Description
Technical field
Visited the invention belongs to liquid automatic measurement technology field, more particularly to a kind of pipeline with ultrasonic flowmeter
The online assembly and disassembly methods of head.
Background technology
The measure of water equipment of certain Iron Works high pressure water system uses plug-in type ultrasonic flowmeter, should
The probe of ultrasonic flowmeter include signal cable, outlet nozzle nut, locking nut, attaching nut, ball valve,
Connecting seat, probe rod, sound wedge surface, probe are fixed in high-pressure water pipe by being connected to, probe rod rear end
Sound wedge surface is stretched into high-pressure water pipe.
During blast fumance, the hydraulic pressure in high-pressure water pipe can not cut off the water for a long time up to 1MPa or so, otherwise right
All there is the hidden danger burnt out in blast furnace, hot-blast stove main equipment.In the case where that can not cut off the water, work as tip damage
Or when breaking down, because hydraulic pressure is too high, it is impossible to extract probe, therefore can not be cleaned or be changed.
Especially when scene adds decoction to water pot, a large amount of bubbles can be produced in high-pressure water pipe, are caused to probe measurement
Extreme influence, causes measuring system misalignment, has a strong impact on monitoring of the scene to pipeline water.
The content of the invention
The purpose of the present invention aims at online do not cut off the water and carries out the dismounting of probe of ultrasonic flowmeter, so as to protect
Card failure is handled in time, it is to avoid production loss.
Therefore, the technical solution that the present invention is taken is：
A kind of probe of ultrasonic flowmeter assembly and disassembly methods, it is concretely comprised the following steps：
(1) prepared by instrument：Including clamp, screw rod and location nut；The clamp is a stripe board, bar shaped
Equidistantly three slots are provided with the wide face in plate side；The screw rod and 2 and screw rod of 2 full screw threads are prepared simultaneously
The location nut of cooperation；
(2) 2 screw rods with location nut are respectively welded to the high pressure of probe of ultrasonic flowmeter both sides
On water pipe；The notch of three slots of clamp is installed on probe and both sides screw rod respectively down again, its middle position
It is stuck in middle slot between the outlet nozzle nut of probe and locking nut；And distinguish 2 location nuts
It is connected to fixing chuck plate on 2 screw rods；
(3) during cleaning probe, rotate counterclockwise is unclamped after location nut, removes clamp；
(4) ball valve on probe is opened, and unclamps the locking nut of probe, the high pressure in high-pressure water pipe is utilized
Water carrys out probe rod ejection；
(5) ball valve closed on probe, the attaching nut for unclamping probe removes probe sensor and cleaned
Or change；
(6) probe sensor cleaning or change after the completion of, then by step (2) method by clamp return be attached to
On probe and both sides screw rod, the ball valve on probe is then opened；
(7) location nut on the screw rod of both sides is gradually screwed with spanner, location nut will be popped one's head in by clamp and be passed
Sensor is gradually advanced into operating position；
(8) tighten successively after attaching nut and locking nut, that is, complete probe of ultrasonic flowmeter dismounting and clear
Wash journey.
The clamp is a 280~320mm of length, wide 28~35mm, 8~12mm of thickness steel plate.
The spiro rod length 80~110mm longer than probe of ultrasonic flowmeter length.
Beneficial effects of the present invention are：
Do not cut off the water present invention can be implemented in line and carry out the dismounting of probe of ultrasonic flowmeter, clean and change, from
And blast furnace staying accident is avoided, failure is handled in time, shorten the accident treatment time, reduce accident and damage
Lose, it is ensured that production is smoothed out.
Brief description of the drawings
Fig. 1 is probe of ultrasonic flowmeter structure and dismounting schematic diagram.
In figure：Signal cable 1, outlet nozzle nut 2, locking nut 3, attaching nut 4, ball valve 5, connection
