Abstract

The utility model discloses a pneumatic wear-resistant adjusting butterfly valve, which comprises a valve body (1), wherein a valve plate (2) is arranged in the valve body (1), the valve plate (2) is connected with a valve rod (3), and the upper end of the valve rod (3) is also connected with a pneumatic piston type actuating mechanism (4); hard alloy is welded on the inner cavity of the valve body (1) and the surface of the valve plate (2) in a stacking mode. The utility model has the advantages that: the utility model discloses the inner chamber of valve body and the surface surfacing of valve plate have the carbide, so the utility model discloses have stronger resistant scouring, wear resistance, long service life.

Description

Pneumatic wear-resisting adjusting butterfly valve

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.
