Problems solved by technology
[0002] When the interlayer pipe between the inner and outer heads of the low-temperature vacuum storage tank is impacted by low-temperature liquid, the pipe will shrink to a certain extent, and when it is impacted by external force, such as mobile high-vacuum low-temperature storage tanks (low-temperature tankers, automobiles) Use liquefied natural gas cylinders), the weld seam between the interlayer pipe and the low-temperature side joint of the inner head is easy to break, resulting in internal leakage of the product, loss of vacuum, rapid vaporization of the low-temperature liquid, and increased pressure. There is a great danger and poor safety performance

The invention relates to a low-temperature liquefied gas storage groove interlay pipe fixing clamp. The fixing clamp is arranged between an inner sealing head (6) and an outer sealing head (7) and comprises a glass steel pipe clamp body (1) and a pipe clamp connecting plate (2) which are arranged up and down and connected through bolts and nuts. A connecting plate I (3) and a connecting plate II (4) are arranged on the two sides of the bottom of the pipe clamp connecting plate (2). An interlayer pipe (8) between the inner sealing head (6) and the outer sealing head (7) is fixed through the glass steel pipe clamp body (1). The connecting plate I (3) and the connecting plate II (4) are fixed to the bottom of the inner sealing head (6). Through the arrangement of the low-temperature liquefiedgas storage groove interlay pipe fixing clamp, an interlayer pipe and inner sealing head low-temperature side connector welding line is not prone to fracture, the safety performance is improved, andthe dangerous situation is avoided.
Description
technical field [0001] The invention relates to a clamp for interlayer pipes of a low-temperature liquefied gas storage tank, which is suitable for large-scale vacuum storage tanks of low-temperature liquefied gas, low-temperature heat-insulating gas cylinders and low-temperature pipelines. Background technique [0002] When the interlayer pipe between the inner and outer heads of the low-temperature vacuum storage tank is impacted by low-temperature liquid, the pipe will shrink to a certain extent, and when it is impacted by external force, such as mobile high-vacuum low-temperature storage tanks (low-temperature tankers, automobiles) With liquefied natural gas cylinders), the weld seam between the interlayer pipe and the low-temperature side joint of the inner head is easy to break, resulting in internal leakage of the product, loss of vacuum, rapid vaporization of the low-temperature liquid, and rise in pressure. There is a great danger and poor safety performance. [000...
