Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a cooling mechanism for a high pressure inflator comprises an outer cylinder barrel 1, an inner cylinder barrel 2 and a third-stage compression cylinder 3, the outer cylinder barrel 1, the inner cylinder barrel 2 and the third-stage compression cylinder 3 are sequentially sleeved inwards, a piston rod 4 is movably sleeved in the third-stage compression cylinder 3, the top ends of the outer cylinder barrel 1 and the piston rod 4 are fixedly connected to a handle, the top end of the inner cylinder barrel 2 is in threaded connection with a top seal cover 5, the top seal cover 5 is positioned in the outer cylinder barrel 1, wherein an inner cavity between the outer cylinder barrel 1 and the inner cylinder barrel 2 is a first-stage compression cavity 7, an inner cavity between the inner cylinder barrel 2 and the third-stage compression cylinder 3 is a gas storage cavity 8, an inner cavity of the third-stage compression cylinder 3 is a third-stage compression cavity 10, a one-way gas inlet leather collar 6 is arranged on the outer side of the top seal cover 5, the one-way gas inlet leather collar 6 is movable, one-level compression chamber 7 can communicate with the inner chamber of outer cylinder 1, 1 interior gas compression of outer cylinder is gone into in one-level compression chamber 7, when outer cylinder 1 lifts up, the clearance of one-way leather collar 6 that admits air stops up top closing cap 5 and 1 inner wall of outer cylinder, the inner chamber and the one-level compression chamber 7 of outer cylinder 1 do not communicate, gas compression passes through the check valve in 7 one-level compression chambers gets into gas storage chamber 8, 8 interior gas pressures of gas storage chamber rise simultaneously, get into tertiary compression chamber 10 through the check valve, when outer cylinder 1 pushes down again, gas in the tertiary compression chamber 10 is compressed promptly to piston rod 4, the check valve through the base 9 that 1 bottoms of outer cylinder set up gets into the gas tube. The bottom of the air storage cavity 8 is provided with cooling liquid which can move along with the up-and-down movement of the outer cylinder barrel 1.

There is liquid separation stopper 12 at 8 inside sliding connection of gas storage chamber, compensation gas circuit 11 has been seted up to the inner wall of inner cylinder barrel 2, compensation gas circuit 11 is used for the top of intercommunication 7 inner chambers of one-level compression chamber and the bottom of 8 inner chambers of gas storage chamber, liquid separation stopper 12 is used for the separation gas storage 8 in the bottom that cooling liquid got into liquid separation stopper 12, gas filling duct 13 has been seted up at the inner wall of base 9, gas filling duct 13 is used for the bottom of intercommunication gas storage chamber 8 and the bottom of tertiary compression chamber 10, top at gas filling duct 13 is equipped with one-way pneumatic valve 14, one-way pneumatic valve 14 only is used for switching on the gas circuit of gas storage chamber 8 to the 10 directions of tertiary compression.

Therefore, when the outer cylinder barrel 1 is lifted up, gas in the compression primary compression cavity 7 enters the bottom of the gas storage cavity 8, the liquid isolating plug 12 is lifted up under the condition that the gas pressure in the gas storage cavity 8 does not reach the one-way gas pressure valve 14, so that the liquid isolating plug 12 drives the cooling liquid on the upper portion of the liquid isolating plug to lift up until the gas pressure in the gas storage cavity 8 pushes up the one-way gas pressure valve 14, the liquid isolating plug 12 does not rise any more, the gas enters the tertiary compression cavity 10 through the one-way gas pressure valve 14 and the gas charging passage 13 and presses down the outer cylinder barrel 1, on one hand, the volume of the primary compression cavity 7 is increased, the pressure is reduced, the gas in the outer cylinder barrel 1 and the gas storage cavity 8 is sucked, the liquid isolating plug 12 drives the cooling liquid to fall, on the other hand, the piston rod 4 moves down to compress the gas in the tertiary compression cavity 10 to generate high temperature, and. Through the setting, not only realized that the coolant liquid reciprocates, in time derive 3 most heats in the department of tertiary compression jar, improve the radiating efficiency, can also prevent filling gas stage in to tertiary compression chamber 10, the coolant liquid is because of the overflow gets into in tertiary compression chamber 10.

The bottom of the liquid isolating plug 12 is a conical surface, and the conical surface faces the bottom of the compensation air passage 11. So that the gas introduced into the gas storage cavity 8 by the compensation gas circuit 11 can smoothly enter the gas storage cavity 8 and lift the liquid isolating plug 12.

Wherein the volume of the first-stage compression cavity 7 is twice of the volume of the air storage cavity 8. The volume of the two times of the volume is not limited to two times, but also can be more than two times, and the function of the two times of the volume is that when the gas in the first-stage compression cavity 7 is compressed into the gas storage cavity 8, the gas can still push the liquid separation plug 12 to rise to a preset height within the compression ratio range, the one-way gas pressure valve 14 can still be jacked open, and the residual compressed gas can enter the third-stage compression cavity 10.

Wherein, the critical opening and closing force of the one-way air pressure valve 14 is half of the height of the liquid isolating plug 12 which rises to the air storage cavity 8. Specifically, the air pressure required by the liquid isolating plug 12 to rise to half of the height in the air storage cavity 8 is the gravity of the liquid isolating plug 12 and the cooling liquid on the upper portion of the liquid isolating plug divided by the bottom stress area, and under the air pressure, the air pressure multiplied by the stress area of the one-way valve core on the top of the one-way air pressure valve 14 is the critical pressure value of the action of the spring, because the stage of high temperature generation caused by the compression of the gas in the three-stage compression cavity 10 by the piston rod 4 is mainly generated on the lower half portion of the three-stage compression cylinder 3, only the cooling liquid on the upper portion of the liquid isolating plug 12 moves half of the air storage cavity 8 and can move downwards synchronously along with the downward movement of.

In order to facilitate the installation of the one-way air pressure valve 14, the one-way air pressure valve 14 can be connected to the top of the base 9 in a threaded manner in a groove in a bolt manner, specifically, the one-way air pressure valve 14 is composed of a bolt, a valve core and a spring, the bolt is hollow, an air passage penetrates through the bolt, the outer portion of the bolt is connected to the base 9 in a threaded manner, the valve core is supported at a hollow air passage port of the bolt from the lower portion, and the spring support is arranged at the lower portion of the valve core. In addition, the hollow gas at the upper part of the cooling liquid in the gas storage cavity 8 is easily pressed to generate resistance when the cooling liquid rises, so that when the gas storage cavity is installed, the inner cylinder barrel 2 can be firstly inverted, the cooling liquid is filled, the base 9 is plugged, then the outer cylinder barrel 1 is pressed downwards, and the gas at the bottom of the gas storage cavity 8 is discharged, and thus, the resistance of the compressed gas generated at the rising stage of the cooling liquid can be prevented.
