Abstract
The utility model discloses an anti-theft gas cylinder valve which comprises a valve body (1), wherein the valve body (1) is provided with an air inlet (1.1) and an air outlet. The anti-theft gas cylinder valve further comprises a plug head (2) with a handle portion (2.1), a plug head upper base (3) and a plug head lower base (4), the plug head upper base (3) is provided with a first through hole (3.1), and the plug head lower base (4) is provided with a second through hole (4.1) and used to hold a groove (4.2) of the handle portion (2.1). The plug head upper base (3) and the plug head lower base (4) are arranged in the air inlet (1.1) and the plug head upper base (3) is arranged above the plug head lower base (4). The first through hole (3.1) is arranged above the groove (4.2). The handle portion (2.1) can be movably sleeved in the groove (4.2) in an axial mode. When a gas cylinder valve stands upside down, the plug head (2) falls into the lower end port of the first through hole (3.1) and seals the lower end port of the first through hole (3.1). The anti-theft gas cylinder valve can prevent liquid state gas from flowing out when bottled gas stands upside down and the gas cylinder valve is opened.
Description
Technical field
The utility model relates to cylinder valve, relates to or rather a kind of anti-theft gaseous cylinder valve.
Background technique
Bottled combustion gas (such as liquefied petroleum gas) is the widely used gas storage of urban and rural residents and cask.Cylinder valve is opened in bottled combustion gas just immediately gas output, and opening cylinder valve when bottled combustion gas is stood upside down is that liquid combustion gas is flowed out.Some lawless person utilizes these characteristics of combustion gas in the steel cylinder that bottled combustion gas is stood upside down and steals gas, thereby brings loss to the user.
At present, common anti-theft gaseous measure is easily to tear mashed big envelope one of gas cylinder cylinder valve mouth upper envelope, and the above is with sealing and anti-fake print.Yet this measure is capable of preventing gas not stolen gas before use in advance, and used gas cylinder behind the big envelope of dismantling without any prevention effect, and be facts have proved that this measure is also also ineffective.The gas-thief seals up after can easily big envelope being opened and stealing gas again, or uses good enough to pass for genuine big envelope for it, and is hard to guard against.
The model utility content
The technical problems to be solved in the utility model is that a kind of anti-theft gaseous cylinder valve that cylinder valve can prevent that liquid combustion gas from flowing out of opening when bottled combustion gas is stood upside down is provided.
Technical solution of the present utility model is, a kind of anti-theft gaseous cylinder valve with following structure is provided, and comprises valve body, and described valve body is provided with suction port and air outlet; Also comprise the obstruction head with shank, be provided with an obstruction seat of honour of the first through hole and be provided with the second through hole and be used for holding lower of the obstruction head of the groove of described shank; A described obstruction seat of honour and lower of obstruction head all are located in the described suction port and a described obstruction seat of honour is positioned at the described top of stopping up lower of head; Described the first through hole is positioned at the top of described groove; Described shank can be linked in the described groove axially and movably; Describedly when cylinder valve stands upside down stop up in the lower end mouth that head falls into the first through hole and seal the first through hole lower end mouth.
After adopting above structure, anti-theft gaseous cylinder valve of the present utility model compared with prior art, has the following advantages:
Stop up head, stop up a seat of honour and stop up lower of head because anti-theft gaseous cylinder valve of the present utility model comprises; When cylinder valve just immediately, open cylinder valve, combustion gas by stopping up lower of head the second through hole and first through hole at an obstruction seat of honour, cylinder valve is normally given vent to anger; When cylinder valve stood upside down, blocking chock plug Action of Gravity Field stopped up in the lower end mouth that head falls into the first through hole and seals the first through hole lower end mouth, opens like this cylinder valve, just can not flow out liquid combustion gas, plays the effect that prevents from stealing gas.
As a kind of improvement of the present utility model, also be provided with in the described suction port and press mother, the described mother of pressure is positioned at the described below of stopping up lower of head.After adopting this kind structure, described pressure mother can prevent from installing front destruction Inner Dimension.
As another kind of improvement the of the present utility model, the length of the shank of described obstruction head is greater than the length of described obstruction mobilizable distance.After adopting this kind structure, avoid stopping up a shank and break away from groove, stopping up head can only be along its axial motion.
Also have a kind of improvement as of the present utility model, the lower end mouth of described the first through hole is provided with the conical surface; The described upper end portion of stopping up head is provided with rounding.After adopting this kind structure, so that the sealing between the lower end mouth of obstruction head and the first through hole is better.
