Description
Technical Field
The utility model relates to an ultrasonic device especially indicates an ultrasonic sound pipe.
Background
The ultrasonic gas meter is a device for measuring gas flow by using the speed change of ultrasonic waves in fluid, and the ultrasonic gas meter brings great difficulty to the measurement of the ultrasonic waves because the propagation speed of the ultrasonic waves is fast and the gas has the characteristics of non-uniform density and non-uniform speed. How to enable the gas to uniformly pass through the ultrasonic rectangular flow channel with uniform density and uniform speed is a key for improving the measurement precision, the ultrasonic stroke of the traditional ultrasonic gas meter is V-shaped, and the projection distance of the ultrasonic is short; and the longer the projection stroke of the ultrasonic wave in the flow channel cavity is, the higher the metering accuracy is.
SUMMERY OF THE UTILITY MODEL
The utility model provides an ultrasonic sound pipe which solves the problems existing in the prior art.
The technical scheme of the utility model is realized like this:
an ultrasound channel tube comprising: the square and round gas flow channel comprises a middle rectangular flow channel and circular tube heads at two ends, wherein the circular tube heads are outwards opened and are provided with probe positioning grooves, the probe positioning grooves are installed in the circular tube heads through three clips, and the ultrasonic probes are arranged in the probe positioning grooves.
Furthermore, the two ultrasonic probes in the circular tube head correspond to each other and are positioned on the central axis of the rectangular flow channel.
And furthermore, a probe fixing cap is also arranged at the outer opening of the probe positioning groove, and the ultrasonic probe is arranged on the inner ring of the probe rubber ring and is fixed in the probe positioning groove.
Further, the upper end of the clamp is a fixing cap, and the fixing cap is clamped on the upper portion of the probe rubber ring.
The utility model has the advantages that: the device can realize the maximum flow speed time difference measured by the shortest distance, can improve the received signal strength, and has the advantages of high sensitivity and low attenuation effect.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 to 5, an ultrasonic sound channel tube includes: the square and round gas flow channel comprises a middle rectangular flow channel 1 and circular tube heads 2 at two ends, wherein the circular tube heads 2 are outwards opened, two mounting brackets 3 are further arranged on one side of each circular tube head 2, a probe positioning groove 4 is formed in each circular tube head 2, the probe positioning groove 4 is installed in each circular tube head 2 through three clips 5, and an ultrasonic probe 9 is arranged in each probe positioning groove 4.
Three bayonets 6 have been seted up on the outer wall of circular tube head 2, and checkpost 5 card is in bayonet 6, and 5 opposite sides of checkpost are fixed on the cell wall of probe positioning groove 4, and the upper end of checkpost 5 is locking cap 7, and locking cap 7 card is on the upper portion of probe locking cap 8.
A probe fixing cap 8 is further arranged at the outer opening of the probe positioning groove 4, and the ultrasonic probe 9 is mounted on the inner ring of the probe fixing cap 8 and is fixed in the probe positioning groove 4.
The actual propagation speed of the sound wave in the fluid is composed of the propagation speed of the sound wave in the static state of the medium and the components of the axial average flow speed of the fluid in the propagation direction of the sound wave.
Two mounting brackets 3 are provided on each circular tube head 2, a circuit board (not shown) is mounted on the mounting brackets 3 and electrically connected to the two ultrasonic probes 9, the received sound wave signal is converted into a visible signal by the circuit board, and then the flow rate is calculated by calculating the difference between the speed at which the gas flows downstream and the speed at which the gas flows upstream.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
