    • The present invention relates to an opening/closing valve for a sewer pipe of a manhole including: a main body (10) having a pair of semicircular flat body plates (11) spaced apart from each other by a given distance and a water-passing hole (110) formed at the center of each body plate (11); driving cylinders (20) rotatably shaft-supported against the top ends of both end portions of the main body (10); disk valves (30) disposed symmetrically between the body plates (11), each disk valve (30) being shaft-supported against the body plate (11) above the water-passing hole (110) at one end thereof and rotatably shaft-supported against the end portion of a piston (220) of the driving cylinder (20) at the other end thereof, so that the disk valves (30) are rotated correspondingly to each other around the end portions shaft-supported against the body plates (11) by means of the driving of the driving cylinders (20) to allow the water-passing holes (110) of the body plates (11) to be open/closed; and a flange pipe (40) connected on the outside of the body plate (11) disposed on one side of the main body (10) to a diameter size accommodating the diameter of the water-passing hole (110) thereinto and adapted to be coupled to a sewer pipe, whereby the installation height can be minimized to provide many conveniences in construction and the reduction in construction costs thereof.
    • 本发明涉及一种用于人孔的下水道管的开/关阀,包括:主体(10),具有一对彼此间隔一定距离的半圆形扁平板(11)和水流 形成在每个主体板(11)的中心的孔(110); 驱动气缸(20),其可旋转地轴支撑在主体(10)的两个端部的顶端上; 盘片阀(30)对称地设置在主体板(11)之间,每个盘阀(30)在其一端轴向支撑在通水孔(110)上方的主体板(11)上,并且可旋转地轴支撑 在其另一端处抵靠驱动气缸(20)的活塞(220)的端部,使得盘阀(30)围绕围绕主体板(11)的端部彼此相对旋转 )通过驱动气缸(20)的驱动,以允许主体板(11)的通水孔(110)打开/关闭; 以及连接在主体(11)的外侧的法兰管(40),其设置在主体(10)的一侧,直径尺寸容纳其中的通水孔(110)的直径,并适于 耦合到下水道管道,由此可以将安装高度最小化,从而在施工中提供许多便利以及降低其施工成本。
