이하 본 발명의 실시 예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다. 또한 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명은 생략한다.Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

도면에서와 같이 본 발명의 오리피스(10)는 관(20)과 관(20) 사이에 설치되는 몸체(11)와, 상기 몸체(11)에 수평방향으로 형성되어 상기 관(20)과 관(20)이 연통되도록 하고 오일의 유동 단면적을 변화시킬 수 있도록 하는 2개 이상의 유량조절홀(12)을 포함하여 구성된다.As shown in the drawing, the orifice 10 of the present invention has a body 11 installed between the tube 20 and the tube 20, and formed in the horizontal direction on the body 11, the tube 20 and the tube ( 20 and two or more flow control holes 12 to allow for communication and to change the flow cross-sectional area of the oil.

상기 관(20)은 이웃하는 관(20)을 연결하기 위해서 플랜지(21)가 형성되어 있고, 이 플랜지(21)들 사이에 오리피스(10)가 끼워지며 플랜지(21)에 형성되는 볼트홀(22)을 통해 체결볼트(도시없음)를 체결하여 관(20)과 관(20) 사이에 오리피스(10)를 설치한다.The pipe 20 has a flange 21 is formed to connect the neighboring pipe 20, the orifice 10 is sandwiched between the flange 21 and the bolt hole formed in the flange 21 ( 22) through the fastening bolt (not shown) to install the orifice 10 between the tube 20 and the tube 20.

한편 상기와 같이 오리피스(10)에 형성되어 있는 다수의 유량조절홀(12)의 면적의 합은 오리피스(10) 가공시 설계상에서 오리피스(10)에 요구되는 유량조절홀(12)의 면적과 동일하게 형성한다.On the other hand, the sum of the areas of the plurality of flow control holes 12 formed in the orifice 10 as described above is equal to the area of the flow control holes 12 required for the orifice 10 in the design of the orifice 10 processing. Form.

즉 설계상에서 오리피스(10)에 형성하기 위해 요구되는 홀 사이즈를 계산한 후 유량조절홀(12)을 하나만 형성하는 대신 2개 이상의 유량조절홀(12)을 형성하되, 2개 이상의 유량조절홀(12) 면적의 합은 설계상에서 유량조절홀(12)을 하나만 형성하였을 경우와 동일하게 형성하여 하는 것이다.That is, instead of forming only one flow control hole 12 after calculating the hole size required for the orifice 10 in the design, two or more flow control holes 12 are formed, but two or more flow control holes ( 12) The sum of the areas is the same as in the case where only one flow control hole 12 is formed in the design.

이렇게 다수의 유량조절홀(12)들의 면적의 합이 설계상에서 유량조절홀(12)을 하나만 형성하였을 경우와 동일하게 형성함으로써 오리피스(10)를 통한 유체의 배압증가 효율이 유량조절홀(12)을 하나만 형성하였을 경우와 동일한 효과를 나타내면서 오리피스(10)를 통과한 유체의 압력을 분산시켜 침식을 방지할 수 있게 되는 것이다.As such, the sum of the areas of the plurality of flow control holes 12 is the same as in the case where only one flow control hole 12 is formed in the design, so that the back pressure increase efficiency of the fluid through the orifice 10 is increased. It will be able to prevent the erosion by dispersing the pressure of the fluid passing through the orifice 10 while showing the same effect as when only one is formed.

한편 상기 오리피스(10)의 일측에는 관(20)과 관(20) 사이에 조립이 용이하도록 하고, 오리피스(10)나 유량조절홀(12) 크기 등의 정보가 기재될 수 있도록 평판형태의 손잡이(13) 더 형성된다.On the other hand, one side of the orifice 10 to facilitate the assembly between the tube 20 and the tube 20, the handle of the flat form so that information such as the orifice 10 or the flow control hole 12 size can be described (13) is further formed.

이와 같은 구성되는 본 발명은 관(20) 내부를 흐르는 유체가 오리피스(10)에 형성되어 있는 다수의 유량조절홀(12)을 통과하면서 압력이 분산되어 오리피스(10) 후방의 어느 한 부분에 집중적이 부하가 발생되지 않게 된다.According to the present invention constituted as described above, the fluid flowing in the pipe 20 passes through a plurality of flow rate adjusting holes 12 formed in the orifice 10 so that the pressure is dispersed and concentrated in any part of the rear of the orifice 10. This load will not occur.

따라서 오리피스(10) 후방에 엘보나 밸브 등의 배관 부속품을 설치하여도 침식에 의한 부작용이 발생되지 않게 된다.
Therefore, even if a pipe fitting such as an elbow or a valve is installed behind the orifice 10, side effects due to erosion are not generated.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
