Abstract
A butterfly valve with a valve disk mounted to swivel about an axis of rotation inside a housing and torsionally rigidly connected to a drive shaft pivotably mounted inside the housing. To ensure a connection which, from the standpoint of production engineering, is simple, yet secure, the valve disk is torsionally rigidly connected to the drive shaft by means of a minimum of two tapered pins engaging opposite sides of the drive shaft.
Claims10
A butterfly valve comprising:
- a housing;
- a valve disk swivel-mounted about an axis of rotation inside the housing;
- the valve disk including a valve body having a disk shape and two hubs disposed opposite to each other and each projecting beyond a front side of the valve body;
- a drive shaft mounted inside the housing;
- a bearing bolt disposed in the one of the two hubs opposite mounting of the drive shaft;
- a lateral opening in each of the two hubs, a first of the lateral openings for receiving the drive shaft and a second of the lateral openings, opposite the first, for receiving the bearing bolt;
- at least two tapered pins configured for engaging opposite sides of the drive shaft, the at least two tapered pins torsionally, rigidly connecting the valve disk to the drive shaft;
- bores for receiving the at least two tapered pins, the bores extending tangentially through a hub of the two hubs with respect to the lateral opening;
- and
- a retaining ring attached to the valve body with screws, the retaining ring covering the bores;
- wherein the at least two tapered pins connect the valve disk and the drive shaft.
