Abstract
The utility model discloses a water injection valve casing which comprises a casing body in the shape of a ladder. A communication cavity is arranged in the casing body and comprises a back cavity and a front cavity. A partition plate is arranged between the back cavity and the front cavity, a round hole is arranged on the partition plate, an air inlet hole communicated with the front cavity and a water inlet hole communicated with the back cavity are arranged on the lateral wall of the casing, and connection threads are arranged on the lateral wall of the casing. The water injection valve casing reduces whole weight and is simple in structure and good in sealing performance.
