Abstract
The invention discloses an ultrasonic vacuum detecting tube, and particularly relates to the field of vacuum detection. The ultrasonic vacuum detecting tube adopts the structure that an ultrasonic transmitting head and an ultrasonic receiving head are symmetrically distributed in two vertical glass tubes at the waist of a foam tube; the glass tubes are provided with intake and exhaust pipes; during the exhausting process, as the pressure of an vacuumized container is gradually reduced, gas in the container becomes rarefied gradually, the acoustic energy from the ultrasonic transmitting head received by the ultrasonic receiving head is reduced, and the variation of the vacuum degree in the container is reflected; by manufacturing a comparison circuit by comparing the strength of acoustic signals received by a standard vacuum silicon tube with that of acoustic signals received by the ultrasonic vacuum detecting tube, the fact that the pressure of the vacuumized container is displayed according to a vacuum unit can be realized.
Description
Technical field
The present invention relates to a kind of ultrasonic vacuum detector tube, be specifically related to vacuum detecting field.
Background technology
Utilize the principle that sound wave is propagated in media as well, and the impact that the density degree of medium is transmitted sound wave.
Summary of the invention
The invention provides a kind of ultrasonic vacuum detector tube, it is distributed in opposed with Receiver for hyperacoustic emitting head in the vertical glass tube of two of steeping pipe waist, and glass tube is provided with air inlet-outlet pipe; In exhaust process, owing to being declined gradually by the pressure taking out container.Gas in the container gradually thin acoustic wave energy that ultrasound wave Receiver is received from emitting head declines, and reflected thus is the change of vacuum tightness in container; Carry out contrast by the power that the vacuum silicone tube of standard and ultrasonic vacuum detector tube receive acoustic signals and manufacture comparator circuit, can realize being taken out the pressure of container by units of vacuum display.
The present invention is realized by following technical scheme: a kind of vacuum detecting pipe, comprising: bubble pipe, be symmetrically distributed in bubble pipe waist two arms, be distributed in ultrasound wave emitting head in two arms and Receiver; It is characterized in that: described bubble pipe two draws into comb, bubble pipe waist Symmetrical vertical welds two arms; Be respectively fitted with ultrasound wave emitting head and Receiver in two described arms, the lead-in wire of emitting head and Receiver is drawn by tube head and is sealed and prevents gas leak phenomenon; In use, gas outlet connects and is taken out one end described air inlet-outlet pipe, and draft tube connects vacuum pump; The extension line of described emitting head is connected with ultrasonic output circuit; Described Receiver lead-in wire is connected with ultrasound wave receiving circuit.
Good effect of the present invention
1. the characteristic utilizing sound wave can only propagate in medium is simple to carry out vacuum detecting structure, is easy to realize.
2. can directly be connected with vacuum passage, Chinese People's Anti-Japanese Military and Political College's gas impact capacity is strong.
