Description
Technical field
The utility model belongs to the thermopair in the temperature sensor field, especially a kind of sealing resistance leakage formula thermopair.
Background technology
Thermopair is one of temperature sensor of using always, the structure of the armoured thermocouple that generally uses in the industry spot mainly is made of terminal box, protective casing and temperature element at present, at the inner temperature element of armoured thermocouple is the measured place of directly guiding to the protective casing front end from terminal box, there are the following problems for this traditional structure: 1. inside do not seal the resistance neglected loading put, in case sleeve pipe and temperature element are damaged, high temperature or strong corrosive medium can directly enter in the terminal box, have great potential safety hazard; 2. the length of measuring sensor can not be adjusted, in case when design length taking place not being inconsistent with physical length, can't adjust, causes the measured temperature station temperature generation error required with reality; 3. in a single day thermopair is damaged, can only integral replacing, and cause the maintenance maintenance cost too high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sealing resistance leakage formula thermopair is provided, the temperature element adjustable length of this thermopair, and can change separately, sealingly secure is higher, and is easy to operate, long service life.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of sealing resistance leakage formula thermopair; by terminal box; protective casing and temperature element constitute; protective casing is by on last protective casing and the following protective casing; coaxial installation forms down; last protective casing upper end is packed on the terminal box; coaxial the placing in the protective casing and on it of temperature element is packed on the terminal box; wherein coaxially between last protective casing and following protective casing install a resistance and leak sealing socket; this resistance is leaked the upper end of sealing socket by the coaxial protective casing of installing of an active locknut; the lower end of this resistance leakage sealing socket is coaxial to install with following protective casing, leaks the resistance neglected loading that compresses that temperature element is installed on sealing socket in this resistance and puts.
And described resistance is leaked sealing socket and is packed on the joint flange.
And, describedly compressing the resistance neglected loading and put by hold-down bolt, pressure pad and graphite grazing pad and constitute, temperature element passes the axle center of hold-down bolt, pressure pad and graphite grazing pad, and hold-down bolt leaks the sealing socket engagement with resistance and also compresses pressure pad and graphite grazing pad.
And the upper end of described temperature element in last protective casing installs a high temperature joint, is filled with high-temp glue in this high temperature joint.
And, describedly between protective casing on the active locknut position and following protective casing, an O-ring seal is installed.
Advantage of the present utility model and beneficial effect are:
1. the last protective casing lower end of this sealing resistance leakage formula thermopair installs a resistance leakage sealing socket by an active locknut; following protective casing upper end is packed in resistance and leaks the sealing socket lower end; temperature element is put and is fixed on resistance and leaks on the sealing socket by compressing the resistance neglected loading; after this kind structure can prevent effectively that protective casing from damaging; measured medium is excessive, has improved the security of thermopair.
2. the upper end of this sealing resistance leakage formula thermocouple temperature measurement element installs a high temperature joint, and can high-temp glue in this high temperature joint can effectively improve security, when temperature element damages, prevents that the deep-etching measured medium from entering terminal box inside by temperature element inside.
3. the utility model is simple in structure, and design science is reasonable, the temperature element adjustable length of thermopair, and can change separately, sealingly secure is higher, and is easy to operate, is long sealing resistance leakage formula thermopair in a kind of serviceable life.
