Abstract
The utility model discloses a kind of economizing type gas cylinders, including bottle body, spring, piston, gas cylinder mouth, valve；One end of the spring connects piston, and the other end is connected on the inner wall of gas cylinder bottom；The piston is located in gas cylinder, can move up and down along bottle body, the mobile effective volume that can change gas cylinder of piston；When to the utility model inflating gas cylinder, due to being filled with for extraneous gas, the gas pressure intensity of upper piston area be will increase, and spring can be compressed, gas can be full of entire gas cylinder, when gas cylinder is deflated, the gas pressure intensity of upper piston area reduces with the discharge of gas, and piston can rise under the action of the spring, reduce the effective volume of gas cylinder, the reduction of gas pressure intensity in gas cylinder can be slowed down, so that gas is fully utilized, the use cost of saving gas.
Description
Technical field
The utility model relates to a kind of gas cylinder more particularly to a kind of economizing type gas cylinders.
Background technique
It is frequently necessary to use various gases in the experiment of the industries such as chemistry, material, biology, gas used often uses gas cylinder
Storage, during gas use, the gas pressure intensity in gas cylinder can be gradually decreased, to the pressure of gas in gas use process
Certain requirement is had by force, and when the gas pressure intensity in gas cylinder is lower than certain numerical value, which is needed replacing, at this moment in gas cylinder
There is quite a few gas that cannot be fully utilized, causes the increase of gas use cost.It can be seen that existing gas cylinder up for
It is further to improve.
Summary of the invention
The purpose of this utility model is to provide a kind of economizing type gas cylinders, gas when using the novel gas bottle, in gas cylinder
It can be fully utilized, the use cost of saving gas.
To achieve the goals above, technical solution provided by the utility model is:
The utility model discloses a kind of economizing type gas cylinders, including bottle body, spring, piston, gas cylinder mouth, valve；The bullet
One end of spring connects piston, and the other end is connected on the inner wall of gas cylinder bottom；The piston is located in gas cylinder, can be above and below bottle body
It is mobile, the mobile effective volume that can change gas cylinder of piston；When to the utility model inflating gas cylinder, due to filling for extraneous gas
Entering, the gas pressure intensity of upper piston area will increase, and spring can be compressed, and gas can be full of entire gas cylinder, when gas cylinder is deflated, piston
The gas pressure intensity on top reduces with the discharge of gas, and piston can rise under the action of the spring, subtract the effective volume of gas cylinder
It is small, the reduction of gas pressure intensity in gas cylinder can be slowed down, so that gas is fully utilized, the use cost of saving gas.
The advantageous effects of the utility model are:
The utility model gas cylinder solves the problems, such as that gas cannot be fully utilized in common gas cylinder, when the gas in gas cylinder
When surplus is few, remain to make the pressure of gas in gas cylinder to meet the requirement used.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of utility model；
In figure: 1- bottle body, 2- spring, 3- piston, 4- gas cylinder mouth, 5- valve.
Specific embodiment
The utility model is described in further detail with concrete operations mode with reference to the accompanying drawing.
In conjunction with attached drawing, a kind of economizing type gas cylinder, including bottle body 1, spring 2, piston 3, gas cylinder mouth 4, valve 5.The one of spring 2
End connection piston 3, the other end are connected on the inner wall of gas cylinder bottom, and piston 3 is located in gas cylinder, can move up and down along bottle body 1.
When using the novel gas bottle, when to the utility model inflating gas cylinder, gas will enter gas cylinder from gas cylinder mouth 4
Interior, the pressure of 3 upper gas of piston is since extraneous gas is into that can become larger, and under the action of gas pressure intensity, spring 2 can be pressed
Contracting, piston 3 can be moved down along bottle body 1, and the effective volume of gas cylinder can become larger, when using gas in gas cylinder, gas from
Gas cylinder mouth 4 is discharged, and the gas pressure intensity on 3 top of piston can reduce, and piston 3 can rise under the action of spring 2 along bottle body 1, gas cylinder
Effective volume can reduce, the reduction that can slow down 3 upper gas pressure of piston is remained to when gas surplus amount is less in gas cylinder
Meet the requirement used.
It should be noted that under the introduction of this specification, any equivalent substitute side that those skilled in the art are made
Formula or obvious variant, should be covered by the scope of the present utility model within.
