The utility model discloses a wedge-shaped double-plate gate valve, which comprises a valve body, a seat, a valve plate, a stem, a valve cover and a handwheel. The valve body and the valve cover constitute a sealed inner chamber. A rubber ring is arranged between the valve stem and the valve body, and the upper end of the valve stem is connected with the handwheel. The lower end of the valve stem is connected with the valve plate in a clamp way, and the valve body passage is provided with the said rubber ring. A valve seat is composed of two sides of the valve plate and the valve seat. The two sealing faces of the valve seat and the valve plate are provided with a filter screen. The valve plate is symmetrically wedge-shaped, and the lower end face of the valve plate is smaller than the upper end face. The valve plate is internally provided with a magnetic holding plate frame. The gate valve has high sealing performance, and the connection between the two valve plates is firm and not easy to fall off. The filter mesh can effectively protect the internal parts of the gate valve and increase the service life of the gate valve.

一种楔型双阀板闸阀
本技术具体涉及一种楔型双阀板闸阀。
技术介绍
闸阀是一个启闭件闸板,闸板的运动方向与流体方向相垂直,闸阀只能作全开和全关,不能作调节和节流,闸阀通过阀座和闸板接触进行密封,通常密封面会堆焊金属材料以增加耐磨性;楔型闸阀,是闸阀的一种,因其密封面与垂直中心线成某种角度即两个密封面成楔形而得名,一般情况下,两密封面成楔形的闸阀,密封面与垂直中心线的角度为2°52’、3°30’、5°、8°、10°等。现有的双阀板闸阀两阀板之间的连接方式不够完善,容易导致阀板脱落,而且楔型闸阀结构较复杂,内部零件较多,易被流体中的细小固体颗粒物磨损,且难以维修。
