Description
Technical field
The present invention relates to a kind of plug seat of vortex-shedding meter, is a kind of plug seat sealing.
Background technology
Vortex-shedding meter is used for measuring the flow of steam or superheated steam, and in the time measuring steam or superheated steam, gas, under High Pressure, easily enters converter along connecting rod or probe lead wire, causes internal circuit board component condensate water pearl and makes moist. Vortex-shedding meter can design gasket seal at probe and pedestal junction, connecting rod and converter junction, prevent pipeline gas leakage, facts have proved that this sealing effectiveness is undesirable, and easily poorly sealed or appearance sealing relaxes.
Summary of the invention
In view of the deficiency of prior art existence, the invention provides a kind of plug seat of vortex-shedding meter, be a kind of plug seat sealing means simple in structure, make vortex-shedding meter in the time of metering steam or superheated steam, avoid converter ease gas, guarantee that circuit board is dry, normally work.
The present invention for achieving the above object, the technical scheme that adopts is: a kind of plug seat of vortex-shedding meter, comprise connecting rod, it is characterized in that: also comprise O type circle, Cross Recess Head Screw, plug gland, seal rubber plug, filler, plug base, cylinder plug, probe wire, described cylinder plug is arranged on plug base tube endoporus lower end interference fit, described seal rubber plug is arranged on plug base tube endoporus upper end interference fit, described plug gland be fixed on plug base upper surface by several Cross Recess Head Screws and with seal rubber plug be compression fit, two described probe wires are arranged in plug base tube, stretch out outside two line hole I on plug gland through two line hole II on seal rubber plug one end of two probe wires, the other end of two probe wires stretches out outside two line hole III on cylinder plug, described filler is poured in static probe line in plug base tube, described plug base is arranged on threaded in connecting rod, described O type circle is arranged in the O type ring recess between plug base and connecting rod and realizes sealing function.
The invention has the beneficial effects as follows: due to plug base indoor design bottom cylinder plug and top seal plug double sealing structure; and adopt curing epoxy resin or inorganic glue static probe line; the design of plug base exterior adopts O type circle coating butter press seal; from inside and outside duplicate protection probe wire; can effectively stop steam to enter gauge outfit along probe wire; thereby protection vortex street converter inside circuit board dry environment; avoid steam to invade converter and reduce vortex-shedding meter service precision, postponed the service life of vortex-shedding meter. The seal rubber plug that bottom cylinder plug and two ends, top are the conical surface, when between plug gland and connecting rod when fit sealing, plug is all subject to sealing load at vertical and horizontal, and its sealing effectiveness is more double than the sealing effectiveness of planar sealing pad.
In a word: solved in the time measuring steam or superheated steam, conventional seals plain cushion sealing effectiveness is bad, High Pressure makes gas enter gauge outfit along probe lead wire, cause the defect of circuit board short circuit, can ensure the permanent normal work of flowmeter, the present invention is improving under the prerequisite of certainty of measurement, and further simplified structure design, has reduced production cost.
