Abstract
The utility model relates to a water meter scratch prevention counter belonging to fluid measurers. The water meter scratch prevention counter provided in the utility model is characterized in that a cylindrical groove is disposed in a surface of a transparent plastic cover, and a transparent protective layer is disposed in the groove. The utility model is advantageous in that a hard transparent protective layer is additionally disposed on the counter to protect the surface of the plastic protective cover from being scratched; the air tightness between the protective layer and the plastic protective cover can be guaranteed by a sealing ring and a fixing ring, thereby the clear indication of the surface of the plastic protective cover can be guaranteed by preventing dirt from entering the transparent protective layer from the periphery. In addition, a sealing function of the sealing ring disposed between the counter bottom and the flange cover can be used to prevent dirt from entering an inner chamber of the counter from the gap of the counter protective cover and a supporting plate, thereby the damage on a dry type counter can be prevented.
Description
Technical field
The utility model belongs to fluidic counter, especially belongs to the anti-scraping of water meter counter.
Background technology
At northern area, because cold of weather is frozen in order to prevent the water in the water pipe in winter, needing running water pipe is installed in has the underground of certain depth apart from ground.Usually can be because of reason such as raining, table WIH table counter surface is covered by dirts such as dust, sewage.And in the reading of checking meter, the meter reading personnel often stands directly on the table well limit, uses cleek to stretch in the table well, the tegillum of water meter is raised the reading of checking meter.Dirt influences reading, and the meter reading personnel is usually smoothly with cleek scraping counter surface cleaning dirt.As shown in Figure 1, it all is to adopt transparent plastic protective cover 1 that present most of magnetic pass the dry type counters, scratch-resistant not, and after a period of time, the surface just accumulates numerous scratches, causes not seeing more concrete reading.
Summary of the invention
The utility model purpose is to overcome above-mentioned shortcoming, and a kind of anti-scraping of water meter dry type counter of surperficial scratch-resistant is provided.
The technical scheme that the utility model adopted is the anti-scraping of an a kind of water meter dry type counter, and its main points are on the surface of transparent plastic protective cover a cylinder shape groove is arranged, and the layer of transparent protective layer is housed in groove.
Reach the purpose that protection plastic safety cover surface is not scratched through increasing the hard transparent protective layer of one deck.
Usually protective layer is the tempered glass sheet.Utilize the characteristic of tempered glass sheet high rigidity scratch-resistant to protect the transparent plastic protective cover not scratched.
An O RunddichtringO groove is arranged in the bottom of cylinder shape groove, place an O RunddichtringO in the groove.Through vacuumizing, make the tempered glass sheet tightly be adsorbed on the counter transparent protective shield.
On the slit at upper bond place between transparent plastic protective cover and the transparent protective layer, added a circle T RunddichtringO, and had a set collar to entangle counter, when being fixed on set collar on the blind flange, compressed the T RunddichtringO with bolt.To prevent that vacuum tightness is destroyed between tempered glass sheet and the plastic safety cover, fouls such as sewage flow into the space between glass and the plastic jacket from tempered glass sheet periphery, influence reading, play good sealing function.
On the blind flange of the joint of counter and blind flange, an annular groove is arranged; Place a rectangular seal in the groove, when set collar compresses the T RunddichtringO, be pressed on the rectangular seal under counter is stressed; Also compress rectangular seal; Play the excellent sealing effect, can prevent that sewage etc. from flowing into the counter inner chamber from the gap between counter protective cover and supporting plate, damage the dry type counter.
The utility model advantage is that reaching protection plastic safety cover surface through the hard transparent protective layer of increase one deck is not scratched; And guarantee impermeability between protective layer and the plastic safety cover through O-ring seal and set collar, in order to avoid dirt gets into the surface of plastic safety cover and influences the sharpness of reading from transparent protective layer periphery.In addition, also, prevent that dirt from flowing into the counter inner chamber from the gap between counter protective cover and supporting plate, damage the dry type counter through the sealing function of the O-ring seal between counter bottom and the blind flange.

Fig. 2 is the structural representation of the utility model
Wherein: 1 transparent plastic protective cover, 2 cylinder shape grooves, 3 O RunddichtringO grooves, 4 transparent protective layer 5 T RunddichtringOs 6 set collars 7 supporting plates 8 annular grooves 9 rectangular seals 10 blind flanges.
Concrete mode
Below in conjunction with view the utility model is carried out detailed description, cited embodiment can make the professional and technical personnel more understand the utility model, but does not limit the utility model in any form.
As shown in Figure 2, the anti-scraping of a kind of water meter counter is when transparent plastic is processed in the main body that keeps counter protective cover 1; Improve the protective cover structure; Surface design has a cylinder shape groove 2 above that, at bottom portion of groove one circle O RunddichtringO groove 3, the O RunddichtringO of in groove, packing into is arranged; Again transparent protective layer 4 is encased in the cylinder shape groove 2, generally uses circular tempering glass sheet to do transparent protective layer 4.Through vacuumizing, make transparent protective layer 4 tightly be adsorbed on the transparent plastic protective cover 1.In order to prevent that water meter is in transportation and use; The vibrations because jolt, and the effect that the variation of ambient air pressure and causing vacuumizes reduces, and between transparent plastic protective cover 1 and transparent protective layer 4, added one in the slit at upper bond place and enclosed T RunddichtringO 5; And there is a set collar 6 to entangle counter; When being pressed on the blind flange 10, compress T RunddichtringO 5, play good sealing function with bolt.On the blind flange 10 of the joint of counter and blind flange 10, an annular groove 9 is arranged; Place a rectangular seal 8 in the groove; When set collar 6 compressed T RunddichtringO 5, the stressed rectangular seal 8 that presses down of counter played the excellent sealing effect; Can prevent that sewage etc. from flowing into the counter inner chamber from the gap of transparent plastic protective cover 1 and supporting plate 7, damages the dry type counter.
