Description
Technical field
The utility model relates to a kind of components of steam turbine, especially a kind of steam valve.
Background technique
Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be make the media flow in pipe arrangement and equipment or stop and the device of its flow can be controlled.
The valve used in the utility model is a kind of ball valve, and ball valve is a kind of common valve, has the advantage of wear-resisting, good seal performance and long service life.Traditional valve version can realize the control for fluid, but real-time monitoring can not be carried out by convection cell, and for the valve be applied in steam turbine, the fluid that valve will control is the steam of High Temperature High Pressure, and the stability for valve working it is also proposed higher requirement.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of steam valve for steam turbine, solves valve working instability, steam condition in prior art and can not get feedback, can not adjust the defect of valve in time.
Technological scheme
A kind of steam valve for steam turbine, comprises steam reception unit, valve control device, valve, lockable mechanism and steam monitoring device;
Together with described steam reception unit is fastened by bolts with valve, described valve internal is a cavity, described cavity sidewalls has a gas channel, the other end of described passage is connected with steam monitoring device, described valve is by a Control Shaft control valve, described Control Shaft is connected with a rotatable handle, and the middle part of described Control Shaft is provided with a lockable mechanism, and described lockable mechanism controlling rod stretches out valve body;
Thermometer and gas manometer is provided with in described steam monitoring device.
Described steam valve for steam turbine is a kind of ball valve.
The ingress of described steam reception unit is provided with seal ring, and described seal ring has three roads.
Beneficial effect
Steam valve for steam turbine described in the utility model is the Special valve be specifically applied in steam turbine, and its material is high temperature resistant, high pressure resistant material, working stability.
The steam that steam valve for steam turbine described in the utility model receives has sub-fraction for status monitoring, mainly reflects the temperature and pressure of steam, to adjust valve at any time.
The Control Shaft of steam valve for steam turbine described in the utility model is provided with Locking Device, can carry out locking when valve is in certain state, ensures the stability that valve works at high temperature under high pressure.
Accompanying drawing explanation
Fig. 1 is steam valve for steam turbine described in the utility model.
Wherein: 1-steam reception unit, 2-valve body, 3-valve control device, 4-controlling rod, 5-steam monitoring device, 6-rotatable handle, 7-Control Shaft.
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 valve for steam turbine, comprises steam reception unit 1, valve control device 3, valve 2, lockable mechanism and steam monitoring device 5;
Together with described steam reception unit 1 is fastened by bolts with valve 2, described valve 2 inside is a cavity, described cavity sidewalls has a gas channel, the other end of described passage is connected with steam monitoring device 5, described valve 2 is controlled by a Control Shaft 7, described Control Shaft 7 is connected with a rotatable handle 6, and the middle part of described Control Shaft 7 is provided with a lockable mechanism, and described lockable mechanism controlling rod 4 stretches out valve body;
Thermometer and gas manometer is provided with in described steam monitoring device.
The steam valve used in the utility model is a kind ofly specifically applied in steam turbine, this valve 2 not only has the function controlling vapor flow, also there is the function of monitoring vapor (steam) temperature and pressure, steam enters into valve inner through steam reception unit 1, seal ring is provided with at steam line and steam reception unit 1 joint, in order to ensure sealability, 3 road seal rings can be set, the steam entering cavity has sub-fraction can enter in steam monitoring device 5, this device mainly monitors the temperature and pressure of steam, the control section of valve 2 is arranged on the right side of valve 2, Control Shaft 7 end is connected to rotatable handle 6, just can carry out valve 2 control by twisting rotatable handle 6, Locking Device in the middle part of Control Shaft 7 is used to locking Control Shaft 7, after valve 2 is in certain perfect condition, in order to prevent high temperature and high pressure gas, reaction is carried out to control section, Control Shaft 7 is needed to carry out locking, prevent it from loosening, so also just ensure that the stability of valve working.
In sum, every have steam reception unit, can also Real-Time Monitoring vapor (steam) temperature, carries out the multi-functional steam valve for steam turbine of valve locking all within protection domain of the present utility model by Locking Device.
