Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing devices, in particular to an ultra-high performance pressure reducing device. Background Art

[0002] Ultra-high performance pressure reducing device is an advanced equipment, mainly used in the industrial field, used to reduce high pressure gas or liquid to the required low pressure state. This device usually consists of multiple components, including pressure reducing valve, regulating valve, control system, etc., to achieve precise pressure control.

[0003] The existing connection methods of pressure reducing valves mainly include threaded connection, flange connection, welding connection, ferrule connection, etc. At the same time, the pressure reducing valve is a device used to reduce pressure. They can be found in different fields and industries. For example, they are used to adjust the pressure in pipelines during industrial production processes.

[0004] However, when the existing pressure reducing valve is connected to the pipeline, the pressure reducing valve is easily suspended in the air, so that when the pressure reducing valve is disassembled, it is easy for the pressure reducing valve to fall, causing the pressure reducing valve to collide with the ground, thereby causing the parts on the pressure reducing valve to scatter. It takes a lot of time to find the parts on the pressure reducing valve, which increases the working time of the staff. Utility Model Content
