Abstract
The utility model relates to a non-detachable dimethyl ether cylinder valve which comprises a valve body (1), wherein a valve (2), a gland nut (5) and a retainer ring (6) are arranged in the valve body (1) sequentially from bottom to top, and a valve rod (3) is positioned in the valve body (1) and penetrates through the valve (2), the gland nut (5) and the retainer ring (6). The valve rod (3) drives the valve (2) to move vertically to open and close the cylinder valve. An annular step is formed at the lower portion of the valve rod (3) in a protruding mode, the lower end of the gland nut (5) blocks the boss, and a necking portion is arranged at the upper end of the valve body (1) to limit the retainer ring (6) in the necking portion. The non-detachable dimethyl ether cylinder valve is simple in structure, has few parts and cannot be detached by means of the blocking of the gland nut and the necking portion at the upper portion of the valve body. Compared with the traditional structural style, manufacture and assembly cost of the non-detachable dimethyl ether cylinder valve can be greatly reduced, and the non-detachable dimethyl ether cylinder valve has good non-detachable performance.
Description
Technical field
The utility model relates to the non-dismountable cylinder valve of a kind of dimethyl ether, belongs to cylinder valve technical field.
Background technique
Cylinder valve, because of its particularity, requires it to possess non-dismountable property, otherwise very easily can, because of people's random dismounting and assembling, the generation of the phenomenons such as gas leakage very easily can occur; Each manufacturer all adopts variety of way to realize this purpose for this reason, and generally speaking its its structure of non-dismountable structural type of existing cylinder valve is generally comparatively complicated, and component are numerous, are easily damaged.
Model utility content
The utility model is for above-mentioned defect, and it is a kind of simple in structure that object is to provide, and has the non-dismountable cylinder valve of dimethyl ether of good non-dismountable property.
The technical solution adopted in the utility model is for this reason: the utility model comprises valve body (1), is disposed with from top to bottom valve (2), presses female (5), back-up ring (6) in valve body (1), in valve body (1), from above-mentioned parts, wears and valve rod (3) excessively; Described valve (2) drives by valve rod (3) opening and closing of stroke to cylinder valve that move up and down, described valve rod (3) bottom is protruded a circumferential step and is blocked this boss by female (5) lower end of described pressure, and valve body (1) upper end is provided with closing in portion by described back-up ring (6) restriction within it.
Described valve rod (3) is connected with valve (2) by an axle, and valve (2) is threaded in valve body (1).
Between described valve rod (3) and pressure female (5), adopt axis hole to connect, press female (5) to be threaded connection in valve body (1).
Between described pressure female (5) and valve rod (3), establish Sealing (4).
The utility model has the advantages that: the utility model is simple in structure, component are less, but owing to having adopted twice measure, one is pressed female stopping, the employing of closing up in its two valve bodies top, thus reached the non-dismountable property of cylinder valve; It compares traditional structural type, and its manufacture cost, assembly cost all greatly reduce, and have good non-dismountable property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that valve body, 2 is that valve, 3 is that valve rod, 4 is that Sealing, 5 is back-up ring for pressing mother, 6.
Embodiment
The utility model comprises valve body 1, is disposed with from top to bottom valve 2, presses mother 5, back-up ring 6 in valve body 1, in valve body 1, from above-mentioned parts, wears and valve rod 3 excessively; Described valve 2 drives by valve rod 3 opening and closing of stroke to cylinder valve that move up and down, and described valve rod 3 bottoms are protruded a circumferential step and blocked this boss by female 5 lower ends of described pressure, and valve body 1 upper end is provided with closing in portion by described back-up ring 6 restrictions within it.
Described valve rod 3 is connected with valve 2 by an axle, and valve 2 is threaded in valve body 1.
Between described valve rod 3 and pressure female 5, adopt axis hole to connect, press female 5 to be threaded connection in valve body 1.
Between described pressure female 5 and valve rod 3, establish Sealing 4.
The utility model, when normal use, makes valve 2 also produce rotation by valve rod 3 rotations simultaneously, because valve 2 and valve body 1 are to be threaded, so valve 2 in valve body 1 inside, move up and down, the opening and closing of the existing cylinder valve of historical facts or anecdotes.
Because valve rod 3 is that axle is connected with hole with pressing mother 5, under the impact without valve 2, rotary valve rod 3 can not produce the trend moving upward.
When unauthorised opening cylinder valve arrives maximum Lift, between valve 2 and valve rod 3, can produce friction, can make valve rod 3 have the trend moving upward, because pressing mother 5 and valve body 1, be to be threaded connection, in the time of fixedly, adopted special tool to apply certain pretightening force, this pretightening force is far longer than between shutter member 2 and valve rod 3 and produces friction, the trend that has stoped valve rod 3 to move upward, riveting closing in has been carried out in valve body 1 end simultaneously, thereby further stoped the arbitrarily possibility of demolition of valve body 1 inner components, therefore make the utility model cylinder valve, safety is reliable again.
Claims (4)
1. the non-dismountable cylinder valve of dimethyl ether, is characterized in that, comprises valve body (1), is disposed with from top to bottom valve (2), presses female (5), back-up ring (6) in valve body (1), in valve body (1), from above-mentioned parts, wears and valve rod (3) excessively; Described valve (2) drives by valve rod (3) opening and closing of stroke to cylinder valve that move up and down, described valve rod (3) bottom is protruded a circumferential step and is blocked this boss by female (5) lower end of described pressure, and valve body (1) upper end is provided with closing in portion by described back-up ring (6) restriction within it.
