Embodiment 1

[0037] Such as Figure 1 to Figure 12 As shown, the outer wall of the valve body 11 has a side connection portion 111 that can be connected to an air gun, and the inner end of the side connection portion 111 has an air inlet and outlet port 1110 communicating with the air channel M. The combination lock valve structure includes a combination lock assembly 2 that can control the opening or closing of the air inlet and outlet 1110 to control the opening and closing of the airway M. The combination lock assembly 2 is connected to the side portion 111 of the valve body 11 . Specifically, the combination lock assembly 2 may include a fixed cylinder 21, a sealing ball 22 and a combination lock 23. One end of the fixed cylinder 21 extends into the side connection portion 111 of the valve body 11 to form a fixed connection and communication. The combination lock 23 is arranged on the fixed cylinder 21. Between the side connection part 111, here, the fixed cylinder 21 has an inner cavi...

Embodiment 2

[0056] Such as Figure 13 As shown, the bottom end of the above-mentioned valve body 11 has an extension part 112 that can be connected with a gas cylinder (liquefied gas cylinder, oxygen gas cylinder, etc.), and the extension part 112 communicates with the above-mentioned air passage M, and the above-mentioned combination lock assembly 2 is arranged on the inside the extension 112 . Specifically, one end of the above-mentioned fixed cylinder 21 protrudes into the extension part 112 to form a fixed connection and communication. 23 is specifically located in the extension portion 112, and the sealing ball 22 is located in the fixed cylinder 21; here, the fixed cylinder 21 is provided with a vent hole 2100 communicating with the air passage M, and the sealing ball 22 can block the vent hole 2100 under the action of the fluid. Obstructing the airway M is achieved.

[0057] Such as Figure 13 and Figure 14 As shown, in this embodiment, the combination lock 23 may include a co...

Abstract

The invention relates to the technical field of structures of gas cylinder valves and discloses a coded lock valve structure. The coded lock valve structure comprises a valve assembly which comprises a valve body with a gas channel; the valve body is provided with a coded lock assembly capable of controlling the on-off of the gas channel; and the coded lock assembly comprises a fixing barrel connected to the valve body and communicated with the gas channel, a sealing ball movably arranged in the fixing barrel and used for blocking the gas channel, and a coded lock arranged between the fixing barrel and the valve body and capable of abutting against and ejecting the sealing ball so as to remove blocking of the sealing ball on the gas channel. In this way, by arranging the sealing ball and the coded lock matched with the sealing ball in an abutting and ejecting manner in the fixing barrel, in the locked state of the coded lock, the coded lock is separated from the sealing ball, and filling of fluid can push the sealing ball to perform sealing and blocking so as to block the gas channel and achieve the purpose of limiting filling; and in addition, in the unlocked state of the coded lock, filling of the fluid can push the coded lock to make the coded lock abut against and eject the sealing ball so as to remove blocking on the gas channel, the filling purpose can be achieved, and the valve structure is high in filling limiting safety and easy to operate.

Description

technical field [0001] The invention relates to the technical field of gas cylinder valve structures, in particular to a combination lock valve structure. Background technique [0002] Liquefied petroleum gas, oxygen, hydrogen, carbon dioxide and other gases are commonly used in daily production and life, and these gases are generally flammable, high-pressure, and very dangerous. Some gases cannot be mixed with other gases, otherwise it will cause serious safety accidents. For example, if hydrogen is filled in an oxygen cylinder, it will cause an explosion during use. Liquefied petroleum gas occupies a large market share in China because of its cleanliness and environmental protection. However, due to its high risk, the accident rate is still high, and because it is used in public places, once an accident occurs, it will cause great harm. [0003] At present, liquefied petroleum gas is filled at fixed points according to safety regulations, but due to various reasons, cross...
