Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a high-pressure temperature monitoring device for a blast furnace cooling wall water temperature difference monitoring system comprises a monitoring device 1, wherein the monitoring device 1 is provided with a ball valve 2, the monitoring device 1 comprises a sensor 11 and a probe 12, the probe 12 is connected below the sensor 11, a limiting ring 13 is arranged at the joint of the probe 12 and the sensor 11, a sealing ring 131 is arranged at the edge of the limiting ring 13, a ladder-shaped connecting ring 132 is arranged below the limiting ring 13, and a fixing nut 134 is sleeved on the periphery of the limiting ring 13;

first protective sleeve 121 and second protective sleeve 122 are sequentially sleeved on probe 12, second protective sleeve 122 is worn out at the end of probe 12, the top of first protective sleeve 121 is fixed with ladder-shaped connecting ring 132, the wall thickness of second protective sleeve 122 is greater than that of first protective sleeve 121, isolation pipe 123 is further sleeved on the outer side of first protective sleeve 121, external threads are arranged on the outer wall of isolation pipe 123, the top of isolation pipe 123 is fixed with ladder-shaped connecting ring 132, and the bottom of isolation pipe 123 is fixed with the top of second protective sleeve 122.

In this embodiment, 2 both ends of ball valve are equipped with pipeline interface 21 and equipment interface 22 respectively, be equipped with connecting pipe 23 on the equipment interface 22, the inner wall of connecting pipe 23 is equipped with the internal thread, all be equipped with the external screw thread on the outer wall at the both ends of connecting pipe 23, only need with the bottom of connecting pipe 23 inserts equipment interface 22 to rotatory screwing up can fix the connecting pipe on the ball valve.

In this embodiment, the monitoring device is assembled as follows:
