Abstract
The utility model discloses a tower-shaped flow meter with a heating function, which has the advantages of preventing medium from crystallizing, adhering and freezing and improving the measurement precision. The tower-shaped flow meter comprises a measuring pipe and a V-shaped throttling element fixedly connected in the cavity of the measuring pipe, a heating device is mounted in the V-shaped throttling element and/or the outer side of the pipe wall of the measuring pipe, a temperature measurement element is further mounted on the V-shaped throttling element, and is connected with a detecting instrument through a cable.
Description
Technical field:
The utility model belongs to the technology of instrument and meter field of measuring the pipeline fluid flow, is specifically related to a kind of turriform flowmeter with heating function.
Background technology:
Conventional V cone flow meter contains the gas flow of dust, particle, naphthalene, tar or environment temperature is too low when causing medium to be lower than zero degree in measurement, though this instrument has the function that automatically cleaning purges, prevent dust granules on throttling element, the measuring tube inwall is piled up and stop up pressure port, but prevent naphthalene and tar the crystallization of throttling element surface, measuring tube inwall and the effect of adhering to a little less than, do not have especially as for antifreeze function.Thereby measuring error is increased greatly, even flowmeter cisco unity malfunction.
Summary of the invention:
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of method by heating can prevent the medium crystallization, adhere to, prevent that medium from freezing, and improves the turriform flowmeter with heating function of measuring accuracy.
For achieving the above object, the utility model adopts following technical scheme:
A kind of turriform flowmeter with heating function, it comprises the V-arrangement throttling element that connects firmly in measuring tube and its cavity, and heating arrangement is installed in the V-arrangement throttling element and/or outside the measuring tube tube wall; Temperature element also is installed on the V-arrangement throttling element, and is connected with measuring instrument by cable.
Described measuring tube outer wall is provided with protective seam, is provided with insulation material between measuring tube and protective seam.
Described measuring tube two ends mounting flange.
Described V-arrangement throttling element connects firmly by stay pipe and measuring tube inner chamber.
The utility model is provided with by two ends and establishes the V-arrangement throttling element that stay pipe supports in the measuring tube of mounting flange and its cavity and form; Heating arrangement is installed in the V-arrangement throttling element and/or outside the measuring tube tube wall; The optional temperature element of establishing on the throttling element inwall, and be connected with measuring instrument by cable.Wherein,, can be provided with protective seam, between measuring tube and protective seam, be provided with insulation material at the measuring tube outer wall in order to reach better heat insulation effect.
The beneficial effects of the utility model are:
Owing to adopt technique scheme, make local rising of temperature of throttling element, measuring tube and pressure tappings by the method for heating, make near the vaporization of the naphthalene on throttling element outside surface, measuring tube inside surface and the pressure tappings inwall position, tar viscosity and reduce, under the purging function of V-arrangement awl, the naphthalene of gasification and thinning tar are along with fluid is blown to downstream line, thereby effectively prevented naphthalene and tar on throttling element outside surface and measuring tube inwall crystallization and adhere to, simultaneously prevented that also medium from freezing.Thereby has an advantage that can prevent the medium crystallization, adhere to, freeze to improve measuring accuracy.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of a kind of common type of the present utility model.
A kind of turriform (V-arrangement awl) flowmeter with heating function is provided with by two ends and establishes the V-arrangement throttling element 2 that stay pipe 3 supports in the measuring tube 1 of mounting flange and its cavity and form; Twine heating tube 4 in the measuring tube 1 tube wall outside and/or V-arrangement throttling element 2 inwalls; On throttling element 2 inwalls, be provided with temperature element 5 and be connected with measuring instrument by cable; Measuring tube 1 tube wall outer felt around heating tube 4 outsides be provided with protective seam 6, between measuring tube 1 and protective seam 6, be provided with insulation material 7.During use, turriform (V-arrangement awl) flowmeter is installed in the pipeline, the in-out end of heating tube links to each other with the heating steam pipeline by valve 8,9, can be according to the temperature or the experience of temperature element 5 measurements, and the size of control valve control heating steam amount is the temperature of may command heating.
