The purpose of this utility model provides switch valve with two-position and five-pass, and it has the function of multi-path commutation, and it is large also to have a flow, can satisfy the advantage of large flow control demand.
To achieve these goals, the technical solution adopted in the utility model is as follows: switch valve with two-position and five-pass, comprise valve body and be positioned at the valve rod of valve body, have five ports on the described valve body, have two annular breach on the described valve rod and be implemented in the different paths of composition under the valve rod different station from above-mentioned five ports cooperation, one end of described valve rod has makes valve rod recover the Returnning spring of initial position, the other end of valve rod is the calutron that makes the valve rod transposition, it is characterized in that, be fixedly provided with the annular spacer that is nested with on valve rod in the valve pocket of described valve body, described valve rod can move relative to spacer, and the position corresponding to five ports on the described spacer offers five through holes.
Preferably, an end end face that joins with calutron on the described valve rod has piston.
Preferably, the surface of contact between described piston and the valve body is provided with piston packing.
Preferably, described valve body has bonnet, and described Returnning spring is between valve rod and bonnet.
Preferably, described valve rod has blind hole, and described bonnet inner side surface has restraining groove, and the two ends of described Returnning spring lay respectively in described blind hole and the restraining groove.
Compared with prior art, switch valve with two-position and five-pass of the present utility model, by between valve body and valve rod, adding spacer, valve rod can move relative to spacer, and the position corresponding to five ports on the spacer offers five through holes, make five ports form different connecting passages according to the Switch of working position of valve rod with this, realize the function of multi-way reversing, and because the through hole on the spacer is larger than space, existing switch valve with two-position and five-pass inner passage, can hold more fluid in unit time, therefore possess the existing larger advantage of switch valve with two-position and five-pass of flow-rate ratio, can satisfy the demand of large flow control.

Embodiment
Below in conjunction with accompanying drawing and embodiment the technical solution of the utility model is described.
As shown in Figure 1, the utility model is a kind of switch valve with two-position and five-pass, comprise valve body 10 and be positioned at the valve rod 20 of valve body 10, have five ports on the described valve body 10, have two annular breach 21 on the described valve rod 20 and be implemented in the different paths of composition under valve rod 20 different stations from above-mentioned five ports cooperation, one end of described valve rod 20 has makes valve rod 20 recover the Returnning spring 30 of initial position, the other end of valve rod 20 is the calutron 40 that makes valve rod 20 transpositions, it is characterized in that, be fixedly provided with the annular spacer 50 that is nested with on valve rod 20 in the valve pocket of described valve body 10, described valve rod 20 can move relative to spacer 50, and the position corresponding to five ports on the described spacer 50 offers five through holes 51.Compared with prior art, switch valve with two-position and five-pass of the present utility model, by between valve body 10 and valve rod 20, adding spacer 50, valve rod 20 can move relative to spacer 50, and the position corresponding to five ports on the spacer 50 offers five through holes 51, make five ports form different connecting passages according to the Switch of working position of valve rod 20 with this, realize the function of multi-way reversing, and because the through hole 51 on the spacer 50 is larger than space, existing switch valve with two-position and five-pass inner passage, can hold more fluid in unit time, therefore possess the existing larger advantage of switch valve with two-position and five-pass of flow-rate ratio, can satisfy the demand of large flow control.
