Abstract
The invention relates to a tube type multistage water seal structure. The tube type multistage water seal structure is composed of multistage sleeve type water seals, wherein the multistage sleeve type water seals are connected in series, the stage number n in series is a natural number which is greater than 2, and the height of the sleeve type water seals and the stage number n in series are determined according to the field installation height. The sleeve type water seals are composed of water injection/discharge parts, air discharge parts and water seal parts, wherein the water seal parts are connected in series at multiple stages, so that the water seal effect is achieved, the water injection/discharge parts are formed on the lower parts of the water seal parts, and the air discharge parts are formed on the upper parts of the water seal parts. The water seal parts are connected in series at multiple stages, so that the water seal effect is achieved. The tube type multistage water seal structure has the characteristics of small occupied area, convenience in installation and operation, good sealing effect and the like.
Description
Technical field
The present invention relates to a kind of shell and tube multilevel water seal structure, it is adaptable to turbine steam seal system。
Background technology
Water seal is the indispensable important component part of turbine steam seal system, and the work efficiency of steam turbine is had a significant impact by the performance of turbine steam seal system。Leak into reduce air, improve unit safety and economy, the Chinese scholars research to being devoted to water seal for many years, occur in that many different sealing structure for water successively。
The problems such as different types of water seal has the respective scope of application and pluses and minuses, and it is big that they ubiquities take up an area space, installs inconvenience, operating difficulties, make troubles to in-site installation。In order to solve problem above, necessary sealing structure for water is improved, invent a kind of novel sealing structure for water。
Summary of the invention
The features such as it is an object of the invention to provide turbine steam seal system water seal, it is little that the present invention has floor space, easy for installation, easy to operate, good sealing effect。
The technical scheme is that
Shell and tube multilevel water seal structure, it is characterised in that: being made up of the bushing type water seal of plural serial stage, series connection progression n is the natural number more than 2。
Described bushing type water seal by noting/discharge water part, air bleeding portion, water-sealing part form, water-sealing part plural serial stage, it is achieved water seal effect, set in the bottom of water-sealing part and note/discharge water part, set air bleeding portion on the top of water-sealing part。
Described water-sealing part is made up of water-sealed cylinder, water seal bend pipe and water seal sleeve pipe, one end of water seal sleeve pipe and water-sealed cylinder link into an integrated entity, water seal bend pipe one end is inserted in water seal sleeve pipe, and the other end is also drawn by water-sealed cylinder, and water-sealed cylinder opposite side draws an inlet duct。
Described note/drainage part is divided and is included closure plate, vacuum valve or water-sealed valve, and closure plate is placed in the water seal sleeve pipe other end and introduction pipe, and pipeline is installed vacuum valve or water-sealed valve。
Described air bleeding portion includes closure plate and vacuum valve or water-sealed valve, and closure plate is placed in water-sealed cylinder and introduction pipe, and pipeline is installed vacuum valve or water-sealed valve。
The shell and tube multilevel water seal structure of the present invention can be fixed on any concrete column at scene by support or between column, also can do support from ground and support。According to in-site installation height, determine bushing type water seal height and series connection progression。
The structure of the present invention meets the water seal requirement of turbine steam seal system, optimizes occupation of land space, optimizes mounting means, and make operation more convenient。The present invention is applicable to turbine steam seal system。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
Fig. 2 is the bushing type water seal schematic diagram of the present invention。
Detailed description of the invention
In conjunction with accompanying drawing, the invention will be further described。
As shown in Figure 1 and Figure 2, the present invention is made up of the bushing type water seal of 5 grades of series connection, described bushing type water seal by noting/discharge water part 1, air bleeding portion 3, water-sealing part 2 form, described water-sealing part 2 is made up of water-sealed cylinder 2-1, water seal bend pipe 2-2 and water seal sleeve pipe 2-3, one end of water seal sleeve pipe 2-3 and water-sealed cylinder 2-1 link into an integrated entity, water seal bend pipe 2-2 one end is inserted in water seal sleeve pipe 2-3, the other end is also drawn by water-sealed cylinder 2-1, and water-sealed cylinder 2-1 opposite side draws an inlet duct；Described note/part that discharges water 1 includes closure plate 1-2, water-sealed valve 1-1, and closure plate 1-2 is placed in the water seal sleeve pipe 2-3 other end and introduction pipe, and pipeline is installed water-sealed valve 1-1；Described air bleeding portion 3 includes closure plate 3-2 and vacuum valve 3-1, closure plate 3-2 and is placed in water-sealed cylinder 2-1 and draws another pipeline, and another pipeline is installed vacuum valve 3-1。
The shell and tube multilevel water seal structure of the present invention can be fixed on any concrete column at scene by support or between column, also can do support from ground and support。According to in-site installation height, determine bushing type water seal height and series connection progression。
As it is shown in figure 1, the present invention is made up of the bushing type water seal of plural serial stage, according to in-site installation height, determine bushing type water seal height and progression, i.e. parameter height h and series connection progression n。The present invention can pass through support 4 and be fixed on any concrete column at scene or between column, also can do support from ground and support。There is floor space little, easy for installation, easy to operate, the feature such as good sealing effect。
As it is shown in figure 1, the gland steam heater that a mouth connects turbine steam seal system dredges outlet, b mouth connects condenser or the hydrophobic entrance of steam exhaust device。
As in figure 2 it is shown, c mouth connects the inlet duct d mouth of upper level bushing type water seal, d mouth connects the c mouth of the water seal bend pipe 2-2 of next stage bushing type water seal。
After the present invention installs, open gas vent, fill water by water filling port, utilize the pressure reduction in Multi-stage sleeve formula water seal to connect, it is achieved water seal effect。The water seal of the present invention is respond well。
