Description
【Technical field】
The utility model is related to a kind of drum, more particularly to a kind of middle pressure drum for reducing suppressed time.
【Background technology】
Drum (also known as drum) is most important pressure parts in natural circulation boiler, is mainly used in pressing high in power generation
In pressure subcritical boiler, the number that middle pressure drum of the prior art generally comprises cylindrical housings and is arranged in cylindrical housings
Individual adapter, the adapter is enclosed construction, used as pressure vessel, then generally can carry out pressure to middle pressure drum before dispatching from the factory
Test, conventional method is to squeeze into middle pressure drum water 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 the adapter headspace, cause staff to do pressure-resistant
Need to spend more suppressed times during test, greatly reduce operating efficiency.
Therefore, it is necessary to provide a kind of middle pressure drum for solving above-mentioned technical problem.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide a kind of middle pressure drum for reducing suppressed time.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of middle pressure vapour for reducing suppressed time
Bag, including：Housing, the several upper connecting tubes being arranged above housing and the several lower linking tubes being arranged at below housing, it is described on connect
The lower end of pipe is mutually welded with housing, and the upper end of the upper connecting tube is welded with pipe cap, and the upper pipe cap is provided with screwed hole, described
Plug is installed, upper end and the housing of the lower linking tube are mutually welded, and the lower end of the lower linking tube is welded with lower pipe cap in screwed hole.
Preferably, a kind of middle pressure drum for reducing suppressed time in the utility model is further arranged to：The spiral shell
Pit is arranged at the centre of pipe cap, and the plug is provided with the external screw thread closed with corresponding threaded holes.
Preferably, a kind of middle pressure drum for reducing suppressed time in the utility model is further arranged to：The shell
Body includes cylindrical body portion and is arranged at the domed ends at cylindrical body portion two ends.
Preferably, a kind of middle pressure drum for reducing suppressed time in the utility model is further arranged to：The shell
Support base is provided with below body.
Preferably, a kind of middle pressure drum for reducing suppressed time in the utility model is further arranged to：The shell
Body is additionally provided with inlet and leakage fluid dram.
Compared with prior art, the utility model has the advantages that：Middle pressure drum in the utility model passes through
One screwed hole is set on upper pipe cap, then a plug is set in screwed hole, so that can be before pressure testing by middle pressure drum
Air emptying, can substantially reduce the difficulty of suppressing of workman when suppressing, reduce the suppressed time of workman, and then improve production effect
Rate.
【Brief description of the drawings】
Fig. 1 is the structural representation of middle pressure drum in the utility model.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
Fig. 3 is the structural representation of plug in the utility model.
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 to pressing drum to be described in further detail in one kind described in the utility model.
As shown in Figure 1 to Figure 3, a kind of middle pressure drum for 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 below housing 1, the housing 1 include cylindrical body portion 10 and set
The domed ends 11 at cylindrical body portion two ends are placed in, lower end and the housing 1 of the upper connecting tube 2 are mutually welded, the upper connecting tube 2
Upper end be welded with pipe cap 4, the centre of the upper pipe cap 4 be provided with screwed hole 40, the screwed hole 40 be provided with it is stifled
First 5, the plug 5 is provided with the external screw thread 50 being engaged with screwed hole 40.The upper end of the lower linking tube 3 is mutually welded with housing 1, institute
The lower end for stating lower linking tube 3 is welded with lower pipe cap 6, and support base 7 is provided with below the housing, is additionally provided with feed liquor on housing 1 in addition
Mouth and liquid outlet (not shown).
Before pressure testing, the plug 5 on upper pipe cap 4 is opened, water is filled in the inner chamber of middle pressure drum, the sky in middle pressure drum
Gas will be emptied from screwed hole 40, after after air emptying, plug 5 is threaded into hole 40, then carry out voltage-withstand test.
In sum, the middle pressure drum in the utility model is on upper pipe cap by setting a screwed hole, then in screw thread
One plug is set in hole, so that workman can be substantially reduced when suppressing before pressure testing by the air emptying in middle pressure drum
The suppressed time suppressed difficulty, reduce workman, and then improve production efficiency.
Principle and its effect that the above embodiments only illustrative the utility model is created, and the reality that part uses
Example is applied, not for limitation the utility model；It should be pointed out that for the person of ordinary skill of the art, not departing from this
On the premise of utility model creates design, various modifications and improvements can be made, these belong to protection of the present utility model
Scope.
