High-pressure filtering station

A high-pressure filtering station solves the problems that replacement of a filter element or maintenance of a control valve is difficult under a main body in a filter cartridge or the control valve of a traditional high-pressure filtering station and that high-pressure liquid is fully filled with a combined surface and jets outwards if the sealing between the control valve and the main body is failed. The high-pressure filtering station is characterized in that the filter cartridge is arranged above the main body; the control valve is arranged on the lateral surface of the main body; a liquid inlet trench though hole, a liquid outlet trench through hole, a sewage discharging trench through hole, an annular unloading groove and a linear unloading groove are formed in a valve body of the control valve by processing; a liquid inlet hole, a liquid outlet hole, a sewage discharging hole, a control valve liquid inlet trench through hole, a control valve liquid outlet trench through hole and a control valve sewage discharging trench through hole are formed in the main body by processing; and spare parts arranged in the valve body of the control valve can temporarily form an integrally-inserted valve core. The high-pressure filtering station has the beneficial effects that the replacement of the filter element or the maintenance of the control valve is easily realized; the phenomenon that a large amount of liquid is sprayed due to the fact that a sealing element is damaged is avoided; the liquid passes through a large channel; the flowing resistance of fluid is reduced; and the problem that the liquid in a main liquid supply pipeline flows outwards due to the fact that a work surface stops pumping is solved.
