Abstract
The utility model discloses a pneumatic wear-resistant adjusting butterfly valve, which comprises a valve body (1). A valve plate (2) is equipped inside the valve body (1). The valve plate (2) is connected with a valve stem (3). The upper end of the valve stem (3) is further connected with a pneumatic piston type actuator (4). Cemented carbides are welded on the inner chamber of the valve body (1) and the surface of the valve plate (2) in a surfacing way. By making the cemented carbides welded on the inner chamber of the valve body and the surface of the valve plate in a surfacing way, the pneumatic wear-resistant adjusting butterfly valve in the utility model is enabled to have the advantages of relatively strong flushing resistance, excellent wear-resistant performances and long service lifetime.
Description
Technical field
The utility model relates to a kind of adjusting butterfly valve, particularly a kind of pneumatic wear-resisting adjusting butterfly valve.
Background technique
The wear-resisting property of existing its valve body of adjusting butterfly valve and valve plate is poor, causes its working life short, many defectives such as inconvenient operation.
Summary of the invention
To the shortcoming that tradition is regulated butterfly valve, the utility model provides a kind of novel pneumatic wear-resisting adjusting butterfly valve.
To achieve these goals, the measure taked of the utility model:
Pneumatic wear-resisting adjusting butterfly valve comprises valve body, is provided with valve plate in the said valve body, and said valve plate is connected with valve rod, and the upper end of said valve rod also is connected with Pneumatic piston actuator; The inner chamber of said valve body and the surface overlaying of valve plate have cemented carbide;
Said Pneumatic piston actuator is made up of electropneumatic valve positioner, air-filtering reduction valve, valve conveyer and handwheel.
The beneficial effect of the utility model: the inner chamber of the utility model valve body and the surface overlaying of valve plate have cemented carbide, thus the utlity model has stronger anti-ly wash away, wear-resisting property, long service life.
Description of drawings
Fig. 1, the structural representation of the utility model.
Embodiment
Pneumatic wear-resisting adjusting butterfly valve comprises valve body 1, is provided with valve plate 2 in the said valve body 1, and said valve plate 2 is connected with valve rod 3, and the upper end of said valve rod 3 also is connected with Pneumatic piston actuator 4; The surface overlaying of the inner chamber of said valve body 1 and valve plate 2 has cemented carbide; Said Pneumatic piston actuator 4 is made up of electropneumatic valve positioner, air-filtering reduction valve, valve conveyer and handwheel.
The beneficial effect of the utility model: the inner chamber of the utility model valve body and the surface overlaying of valve plate have cemented carbide, thus the utlity model has stronger anti-ly wash away, wear-resisting property, long service life.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in related domain.
