Description
Technical field
The utility model relates to a kind of thermopair, particularly a kind of thermopair that is used for the pipe surface thermometric.
Background technology
The thermopair that the pipe surface thermometric is used generally all is the method that adopts thermopair core and pipeline external surface welding.Its shortcoming is: 1. the thermometric degree of accuracy is low, reaction velocity is slow; 2. change and safeguard inconvenience, will destroy the weld of pipeline and thermopair when changing thermopair, after the polishing, welding again, part also needs the scene to heat-treat; 3. because the anti-explosion fire requirement, the part scene is forbidden to weld etc. naked light work; When 4. installing, sweating heat galvanic couple core and pipeline, the thermopair core damages easily, and pipeline influences the physical property of pipeline because welding produces stress.When 5. operating mode was special, the pipeline internal medium flow velocity was fast, and pipeline is directly perforate again, and temperature measurement accuracy is required when higher, and other surface thermocouples can not satisfy field requirement with welded type.
Summary of the invention
The utility model is to solve the above-mentioned technical matters that existing thermopair is occurred in the pipe surface thermometric, provides a kind of replacing easy to maintenance, the flange wafer type surface thermocouple that the thermometric degree of accuracy is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of flange wafer type surface thermocouple comprises protection tube, the thermopair core, following protection tube, flange, connecting pipe, the left and right two ends of connecting pipe are welding flange respectively, bore a blind hole on the connecting pipe length center, the degree of depth is 1/2 of a connecting pipe wall thickness, protection tube under the vertical welding on it, and the protection tube endoporus is coaxial with the connecting pipe blind hole down; Following protection tube is by the activity cutting ferrule screw that is threaded; connect upward protection tube by movable nut above the movable cutting ferrule screw; last protection tube upper port is welded with the lower interface screw; the lower interface screw thread connects terminal box; the thermopair core is successively by last protection tube; insert in the following protection tube behind the movable cutting ferrule screw; and thermopair core and movable cutting ferrule screw; following protection tube contact position is placed with two cutting ferrule taper clips respectively, and it is pullover to be provided with the spring crimping between thermopair core upper step axle upper surface and the terminal box.
The connecting pipe bore is identical with pipe diameter, and the flange bore is identical with the pipe flange bore.
The beneficial effects of the utility model are:
1, connecting pipe and two flange welding, flange is connected with pipe flange, and the connecting pipe bore is identical with pipe diameter, and the flange bore is identical with the pipe flange bore.This structure can need not welding at the scene and can install, and is fit to pipeline and the various medium and the operating mode of various bores.
2, bore a blind hole on the connecting pipe; the degree of depth is 1/2 of a connecting pipe wall thickness; following protection tube and connecting pipe welding; thermopair is connected with following protection tube by movable cutting ferrule screw; like this during maintain and replace; only thermopair directly need be changed and be got final product; compare with traditional pipe surface thermopair; need not welding; it is convenient to change; yet replaceable thermopair under the situation of equipment dispense with parking, the unnecessary wasting of resources of avoiding equipment to stop and cause can not cause the damage of thermopair and the physical property of generation stress influence pipeline because of welding yet.
3, spring compression joint type structure makes the thermopair core be close to connecting pipe blind hole top by spring force, makes thermometric more accurate, and the reaction time is faster; Overcome traditional pipe surface thermopair because pipeline wall thickness is excessive, and thermometric out of true that causes and sensitivity are low excessively.
4, in anti-neglected loading put can stop connecting pipe blind hole place because unexpected and when taking place to reveal medium outside connecting pipe, overflow, guarantee the on-the-spot safety of using, anti-in neglected loading put the highest can withstand voltage 16Mpa; Can prevent that also the rainwater in the site environment from penetrating into down in the protection tube, in a single day the thermopair head has rainwater, and displays temperature will be less than normal, thereby guarantees the accuracy of thermometric.
