Preferably, the material of the blade is one of stainless steel, plastic or alloy. Aiming at some common fiber-carrying media, stainless steel or plastic blades with low price can be selected; for some alloy blades with solid particles or corrosive media, high-strength and corrosion-resistant alloy blades can be selected. The blades made of different materials are adopted for different media, so that the shearing capability of the V-shaped ball valve is improved in a more targeted manner, and more selectivity is brought to customers.

Preferably, the valve seat is provided with an O-ring and a spring. Set up O type circle and can prevent that the medium from revealing and the medium backward flow, set up the spring and can guarantee that V type ball has certain elasticity and elasticity between with the disk seat when shearing solid impurity and some other difficult shearing impurity, when guaranteeing sealed, prevents to damage V type ball and disk seat.

Compared with the prior art, this reinforcing shearing force V type ball valve has following advantage:

1. the blade is fixed in the V-shaped ball, the shearing capacity of the V-shaped ball valve is enhanced, medium impurities and fibers can be effectively prevented from being clamped, and inconvenience caused by maintenance is reduced.

2. Aiming at different forms and different types of media, the material of the blade can be replaced by one of stainless steel, plastic or alloy, and the blade has the advantages of strong pertinence and convenience in installation.
