Abstract
The utility model provides a constant pressure container, which comprises a rigid cavity, a sac for storing gas or liquid, a piston and a constant force spring, wherein the sac and the piston are arranged on the inner side of the rigid cavity; the constant force spring is arranged on the outer side of the rigid cavity; and the piston extrudes the sac under the action of the constant force spring. By adopting the constant pressure container of the utility model, gas and liquid stored therein can be discharged completely, thereby improving use efficiency of the constant pressure container.
Description
Technical field
The utility model relates to a kind of pressure vessel.
Background technique
The container of existing stored-gas or liquid is generally airtight rigidity cavity, and this container is in discharge water/liquid process, and the pressure in the container can constantly descend, and the result causes the gas/liquid in the container to be difficult to discharge fully.Thereby make that the utilization efficiency of container of this stored-gas or liquid is greatly reduced.
The model utility content
In order to overcome the defective of above-mentioned prior art, inventor of the present utility model considers, keeps constant voltage in the container if utilize constant force spring to make, and the gas/liquid in the container is under the constant pressure, gas or liquid are discharged fully, thereby improved utilization efficiency.
Therefore, the purpose of this utility model is to provide a kind of pressure vessel, wherein, described pressure vessel comprises the rigidity cavity, is used for the capsule of stored-gas or liquid, piston and constant force spring, wherein, described capsule and described piston are arranged on described rigidity cavity inboard, and described constant force spring is arranged on the outside of described rigidity cavity, and described piston pushes described capsule under the effect of described constant force spring.
According to the pressure vessel of a mode of execution of the present utility model, wherein, described constant force spring is wind spring or air spring.
According to pressure vessel of the present utility model, the gas or the liquid that wherein store are discharged fully, improved the utilization efficiency of pressure vessel.
Description of drawings
Fig. 1 is the schematic representation of pressure vessel of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, be provided with piston 2 and capsule 4 in the inside of rigidity cavity 1.Wherein, piston 2 can move up and down along the inwall of rigidity cavity 1, capsule 4 then is arranged in the space that is surrounded by the bottom of rigidity cavity 1 and sidepiece and piston body 2, and the size of capsule 4 is greater than or equal to when piston 2 rises to the top of rigidity cavity 1, piston 2 and the bottom of rigidity cavity 1 and the maximum internal space that sidepiece is enclosed.
Outer installment at rigidity cavity 1 has constant force spring 3.One end of constant force spring 3 is fixed in piston 2, and the other end then is fixed in the bottom of rigidity cavity 1.
The turnover of gas or liquid for convenience has gas/liquid inlet 5 and gas/liquid outlet 6 simultaneously in the bottom of rigidity cavity 1 and capsule 4.
Because the power that has constant force spring 3 to give piston 2 in the arranged outside of pressure vessel is constant, and the stored gas of piston 2 and capsule 4 or the area of contact of liquid also be constant, thereby constituted pressure vessel of the present utility model.In the time the gas in the capsule 4 or liquid need being discharged, under the effect of constant force spring 3, piston 2 moves towards the bottom of rigid chamber body 1 rigidity cavity 1 in, so just capsule 4 stored gas or liquid can be exported 6 discharges from gas/liquid.Because gas or liquid in the capsule are under the constant voltage all the time, therefore, can be emptied completely in pressure vessel.
In addition, when the pressure of gas outside the pressure vessel or liquid during greater than the pressure in the pressure vessel, then gas or liquid then can enter the mouth by gas/liquid and 5 enter pressure vessel, at this moment, under the effect of constant force spring 3, piston 2 moves towards the top of rigid chamber body 1 in rigidity cavity 1, in the capsule 4 of so just the gas in the external world or liquid can being packed into.
Though below in conjunction with the accompanying drawings and embodiments the utility model is specified, is appreciated that above-mentioned explanation does not limit the utility model in any form.For example, in the utility model, described rigidity cavity 1 can be made by steel plate or cement board, and described capsule 4 can be made by flexible materials such as rubber or plastics, and described constant force spring 3 can be constant force wind spring or constant force air spring etc.Those skilled in the art can be out of shape and change the utility model as required under the situation that does not depart from connotation of the present utility model and scope, and these distortion and variation all fall in the scope of the present utility model.
Claims (2)
1. pressure vessel, it is characterized in that, described pressure vessel comprises the rigidity cavity, is used for the capsule of stored-gas or liquid, piston and constant force spring, wherein, described capsule and described piston are arranged on described rigidity cavity inboard, described constant force spring is arranged on the outside of described rigidity cavity, and described piston pushes described capsule under the effect of described constant force spring.
2. pressure vessel according to claim 1 is characterized in that, described constant force spring is wind spring or air spring.
