CN203870051U - Press cover type calorimeter - Google Patents

Abstract

The utility model discloses a press cover type calorimeter. The press cover type calorimeter comprises an outer cylinder, an inner cylinder, a sealing rubber ring, a cylinder cover, a temperature meter insertion hole, a stirrer insertion hole and a supporting rubber ring, a seal ring groove with barbs is added on the cylinder cover of the calorimeter, and a wedge ring with the lower protruding edge is added on the outer side at the upper edge of the outer cylinder. When the press cover type calorimeter is used, a user slightly exerts pressure after the cylinder cover covers the outer cylinder, then the barbs on the ring groove of the cylinder cover can be embedded into the protruding wedge ring on the outer side at the upper edge of the outer cylinder, and heat exchange between the inside of the calorimeter and the external environment is avoided by means of mutual embedment of the cylinder cover and the outer cylinder, so that the inside of the calorimeter is isolated from the external environment to a greater degree.

Description

A kind of gland-type calorimeter

Technical field

The utility model relates to a kind of physics facility, relates in particular to a kind of gland-type calorimeter.

Background technology

Calorimeter is a kind of attemperator for measuring system internal heat situation of change.Calorimeter has many types, and if Fig. 1 is a modal class wherein, it is to be made up of inner core and urceolus and cover etc., between two inside and outside cylinders, are the air that do not readily conduct heat, the lid on urceolus, generally makes with elastomeric material, its heat transfer efficiency is low, and cover is covered tightly and can prevent there is exchange heat inside and outside cylinder.Cover two apertures, a system temperature being used in measuring cylinder, stirrer is inserted in another hole, is used for making to drop into the quick heat-shift of determinand in inner core, reaches thermal equilibrium.Existing calorimeter cover is intermediate projections (reducing heat transmits and fixing cover), and its edge is thinner, covers on urceolus.Its shortcoming is bad sealing between cover and urceolus, and there is heat conduction urceolus top edge and outside, and in the time of cover imprecision, out-of-flatness, and there is direct heat exchange outside, makes the thermal insulation of calorimeter system bad, has a strong impact on the accuracy of measurement result.

Utility model content

The purpose of this utility model is to provide a kind of simple in structure, gland-type calorimeter that insulation effect is good.

The purpose of this utility model is achieved through the following technical solutions:

A kind of gland-type calorimeter of the present utility model, comprising: urceolus 1, inner core 2, O-ring seal 3, cover 4, thermowell 5, stirrer jack 6, support cushion rubber 7.

This calorimeter has increased the closure gasket groove with barb on cover 4, the coboundary outside of urceolus 1 has also increased the cambridge ring of lower limb projection, when use, after cover 4 is covered on urceolus 1, slightly exert pressure, on cover 4 annular grooves with barb, can be embedded on the cambridge ring of projection outside the coboundary of urceolus 1, the cover of this structure has good sealing, this calorimeter is chimeric mutually by cover 4 and urceolus 1, make not produce exchange heat with external environment condition in calorimeter, calorimeter inside is hedged off from the outer world greatly.

Compared with prior art, the utility model, owing to adopting the chimeric mutually of cover 4 and urceolus 1, can effectively prevent the heat interchange in calorimeter vessel and outside cylinder, improves measuring accuracy.

Brief description of the drawings

Fig. 1 is the structural representation of existing calorimeter.

Fig. 2 is a kind of gland-type calorimeter structural representation of the present utility model.

Fig. 3 is the structure enlarged drawing of a kind of gland-type calorimeter improvement part of the present utility model.

In figure: 1, urceolus, 2, inner core, 3, O-ring seal, 4, cover, 5, thermowell, 6, stirrer jack, 7, support cushion rubber.

Embodiment

A kind of gland-type calorimeter of the present utility model, preferably embodiment is as shown in Figure 2 for it.

First support cushion rubber 7 is put into calorimeter urceolus 1, place calorimeter inner core 2 above;

Again O-ring seal 3 is put into inner core top, then in the thermowell 4 on calorimeter cover 4, install thermometer, stirrer handle inserts in the stirrer jack 6 on cover 4 simultaneously, calorimeter inner core 2 is put into after test substance, cover 4 is covered rapidly on urceolus 1, and suitably presses calorimeter end cap 4, make on cover 4 annular grooves with barb, be embedded on the cambridge ring of projection outside the coboundary of urceolus 1, tight to guarantee to coordinate between cover 4 and outer barrel 1.The complete adiabatic system of the inner formation of calorimeter, can carry out calorimetric thermometric.

The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.

Claims (1)

1. a gland-type calorimeter, comprising: urceolus, inner core, O-ring seal, cover, thermowell, stirrer jack, support cushion rubber;

On described cover, increased the closure gasket groove with barb, the coboundary of urceolus outside has also increased the cambridge ring of lower limb projection, when use, on cover annular groove with barb be embedded on the cambridge ring of projection outside the coboundary of urceolus.
