一. use:

1. This valve is mainly used in the vacuum pipeline of lithium bromide refrigeration units to connect or cut off the medium in the pipeline, and is generally not used to regulate the flow rate.

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.

3. This valve is not suitable for use in fiber media pipelines.

二. Performance characteristics:

1. This valve has a reasonable design, novel structure, small size, and easy operation.

2. The valve body of this valve is made of stainless steel series bar material directly processed or forged, with high density, eliminating the leakage hazard of the valve body.

3. This valve adopts a patented sealing structure, and the valve seat sealing surface is a metal hard seal. The sealing surface is not easily worn or scratched, with good sealing performance and long service life. Avoiding penetrating leakage of rubber diaphragm sheets in diaphragm valves under high vacuum conditions.

4. The valve stem structure of this valve is unique, effectively separating circular motion and linear motion in the transmission pair, protecting the soft sealing elements on the valve stem, ensuring reliable sealing, and easy maintenance and replacement.

5. The connection between this valve and the vacuum unit adopts plug-in welding, which not only ensures accurate and reliable positioning, but also keeps the pipeline free from pollution such as welding slag.

6. This valve has a small opening and closing torque, short stroke, and large flow rate.
