The utility model has the following contents:
the utility model aims at providing a power plant's oxygen-eliminating device water level measurement station sample anti-clogging device.
The above purpose is realized by the following technical scheme:
the utility model provides a power plant's oxygen-eliminating device water level measurement station sample anti-clogging device which constitutes and includes: the anti-blocking device is provided with a straight pipe, the straight pipe is installed at an opening of a measuring point sampling pipe at the bottom of a deaerator of a power plant, the upper end of the straight pipe is connected with a dustproof pipe, an exhaust float valve is installed at the top of the upper portion of the dustproof pipe, the dustproof pipe is connected with an anti-surge pipe, and the measuring point sampling pipe is connected with a measuring point.
A sampling anti-blocking device for a water level measuring point of a deaerator in a power plant comprises an exhaust float valve and a valve body, wherein the exhaust float valve comprises: the valve body is of a thick-wall tubular structure, a bevel groove is formed in the sharp corner of the upper end of the valve body, a smooth spherical surface is arranged at the lower end of the valve body, the spherical surface is attached to a closed spherical crown, an exhaust sliding pipe is arranged at the upper end of the spherical crown, side grooves are formed in the upper end and the lower end of the exhaust sliding pipe respectively, the upper end of the exhaust sliding pipe is connected with a ring cap, a floating ball is arranged at the upper end of the ring cap, the aperture of an inner hole of the straight pipe is 10-50mm larger than that of the sampling pipe, the distance between the lower end of the anti-surge pipe and the bottom plane of the deaerator is 100-200mm, the aperture of the anti-surge pipe is 1-2 times that of the sampling pipe, and the aperture of the anti-surge pipe is 1.5-3 times that of.
The utility model has the advantages that:
1. the utility model discloses a structure have the straight tube, the straight tube bottom constitute the protection cofferdam in the oxygen-eliminating device of power plant, have and block heavier deposit and get into the sampling tube in, therefore effectively prevented the sampling tube take place to block up.
The utility model discloses a U type dustproof pipe has been connected to the straight tube upper end, and this structure can prevent that the cubic precipitate of accidental from getting into the zone of protection along the straight tube hole in, thereby further strengthened the utility model discloses a protective action.
The utility model discloses a structure has prevents the surge pipe power plant's oxygen-eliminating device first water injection during, because of the precipitate that the water injection disturbance produced a large amount of suspensions, at the surface of water lift in-process, make the suspended solid because of the injection of water can't deposit because of the surge, the utility model discloses a prevent surge pipe utensil has less bore, and less bore is favorable to the vibration energy of the interior water of rapid attenuation pipe, therefore this structure has the effect that can make water static in shorter time to make the aquatic precipitate appear in intraductal, thereby effectively prevent the precipitate jam the sampling tube.
The utility model discloses a dustproof pipe top has floater discharge valve, discharge valve structure can guarantee that this device can get rid of residual gas with the complete evacuation of intraductal air when filling water, makes level sensor obtain true data.
The utility model discloses all adopt welded structure, simple structure easily construction operation has extremely low use cost, is fit for promoting in the protection of power plant's water oxygen-eliminating device water level measurement station is reformed transform.
The utility model discloses a three-section structure is favorable to adjusting the protection pipe diameter, both can use the same pipe diameter, also can use different pipe diameters to reach better protecting effect.
