Abstract

The invention discloses a diversion valve which comprises a valve body (3); the valve body (3) is provided with a three-way inner cavity comprising an upper inner cavity, a left inner cavity and a right inner cavity; a turnover plate (1) positioned between the left inner cavity and the right inner cavity and positioned under the upper inner cavity is arranged in the inner cavity, the lower end of the turnover plate (1) is hinged to the bottom wall of the valve body (3) through a turnover plate shaft (2), and a ferrule I (4) and a ferrule II (5) are respectively arranged on the two sides of the upper end of the turnover plate (1); a hole I (7) and a hole II (8) for allowing a glass rope to thread through are respectively formed in the two sides of the valve body (3); the ferrule I (4) is connected with the glass rope in the hole I (7); the ferrule II (5) is connected with the glass rope in the hole II (8); the upper inner cavity is connected with an inlet; the inlet is connected with a filtering pipe and a connecting port of which the internal diameter is larger than the external diameter of the filtering pipe. The diversion valve disclosed by the invention is simple in structure, convenient to operate and low in cost and has a filtering function, and the valve body is not easy to damage.

Description

technical field [0001] The invention relates to a valve, in particular to a diversion valve. Background technique [0002] In many industrial situations, it is necessary to use diverter valves to introduce water flow into different pipes. [0003] Most of the existing diversion valves are electrically controlled. However, in some occasions where diversion switching is infrequent and cost-sensitive, the existing diversion valve cannot meet the requirements due to the defects of cumbersome operation and high cost, and it does not have a filtering function, and the inside of the valve body is easily corroded and damaged. Low service life. Contents of the invention [0004] The purpose of the present invention is to provide a diversion valve with simple structure, good operability, low cost and long service life. [0005] Technical scheme of the present invention is as follows: [0006] A diversion valve has a valve body, the valve body has a three-way inner cavity includi...
