Description

Plug-in type one-piece type temperature and pressure compensation holder hand shaft flowmeter
Technical field
The utility model relates to the field of measuring technique of fluid flow, particularly the holder hand shaft flowmeter of the one-piece type temperature and pressure compensation of a kind of plug-in type.
Background technology
The impact that the flow of gas is subject to the environmental factor such as temperature, pressure is very large, when use traffic meter measuring flow, if do not consider the impact of temperature, pressure, the result obtained and correct result have larger deviation, the error on the order of magnitude can be produced even, therefore must carry out correct temperature pressure compensation to measurement result and could obtain correct gas flow measurement data.
The compensation way of a lot of gas flow measurement adds the acquisition elements such as temperature, pressure outside original measuring system at present, signal transmission is carried out the compensation operation of gas density to equipment such as integrating instruments, its advantage is that the structure of each measure portion is simply too much, maintenance is convenient, shortcoming is system unit dispersion, pipeline adds a sensor need punching, be welded and fixed, be multiplied workload, simultaneously element, web member etc. increase the very trouble the and easily faults such as leakage occur such as the debugging that makes whole system and maintenance.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides the one-piece type temperature and pressure compensation flowmeter of a kind of novel plug-in type to solve the problems referred to above.The utility model reasonable distribution locus of various measuring sensor, makes all parts form one and measures overall, carry out the measurement of temperature, pressure and differential pressure simultaneously, and have easy to operate, safeguard economical and measure the advantages such as accurate.
For achieving the above object, the technical solution adopted in the utility model is:
The one-piece type temperature and pressure compensation flowmeter of plug-in type described in the utility model comprises differential pressure transmitter, measures three valve groups, pressure transducer, T-valve, mounting flange, mounting seat, holder hand shaft flowmeter, differential pressure output module and thermal resistance; Described mounting seat is welded on tested pipeline, and the other end is connected with mounting flange by screw thread; Holder hand shaft flowmeter is inserted in tested pipeline by mounting flange and mounting seat, and is fixed by mounting flange; Described differential pressure output module is arranged on holder hand shaft flowmeter upper end, and a thermal resistance is installed in differential pressure output module side, and opposite side connects a T-valve, installs a pressure transducer outside T-valve; Described differential pressure output module top connects one and measures three valve groups, and described measurement three valve group top is provided with a differential pressure transmitter.
Accompanying drawing explanation
Fig. 1 is plug-in type one-piece type temperature and pressure compensation holder hand shaft flowmeter one-piece construction figure;
Description of reference numerals:
1, differential pressure transmitter; 2, three valve groups are measured; 3, pressure transducer; 4, T-valve; 5, mounting flange; 6, mounting seat; 7, hand shaft flowmeter is held in the palm; 8, tested pipeline; 9, differential pressure output module; 10, thermal resistance.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, plug-in type one-piece type temperature and pressure compensation holder hand shaft flowmeter comprise differential pressure transmitter 1, measure three valve groups 2, pressure transducer 3, T-valve 4, mounting flange 5, mounting seat 6, holder hand shaft flowmeter 7, tested pipeline 8, differential pressure output module 9 and thermal resistance 10.
One end of mounting seat 6 is welded on tested pipeline 8 outer wall, and the other end is connected with mounting flange 5 by screw thread.Holder hand shaft flowmeter 7 is inserted in tested pipeline 8 by the perforate on mounting flange 5, mounting seat 6 and tested pipeline 8 tube wall, fixed by mounting flange 5 after making total head pressure port align with tube carry out flow path direction by adjustment, holder hand shaft flowmeter 7 upper end connects a differential pressure output module 9.A thermal resistance 10 is installed for trapping medium temperature information in differential pressure output module 9 side, and opposite side connects a pressure transducer 3 by a T-valve 4, and pressure transducer 3 is for trapping medium pressure information.Connect one above differential pressure output module 9 and measure three valve groups 2, differential pressure transmitter 1 is arranged on the top of three valve groups 2.
Temperature and pressure sensor element on plug-in type one-piece type temperature and pressure compensation holder hand shaft flowmeter is assembled together with holder hand shaft flowmeter, installation process does not need perforate on pipeline in addition, greatly reduce installation difficulty, reduce operating process, there is good applicability.The measured value of pressure transducer and temperature sensor is the real time data of fluid in pipeline, ensure that the accuracy of measurement.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
