Description

Anti-blocking three-way fixed ball valve Technical Field The utility model relates to the technical field of three-way ball valves, in particular to an anti-blocking three-way fixed ball valve. Background The three-way ball valve is a valve capable of controlling medium flow among three pipelines, and can realize the functions of diversion, confluence, reversing or cutting off of the medium through the rotary sphere, and is widely applied to industries such as petroleum, chemical industry, metallurgy, electric power, water treatment and the like. When carrying out liquid through the tee bend ball valve, be provided with the impurity in liquid, when the impurity in the liquid enters into in the spheroid, there is the condition of piling up in the valve pocket to take place, leads to showing to reduce medium circulation efficiency, causes system pressure anomaly or flow fluctuation, influences process flow stability, and the jamming can lead to the unable normal switching flow direction of valve or close completely between spheroid and the disk seat, influences system control precision, needs to clear up regularly, but the process of dismantling is comparatively loaded down with trivial details, so we propose a prevent blockking up tee bend fixed ball valve. Disclosure of utility model The utility model aims to provide an anti-blocking three-way fixed ball valve so as to solve the problems in the prior art. Prevent blockking up tee bend fixed ball valve, including the spheroid, the spheroid is rotated and is connected with the disk seat, be provided with the inlet on the spheroid, inlet department is provided with filter unit, filter unit is used for filtering liquid, be provided with the discharge unit on the spheroidal outer wall, the discharge unit is used for discharging impurity, filter unit is linked together with the discharge unit, filter unit includes: the filtering frame is positioned in the liquid inlet and is used for filtering liquid; The guide frame is arranged on the front surface of the filter frame and is used for guiding liquid; The mounting seat is fixedly connected in the liquid inlet, and the filter frame and the guide frame are fixed with the filter frame and the guide frame through bolts.
