Description
Technical field
The utility model relates to a kind of breather line, especially a kind of steam turbine breather line.
Background technique
Steam turbine is the external combustion rotary machine that steam thermal energy can be converted into mechanical work, after entering steam turbine, successively through nozzle and the movable vane of a series of loop configurations, is the mechanical energy that turbine rotor rotates by the thermal energy of steam from the steam of boiler.Steam turbine works usually under High Temperature High Pressure and high-revolving condition, is a kind of comparatively accurate heavy machinery.
The breather line of steam turbine is for being passed in steam turbine high-pressure cylinder, intermediate pressure cylinder and low pressure (LP) cylinder by the water vapor in boiler, owing to passing into, vapor (steam) temperature in pipeline is high, pressure is large, so the breather line of steam turbine is easy to produce oxidation, the problems such as distortion, and be also unfavorable for tightness under the environmental conditions of High Temperature High Pressure.
Summary of the invention
The technical problem that the utility model solves there is provided a kind of steam turbine breather line, solve steam turbine breather line in prior art working life short, be difficult to keep in repair, the defect of poor air-tightness.
Technological scheme
A kind of steam turbine breather line, comprise high pressure pipe line, middle pressure pipeline and low pressure pipeline, described high pressure pipe line one end is steam inlet end, and the sidewall in the middle part of described high pressure pipe line has high-pressure cylinder steam inlet, is provided with high pressure valve in described pipeline intersection; The described high pressure pipe line the other end is connected with middle pressure pipeline, and pipeline junction is fixed by clamp device;
Sidewall in the middle part of described middle pressure pipeline has intermediate pressure cylinder steam inlet, and described pipeline intersection is provided with Middle pressure valve; The described middle pressure pipeline the other end is connected with low pressure pipeline, and pipeline junction is fixed by clamp device;
Be connected with low pressure cylinder after described low pressure pipeline vertical turn.
The valve of described pipeline intersection is a kind of oscillation plate type valve.
Beneficial effect
Steam turbine breather line described in the utility model is spliced by multistage pipeline, only needs damage section to take off to keep in repair, so easy to maintenance during maintenance.
Have the trend of twice Valve controlling steam in the utility model, per pass valve all has seal ring to wrap up, and air-tightness is good.
Accompanying drawing explanation
Fig. 1 is steam turbine breather line described in the utility model.
Wherein: 1-high pressure pipe line, pressure pipeline in 2-, 3-low pressure pipeline, 4-high pressure valve, 5-high-pressure cylinder steam inlet, 6-Middle pressure valve, 7-intermediate pressure cylinder steam inlet, 8-low pressure (LP) cylinder steam inlet, 9-clamp device, 10-steam inlet.
Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
The utility model relates to a kind of steam turbine breather line, comprise high pressure pipe line 1, middle pressure pipeline 2 and low pressure pipeline 3, described high pressure pipe line 1 one end is steam inlet 10 end, and the sidewall in the middle part of described high pressure pipe line 1 has high-pressure cylinder steam inlet 5, is provided with high pressure valve 4 in described pipeline intersection; Described high pressure pipe line 1 the other end is connected with middle pressure pipeline 2, and pipeline junction is fixed by clamp device 9;
Sidewall in the middle part of described middle pressure pipeline 2 has intermediate pressure cylinder steam inlet 7, and described pipeline intersection is provided with Middle pressure valve 6; Described middle pressure pipeline 2 the other end is connected with low pressure pipeline 3, and pipeline junction is fixed by clamp device 9;
Be connected with low pressure cylinder after described low pressure pipeline 3 vertical turn.
The valve used in the utility model falls steam in rear pipeline and can not enter in cylinder body for a kind of oscillation plate type valve, wobble plate, otherwise if wobble plate is holded up, so steam then can enter in cylinder body, can not enter next segment pipe by flow forward.
Steam turbine breather line described in the utility model is applicable to the steam turbine of three-port type completely, steam enters from steam inlet and enters high-pressure cylinder, intermediate pressure cylinder and low pressure (LP) cylinder respectively afterwards, the temperature and pressure entering each cylinder body is different, the gas entered in cylinder body drives blade rotation, is mechanical energy by thermal energy.
In sum, to be everyly spliced by three segment pipes, to be applicable to the steam turbine breather line of three-port type completely all within protection domain of the present utility model.
