Embodiment
The invention discloses a kind of drain pipe device, the drain pipe device can evade the erroneous judgement to valves leakage,
So as to reduce unnecessary replacing and maintenance work.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Base
In embodiments of the invention, those of ordinary skill in the art obtained on the premise of creative work is not made it is all its
Its embodiment, belongs to the scope of protection of the invention.
The valve 3 mentioned in background technology is in the case of not interior leakage, original of the valve body temperature always above environment temperature of valve 3
Because as follows：Accompanying drawing 1 is refer to, after after hydrophobic end, valve 3 is closed.Flowed in the bypass of A-B-C-1-D of valve-2-E of valve formation
Lead to main steam.The total drain water piping 300 of electric main steam valve, i.e. main steam in DF segment pipes pass through tube wall, heat-insulation layer and environment
Carry out heat exchange and condense into water, but because DF segment pipes are horizontally disposed, the condensate in DF segment pipes will necessarily flow to D points,
And D points are a rings of the composition of the bypass of main steam line, the condensate band that the main steam of D points is bound to D points are flowed into is flowed through
Walk, after condensate is pulled away, has new main steam and fill into DF segment pipes, DF segment pipes are constantly exchanged with external environment condition again
Heat, will more main devaporation Cheng Shui, condensate constantly flows at D points and to be taken away by the main steam by bypass again, this
Individual process in DF segment pipes life and growth in nature, move in circles.Such pipe valve is laid out the high temperature for causing DF segment pipes to keep constant
State, so as to cause the valve body temperature of valve 3 to remain high, ultimately results in erroneous judgement.
In a specific embodiment of the invention, accompanying drawing 2 is refer to, drain pipe device includes being arranged in parallel in main steam pipe
Drain water piping before drain water piping 200, electric main steam valve after drain water piping 100 and electric main steam valve before electric main steam valve on road
Valve 1 is provided with 100, valve 1 is hydrophobic valve before electric main steam valve.Valve 2 is provided with after electric main steam valve on drain water piping 200,
Valve 2 is hydrophobic valve after electric main steam valve.Also include the output end and electric main steam valve with drain water piping before electric main steam valve 100
On the total drain water piping 300 of electric main steam valve that the output end of drain water piping 200 is connected afterwards, the total drain water piping 300 of electric main steam valve
Valve 3 is provided with, valve 3 is the total hydrophobic valve of electric main steam valve, and output end and the condenser of the total drain water piping 300 of electric main steam valve connect
It is logical.In the present embodiment, valve 3 is connected with valve 2, or valve 3 is connected with valve 1, when valve 3 is closed, valve 2 or valve 1
Also it is accordingly turned off.
In the present embodiment, after hydrophobic end, in shutoff valve 3, valve 2 or valve 1 can be also accordingly turned off.If valve 2 or
Person's valve 1 is closed, then the bypass of the main steam line in drain pipe device is also just cut off, and also just recirculation is not high in bypass
The main steam of warm high pressure, then the condensate in the total drain water piping 300 of electric main steam valve would not also be bypassed in main steam
Take away, the main steam in bypass would not be also filled into the total drain water piping 300 of electric main steam valve, then electric main steam valve is always dredged
The temperature of condensate in waterpipe 300 will lower, and the valve 3 in the total drain water piping 300 of electric main steam valve is in not interior leakage
In the case of, its valve body temperature can be closer to environment temperature.Erroneous judgement is so avoided, unnecessary replacing and maintenance mans are reduced
Make.
In addition, after the bypass of main steam is cut off, the condensate in DF segment pipes would not be taken to by main steam to be transported at a high speed
Turn steam turbine and steam turbine water hammer accident is occurred, so as to improve the security of production.Further, since bypass is cut off,
The not main steam of recirculation HTHP in bypass, main steam also with external environment condition would not carry out heat exchange by bypass, keep away
Exempt from the loss of main steam heat, so as to reach energy-saving purpose.
After bypass is cut off, because main steam pipe channel temp is constant, environment temperature also constant, then in drain pipe
Can there are clear and definite a phase transformation face, wherein phase transformation face in some pipeline section of road above is below the steam of HTHP, phase transformation face
It is condensate.The temperature at phase transformation face place is the temperature of saturated vapour pressure.For same pipe-line system, same main steam temperature and
The environment temperature being more or less the same, phase transformation face is near same position (height) every time.It will be appreciated by those skilled in the art that
, the temperature in phase transformation face is that part more than saturated vapor temperature, phase transformation face is high-temperature high-pressure steam, and temperature all can be very
Height, and part below phase transformation face is condensate, can cool rapidly until close to environment temperature.Therefore, reduce as far as possible hydrophobic
It is exactly the pass for solving power saving that the part full of condensate in the part of high-temperature high-pressure steam, increase pipeline is full of in pipeline
Key.
It refer to the BC sections that drain water piping 100 before accompanying drawing 1, electric main steam valve generally includes vertical AB segment pipes and level
Pipeline.The length of AB segment pipes is shorter under normal circumstances, and the length of BC segment pipes is longer.In the case where bypass is cut off, phase
Change face is typically occurred in BC segment pipes or CD segment pipes, then BC segment pipes are in phase transformation face position, or in phase transformation face
More than, then it is the water vapour part of HTHP present in BC segment pipes.When phase transformation face is located at BC segment pipes, phase transformation face
Length be BC segment pipes horizontal length, now the top half in BC segment pipes be steam, the latter half is condensate.By
It is longer in BC segment pipes, then the water vapour of substantial amounts of HTHP will carry out heat exchange with external environment condition, cause heat to damage
Lose.Therefore, in order to avoid substantial amounts of thermal loss, it is necessary to make phase transformation face appear in vertical AB segment pipes, most directly do
Method is the length of AB sections of extension, but such transformation difficulty is big, cost is high, the time is long, only moves down BC segment pipes
Workload is just very huge, therefore, and U-shaped curved 10 are introduced in a specific embodiment of the invention.It refer to accompanying drawing 3, U-shaped curved 10
To be just vertical, U-shaped curved 10 left port is connected with the output port of AB segment pipes, U-shaped curved 10 right output port and BC segment pipes
Input port is connected.So, the length of AB segment pipes in the vertical direction is extended, and the length of extension is U-shaped curved 10
The length of left side pipe, as long as being of convenient length for U-shaped curved 10 left side pipe, just can form phase transformation face in the pipe of U-shaped curved 10 left side.
In this embodiment, only by set up U-shaped curved 10 can just reach extension AB segment pipe vertical lengths purpose, operation letter
It is single, it is easy to accomplish.
In order to ensure the fastness of U-shaped curved 10 connection, in a specific embodiment of the invention, by U-shaped curved 10 left port
The output port of AB segment pipes is welded in, U-shaped curved 10 right output port is welded in the input port of BC segment pipes.
It is that bypass is cut off by shutoff valve 1 or valve 2 above, still, for some drain pipe devices, electric main steam valve
Preceding hydrophobic valve, i.e. valve 1, and hydrophobic valve after electric main steam valve, i.e. valve 2, can not all be closed, it is meant that A-B-C-valve
Circulation all the time has the main steam of HTHP in the bypass of 1-D-2-E of valve formation, then in this case, how to make DF
Condensate in segment pipe is not taken away by main steam, while avoiding main steam from being added into DF segment pipes, so that DF segment pipes
The temperature of interior condensate lowers, as urgent problem to be solved.
Drain pipe device includes being arranged in parallel the electronic master on main steam line in a specific embodiment of the invention
Before porthole valve is provided with after drain water piping 100 and electric main steam valve on drain water piping 100 before drain water piping 200, electric main steam valve

For the total hydrophobic valve of electric main steam valve, the output end of the total drain water piping 300 of electric main steam valve is connected with condenser.In the present embodiment
In, U-shaped curved 10 are also introduced, this U-shaped curved 10 is connected to the total drain water piping 300 of electric main steam valve, i.e., in DF segment pipes, this is U-shaped
Curved 10 are set close to D points.U-shaped curved 10 setting equivalent to the length for increasing DF sections of in the vertical directions, if U-shaped curved 10
Vertical length is suitable, and phase transformation face, after phase transformation face is formed, the condensation in pipeline after phase transformation face will be formed in U-shaped curved 10
Water is isolated by phase transformation face, and the main steam in will not being bypassed again is taken away, and the temperature of segregate condensate can decline rapidly.This reality
Apply example and the purpose for making the condensate in DF sections cool has been reached in the case where not cutting off bypass, evade the generation of erroneous judgement.
If the space below DF sections is enough, it can be arranged to just vertical by U-shaped curved 10, then U-shaped curved 10 left side
