摘要阀门是在流体系统中,用来控制流体的方向、压力、流量的装置。阀门是使管道和设备内的介质(液体、气体、粉末)流动或停止,并能控制其流量的装置。阀门是管路流体输送系统中控制部件,它是用来改变通路断面和介质流动方向,具有导流、截止、节流、止回、分流或溢流卸压等功能。此处介绍的通海阀是安装于船舶空载水线以下的两舷、舭部或船底的进水阀,又称“海底阀”。它是通过手轮或甲板传动机构启闭的阀门。它是船舶内部管路系统与外界连接的重要装置,主要用于各管路海水注入和排出的控制及调节,其性能的好坏直接影响全船各系统甚至整个船舶的性能。48796

Abstract The valve is in fluid systems used to control fluid direction, pressure, flow devices. Valve piping and equipment within the media (liquid, gas, powder) flow or stop, and control the flow device.The valve control parts of the pipeline fluid transport system, which is used to change the channel section and flow direction of medium, persion, closed throttle-return shunt or overflow relief feature . Described here the sea valve is installed on both sides of the ship the following no-load waterline, the bilge or bottom of the inlet valve, also known as "submarine valve. It is the opening and closing the valve hand wheel or deck drive mechanism.It is an important device to ship internal piping system connected with the outside world, mainly for the pipeline water injection and exhaust control and adjust its performance of a direct impact on the whole ship system and even the performance of the entire ship. This article describes the design process of the sea valve, to determine the size of the parts of Solidworks 3D software Parametric modeling, as well as tooling design.
Keywords: parametric, valves, valve of the sea, the design of modeling;
