크류(26)로 죄임하고 씰디스크(35)의 상단에는 스프링(33)을 올려 놓는다.A seal disk 35 is formed on the upper contact surface, and a seal disk sheet 24 is inserted into the lower end, and a seal disk washer 25 is covered on the lower surface. Put the spring 33 on.

또한, 씰디스크(35) 중심에는 축(21)을 형성하고 축(21)의In addition, the shaft 21 is formed at the center of the seal disc 35 and the shaft 21

상단부에는 한쌍의 다이아후램(11)(12)를 삽입하고 샤프트너트(9)로서 죄임한 후 로크너트(8)로서 고정시킨다.A pair of diaphragms 11 and 12 is inserted into the upper end and tightened as a shaft nut 9 and then fixed as a lock nut 8.

그리그 밸브몸체(31) 상단에는 카바(4)를 형성하여, 하단에는 축(21)이 좌우로 움직이지 않게 베어링(16)을 끼우고 베어링(16)의 내면에는 축오링(17)을 삽입하며, 외부에는 배어링오링(18)을 삽입한다.A cover 4 is formed at the top of the grease valve body 31, and the bearing 16 is inserted at the lower end so that the shaft 21 does not move left and right, and the shaft o-ring 17 is inserted into the inner surface of the bearing 16. Insert the bearing O-ring 18 to the outside.

위와같이 된 본 발명은 밸브몸체(31) 내부에 불규칙하면서도 강한 유체가 화살표 방향으로 흐를 때 강한 유체의 압력에 의하여 씰디스크(35)는 상.하 로 움직이면서 유체의 흐름량을 조절하게 되어 불규칙하게 흐르던 유체가 스므스(SMOOTH)하게 흐르게 된다.In the present invention as described above, when the irregular and strong fluid flows in the direction of the arrow in the valve body 31, the seal disk 35 moves up and down by the pressure of the strong fluid to control the flow rate of the fluid and flows irregularly. The fluid flows smoothly.

또한, 흘러갔던 유체가 정전으로 인하여 되돌아와 강한 수충격으로 강타할 때 고압의 유체는 카바(4) 하부에 수개의 구멍(34)으로 흘러 들어가 다이아후램(11)(12)이 위로 올라감으로 인해 밸브몸체(31) 내부의 유체는 화살표 반대 방향으로 약간의 유체가 흘러가게 되어 유체의 압력이 저하되어 강한 수충격이 발생하여도 본 발명의 고압 콘트롤밸브 보호는 물론, 같이 연결되어 있는 펌프, 밸브, 신축관, 역지변등도 자동으로 보호하게 된다.In addition, when the flowing fluid returns due to the power failure and struck with a strong water shock, the high-pressure fluid flows into the several holes 34 in the lower part of the cover 4 due to the diaphragm 11 and 12 being raised upward. The fluid inside the valve body 31 flows a little fluid in the direction opposite to the arrow so that the pressure of the fluid decreases and a strong water shock is generated, as well as the high pressure control valve protection of the present invention. It also automatically protects the expansion pipe, reverse displacement, etc.

발명의 구성 및 작용 누락Missing configuration and action of the invention

이와같은 본 발명은 펌프가 가동하여 유체를 관로내로 보낼시·불규칙한 유체를 스무스하게 흐르게 함은 물론 정전으로 인하여 펌프가 정지시 관성에 의하여 흘러갔던 유체가 되돌아와 강한 수충격이 강타 하여도 고압 콘트롤 밸브가 자동으로 압력을 조절하게 되어 같이 연결되어 있는 기자재등의 파손이 없어 펌프장의 안정성은 물론 매우 경제적인 효과가 있다.In the present invention, when the pump operates to send the fluid into the pipeline, the fluid flows smoothly, as well as the fluid flowing back by the inertia when the pump stops due to a power failure, and the high water pressure is controlled even when a strong water shock is struck. The valve automatically adjusts the pressure, so there is no damage to the equipments connected together, so the stability of the pump station is of course very economical.
