Valve member of the present utility model, owing to be provided with water conservancy diversion cover and end cap, the inside of water conservancy diversion cover is provided with the little guide channel in big centre, two ends, therefore both can also can be used as vacuum pumping device, one many usefulness, economical with materials and cost as inflation, means of deflation.
The charge gun that the utility model provides, owing to adopt valve member of the present utility model as aerating and exhaust device and vacuum pumping device, and need not establish a vacuum pumping device in addition, the purpose that can be embodied as pressurized container inflation, venting, pressure measurement, vacuumizes, easy to use, high working efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model valve member one preferred embodiment;
Fig. 2 is the structural representation that is provided with the charge gun of valve member among Fig. 1.
Embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to shown in Figure 1, valve member of the present utility model comprises water conservancy diversion cover 1, end cap 2, sealing gasket 3, nozzle 4.
Wherein, the outlet end of water conservancy diversion cover 1 is provided with outside thread, and an end of end cap 2 openings is provided with internal thread, and end cap 2 and water conservancy diversion cover 1 link together by internal and external threads.
Wherein, be provided with guide channel 11 in the water conservancy diversion cover 1, the bore at described guide channel 11 two ends is greater than the bore at middle part, and its end is cone cylinder body shape.
Wherein, the sidewall of end cap 2 is provided with through hole 21, as venting.
Wherein, nozzle 4 inside are provided with air flue 41, and the air flue bore of close inlet end is greater than the air flue bore near the outlet side.The outside, outlet side of nozzle 4 is cone cylinder body shape, and the outside dimensions of this outlet side is less than the Inner Dimension of the entrance point of guide channel, and in use, the entrance point of water conservancy diversion cover can partly be stretched in this outlet side.
Valve member of the present utility model has simple in structure, and is easy for installation, cheap, maneuverable advantage.It not only can be applicable at tire and charges and discharge on the gas, can also be used in the pipeline of other non-pneumatic flowing mediums as rise by and the parts of opening function.
Referring to Fig. 2, charge gun of the present utility model comprises the valve member that the utility model provides: water conservancy diversion cover 1, end cap 2, sealing gasket 3, nozzle 4 also comprise the main body 5 that is provided with main airway, as the plate machine 6 of air flue switch and valve float 7, spool thimble 8, pressure gauge 9, air outlet adapter 10, capping 11, air input joint assembly 12.
Wherein, described air outlet adapter 10 is connected with the outlet side of described main body 5.Described air input joint assembly 12 is connected with the inlet end of described main body 5.Described valve member is arranged in the main airway of described main body 5.The outlet end of described water conservancy diversion cover 1 stretches out main body 5 outsides, overlaps the end cap 2 that 1 outlet end is connected with described water conservancy diversion and also is arranged on main body 5 outsides; The entrance point of described water conservancy diversion cover 1 stretches into main body 5 inside; Described nozzle 4 is arranged at main body 5 inside, and the outlet side part of nozzle 4 extend in the entrance point of water conservancy diversion cover 1.
