A multi-cone spool valve assembly

The utility model relates to a multi-cone-core valve assembly. Wherein the valve seat (1) and the valve body (3) are hermetically connected from bottom to top; a plurality of valve seat circulation holes (10) are formed in the valve seat (1), conical cores (2) are arranged in the valve seat circulation holes (10), a plurality of valve body circulation holes (11) are formed in the valve body (3), and balance weight columns (6) are arranged at the positions, corresponding to the valve seat circulation holes (10), in the valve body circulation holes (11). Compared with the prior art, the utilitymodel has the advantages that the service life is ultra-long, the maintenance frequency is reduced, meanwhile, all the conical cores and the balance weight columns have interchangeability, the valve seat, the valve body, the pressing plate and the limiting plate have symmetrical double-sided design, the reusability is very high, and the functional problem caused by wrong installation is avoided. 本实用新型涉及一种多锥芯阀组件，包括自下而上密封连接
