Description

A kind of turbine drain guide

Technical field

This utility model relates to steam turbine technology field, particularly relates to a kind of turbine drain guide.

Background technology

At present, the steam source that steam turbine is done work using reheated steam as Steam Turbine Through IP Admission, owing to reheated steam mother manages Before drain port, intermediate pressure main stop valve, after drain port, middle pressure pitch, before drain port and low side, drain port is the most individually dredged with one Waterpipe is dredged to condenser by hydrophobic method, owing to reheated steam pressure is higher, in causing drain valve in unit longtime running Leakage, reduces unit economy.

Utility model content

This utility model mainly solves the technical problem in the presence of prior art, thus provide a kind of reduce internal hemorrhage due to trauma, Improve the turbine drain guide of unit economy.

Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:

The turbine drain guide that this utility model provides, it includes turbine body, on described turbine body It is provided with before reheated steam mother's pipe drain port, intermediate pressure main stop valve before drain port, low side drain port after drain port and middle pressure pitch, described Before reheated steam mother's pipe drain port, intermediate pressure main stop valve, before drain port, low side, drain port and the first drain pipe are connected, medium pressure After pitch, drain port and the second drain pipe are connected, and described first, second drain pipe is hydrophobic through the first drain valve and second respectively Valve is connected with condenser, wherein, described first drain pipe is additionally provided with the first isolating valve and the first pneumatic operated valve, and described second dredges The second isolating valve and the second pneumatic operated valve it is additionally provided with on water pipe.

Further, described first drain pipe and the second drain pipe are separately positioned on the both sides of described turbine body.

Further, drain port and low side before described first drain pipe and reheated steam mother's pipe drain port, intermediate pressure main stop valve The removable connection of front drain port, described second drain pipe is connected with after middle pressure pitch, drain port is removable.

Further, the diameter of described first drain pipe is more than the diameter of the second drain pipe.

The beneficial effects of the utility model are: by by drain port before reheated steam mother's pipe drain port, intermediate pressure main stop valve, Before low side, drain port is merged into a road, is connected with condenser through the first drain pipe and the first drain valve, hydrophobic after middle pressure pitch It is connected with condenser by the second drain pipe and the second drain valve, such that it is able to greatly reduce drain valve number, reduces internal hemorrhage due to trauma Generation, improve unit economy, and first, second isolating valve and the assist control of first, second pneumatic operated valve, make drain pipe After road merging, the safety to unit does not impacts, it is ensured that the safety of unit operation.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Fig. 1 is the structural representation of turbine drain guide of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly Define.

Refering to shown in Fig. 1, turbine drain guide of the present utility model, it includes turbine body 1, steam turbine basis Body 1 is provided with before reheated steam mother's pipe drain port 2, intermediate pressure main stop valve and dredges after drain port 4 and middle pressure pitch before drain port 3, low side The mouth of a river 5, before reheated steam mother's pipe drain port 2, intermediate pressure main stop valve, before drain port 3, low side, drain port 4 is connected with the first drain pipe 6 Logical, after middle pressure pitch, drain port 5 is connected with the second drain pipe 7, and first, second drain pipe (6,7) is respectively through the first drain valve 8 It is connected with condenser 10 with the second drain valve 9, wherein, the first drain pipe 6 is additionally provided with the first isolating valve 11 and first pneumatic Valve 12, the second drain pipe 7 is additionally provided with the second isolating valve 13 and the second pneumatic operated valve 14.

This utility model is by by drain port 4 before drain port 3, low side before reheated steam mother's pipe drain port 2, intermediate pressure main stop valve Being merged into a road, be connected with condenser 10 with the first drain valve 8 through the first drain pipe 6, after middle pressure pitch, hydrophobic 5 pass through second Drain pipe 7 is connected with condenser 10 with the second drain valve 9, such that it is able to greatly reduce drain valve number, reduces sending out of internal hemorrhage due to trauma Raw, improve the economy of unit, and first, second isolating valve (11,13) and the auxiliary of first, second pneumatic operated valve (12,14) Controlling, after making drain water piping merge, the safety to unit does not impacts, it is ensured that the safety of unit operation.

It is also preferred that the left arrange to simplify field pipes, the first drain pipe 6 and the second drain pipe 7 are separately positioned on steam turbine The both sides of body 1.Certainly, under specifically used occasion, it is possible to the first drain pipe 6 and the second drain pipe 7 are arranged on steam turbine The same side of body 1.

In this utility model, the first drain pipe 6 and installation and removal of the second drain pipe 7, the first drain pipe 6 for convenience It is connected with before drain port 3 before reheated steam mother's pipe drain port 2, intermediate pressure main stop valve and low side, drain port 4 is removable, the second drain pipe 7 are connected with after middle pressure pitch, drain port 5 is removable.

Unimpeded in order to ensure hydrophobic flowing, the diameter of the first drain pipe 6 is more than the diameter of the second drain pipe 7.

Above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, Any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, Protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
