Abstract
The invention discloses a metal drain shielding valve, comprises a valve body on which a plurality of drain holes are arranged around the axis. The invention also provides a shielding casing, wherein the shielding casing is welded with the metal drain shielding valve two ends of which can be installed water inlet pipe or water outlet pipe respectively, and the number of the metal drain shielding valve welded on the shielding casing. The metal drain shielding valve comprises a valve body, and a plurality of drain holes arranged around the axis on the valve body. Compared with the prior common draining pipes, the metal drain shielding valve has a plurality of drain holes with small hole diameter which is smaller than the diameter of a air-filled cutoff waveguide, therefore according to the theory of cutoff waveguide, electromagnetic wave is difficult to leak along the water flow from the drain holes with small hole diameter, moreover, in the case of no water flow, the metal drain shielding valve has shielding effect of cutoff waveguide. So the invention improves shielding effect and reduces pollution to surrounding environment.
Description
Technical field
The present invention relates to a kind of metal drain shielding valve and the shield shell that this metal drain shielding valve is installed.
Background technique
Use in the device 1 of shield shell at accelerator, sterilization washing machine etc., need make water pipe 2 will install interior water and discharge.Figure 1 shows that the structural representation of existing a kind of water pipe.As shown in Figure 1, the structure of this water pipe 2 is the same with common water pipe, is the hollow straight-tube shape.This makes that when draining the electromagnetic wave in the device 1 is easy to leak into the outside by the water pipe 2 of hollow straight-tube shape.Therefore, this water pipe 2 can not shield electromagnetic wave well, has a strong impact on shield effectiveness, can pollute surrounding environment.
Summary of the invention
Therefore, the present invention aims to provide a kind of water discharging valve with good shield effectiveness.
The invention provides a kind of metal drain shielding valve, comprise valve body, wherein, on described valve body, offer a plurality of weep holes around axis.
The present invention also provides a kind of shield shell, wherein welds this metal drain shielding valve on this shield shell, and the two ends of metal drain shielding valve can be installed into water pipe or outlet pipe respectively, and the metal drain shielding valve number of being welded on the shield shell is not limit.This metal drain shielding valve comprises valve body, and on described valve body, offers a plurality of weep holes around axis.
Compare with existing normal discharge pipe, because metal drain shielding valve of the present invention only has the weep hole of a plurality of small apertures, the diameter in this aperture is also littler than the diameter of fills with air cut-off waveguide, therefore according to the cut-off waveguide theory, electromagnetic wave is difficult to the weep hole from these small apertures, along with current leak into the outside; And, also have the shielding action of cut-off waveguide during no flowing water.Therefore, improved shield effectiveness, reduced pollution surrounding environment.
Description of drawings
Fig. 1 is a kind of structural representation of existing water pipe;
Fig. 2 is the schematic representation of metal drain shielding valve of the present invention;
Fig. 3 is the cross-sectional view of the metal drain shielding valve of Fig. 2;
Fig. 4 is embodiment's the schematic representation that the shield shell of metal drain shielding valve of the present invention is installed.
Embodiment
Fig. 2-3 shows the embodiment of metal drain shielding valve of the present invention.Fig. 2 is the schematic representation of the structure of metal drain shielding valve of the present invention; Fig. 3 is the cross-sectional view of the drain shielding valve of present embodiment.
As Fig. 2, shown in 3, metal drain shielding valve 3 comprises valve body 4, on valve body 4, offers a plurality of weep holes 5 along axis, and a plurality of weep holes 5 longitudinally run through valve body 4.
Particularly, valve body 4 is a straight circular cylinder type, and a plurality of weep holes 5 evenly distribute around valve body 4 centers of straight circular cylinder type.Note that a plurality of weep holes 5 also can distribute unevenly.
Particularly, the diameter of each weep hole 5 is much smaller than the diameter of valve body 4.
Particularly, a plurality of weep holes 5 are the straight line type through hole, that is, the longitudinal axis of each weep hole 5 in line.Although Fig. 2-3 shows that valve body 4 is provided with 8 weep holes, the number of weep hole is not limited to 8, also can be more than 8 or 2-7.
Because metal drain shielding valve 3 of the present invention has the weep hole 5 of a plurality of small apertures, so electromagnetic wave is difficult to leak into the outside from the weep hole 5 of these small apertures, improved shield effectiveness, reduced the pollution to surrounding environment.
Fig. 4 is the schematic representation that the radiation device shield shell of metal drain shielding valve of the present invention is installed.
As shown in Figure 4, can directly metal drain shielding valve 3 of the present invention be installed on the radiation device shield shell 1.
Particularly, radiation device shield shell 1 can be any electronics of electromagnetic radiation, shield shells of electrical equipment of existing such as accelerator, sterilization washing machine.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can change that scope of the present invention is limited by claims and equivalent thereof to these embodiments.
