Detailed description of the invention
nullAs shown in figures 1 and 3，The driving air valve of ease of assembly of the present utility model，Including valve body 1、Magnet core assembly promotes ring 9 with the external magnet being arranged on outside valve body 1，This valve body 1 be by a material idiosome be fabricated by non-by magnetic part，As shown in Figure 4，This embodiment forms in valve body 1 and is interconnected successively and inlet chamber 11 that internal diameter is sequentially reduced、Valve pocket 12、Open spring cavity 13 and escape pipe 14，Wherein Magnet core assembly includes pad 3、Return spring 4、Spool Magnet 6、Sealing-plug 7 and unlatching spring 8，Open spring 8 to be connected with sealing-plug 7，Open spring 8 to be arranged in unlatching spring cavity 13，Sealing-plug 7 and spool Magnet 6 are arranged in valve pocket 12，Pad 3 is arranged in inlet chamber 11，Return spring 4 is placed between pad 3 and spool Magnet 6，Magnet core assembly is fixed in valve body 1 by the lock-connecting piece 2 of with inlet chamber 11 phase interlocking.
As in figure 2 it is shown, the interstitial hole of the pad 3 of this embodiment is provided with drainage screen 31, thus eliminates and drainage screen accessory is additionally set, make this pad 3 can play fixation, can play a role in filtering again.The Magnet core assembly of this embodiment also includes spring base 5, and this spring base 5 is provided with stub end and little head end, and the stub end of spring base 5 is positioned at inlet chamber 11, and little head end stretches in valve pocket 12, and return spring 4 is placed between spring base 5 and pad 3.The lock-connecting piece 2 of this embodiment is jump ring 2, this jump ring 2 is the torus of an opening, corresponding is provided with groove 10 in the cavity wall of inlet chamber 11, it is made after shrinking, to put into inlet chamber 11 by pinching jump ring 2, inwardly fill in groove 10, now jump ring 2 elastic return and be partly sunken in groove 10 realize Magnet core assembly is fixed in valve body 1, as shown in Figure 3.
The air valve of this embodiment uses permanent magnet push-type air valve, and when external magnet promotes ring 9 to push opening end, spool Magnet 6 departs from the pressure of the top to sealing-plug 7, and sealing-plug 7 leaves outlet port, as shown in Figure 3 under the spring return opening spring 8；When external magnet promotes ring 9 to push shutdown side, spool Magnet 6 promotes sealing-plug 7, makes sealing-plug 7 block outlet port, and now unlatching spring 8 is extruded and is in compressive state.As shown in Figure 3, overtemperature spring 15 it is additionally provided with on the air valve of this embodiment, this overtemperature spring 15 is arranged on outside valve body 1 outside being positioned at external magnet promotion ring 9, the i.e. side of outgassing direction, this overtemperature spring 15 under normal circumstances by quick solder or meltable plastic clip dwelling in compressive state, and when being in the condition of high temperature, when solder or plastics melt, overtemperature spring 15 is released, under its elastic force effect can be external magnet promote ring 9 to inner slide so that outlet port blocked by sealing-plug 7, it is ensured that safety.Owing to needing to install after being compressed by overtemperature spring 15 when mounted, installation process easily occurs the situation that overtemperature spring 15 is ejected, bigger inconvenience is caused to installing, therefore in order to improve installation effectiveness, fix with glue after the most first overtemperature spring 15 being compressed, the glue that can dissolve or lose viscosity in high temperature environments selected by glue, install again etc. after fixing, though adding one procedure, but still substantially increase work efficiency, the most also can avoid the problem that solder or ageing of plastics overtemperature spring 15 eject.
Although this utility model is to be described with reference to specific embodiments, but this description is not meant to be construed as limiting this utility model.With reference to description of the present utility model, other changes of the disclosed embodiments, for those skilled in the art be all it is anticipated that, this change should belong in appended claims limited range.
