背景技术Background technique
目前橡胶瓣止回阀防止管道水流逆流常用的阀门，但由于橡胶瓣本身材质问题，多才橡胶瓣内部添加钢骨，但橡胶本身材质较重，加上钢骨使橡胶瓣止回阀的开启较为困难，同时受温度影响橡胶瓣发生变化，这种情况如果水压不稳，就会导致密封失效，而且由于橡胶瓣的设计在阀体内具有一定角度，因此阀体底端易受水流冲击导致橡胶瓣位移，导致密封失效。At present, the rubber flap check valve is commonly used to prevent the reverse flow of water in the pipeline. However, due to the material problem of the rubber flap itself, steel bones are often added inside the rubber flap. Difficult, at the same time, the rubber flap changes due to temperature. In this case, if the water pressure is unstable, it will cause the seal to fail, and because the design of the rubber flap has a certain angle in the valve body, the bottom of the valve body is vulnerable to the impact of water flow and the rubber Displacement of the flap, causing the seal to fail.
