Abstract
The utility model discloses a kind of agricultural vehicle hydrovalve, comprise valve seat and valve pocket, valve pocket is plugged in valve seat end by the valve pocket mating cavity of end, valve pocket mating cavity mouth inner wall is provided with jam groove, valve seat end outer wall is provided with bulge loop, bulge loop external diameter is greater than valve pocket mating cavity internal diameter, and valve seat and valve pocket crimp and to be connected and bulge loop snaps in jam groove.The utility model decreases Product processing operation, has stopped the jam phenomenon of valve pocket and valve base chamber.
Description
Technical field
The utility model relates to hydraulic transmission technology field, is especially a kind ofly used for as the hydraulic element such as oil cylinder play the hydraulic valve of pilot pressure, direction, flow etc.
Background technique
As shown in Figure 1, the cartridge valve of current domestic production and use, linkage structure between valve seat 2 and valve pocket 1 is, jam groove 5 is provided with at valve pocket mating cavity 4 mouth inner wall, simultaneously be provided with annular groove 6 and snap ring 7 at valve seat outer wall, limit structure be adopt snap ring and jam slot fit to realize.Current structure is when finished product is assembled, and assembling speed is slow, process links is many, efficiency is low, makes valve pocket action sensitive not, can not accurately put in place during work, easily occurs the phenomenon that snap ring is deviate from.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of agricultural vehicle hydrovalve, improves assembling speed, improving production efficiency, reduces process links, Improving The Quality of Products, reduces cost of production.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of agricultural vehicle hydrovalve, comprise valve seat and valve pocket, valve pocket is plugged in valve seat end by the valve pocket mating cavity of end, valve pocket mating cavity mouth inner wall is provided with jam groove, valve seat end outer wall is provided with bulge loop, and bulge loop external diameter is greater than valve pocket mating cavity internal diameter, and valve seat and valve pocket crimp and to be connected and bulge loop snaps in jam groove.
Preferably, valve seat end outer wall is provided with seal groove on front side of bulge loop, is provided with seal ring in seal groove.
Preferably, the diameter of valve seat end on rear side of bulge loop is less than the diameter on front side of bulge loop.
Preferably, be arc transition structure between the front end of bulge loop and rear end.
The utility model improves on valve seat, and original snap ring is improved to a bulge loop; The connection of valve seat and valve pocket realizes connecting by adopting the mode be pressed into, and the bulge loop connected on rear valve base realizes coordinating with the jam groove of valve pocket inner chamber; Its beneficial effect brought is:
1, Product processing operation is reduced;
2, the jam phenomenon of valve pocket and valve base chamber has been stopped;
3, manufacturing efficiency 50% to 80% is improved;
4, cost of production reduces by more than 10%.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is valve pocket and valve seat connecting structure schematic diagram in prior art;
Fig. 2 is valve pocket and valve seat connecting structure schematic diagram in the utility model;
Fig. 3 is valve seat construction schematic diagram;
Fig. 4 is valve seat partial structurtes schematic diagram;
Fig. 5 is housing configuration schematic diagram;
Fig. 6 is valve pocket partial structurtes schematic diagram.
Embodiment
As shown in Figures 2 to 6, a kind of agricultural vehicle hydrovalve, comprise valve seat 2 and valve pocket 1, valve pocket is plugged in valve seat end by the valve pocket mating cavity 4 of end, valve pocket mating cavity mouth inner wall is provided with jam groove 5, valve seat end outer wall is provided with bulge loop 3, and bulge loop external diameter is greater than valve pocket mating cavity internal diameter, and valve seat and valve pocket crimp and to be connected and bulge loop snaps in jam groove.Valve seat end outer wall is provided with seal groove 8 on front side of bulge loop, is provided with seal ring 9 in seal groove.The diameter 10 of valve seat end on rear side of bulge loop is less than the diameter 11 on front side of bulge loop.It is arc transition structure between the front end of bulge loop 3 and rear end.
The object that in the utility model, bulge loop 3 designs is the snap ring 7 used in alternative prior art, valve pocket mating cavity 4 interference fit in the external diameter of bulge loop 3 and valve pocket 1, jam groove 5 is the running position chamber of bulge loop 3, by after the bulge loop 3 above valve seat 2 and valve pocket mating cavity 4 force fit in valve pocket 1, valve seat 2 can unrestricted motion in valve pocket mating cavity 4, finally reaches raising assembling speed, carry out improving production efficiency, reduce process links, Improving The Quality of Products, reduce the object of cost of production.
