Description

Technical Field

[0001] The utility model relates to the field of back pressure valve processing, and particularly relates to a positioning device for back pressure valve processing. Background Technique

[0002] A back pressure valve is a valve used to control the fluid pressure in a pipeline. By adjusting the spring force or other means, the back pressure valve establishes a relatively stable pressure at the outlet end of the valve, that is, the back pressure. When the outlet pressure is lower than the set back pressure value, the valve closes or partially closes to prevent the fluid from flowing out, thereby increasing the outlet pressure. When the outlet pressure is higher than the back pressure value, the valve opens to allow the fluid to flow out, reducing the outlet pressure to maintain the outlet pressure within the set back pressure range. When processing a back pressure valve, a positioning device is required. Currently, the positioning device for back pressure valve processing has poor stability in limiting the back pressure valve. Therefore, a positioning device for back pressure valve processing is needed.
