The ball valve is a common pipeline valve, an internal ball body is driven by a valve rod and rotates around the axis of the ball valve, the ball valve can be used for adjusting and controlling fluid, the converging, the diverging and the flow direction switching of media can be flexibly controlled on a pipeline, meanwhile, any channel can be closed to enable the other two channels to be connected, and the boiler ball valve is a valve used in a boiler system and used for controlling the flow rate and opening and closing of the fluid.

When the traditional boiler ball valve is in actual use, in order to prevent impurities in fluid from entering a terminal, a filtering device is generally required to be additionally installed. Patent document No. CN201620719878.5, entitled "ball valve", discloses a ball valve with a filtering device, which provides a filtering member at the inlet end of a valve seat, and a slag discharge hole at the front of the filtering member, and discharges impurities left by the filtering member by the impact force of fluid by opening the slag discharge hole. However, the filtering device needs to open the valve at the same time during slag discharging, which not only results in waste due to loss of a part of fluid, but also results in instant reduction of the fluid pressure of the fluid system due to the fact that the part of the fluid is flushed out from the slag discharging hole, and if the valve is closed, impurities cannot be flushed out, so that the filtering device cannot be used in a scene with a high requirement on hydraulic stability.

Therefore, there is a need for a boiler ball valve with a filtering device that can be easily installed, removed and taken out of impurities.
