Description

유압 자동 개폐 밸브Hydraulic auto shut off valve

제1도는 본 고안의 종단면도1 is a longitudinal cross-sectional view of the present invention

제2도는 작용상태의 단면도2 is a cross-sectional view of the working state

본 고안은 영구 자석과 코일 스프링을 이용하여 일정량이 배출되게 하거나 배출되는 유량을 측정할 수 있게 한 유압 자동 밸브에 관한 것으로, 종래의 유압 자동 밸브는 전자 회로 구성에 의하여 자동 개폐케하는 경우와 기구의 링크 작용에 의한 것들이 있었으나 이들은 그 구조가 복잡하고 오조작으로 인하 유량공급이 정확하지 못한 결점이 있었다.The present invention relates to a hydraulic automatic valve that allows a certain amount to be discharged or to measure the flow rate discharged by using a permanent magnet and a coil spring, the conventional hydraulic automatic valve is to open and close automatically by the electronic circuit configuration and mechanism There were some defects due to the link action, but they were complicated and the incorrect flow rate caused by incorrect operation.

본 고안은 이와 같은 결점을 적게 하기 위하여 동체 일측에 유압통을 형성하고 타측에 실린더를 형성하여 연관하고 그 내부에 돌출봉이 상부 통공에 삽설되게 단락 밸브를 수장하고 하부통공을 갖은 왕복피스턴을 삽설하여 하부에 탄발스프링으로 탄지하고 왕복피스턴의 상부에는 영구자석을 상하 조정할 수 있게 장설하여 단락 밸브의 테이퍼면을 갖은 돌출봉을 끌어 당겨 수로를 폐쇄케 하고 유압보다 탄발스프링과 상부에 장설된 영구자석의 자력이 약할 경우에 왕복피스턴이 하강되면 단락 밸브가 자중에 의하여 왕복피스턴에 형성된 실린더 하부로 떨어질 경우에 유체가 주연의 요구를 통하여 하부로 빠져나가 유압이 약화된 경우에 탄발스프링의 탄력에 의하여 왕복피스턴이 상승하여 자력이 강하게 작용하는 위치에 있을 경우 단락 밸브의 테이퍼진 돌출봉을 끌어당겨 폐쇄한 것으로 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to form a hydraulic cylinder on one side of the fuselage and to form a cylinder on the other side in order to reduce such a drawback, and to install a short-circuit valve so that the protruding rod is inserted into the upper through the inside and insert the reciprocating piston with the lower through The upper part of the reciprocating piston is mounted on the lower part, and the upper part of the reciprocating piston is installed so that the permanent magnet can be adjusted up and down, and pulls the protruding bar with the tapered surface of the short-circuit valve to close the waterway. When the reciprocating piston is lowered when the magnetic force is weak, when the short-circuit valve falls to the lower part of the cylinder formed on the reciprocating piston due to its own weight, the fluid flows downward through the demand of the peripheral edge, and when the hydraulic pressure is weakened, If the piston is in a position where the magnetic force is strong, the short-circuit valve Described in detail by the accompanying drawings that attracted close the protruding rods spread as follows.

동체(1)의 상부 일측에ㅐ 유통관(2)을 삽착한 유압통(3)을 형성하여 상부에서 통공(4)으로 연통되게 타측에 실린더(5)를 형성한 통상의 것에 있어서 실린더(5)의 내부에 탄발스프링(11)을 수장하고 그위에 상하통공(7)(9)을 뚫은 왕복피스턴을 장설하고 왕복피스턴 내부에 테이퍼면이 형성된 돌출봉(6)을 갖은 단락 밸브(8)를 수장하고 실린더(5)의 상부에는 상하 조정할 수 있게 하향돌출봉(12)을 돌설한 영구자석(13)을 장설하여 돌출봉(12)이 단락 밸브(8)에 돌설된 테이퍼면을 갖은 돌출봉(6)과 근접되게 하여서 된 것이다.In the conventional one in which the hydraulic cylinder 3 into which the flow pipe 2 is inserted into the upper one side of the body 1 is formed and the cylinder 5 is formed on the other side so as to communicate with the through-hole 4 from the upper portion, the cylinder 5 A short-circuit valve 8 having a tantalizing spring 11 installed therein, a reciprocating piston having perforated upper and lower through holes 7 and 9 thereon, and a protruding rod 6 having a tapered surface inside the reciprocating piston. And a permanent magnet 13 protruding the downwardly protruding rod 12 so as to be able to be adjusted up and down on the upper part of the cylinder 5, and the protruding rod having a tapered surface protruding the protruding rod 12 into the short circuit valve 8 ( It is made close to 6).

미설명부호 14는 퇴수로, 15는 필터이다.Reference numeral 14 denotes a drainage and 15 denotes a filter.

이상과 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

유통관(2)을 통하여 유체를 공급하면 필터(15)를 통과하여 동체(1)의 일측에 형성한 유압통(3)에 들어가 상부에서 연통된 통공(4)을 통하여 타측에 형성한 실린더(5)에 들어가 실린더(5)의 상부에 장설된 왕복피스턴(10)에 유압이 작용되어 왕복피스턴이 탄발스프링(11)을 압축하면서 하강하게 된다.When the fluid is supplied through the distribution pipe (2), the cylinder (5) formed on the other side through the through-hole (4) communicated from the top through the filter (15) formed in the hydraulic cylinder (3) formed on one side of the body (1) ), The hydraulic pressure is applied to the reciprocating piston 10 installed on the upper portion of the cylinder 5, and the reciprocating piston descends while compressing the ball shot spring 11.

이때 영구자석(13)의 하향돌출봉(12)과 단락 밸브(8)의 테이퍼면을 갖은 돌출봉(6)이 근접되어 자력이 유기되고 있던 것이 그 자력이 점차 약화될 때 단락 밸브(8)가 자중에 의하여 왕복피스턴(10)내에서 하강될 때 단락 밸브의 주벽에 형성한 요홈을 통하여 왕복피스턴(10)의 하부에 뚫은 통공(9)을 통하여 실린더 하부로 빠져 나와 퇴수로(14)로 배출된다. 이때 왕복피스턴(10)을 작용하고 있는 유압이 약화되면 탄발스프링(11)의 탄력보다 약하게 되어 탄발스프링의 탄력에 의하여 왕복피스턴(10)은 원위치로 상승하게 된다.At this time, when the downwardly protruding rod 12 of the permanent magnet 13 and the protruding rod 6 having the tapered surface of the short circuit valve 8 are close to each other and the magnetic force is induced, the short circuit valve 8 is gradually weakened. Is lowered in the reciprocating piston 10 by its own weight, exits to the lower part of the cylinder through the through hole 9 drilled in the lower part of the reciprocating piston 10 through the groove formed in the main wall of the short-circuit valve, and exits to the discharge path 14. Discharged. At this time, when the hydraulic pressure acting on the reciprocating piston 10 is weakened, it becomes weaker than the elasticity of the tanval spring 11, and the reciprocating piston 10 is raised to its original position by the elasticity of the tanval spring.

이때 영구자석(13)의 자력이 단락 밸브(8)의 테이퍼면을 갖은 돌출봉(6)에 미치게 되어 단락 밸브(8)가 상승하면서 왕복피스턴(10)의 상부통공(7)을 막아주게 된다.At this time, the magnetic force of the permanent magnet 13 extends to the protruding rod 6 having the tapered surface of the short-circuit valve 8 to block the upper through hole 7 of the reciprocating piston 10 as the short-circuit valve 8 rises. .

따라서 유압통(3)으로부터 유압이 가압되게 되는바, 일정압력이 가해지면 전술한바와 같은 작용으로 인하여 유체를 일정량 유출할 수 있게 한것으로 그 구조가 간단하여 고장율이 적고, 그 작용이 원활하여 정밀하게 유체를 공급시킬 수 있는 이점이 있는 것이다.Therefore, the hydraulic pressure is pushed from the hydraulic cylinder (3). When a certain pressure is applied, the fluid can be discharged by a certain amount due to the above-described action. The structure is simple, the failure rate is small, and the operation is smooth and precise. There is an advantage that can supply the fluid.
