The utility model discloses a parallel synchronous double disc gate valve for powder medium and high and low temperature fluid passage, which comprises a valve body and a cover separated on both sides of the valve body. The valve cover and the valve body form a valve cavity, and an inlet and outlet are arranged on the valve cover to form a fluid passage. The valve body is equipped with a valve stem, which extends downward through the valve cavity and connects with a disc support. The valve disc can slide up and down the side wall of the valve chamber to open and close the gate valve. A compression spring is installed between the two discs to make the disc and the side wall of the valve chamber close together. A groove is arranged on one side of the compression spring of the two discs, which is used for installing in the groove. Synchronization plate to synchronize the action of two valve discs. The beneficial effect of the utility model is that the motion of the valve disc is more stable and synchronous through the synchronous plate, the wear of the valve disc is more uniform, and the service life is long.

一种平行同步双阀盘闸阀
本技术涉及阀门
,尤其涉及一种平行同步双阀盘闸阀。
技术介绍
闸阀,主要用于介质为粉体、高低温流体通路上作阀门用,广泛应用于电力、化工等行业。现有公知技术的平行双阀盘闸阀其基本结构由阀体、二只阀盖构成阀腔,阀盖上设有阀门进出口;两块阀盘独立安装于阀杆末端,用弹簧涨紧,可独立运动,并与两侧阀腔两侧壁紧密贴合;阀盘由阀杆带动阀座紧贴密封面作直线滑动,从而打开或关闭阀门。由于两块阀盘各自独立安装,自由度较大,两块闸板运动状态不一致,将导致两侧阀盘和阀盖磨损情况不一样,不均匀磨损将缩短阀门使用寿命。
技术实现思路
有鉴于此,本技术的目的是提供一种平行同步双阀盘闸阀,从而解决了现有平行双阀盘闸阀的阀盘动作不同步、阀盘磨损不均匀的问题。本技术通过以下技术手段解决上述技术问题:一种平行同步双阀盘闸阀,包括阀体,分居于阀体两侧的阀盖,所述阀盖与阀体形成阀腔,在所述阀盖上设有进出口并形成流体通道;在所述阀体上安装有阀杆,所述阀杆向下延伸并穿过阀腔与一阀盘支座连接,在所述阀盘支座两端各安装有一阀盘,在阀杆的带动下,所述阀盘可沿阀腔的侧壁上下滑动从而开启和关闭闸阀 ...
