Embodiment

As shown in Figure 1, the utility model is a kind of swing switching valve, and it mainly is made up of body 1, valve body 2, rocking bar 3, end cap 4, rotating shaft 5, bearing pin 6, switching driving lever 7, return spring 8, driving lever spring 9, Packing spring 10, ball sealer 20, flowing water cover 30.

Described valve body 2 is a hollow pipe fitting, has a holding cavity, and this valve body 2 is nested with in body 1.Described flowing water cover 30 is installed in valve body 2 lower end mouth, is provided with a water intake 301 and two water outlets 302 (as shown in Figure 5) on flowing water cover 30.

As shown in Figure 2, described body 1 has a holding cavity that can allow valve body 2 be inserted in, and its profile can be the cylindrical body in the present embodiment, also can be other shape.Body 1 also offer with flowing water cover 30 on water intake 301 and the corresponding water intake 11 of two water outlets 302 (as shown in Figure 5) and two water outlets 12.

As shown in Figure 1, described return spring 8 is a pressure spring, is nested with at valve body 2 holding cavities, and its two ends lean respectively on the ladder surface of the lower end surface of rocking bar 3 and valve body 2 holding cavity inwalls.

Shown in Figure 1 as Fig. 3 A, Fig. 3 B reference, described rocking bar 3 low profile are spherical surface body, what the bottom of rocking bar 3 can be swung is nested with in valve body 2 holding cavities, its end cap 4 sphere inside groove interior with being installed in valve body 2 upper end-hole cooperates, offer a counterbore 31 in the bottom of rocking bar 3, rotating shaft 5 laterally is set in this counterbore 31.
