The content of the invention
For overcome the deficiencies in the prior art, the invention provides a kind of small-bore Ultrasonic water meter, the small-bore ultrasonic water
There is table good airproof performance, ultrasonic probe not to be contacted with fluid media (medium), and measurement accuracy is high.
To achieve these goals, the technical solution adopted by the present invention is：A kind of small-bore Ultrasonic water meter, including table cover,
Watchcase, it is anti-that watchcase includes upper shell, lower casing and the ultrasonic flow rate reflection unit being installed between upper and lower shell, ultrasonic flow rate
Injection device includes reflection housing, and reflection housing is provided with fluid passage, and ultrasonic flow rate reflection unit includes ultrasonic probe and reflection
Body, it is characterised in that：The ultrasonic probe is embedded at fluid passage in one side side wall of upper shell and through sealant pouring and sealing,
The reflector is axially mounted to be fixed in fluid passage at the port of fluid passage and through support frame along fluid passage.
Further, the reflector is suspended in center at the port of fluid passage, and reflector outer wall is consolidated by X-type support chip
Due in the port of fluid passage, X-type support chip and fluid passage inwall integrally connected.
Further, the reflector with rectifier, and fluid passage two are mounted at the port of the fluid passage both sides
Corresponding ultrasonic probe is mounted in the side wall at end.
Further, the flow channel cross-sections are rectangular configuration, are round transition at rectangle knuckle, the side of rectangle two
For convex structure.
Using such scheme, the present invention is that ultrasonic probe is directly installed on reflection housing, is fixed, surpassed with fluid sealant
What sonic probe was not communicated with fluid passage, therefore, ultrasonic probe does not contact with fluid media (medium), and runner is smooth, so ultrasonic
Bubble will not be produced at ripple probe, measurement accuracy can be improved；And seal leakage problem is also not present at sensor.Due to super
Sonic probe forms an overall structure by encapsulating and reflection housing, realizes ultrasonic probe with reflecting the integrated knot of housing
Structure, its assembling are more compact；It is equal to improving measurement accuracy and stability and fluid passage uses the structure of rectangular strap circular arc
It is beneficial；Because water (flow) direction is consistent with reflected line direction in fluid passage, drift can be reduced, improve accuracy, also,
Reflector uses the structure that rectifier and reflector are combined as a whole, and it requires very low to front and rear straight length, to measuring environment
It is required that it is low, have and preferably use adaptability.
The invention will be further described below in conjunction with the accompanying drawings.

Embodiment
The specific embodiment of the present invention is small-bore Ultrasonic water meter as illustrated in figs. 2 through 8, including table cover 1, watchcase 2, watchcase 2 wrap
Shell 21, lower casing 23 and the ultrasonic flow rate reflection unit 3 being installed between upper and lower shell 23 are included, is installed in upper shell 21
There is gauge outfit box 211, battery case 212 and battery 213, the upper correspondence of lower casing 23 are installed in gauge outfit box 211, the side wall of lower casing 23 is set
There is mounting flange 221, positioning screw 222 is threaded with mounting flange 221, after positioning screw 222 passes through mounting flange 221
It is fixedly connected with upper shell 21, above-mentioned gauge outfit box 211 also isolates sealed volume close to one end of table cover 1 and shown for installing mainboard
Show plate 4, the mainboard display board 4 electrically connects with battery 213, and ultrasonic flow rate reflection unit 3 includes reflection housing 31, reflects housing 31
Provided with fluid passage 311, ultrasonic flow rate reflection unit 3 includes ultrasonic probe 32 and reflector 33, and ultrasonic probe 32 is embedded
Sealed in fluid passage 311 in one side side wall of upper shell 21 and through pouring into fluid sealant 34, reflector 33 is along fluid passage
311 are axially mounted to be fixed in fluid passage 311 at the port 311b of fluid passage 311 and through support frame.
Reflector 33 is suspended in center at the port 311b of fluid passage 311, and the outer wall of reflector 33 is solid by X-type support chip 34
Due in the port 311b of fluid passage 311, X-type support chip 34 and the inwall integrally connected of fluid passage 311.
The reflector 33 with rectifier, and the both ends of fluid passage 311 are mounted at the both sides port 311b of fluid passage 311
Side wall in be mounted on corresponding ultrasonic probe 32.
The rectangular cross-section structure of fluid passage 311, it is round transition at rectangle knuckle, the side of rectangle two is convex
311a structures.
The present invention is that ultrasonic probe 32 is directly installed on reflection housing 31, is fixed with fluid sealant 34, ultrasonic wave is visited
First 32 are not communicated with fluid passage 311, and therefore, ultrasonic probe 32 does not contact with fluid media (medium), and runner is smooth, so ultrasonic
Bubble will not be produced at ripple probe 32, measurement accuracy can be improved；And seal leakage problem is also not present at sensor.Due to
Ultrasonic probe 32 forms an overall structure by encapsulating and reflection housing 31, realizes ultrasonic probe 32 and reflection housing 31
