Abstract
The utility model discloses a vortex street flowmeter with a moisture-proof function. The vortex street flowmeter comprises a probe, a circuit board as well as a meter body, a meter rod and a meter head which are connected sequentially, wherein the probe is located in the meter body provided with a vortex generator inside; the probe and the meter body are sealed through one flat sealing gasket; the meter head is provided with a circular-truncated-cone-shaped sealing groove; dual-layer sealing is performed on the meter head and the meter rod through the other flat sealing gasket and a circular-truncated-cone-shaped sealing gasket; and a lead of the probe penetrates through small holes in middle parts of the flat sealing gasket and the circular-truncated-cone-shaped sealing gasket in the dual-layer sealing to reach the circuit board inside the meter head. According to the vortex street flowmeter, the defect that the circuit board is damped due to the fact that ordinary flat sealing gaskets are poor in sealing effect and steam enters the meter head along the lead of the probe under the effect of high pressure during measurement of the steam or the superheated steam is overcome, permanent normal work of the vortex street flowmeter can be guaranteed, and the vortex street flowmeter has the advantages of simple structure, capability of improving the measurement precision and the like.
Description
Technical field
The utility model relates to a kind of instrument and meter of measuring pipeline fluid flow, specifically a kind of vortex shedding flow meter with moisture-proof function.
Background technology
Vortex shedding flow meter is most for measuring the flow of steam or superheated vapor, and when measuring steam or superheated vapor, gas easily enters gauge outfit along probe lead wire at High Pressure, and wiring board is made moist.Vortex shedding flow meter can all be provided with sealing in probe and table body junction, table bar and gauge outfit junction, but this sealing effectiveness is bad, of long duration easily lax.
Utility model content
The utility model, in order to address the above problem, provides a kind of truncated cone-shaped sealing means simple in structure, makes vortex shedding flow meter have moisture-proof function, guarantees the permanent normal work of vortex shedding flow meter.
The purpose of this utility model is to adopt following technical proposals to realize:
A vortex shedding flow meter with moisture-proof function, comprises probe, wiring board, and the table body connecting successively, table bar and gauge outfit; Described probe is positioned at the table body that is provided with eddy generator, between probe and table body, by sealing plain cushion, seals; Described gauge outfit, with truncated cone-shaped seal groove, adopts sealing plain cushion and truncated cone-shaped sealing gasket double-layer seal between gauge outfit and table bar, and the lead-in wire of probe arrives wiring board in gauge outfit through sealing the middle aperture of plain cushion and truncated cone-shaped sealing gasket in described double-layer seal.
Due to table body with pop one's head between have and between plain cushion sealing, gauge outfit and table bar, have plain cushion and truncated cone-shaped pad double-layer seal; can effectively stop the moisture of medium to enter in gauge outfit; thereby protection vortex shedding flow meter wiring board does not make moist, and has extended the serviceable life of vortex shedding flow meter.
Truncated cone-shaped sealing means, is when the truncated cone-shaped sealing gasket between gauge outfit truncated cone-shaped seal groove and table bar is squeezed power sealing, the power that truncated cone-shaped sealing gasket is all sealed at vertical and horizontal, and its sealing effectiveness is more a lot of than the good sealing effect of plain cushion.
The beneficial effects of the utility model are, solved when measuring steam or superheated vapor, conventional seals plain cushion sealing effectiveness is bad, High Pressure makes gas enter gauge outfit along probe lead wire, and the defect that wiring board is made moist, can guarantee the permanent normal work of vortex shedding flow meter, and have simple in structure, improved the advantages such as measuring accuracy.

Fig. 3 is the structural representation of truncated cone-shaped sealing gasket of the present utility model.
In figure, 1-eddy generator, 2-probe, 3-table body, the 4-the first sealing plain cushion, 5-table bar, 6-truncated cone-shaped sealing gasket, the 7-the second sealing plain cushion, 8-gauge outfit, 9-wiring board.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of vortex shedding flow meter with moisture-proof function, comprises probe 2, wiring board 9, and the table body 3 connecting successively, table bar 5 and gauge outfit 8; Described probe 2 is positioned at the table body 3 that is provided with eddy generator 1, between probe 2 and table body 3, by the first sealing plain cushion 4, seals; Described gauge outfit 8 is with truncated cone-shaped seal groove, and between gauge outfit 8 and table bar 5, by the second sealing plain cushion 7 and truncated cone-shaped sealing gasket 6 double-layer seals, the lead-in wire of probe 2 arrives the wiring board 9 in gauge outfit 8 through the aperture in the middle of the second sealing plain cushion 7 and truncated cone-shaped sealing gasket 6.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
