Abstract
The utility model discloses a one-way air gun valve which comprises a valve body and a valve core connected with the valve body. An inflation hole is formed in the valve core, a valve core air inflation/deflation port communicated with the inflation hole is formed in the valve core, a sealing ring I and a sealing ring II are arranged on the valve core, the valve core air inflation/deflation port is located between the sealing ring I and the sealing ring II, the bottom face of the valve core is provided with a valve core bottom face air inflation/deflation port, and the bottom end of the valve core is connected with a spring. After the one-way air gun valve is used for performing inflation on a device, automatic pressure maintaining is automatically achieved under the effect of the spring. When the inflated device is required to be subjected to deflation, a deflation function can be achieved by manually pressing the valve core. In addition, the one-way air gun valve is simple in structure, small in size and low in cost.
Description
Technical field
The utility model belongs to compressed air technique field, relates to a kind of unidirectional air gun valve.
Background technique
Unidirectional air gun valve is mainly used in a certain parts to inflate, but after being used to complete, these parts need to release gas, existing unidirectional air gun valve is disappointing function mostly, and, complex structure, expensive large with the volume of the unidirectional air gun valve of the function of losing heart are not suitable in less space or require the occasion that cost performance is high to use.
Model utility content
The purpose of this utility model is to provide a kind of unidirectional air gun valve, and the volume that solved the existing unidirectional air gun valve with the function of losing heart is large, complex structure, expensive problem.
The technological scheme that the utility model adopts is, unidirectional air gun valve, comprise valve body and the spool being connected with valve body, in spool, be provided with air-filled pore, spool is provided with the spool air inlet/leakage port being communicated with air-filled pore, and spool is provided with seal ring I and seal ring II, and spool air inlet/leakage port is between seal ring I and seal ring II, spool bottom surface is provided with enter/leakage port of spool bottom surface, and spool bottom is connected with spring.
Feature of the present utility model is also,
Valve body and spool Spielpassung.
Spool low side is provided with valve core spring and dodges hole, and spring is positioned at valve core spring and dodges hole.
The beneficial effects of the utility model are that the unidirectional air gun valve of the utility model after a certain device is inflated, is realized automatic pressure-maintaining under the effect of spring; In the time being inflated device and need to losing heart, Manual press spool can be realized disappointing function; And it is simple in structure, volume is little, and cost is low.
Brief description of the drawings
Fig. 1 is the structural drawing of the unidirectional air gun valve of the utility model;
Fig. 2 is the sectional drawing of the unidirectional air gun valve inflation of the utility model or air deflating state;
Fig. 3 is the sectional drawing of the unidirectional air gun valve of the utility model packing state.
In figure, 1. valve body, 2. air-filled pore, 3. seal ring I, 4. seal ring II, 5. spring, 6. enter/leakage port of matrix, 7. spool air inlet/leakage port, 8. spool are installed, 9. matrix is installed, 10. enter/leakage port of spool bottom surface, 11. valve core springs are dodged hole, and 12. install matrix dodges hole, A. spool stop surface, B. installs matrix stop surface.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The unidirectional air gun valve of the utility model, referring to accompanying drawing 1, comprise valve body 1 and the spool 8 being connected with valve body 1, valve body 1 and spool 8 Spielpassung, in spool 8, be provided with air-filled pore 2, spool 8 is provided with the spool air inlet/leakage port 7 being communicated with air-filled pore 2, spool 8 is provided with seal ring I3 and seal ring II4, spool air inlet/leakage port 7 is between seal ring I3 and seal ring II4, spool 8 bottom surfaces are provided with enter/leakage port of spool bottom surface 10, spool 8 bottoms are connected with spring 5, the low side of spool 8 is provided with valve core spring and dodges hole 11, avoid spring to be fully compressed and to cause spring to damage in the time of compression, spring 5 is positioned at valve core spring and dodges hole 11.
The working procedure of the unidirectional air gun valve of the utility model is: need to inflate time, as shown in Figure 2, unidirectional the utility model air gun valve by being installed, matrix 9 is arranged on the device that needs inflation, by the pneumatic head of air gun or other devices is pressed into air-filled pore 2, make spring 5 in compressive state, now spool stop surface A and installation matrix stop surface B laminating, gas enters spool air inlet/leakage port 7 by air-filled pore 2, then enter enter/leakage port of spool bottom surface 10, finally by being installed, enter/leakage port of matrix 6 is filled with in the device that needs inflation, as shown in Figure 3, when pressurize, the inflation inlet of air gun or other devices is left to air-filled pore 2, now under the effect of spring force, spool 8 is return, seal ring II4 contacts with valve body 1, gas is just sealed in the device that needs inflation, while needing to lose heart after device is used to complete, promote spool 8, make spring 5 in compressive state, enter/leakage port of spool bottom surface 10 is communicated with spool air inlet/leakage port 7, gas by enter/leakage port of matrix 6, enter/leakage port of spool bottom surface 10, enter/leakage port of spool bottom surface 7 are installed, is finally released by air-filled pore 2 successively.
Installation matrix 9 need arrange an installation matrix and dodge hole 12; this installation matrix dodge hole 12 need meet spool stop surface A and matrix stop surface B laminating is installed time spring 5 be not fully compressed; in the time that spool 8 returns to packing state, spring 5 need also have certain decrement, can protect like this spring 5 phenomenon that can also not leak air in the time of pressurize.
The unidirectional air gun valve of the utility model after a certain device is inflated, is realized automatic pressure-maintaining under the effect of spring 5; In the time being inflated device and need to losing heart, Manual press spool 8 can be realized disappointing function; And it is simple in structure, volume is little, and cost is low.
