Description
Technical Field
The utility model belongs to the liquid level measurement field, concretely relates to low pressure feed water heater's liquid level measurement device.
Background
The fault statistics of each part of the existing low-pressure heater is carried out, and the fault rate of the remote liquid level meter is the highest, and the main reason is that a large amount of impurities are accumulated in an inlet pipeline of the remote liquid level meter. Such impurity is piled up and can directly arouse the liquid level indication inaccuracy of teletransmission level gauge, and then influences the normal production of whole condensate system, consequently needs to improve the reliability of this liquid level teletransmission device to case unit long period safety and stability's operation.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem of piling up of impurity, the utility model discloses install sediment pipe additional in inlet pipeline department to the size of sediment pipe is greater than the inlet pipeline, reduces the influence of sediment to the liquid level measurement result.
The utility model discloses a realize through following technical scheme: a liquid level measuring device for a low pressure heater, comprising: the device comprises a low-pressure heater, a liquid level meter inlet pipe, a sediment pipe, a liquid level measuring pipe and a remote transmission liquid level meter;
one end of the liquid level meter inlet pipe is connected with the bottom of the low-pressure heater, the other end of the liquid level meter pipe inlet pipe is connected with the first end of the slag settling pipe, the second end of the slag settling pipe is an open end and is provided with an end cover, and the end cover is connected with the open end through a bolt;
one end of the liquid level measuring pipe is connected with the middle part of the slag settling pipe, and the other end of the liquid level measuring pipe is connected with the remote transmission liquid level meter.
Further, the diameter of the slag settling pipe is larger than that of the liquid level meter inlet pipe. The diameter of the sediment pipe is 2-4 times of the diameter of the liquid level meter inlet pipe, and the design can increase the storage amount of the sediment pipe to sediment and reduce the influence of the sediment on the measurement accuracy of the remote-transmission liquid level meter.
Furthermore, a sealing device is arranged at the joint of the end cover and the opening end of the slag settling pipe, so that more corrosion at the joint of the end port and the end cover caused by liquid seepage is avoided.
Furthermore, the sediment pipe is obtuse angle structure, conveniently clears up the intraductal accumulational impurity of sediment.
Further, the device also comprises a sediment storage box. This receiver is placed under the sediment pipe when the maintenance clearance for accomodate impurity.
The utility model has the advantages that: the utility model discloses an increase and to clear up formula sediment pipeline to a plurality of sediment pipelines set up side by side, have reduced the measurement inaccuracy that the teletransmission level gauge leads to because of accumulational debris in the pipeline, have consequently increased the reliability when low pressure feed water heater moves.

In the figure: the device comprises a low-pressure heater 1, a liquid level meter inlet pipe 2, a sediment pipe 3, a liquid level measuring pipe 4, a remote liquid level meter 5 and an end cover 6.
Detailed Description
As shown in fig. 1-3: a liquid level measuring device of a low pressure heater 1 is characterized by comprising: the device comprises a low-pressure heater 1, a liquid level meter inlet pipe 2, a sediment pipe 3, a liquid level measuring pipe 4 and a remote transmission liquid level meter 5;
one end of the liquid level meter inlet pipe 2 is connected with the bottom of the low-pressure heater 1, the other end of the liquid level meter inlet pipe 2 is connected with the first end of the slag settling pipe 3, the second end of the slag settling pipe 3 is an open end and is provided with an end cover 6, and the end cover 6 is connected with the open end through a bolt;
one end of the liquid level measuring tube 4 is connected with the middle part of the sediment tube 3, and the other end of the liquid level measuring tube 4 is connected with the remote transmission liquid level meter 5.
The diameter of the slag settling pipe 3 is larger than that of the liquid level meter inlet pipe 2. The diameter of the sediment pipe 3 is 2-4 times of the diameter of the liquid level meter inlet pipe 2, and the design can increase the storage amount of the sediment pipe 3 to sediment and reduce the influence of the sediment on the measurement accuracy of the remote-transmission liquid level meter 5.
The connecting part of the end cover 6 and the opening end of the sediment pipe 3 is provided with a sealing device, so that more rust at the connecting part of the end port and the end cover 6 caused by liquid seepage is avoided.
The sediment pipe 3 is of an obtuse angle structure, and impurities accumulated in the sediment pipe 3 can be conveniently cleaned.
The device also comprises a sediment storage box. This receiver is placed under sediment pipe 3 when the maintenance clearance for accomodate impurity.
The utility model discloses a use does, and teletransmission level gauge 5 overhauls after predetermined live time, lifts end cover 6 off during the maintenance, clears up the accumulational debris in end cover 6 and the sediment pipe 3 to the sediment receiver. After cleaning, the end cover 6 can be installed to be put into normal production again.
