Specific embodiment
As shown in Figure 1-3, a kind of expansion drum, including tank body 1 and air bag 2 and controller 3, the bottom of tank body 1 are equipped with three
A supporting leg 4 and a water entrance, tank body 1 is interior to be equipped with air bag 2, and the inner wall of tank body 1 is equipped with pressure sensor 5, tank body 1
Gap between inner wall and air bag 2 forms gas compartment 6, and tank body 1 is equipped with the gas supplementing opening for 6 tonifying Qi of gas compartment, and gas supplementing opening is equipped with
Blowdown pipe 7, blowdown pipe 7 are equipped with motor-driven valve 72 and hand-operated valve 71, and pressure sensor 5 is electrically connected with controller 3 with motor-driven valve 72
It connects, when air bag 2 gives system water supplement, motor-driven valve 72 is in close state.Wherein, the connection type of tank body 1 and air bag 2 belongs to existing
Have technology (such as interface is connected by ring flange), therefore no longer narration in detail.
Specifically, tank body 1 is spherical shape, air bag 2 is elliposoidal in the expanded state.While expanding internal capacity, increase
Air bag 2 external surface area.Tank body 1 is spherical shape, for the can body of tank body 1 is cylindrical, in the process that air bag 2 expands
In, can have bigger space allow air bag 2 expand and avoid air bag 2 from contacting with tank body 1, that is, can be placed in tank body 1 compared with
Big air bag 2.
When the gas deficiency of gas compartment 6, air bag 2 may increase above predetermined value, be easy to cause the damage of air bag 2 in this way
It is bad, therefore, can detection gas room 6 in the following way gas it is whether sufficient.
Specifically, the inner wall of tank body 1 is equipped with bracket 8, bracket 8 is equipped with inductance switch 81, inductance switch 81 and control
Device 3 is electrically connected, and air bag 2 is equipped with iron plate 21, when air bag 2 is expanded into theoretical maximum, the spy of iron plate 21 and inductance switch 81
Head contact.Can detecte whether gas leakage also there can be a reason in corresponding gas compartment 6 when air bag 2 is expanded into theoretical maximum
The pressure value of opinion can generate signal and signal is passed to controller 3, press at this time when iron plate 21 contacts with inductance switch 81
If the numerical value that force snesor 5 detects is obvious less than normal, illustrates gas leakage or need tonifying Qi as early as possible.
In order to avoid excessively high pressure, tank body 1 is equipped with pressure relief opening, and pressure relief opening is connected to air bag 2, and pressure relief opening is equipped with pressure
Valve 9.When reaching predetermined maximum pressure, pressure valve 9, which is opened, carries out pressure release.
In the present embodiment, the lower end of supporting leg 4 is equipped with mounting plate 10, and mounting plate 10 is equipped with mounting hole.When use,
Generally all expansion drum is placed on the support frame, when in order to avoid extraneous huge vibration, the expansion drum is unstable, can pass through spiral shell
Silk insertion mounting plate 10 is installed on support frame.
In order to facilitate the expansion drum is shifted, the two sides of supporting leg 4 are removably set there are two connecting plate 11, and the lower end of connecting plate 11 is set
There is idler wheel 12, when connecting plate 11 is mounted on supporting leg 4, idler wheel 12 protrudes the lower end of supporting leg 4.When needing to shift the expansion drum,
Connecting plate 11 can be mounted on supporting leg 4, then make idler wheel 12 and ground face contact, facilitate transfer.The wherein protrusion of idler wheel 12 branch
The lower end of leg 4.Just refer to that the lower end of supporting leg 4 is higher than the lower side of idler wheel 12, in order to enable idler wheel 12 can be with ground face contact.Value
It obtains it is to be noted that the mounting plate 10 being equipped with must be the peace for the otherwise influence idler wheel 12 that can be dismantled when needing to install idler wheel 12
Dress.
Principle:
Signal is simultaneously passed to controller 3 by pressure value in 5 real-time monitoring gas compartment 6 of pressure sensor, when pressure value by
Gradual change hour then illustrates expansion drum to system water supplement, then controls motor-driven valve 72 and be in close state, at this point, even if by hand
Dynamic valve 71 is opened, and gas supplementing opening can be also in close state, when the value of detection becomes larger or unchanged (variation range is very
It is small) when, control motor-driven valve 72 is in the open state, and the opening of gas supplementing opening can be carried out by opening hand-operated valve 71.Meanwhile working as gas
When there is no water in capsule 2, pressure sensor 5 can also detect in gas compartment 6 whether gas leakage, if need tonifying Qi, specifically pressure
Signal is simultaneously passed to controller 3 by pressure value in 5 real-time monitoring gas compartment 6 of sensor, and with before expansion drum first time use
Air bag 2 in without water when gas compartment 6 in pressure value make difference, difference can be given to set a range, according to actually making
With environment and empirically determined suitable value range, when not having water in air bag 2, within the of short duration time, the difference detected is small
In the possible gas leakage of the range specification of setting, being sealed property is needed to detect；The difference detected within a certain period of time is less than setting
Range specification be normal loss, then start tonifying Qi, just stop tonifying Qi in the range of the numerical value that detects is located at setting.
The acquisition of the pressure value in gas compartment 6 when in the air bag 2 before expansion drum first time use without water, can be expansion drum and just goes out
When factory, the numerical value marked on specification is also possible to by the value that pressure sensor 5 measures.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
