Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of valves and relates to a turbine type center line butterfly valve. Background Art
[0002] The existing turbine centerline butterfly valve, if used in a deep well, will have its body immersed in water during use, and external water will enter the turbine box through the gap between the valve body and the turbine box, damaging the turbine box and reducing the service life of the turbine box. Utility Model Content
[0003] The utility model aims to provide a turbine type center line butterfly valve, which has a simple structure, novel and reasonable design, and can effectively prevent external water from entering the turbine box through the gap between the valve body and the turbine box, damaging the turbine box and reducing the service life of the turbine box.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a groove is provided at the top flange of the valve body, and an O-ring is installed in the groove at the top flange of the valve body. The valve body and the turbine box are sealed by the O-ring to prevent external water from entering the turbine box through the gap between the valve body and the turbine box, damaging the turbine box and reducing the service life of the turbine box.
[0005] Preferably, the O-ring (2) is made of NBR70 material.
[0006] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and requires little modification compared with the traditional turbine type centerline butterfly valve, and can effectively prevent external water from entering the turbine box through the gap between the valve body and the turbine box, thereby damaging the turbine box and reducing the service life of the turbine box through simple modification.
