The utility model is advantageous for popularization of ultrasonic flow meter.
Description
The utility model relates to supersonic technique, particularly the manufacturing of ultrasonic probe.
Utilizing ultrasonic technology to measure fluid at ducted flow, is to obtain flow by converting behind the velocity measurement mostly.Ultrasonic flow measurement speed is to utilize in the fluid velocity of propagation of ultrasound wave on a certain direction to carry out with the principle that rate of flow of fluid changes; Velocity of propagation is very fast during following current, and velocity of propagation is slower during adverse current, and the mistiming that records this both direction can calculate flow rate of fluid.The manufacturing of ultrasonic probe and mounting means are two major issues of measuring ultrasonic wave flow.In the prior art, the plug-in type ultrasonic probe often needs to stop conveyance fluid, is welded to connect head after fluid pipe walls perforation, could install, and wastes time and energy and can not optional position installation on the pipeline of having opened.In addition, the transducing sheet of ultrasonic probe is guided towards a kind of heatproof of direction needs of pipeline fluid, PEI (polyimide) material that acoustic impedance is low, existing ultrasonic probe uses the PEI material of monoblock, the material resources that waste is valuable, and manufacturing cost is high.
The utility model proposes a kind of economizing type holding ultrasound wave flowmeter probe apparatus for overcoming above-mentioned the deficiencies in the prior art part, need not to stop to carry operation, also need not any appointed part that the perforate welding can be installed in fluid line, and the PEI material of saves valuable.
The purpose of this utility model can adopt following technical measures to reach:
Design, a kind of holding ultrasound wave flowmeter probe apparatus of employing comprise probe body and the lead cable that is fastenedly connected with it; Described probe body comprises probing shell again, be installed in the transducer piezoelectric chip in this housing and be connected in coupling electronic component between this piezoelectric chip and the lead cable.Especially described housing is roughly cuboid, and this housing is provided with an installed surface; The back side of shell relative with this installed surface has a clamping lateral concave groove.
The utility model brief description of drawings is as follows:
Fig. 1 is the upward view of the utility model holding ultrasound wave flowmeter probe apparatus;
Fig. 2 looks cut-open view for the master of described probe apparatus;
Fig. 3 is the vertical view of described probe apparatus;
Fig. 4 is the use synoptic diagram that described probe apparatus is installed in institute survey pipeline upstream and downstream.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in further detail.
A kind of holding ultrasound wave flowmeter probe apparatus comprises probe body 1 and the lead-in wire concentric cable 2 that is fastenedly connected with it; Described probe body 1 comprises stainless steel probing shell 11 again, be installed in the transducer piezoelectric chip 12 in this housing and be connected in this piezoelectric chip and lead cable 2 between inductance type coupling electronic component 13.Especially described housing 11 is roughly cuboid, and this housing is provided with an installed surface, plane normally, also arc slightly; The back side of shell relative with this installed surface has a clamping lateral concave groove 111, so that can use the fixed band of broad; Described housing (11) also available copper is made.
The wedge 112 that one transversal section is set is garden shape in the described housing 11 extends out on the installed surface; Described wedge is made by low resistance PEI material (polyimide).Piezoelectric chip 12 is arranged on the basal surface position near this wedge; Described wedge 112 exposed faces and described mounting plane adapt.
The back side of piezoelectric chip 12 also is provided with a cavity K in described housing 11, and this cavity K all has outlet at housing 11 back sides with the closure of described lead-in wire concentric cable 2; In described cavity K, annotate the filler silica gel that is filled with the ultrasound wave high damping.
Described cavity K opening part overleaf scribbles viscous filler, and posts nameplate on this viscous filler.So that it is as a whole that probe apparatus becomes.
Described housing 11 is provided with cable at the opening part of described lead cable 2 closures and tightens up the hole, and is provided with screw 113 and presses described cable 2 through the described hole that tightens up.
After being provided with more than the process, finish the manufacturing of clipping ultrasonic probe, only need be fixed on the detected fluid pipeline of appointment, connect measurement circuit and get final product work, and the PEI material materials of low resistance are very few, saved valuable material, reduced cost with steel band.
The utility model is low cost of manufacture with respect to the advantage of prior art, and the critical material materials are few, and And it is extremely convenient to install, and is conducive to the application of ultrasonic flowmeter.
