Specific embodiment
Embodiment, as shown in Figure 1:Self-locking bottle valve, including:Valve body 10, spool 20, valve rod 30, pressure cap 40, compression spring 50,
From components such as lock 60, lid 70, handwheels 80.
Wherein:
The valve body 10 has valve chamber(It is not shown on figure).The valve chamber has air inlet 111 and gas outlet 112, and the valve chamber
Upside have matching hole 113.
The spool 20 is rotatable to be located in the valve chamber, and the spool 20 and the air inlet 111, gas outlet 112 match.
That is, the spool 20 is rotated to some position, the air inlet 111 can be made to be connected with the gas outlet 112, the spool 20 rotate to
It behind another position, can block the air inlet 111 and the gas outlet 112.
The lower end of the valve rod 30 connects the top of the spool 20 and the valve rod 30 is non-rotatable relative to the spool 20.Than
Such as, the upper end of the spool 20 is equipped with the connecting plate of rectangle upwardly extended, and the lower end of the valve rod 30 is equipped with for the connection board
The U-typed bayonet entered.Meanwhile the upper end of the valve rod 30 extends upwardly to the outside of the valve chamber, and the top of the valve rod 30 is spirally connected
There is coupling nut 31.
The lower part of the pressure cap 40 is screwed onto in the matching hole 113, and the top of the valve rod 30 is from the axial line of the pressure cap 40
Position passing through from bottom to up.It is connect that is, the pressure cap 40 realizes the spool 20 and the valve rod 30 with the valve body 10, it is ensured that the valve
Core 20 and the valve rod 30 are not fallen out.
The lower end of the compression spring 50 is supported on the top of the pressure cap 40, and the top of the valve rod 30 is passed through out of this compression spring 50.
The inside from lock 60 has the inner cavity 61 for accommodating the compression spring 50.The outside from lock 60 is equipped with pressure step
62 and the lower part unidirectional ratchet 63 positioned at 62 top of pressure step.The flank of tooth of the lower part unidirectional ratchet 63 is upward.For example, lower part
The tooth form side of unidirectional ratchet 63 is that bevel edge is on one side straight flange.Also that is, each tooth form is right angled triangle.This is from lock 60
Exterior lateral sides are equipped with the sliding slot 64 in upper and lower directions extension.Meanwhile the top of the valve rod 30 is passed through from the inner cavity 61, the pressure
The upper end of spring 50 is withstood in the top edge of the inner cavity 61.Obviously, the upper opening of the inner cavity 61 has a platform to extend internally
Rank can be supported so as to the upper end of the compression spring 50, so as to have the trend moved up from lock 60.The present embodiment
In, a variety of common modes may be used, make this non-rotatable relative to the valve body 10 from lock 60 but can move up and down.
The lid 70 is set in the outside from lock 60.Obviously, which has the inside for accommodating this from lock 60
Chamber.The locating piece being fastened in sliding slot 64 is equipped in the internal chamber of the lid 70(It is not shown on figure), and the lid 70
Lower edge is equipped with top unidirectional ratchet 71.The flank of tooth of the top unidirectional ratchet 71 is downward.For example, the tooth of top unidirectional ratchet 71
Shape side is that bevel edge is on one side straight flange.Also that is, each tooth form is right angled triangle.The exterior lateral sides of the lid 70 are equipped with
Vertical convex ribs 72, and the lid 70 is fixed on the upper end of the valve rod 30 by the coupling nut 31.That is, the lid 70 relative to
The valve rod 30 is in absolute rest state.
The handwheel 80 is in the shell-like of lower openings so as to which the handwheel 80 is set in the outside of the lid 70.Under the handwheel 80
The edge and the pressure step 62 of portion's opening match.That is, the edge of the lower openings of the handwheel 80 can be pressed downward the pressure platform
Rank 62.Being internally provided with of the handwheel 80 makes convex ribs 72 be stuck in the vertical card slot in it(It is not shown on figure).
More specifically:
The lower part unidirectional ratchet 63 and the top unidirectional ratchet 71 match.That is, the lower part unidirectional ratchet 63 and the top are single
It can be interlocked to ratchet 71, so as to make the lid 70 only can single direction rotation from lock 60 relative to this.
Optimization:
The handwheel 80 and the lid 70 are connected together.Certainly, which can generate up and down relative to the lid 70
Movement on direction is still non-rotatable relative to the lid 70.
The action process of the utility model:
1st, bottle valve is opened:When rotating the handwheel 80, which is driven by the cooperation of vertical card slot and convex ribs 72 should
Lid 70 rotates, which is fixed on the valve rod 30, which rotates, and the spool 20 is driven to rotate, you can opens gas
Cylinder valve.At this point, the lower part unidirectional ratchet 63 and the top unidirectional ratchet 71 be in relatively rotatable state, during so as to rotate, this
It can constantly be moved down repeatedly from lock 60, so as to the non-rotatable rotation that the lid 70 is not interfered with from lock 60.
2nd, bottle valve is closed:When negative direction rotates the handwheel 80, the lower part unidirectional ratchet 63 and the top unidirectional ratchet 71
In relatively non-rotatable state.At this time, it may be necessary to the handwheel 80 is pressed down on, so as to which this be driven to be moved down from lock 60,
The lower part unidirectional ratchet 63 and the top unidirectional ratchet 71 is made to be detached from occlusive state, so as to which 70 side of the lid can rotate, the valve rod
30 reversely rotate, and the spool 20 is driven to rotate backward, until closing the bottle valve.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
Every equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly transported
Used in other related technical areas, it is equally included in the patent within the scope of the utility model.
