As shown in fig. 1 to 4, a gas tank inflation valve comprises: a valve body 100, a valve plug 200, and a first valve spool 300.
The valve body 100 is provided with a first valve cavity 110 and an air outlet cavity 120, and the first valve cavity 110 is communicated with the air outlet cavity 120.
A valve plug 200, which is plugged in the first valve chamber 110.
The first valve element 300 has a sealing portion 310, the first valve element 300 is movably disposed in the first valve chamber 110 and can enable the sealing portion 310 to be connected with the valve plug 200 in an abutting manner, a gas discharge gap 320 is formed between the first valve element 300 and the valve plug 200, and when the pressure of the gas discharge chamber 120 is greater than that of the first valve chamber 110, the sealing portion 310 is connected with the valve plug 200 in an abutting manner and seals the gas discharge gap 320.
In terms of specific structure, the first valve chamber 110 is used for accommodating the first valve core 300, the gas outlet chamber 120 is used for inflating the gas tank, the sealing portion 310 is actually an annular plate-shaped structure located on the first valve core 300, and the gas exhaust gap 320 is a gap between the valve body 100 and the first valve core 300.
In addition, the valve plug 200 may be detachably connected to the valve body 100, and when the first valve member 300 is pressed to exhaust gas at a too low speed, the valve plug 200 may be moved outward, and at this time, the distance from the valve plug 200 when the first valve member 300 is pressed is increased, thereby increasing the speed of exhausting gas.
It should be noted that, in the prior art, a common inflation valve only has an inflation function and does not have an air exhaust function, so that the air in the tank cannot be exhausted along with the increase of the inflation gas in the inflated tank, and thus, the air tank occupies part of the space, and therefore, the tank cannot be filled with the gas.
Thus, in the above-described embodiment, depressing the first valve spool 300 causes air to be expelled from the vent void 320 so that the pressure of the tank being inflated is reduced, thereby allowing it to be inflated again.
It should be noted that the gas tank inflation valve can automatically close the exhaust gap 320 without a spring, and since the pressure of the gas tank is higher than the outside, the pressure of the gas outlet cavity 120 is higher than that of the first valve cavity 110, and the gas in the gas tank pushes the sealing portion 310 to be in interference connection with the valve plug 200 and automatically seal the exhaust gap 320, at this time, the gas cannot be exhausted.
As shown in fig. 3 and 4, in addition to the above embodiments, the valve further includes a return elastic member 400, and two ends of the return elastic member 400 are respectively in interference connection with the first valve element 300 and the valve plug 200 and can push the sealing portion 310 to seal the exhaust gap 320.
Preferably, the elastic return element 400 is a spring, and the elastic return element 400 can return the first valve element 300, specifically, when the first valve element 300 is pressed down, the first valve element 300 is pressed down to drive the elastic return element 400 to compress, the exhaust gap 320 is communicated with the first valve chamber 110, and when the first valve element 300 is released, the elastic return element 400 extends due to its elasticity to push the sealing portion 310 to seal the exhaust gap 320.
As shown in fig. 1 and 2, in addition to the above embodiments, the valve body 100 is further provided with a first sealing ring 130, the first sealing ring 130 is located in the first valve cavity 110, and the first valve core 300 is in interference connection with the valve plug 200 through the first sealing ring 130.
Preferably, when the first valve member 300 is closed, the first valve member 300 is elastically coupled to the valve plug 200 by the first sealing ring 130, so that the gas in the first valve chamber 110 is not discharged from the gas discharge gap 320, and thus the gas canister inflation valve has excellent gas tightness.
As shown in fig. 1 and 2, in addition to the above embodiments, the valve body 100 further includes an inlet chamber 140, a second valve chamber 150, and a second valve core 500, the outlet chamber 120 communicates with the inlet chamber 140 through the second valve chamber 150, and the second valve core 500 is disposed in the second valve chamber 150 and can seal the second valve chamber 150.
Preferably, the gas of the gas tank for gas charging is communicated with the gas tank to be charged through the gas inlet cavity 140, the second valve cavity 150 and the gas outlet cavity 120, and when the second valve core 500 does not seal the second valve cavity 150, the gas is transmitted from the gas tank to be charged; when the second valve spool 500 seals the second valve chamber 150, the combustion gases are no longer transmitted.
As shown in fig. 1 and 2, on the basis of the above embodiment, the gas inlet cavity 140 and the gas outlet cavity 120 are both provided with a thimble 160 for opening the gas cylinder, and preferably, the thimble 160 is used for pushing the gas cylinder open so that the gas cylinder can perform gas exchange.
Further, the air outlet chamber 120 is communicated with the second valve chamber 150 through the thimble 160, so that the air outlet position of the inflation valve when the inflation valve inflates through the second valve chamber 150 is lower than the air outlet position of the inflation valve when the inflation valve deflates through the first valve chamber 110, thereby facilitating the air discharge.
As shown in fig. 1 and 2, in addition to the above embodiments, the gas inlet cavity 140 and the gas outlet cavity 120 are both provided with a second sealing ring 170, and the second sealing ring 170 is used for connecting with an opening of a gas tank so as to prevent gas leakage from the gas tank.
Preferably, the second sealing ring 170 is capable of sealing the opening of the gas cylinder to prevent gas leakage from the gas cylinder, and specifically, when the thimble 160 pushes the gas cylinder open, the second sealing ring 170 is just in interference connection with the opening of the gas cylinder to prevent accidents caused by gas leakage during ignition.
As shown in fig. 1 and 2, in addition to the above-described embodiments, the valve body 100 is provided with an internal thread (not shown), and the second valve body 500 is provided with an external thread (not shown), which is connected to the internal thread, so that the second valve body 500 is connected to the valve body 100.
Preferably, the second valve spool 500 is connected with the valve body 100 by external and internal threads, so that a user can control the gas delivery speed by adjusting the second valve spool 500.
As shown in fig. 1 and 2, based on the above embodiment, the second valve core 500 is hinged with a pull ring 510, and preferably, the pull ring 510 can flexibly rotate according to the requirement of the user, so as to facilitate the user to adjust the second valve core 500.
As shown in fig. 3 and 4, in terms of working principle, two different gas tanks are prepared as an inflation tank and an inflated tank, respectively, the inflation tank is connected with the gas inlet cavity 140, the inflated gas tank is connected with the gas outlet cavity 120, and the inflated gas tank can be inflated by opening the second valve core 500.
When the transportation speed between the gas cylinders is slow, the second valve core 500 can be closed, then the first valve core 300 is pressed to exhaust the air in the inflated cylinder, so that the pressure of the inflated cylinder is reduced, the second valve core 500 is firstly closed mainly to prevent the gas in the inflated cylinder from leaking out from the exhaust gap 320, and after the second valve core 500 is opened again after the second valve core is repeatedly pressed, the gas can be inflated again.
The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
