一. use:

1. This valve is mainly applicable to the vacuum pipeline of direct fired lithium bromide refrigeration units.

2. This valve can also be used in other types of pipelines to transport other media suitable for this valve, such as water, oil, gas, or other corrosive media.

二. Performance characteristics:

1. This valve breaks through the traditional ball valve design by using patented technology to combine a spherical structure. The sphere is divided into a wedge and two lobes, and is equipped with a novel driving device, as shown in the diagram. When the valve is opened, the wedge rises and the lobes on both sides contract towards the center. It can open a large diameter valve with a small torque, making it easy to feel and the seal is less stressed, making it less prone to deformation. When the valve is closed, the ball wedge moves downwards, pushing the ball disc open to both sides, thereby achieving excellent sealing performance.

2. This valve is equipped with a locking device to ensure stable performance after opening and closing.

3. This valve has added a secondary sealing structure to make the sealing more secure and reliable.

4. The valve and vacuum unit are connected by welding, which has better sealing performance than other forms of connection.
