Abstract
A bottle valve comprises an upper valve body and a lower valve body which are connected through a thread. A spring is arranged in each valve body. A ball body is arranged at one end of each spring. A rubber sealing ring is arranged between each spring and an air inlet. The bottle valve is simple in structure and convenient to manufacture, and opening and closing of the valve can be conveniently controlled by tightening and loosening of the thread.
Description
Technical field
The utility model relates to a kind of valve, particularly is installed in the valve on the gas cylinder.
Background technique
At present, the valve that is used on gas cylinder is varied, and the characteristics that generally have are complex structures, and size is large, causes therefrom valve operation inconvenience, and the opening and closing control of valve is insensitive.
The model utility content
In order to overcome the operation that valve mechanism is complicated, size is brought the greatly inconvenience on the existing gas cylinder and to control insensitive deficiency, the utility model provides a kind of cylinder valve, and this cylinder valve is simple in structure, manual dexterity.
The technological scheme that its technical problem that solves the utility model adopts is: cylinder valve comprises upper valve body and lower valve body, upper valve body links to each other by screw thread with lower valve body, form cavity between upper valve body and the lower valve body, lower valve body is provided with inlet hole, the cavity that is positioned at air inlet position is provided with rubber seal, upper valve body is provided with some air outlet holes, and a spring is positioned at cavity and is fixedly linked with upper valve body, and the other end of spring links to each other with spheroid.
Working procedure of the present utility model is, with an end with the spring fitting of spheroid in upper valve body, lower valve body is linked to each other by screw thread with upper valve body, when the screw thread bound fraction is larger, spring in the upper valve body promotes spheroid and is pressing rubber seal, realizes the function that cylinder valve is closed; When the screw thread bound fraction was less, spring left rubber seal with spheroid, and inlet hole and the air outlet hole of cylinder valve are connected.
The beneficial effects of the utility model are, cylinder valve simple in structure, and convenient the manufacturing is by the easily opening and closing of control valve of degree of tightness of screw thread.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. upper valve bodies among the figure 2. descend valve body, 3. screw thread, 4. cavity, 5. inlet hole, 6. rubber seal, 7. air outlet hole, 8. spring, 9. spheroid.
Embodiment
In Fig. 1, cylinder valve comprises upper valve body 1 and lower valve body 2, upper valve body 1 links to each other by screw thread 3 with lower valve body 2, form cavity 4 between upper valve body 1 and the lower valve body 2, lower valve body 2 is provided with inlet hole 5, and the cavity 4 that is positioned at inlet hole 5 places is provided with rubber seal 6, and upper valve body 1 is provided with some air outlet holes 7, one spring 8 is positioned at cavity 4 and is fixedly linked with upper valve body 1, and the other end of spring 8 links to each other with spheroid 9.
