Abstract
The utility model discloses a hold back device for the angle valve of an LPG cylinder. The device is arranged at the lower opening of the angle valve of the cylinder, composed of a copper pipe and a steel ball. The pipe wall of the copper pipe is provided with a plurality of small holes. The steel ball is arranged in the copper pipe. When the tank is inverted, the steel ball can freely roll in the copper pipe and seal the larynx hole of the angle valve. The utility model with the simple structure and the reliable performance can effectively prevent the household LPG cylinder from back filling an empty cylinder with the LPG.
Description
The utility model relates to the backstop of a kind of liquefied gas tank with angle valve, and it does not influence tinning and civilian.
Usually use angle valve at present on the liquefied gas tank, the jar of filling liquid gas is often arbitrarily poured in down a chimney in slack tank by some, operate dangerous, often cause deflagration accident having, threaten personal life safety, management to the liquid gas station simultaneously causes difficulty, all has every year a large amount of liquid gas to lose, and the angle valve of a large amount of liquefied pots is damaged.The design people consults great mass of data, does not see the report of relevant liquefied gas tank angle valve backstop as yet.
The purpose of this utility model is the backstop of a kind of liquefied gas tank angle valve of design, and it does not influence city gas bottling and use, goes but the liquid gas in the jar arbitrarily can not be filled in other slack tanks.
The method that realizes the utility model purpose is, end opening at the angle valve of jar, a backstop is installed, this backstop is made up of a copper pipe and steel ball, the outer side wall of copper pipe upper end is connected by the screw-internal thread fit of screw thread with the angle valve end opening, the diameter of steel ball is slightly less than the diameter of copper pipe, and steel ball places in the copper pipe, and the copper pipe sidewall has aperture.When tank body was inverted, steel ball can freely roll in copper pipe, so that stop up the larynx hole of angle valve, thus play non-return effect; When the upright placement of tank body, steel ball places the lower end of copper pipe, does not influence tank body can liquid gas and normal the use.When the can liquid gas, connecting pipeline is opened angle valve, and liquid gas enters from angle valve side mouth, through valve larynx hole, and the valve end opening, the copper pipe areole enters in the jar.When just using gas always, gas is from flowing out from valve body side mouth through above-mentioned same paths in the other direction.
Structure of the present utility model further describes by drawings and Examples.
Fig. 1 is angle valve and backstop connection diagram.
3 angle valve end openings, 4 copper pipe holes, 1 angle valve side mouth, 2 valve larynx holes, 5 copper pipes, 6 steel balls
As shown in the figure, the outside thread of the internal thread of angle valve end opening (3) and copper pipe (5) upper end matches and is connected, the lower end closed of copper pipe (5), and the tube wall of copper pipe has some apertures (4), steel ball (6) places in the copper pipe (5), and steel ball size is slightly less than the copper pipe caliber.
Claims (1)
- A kind of device of pouring in down a chimney to slack tank by the civil liquefied gas jar of preventing, it is characterized in that one backstop being installed at the angle valve end opening of liquefied gas tank, this backstop is made up of copper pipe and steel ball, the lower end closed of copper pipe, the copper pipe tube wall has some apertures, the screw thread of copper pipe upper end outer side wall and the internal thread of angle valve end opening match and are connected, and the diameter of steel ball is slightly less than the copper pipe caliber, and steel ball places in the copper pipe.
