The invention provides a non-power quantitative unloading valve, the unloading valve is provided with an inlet on the upper side of the circular valve body and an outlet on the lower side; four hollow curved arc baffles are evenly distributed on the middle rotating shaft, a counterweight cylinder rotated with the rotating shaft is installed on the outer end of the rotating shaft, and four hollow curved arc baffles are installed inside and counterweight. The barrel is equipped with a counterweight body; the inside and the upper part of the inlet are equipped with an inclined baffle block, the lower side of which is equipped with an anti-blocking scraper which can slide up and down, and the movable setting; two of the four hollow curved arc baffles corresponding to the outer side of the empty baffle are closed plates, thus forming an integral baffle which can automatically unload two empty baffles and seal two empty baffles. Impeller structure. The invention can be installed on the granular material conveying pipe, and when the granular material enters the material bin from the inlet, it deflects under the action of gravity, so as to continuously and quantitatively convey the material without power.

无动力可定量卸料阀
本专利技术涉及一种物料输送管道中安装使用的阀门,具体的说是一种无动力可定量卸料阀。
技术介绍
在很多颗粒料加工企业,会在颗粒输送管中间安装使用卸料阀,目的是通过内置的转动挡料板防止输送管道内回升气流带动颗粒料回转,传统的卸料阀是在转轴上分布数个直板的挡板,阀体的进料口和出料口均设在中间,通过动力带动转轴旋转,从而达到卸料的目的,这种传统的卸料阀在使用中完全依靠动力作业,造成能源消耗并直接影响生产成本。
技术实现思路
本专利技术的目的在于解决上述存在的动力消耗问题,提供一种无动力可定量卸料阀。本专利技术包括卸料阀的阀体和进料口及出料口,所采用的技术方案在于:所述卸料阀在圆形阀体的上方一侧设有进料口,下方另一侧设有出料口;中间的转轴上均匀分布四个空芯弯弧挡料板,转轴外端安装有随转轴旋转的配重筒,四个空芯弯弧挡料板内和配重筒内均装有配重体;在进料口内的内侧上方设有倾斜挡料块,其下侧装有可上下滑动、活动设置的防堵刮板;四个空芯弯弧挡板其中两个对应的空挡外侧为封闭板,由此构成整体挡板可两个空挡自动卸料两个空挡封堵的自动旋转叶轮结构。上述技术方案中:在转轴的另 ...
