Abstract
The utility model discloses a high-voltage terminal-exposed thermocouple equipped with a hollow protection tube. The high-voltage terminal-exposed thermocouple comprises a junction box, a bushing, a high-voltage protection tube provided with a flange, one terminal of the bushing is connected with the junction box, the other terminal of the bushing is inserted into the inner cavity of the high-voltage protection tube and then penetrates through the inner cavity of the high-voltage protection tube, and a terminal part of the bushing is exposed. The terminal of the bushing inserted into the high-voltage protection tube is connected with the high-voltage protection tube via a sealing plug, and a bushing penetrating terminal of the high-voltage protection tube is provided with the hollow protection tube. The hollow protection tube reduces the impact of media to a measuring terminal of the thermocouple, the service lifetime of the thermocouple is effectively extended, and the high-voltage terminal-exposed thermocouple equipped with the hollow protection tube is advantaged by simple structure, convenient implementation, and low price.
Description
Technical field
The utility model relates to area of thermocouples, is specifically related to a kind of dew end thermopair that is provided with the hollow out protecting tube for hyperbaric environment.
Background technology
The industrial heat galvanic couple generally is divided into the band protection tube and is not with two kinds of protection tubes, thermopair intensity with protection tube is high, shock-resistant, wearing and tearing, corrosion, but thermocouple wire does not directly contact with measured medium, thermal response speed is slow, precision is low, testing environment for high pressure, must adopt the thermopair with protection tube, for overcoming its shortcoming, prior art has a kind of high pressure to reveal the end thermopair, termination is measured through exposing a part after protection tube in the end of thermopair, although can improve thermal response speed and the precision of thermopair, but the measurement termination of thermopair directly is subject to the pressure of medium, wash away, easily damage, affect serviceable life.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high pressure that is provided with the hollow out protecting tube and reveals the end thermopair, and the measurement termination that can solve existing high pressure dew end thermopair directly is subject to the pressure of medium, washes away, and causes holding flimsy problem.
The utility model is achieved through the following technical solutions:
A kind of high pressure that is provided with the hollow out protecting tube reveals the end thermopair; comprise terminal box, sleeve pipe, be provided with the high voltage protective pipe of flange; described sleeve pipe one end connects terminal box; the other end inserts the inner chamber of high voltage protective sleeve pipe; expose its end through after the inner chamber of high voltage protective sleeve pipe again; the end that described sleeve pipe inserts the high voltage protective sleeve pipe is connected with the high voltage protective sleeve pipe by seal plug, and the sleeve pipe traversing through end of described high voltage protective sleeve pipe is provided with the hollow out protecting tube.
The further improvement of the utility model scheme is that described hollow out protecting tube is made by stainless steel.
The utility model advantage compared with prior art is:
One, reduce the impact of medium to the thermocouple measurement termination with the hollow out protecting tube, effectively extend the serviceable life of thermopair;
Two, simple in structure, implement convenient, low price.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
