Description
Technical field
The utility model belongs to a kind of gas cylinder, is specifically related to a kind of gas cylinder adapter assembly.
Background technique
Rock gas is as cleaning, eco-friendly power source, and country just vigorously promotes the use.Gas-fueled vehicles and town dweller's combustion gas have been listed in the project of first developing in country's " gas utilization policy ".The rock gas using method is to set up the city gas gas transmission pipeline net work, supplies with Vehicle Fueling Station and resident and uses.The CNG gas-fueled vehicles are in gas station the air cylinder compression that the rock gas high pressure is pressed into automobile to be preserved, and the steam supply car engine uses behind multi-step pressure reduction.After running out of air in the air cylinder, just need again in the gas station aerating.Because the construction of gas station requires high on safety, floor space is big, investment is big, be difficult to find suitable place in densely populated urban area, make the construction of gas station in the region with quantitatively be restricted, caused present aerating difficulty, the situation that queuing time is long does not satisfy the requirement that automobile makes things convenient for aerating.In addition, on area that does not have the natural gas supply pipe network and expressway, do not have gas station yet, influence and limited the development of gas-fueled vehicles.In the area that does not have the natural gas supply pipe network, the resident also can not use rock gas.
For breaking through the restriction that gas station and gas distributing system are built, people begin to consider directly the gas cylinder on the gas-fueled vehicles to be changed, these ventilation gas cylinders are behind factory's can compressed natural gas, be transported to the ventilation point of setting up in a large number, gas-fueled vehicles and resident only need air bottle is replaced by the gas cylinder of filling gas, can continue to use, not be subjected to the restriction of gas station and gas transmission pipeline net work fully.Therefore, but rock gas is as inflammable and explosive hazardous gas, and gas cylinder is connected just extremely important with the high pressure of supply air line, satisfy the reliable break-make that gas circuit connects, therefore a lot of technological schemes all are to adopt thread connecting mode, also will satisfy safe and efficient requirement but gas cylinder is changed, and it is just very loaded down with trivial details to be threaded, and is threaded under the situation of frequent dismounting, sealability is difficult for guaranteeing, the long-term use will influence the reliability that gas circuit connects, and causes high-pressure gas to leak.
The defective of prior art is: gas cylinder is connected threadably with supply air line, gas circuit is changed loaded down with trivial details, can not reach quick-replaceable requirement, and be threaded under the situation of frequent dismounting, sealability is difficult for guaranteeing that long-term the use will influence the reliability that gas circuit connects, cause high-pressure gas to leak, have potential safety hazard.
The model utility content
The purpose of this utility model be propose a kind of can quick-replaceable gas cylinder adapter assembly, can effectively prevent the gas leakage of jointing.
For achieving the above object, the utility model provides a kind of gas cylinder adapter assembly, the body that comprises gas cylinder, be installed with the high pressure joint seat on the bottleneck seat of this body, having pore in this high pressure joint seat communicates with described gas cylinder, the break-make of stop valve control pore is installed on the high pressure joint seat, its key is: have radial direction through hole on the described high pressure joint seat and communicate with described pore, in this radial direction through hole high pressure joint is installed, the tracheae end of this high pressure joint is connected with high-pressure air pipe, the tip side of this high pressure joint stretches in the described radial direction through hole, has air flue in this tip side, and this air flue communicates with described high-pressure air pipe;
Sidewall at described high pressure joint tip side has a circle air inlet duct, and after tip side was in place in described radial direction through hole, this air inlet duct communicated with described pore, was evenly distributed with at least two injection wells on the described air inlet duct and communicated with described air flue.
Even distribution injection well guarantees that high pressure joint in the radial direction stress balance, guarantees that high pressure joint and high pressure joint seat can long-term safety use.
On the tip side of described air inlet duct above and below, all have seal groove, seal ring and Sealing shield ring are installed in the sealing groove.
On the tip side above the described air inlet duct, have two seal grooves, on the tip side below the described air inlet duct, have two seal grooves.
Multi-layer sealed groove design, the assurance combustion gas can not leaked.
In described high pressure joint, be equipped with, after described tip side is in place in radial direction through hole, should be connected on the described high pressure joint seat from lock collar from lock collar.
Can guarantee that from lock collar high pressure joint and high pressure joint seat can accurately be in place.
Be installed with the self-locking baffle plate on the described stop valve, have the release breach on this self-locking baffle plate, the shape of this release breach and describedly match from lock collar, when stop valve is opened, when the high pressure joint seat was communicated with high pressure joint, described self-locking baffle plate was positioned at described top from lock collar, and close from lock collar, to stably be fixed on the inlet of radial direction through hole from lock collar, guarantee that high pressure joint and high pressure joint seat can keep accurate contraposition for a long time.When stop valve is closed, when high pressure joint seat and high pressure joint disconnected, described release breach was positioned at described top from lock collar, is convenient to take out high pressure joint from the high pressure joint seat.
Remarkable result of the present utility model is: provide a kind of can quick-replaceable gas cylinder adapter assembly, effectively prevent the gas leakage of jointing, and long-term the use, also can guarantee gas circuit break-make safely and reliably.
