Description
Technical field
The utility model relates to pressure detection, calibrating installation, particularly a kind of pressure detection structure and calibration equipment thereof of being convenient to verification.
Background technology
Pressure-detecting device is very extensive industrial application, pressure-detecting device commonly used comprises tensimeter, pressure unit, differential pressure transmitter etc., relevant regulations according to measurement verification, pressure-detecting device needs periodic check, with the accuracy of guaranteeing to detect, and detection method is delivered to the laboratory calibration after normally pressure-detecting device being removed from the scene, wastes time and energy.And the process units that some enterprises are arranged is operation continuously, what have may be not have parking maintenance in several years, make during ordinary production, deviation appears in some pressure-detecting devices, the true value of the shown non-at-scene detection of force value, make production run depart from the desired normal value of technology, influence is produced.
Summary of the invention
But the purpose of this utility model is the pressure detection structure of being convenient to verification and the calibration equipment thereof of a kind of on-line testing of providing for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the pressure detection structure of being convenient to verification that the utility model is designed, comprise connecting pipe, connecting pipe is provided with stop valve, the end of connecting pipe is provided with pressure sensing cell, it is characterized in that connecting pipe is connected with a calibration tube, calibration tube is provided with second stop valve, and the calibration tube other end is the verification interface.
The above-mentioned calibration equipment of being convenient to the pressure detection structure of verification that the utility model is designed, comprise correction card, it is characterized in that described correction card is a U type pipe pressure meter, this U type pipe pressure meter one end is an atmospheric air port, the other end connects a flexible pipe, the pressure inlets of the other end of flexible pipe for being connected with the verification interface.During use, only need the pressure inlets of flexible pipe is connected with the verification interface of calibration tube, open second stop valve and just can from U type pipe pressure meter, read pressure easily, and compare with the shown force value of pressure-detecting device, if both shown pressure are consistent, can determine that then pressure-detecting device is working properly; If both deviation occurs, then show the pressure-detecting device possible breakdown, thereby further check or keep in repair.Used U type pipe pressure meter is demountable, if with suspicion to data, can change one or many U type pipe pressure meters and measure.
The utility model is resulting is convenient to the pressure detection structure of verification and the beneficial effect of calibration equipment is:
1, is convenient to fast, intuitively the operation pressure parameter judged whether it is true value.
2, simple to operate, do not need the dismounting pressure-detecting device just can carry out verification.
3, U type pressure unit reading is directly perceived, is convenient to the comparison of numerical value, and its dismounting is also very convenient, and the time spent can safe storage.
Description of drawings
Fig. 1 is the structural representation that embodiment 1 is convenient to the pressure detection structure of verification;
Fig. 2 is the structural representation of embodiment 1 calibration equipment;
Fig. 3 is existing combustion chamber draft measurement structure figure;
Fig. 4 is the combustion chamber draft instrumentation plan that adopts the utility model scheme.
Among the figure: connecting pipe 1, stop valve 2, pressure sensing cell 3, calibration tube 4, second stop valve 5, verification interface 6, U type pipe pressure meter 7, atmospheric air port 8, flexible pipe 9, pressure inlets 10, burner hearth 11, pressure measuring valve 12, blowoff valve 13.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the pressure detection structure of being convenient to verification that present embodiment is described, comprise connecting pipe 1, connecting pipe 1 is provided with stop valve 2, the end of connecting pipe 1 is provided with pressure sensing cell 3, it is characterized in that connecting pipe 1 is connected with a calibration tube 4, calibration tube 4 is provided with second stop valve 5, and calibration tube 4 other ends are verification interface 6.
The calibration equipment of the pressure detection structure of being convenient to verification that present embodiment is described, comprise correction card, it is characterized in that described correction card is a U type pipe pressure meter 7, these U type pipe pressure meter 7 one ends are atmospheric air port 8, the other end connects a flexible pipe 9, the pressure inlets 10 of the other end of flexible pipe 9 for being connected with verification interface 6.
Measurement with this enterprise Coal stove chamber 11 negative pressure describes, there are three stoves that burn coal in this enterprise, and every stove needs burner hearth 11 negative pressure are measured, and is adjusted the frequency of induced draft fan by the measured value of negative pressure, traditional method is that the installation method of on-the-spot pressure unit as shown in Figure 3.In this case, the technologist often suspects that the shown negative pressure value of pressure unit is not real burner hearth 11 negative pressure, has lost direction when causing operating personnel to control the frequency of induced draft fan.And the instrument personnel can not determine whether pressure unit is normal on earth, cause the normal running difficulty.
The pressure detection structure of being convenient to verification and the calibration equipment thereof that use present embodiment to describe, only need on connecting pipe 1, to install additional the calibration tube 4 and second stop valve 5, as shown in Figure 4, the pressure inlets 10 of flexible pipe 9 is connected with the verification interface 6 of calibration tube 4, open second stop valve 5 and just can from U type pipe pressure meter 7, read pressure easily, thus the place of decision problem.
