Problems solved by technology
[0002] Ball valve is a common type of valve, which can be opened and closed by twisting the valve. The existing ball valve cannot filter the internal medium, and often choose to install a filter screen when filtering, which can only meet certain requirements. Fixed filtration degree, if the filter mesh number needs to be replaced, the practicability is poor

The invention discloses a sealing ball valve with a multi-filtering function, which comprises a valve body, and is characterized in that a handle is arranged at the top of the valve body, a multi-filtering device is arranged in the valve body, the multi-filtering device comprises a middle shell, a two-way suction water pump is embedded in the middle shell, and the two-way suction water pump is arranged in the middle shell. The input end and the output end of the two-way suction water pump are correspondingly connected with a first reversing valve and a second reversing valve in a penetrating mode, the two ports of the first reversing valve are connected with an upper filtering bag and a left filtering bag in a penetrating mode respectively, and the two ports of the reversing valve are connected with a right filtering bag and a lower filtering bag in a penetrating mode respectively. One end of each of the upper filter bag, the left filter bag, the right filter bag and the lower filter bag is provided with an on-off valve, the on-off valves are electrically connected with the two-way suction water pump through an external control system, the first reversing valve and the second reversing valve are electrically connected with the external control system, and the device solves the problem of poor practicability at present.
Description
technical field [0001] The invention belongs to the technical field of valves, in particular to a sealed ball valve with multiple filtering functions. Background technique [0002] The ball valve is a common type of valve, which can be opened and closed by twisting the valve. The existing ball valve cannot filter the internal medium, and a filter screen is often selected for filtering, which can only meet certain requirements. With a fixed degree of filtration, if the filter mesh number needs to be replaced, the practicability is poor. This phenomenon has become an urgent problem to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a sealed ball valve with multiple filtering functions for the existing material skid device, so as to solve the problems raised in the above-mentioned background art. [0004] In order to solve the above technical problems, the present invention provides the following te...
