The utility model relates to a five valve group, which mainly solves the existing sewage valve structure of the five valve group complex, is not conducive to the production and assembly technology; which is characterized in that the drain valve comprises a regulating bolt and a mounting seat, wherein the mounting seat is fixed on the valve body, is provided with a threaded hole the sewage and the screw hole and the valve body connected on the mounting seat, wherein the discharge adjusting bolt passes through the threaded hole arranged in the valve body mounting seat in the mouth and discharge screw hole and the valve body mounting in threaded connection, the installation seat on the side wall of the valve body near the end is provided with a discharge hole the sewage, communicated threaded hole hole and the mounting seat; the utility model has the advantages of using the adjusting bolt to control valve through the sewage outfall closed and through the sewage hole mounting emission, by this way, not only can The utility model optimizes the discharge valve structure of the five valve group, and can realize the blowdown operation conveniently and rapidly. Meanwhile, the utility model can also facilitate the processing, the production and the assembly of the blowdown valve, and the cost is low.
【技术实现步骤摘要】
本技术涉及一种阀门组件,更具体的说是涉及一种仪表用的五阀组,主要应用于安装各类精密仪表仪器。
技术介绍
五阀组是在三阀组的基础上增加两组排污阀而改进而来,而排污阀的主要作用是 排除导压管内或压差变送器内的空气或污物,以保证仪表仪器的测量准确性。现有五阀组 主要包括有安装在阀体上的两组控制阀、一组平衡阀及两组排污阀,所述的两组排污阀相 应安装在阀体内的两组排污口处;为方便排污,所述的阀体外设有两组排污管,该排污管与 阀体内的排污口相通且两组排污阀分别控制阀体内相应的排污口的通闭;采用这种方式, 五阀组在排污时,阀体内的污物无法直接从阀体的排污阀处直接排出,只能通过设在阀体 外的排污管实现排污,这样阀体内的排污结构相对复杂,而排污阀的结构与阀体上的控制 阀结构相似且还需要在阀体上加设排污管,这样不仅增加了五阀组的材料成本,同时,还不 利于五阀组的组装,组装时效益较低,从而提高了五阀组的整体生产成本。
技术实现思路
为了解决现有五阀组的排污阀结构复杂,不利于生产组装等技术问题;本技术提供一种五阀组,该五阀组的排污阀不仅可降低五阀组的材料成本,同时,还可方便排污 阀的组装,提高组装效益。 为解决以上技术问题,本技术采取的技术方案是一种五阀组,其包括有阀体 及安装在阀体上的两组控制阀、一组平衡阀及两组排污阀,所述的两组排污阀安装在阀体 内的排污口处,其特征在于所述的排污阀包括有一调节螺栓及安装座,所述的安装座一端 固定在阀体上,在该安装座内设有一螺纹孔且该螺纹孔与阀体内的排污口相通,所述的调 节螺栓穿过安装座的螺纹孔置于阀体的排污口内并与安装座的螺纹孔及阀体的排污口 ...
