According to the selection of control functions, various valves have their own functions, so pay attention to their corresponding functions when selecting.
The globe valve is one of the more widely used valves. The reason why it is popular is that the friction between the sealing surfaces during the opening and closing process is small, it is relatively durable, the opening height is not large, the manufacturing is easy, and the maintenance is convenient. Low pressure, but also suitable for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the disc and the sealing surface of the valve seat closely fit to prevent the medium from flowing.
The sealing principle of the wedge gate valve is based on the tight combination of the two sealing surfaces on the wedge gate and the two sealing surfaces on the valve body to achieve the seal. The purpose of using the wedge gate is to increase the auxiliary sealing load, so that the metal hard-seal wedge gate valve can seal both high medium pressure and low medium pressure. When closing, rotate the valve stem clockwise to make the sealing surface of the gate valve and the sealing surface of the valve body close to achieve a seal.
