Abstract
The utility model discloses a stabiliser for nuclear power station, it includes the stabiliser casing, connect in the relief valve at stabiliser casing top take over, formed at the water seal structure of relief valve takeover department to reach the montage just is located water seal structure below on the stabiliser casing stabiliser shower, wherein, be equipped with the capillary between water seal structure and the stabiliser shower. Compared with the prior art, a capillary is add between the new stabiliser for nuclear power station's of this practicality stabiliser shower and the water seal structure, the water seal can be formed fast, reliably. Furthermore, the utility model discloses stabiliser for nuclear power station simple structure, easy to carry out does not influence the operation of current system and equipment.
Description
Technical field
The utility model belongs to technical field of nuclear power, and more particularly, the utility model relates to a kind of used in nuclear power station voltage stabilizer fast reliably can setting up water seal.
Background technology
Voltage stabilizer is one of vitals of nuclear power station, and in the operational process of nuclear power station, in order to ensure the sealing of safety valve, safety valve connecting pipe entrance ozzle place need be provided with water seal.
Water seal near voltage stabilizer top inner wall face, is formed by saturated vapour condensation usually.But in the actual moving process of nuclear power station, the coated heat-insulation layer of the outside surface due to voltage stabilizer, steam-condensation limited efficiency, water seal is longer for Time Created, have impact on safety valve sealing property.If effective water seal can not be set up before reaching hot shutdown platform, nuclear power station can be caused to extend start-up time, be unfavorable for the economy of nuclear power station.
In view of this, necessaryly a kind of used in nuclear power station voltage stabilizer fast reliably can setting up water seal is provided.
Utility model content
The purpose of this utility model is: provide a kind of used in nuclear power station voltage stabilizer fast reliably can setting up water seal.
In order to realize foregoing invention object, the utility model provides a kind of used in nuclear power station voltage stabilizer, it sealing structure for water comprising voltage stabilizer housing, be connected to the safety valve connecting pipe of voltage stabilizer case top, be formed at safety valve connecting pipe place, and to be connected on voltage stabilizer housing and the voltage stabilizer shower be positioned at below sealing structure for water, wherein, kapillary is provided with between described sealing structure for water and voltage stabilizer shower.
One as the utility model used in nuclear power station voltage stabilizer is improved, and described kapillary upwards leads to sealing structure for water from voltage stabilizer shower.
One as the utility model used in nuclear power station voltage stabilizer is improved, and described kapillary is arranged along the inside surface of voltage stabilizer housing.
One as the utility model used in nuclear power station voltage stabilizer is improved, and the diameter of described kapillary is 0.8 to 5 millimeter.
One as the utility model used in nuclear power station voltage stabilizer is improved, the coated heat-insulation layer of described voltage stabilizer housing outer surface.
Compared with prior art, the new used in nuclear power station voltage stabilizer of this practicality has the following advantages: set up a kapillary between voltage stabilizer shower and sealing structure for water, utilize the drive ram in voltage stabilizer shower, make a small amount of shower water enter sealing structure for water, quickly and reliably can form water seal.In addition, the utility model used in nuclear power station stabilizator structure is simple, easy to implement, does not affect existing system and equipment operation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model used in nuclear power station voltage stabilizer and technique effect thereof are described in detail, wherein:
Fig. 1 is the structural representation of the utility model used in nuclear power station voltage stabilizer.
Embodiment
In order to make goal of the invention of the present utility model, technical scheme and technique effect thereof more clear, below in conjunction with the drawings and specific embodiments, the utility model is further described.Should be understood that, the embodiment described in this instructions is only used to explain the utility model, is not intended to limit the utility model.
Refer to shown in Fig. 1, for the structural representation of the utility model used in nuclear power station voltage stabilizer, it comprise the coated heat-insulation layer of outside surface (not shown) voltage stabilizer housing 10, be connected to the safety valve connecting pipe 20 at voltage stabilizer housing 10 top, be formed at the sealing structure for water 30 at safety valve connecting pipe 20 place, and to be connected on voltage stabilizer housing 10 and the voltage stabilizer shower 40 be positioned at below sealing structure for water 30, wherein, kapillary 50 is provided with between sealing structure for water 30 and voltage stabilizer shower 40.
Kapillary 50 upwards leads to sealing structure for water 30 from voltage stabilizer shower 40, and arranges along the inside surface of voltage stabilizer housing 10.Kapillary 50 is thin as far as possible, and diameter is 0.8 to 5 millimeter, and its flow is minimum, therefore can not affect spraying effect.
In operational process, the temperature of shower water is a little less than the temperature of saturated vapour, and in the process flowed along kapillary 50, shower water is constantly heated, and density reduces, for fluid flows upward provides extra driving force.In addition, the saturated vapour in shower water and voltage stabilizer has a narrow range of temperature, and the thermal stress caused voltage stabilizer wall is less.
Compared with prior art, the utility model used in nuclear power station voltage stabilizer has the following advantages:
In the utility model used in nuclear power station voltage stabilizer, set up a kapillary 50 between voltage stabilizer shower 40 and sealing structure for water 30, utilize the drive ram in voltage stabilizer shower 40, make a small amount of shower water enter sealing structure for water 30, quickly and reliably can form water seal.In addition, the utility model used in nuclear power station stabilizator structure is simple, easy to implement, does not affect existing system and equipment operation.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
