Description

A kind of sealing calorie meter

Technical field

This utility model relates to the calorie meter of a kind of Physical Experiment, particularly relates to the calorie meter that a kind of sealing is good.

Background technology

Calorie meter is a kind of attemperator for measuring internal system thermal change situation.Calorie meter has many types, Calorie meter kind conventional in Physical Experiment is as it is shown in figure 1, inner core 2 contacts sealing by cushion rubber 13 with glue lid 14, and urceolus 1 is straight Connect and contact sealing with glue lid 14, the problem existed:

One is that glue lid 14 is made for hard rubber, slightly deformation or air spots, just bad sealing so that the material in inner core Having heat exchange with outside, the thermal insulation making calorie meter system is bad.

Although two be inner core 2 be to contact sealing with glue lid 14 by cushion rubber 13, but inner core 2 and urceolus 1 are in the height direction Still wanting tightly to contact with glue lid 14 to ensure to seal, this is belonging to unreasonable structure, the most actually in structure designs simultaneously Due to the problem such as the accuracy of manufacture and thermal expansion, cannot realize, i.e. be difficult to ensure that the upper surface of cushion rubber 13 and the upper edge of urceolus 2 All just, just contacting with the corresponding site of glue lid 14, reach the purpose sealed, this is that calorie meter is difficult to ensure that the basic of sealing Problem.

Utility model content

The purpose of this utility model is to provide a kind of sealing calorie meter, overcomes the deficiency of background technology, is applied to physics real In testing, calorie meter system is made to have good heat-insulating property.

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

A kind of calorie meter that seals is as in figure 2 it is shown, include: urceolus 1, inner core 2, arc along 8, taper along 9, packing ring 12 and Jiao Gai Assembly, wherein glue cap assembly includes annular groove 3, agitator jack 4, thermowell 5, ebonite lid 6, flexible glue lid 7, bulge loop 10, cone Body 11.

Detailed description of the invention

A kind of calorie meter that seals of the present utility model, the cylinder of the bottom end closure that inner core 2 is made for metal, on nozzle edge to Outer bevel, i.e. has taper along 9；The cylinder of the bottom end closure that urceolus 1 is made for metal, along outwards making circular arc on nozzle Shape, i.e. has arc along 8.Inner core 2 is placed in the bottom in urceolus 1 by adiabatic packing ring 12, leaves between inner core 2 and urceolus 1 Uniform gap.

Ebonite lid 6 is the cylinder made with the hard rubber of shore hardness 80HA～90HA, as the skeleton part of Jiao Gai, Flexible glue lid 7 is made with the soft rubber with favorable elasticity, and the shore hardness of flexible glue lid 11 is 20HA～30HA.Above two hardness Rubber market all have sale, as Shenzhen Suyuan Industrial Co., Ltd. produce elastomeric material in above-mentioned hardness range Meet requirement.

Described ebonite lid 6 and flexible glue lid 7 stick together with bonding agent and form one, form glue cap assembly, and at Jiao Gai On be shaped with agitator jack 4 and thermowell 5.

So ebonite lid 6 is as the skeleton part of glue cap assembly, it is ensured that glue cap assembly the most indeformable；Flexible glue lid 7 is used With the arc along 9, on urceolus 1 with the taper on inner core 2 along 8 contact time, local deformation can be produced, to guarantee inner core 2 and outer Cylinder 1 all can keep tightly contacting with glue cap assembly simultaneously.

Of the present utility model a kind of sealing calorie meter, preferably detailed description of the invention is as shown in Figure 2 for it.

First by agitator used in the agitator jack 4 that the side of flexible glue lid 7 is inserted glue cap assembly, used Thermometer inserts in the thermowell 5 on glue cap assembly；Then test substance is put into inner core 2 and uses rapidly and smoothly Glue cap assembly covers on inner core 2 and the urceolus 1 of calorie meter, after glue cap assembly hands is gently exerted pressure, and the bullet on flexible glue lid 7 Taper on 11 embedding inner cores 2 is along 9, and the arc on urceolus 1 embeds in the annular groove 3 along flexible glue lids 7 along 8, and calorie meter just can be just Often work.

On glue cap assembly, inner core 2 and glue cap assembly have a contact height in the height direction, and urceolus 1 is total with Jiao Gai Become also to have a contact height, two contact height differences on glue cap assembly, there is a difference in height.Wanting glue cap assembly can be same Time inner core 2 is closed with urceolus 1, this difference in height must be exactly equal to the actual height of the inner core 2 of calorie meter with urceolus 1 Difference, but this is impossible, and this is belonging to unreasonable structure in structure designs, the most actually due to the accuracy of manufacture, thermal expansion, The problems such as buckling deformation and also some intermediate links, cannot realize, i.e. be difficult to ensure that glue cap assembly and urceolus 1 and inner core The upper edge of 2 contacts the most just, reaches the purpose sealed, and this is the root problem that existing calorie meter is difficult to ensure that sealing.

And in a kind of sealing calorie meter of the present utility model, owing to flexible glue lid 7 integral hardness is the lowest, there is good bullet Property, and it is shaped with 3 bulge loops 10 on the surface of bullet 11, so the bullet 11 on flexible glue lid 7 embeds the taper on inner core 2 Time along 9, be first that contacting along 9 with taper of the different degree of 3 bulge loops 10 is deformed, bullet 11 when glue cap assembly to Under also can produce little deformation time there is pressure；Simultaneously the arc of urceolus 1 along 8 contact with the annular groove 3 on flexible glue lid 7 time because Being linear contact lay, easily the bottom of annular groove 3 being produced bigger pressure, so being the most easily deformed.So when inner core 2 and urceolus The actual height difference of 1 changes, or on glue cap assembly, difference in height between two contact points changes, or interior Cylinder 2, the upper of urceolus 1 all can be made up because of the deformation of flexible glue lid 7 along shortcomings such as injustice, glue lid warpages, i.e. flexible glue lid 7 exists All can upper along contact with inner core 2 and urceolus 1 all the time in deformation, it is ensured that inner core 2 and the sealing of urceolus 1.

The tapering of bullet 11 is slightly larger than the tapering along 9 of the taper on inner core 2, it can be ensured that when bullet 11 surface and Taper on inner core 2 along 9 lower along contact time, produce bigger pressure and deform, and less deformation will be in height side When fooled inner core 2 and urceolus 1 actual height difference produce large change, inner core 2 and the sealing of urceolus 1 can be ensured.

3 bulge loops 10 that bullet 11 surface is shaped with further increase the deformation range of flexible glue lid 7, further raising amount The sealing of hot device.

Arc is made along 8 in the upper edge of urceolus 1, and the intensity that can increase urceolus 1 prevents deformation, can guarantee that again urceolus 1 is with soft Glue lid 7 is linear contact lay, increases contact pressure；Annular groove 3 also can increase the sealing of urceolus 1.

Compared with prior art, the design has two important feature:

One is to have employed ebonite lid 6 and flexible glue lid 7 to bond together composition glue cap assembly, both can guarantee that the total of glue cap assembly Body rigidity, is unlikely to deform, and easily can be deformed in required local again, to ensure the sealing of calorie meter.

Two is along using taper along 9 on inner core 2, coordinates with flexible glue lid bullet 11, and is shaped with on the surface of bullet 11 Bulge loop 10, further increases the deformation range of flexible glue lid 7, it is ensured that inner core 2 and urceolus 1 produce large change in actual height difference Time, inner core 2 and the sealing of urceolus 1 can be ensured, from principle, solve the sealing problem increasing calorie meter.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in Change or replacement, all should contain within protection domain of the present utility model.
