Now cryogenic pipeline is carrier of the city goods delivery, and some of them need to use a variety of auxiliary equipment, now the pipeline valve category, which is used to the cold of the pipeline valve, generally the cryogenic valve, this butterfly valve is used in the low temperature pipes, have lower friction, which is to provide assistance for the internal medium conveying. Here is an introduction to the use of this low temperature valve will appear when the problem.

Install at room temperature and work at low temperature, with a wide range of temperature variation. If the design, installation is not appropriate, it is easy to produce thermal stress or deformation. At the same time, the operation part of the valve is at room temperature, the flow part is at low temperature, so often the valve is suddenly stuck in a low temperature environment and does not operate. In order to reduce cold damage, the stem is often made very long, which is easy to produce deformation and stuck. What are the main reasons for the clamping of this low temperature valve? Mainly includes in the installation, the valve and pipeline configuration is not reasonable and prestressed; Or pipeline cold compensation capacity is poor, low temperature valve position change; Or valve lack of support, deformation at low temperature; Or the valve is fixed improperly, the deformation of the cold box at low temperature affects the concentricity of the valve stem and the valve body.
