Abstract
The invention relates to a medium pressure steam drum capable of shortening pressurizing time. The medium pressure steam drum comprises a shell, a plurality of upper joint pipes arranged on the shell and a plurality of lower joint pipes arranged under the shell; the lower end of each upper joint pipe is welded with the shell; the upper end of each upper joint pipe is welded with an upper pipe cap; a threaded hole is formed in each upper pipe cap and is internally provided with a plug; the upper end of each lower joint pipe is welded with the shell; and the lower end of each lower joint pipe is welded with a lower pipe cap, thus air in the medium pressure steam drum can be emptied before pressure testing, the pressurizing difficulty of a worker can be greatly lowered during pressurizing, the pressurizing time of the worker is shortened, and the production efficiency is improved.
Description
【Technical field】
The present invention relates to a kind of drum, more particularly, to a kind of middle pressure drum reducing suppressed time.
【Background technology】
Drum (also known as drum) is most important pressure parts in natural circulation boiler, is mainly used in power generation pressing height
In pressure subcritical boiler, middle pressure drum of the prior art generally comprises cylindrical housings and is arranged at the number in cylindrical housings
Individual adapter, described adapter is enclosed construction, as pressure vessel, then generally individually can carry out pressure by centering pressure drum before dispatching from the factory
Test, conventional method is to squeeze into water in middle pressure drum to carry out voltage-withstand test, when water fills whole housing cavity soon, middle pressure
Air in drum can go to the top of several adapters, due to the presence of this adapter headspace, leads to staff to do pressure
Need during test to spend more suppressed times, greatly reduce operating efficiency.
Therefore, it is necessary to provide a kind of middle pressure drum solving above-mentioned technical problem.
【Content of the invention】
For solving the above problems, it is an object of the invention to provide a kind of middle pressure drum reducing suppressed time.
For achieving the above object, the technical scheme that the present invention takes is：A kind of middle pressure drum reducing suppressed time, bag
Include：Housing, it is arranged at the several upper connecting tubes above housing and is arranged at several lower linking tubes below housing, under described upper connecting tube
End is welded with pipe cap with the welding of housing phase, the upper end of described upper connecting tube, and described upper pipe cap is provided with screwed hole, described screwed hole
Plug is inside installed, the upper end of described lower linking tube is welded with housing phase, and the lower end of described lower linking tube is welded with lower pipe cap.
Preferably, one of present invention can reduce the middle pressure drum of suppressed time and be further arranged to：Described screwed hole
It is arranged at the centre of pipe cap, described plug is provided with the external screw thread closing with corresponding threaded holes.
Preferably, one of present invention can reduce the middle pressure drum of suppressed time and be further arranged to：Described housing bag
The domed ends including cylindrical body portion and being arranged at cylindrical body portion two ends.
Preferably, one of present invention can reduce the middle pressure drum of suppressed time and be further arranged to：Described housing
Lower section is provided with support base.
Preferably, one of present invention can reduce the middle pressure drum of suppressed time and be further arranged to：Described housing is also
It is provided with inlet and leakage fluid dram.
Compared with prior art, the present invention has the advantages that：Middle pressure drum in the present invention passes through in upper pipe cap
One screwed hole of upper setting, then one plug is set in screw thread in the hole, thus can be by the air row in middle pressure drum before pressure testing
Sky, can substantially reduce the difficulty of suppressing of workman when suppressing, and reduce the suppressed time of workman, and then improve production efficiency.
【Brief description】
Fig. 1 is the structural representation of middle pressure drum in the present invention.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
Fig. 3 is the structural representation of plug in the present invention.
In figure：1st, housing, 10, cylindrical body portion, 11, domed ends, 2, upper connecting tube, 3, lower linking tube, 4, upper pipe cap,
40th, screwed hole, 5, plug, 50, external screw thread, 6, lower pipe cap, 7, support base.
【Specific embodiment】
Below by specific embodiment, pressure drum in one kind of the present invention is described in further detail.
As shown in Figure 1 to Figure 3, a kind of middle pressure drum reducing suppressed time, including：Housing 1, it is arranged on housing 1
Several upper connecting tubes 2 of side and the several lower linking tubes 3 being arranged at housing 1 lower section, described housing 1 includes cylindrical body portion 10 and sets
It is placed in the domed ends 11 at cylindrical body portion two ends, the lower end of described upper connecting tube 2 and housing 1 mutually weld, described upper connecting tube 2
Upper end be welded with pipe cap 4, the centre of described upper pipe cap 4 is provided with screwed hole 40, is provided with stifled in described screwed hole 40
5, described plug 5 is provided with the external screw thread 50 matching with screwed hole 40.The upper end of described lower linking tube 3 and housing 1 mutually weld, institute
The lower end stating lower linking tube 3 is welded with lower pipe cap 6, and the lower section of described housing is provided with support base 7, is in addition additionally provided with feed liquor on housing 1
Mouth and liquid outlet (not shown).
Before pressure testing, the plug 5 on upper pipe cap 4 is opened, water is filled the sky in the inner chamber of middle pressure drum, in middle pressure drum
Gas will empty from screwed hole 40, after air emptying, plug 5 is threaded in hole 40, then carries out voltage-withstand test.
In sum, the middle pressure drum in the present invention passes through to arrange a screwed hole on upper pipe cap, then in screw thread in the hole
One plug of setting, thus beating of workman can be substantially reduced when suppressing by the air emptying in middle pressure drum before pressure testing
Pressure difficulty, reduces the suppressed time of workman, and then improve production efficiency.
The above embodiments only principle of illustrative the invention and its effect, and the enforcement that part is used
Example, not for the restriction present invention；It should be pointed out that for the person of ordinary skill of the art, creating without departing from the present invention
On the premise of making design, some deformation can also be made and improve, these broadly fall into protection scope of the present invention.
