Description

Valve-regulated caisson
Technical field
The utility model relates to a kind of caisson, and particularly a kind of valve-regulated caisson is used for the pneumatic system that any needs possess the gas storage function.
Background technique
At present; a kind of special-purpose gas holder (see figure 1) is arranged on the market; this gas holder is mainly by tank body 1a; cover 2a; suction port 3a; relief opening 4a; support 5a; compositions such as sewage draining exit 6a; wherein; tank body 1a is a hollow body; the pressurized air of outside enters into tank body 1a by suction port 3a and stores; the storage volume of tank body 1a is the volume of tank body; pressure is consistent with the pressurized air pressure of outside; when the gas in the needs use gas holder; just open the relief opening 4a of gas holder; pressurized air among the tank body 1a just flows out by relief opening 4a; in realization work; usually can need very jumbo pressurized air; along with pressurized air flows out from relief opening 4a; gas pressure intensity among the tank body 1a progressively reduces; suction port 3a is owing to be in normally open always; the pressurized air of outside just replenishes in gas holder simultaneously; and the air displacement of gas holder relief opening 4a is far longer than the air inflow of suction port 3a (because of thinner with the joining extraneous compressed air line of suction port 3a; air mass flow is less than the flow of air outlet), the gas pressure intensity in the gas holder just can descend always.After the pressurized air in the gas holder in the working procedure uses end, just close the relief opening 4a of gas holder, stop exhaust, and suction port 3a continues inflation, gas pressure intensity in the gas holder rises again gradually, just stop when consistent with outside pressurized air pressure when rising to, gas holder is worked so again and again.But still there is following a few point defect in this gas holder:
1) the losses of compressed air amount is big, and gas effciency is lower.Because the relief opening 4a of gas holder is when work, be in open fully, directly be discharged into the outside, gas flow rate is very fast, and when gas during as cooling medium, because gas flow rate is too fast, most of gas flows away from the object next door that needs are cooled fast, heat exchange is insufficient, and air utilization ratio is low.
2) the tank body volume of gas holder is bigger, and inconvenience is installed and used at the scene.Because the pressurized air utilization ratio in the gas holder is low, at work, about the volume of gas storage tank of selecting for use generally was twice than real work desired compression air, the volume of gas holder was just relatively big like this, and relatively difficulty just is installed in the production scene.
3) in the gas holder gas replenishment process, bigger to the pneumatic system influence that is associated.Because volume of gas storage tank is bigger, in use, when relief opening 4a opens, gas holder is in complete drain charge state, that is to say, after the gas in the gas holder will be drained fully, the jar internal air pressure is well below the air supply system that is connected with the suction port 3a specified pressure of (figure does not show), like this, suction port 3a just is in nearly passive state when make-up gas, make the compressed-air actuated flow that enters gas holder by suction port 3a show quite greatly at this moment, thereby make the pneumatic system that is associated just can't set up the minimum required pressure of work, cause the pneumatic system malfunction.
Summary of the invention
