본 발명은 유체의 압력에 비례하여 배출구가 좁아지기 때문에 그 유출 량이 조절되며, 유출의 유출 량이 정상적인 사용량을 초과하면 자동 차단되게 함으로써 수도관, 송유관, 가스관의 파손으로 인한 사고에 대처하면서 물이나 기름 가스가 유실되는 것을 예방할 목적으로 발명한 『유체의 압력에 의한 유출 량 조절과 유체 자동차단 방법』에 관한 것이다.According to the present invention, since the outlet is narrowed in proportion to the pressure of the fluid, the outflow amount is controlled, and when the outflow amount exceeds the normal amount of use, the outlet is automatically shut off to deal with an accident caused by water pipe, oil pipe, or gas pipe breakage. The present invention relates to a method for controlling the flow rate due to the pressure of the fluid and a method for blocking the fluid, which is invented to prevent the loss of oil.

본 발명은 유체의 압력에 비례하여 배출구가 좁아지기 때문에 그 유출 량이 조절되며, 유출의 유출 량이 정상적인 사용량을 초과하면 자동 차단되게 함으로써 수도관, 송유관, 가스관의 파손으로 인한 사고에 대처하면서 물이나 기름 가스가 유실되는 것을 예방할 목적으로 발명한 『유체의 압력에 의한 유출 량 조절과 유체 자동차단 방법』에 관한 것이다.According to the present invention, since the outlet is narrowed in proportion to the pressure of the fluid, the outflow amount is controlled, and when the outflow amount exceeds the normal amount of use, the outlet is automatically shut off to deal with an accident caused by water pipe, oil pipe, or gas pipe breakage. The present invention relates to a method for controlling the flow rate due to the pressure of the fluid and a method for blocking the fluid, which is invented to prevent the loss of oil.

종래의 각종 유체용(流體用) 개폐장치는 유체의 알력이 커지면 유출 량이 증가하고 유체의 압력이 작아지면 유출 량이 감소되기 때문에 발생되는 문제가 있었으며, 수도관이나 송유관 및 가스관이 파손되면 많은 물이나 기름 및 가스가 유실되며 이로 인한 손실은 물론 더 큰 사고나 피해가 발생하는 많은 문제가 있었다.Conventional fluid switchgear has a problem caused by the increased flow of fluid increases the flow rate and the decrease of the flow pressure when the pressure of the fluid decreases, a lot of water or oil if the water pipe, oil pipe and gas pipe is damaged And gas are lost and there are many problems in which the resulting loss, as well as larger accidents or damage occurs.

본 발명은 이 같은 문제를 근본적으로 개선하기 위해 유체의 압력이 커지면 유출구가 좁아지면서 유출 량을 감소시키며, 유체의 압력이 작아지면 유출구가 넓어지면서 유출 량을 증가시키도록 함으로써 유출 량을 균일하게 조절하도록 하였다.In order to fundamentally improve the problem, the present invention decreases the flow rate as the outlet becomes narrower as the pressure of the fluid increases, and evenly regulates the flow rate by increasing the flow rate as the outlet becomes wider when the pressure of the fluid decreases. It was made.

그리고 물이나 기름 및 가스를 정상적인 사용량 이상으로 사용하였을 때는 자동차단 됨으로써 그 과다 사용으로 인한 사고를 예방하며, 수도관이나 송유관 및 가스관이 파손되어 물이나 기름 및 가스가 유실되는 손실이나 그로 인한 피해를 예방하거나 최소화할 목적으로 발명한 것인데 첨부 도면에 의하여 상세히 설명하면 다음과 같다.And when water, oil and gas are used above normal usage, it is cut off to prevent accidents caused by overuse, and the loss of water, oil, and gas is lost due to damage of water pipe, oil pipe and gas pipe, and the resulting damage. It is invented for the purpose of minimizing or described in detail by the accompanying drawings as follows.

A valve 8 having a flange 5, a plurality of discharge holes 6, and a cylinder 7 formed inside the valve housing 1 in which three or more guide rods 4 are formed at the same interval at the upper end of the cylinder 1. ) And a spring (9) having elasticity corresponding to the hydraulic pressure of the fluid so that the size of the space (10) between the annular jaw (2) and the valve (8) is inversely proportional to the hydraulic pressure, The V-packing 11 is inserted into the circumferential groove of the flange 5 so that the fluid does not leak between the flange 5 and the inner wall of the control valve assembly 1.

[도 2b] 에서 보는 바와 같이 이는 [도 2a] 와 같은 구성에서 유도봉(4)대신 암나사관(12)을 형성시키고 이 관(12)에 배출관(13)을 결합하며, 조절밸브집(1)좌측 끝의 암나사(14)에 유입관(15)을 결합한다.As shown in FIG. 2b, this forms a female screw tube 12 instead of the induction rod 4 in the configuration as shown in FIG. 2a, and combines the discharge tube 13 with the tube 12, and adjusts the valve valve 1 ) Combine the inlet pipe 15 to the female screw 14 at the left end.

[도 2c] 에서 보는 바와 같이 밸브집(21)의 하단 내벽의 턱(40)에 오링(41)이 끼워진 [도 2a] 의 도면과 동일한 부품의 조절밸브집(1)하단이 접하도록 조절밸브집(1)을 장착하고, 밸브집(16)의 내벽에 형성된 환형턱(17)밑면에 패킹(18)을 끼운 다음 자루(19)가 형성된 밸브(20)가 유도봉(4)을 따라 작동하도록 조절밸브집(1)의 유도봉(4) 사이에 밸브(20)를 집어넣고, 밸브집(16)하단의 수나사(22)를 밸브집(21)상단의 암나사(23)에 결합하되 밸브집(16)상단의 암나사(24)에 결합한 나사관(25)의 환형턱(26)의 중심공(27)에 자루(19)를 집어넣고 그 상단 나사공에 원추형 밀대(28)의 나사(29)를 결합한다.As shown in FIG. 2C, the lower end of the valve housing 21 has an o-ring 41 fitted in the jaw 40 of the lower part of the same valve as shown in [FIG. 2A]. The house 1 is mounted, the packing 18 is inserted into the bottom of the annular jaw 17 formed on the inner wall of the valve house 16, and the valve 20 on which the bag 19 is formed is operated along the guide rod 4. The valve 20 is inserted between the guide rods 4 of the control valve housing 1 so that the male screw 22 at the bottom of the valve housing 16 is coupled to the female screw 23 at the top of the valve housing 21. The bag 19 is inserted into the center hole 27 of the annular jaw 26 of the screw tube 25 coupled to the female screw 24 on the upper end of the house 16, and the screw of the conical push rod 28 is inserted into the upper thread hole. 29).

나사관(25)상단의 요홈에 끼운 오링(30)이 방수관(31)의 내벽에 밀착되면서 유체가 새지 않고 오르내릴 수 있도록 구성한다.The O-ring 30 inserted into the groove of the upper end of the screw tube 25 is in close contact with the inner wall of the waterproof tube 31 so that the fluid can rise and fall without leaking.

나사관(25)상단의 암나사(32)에 전기절연체 마개(33)를 결합하여 유체가 새지 않도록 하되 이 전기절연체 마개(33)에는 전기도체로 구성된 탄성편(34)(35)이 분리된 채 고정되며, 그 상단을 전원에 연결할 수 있는 코드에 연결하고, 탄성편(34)에 전류가 흐르면 발신되는 공지의 발신기(44)가 장착되어 있다.Couple the electrical insulator stopper 33 to the female screw 32 on the upper end of the screw tube 25 so that no fluid leaks. The elastic insulator stopper 33 has elastic members 34 and 35 separated from each other. It is fixed, and the upper end is connected to a cord that can be connected to a power source, and a known transmitter 44 which is transmitted when current flows in the elastic piece 34 is mounted.

밸브(20)와 패킹(18) 사이의 공간(45)이 배출구(36)보다 클 때는 유체가 정상으로 배출되더라도 밸브(20)의 작동이 없지만 밸브(20)와 패킹(18) 사이의 공간(45)이 배출구(36)보다 작을 때는 유체가 정상으로 배출되더라도 밸브(20)가 패킹(18)에 밀착되도록 구성해야 한다.When the space 45 between the valve 20 and the packing 18 is larger than the outlet 36, there is no operation of the valve 20 even if the fluid is discharged normally, but the space between the valve 20 and the packing 18 ( When 45) is smaller than the outlet 36, the valve 20 should be in close contact with the packing 18 even if the fluid is discharged normally.

환형턱(17)의 배출구(36)에서 배출된 유체가 배출될 배출관(37)의 나사관(38)에 배출관(39)을 연결하며 배출관(39)에는 다양한 유체사용 개폐장치가 장착된다.The discharge pipe 39 is connected to the screw pipe 38 of the discharge pipe 37 to discharge the fluid discharged from the discharge port 36 of the annular jaw 17, and the discharge pipe 39 is equipped with various fluid use opening and closing devices.

밸브집(21)하단의 유입관(42)에는 유체의 공급관(43)을 결합하며 이 공급관(43)은 수원이나 유류 및 가스 저장탱크에 연결되어 물이나 유류, 가스를 공급한다.The supply pipe 43 of the fluid is coupled to the inlet pipe 42 at the bottom of the valve housing 21, and the supply pipe 43 is connected to a water source, an oil, and a gas storage tank to supply water, oil, and gas.

[도 2d] 에서 보는 바와 같이 이 도면은 [도 2c] 도면 중 밸브(20)를 통과하는 횡단면을 도시한 도면으로서 밸브집(21)의 내벽과 밸브(20) 사이의 공간(46)으로 유출되는 유체가 배출구(36)로 유출되는 유체보다 많도록 밸브집(21)의 내경과 밸브(20)의 외경 및 유도봉(4)의 크기를 검토하여 제작해야 한다.As shown in FIG. 2D, this figure shows a cross section through the valve 20 in FIG. 2C and flows out into the space 46 between the inner wall of the valve assembly 21 and the valve 20. The inner diameter of the valve assembly 21, the outer diameter of the valve 20, and the size of the guide rod 4 should be manufactured so that the fluid to be discharged to the outlet 36 is larger than that.

이상과 같은 본 발명의 작용원리는 [도1a] [도1b] [도2a] [도2b] 에서 보는 바와 같이 유체의 압력이 높아지면 밸브(8)와 원통(7) 및 후렌지(5)에 작용하는 유체의 압력에 의하여 스프링(9)이 수축되면서 밸브(8)가 환형턱(2)쪽으로 밀러며 공간(10)이 좁아지기 때문에 유체의 압력이 높아지더라도 그 배출량은 동일한 상태로 유지된다.As described above, the operating principle of the present invention is as shown in Figs. 1a, 1b, 2a, 2b, and the like. When the pressure of the fluid is increased, the valve 8, the cylinder 7, and the flange 5 are applied. As the spring 9 is contracted by the pressure of the working fluid, the valve 8 is pushed toward the annular jaw 2 and the space 10 is narrowed, so that the discharge amount remains the same even if the pressure of the fluid is increased.

이와는 반대로 유체의 압력이 낮아지면 밸브(8)와 원통(7) 및 후렌지(5)에 작용하는 유체의 압력이 감소되면서 스프링(9)이 늘어나기 때문에 밸브(8)가 환형턱(2)에서부터 멀어지면서 공간(10)이 더 넓어지므로 유체의 압력이 낮아지더라도 그 배출량은 동일하게 유지된다.On the contrary, when the pressure of the fluid decreases, the valve 8 extends from the annular jaw 2 because the spring 9 increases while the pressure of the fluid acting on the valve 8, the cylinder 7 and the flange 5 decreases. As the space 10 becomes farther away, the discharge remains the same even if the pressure of the fluid is lowered.

따라서 공간(10)이 유체의 압력에 따라 신축되면서 유체의 압력에 관계없이 유체의 배출량에 큰 변동 없이 동일하게 유지한다.Therefore, the space 10 is stretched according to the pressure of the fluid and remains the same without significant change in the discharge of the fluid regardless of the pressure of the fluid.

[도 2c] 에서 보는 바와 같이 공급관(43)에서 공급된 유체가 밸브(8)와 원통(7) 및 후렌지(5)에 압력을 가하지만 스프링(9)에 의하여 탄지되어 있기 때문에 그 유압에 관계없이 공간(10)이 신축하면서 일정량의 유체가 공급된다.As shown in FIG. 2C, the fluid supplied from the supply pipe 43 pressurizes the valve 8, the cylinder 7, and the flange 5, but is supported by the spring 9 so as to relate to the hydraulic pressure. The space 10 is expanded and supplied with a certain amount of fluid.

이와 같이 일정량의 유체가 공급됨에 따라 유도봉(4)사이에 생긴 공간으로 배출되는 유체가 배출구(36)를 지나 배출관(37)에 장착된 개폐장치를 완전히 열었을 때 배출되는 총량보다 많기 때문에 밸브(20)에는 아무런 영향을 주지 않고 정상으로 배출된다.As a certain amount of fluid is supplied, the fluid discharged into the space formed between the guide rods 4 is larger than the total amount discharged when the opening and closing device mounted on the discharge pipe 37 is completely passed through the discharge port 36. 20) discharged to normal without any effect.

그러나 배출구(36)를 지난 유체가 통과할 배출관(37)이나 나사관(38) 및 배출관(39)의 일부가 파열되면서 다량의 유체가 배출될 경우 밸브(20)를 경유하는 유체의 유속이 빨라지며 유압이 높아지므로 밸브(20)가 패킹(18)에 밀착되면서 배출구(36)가 완전 폐쇄되는 까닭에 유체가 배출구(36)를 통과하지 못하고 완전 차단된다.However, when a large amount of fluid is discharged while part of the discharge pipe 37 or the screw pipe 38 and the discharge pipe 39 through which the fluid passing through the discharge port 36 passes, the flow rate of the fluid passing through the valve 20 is high. As the hydraulic pressure is increased and the valve 20 is in close contact with the packing 18, the outlet 36 is completely closed and the fluid does not pass through the outlet 36 and is completely blocked.

이와 동시에 원추형밀대(28)가 탄성편(35)을 탄성편(34)쪽으로 밀어주기 때문에 탄성편(35)이 탄성편(34)에 접하면서 탄성편(34)에 장착된 발신기(44)에서 발신되므로 밸브(20)에 의해 배출구(36)가 밀폐되었음을 알려주게 된다.At the same time, since the conical push rod 28 pushes the elastic piece 35 toward the elastic piece 34, the elastic piece 35 is in contact with the elastic piece 34, and thus, in the transmitter 44 mounted on the elastic piece 34. Since the outlet 20 is sealed by the valve 20 will be informed.

이와 같은 상태에서 배출구(36)이하의 부품을 정상으로 복귀시킨 다음 나사관(25)을 돌리면서 환형턱(26)이 밸브(20)를 밀어내도록 하면 밸브(20)가 열리며 유체가 배출구(36)로 배출되는데 이 때 오링(30)에 의해 유체가 외부로 새지 않는다.In such a state, when the parts below the outlet port 36 are returned to the normal state and the annular jaw 26 pushes the valve 20 while turning the screw tube 25, the valve 20 opens and the fluid is discharged ( It is discharged to 36, but the fluid does not leak to the outside by the O-ring (30).

공간(45)을 충분히 확보하여 유체가 정상으로 배출될 때 밸브(20)가 닫히지 않도록 조정한 다음 나사관(25)을 원상복귀 시켰을 때 자루(19)의 성단에 장착한 원추형밀대(28)의 밑면이 환형턱(26)에 걸리면서 밸브(20)가 정상적인 위치에 머무르도록 조정한다.Adjust the valve 20 so as not to close when the fluid is discharged to a normal level by ensuring sufficient space 45, and then when the screw tube 25 is returned to its original position, The bottom surface is caught by the annular jaw 26 and the valve 20 is adjusted to stay in the normal position.

본 발명의 작용효과는 유압에 관게 없이 일정량이 유출되며 정상 이상의 유출 때는 자동으로 차단되는 작용효과가 있다.The effect of the present invention is a certain amount of outflow without regard to the hydraulic pressure and there is an effect of automatically shut off when the outflow over normal.
