Description
Technical field
The utility model relates to the field of measuring technique of fluid flow, particularly the Pi Tuoba flowmeter of the one-piece type temperature and pressure compensation of a kind of plug-in type.
Background technology
The accurate detection of flow is the primary foundation of measuring clearing fair and justly.The impact that gas flow is subject to temperature, pressure is very large, when use traffic meter measuring flow, if do not consider temperature pressure compensation, the result obtaining can be far from each other with correct result, and therefore must carry out correct temperature pressure compensation could obtain correct gas flow measurement data.If the element that adopts pipeline to install is realized the collection of temperature and pressure signal, the compensation operation by flow computer convection cell density such as PTB2000F and then is carried out flow rate calculation, its advantage is that Split type structure is simple, shortcoming is that installation form disperses, a temperature or pressure transducer are installed on pipeline and need to be punched in addition, be welded and fixed, simultaneously increasing of element, web member etc. makes the very trouble such as the debugging of whole system and maintenance.Current one-piece type temperature and pressure compensation flowmeter or structure are heavy, difficult in maintenance; Or error is larger, be difficult to meet measurement requirement.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide the one-piece type temperature and pressure compensation flowmeter of a kind of novel plug-in type to solve the problems referred to above, flow, three kinds of sensing elements of temperature and pressure are integrated, form a measurement integral body and there is operation and maintenance convenience simultaneously, 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 thermal resistance, differential pressure output module, two-way valve, pressure transducer, back-flushing valve, measurement three valve groups, fastener, mounting flange, sleeve, ball valve, mounting seat and Pi Tuoba flowmeter.Described mounting seat is welded on tested pipeline, and ball valve one end is welded in mounting seat, and the other end is connected with sleeve by screw thread.Described sleeve top stretches out and forms a ring flange.The ring flange on sleeve top, mounting flange and fastener are bolted, and Pi Tuoba flowmeter is fixed.Described differential pressure output module is arranged on Pi Tuoba flowmeter upper end, and differential pressure output module both sides respectively connect a two-way valve, respectively connects a back-flushing valve on two-way valve, and a pressure transducer is installed on the two-way valve of fluoran stream surface one side.Three valve groups are measured in one of the positive connection of described differential pressure output module.Described differential pressure output module upper end is provided with a thermal resistance.
Described thermal resistance inserts differential pressure output module and Pi Tuoba flowmeter, and end extend in tested pipeline by flowmeter static tube.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the one-piece type temperature and pressure compensation Pi Tuoba of plug-in type flowmeter comprises thermal resistance 1, differential pressure output module 2, two-way valve 3, pressure transducer 4, back-flushing valve 5, measures three valve groups 6, fastener 7, mounting flange 8, sleeve 9, ball valve 10, mounting seat 11 and Pi Tuoba flowmeter 12.
Mounting seat 11 is by welded and installed on tested pipeline 13 outer walls, and ball valve 10 lower ends and mounting seat 11 are welded, and the other end is connected with sleeve 9 by screw thread.Sleeve 9 head portions stretch out and form a ring flange.Together with mounting flange 8, fastener 7 are bolted with the upper end of sleeve 9, can Pi Tuoba flowmeter 12 is fixing after bolt tightening.Pi Tuoba flowmeter 12 upper ends are connected with differential pressure output module 2.Differential pressure output module 2 both sides connect respectively a two-way valve 3, and a back-flushing valve 5 is respectively installed in two-way valve lower end, and a pressure transducer 4 is installed in the two-way valve outside of fluoran stream surface one side.Three valve groups 6 are measured in one of the positive connection of differential pressure output module 2.Differential pressure output module 2 tops are provided with a thermal resistance 1.
Thermal resistance 1 successively inserts differential pressure output module 2 and Pi Tuoba flowmeter 12, and end extend in tested pipeline 13 by the static tube of Pi Tuoba flowmeter 12.
Temperature, pressure sensor part and the Pi Tuoba flowmeter of the one-piece type temperature and pressure compensation Pi Tuoba of plug-in type flowmeter are directly installed, and do not need perforate on pipeline in addition, greatly reduce installation difficulty, have good economy.The numerical value of pressure transducer reads from ram-air pipe, temperature sensor measurement be pipeline inner fluid temperature, be the real time data of fluid in pipeline, guaranteed the accuracy of measuring.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
