Gate valve refers to the valve in which the closing member (gate) moves along the straight direction of the channel axis. It is primarily used as a cut-off medium on the pipeline, I .e. fully open or fully closed. In general, the gate valve can not be used as a conditioning flow. It can be applied to low temperature pressure can also be applied to high temperature and high pressure, and according to the different raw materials of the valve. But the gate valve is generally not used to transport mud and other media in the pipeline.
Strengths: small fluid resistance; small torque required for opening and closing; can be used in the ring network pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted; when fully open, the sealing surface is eroded by the working medium. Small; The structure is relatively simple, and the manufacturing process is better; The structure length is relatively short.
Defects: the overall size and opening height are large, and the installation space is also large. In the process of opening and closing, the sealing surface is relatively rubbed, and the abrasion is large, and even the scratch phenomenon is simply caused at high temperature. Generally, gate valves have two sealing surfaces, which add some difficulties to processing, grinding and repair. The opening and closing time is long.
Butterfly valve is a kind of valve that uses disc type opening and closing parts to open, close and adjust the fluid channel by reversing about 90 degrees. Advantages: simple structure, small size, light weight, low consumables, suitable for large-diameter valves; close quickly, low flow resistance; can be used with suspended solid particles of the medium, according to the strength of the sealing surface can also be used for powder and granular medium.
