Description

Technical Field

[0001] The utility model belongs to the technical field of vortex flowmeters, in particular to a vortex flowmeter with a leakage protection structure. Background Art

[0002] Currently, the vortex flowmeters on the market all use a closed installation structure between the probe and the support rod, and an open connection design is also adopted between the probe and the converter. However, the vortex flowmeters on the market have no way to change the heat dissipation of the probe and cannot ensure the optimal operating conditions of the converter. Utility Model Content

[0003] The utility model aims to provide a vortex flowmeter with a leakage protection structure to solve the technical problem that there is no way to change the heat dissipation of the probe part and the best working condition of the converter cannot be ensured.

[0004] To achieve the above purpose, the specific technical solution of a vortex flowmeter with a leakage protection structure of the utility model is as follows:

[0005] A vortex flowmeter with a leakage protection structure comprises a square base, a cross-groove support rod base, a connecting rod, a sealing fastening nut and a converter. The square base is provided with a cross-groove support rod base, the cross-groove support rod base is fixedly installed at one end of the connecting rod, and the other end of the connecting rod is provided with a converter via a sealing fastening nut.

[0006] Furthermore, a polyfluoroethylene sealing gasket is provided between the sealing fastening nut and the connecting rod.

[0007] Furthermore, the square base is connected to one end of the elongated vortex probe, and the other end of the elongated vortex probe is connected to the support rod base with a milled cross groove.

[0008] Furthermore, the polytetrafluoroethylene sealing gasket ensures that the connecting rod is completely isolated from the converter.

[0009] Furthermore, the extended vortex street probe is coaxially arranged with the connecting rod.

[0010] The advantages of the utility model are:

[0011] 1. The support rod base adopts a milling groove design, which is conducive to the heat dissipation of the probe and improves the life of the probe. When the medium leaks in the probe, it can also reduce the pressure impact in the connecting rod cavity and effectively protect the probe;

[0012] 2. The probe adopts an extended rod design, which not only shields the signal line, but also protects the signal line and the sealing part when the medium leaks. The probe rod is extended to the top of the connecting rod to facilitate the tightening and sealing of the nut;

[0013] 3. The sealing treatment of the probe rod can completely isolate the connecting rod from the converter. When the measuring medium leaks, it can effectively prevent the medium from entering the converter and damaging the converter. BRIEF DESCRIPTION OF THE DRAWINGS
