Description
본 발명은 버터플라이 밸브의 부품 내구성 증대를 위한 코팅방법에 관한 것으로 절삭공구 및 정밀 부품 등의 내마모성 및 내열성을 높일 수 있도록 한 것이다.
The present invention relates to a coating method for increasing the durability of the butterfly valve to increase the wear resistance and heat resistance of cutting tools and precision parts.
일반적으로 버터플라이 밸브를 사용하다 보면 버터플라이 밸브의 사용처에 따라 부품의 마찰계수나 적용온도, 재질 등이 달라져 다양한 부품을 구비하여 수리 및 유지를 해왔다.
In general, when using a butterfly valve, the friction coefficient, application temperature, and materials of parts vary depending on where the butterfly valve is used, and various parts have been repaired and maintained.
상기와 같이 버터플라이 밸브의 구성이나 사용처에 따라 다양한 재질과 마찰계수를 가진 부품을 구비하기 위해 부품을 구비하고 있기 위한 공간과 그에 따른 비용이 많이 들었으며, 고온 고압용 밸브에서는 부품이 구동축에 융착되고, 부품의 마찰계수가 증가하여 베어링의 토크(TORQUE)가 상승하였으며, 버터플라이 밸브를 사용하다 마모되는 부품을 교체하기 위해 많은 시간과 비용이 소요되는 등의 문제점이 있었다.
According to the configuration and the use of the butterfly valve as described above, in order to have parts with various materials and coefficients of friction, there is a lot of space and cost accordingly. To increase the friction coefficient of the parts, the torque of the bearing was increased, and there was a problem such that it took a lot of time and money to replace the parts worn out by using the butterfly valve.
본 발명은 상기와 같은 문제점을 해결하기 위해 버터플라이 밸브의 구성 부품에 BALINIT 코팅을 하여 윤활성이 높고 내용착성이 우수하여 고온 고압의 상황에도 사용할 수 있는 부품을 형성한 것이다.
The present invention is to form a component that can be used even in a high temperature and high pressure conditions by applying a BALINIT coating to the component parts of the butterfly valve in order to solve the above problems, high lubricity and excellent weldability.
이와 같이 된 본 발명은 버터플라이 밸브의 구성 부품에 BALINIT 코팅을 함으로써 사용처에 따라 다양하게 요구되는 마찰계수나 재질에 상관없이 일괄적으로 BALINIT 코팅된 부품을 사용할 수 있어 내구성이 증대됨에 따라 수리 및 유지에 용이하며 경제적인 효과가 있는 것이다.
Thus, the present invention, by applying a BALINIT coating to the component parts of the butterfly valve can be used in a batch BALINIT coated parts irrespective of the friction coefficient or material that is variously required depending on the use, repair and maintenance as the durability is increased It is easy and economically effective.
본 발명의 기술적 목적은 버터플라이 밸브에 사용되는 정밀부품에 코팅층을 형성하여 기존의 부품보다 내용착석이 우수하고 윤활성이 높은 부품을 제공하는 것이다.
It is a technical object of the present invention to form a coating layer on a precision component used in a butterfly valve to provide a component having better lubricity and higher lubricity than a conventional component.
본 발명에 사용되는 코팅은 BALINIT코팅으로써, 상세한 내용은 아래와 같다.The coating used in the present invention is a BALINIT coating, details are as follows.
미세경도(HV0.05) 3300 ~ 3400Fine Hardness (HV0.05) 3300 ~ 3400
강에 대한 마찰계수(건식) 0.3 ~ 0.35Coefficient of friction for steel (dry) 0.3 to 0.35
코팅두께(㎛) 1 ~ 5Coating Thickness (㎛) 1 ~ 5
코팅온도(℃) < 500Coating temperature (℃) <500
최대적용온도(℃) 900Maximum application temperature (℃) 900
주요 특성 - 고온 경도 및 내산화성, 내마모성, 내용착성, 윤활성 우수
Main characteristics-Excellent high temperature hardness and oxidation resistance, wear resistance, welding resistance, lubricity
상기와 같은 방법으로 코팅을 하여 버터플라이 밸브의 내부 구성부품, 예를 들면 부시(bush)와 같은 부품에 적용을 하게 되면 아래의 조건과 같은 고온 고압용 버터플라이 밸브에서 사용 가능하게 되며,
When the coating is applied to the internal components of the butterfly valve, for example, such as a bush, the coating can be used in the high temperature and high pressure butterfly valve as described below.
적용온도 425℃Application temperature 425 ℃
요구 마찰계수 0.1 ~ 0.2
Required friction coefficient 0.1 to 0.2
이와 같이 BALINIT코팅을 할 때 부시의 구동축 접촉면이 코팅입자의 직진성에 의해 부시의 입구와 출구는 고르게 코팅되나 중간 부분으로 갈수록 코팅 두께가 얇아져 고르게 코팅되지 못하는 경향이 있어 부시의 길이를 입구와 출구의 지름과 일치시켜 코팅이 고르게 될 수 있도록하고, 한 번에 많은 양을 코팅할 수 있도록 하여 코팅 비용을 줄일 수 있도록 한 것이다.As described above, when the BALINIT coating is applied, the inlet and outlet of the bush are evenly coated due to the linearity of the coating particles, but the coating thickness becomes thinner toward the middle part, which makes it impossible to coat evenly. Matching the diameter allows the coating to be even and reduces the cost of coating by allowing a large amount to be coated at once.
