Brief description of the drawings
Fig. 1 is a kind of structural representation of oxygen-eliminating device self-water replenishing overflow water seal arrangement of the present invention.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of described oxygen-eliminating device self-water replenishing overflow water seal arrangement, including U-shaped relief sewer, filling pipe
2 and the water sealed tank 3 that is arranged at outside oxygen-eliminating device 2, the U-shaped relief sewer by water inlet segment 4 and water outlet pipeline section 41, with
And the connection pipeline section 42 of connection water inlet segment 4 and water outlet pipeline section 41 is constituted, the water inlet segment 4 of U-shaped relief sewer is extended upwardly into
Inside oxygen-eliminating device 2 and water inlet segment 4 water inlet pipe mouth be located at oxygen-eliminating device 2 highest safety level a, U-shaped relief sewer
Water outlet pipeline section 41 is connected with inserting the drainpipe 5 of water sealed tank 3, the open top of the water sealed tank 3 and in water sealed tank 3
Overfall 6 is provided with the wall of side, the water inlet end of the filling pipe 1 is stretched into inside oxygen-eliminating device 2 and its water inlet pipe mouth is less than deoxygenation
The normal work water level b of device 2, U-shaped relief sewer is stretched into the water side of the filling pipe 1；In the present embodiment, filling pipe 1
Water side stretch into the water outlet pipeline section 41 of U-shaped relief sewer, so when oxygen device inner overpressure breaks through U-shaped relief sewer
During water seal, it can be made inside U-shaped relief sewer quickly by stretching into the filling pipe 1 of water outlet pipeline section 41 of U-shaped relief sewer
Ground re-forms water seal；In the present embodiment, the effluent pipe mouth of the water side of filling pipe 1 is less than formation water in U-shaped relief sewer
The liquid level c of water in Feng Shiqi water inlet segments 4, so when oxygen device inner overpressure breaks through the water seal of U-shaped relief sewer, passes through
Stretching into the filling pipe 1 of the water outlet pipeline section 41 of U-shaped relief sewer can make to re-form more quickly inside U-shaped relief sewer
Water seal；In the present embodiment, the overfall of water sealed tank 3 is located at the position with the normal work water level flush of oxygen-eliminating device, so
The water seal effect of water sealed tank can further be improved；In the present embodiment, the water inlet end of the filling pipe 1 in bore from bottom to top
The bell shape gradually increased is set, and can so increase the water inlet area of filling pipe, so when oxygen device inner overpressure is rushed
During the water seal of broken U-shaped relief sewer, by stretching into the filling pipe 1 of water outlet pipeline section 41 of U-shaped relief sewer U-shaped can be made to overflow
Water seal is re-formed more quickly inside stream drainpipe；
The operation principle of the present invention is as follows：
When liquid level inside oxygen-eliminating device 2 is higher than highest safety level, unnecessary water can enter U-shaped relief sewer, then through row
Water pipe 5 enters water sealed tank 3, then is discharged from the overfall 6 of water sealed tank 3, so as to realize overflow discharge；
When oxygen-eliminating device internal pressure is exceeded service pressure when the steam in oxygen-eliminating device is excessive, unnecessary steam can be rushed first
Break the water seal in U-shaped relief sewer and enter water sealed tank 3, the water seal of water sealed tank 3 is then broken through again and air is discharged into, makes deoxygenation
Device pressure release；Because the water inlet pipe mouth of filling pipe 1 is less than the normal work water level b of oxygen-eliminating device 2, so the now water in oxygen-eliminating device 2
U-shaped relief sewer constantly can be flowed into from filling pipe 1, re-establish the water seal of U-shaped relief sewer, and treat that U-shaped overflow is arranged
After water seal in water pipe is rebuild, the water in U-shaped relief sewer can constantly fill into water sealed tank 3, re-establish the water of water sealed tank 3
Envelope.
It is an advantage of the invention that：（1）Moisturizing adjusting means and other external water sources need not be equipped with again, greatly reduce enterprise
Industry use cost；（2）It is simple in construction, it can be achieved with automatic water supplement without artificial operation and re-establish water seal, using more convenient.
