Abstract

The flow regulator includes as a tapping from the main pipe, an assembly of calibrated discharge conduits connected in parallel. Each calibrated conduit is fitted with a solenoid valve which is either fully open or fully closed, and a means of controlling the operation of the valves. The outflow of the valves is regrouped in a return collector which recycles the liquid into the main pipe. The valves are controlled by a microprocessor which can also control a main valve. The microprocessor program provides controlled diversion of the flow in the main pipe in order to obtain fine control of any alteration in the required delivery of liquid from the main pipe.

Description

냉각유체량 제어장치Cooling fluid flow control device

도면은 발명의 일실시예를 도시한 개략도Figure is a schematic diagram showing an embodiment of the invention

본 발명은 유체량 제어장치에 관한 것으로서, 특히 도관(conduit)내에서의 냉각유체량 제어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid amount control device, and more particularly to a cooling fluid amount control device in a conduit.

미합중국 특허 제4,308,881호와 동 제4,312,034호에는 강선 또는 강봉에서 요구되는 특성을 얻기 위하여 수피복층(water sheath)에 의한 냉각처리의 성공여부는 이같은 처리의 매개변수관리에 좌우된다고 기재되어 있다.U.S. Patent Nos. 4,308,881 and 4,312,034 describe the success of cooling by water sheath in order to obtain the properties required for steel wires or rods, depending on the parameter management of such treatments.

이같은 선행기술의 설비에 있어서, 주도관(主導管)내에서의 냉각유체량은 유체통호부위를 결정짓는 개방의 크기를 연속적으로 조정하기 위하여 모우터의 선택밸브로서 제어하는 것이 보통이다. 이와같은 배치로는 매개변수가 고정되어 있거나, 또는 단계적으로 변화할 경우 만족된 결과를 얻을 수 있다. 그러나 냉각조건이 급변하게 되는 경우에는 밸브감응에 대한 전달이 다소 지연됨으로서 유량전도(精度)에 나쁜 영향을 미치게 된다.In such prior art equipment, the amount of cooling fluid in the main pipe is usually controlled as a selector valve of the motor in order to continuously adjust the size of the opening that determines the fluid communication site. Such arrangements may yield satisfactory results if the parameters are fixed or change in stages. However, if the cooling conditions change suddenly, the transmission to the valve response is delayed slightly, which adversely affects the flow conductivity.

본 발명이 목적은 매우 빠른 유량을 조정함으로서 이와같은 단점을 극복할 수 있으며, 또 유량정도에 부작용을 미치지 않는 유량제어장치를 개발하는데 있다.An object of the present invention is to develop a flow control device that can overcome such disadvantages by adjusting the flow rate very fast, and does not adversely affect the flow rate.

본 발명에 따른 유량제어장치는 주도관에서 횡방향으로 설치한 수집배출도관에는 평행으로 다수 설치된 계측도관, 이들 검량도관에 각각에 설치된 솔레노이드밸브와, 이들 밸브의 개폐위치를 조절하는 미세조절장치로 구성된다. 따라서 현종기술을 사용해서 정밀하게 검량할 수 있는 이들 병렬 검량도관의 검량에 의해 유량을 선정한 단면부에 따른 증가량의 아주 정밀한 단위까지 조절할 수 있다. 서로 동일하거나 또는 서로 상이할 수도 있는 이들 검량도관은 냉각처리에 사용되는 유량을 주도관내에 형성시키기 위해 필요로 하는 도관수와 그 단면부에 따라 임의 형태로 사용할 수 있다.Flow control apparatus according to the present invention is a collection and discharge conduit installed in the transverse direction from the main pipe as a plurality of measurement conduits installed in parallel, solenoid valves installed on each of these calibration conduits, and a fine control device for adjusting the opening and closing positions of these valves It is composed. Therefore, by the calibration of these parallel calibration conduits, which can be precisely calibrated using current technology, it is possible to adjust the flow rate to the very precise unit of the increase according to the selected cross-section. These calibration conduits, which may be the same or different from each other, may be used in any form depending on the number of conduits and their cross-sections required to form a flow rate used for cooling treatment in the main pipe.

슬롭밸브(slop vavle)인, 솔레노이드밸브의 사용으로 밸브 감응지연이 실제로 전혀 없도록 할 수 있게 된다.The use of a solenoid valve, a slop valve, allows virtually no valve response delay.

조절수단으로는 밸브장애를 조작자에 의해 관측되거나 또는 처리 매개변수들로 부터 자동적으로 계산된 유량의 작용으로 저절할 수 있는 미세처리장치가 바람직하다.As a control means, a microtreatment device capable of controlling the valve failure by the action of the flow rate observed by the operator or automatically calculated from the processing parameters is preferred.

상기한 바와같이 감량도관은 주도관으로 부터 방출된 유체를 재순환시킬 수 있는 방출도관이다.As described above, the weight loss conduit is a discharge conduit capable of recirculating fluid discharged from the main conduit.

또한 검량도관은 주도관에 삽입된 수집배출도관내에 연결되는 것이 바람직하다. 이와같은 배열이 사용시에 특히 만족스러운 결과를 얻을 수 있음이 입증되었는데, 이같은 배열은 주도관내에 수압에 의한 난류(turbulance)가 전혀 발생하지 않기 때문이다.In addition, the calibration conduit is preferably connected in the collection and discharge conduit inserted into the main pipe. This arrangement has proved to be particularly satisfactory in use, since such an arrangement results in no turbulence caused by hydraulic pressure in the main pipe.

본 발명은 본 발명의 일실시예로 도시한 첨부도면과 다음 설명에 따라 보다 명백히 이해될 수 있다. 첨부 도면에는 환상공급실(2)의 중앙부를 통해 냉각하고저 하는 강봉(10)의 이동방향과 동일방향으로, 또는 반대 방향으로 순환하는 수피복층(도시않은)으로 둘러싸인 강봉(10)의 축을 따라 냉각도관(9)으로 냉각수를 공급하기 위한 주도관(1)이 상기 공급실(2)에 수직하방으로 설치하였으며, 이 주조관(1)에 수평방향으로 설치한 수집배출관(3)에는 솔레노이드밸브(5)를 각각 구비한 복수개의 병열로된 검량도관(4)을 배설하였다. 검량도관(4)의 방출수는 환수(環水) 코렉터(colletor) (6)내에서 수거하여 주도관(1)내로 물을 순환시킬 수도 있다.The invention can be more clearly understood according to the accompanying drawings and the following description which shows one embodiment of the invention. In the accompanying drawings, cooling along the axis of the steel rod 10 surrounded by a coating layer (not shown) circulating in the same direction as the moving direction of the steel rod 10 to be cooled through the central portion of the annular supply chamber 2 or in the opposite direction. A main pipe 1 for supplying cooling water to the conduit 9 is installed vertically downward in the supply chamber 2, and the collection discharge pipe 3 installed horizontally in the casting pipe 1 has a solenoid valve 5 Calibrated conduit 4, which consists of a plurality of parallel lines, each of which was provided with). The discharged water from the calibrated conduit 4 may be collected in a return collector 6 to circulate the water into the main pipe 1.

상기 솔레노이드밸브(5)는 미세처리장치(7)로서 조절되며, 이 미세처리장치(7)는 또한 수집배출관(3)의 인입구로 부터 냉각유체의 이동방향으로 상류에 해당되는 주도관(1)내에 위치한 슬롭밸브(slop valve)(8)를 제어할 수도 있다.The solenoid valve 5 is regulated as a microprocessor 7, which microprocessor 7 also corresponds to the upstream tube 1 upstream in the direction of movement of the cooling fluid from the inlet of the collection and exhaust tube 3. It is also possible to control a slop valve 8 located within.

본 발명의 실시예에 따른 작동은 다음과 같다. 냉각수 공급용 주도관(1)의 치수는 주어진 물의 유입압(통상 7 내지 10바아)에서 냉각도관(9)내에서의 수피복층의 적당한 속도를 한편 냉각도관(9)내에서 최대유속을 갖도고록 설계한다.Operation according to an embodiment of the present invention is as follows. The dimensions of the main conduit (1) for supplying the cooling water are such that at a given water inlet pressure (typically 7 to 10 bar), the appropriate velocity of the sheath layer in the cooling conduit (9) is achieved while the maximum flow velocity in the cooling conduit (9) is achieved. Design.

상기와 같은 조건하에서, 솔레노이드밸브(5)는 통상 폐쇄된 상태에서는, 미세처리장치(7)는 냉각도관(9)내의 물의 유속을 필요한 양으로 감소시키기 위해서 하나, 또는 그 이상의 솔레노이드밸부(5)로 개방을 조정하게 된다. 다른 실시예에서는 솔레노이드밸브(5)가 통상 개방된 상태에서는, 냉각유체의 유량을 증가시킬 필요가 있는 경우에만 이들 솔레노이드밸브(5)로 개방을 조정하게 된다.Under the above conditions, in the state in which the solenoid valve 5 is normally closed, the microprocessor 7 is provided with one or more solenoid valve portions 5 in order to reduce the flow rate of water in the cooling conduit 9 to the required amount. To adjust the opening. In another embodiment, when the solenoid valve 5 is normally open, the opening is adjusted by these solenoid valves 5 only when it is necessary to increase the flow rate of the cooling fluid.

상기한 2개의 실시예에서 2가지 형태를 조합하여 사용할 수 있음을 쉽게 이해할 수 있다. 이들 실시예의 선택에 있어서 통상 폐쇄된 형태의 밸브는 폐쇄조작이 보다 빠르며, 또 통상 개방된 형태의 밸브는 개방조작이 보다 빠르다는 사실에 입각해서 적합한 밸브형태에 따라서 선택된다.It can be easily understood that the two embodiments can be used in combination in the two embodiments described above. In the selection of these embodiments, normally closed valves are quicker to close, and normally open valves are selected according to the appropriate valve type, based on the fact that opening is faster.

본 발명은 냉각수 또는 수피복층의 이동방향을 따라 진행하는 급속제품의 냉각에 사용할 수 있을뿐만 아니라 액체와 같은 비압축성유체의 흐름이 급변하거나 또 정밀을 요하는 기타분야에서 사용될 수도 있다.The present invention can be used not only for the cooling of rapid products progressing along the direction of movement of the cooling water or the coating layer, but can also be used in other fields where the flow of incompressible fluids such as liquids changes rapidly or requires precision.
