Description

개폐도 센싱이 용이한 자동밸브{Auto valve easy to sensing of the switching degree}Auto valve easy to sensing of the switching degree}

본 발명은 증기발생장치에 적용되는 각종 관로의 개폐도를 세분화하여 정밀하게 센싱함과 동시에 이 센싱된 데이터를 컨트롤러에 피드백하여 밸브의 정확한 개폐도를 사용자가 쉽게 확인가능한 자동밸브에 관련한 기술분야에 속하는 발명이다.The present invention finely senses the opening and closing degree of the various pipelines applied to the steam generating device and at the same time feeds back this sensed data to the controller in the technical field related to the automatic valve that the user can easily check the accurate opening and closing of the valve The invention belongs.

일반적으로 물을 가열함에 따라 얻어지는 고압의 증기는 세탁소, 봉제공장, 취사장 등 여러 분야에서 널리 사용되고 있는데, 이러한 증기는 통상 증기발생장치에 의해 얻어진다.In general, the high-pressure steam obtained by heating the water is widely used in various fields, such as a laundry, a sewing factory, a kitchen, etc., and such steam is usually obtained by a steam generator.

이와 같은 증기발생장치는 증기를 발생, 저장하는 증기탱크 내에 수위를 감지하는 수위감지센서가 설치되어 상기 증기탱크에 설치된 히팅장치가 계속되는 가동에 의해 증발되어 나가는 증기량에 따라 수위가 줄어들면서 증기탱크의 수위가 설정된 최저수위에 도달하면 이를 수위감지센서가 감지하여 급수관에 설치된 급수제어밸브를 자동으로 개방함으로써 증기탱크로 급수가 이루어진다.Such a steam generator has a water level sensor installed in the steam tank for generating and storing steam, and the water level decreases according to the amount of steam evaporated by the continuous operation of the heating device installed in the steam tank. When the water level reaches the set minimum level, the water level sensor detects it and automatically opens the water supply control valve installed in the water supply line to supply water to the steam tank.

상기한 종래의 증기발생장치는 급수탱크가 증기탱크의 상측에 배치되어 상하 고도차에 의한 자연 압력으로 급수가 이루어지지 않는 이상, 상기 증기탱크에 새로운 물을 급수하기 위해서는 별도의 전기 모터펌프를 사용하여야만 한다.In the conventional steam generator, unless a water supply tank is disposed above the steam tank to supply water at a natural pressure due to an elevation difference, a separate electric motor pump must be used to supply new water to the steam tank. do.

더욱이 상기 증기탱크는 높은 자체 압력을 유지함에 따라 급수탱크를 상측에 배치하더라도 급수가 원활하지 못하며, 이와 같은 문제점을 해소하기 위해서는 반드시 대용량을 갖는 모터펌프를 설비하여야만 하므로 이에 따른 설비비가 많이 소요될 뿐만 아니라 모터펌프의 기동 및 작동에 많은 전력이 사용되어 에너지의 효율성, 운용성이 저하되고, 유지관리비가 많이 드는 폐단이 있는 실정이다.Furthermore, even though the steam tank maintains its own high pressure, the water supply is not smooth even when the water supply tank is placed on the upper side, and in order to solve such a problem, it is necessary to install a motor pump having a large capacity. Since a lot of power is used to start and operate the motor pump, energy efficiency and operability are reduced, and maintenance costs are high.

이러한 문제점을 해소하기 위한 방안으로 본 발명의 출원인에 의해 선출원 된 특허출원 「제2009-31160호 명칭/ 증기발생기에 사용하는 고온 고압 고효율 급수장치」가 제안되고 있는 것으로, 상기한 선출원 발명은 스팀탱크 자체 발생 압력을 사용하여 물을 공급함으로써 급수 시에 증기 압력의 변화를 최소화하면서 적정한 수위 조절을 이루어 기기 전체적으로 에너지 손실을 최소화하는 유용한 효과를 제공한다.In order to solve such a problem, a patent application "No. 2009-31160 No./High-temperature high-pressure high-efficiency water supply device for use in a steam generator" proposed by the applicant of the present invention has been proposed. By supplying water using self-generated pressure, it provides a useful effect of minimizing the change in steam pressure during water supply, while ensuring proper level control to minimize energy losses throughout the unit.

그러나 상기한 선등록 발명을 포함하는 여타 모든 증기발생장치에 적용되는 자동밸브는 유로를 제어명령에 따라 자동으로 개폐한 후 개폐도를 정확하게 센싱하여 컨트롤러로 피드백하는 기능이 없어 밸브작동이 제대로 이루어졌는지의 여부를 확인할 수 없고, 이로 인해 정확한 유량을 단속하는 신뢰성이 저하됨은 물론 증기발생장치가 원활하게 가동하지 못하며, 사용자가 밸브의 개폐도 범위를 임의로 정확하게 설정할 수 없는 실정이다.However, the automatic valve applied to all other steam generators including the above-described invention has no function of automatically opening and closing the flow path according to the control command and accurately sensing the opening and closing feedback to the controller to ensure proper valve operation. It is not possible to check whether or not, and this causes a decrease in reliability of controlling the correct flow rate, as well as the steam generator does not operate smoothly, the user can not set the opening and closing range of the valve arbitrarily accurately.

이에 근자에 들어 개폐도의 정확한 센싱 및 피드백 기능을 구비한 일부의 자 동밸브가 개시되고 있으나, 구조가 매우 복잡하고 가격이 고가인 폐단이 있다.Accordingly, some auto valves have been disclosed that have accurate sensing and feedback functions of opening and closing degrees, but there are closed ends that are very complicated in structure and expensive.

본 발명은 상기한 과제를 해결하기 위한 수단으로 증기압력 공급관과 같은 관로에 설치된 볼밸브의 밸브축에 기어드모터의 작동에 따라 회전하는 밸브 구동축을 일체로 결합하고, 상기 밸브 구동축의 상단에는 연동 회전하는 센싱판을 설치하며, 상기 센싱판의 상, 하에는 포토센서를 설치하는 기술을 강구한다.The present invention is a means for solving the above problems is integrally coupled to the valve shaft of the ball valve installed in the pipeline such as steam pressure supply pipe in accordance with the operation of the geared motor integrally, the upper end of the valve drive shaft is interlocked rotation In order to install a sensing plate, a technique for installing a photosensor above and below the sensing plate is devised.

또한, 본 발명은 상기 밸브 구동축에 자성체를 설치하고, 상기 자성체를 감지하는 다수의 리드센서가 부착된 센서 홀더를 상기 밸브 구동축의 외측에 감싸도록 설치하는 기술을 강구한다.In addition, the present invention devises a technique for installing a magnetic material on the valve drive shaft, and to install a sensor holder with a plurality of reed sensors for sensing the magnetic material on the outer side of the valve drive shaft.

본 발명에 따르면, 밸브 구동축과 연동 회전하는 센싱판의 회전 값을 세분화하여 더욱 정밀화된 개폐도를 정확하게 센싱함은 물론 상기 밸브 구동축에 설치된 자성체의 회전 값은 별도의 리드센서가 세분화하여 정확하게 센싱함으로써 밸브의 정확한 개폐도를 컨트롤러에 피드백하여 상기 밸브가 제어명령에 따라 정확하게 작 동하였는지의 여부를 쉽게 확인할 수 있는 효과를 제공한다.According to the present invention, by subdividing the rotation value of the sensing plate to rotate in conjunction with the valve drive shaft to accurately sense the more precise opening and closing degree, as well as the rotation value of the magnetic material installed in the valve drive shaft by the separate reed sensor to accurately sense Feedback to the controller of the correct opening and closing of the valve provides an effect that can easily determine whether the valve is operated correctly according to the control command.

또한, 상기한 피드백 데이터를 이용하여 밸브의 개폐도 범위를 임의로 정확하게 설정하여 증기발생장치의 가동에 따른 효율성을 가일층 향상시키는 효과를 제공한다.In addition, by using the above feedback data to set the opening and closing range of the valve arbitrarily accurately, it provides an effect of further improving the efficiency according to the operation of the steam generator.

Even if the technical configuration of the valve (V) is different, the application object (type of pipe) is different from the scope of the present invention.

이러한 본 발명의 자동밸브(V)는 사각체의 밸브케이싱(10) 내부에 기어드모터(20)가 설치되고, 상기 기어드모터(20)의 모터축(21)에 설치된 헬리컬기어(22)는 밸브 구동축(30)의 상단에 설치된 헬리컬기어(22)와 치합 설치됨으로써 상기 기어드모터(20)의 회전동력은 기어조합을 통해 밸브 구동축(30)으로 원활하게 전달된다.The automatic valve (V) of the present invention is a geared motor 20 is installed in the valve casing 10 of the rectangular body, the helical gear 22 is installed on the motor shaft 21 of the geared motor 20 is a valve By being meshed with the helical gear 22 installed at the top of the drive shaft 30, the rotational power of the geared motor 20 is smoothly transmitted to the valve drive shaft 30 through the gear combination.

그리고 상기 밸브 구동축(30)은 증기압력 공급관(2), 급수관(3) 등과 같은 관로에 설치된 공지의 볼밸브(4)를 구동할 수 있도록 상기 볼밸브(4)의 밸브축(5)에 일체로 결합됨으로써 기어드모터(20)의 작동시 밸브 구동축(30) 및 볼밸브(4)의 밸브축(5)이 동시에 연동 회전하면서 각종 관로의 유로를 자유롭게 개폐할 수 있게 된다.In addition, the valve drive shaft 30 is integral to the valve shaft 5 of the ball valve 4 to drive a known ball valve 4 installed in a pipeline such as a steam pressure supply pipe 2, a water supply pipe 3, and the like.
