Description

웨퍼형 벤츄리 콘 메타Wafer type Venturi cone meta
본 발명은 웨퍼형 벤츄리 콘 메타에 관한 것으로서, 보다 상세하게는 조립성이 향상되고, 제품의 신뢰성이 향상된 웨퍼형 벤츄리 콘메타에 관한 것이다.The present invention relates to a wafer type venturi cone meta, and more particularly, to a wafer type venturi cone meter with improved assembly properties and improved product reliability.
일반적으로 수도와 같은 청수(淸水) 분야 또는 저점도 유체의 유량 측정에는 웨퍼형 벤츄리 콘 메타가 사용되고 있다. 기존의 웨퍼형 벤츄리 콘 메타는 벤츄리 콘을 구비하고, 벤츄리 콘은 완만한 경사로 이루어지는 뾰족한 끝단부가 고압측 또는 유입부쪽을 향하고 타측에는 벤츄리 콘을 지지하는 막대가 부착되고 상기 막대에는 날개가 고정되며 상기 날개의 끝단부는 삽입홈에 끼워져 고정되는 구조로 이루어진다.Generally, a wafer type venturi cone meta is used for the measurement of flow rate in a fresh water field such as tap water or a low viscosity fluid. The conventional wafer type venturi cone meta has a venturi cone, and the venturi cone has a pointed end having a gentle inclination toward the high pressure side or the inflow side, and a rod supporting the venturi cone is attached to the other side, and a wing is fixed to the rod. End portion of the wing is made of a structure that is fitted into the insertion groove is fixed.
그러나 상기와 같은 종래 구조의 웨퍼형 벤츄리 콘 메타는 벤츄리 날개와 콘이 일체로 이루어진 이른바 어셈블리 단위로 교체가 이루어져야 하는데, 실제 현장에서는 다양한 조건에 따라 콘의 사이즈를 변경하면서 튜닝(tunning)하여야 하므로 그 작업을 위하여 요구되는 어셈블리의 경우의 수가 많다는 문제점이 있다. 또한 날개(104)의 두께를 줄이는데 한계가 있어 와류가 심하게 발생되고 후단부의 유속에 방해가 되어 경우에 따라 유량 측정값이 정확하지 않을 수 있다는 문제점이 있다. However, in the conventional structure of the wafer-type Venturi cone meta as described above, the Venturi wing and the cone have to be replaced by a so-called assembly unit, and in practice, the cone must be tuned while changing the size of the cone according to various conditions. The problem is that the number of assemblies required for the task is large. In addition, there is a limit in reducing the thickness of the wing 104, so that the vortex is severely generated and the flow rate of the rear end is hindered, there is a problem that the flow rate measurement value may be incorrect in some cases.
상기와 같은 문제점을 해결하기 위해 본 출원인은 전체 어셈블리가 아닌 콘만의 교체 테스트 및 유지보수가 용이하도록 유량계 본체에 형성된 가이드홈에 날개부의 날개를 끼워 조립하는 웨퍼형 벤츄리 콘 메타에 대한 등록특허 10-0915088호를 출원하였다. 그러나 이러한 웨퍼형 벤츄리 콘 메타는 In order to solve the above problems, the present applicant has a wafer-type Venturi cone meta for assembling the wing of the wing to the guide groove formed in the flowmeter body to facilitate replacement test and maintenance of the cone only, not the entire assembly. 0915088 is filed. However, these wafer type Venturi cone meta
가이드홈에 날개를 삽입하여 고정하는 경우, 다수개의 날개 끝단이 정확하게 가이드홈에 삽입되도록 하기 위해서는 날개의 끝단과 가이드홈을 정밀가공해야 하므로 제작이 어렵고 조립식 조립불량이 발생되는 문제점이 있다. 즉, 날개와 가이드홈 간의 가공 공차가 작으면 날개를 가이드홈에 삽입하는데 어려움이 있고, 날개와 가이드홈 간의 가공 공차가 크면 유격에 의해 작동중에 진동 및 소음이 발생되는 문제점이 있다. 웨퍼형 벤츄리 콘 메타가 장착되는 부위는 유체에 의한 저항이 크기 때문에 유격에 의한 진동으로 인해 피로하중이 누적되어 손상될 위험성도 있다.In the case of inserting and fixing the wings in the guide grooves, in order to accurately insert the plurality of wing ends into the guide grooves, it is difficult to manufacture the assembly assembly defects because the end and the guide grooves must be precisely processed. That is, when the machining tolerance between the wing and the guide groove is small, it is difficult to insert the blade into the guide groove, and when the machining tolerance between the wing and the guide groove is large, there is a problem that vibration and noise are generated during operation due to play. The site where the wafer type venturi cone meta is mounted has a high resistance due to the fluid, and there is also a risk that fatigue load accumulates and damages due to vibration caused by play.

In addition, the wing member 30 is made of an inclined cross-sectional shape or streamlined cross-sectional shape to minimize the resistance element of the fluid flowing inside to allow the fluid to flow smoothly. Coupling portion 31 also has an inclined cross-sectional shape to minimize the resistance element of the fluid flowing inside to allow the fluid to flow smoothly. As such, when the resistance element to the flow of the fluid is removed, the flow measurement accuracy of the wafer type venturi cone meta is improved.
또한, 벤츄리 콘(20)이 결합부(31)에 탈부착 가능하도록 나사결합되는 구조로 구성되는 경우에는 플랜지부재(40)의 교체와 함께 벤츄리 콘(20) 만의 교체가 가능하므로, 도관의 크기는 동일하나 벤츄리 콘(20) 만의 형상을 변경하고자 하는 경우에도 활용 가능하고, 설치되는 도관의 크기가 변경되는 경우, 벤츄리 콘(20)은 동일하게 사용하면서 플랜지부재(40)만을 교체하는 것이 가능하므로 그 활용성이 향상된다. 즉, 플랜지부재(40)와 벤츄리콘(20)을 각각 공용화 시키는 것이 가능하므로 측정환경에 따른 설치될 수 있는 경우의 수가 증가되므로 제품의 신뢰성이 향상된다.In addition, when the venturi cone 20 is configured to be screwed so as to be detachable to the coupling portion 31, the venturi cone 20 can be replaced with the replacement of the flange member 40, so that the size of the conduit It is the same but can be utilized even if you want to change the shape of the venturi cone 20 only, and if the size of the conduit to be installed is changed, the venturi cone 20 can be used to replace only the flange member 40 while using the same Its usability is improved. That is, since the flange member 40 and the venturicon 20 can be used in common, the number of cases that can be installed according to the measurement environment is increased, thereby improving product reliability.
