Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0028] In addition, it should be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and...

Abstract

The invention relates to the technical field of valve structures and discloses a coded lock valve structure. The coded lock valve structure comprises a valve assembly; the valve assembly comprises a valve body with an air flue, a coded lock assembly is arranged in the valve body in the axial direction, and the coded lock assembly comprises a locking plate assembly used for axial rotation inside the valve body to control on-off of the air flue. According to the coded lock valve structure, by arranging the locking plate assembly capable of axial rotation in the axial direction in the valve body, the locking plate assembly can be directly or indirectly driven to rotate by a corresponding code angle through an unlocking mechanism, so that after the locking plate assembly is rotated by the corresponding code angle, on-off of the air flue is controlled; accordingly, the aim that filling of filling fluid can be limited, or the filling of the filling fluid can be permitted is achieved; and according to the coded lock valve structure, limiting filling safety is high, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of 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-filling is v...
