a process interface sealing structure of a temperature transmitter is characterized in that special movable joints are arranged at process interfaces at two sides of the temperature transmitter, each special movable joint comprises an external thread interface and an internal thread interface, and the two interfaces are connected through movable joint threads;
the inner thread interface on one side is connected with an integral bent pipe, the integral bent pipe is connected with an explosion-proof flexible pipe, the integral bent pipe and the explosion-proof flexible pipe are welded, and the flexible pipe joint is always downward;
the other side of the internal thread interface is used for connecting the primary element.
Further, the integral elbow has a camber of 130 °.
Further, a sealing gasket is further arranged between the external thread interface and the internal thread interface, and a circle of convex sealing grooves are arranged on the periphery of the sealing gasket.
Compared with the prior art, the utility model has the beneficial technical effects that:
1. by additionally installing the special movable joint at the process interface of the temperature transmitter, the replacement, installation and maintenance of the temperature measuring primary element can be performed without dismantling the temperature transmitter and the flexible pipe connecting joint, the working efficiency is improved, and the damage probability of cables, short circuits and temperature measuring elements is avoided.
2. The sealing joint provided by the utility model ensures that the flexible pipe joint of the temperature transmitter can not enter water of the long-protection transmitter in normal and abnormal working states in practice through the matching design of welding, plane sealing, thread sealing and installation modes, the flexible pipe joint is always downward, and rainwater or gas can not enter the temperature transmitter through the flexible pipe and the connecting part thereof.
3. The customized sealing gasket has better sealing effect than the common gasket through the special protruding sealing groove.
