Description

Technical Field

[0001] The utility model relates to the technical field of a fixed electric cone valve signal device, in particular to a fixed electric cone valve signal device. Background Art

[0002] The electric cone valve is a discharge type fixed cone valve, belonging to the field of mechanical valve industry, especially suitable for water supply and drainage systems and industrial fluid systems. It consists of valve body, gear drive mechanism, sliding sleeve, cone, wing guide rail, etc. The gear drive mechanism drives the sliding sleeve to move forward and backward along the guide rail. As the sliding sleeve moves forward and backward, the flow area between it and the fixed cone changes, thereby controlling the change of flow.

[0003] However, the sliding sleeve gate of a general electric cone valve has no auxiliary guiding and positioning structure during its movement, which may cause the sliding sleeve gate to twist and deviate after long-term use, resulting in a worse valve switch sealing effect and a shortened service life.
