The utility model provides a flat steel valve, which effectively solves the problem that the torque of the traditional steel plate valve is too large and too large; the technical solution is that the shell is vertically placed, horizontal tubes are fixed on both sides of the shell, the flat tubes are connected with the shell cavity, and the flange plates coaxial with the flat tubes are fixed at the far end of the flat tubes. The lower end of the rotating worm wheel is fixed with a fan-shaped plate which can rotate with the worm wheel. The left and right end faces of the fan-shaped plate are closely contacted with the side wall of the shell. The fan-shaped plate has through holes which are coaxial with the flat tube and run through the left and right end faces of the fan-shaped plate. The shell has worm installed in the front and back directions and can rotate actively, and the worm meshes with the worm wheel. The structure of the utility model is ingenious and effectively reduces the opening. Or the torque needed in the closing process to avoid leakage as much as possible.

技术介绍
闸阀的启闭件是闸板,通过对闸板的控制来达到阀门的全开或全关。现有的闸阀具有流动阻力小,形体结构简单,适用范围广等优点,被广泛的应用在各行各业。然而在现有的闸阀中,闸阀的扭矩不容乐观,而且在全关时,阀板经常出现泄漏的现象,对生产造成极大的不便。为此,本技术提供平板钢阀门来解决以上问题。
技术实现思路
针对上述情况,为克服现有技术之缺陷,本技术提供了平板钢阀门,有效的解决了传统的钢板阀门的扭矩过大太大的问题。其解决的技术方案是,包括竖直放置的壳体,壳体左右两侧均固定有水平的平管,平管与壳体腔内连通,平管相互远离的一端固定有与平管同轴的法兰盘;所述的壳体内有能前后转动的蜗轮,蜗轮下端固定有能随蜗轮转动的扇形板,扇形板的左右两端面与壳体的侧壁紧密接触,扇形板上开有与平管同轴且贯穿扇形板左右端面的通孔,壳体内有沿前后方向安装且能主动转动的蜗杆,蜗杆与蜗轮啮合。本技术结构巧妙,有效的减小了开启或者关闭过程中需要的扭矩,尽可能的避免泄露。附图说明图1为本技术主视剖视图。图2为本技术侧视剖视图。具体实施方式以下结合附图对本技术的具体实施方式做出进一步详细说明。由图1至图2给出,本技术包括竖直放置的壳体1,壳体1左右两侧均固定有水平的平管2,平管2与壳体1腔内连通,平管2相互远离的一端固定有与平管2同轴的法兰盘3;所述的壳体1内有能前后转动的蜗轮4,蜗轮4下端固定有能随蜗轮4转动的扇形板5,扇形板5的左右两端面与壳体1的侧壁紧密接触,扇形板5上开有与平管2同轴且贯穿扇形板5左右端面的通孔,壳体1内有沿前后方向安装 ...
