The bullet degree size of spring judges the aperture of live vent valves.
Further, data processor presets the SVEL of no material in pipeline is detected, specially in drain valve
Acoustic receiver is installed in upper end, and sound transmitter is being installed apart from the centimeters of acoustic receiver 50；And with calculating formula v=s/t
The speed that sound wave is propagated in the duct can be obtained, wherein v is the speed that sound wave is propagated in the duct, and s is sound transmitter and sound wave
50 centimetres of the length of receiver, t be sound transmitter transmitting sound wave to the time of acoustic receiver, pass through data processor meter
Calculate the SVEL for just drawing default blank pipe.
Further, data processor detects detection pipeline internal memory in material, is opened with reference to scene discharge hand valve hand wheel
Degree judges that drain valve with the presence or absence of blocking, leads to not discharge material；Specially live hand valve opens small guide vane, at handwheel
Sensing spring flick outward, sound transmitter starts toward pipeline internal emission sound wave, apart from 50 centimetres of sound of sound transmitter
Ripple receiver receives sound wave, and data processor can obtain the speed that sound wave propagates in the duct according to calculating formula v=s/t, and wherein v is
The speed that sound wave is propagated in the duct, s are 50 centimetres of the length of sound transmitter and acoustic receiver, and t sends out for sound transmitter
The sound wave penetrated just draws the SVEL of the detection pipeline to the time of acoustic receiver by calculating；Detection calculates immediately
SVEL contrasts with default blank pipe SVEL, more than default blank pipe SVEL, illustrates material in pipeline be present, ties
Live hand valve opening is closed, judges valve blockage.
Beneficial effects of the present invention：
The present invention judges that discharge tube whether there is material, with reference to discharge valve opening, judges to arrange by the sound speed detection in pipeline
Put whether valve blocks.Give site operation people one warning message, discharged by safer technology.

Embodiment
Below with reference to the embodiment of the brief description of the drawings present invention.
A kind of judgement chemical industry scene drain valve block system based on sound speed detection, it is characterised in that sent including sound wave
Device, acoustic receiver, data processor；The sound transmitter is installed on depot siding before vent valves, toward pipeline inside send
Sound wave, the sound wave recipient are installed on detection pipe line back end, and sound wave is sent to sound wave receiving by the absorption of material in pipeline
Device, detected by data processor for analysis, whether there is material before drain valve, judge whether valve blocks.Sound transmitter is
Telescopic pipeline chuck, its chuck is rounded, and one pinger of every 90 degree of settings, quantity is 4；The acoustic emission
The frequency of sound wave of device transmitting is 500 hertz.Sound wave recipient be used for receive sound transmitter transmitting acoustic signals, be installed on away from
From the position in the live vent valves direction of the centimeters of sound transmitter 50.Data processor is also attached to live vent valves
Measuring opening, specially vent valves handwheel installs induction type spring with sealing surface interval at the scene；When live vent valves
When handwheel is opened, induction type spring will be expanded according to elastic force, and when live vent valves handwheel is closed, induction type spring will be received
Contracting；The data processor judges the aperture of live vent valves according to the bullet degree size of induction type spring.Data processor exists
