본 고안은 설치장소에 구애되지 않고 설치할 수 있게하는 동시에 압력을 받는 면적이 개폐시에 항상 일정하게하여 개폐작용이 원활하게 하는 동시에 진동 및 소음을 방지시켜 기기의 손상과 밸브의 손상을 적게한 압력조정밸브에 관한 것으로 종래의 배런스 피스톤형 압력 조정밸브는 주압력 통로에만 설치해야하는 문제점이 있었을뿐 아니라 개폐시의 압력을 받는 면적이 서로 달라 진동이 발생되는 동시에 소음이 발생하여 기기의 손상 및 밸브의 손상을 주는 문제점이 있었다.This design makes it possible to install regardless of the installation place, and the area under pressure is always constant during opening and closing, so that the opening and closing action is smooth, and vibration and noise are prevented to reduce the damage of the device and the valve. It is related to the control valve, and the conventional balance piston type pressure control valve not only has to be installed in the main pressure passage, but also has a different area under pressure during opening and closing, which causes vibration and noise. There was a damaging problem.

본 고안은 이와 같은 문제점을 적게 한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention will be described in detail by the accompanying drawings to reduce such problems as follows.

주입구(a)와 배출구(b)를 뚫은 실린더동체(1)내에 중앙통공(2)을 갖은 피스턴형 개폐변(3) 삽입시켜 코일스프링(4)으로 탄지시키고 상부에 소형 실린더(5)를 설치하여 압력조정개패변(6)을 삽입시켜 코일스프링(7)으로 탄지되게 조정보울트(8)로 탄지시키고 하부실린더동체(1)와 유통되게 유통로(9)를 형성한 통상의 것에 있어서, 주입구(a)에 변좌(10)를 형성하여 역지변(11)을 설치하고 그 상면에 테이퍼면(A)을 같는 변좌(12)를 형성하여 피스턴형 개폐변(3)의 단무에 형성한 평면개폐부(3a)가 개폐케하고 상부에 설치된 소형실린더(5)에 테이퍼진변좌(5a) 조정 개폐변(6)의 단부에 형성한 평면개폐부(6a)가 개폐케 하고 유통로(13)에 별개의 유통로(14)로 연통되게 하여서된 것이다.A piston type opening / closing valve (3) having a central hole (2) is inserted into the cylinder body (1) through which the inlet (a) and the outlet (b) are inserted, which is held by the coil spring (4), and a small cylinder (5) is installed at the top. In the usual case of inserting the pressure regulating valve 6, the inlet is formed by the adjustment bolt 8 so as to be carried by the coil spring 7, and the flow path 9 is formed in circulation with the lower cylinder body 1. (a) the toilet seat (10) is formed, the reverse side 11 is provided, and the upper and lower sides of the tapered surface (A) to form a toilet seat (12) to form a planar opening and closing part formed on the end of the piston type opening side (3) Adjusting the tapered toilet seat 5a on the small cylinder 5 installed at the upper side of the cylinder 3a to open and close the flat opening / closing portion 6a formed at the end of the valve opening 6a. It is made to communicate with the flow path 14.

이상과 같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

주입구(a)로 유채를 공급시키면 주입구(a)에 형성한 변좌(10)에 설치된 역지변(11)을 밀고 들어가 평상시에는 실린더 동체(1)내에 삽입된 피스턴형 개폐변(3)에 뚫 은 중앙통공(2)을 통하여 상부에 설치한 소형실린더(5)와 연통시킨 유통로(9)로 들어가 테이퍼진 변좌(5a)를 개폐하는 조정개폐변(6)에 형성한 평면개폐부(6a)를 밀고 들어가 유통로(13)와 연통시킨 별개의 유통로(14)를 통하여 배출구(b)로 배출되는데 이때 테이퍼진 변좌(5a)에 조정개폐밸브(6)에 형성한 평면개폐부(6a)가 개폐하고 있기 때문에 열리기 시작할 때와 열린후에도 항상 일정면적에 유압이 작용되어 개폐작용이 원활하여 진동과 소음이 발생하지 않으며 주입구(a)로 공급되는 유채 압력기 높을 경우에는 제1도에서와같이 피스턴형 개폐변(3)을 밀어 올리면서 유체가 유입되는데 이때 역시 변좌(12)의 테이퍼면(A)에 피스턴형 개폐변(3)의 단부에 형성한 평면개폐부(6a)가 개폐하고 있어 열리기전이나 열린후에도 항상일정한 면적에 유압이 작용되므로 개폐작용이 원활하여 소음 및 진동이 발생되느 않으므로 기기 및 밸브의 손상을 적게하는 동시에 주입구(a)와 배출구(b)만을 형성하여 별개의 유통로(14)와 유통로(13)와 연관시키고 있어 종래와 같이 주압력통로에 설치하고 않고 어떤 장소에서나 설치가 가능하며벨브의 주입구(a)에 역지변(11)을 설치하였기 때문에 밸브내에 항상 기초압력을 유지시켜 주므로서 반복작용이 신속하면서도 원활하게 작동할 수 있는 이점이있다.When the rapeseed is supplied to the inlet opening (a), the stationary valve 11 installed in the toilet seat 10 formed in the inlet opening (a) is pushed in and is normally drilled into the piston type opening / closing valve 3 inserted into the cylinder body 1. The planar opening / closing part 6a formed in the adjustment opening / closing 6 which enters the flow path 9 which communicated with the small cylinder 5 installed in the upper part through the center hole 2, and opens and closes the tapered toilet seat 5a is opened. Pushed in and out through a separate flow passage 14 in communication with the flow passage 13 is discharged to the outlet (b) at this time, the flat opening and closing portion (6a) formed in the adjustment opening and closing valve (6) on the tapered toilet seat (5a) is opened and closed Therefore, when opening and after opening, the hydraulic pressure is always applied to a certain area so that the opening and closing action is smooth and vibration and noise are not generated. When the rapeseed pressure supplied to the injection port (a) is high, as in FIG. While the fluid flows in while pushing the opening / closing side (3) At this time, the planar opening / closing portion 6a formed at the end of the piston-type opening / closing edge 3 is opened and closed on the tapered surface A of the toilet seat 12, so that hydraulic pressure is always applied to a constant area before opening or after opening. Since it does not generate noise and vibration smoothly, it reduces the damage of equipment and valves and at the same time forms only the inlet (a) and the outlet (b) and is associated with the separate channel 14 and channel 13 as in the prior art. It can be installed in any place without installing in the main pressure passage, and since the reverse valve 11 is installed in the inlet (a) of the valve, it can keep the basic pressure in the valve all the time, so it can operate quickly and smoothly. There is an advantage.
