Description
Technical field
The utility model relates to a kind of plug seat for vortex shedding flow meter, is a kind of plug seat sealed.
Background technology
Vortex shedding flow meter is used for the flow measuring steam or superheated vapor, and when measuring steam or superheated vapor, gas, under High Pressure, easily enters converter along connecting link or probe lead wire, causes internal circuit board component condensate water pearl and makes moist.Vortex shedding flow meter can design gasket seal at probe and pedestal junction, connecting link and converter junction, prevents pipeline from leaking gas, 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 that prior art exists, the utility model provides a kind of plug seat for vortex shedding flow meter, be a kind of structure simple plug seat sealing means, make vortex shedding flow meter avoid converter ease gas when measuring steam or superheated vapor, guaranteeing that circuit board is dry, normally working.
The utility model for achieving the above object, adopt technical scheme to be: a kind of plug seat for vortex shedding flow meter, comprise connecting link, it is characterized in that: also comprise O type circle, Cross Recess Head Screw, plug gland, seal rubber plug, filling material, 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 to be fixed on plug base upper surface by several Cross Recess Head Screw and to be compression fit with seal rubber plug, two described probe wires are arranged in plug base tube, one end of two probe wires is stretched out outside two string holes I on plug gland through two string holes II on seal rubber plug, the other end of two probe wires stretches out outside two string holes III on cylinder plug, described filling material is poured in plug base tube internal fixtion probe wire, described plug base is arranged on threaded in connecting link, described O type circle is arranged in the O type ring recess between plug base and connecting link and realizes sealing function.
The beneficial effects of the utility model are: due to plug chassis interior design bottom cylinder plug and top seal plug double sealing structure; and adopt epoxy resin or the inorganic glue static probe line of solidification; the design of plug base exterior adopts O type circle and coating butter press seal; from inside and outside duplicate protection probe wire; can steam be effectively stoped to enter gauge outfit along probe wire; thus protection vortex street converter inside circuit board dry environment; avoid steam to invade converter and reduce vortex shedding flow meter service precision, be delayed the serviceable life of vortex shedding flow meter.Bottom cylinder plug and two ends, top are the seal rubber plug of the conical surface, and between plug gland and connecting link during 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: solve when measuring steam or superheated vapor, conventional seals flat gasket effect is bad, High Pressure makes gas enter gauge outfit along probe lead wire, cause the defect of circuit board short circuit, can forever normally work by guaranteed flow meter, the utility model, under the prerequisite improving measuring accuracy, simplifies structural design further, reduces production cost.
