Abstract
The invention discloses a vertical liquefied gas cylinder valve. The surface of a valve body of the valve is provided with an electronic mark; a valve port sealing piece, a valve core, an electronic mark, a valve port sealing part, a valve core, a sealing piece, a wire spring, a sliding block, a wire spring fixed seat, a spring and a spring fixed seat are arranged in the valve body; the valve port sealing pieces are provided with flow guide holes; and the valve cores are provided with flow drainage holes. When a liquefied gas cylinder with the valve is filled with liquefied gas by means of a matched liquefied gas filling gun, the liquefied gas filling gun can produce appropriate ampere force to make the sliding block move downwards if the cylinder is qualified, the inner wall of the sliding block extrudes the wire spring, and the wire spring is moved upwards to make the sealing piece move upwards, so that the filled medium can enter the liquefied gas cylinder; and otherwise, the matched liquefied gas filling gun cannot fill the cylinder, so that whether to fill the liquefied gas into the liquefied gas cylinder is automatically controlled, the phenomenon of filling without fixed points is fundamentally prevented, and the phenomenon of reuse of unqualified cylinders is prevented.
Description
Technical field
The application relates to valve technology field, particularly relates to the vertical type liquefied gas cylinder valve.
Background technique
In recent years, liquid gas, as a kind of New-type fuel, has entered rapidly huge numbers of families with convenient, fast, clean advantage, the potential safety hazard that still may exist due to the cylinder for liquefied gas that fills liquid gas, and entail dangers to is to user's the person and the safety of property.
For guaranteeing user's security of the lives and property, cylinder for liquefied gas fills and adopts fixed point to fill mode, can be the administer archive of cylinder for liquefied gas Erecting and improving, thereby stops to use the cylinder for liquefied gas of not examining, scrapping.But, due to liquid gas distributors and the supply website comparatively chaotic to management of steel bottle of liquefied petroleum gas, the non-fixed point of ubiquity cylinder for liquefied gas fills, and even uses phenomenons such as exceeding the time limit not examine steel cylinder.The liquefied gas cylinder valve used at present is a pure machinery, can only complete the charging-discharging function of physics, can not automatically control the cylinder for liquefied gas of not examining, scrapping and re-use.Cause the non-fixed point of a large amount of steel cylinders fill, inspection, still, using, there is very large potential safety hazard in the cylinder for liquefied gas scrapped.
In the undocumented file of portion, record a kind of scanning type liquefied gas inflatable gun, comprise scanner, charge gun rifle body, in addition, in the inboard of the circular arc handle guard shield of the body of cylinder for liquefied gas, post the label that shows cylinder for liquefied gas identity and information state.During actual the use, first with the scanner on scanning type liquefied gas inflatable gun, label on scanning cylinder for liquefied gas body, if label shows that this cylinder for liquefied gas is qualified, by control system, be the cylinder filling liquid gas, if this cylinder for liquefied gas is defective, for it, do not fill liquid gas, but this mode can only be that the staff is according to the label result on the scanning body, determine whether will being the cylinder filling liquid gas, can not automatically control not the process to the cylinder filling liquid gas, or can not fundamentally stop the phenomenon that re-uses of defective steel cylinder, can not stop the phenomenon that non-fixed point fills liquid gas simultaneously.
In another part of unexposed file, record a kind of liquefied gas inflation gun, can identify the label on the cylinder for liquefied gas body, if label shows that this steel cylinder is qualified, suitable Ampere force can be produced, if label shows that this steel cylinder is defective, described Ampere force can not be produced.But there is no the liquefied gas cylinder valve of matching used vertical type with it in prior art.
Summary of the invention
For solving the problems of the technologies described above, the embodiment of the present application provides a kind of vertical type liquefied gas cylinder valve, take and realizes that whether automatic control fill gas as cylinder for liquefied gas, and technological scheme is as follows:
