Abstract
The utility model relates to a spool of a double-steady state electromagnetic valve, which changes the structure that a spool of an existing electromagnetic valve product is solid (or essentially is solid only with a small spring seat hole); the utility model is processed into a large hollow form. The ratio of the capacity of the inner hole and the valume of an outer column is larger than 0.4. The utility model provides a spool structure of an electromagnetic valve; when the electromagnetic valve works under the somewhat low voltage (such as 3V and 6V), the stability thereof is high, (namely the stability thereof is obviously increased compared with an existing product with the same functions in the opening and the closting states).
Description
The utility model relates to a kind of bistable electromagnetic valve, relates in particular to the valve core structure of bistable electromagnetic valve.
After 1985 " bistable electromagnetic valve " (patent No. 85201056) patent disclosure, only China has some patents that are called " impulse electromagnetic valve " to occur again.Because this series products has extreme power saving, electricity consumption or not of retention time during valve work, thus it has almost occupied the market that " card water meter " " cassette gas meter " and " automatic faucet " etc. rely on the powered battery product.
In various occasions, especially in the design of cassette water (gas) table product, reliability of products is the first element.Because of most of user knows nothing performance, the characteristics of product, product is placed within doors in addition, and the maintenance overhaul maintenance is also very inconvenient.Have metering because of this product has by cutting off water, combustion gas etc. in addition, charge, call function such as expense, so also need to solve artificial water (gas) problem of stealing that prevents, i.e. the design of anti-attack.And the consideration of existing product this respect is not enough, and impact resistance is poor, so the poor reliability of product use.
In the existing product, not only require card, computer aspect fully to overcome one's shortcomings, more require the serious problems of the poor stability of solution solenoid valve.
The purpose of this utility model is: a kind of electromagnetic valve core structure is provided, and when solenoid valve uses low voltage (as 3V, 6V) work, the solenoid valve of its stability high (promptly no matter obviously improving) at the existing congenerous product of its stability of the state of opening and closing.
The purpose of this utility model is achieved in that
1. change in the existing solenoid valve product spool and be real core (or be real core basically--have only one very little
Spring base hole) structure is processed into the form of hollow largely.Interior pore volume/outer cylinder volume
Ratio be greater than 0.4.
2. pod apertures 2-4 is only left in the spool bottom, and the damping of fluid was promptly carried when moment, merit was done with the reduction spool
Channel Group's path for the water (gas) of handling up.
Characteristics of the present utility model are: after adopting above-mentioned design, the time that not only opens and closes solenoid valve shortens, and operating voltage also has corresponding reduction, has reached the effect of economize on electricity, more because the weight of spool alleviates greatly, has improved stability, the reliability of product greatly.Utilize the product of this solenoid valve to be designed to the very capable product of water-stealing-preventing (gas) easily.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a structural representation of the present utility model
As shown in the figure, be user's water meter (TM card system) design, nominal size is 6 " bistable state control water solenoid valve spool schematic representation.
Spool places in the conduit, and the spool conduit is the stainless steel drawn tube, and spool places in it, and spool 1 external diameter is that φ 9.2+0.05mm endoporus aperture is φ 7.6mm, and the spool bottom is drilled with the inclined hole 2 of 4 φ 2.5mm in order to water conservancy diversion.
The hollow ratio of this spool is:
The interior pore volume of column part (bottom inclined hole and disregard below the tapered segment)/outer cylinder volume ratio: promptly φ=V content/V outer=(7.6/9.2)
2=0.682, and contrast Israel Related product hollow is 0.013 than only.
Actual measurement confirms, product after the improvement, because spool weight saving, inertia diminishes, water resistance reduced greatly when spool was up in addition, thereby its stability greatly improves, and shock resistance is promptly for resisting in going in poppet shaft to knocking, the resistivity of endeavouring of shaking has improved several times than existing product, can be used for cassette water (gas) table safely.
Claims (3)
1. a bistable electromagnetic valve core is characterized in that spool in the solenoid valve (1) is processed into the form of hollow.
2. by the described bistable electromagnetic valve core of claim 1, it is characterized in that the spool bottom only leaves pod apertures 2-4.
3. by claim 1,2 described bistable electromagnetic valve cores, the ratio that it is characterized in that pore volume in it/outer cylinder volume is greater than 0.4.
