Description
本發明係與閥有關,特別是有關於一種碟閥及其製造方法。The present invention is related to valves, in particular to a butterfly valve and its manufacturing method.
一般在控制管路之連通時,會使用碟閥來控制流體之流量。習知之碟閥包括一閥本體及一碟片,該閥本體設有一管道,該碟片沿該管道之直徑方向可轉動地設於該管道,藉由控制該碟片相對該管道偏轉之角度來控制該管道之連通程度。Generally, butterfly valves are used to control the flow of fluids when controlling the connection of pipelines. The conventional butterfly valve includes a valve body and a disc, the valve body is provided with a pipe, the disc is rotatably installed in the pipe along the diameter direction of the pipe, and the deflection angle of the disc relative to the pipe is controlled to achieve Controls the degree of connectivity of this pipe.
該碟閥的種類一般依其使用環境之溫度不同,大致可區分為低溫用(低於250度)及高溫用(高於250度)之兩種形態。其中高溫用的碟閥係於該管道周壁設置擋片以限制該碟片之轉動。然,現有之該擋片於加工時易因該管道之空間較小而導致加工不易、結構強度不足等問題,存在亟待改善之缺弊。The type of butterfly valve is generally divided into two types: low temperature (below 250 degrees) and high temperature (higher than 250 degrees) according to the temperature of its operating environment. The butterfly valve for high temperature is provided with a baffle plate on the peripheral wall of the pipeline to limit the rotation of the plate. However, the existing baffle plate is prone to problems such as difficult processing and insufficient structural strength due to the small space of the pipe during processing, and there are shortcomings that need to be improved urgently.
因此,有必要提供一種新穎且具有進步性之碟閥及其製造方法,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive butterfly valve and its manufacturing method to solve the above problems.
本發明之主要目的在於提供一種碟閥及其製造方法,結構強度佳且易於加工、製造。The main purpose of the present invention is to provide a butterfly valve and a manufacturing method thereof, which have good structural strength and are easy to process and manufacture.
