Double density structure of an electric valve, density structure of an electric valve, and electric valve of static density structure

摘要

A double density structure of an electric valve, a density structure of an electric valve, and an electric valve of static density structure are revealed;and the double-density structure of an electric valve includes a valve body (1) and a valve insert (2),where the valve body (1) is partly formed by injection moulding, between the valve body (1) and the valve application (2) a first seal (4) and a second seal (5) are arranged, which are configured to prevent the leakage of a cooling fluid into an upper assembly space for a drive device,where the first seal (4) and the second seal (5) are arranged along an axial direction of the valve application (2) above each other.
