Installing space, expands the range of hydraulic multitandem valve.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: a kind of hydraulic multitandem valve is provided,
The overflow valve including valve body, being arranged on valve body and the spring cavity in valve body and valve element, described valve body is provided with and overflow
Guide's oil-in of valve connection, described valve body is provided with winding type end cap, and described winding type end cap is connected formation ring with overflow valve
Shape oil duct, the hydraulic oil that described guide's oil-in enters enters spring cavity by ring shaped oil passage makes spring cavity promote valve element.
In one preferred embodiment of this utility model, in described valve body, it is additionally provided with guide's oil passage, described guide oil
Liquid channel connection is between spring cavity and ring shaped oil passage.
In one preferred embodiment of this utility model, described winding type end cap is set in the outside of spring cavity.
In one preferred embodiment of this utility model, the left and right sides of described valve body is arranged with guide's oil-in, overflows
Stream valve, winding type end cap and spring cavity.
In one preferred embodiment of this utility model, described spring intracavity is provided with and is connected for promoting valve element with valve element
Spring.
The beneficial effects of the utility model are: this utility model hydraulic multitandem valve, can reduce the installation of hydraulic multitandem valve
Space, expands the range of hydraulic multitandem valve.

Formula end cap 6, winding type end cap 6 is connected formation ring shaped oil passage 8 with overflow valve 2, and the hydraulic oil that guide's oil-in 5 enters passes through annular
Oil duct 8 enters spring cavity 3 makes spring cavity 3 promote valve element 4.
In addition, being additionally provided with guide's oil passage 9 in valve body 1, guide's oil passage 9 connects in spring cavity 3 and ring shaped oil passage 8
Between.Winding type end cap 6 is set in the outside of spring cavity 3.
In addition, the left and right sides of valve body 1 is arranged with guide's oil-in 5, overflow valve 2, winding type end cap 6 and spring cavity 3.
It is provided with the spring 7 being connected for promoting valve element 4 with valve element 4 in spring cavity 3.
This utility model hydraulic multitandem valve concrete operating principle is as follows: guide oil is entered by guide's oil-in 5, through circuitous
Returning the ring shaped oil passage 8 of formula end cap 6 and overflow valve 2, spring cavity 3 being entered by guide's oil passage 9, thus promoting the fortune of valve element 4
Dynamic, flow area:.
It is different from prior art, this utility model hydraulic multitandem valve, the installing space of hydraulic multitandem valve can be reduced, expand
The range of hydraulic multitandem valve.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description or equivalent flow conversion, or directly or indirectly it is used in other phases
The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
