Today, most urban resources are transported through the urban plumbing system, including running water, gas, oil, and so on, which we need to use in our daily life. When it comes to the current pipeline delivery system, these resources are generally transported by low temperature pipeline, the low temperature valve used in the low temperature pipeline system is a main regulating device, is a kind of medium delivery more fast and stable regulating valve device. And this kind of low temperature valve actually needs to pay attention to the phenomenon of clamping when using.

In order to prevent the occurrence of valve stuck phenomenon, in the design should be used open rod structure and thick teeth trapezoidal thread; There SHOULD be a firm support AT the low temperature valve valve on the installation to prevent the valve from bending the stem due to the displacement of the valve with the pipe. The valve and the cold box can be fixed by elastic connection to prevent the stem deformation and different heart with the valve body. During THE BARE COOLING, CHECK AND ADJUST THE VALVE INSTALLATION IN THE COLD STATE. When the valve is found stuck after cooling, the fixed flange of the valve on the shell can be adjusted to enable the valve to switch freely. In operation, the heating before starting should be thorough, close the low temperature valve valve to the principle of no air leakage, do not force too hard.
