Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Such as Fig. 1, shown in Figure 2, a kind of selector valve described in the utility model improves structure, comprises the valve body that is formed by upper valve body 4 and 14 docking of lower valve body, laterally is provided with valve pocket 8 in the described valve body, and described valve pocket 8 two ends are respectively by left valve barrel 1 and right valve barrel 10 sealings.
Described upper valve body 4 is provided with import 9, and described lower valve body 14 is provided with outlet A13 and outlet B17, described import 9, and outlet A13 and outlet B17 are communicated with valve pocket 8 respectively, and the described left valve barrel 1 interior through hole 2 that laterally is provided with is provided with receiving bore 11 in the described right valve barrel 10.Described left valve barrel 1 is provided with pressurising mouth A21, and pressurising mouth A21 is communicated with through hole 2, and described right valve barrel 10 is provided with pressurising mouth B22, and pressurising mouth B22 is communicated with receiving bore 11.
Be provided with valve rod assembly in the described valve pocket 8, the valve rod assembly two ends are located at respectively in through hole 2 and the receiving bore 11.Particularly, described valve rod assembly comprises left valve rod 23, right valve rod 12, and stretch out outside the through hole 2 described left valve rod 23 outer ends, and described right valve rod 12 outer ends place in the receiving bore 11.
Be fixed with spool between described left valve rod 23 and the right valve rod 12, the preferred described spool of the utility model is arranged with valve core housing 7 outward, spool is formed effectively fixing.Described spool comprises upper valve core sheet 6, lower valve core sheet 16 and be located at upper valve core sheet 6 and lower valve core sheet 16 between Compress Spring 3, the described upper valve core sheet 6 hole A5 of the company of being provided with, correspondence is provided with and connects hole B15 on the described lower valve core sheet 16.The described hole A5 of company and the hole B15 of company form the fluid passage jointly.
