Abstract
The utility model relates to a pressure matching device for a steam turbine, solving the problem that a heat supply turbine can not operate normally when the steam supply pressure of the turbine is lower than working pressure. The pressure matching device for a steam turbine is composed of a steam chamber, a mixing chamber, a nozzle group, etc. A needle valve group is arranged in the steam chamber. One end of the needle valve group is arranged in a hole of a gland of the steam chamber. The other end of the needle valve group is inserted in a spray hole of a nozzle group fixedly arranged in the steam chamber. The other end of the steam chamber, which is opposite to the gland is fixedly connected to the mixing chamber. The other end of the mixing chamber is connected to a pressure expansion pipe. The utility model which can be arranged on an air inlet pipeline of the turbine and can adopt an air suction pressure matching mode or an air discharge pressure matching mode has the advantages of simple structure and easy realization. The utility model which is suitable for all places using steam turbines also has the effect of energy saving.
Description
The utility model belongs to a kind of adapter, and exactly it is the pressure matcher that a kind of steam turbine uses.
Steam turbine is industrial a kind of machinery commonly used, but such problem often occurs in the use of steam turbine, and promptly the pressure of steam supply of steam turbine is lower than working pressure, and heat supply steam turbine can not normally be moved.Also not seen at present utilizes the steam flow ejector principle to make the report that pressure matcher solves the problems referred to above.
The purpose of this utility model provides a kind of pressure matcher, is mounted to make it can improve the pressure of steam supply of steam turbine effectively in the steam turbine heating system.
The purpose of this utility model is achieved by the following scheme, it is made up of vaporium, mixing chamber, nozzle group etc., it is characterized in that: needle-valve group (5) is housed in the vaporium (1), needle-valve group one end is installed in the hole of gland (6) of vaporium (1), the other end is inserted in the spray-hole (7) of the nozzle group (2) that vaporium (1) internal fixation installs, the fixedly connected mixing chamber of the other end (3) that vaporium (1) is relative with gland (6), mixing chamber (3) the other end is connected with diffuser pipe (4).Can smoke to activity in the spray-hole (7) of the nozzle of needle-valve (8) in vaporium (1) of needle-valve group (5).Nozzle throat spray-hole is the reducing hole.The nozzle group can be a 3-8 nozzle.Vaporium (1) has driving steam port (A) up and down respectively and sucks steam port (B).
The utility model has the advantages that simple in structurely, with low cost, easy to manufacture, but can solve the problem that the steam turbine pressure of steam supply is lower than working pressure preferably, thereby guarantee the normal utilization of steam turbine.The effect that also has energy saving simultaneously.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the utility model system diagram when initial steam pressure mates.
Fig. 4 is the system diagram of the utility model when extraction pressure mates.
Fig. 5 is the system diagram of the utility model when exhaust steam pressure mates.
Y is a pressure matcher among the figure, and Q is a steam turbine.
The utility model is an ejector principle of utilizing steam flow, utilizes the high pressure steam of boiler, and the pressure of steam supply of steam turbine is increased.Vaporium (1), mixing chamber (3) diffuser pipe (5) all weld together behind die forming with steel plate, and nozzle group (2) all gets final product with the processing of general machining method with needle-valve group (5).Get all the whole parts shown in the accompanying drawing ready, assembling gets final product with reference to accompanying drawing.During use according to actual needs, have three kinds of modes available, first kind is pressure matcher to be contained on the steam turbine air inlet pipeline (see accompanying drawing 3), when the pressure of boiler is higher than the initial steam pressure of steam turbine permission, with pressure matcher boiler pressure is reduced, be fit to the admission requirement of steam turbine.It is not to utilize throttling that pressure matcher reduces boiler pressure, but extracts the part low pressure steam out from steam turbine, after two kinds of vapor mixing, has reduced the pressure of Boiler Steam, and this mode has improved generating efficiency than throttling.The second way is that extraction pressure matching way (seeing accompanying drawing 4) is that the extraction pressure of steam turbine uses when being lower than the pressure that the user needs, and by pressure matcher extraction pressure is improved.Without pressure matcher, then steam turbine can not draw gas, and reduces the operational efficiency of steam turbine.The third mode is the exhaust steam pressure matching way, and promptly the exhaust steam pressure of steam turbine is lower than user's the steam pressure of using, without pressure matcher, and then can not be to user's heat supply.Sometimes a plurality of hot users use the steam pressure difference, if satisfy all users' pressure, then the steam discharge of steam turbine will be by the needed pressure of the highest user, and then the generated energy of steam turbine reduces.The part exhaust steam pressure can be raise with pressure matcher, satisfy high pressure user's requirement, steam turbine can be by low back pressure operation, increase generated energy.
