Dividing and isolating valve

The utility model discloses a shunting isolating valve, relates to the technical field of valves, and solves the common problems that when one of two paths breaks down and can not be immediately shut down for inspection and maintenance, the maintenance work can be carried out only when a machine is convenient to shut down, and the oil path needs to be isolated. A first input hole channel, a second input hole channel, a first output hole channel and a second output hole channel are formed in the valve body; the sliding channel is formed in the valve body, one end of the sliding channel communicates with the first input hole channel, and the other end communicates with the second input hole channel; and the valve core slides in the sliding channel, so that when one of the two oil ways breaks down, the oil way with the fault can be automatically and timely cut off or isolated under the condition of not immediately stopping for inspection or maintenance, and normal oil supply can be ensured through the other oil
