偏心半球閥使用的工作原理介紹

來源:http://www.szgotta.com.cn/ 日期:2023-11-01 發布人:admin
偏心半球閥的工作原理是通過旋轉半球閥芯來控制流體的流量和壓力。當半球閥芯旋轉時,流體會從閥門的進口流入半球閥芯的內部,然后通過半球閥芯的出口流出。半球閥芯的旋轉角度決定了流體的流量和壓力,因此可以通過控制半球閥芯的旋轉角度來實現流體的控制和調節。
The working principle of an eccentric hemisphere valve is to control the flow and pressure of the fluid by rotating the hemisphere valve core. When the hemispherical valve core rotates, fluid will flow from the inlet of the valve into the interior of the hemispherical valve core, and then flow out through the outlet of the hemispherical valve core. The rotation angle of the hemispherical valve core determines the flow rate and pressure of the fluid, so fluid control and adjustment can be achieved by controlling the rotation angle of the hemispherical valve core.
二、結構特點
2、 Structural characteristics
偏心半球閥的結構特點主要包括以下幾個方面:
The structural characteristics of eccentric hemisphere valves mainly include the following aspects:
1. 閥體:偏心半球閥的閥體通常采用球體結構,球體的一側是半球形的,另一側是圓形的。半球形的一側是閥門的進口,圓形的一側是閥門的出口。
1. Valve body: The valve body of an eccentric hemispherical valve usually adopts a spherical structure, with one side of the sphere being hemispherical and the other side being circular. The hemispherical side is the inlet of the valve, and the circular side is the outlet of the valve.

2. 半球閥芯:半球閥芯是偏心半球閥的核心部件,它的形狀類似于一個半球形的碗。半球閥芯的一側是凸出的,另一側是凹陷的。凸出的一側與閥體的半球形一側相對應,凹陷的一側與閥體的圓形一側相對應。
2. Hemisphere valve core: The hemispherical valve core is the core component of an eccentric hemispherical valve, and its shape is similar to a hemispherical bowl. One side of the hemispherical valve core is protruding, and the other side is concave. The protruding side corresponds to the hemispherical side of the valve body, and the concave side corresponds to the circular side of the valve body.
3. 傳動裝置:偏心半球閥的傳動裝置通常采用手動、電動或氣動傳動裝置。手動傳動裝置通常采用手輪或手柄,電動傳動裝置通常采用電機和減速器,氣動傳動裝置通常采用氣動執行器。
3. Transmission device: The transmission device of the eccentric hemisphere valve usually adopts manual, electric, or pneumatic transmission devices. Manual transmission devices typically use handwheels or handles, electric transmission devices typically use motors and reducers, and pneumatic transmission devices typically use pneumatic actuators.
4. 密封結構:偏心半球閥的密封結構通常采用軟密封或金屬密封。軟密封通常采用橡膠或聚四氟乙烯等材料,金屬密封通常采用不銹鋼或鈦合金等材料。
4. Sealing structure: The sealing structure of eccentric hemisphere valves usually adopts soft sealing or metal sealing. Soft seals typically use materials such as rubber or polytetrafluoroethylene, while metal seals typically use materials such as stainless steel or titanium alloy.
三、應用領域
3、 Application field
偏心半球閥廣泛應用于石油、化工、冶金、電力、水處理等行業,主要用于控制流體的流量和壓力。它的優點是結構簡單、操作方便、密封性好、耐腐蝕性強、使用壽命長等。在石油和化工行業中,偏心半球閥通常用于控制高溫、高壓、腐蝕性強的介質,如酸、堿、鹽等。在水處理行業中,偏心半球閥通常用于控制污水、廢水等介質的流量和壓力。
Eccentric hemispherical valves are widely used in industries such as petroleum, chemical, metallurgical, power, and water treatment, mainly for controlling fluid flow and pressure. Its advantages include simple structure, convenient operation, good sealing, strong corrosion resistance, and long service life. In the petroleum and chemical industries, eccentric hemisphere valves are usually used to control high temperature, high pressure, and highly corrosive media, such as acids, alkalis, salts, etc. In the water treatment industry, eccentric hemispherical valves are usually used to control the flow and pressure of media such as sewage and wastewater.
