Specific embodiment
The present invention is described in detail with reference to the accompanying drawing.
A kind of new type of safe bottle valve shown in the present invention, including valve body 7,7 lower end of valve body are provided with current-limiting protection
Device 6, limiting protector 6 include main body 1, flow-limiting valve 4 and block material pipe 5, and 1 surface of main body is provided with thread segment 12, the master
The joining place of the first cavity 2 and the second cavity 3 with supplied gas transmission inside body 1, the first cavity 2 and the second cavity 3 is arranged
There is a chamfering 31；The upper end 41 of the flow-limiting valve 4 is arranged in the mounting groove 21, and the setting of lower end 42 of the flow-limiting valve 4 is the
Inside two cavitys 3.
Air flue 43 is offered in the flow-limiting valve 4,43 bottom end of air flue offers gas outlet 424, with realize the first cavity 2 with
Gas circulation between second cavity 3,4 lower end of flow-limiting valve form conical round table 422, and conical round table lower end offers air channel
423, to realize that the gas between block material pipe 5 and the second cavity 3 circulates.
The block material pipe 5 is mounted on 1 lower end of main body, and 5 upper end of block material pipe is abutted with 4 lower end surface of flow-limiting valve, block material pipe
Middle part offers airflow channel 52, and airflow channel 52 is connected with the air channel 423, and block material pipe 5 and 1 lower end of main body pass through spiral shell
Line connection, block material pipe 5 push flow-limiting valve 4 up it is mobile realize flow-limiting valve 4 with mounting groove first segment face 22 is seamless abuts.
In the present embodiment, 21 upper surface of mounting groove forms first segment face 22, and lower end surface forms second segment face
23, plane is between first segment face and second segment face where the upper end of the thread segment 12.
In the present embodiment, 21 radial section of the mounting groove product of first cavity 2 is greater than 2 radial section of the first cavity
Product, 3 radial section of the second cavity product are greater than 21 radial section of the mounting groove product of first cavity 2.
The block material pipe 5 is internally provided with filter element 51, and filter element 51 is mounted on 5 upper end of block material pipe, in this implementation
In example, filter element 51 is connected through a screw thread with block material pipe 5, is passed through filter element 51 by the air-flow of air channel 423 and is entered institute
It states in airflow channel 52.
1 surface of main body offers the venthole 11 being connected to the mounting groove 21 of the first cavity 2；As shown in figure, main
Body 1 is connect with gas cylinder 8 by the way that the thread segment of body surfaces is arranged in, and is sealed with sealing ring.
There are gaps for the mounting groove 21 of the upper end 41 of the flow-limiting valve 4 and the first cavity 2, when dismantling gas cylinder, in valve
High pressure gas is slowly flowed out by gap from gas outlet.
422 periphery of conical round table is tapered surface, and the surface roughness of tapered surface is greater than 1.6, when tapered surface and chamfering
When 31 abutting, the gap that can have suitable size between the two flows out gas.
The valve body 7 is integrally formed with limiting protector 6.
The operation principle of the present invention is that: when gas cylinder is in inflation, gas enters limiting protector 6 by valve body 7, firstly,
Then gas enters the second cavity 3 by gas outlet 424 by the first cavity 2, the air-flow for being then passed through air channel 423 passes through
Filter element 51 enters in the airflow channel 52, and after the filter element 51 in block material pipe 5 filters, gas enters gas cylinder
In 8.In addition, being the part being more easily broken off that stress is concentrated due to having screw thread and not having threaded transition portion, pass through
The height of plane is less than first segment face where the design of screw thread segment limit ensures the upper end of thread segment 12, is higher than second segment face.From
And when making new type of safe bottle valve by accidental impact, main body the first cavity 2 first segment face and second segment face range it
Interior position is more easily broken off relative to other positions.At this moment, the air pressure in gas cylinder 8 is by the past extrapolation of flow-limiting valve 4 until flow-limiting valve 4
In conical round table resist chamfering 31 to making post-rift gas leakage mouth be plugged, then the high pressure gas in gas cylinder 8 enters gear
In property management 5, air channel 423 is passed through into the air-flow for crossing filter element 51 and enters the second cavity 3, then by conical round table 422 and is fallen
The gap that angle 31 is formed enters the first cavity 2, finally slowly enters in air by gas outlet 424 from flow-limiting valve upper end 41.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore: it is all according to
The equivalence changes that structure of the invention, shape, principle are done, should all be covered by within protection scope of the present invention.
