Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of ultrasonic flowmeter reflection
Device, the technical problem to be solved by the utility model is to how to improve the convenience that ultrasound reflector dismounts on shell.
The purpose of this utility model can be realized by the following technical scheme: a kind of Reflecting device of ultrasonic flowmeter, including
Shell and setting in a tubular form all has convex in intracorporal two ultrasound reflectors of shell, the outer peripheral surface at the shell both ends
Platform, two boss are symmetrical arranged, which is characterized in that it is intracorporal logical that the axial direction on the outer end face of the boss along boss offers shell
Hole offers step surface on the inner sidewall of the through-hole, and the ultrasound reflector is plugged in through-hole and ultrasound reflector
Outer peripheral surface on there is the cyclic convex edge that is resisted against on step surface, be provided between the upper surface and step surface of the cyclic convex edge
Sealing ring, the outer end of the through-hole are bolted with lock sleeve, and one end of the lock sleeve is resisted against the lower end surface of ultrasound reflector
On.
When installation, ultrasound reflector is inserted into corresponding through-hole, when the upper surface of cyclic convex edge is resisted against step
When on face, i.e. expression ultrasound reflector is inserted in place, and then lock sleeve is screwed on through-hole, lock sleeve is screwed and to lock
It covers mobile to ultrasound reflector direction until one end of lock sleeve is resisted against in ultrasound reflector, so that sealing ring is pressed on
On step surface, sealing effect is improved, the intracorporal fluid of shell is avoided to leak out；It needs replacing ultrasound reflector or disassembly ultrasonic wave is anti-
When beam, lock sleeve is screwed out from through-hole, ultrasound reflector can be unloaded from shell.The structure can be directly in shell
Upper dismounting ultrasound reflector substantially increases the convenience that ultrasound reflector dismounts on shell.
In a kind of above-mentioned Reflecting device of ultrasonic flowmeter, the outer peripheral surface on the ultrasound reflector top and through-hole
More than two sealing rings are provided between inner sidewall from top to bottom.
In a kind of above-mentioned Reflecting device of ultrasonic flowmeter, the lower end surface of the lock sleeve and ultrasound reflector it
Between be provided with spring, the spring is in compressive state.Spring is in and is compressed after lock sleeve is resisted against in ultrasound reflector
There is upward active force to act in ultrasound reflector for state, spring, further increase the upper of step surface and cyclic convex edge
Leakproofness between surface.
In a kind of above-mentioned Reflecting device of ultrasonic flowmeter, the downward convex in middle part of the ultrasound reflector lower end surface
At positioning protrusion, there is the locating slot being oppositely arranged with positioning protrusion on the lock sleeve, one end of the spring is socketed in fixed
Position protrusion is upper, the other end extends in locating slot.
Compared with prior art, the Reflecting device of ultrasonic flowmeter of the utility model has the advantage that the structure can be straight
It connects and dismounts ultrasound reflector on shell, substantially increase the convenience that ultrasound reflector dismounts on shell.
