Description

Technical Field

[0001] The utility model relates to the technical field of an insertion barrel type remote transmission flange transmitter, in particular to an insertion barrel type remote transmission flange transmitter. Background Art

[0002] The remote flange level transmitter is a high-precision, high-stability, multi-parameter pressure / liquid level measurement product that complies with the HART protocol. This transmitter is welded on the differential pressure transmitter structure with a capillary remote flange and filled with silicone oil to avoid direct contact between the medium and the differential pressure transmitter diaphragm.

[0003] In the prior art, the diaphragm on the flange of the remote flange level transmitter can be made of different materials according to the characteristics of the medium. It is suitable for level measurement of high temperature, corrosive, suspended, viscous, easy to crystallize and other media.

[0004] However, when the existing remote flange level transmitter measures a medium that is easy to crystallize, the medium will crystallize on the pressure-sensitive diaphragm, resulting in inaccurate measurement. Therefore, we provide an insertion cylinder type remote flange transmitter to solve the problem of the medium crystallizing on the pressure-sensitive diaphragm. Utility Model Content

[0005] The utility model aims to provide an insertion cylinder type remote transmission flange transmitter to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange, an insertion tube is arranged at the bottom of the flange, a pressure-sensitive diaphragm is arranged in the middle of the bottom of the insertion tube, a mounting groove is opened inside the top of the pressure-sensitive diaphragm of the insertion tube, a heating tube is installed in the mounting groove; and a base, two connecting cables are connected to the side of the base, and the other ends of the two connecting cables are respectively connected to a group of flanges.

[0007] Preferably, a dashboard is installed on the top of the base, and the dashboard can display the detection result of the medium through a display screen on the dashboard.

[0008] Preferably, a flange handle is provided on the top of the flange, which can be used to conveniently lift and move the flange. Flange holes are provided around the flange, through which the flange can be installed on a connecting pipe equipped with a flange to detect the medium in the pipe.

[0009] Preferably, the middle of the top of the pressure-sensitive diaphragm is connected to a capillary tube, and the capillary tube is filled with silicone oil. The pressure-sensitive diaphragm can transmit pressure information to the capillary tube to control the flow of the silicone oil.

[0010] Preferably, a plurality of mounting grooves are provided at the top of the insertion tube, the mounting grooves are located around the top of the pressure-sensitive diaphragm, a heating tube is provided in the mounting groove, a heating wire is provided in the heating tube, and the heating tube can dissipate heat through the heating wire to heat the heating tube at the bottom of the mounting groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] According to the present invention, if the measured medium is a liquid that is easy to crystallize, the pressure-sensitive diaphragm is driven to penetrate into the measured medium by inserting the through tube. In the case of a medium that is easy to crystallize, heating is generally added so that the pressure-sensitive diaphragm is in the same temperature environment as the medium and is not prone to crystallization. When the detection is completed and the flange is removed, the heating tube inserted into the mounting groove at the bottom of the through tube can be turned on by controlling the heating tube to start emitting heat through the heating wire, thereby heating the pressure-sensitive diaphragm inserted at the bottom of the through tube, thereby preventing the liquid that is easy to crystallize adhered to the pressure-sensitive diaphragm from crystallizing and causing difficulty in cleaning.
