Abstract
The invention provides a water level measurement device for a high-pressure water heater. The water level measurement device is technically characterized by comprising two main pipes and two sampling ports, wherein the two sampling ports are formed vertically in the top and the bottom of a casing of the high-pressure water heater respectively; the two main pipes are arranged vertically in parallel on one side of the casing in the length direction of the casing; each main pipe is connected with the sampling port in the same side through a meter connecting pipe; and multiple pairs of liquid level meter mounting ports are formed in corresponding vertical positions of the two main pipes and connected with liquid level measurement meters through corresponding meter primary valves. Detection of all the liquid level measurement meters can be finished only by forming a pair of sampling ports in the casing, the structure of the water level measurement device on the casing is simplified, the operation difficulty for mounting the water level measurement device on the casing is reduced, proneness to inconsistency of read liquid levels when multiple sampling ports are formed for liquid level selection is avoided, the liquid level reading accuracy is improved, and safety operation of the device can be guaranteed.
Description
Technical field：
The present invention relates to a kind of level measurement device is and in particular to a kind of level measurement device of hot high pressure hydrophone.
Background technology：
In recent years, China's power industry continuous high speed development always, unit grade also gradually rises to from 300MW grade
1000MW grade now, high-pressure heater is as a link of power plant's heat regenerative system, accurate liquid level monitoring, timely action
Protection can ensure the safe operation of high-pressure heater, improves the thermal efficiency of power plant.High-pressure heater is generally according to the need of user
Sample tap to be opened up on housing, due to high-pressure heater run need to arrange multiple water levels, simultaneously need on the spot with teletransmission
Two kinds of pattern liquid level monitorings show, housing equipment typically will open up four pairs of sample taps even more many.Because high-pressure heater sets
Meter pressure is higher, should not on apparatus casing perforate excessive, high-pressure heater limited length simultaneously, the arrangement of adapter also brings along
Certain inconvenience.Meanwhile, carry out liquid level selection using multiple sample taps, the liquid level easily causing different sample taps readings is inconsistent
Phenomenon.
Content of the invention：
The present invention is to overcome the deficiencies in the prior art, there is provided a kind of level measurement device of hot high pressure hydrophone, it can make
Each level gauging instrument reads liquid level by a pair of sample tap, that is, improve the accuracy of level gauging, reduces high pressure again
Water heater arrangement installs the difficulty of construction of liquid level emasuring device.
The level measurement device of the hot high pressure hydrophone of the present invention, the technical scheme being adopted for achieving the above object is：
Including two main pipes and two sample taps, two sample taps are vertically provided at the top of housing and the bottom of hot high pressure hydrophone respectively
Portion, two main pipes pass through instrument connecting tube respectively along the length direction parallel side located at housing up and down of housing, every main pipe
Connect and the sample tap of its homonymy, offer at two main pipes position corresponding up and down some to liquid level instrument installing port, liquid
By corresponding instrument, once door connects each level gauging instrument to position instrument installing port.
As a further improvement on the present invention, every main pipe connects liquid level instrument installing port by reducer tee, its connection
Closely, it is easy for installation and maintenance.
As a further improvement on the present invention, the instrument connecting tube being in housing bottom is provided with sewage draining exit, on sewage draining exit
It is provided with blowoff valve.It is arranged such, can be easy to instrument connecting tube is carried out it is ensured that instrument connecting tube is unobstructed.
As a further improvement on the present invention, every instrument connecting tube is connected with two sample taps by 90 ° of elbow, its
It is completely embedded, be easy for installation and maintenance.
As a further improvement on the present invention, the instrument connecting tube being in housing bottom is provided with a threeway, and three connect
The free end of head is sewage draining exit.It is arranged such, be easily installed enforcement and keep in repair.
The invention has the beneficial effects as follows：The present invention only offers a pair of sampling in the vertical direction of hot high pressure water heater casing
Mouthful, then each sample tap is connected with two main pipes being set in parallel in housing side up and down by instrument connecting tube, and two
Open up at individual main pipe position opposing upper and lower some to liquid level instrument installing port, it is achieved thereby that only passing through to arrange one on housing
Sample tap can be completed with the detection of each level gauging instrument, simplify the structure of liquid level emasuring device on housing, reduce shell
The operation easier of liquid level emasuring device is installed on body, avoids the multiple sample taps of setting simultaneously and carry out easily causing when liquid level is chosen
The inconsistent phenomenon of reading liquid level, improve the accuracy reading liquid level, interior liquid that can exactly to high-pressure heater equipment
Position carries out system monitoring it is ensured that the safe operation of this equipment.
Brief description：
Fig. 1 is the structural representation of the present invention.
Fig. 2 be Fig. 1 along A to schematic diagram.
Specific embodiment：
With reference to Fig. 1 and 2, the level measurement device of this hot high pressure hydrophone, including two main pipes 3 and two sample taps 2, two
