Description
Technical field
the utility model belongs to hot field of measuring techniques, more particularly, relates to the calorimeter rectilinearity stationary installation in a kind of calorimeter calibrating installation.
Background technology
At present, popularize rapidly by the method for heat metering in order to change the irrationality of heat supply by area metering
.And the metering of heat realizes by calorimeter, and calorimeter is made up of flowmeter, heat detector and counter, is respectively applied for metered flow, temperature and calculates heat.The accuracy of calorimeter then need lean on the calorimeter calibrating installation to realize demarcating and detecting.The calorimeter calibrating installation provides and approaches desirable flow field and stationary temperature, and numerical value and standard figures that calorimeter calculates are compared, and confirms the accuracy of calorimeter.
are because the stability in flow field is very big to the accuracy influence of calorimeter; Therefore, when the stationary heat scale, desirable flow field the emphasis that then becomes the calorimeter calibrating installation is provided.Existing calorimeter calibrating installation mainly is to be made up of support, guide rail, expansion bend, straight length etc., several calorimeters and straight length is cascaded through track and support location, and is clamped by expansion bend, provides the operating mode of different flow to examine and determine by water pump.The stability in flow field depends on the linearity that back straight length and calorimeter are installed, and this linearity is controlled through track and support.The guide rail that existing calorimeter calibrating installation adopts mainly is the form that adopts the form (Fig. 5) of steel plate flanging or the base table top done hollow out; The form of this track is difficult to guarantee that accurate linearity reaches in the depth of parallelism of surface level, and long-term use of warp can be out of shape in generation; These all can cause the calorimeter measurement result deviation to occur, or repeatedly measure and do not have repeatability.
Summary of the invention
the utility model is exactly to the problems referred to above, remedies the deficiency of prior art, and the calorimeter rectilinearity stationary installation in the high calorimeter calibrating installation of a kind of measuring accuracy is provided.
for realizing the above-mentioned purpose of the utility model, the utility model adopts following technical scheme.
the utility model comprises the bearing plane; Its structural feature is: described bearing plane is provided with line slideway; Described line slideway is provided with at least two slide blocks; Be provided with straight length in the pipeline section support of described slide block top, be provided with calorimeter between described adjacent two straight lengths; The straight length that is positioned at the outermost both sides links to each other with expansion bend with the stiff end support respectively.
As a kind of improvement of the utility model, described bearing plane is two, and is parallel to each other
; Correspondingly line slideway is two, and the slide block quantity that is provided with on two line slideways is identical, and with respect to straight length symmetry in twos.The effect of this structure is: when calibrating larger caliber calorimeter, eliminate because the stressed energy imbalance that the calorimeter deadweight produces.
As a kind of preferred version of the utility model, described line slideway is to be processed by stainless steel material
; Or process by the GCr15 material; Or process by nylon material.Its effect is: adapt to different installation requirements and cost requirement.
The beneficial effect of
the utility model: the utility model adopts high-precision line slideway and slide block to cooperate; And the pipeline section support of fixing internal model making; Guarantee that each straight length equates with the line slideway distance, thereby improved the measuring accuracy of the calorimeter in the calorimeter calibrating installation.
