The utility model uses the principle of guide wheel mechanism, adopts the material and the novel float of novel anti-liquefied petroleum gas, designs novel two-way guide wheel loading cartridge and fork, can close automatically, limit the input oil liquid gas, has guaranteed operational safety and Security.
Because the utility model is pure mechanical structure, therefore as long as guarantee machining accuracy, its input quantity and storage indication just can fit like a glove.The utility model adopts the material of novel anti-liquefied petroleum gas, novel fork and novel float, makes float remain level, and the buoyancy of float has increased by 6 times, thereby keeping precision in the motion repeatedly, reaches the technical requirements of product.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is the limit the quantity of structural representation of input device of a kind of liquefied petroleum gas for car steel cylinder combination brake switch and proporting.
Referring to accompanying drawing, a kind of liquefied petroleum gas for car steel cylinder combination brake switch and proporting input device of limiting the quantity of comprises combinaing valve body 2 and the storage indicating device that is installed on the steel cylinder 1.
Installing is limited the quantity of and is imported spool 3 in the combinaing valve body 2.Downside at the input spool 3 of limiting the quantity of is installed the input valve casing 4 of limiting the quantity of, and the input valve casing 4 of limiting the quantity of is connected with combinaing valve body 2 bottoms by connecting screw 5.One sagging poppet shaft 6 is piercing in the input valve casing 4 of limiting the quantity of, and is connected with L shaped fork 7 in being arranged on steel cylinder 1.The other end connection one float 8 at L shaped fork 7.
The input spool 3 of limiting the quantity of is installed in the air-inlet cavity 9 of limiting the quantity of of combinaing valve body 2.The sidewall of air-inlet cavity 9 of limiting the quantity of is provided with spiral-shaped guide groove 91, and the horizontal pilot pin 31 on the input spool 3 of limiting the quantity of is inserted in the spiral-shaped guide groove 91.Sagging poppet shaft 6 links into an integrated entity with horizontal pilot pin 31.Limiting the quantity of, the set gas port 21 that adds is communicated with on upside and the combinaing valve body 2 of air-inlet cavity 9.
The input valve casing 4 of limiting the quantity of is provided with inlet hole 41.Limit the quantity of to import in the valve casing 4 seal ring 42 is housed.Combinaing valve body 2 is provided with liquid outlet opening 22.
Limit the quantity of to import the downside of spool 3 and limit the quantity of and between the input valve casing 4 Returnning spring 10 is housed.
The storage indicating device comprises the pointer 11 that is installed on the combinaing valve body 2, the magnet steel 12 that is combined into one with pointer 11, be installed in and make pointer 11 cover be loaded on transparent watch glasses 13 in it on the combinaing valve body 2, and be installed in the spool magnet steel 14 that cooperate with pointer magnet steel 12 magnetic in the input spool 3 of limiting the quantity of.
