Description
Technical field
The utility model belongs to area of thermocouples, especially a kind of multipoint thermocouple of response fast.
Background technology
In the technology controlling and process step of the industries such as petrochemical complex, various catalytic reactors, the temperature control of hydrogenation reactor and synthesis reactor needs the participation of thermopair, thermopair primary structure comprises terminal box, protection tube and thermometric core body, thermometric core body is sleeved in protection tube, although this kind of structure can be measured the temperature in reactor, but because the response meeting that has certain interval to change for reactor temperature between thermometric core body and protection tube is slack-off, have certain delay for accurate control temperature of reaction, be unfavorable for the control of reactor temperature, even if having some thermometric core bodys can fit with protection tube part by bending, because reactor inner fluid produces vibration, cause thermometric core body to contact with protection tube unstable, affect accurate temperature controlling effect, part is fitted the thermometric core body response time generally more than 10 seconds.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of multipoint thermocouple of response is fast provided; this thermocouple structure is simple, design science rationally, thermometric core body is connected firmly with protection tube, response time shortening, for accurate temperature controlling provides powerful guarantee.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of multipoint thermocouple of response fast; this thermopair comprises terminal box, protection tube and thermometric core body; thermometric core body connects terminal box; protection tube is sleeved on terminal box lower end; thermometric core body is arranged on the terminal box lower end in protection tube; its thermometric core body outer wall in protection tube is set with a thermal conducting sleeve, and this thermal conducting sleeve sidewall is made heat and transmitted projection, and this heat transmission projection is embedded on protection tube wall.
And described heat transmission projection is embedded on protection tube wall and flushes integral with protection tube outer wall.
And described heat transmission projection is embedded on protection tube wall and leans out protection tube outer wall.
And, described protection tube outer wall suit flange.
And the thermometric core body in described protection tube is fixedly mounted with by clamping screw.
Advantage of the present utility model and beneficial effect are:
This is response multipoint thermocouple fast; this thermopair comprises terminal box, protection tube and thermometric core body; thermometric core body connects terminal box; protection tube is sleeved on terminal box lower end; thermometric core body is arranged on the terminal box lower end in protection tube; its thermometric core body outer wall in protection tube is set with a thermal conducting sleeve; this thermal conducting sleeve sidewall is made heat and is transmitted projection; this heat transmission projection is embedded on protection tube wall; the utility model is simple in structure, design science is reasonable, thermometric core body and protection tube are connected firmly; response time shortens, for accurate temperature controlling provides powerful guarantee.
Heat of the present utility model is transmitted projection and is embedded on protection tube wall and flushes integral with protection tube outer wall; heat on thermal conducting sleeve is transmitted protruding direct detection reactor temperature; quick and precisely demonstrate reactor temperature and by System Implementation control by thermometric core body; logical heat transfer projection is surveyed; thermopair just can complete temperature-responsive within the time that is less than 8 seconds; faster more than 2 seconds than the thermopair of common contact-type; be conducive to accurately react rapidly and control inside reactor temperature, make the reaction in reactor more steady.

Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of multipoint thermocouple of response fast; this thermopair comprises terminal box 1, protection tube 5 and thermometric core body 6; thermometric core body connects terminal box; protection tube is sleeved on terminal box lower end; thermometric core body is arranged on the terminal box lower end in protection tube, and the thermometric core body in described protection tube is fixedly mounted with by clamping screw 2.Its thermometric core body outer wall in protection tube is set with a thermal conducting sleeve 7, and this thermal conducting sleeve sidewall is made heat and transmitted projection 4, and this heat transmission projection is embedded on protection tube wall.Heat is transmitted projection and is embedded on protection tube wall and flushes integral with protection tube outer wall.Heat transmission projection of the present utility model also can be embedded on protection tube wall and lean out protection tube outer wall, and heat transmission projection and protection tube wall can adopt the form of welding, described protection tube outer wall suit flange 3.The number of the measurement core body in the utility model is determined according to the requirement of measuring point, can be Arbitrary Digit.
Each measurement core body of the present utility model is all set with a thermal conducting sleeve; this thermal conducting sleeve is arranging heat transmission projection near measurement point; and weld with protection tube; realize the measurement of temperature from extraneous medium to weld; logical heat transfer projection is transmitted to the conduction process of measuring core body again; reaction velocity is fast, and measuring point is controlled, accurate.
The utility model one is that thermal conducting sleeve and protection tube contact area are increased; The 2nd, former product contacts and carries out heat conduction with outside protective pipe inwall, and this structure impels thermal conducting sleeve can touch outside, thereby makes heat conduction faster.The 3rd, heat is transmitted projection and protection tube wall and can be adopted formal cause pad clear and definite of welding, thereby can clearly carry out the distribution of point position.
