Abstract
The invention discloses a thermocouple with a buffer function, and relates to the field of preparation of a thermocouple sleeve. A main body comprises a junction box and an insulation sleeve, the junction box is arranged at the top portion of the insulation sleeve, the insulation sleeve is internally provided with a thermal electrode, the insulation sleeve is divided into an upper insulation sleeve and a lower insulation sleeve, the upper insulation sleeve and the lower insulation sleeve are connected by use of a stud and a nut, the stud is of a hollow structure, the thermal electrode passes through the stud, the bottom of the upper insulation sleeve is provided with a ball head, the top portion of the lower insulation sleeve is provided with a ball socket, the ball head is arranged in the ball socket, the stud penetrates the ball head and the ball socket, and a spring pad is arranged between the nut and the stud. The thermocouple with the buffer function has the following advantages: the design is novel, the structure is simple, through arrangement of the ball head and the ball socket, the insulation sleeve is buffered and damped, the overall firmness performance is improved, and the thermocouple is more durable.
Description
Technical field
The present invention relates to thermocouple sheath preparation field, be specifically related to a kind of thermopair with pooling feature.
Background technology
Thermopair is temperature element conventional in temperature measuring instrument, its direct measuring tempeature, and temperature signal is converted to thermopower signal, is converted to the temperature of measured medium by electric meter (secondary instrument).The profile of various thermopair is often far from it because of needs, but their basic structure is roughly the same, usually by thermode, the major part compositions such as insulation sleeve protection tube and terminal box, usually and Displaying Meter, recorder and electronic controller support the use, thermopair its be mainly used in the measurement that liquid materials carries out temperature, thermopair is in the application of reality, because it is Precision measurement tools, therefore it all can be equipped with sleeve pipe in use, but when some fluid media (medium) flow velocitys are excessive, a lot of thermopair all can affect measuring accuracy in impact, even also casing failure can be caused, damage thermopair.
Summary of the invention
It is simple that technical matters to be solved by this invention is to provide a kind of structure, the thermopair with pooling feature of decompression antidetonation.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of thermopair with pooling feature, main body comprises terminal box and insulating sleeve composition, it is characterized in that: described set of terminal box is at the top of insulating sleeve, thermoelectricity level is provided with in described insulating sleeve, described insulating sleeve is divided into insulating sleeve and lower insulating sleeve, a stud nut is adopted to be connected between described upper insulating sleeve with lower insulating sleeve, described stud is hollow-core construction, described thermoelectricity level is passed by stud, the bottom of described upper insulating sleeve is provided with a bulb, the top of described lower insulating sleeve is provided with a ball-and-socket, described bulb is arranged in ball-and-socket, described stud runs through bulb and ball-and-socket, a spring shim is provided with between described nut and stud.
Described upper insulating sleeve with lower insulating sleeve top outside by an O-ring seal close, play sealing effect, avoid fluid media (medium) to enter wherein.
Be provided with a bradyseism pad between described upper insulating sleeve and lower insulating sleeve, avoid rubbing between insulation tube and lower insulation tube and impaired.
Described lower insulating sleeve is provided with one and stretches into oiling passage between bulb ball-and-socket, be convenient to internally charging-up lubricant oil.
The invention has the beneficial effects as follows: the present invention is novel in design, structure is simple, and the setting of bulb ball-and-socket, plays and carry out bumper and absorbing shock to insulating sleeve, improves integral firmness energy, more durable in use.
