Description
Technical field
The utility model is related to a kind of explosion-proof water meter.
Background technology
Running water is that the main of nowadays people is originated with water, is still manufactured in either usually living, from each
Ordinary people be unable to do without the use of running water to all trades and professions every household.China mainly still uses mechanical water meter at present
The tonnage of people's life production and application running water is measured, however it is most using relatively broad various mechanical water meters at present
Using the table cover of single-glass material, under arctic weather especially under the big environment of temperature change, because of instrument board and list
Ponding between layer glass table cover freezes, and instrument board internal pressure increases after volume increase after icing, causes single-glass table cover to rupture
Or even situations such as pipe leakage, not only cause the waste of resource to also add hand labor burden.
The content of the invention
The purpose of this utility model is that a kind of simple in construction, structural strength of offer is high, production cost is low, in extreme environment
Under be difficult explosion explosion-proof water meter.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of explosion-proof water meter, including it is transparent
Table cover, instrument board, watchcase, described table cover are connected on above lower stop piece including that can cover lower stop piece, lid that envelope is acted on instrument board
Hollow hat type on cover, the hollow cavity for setting and forming into a sealing is enclosed by top surface on the hollow wall and lower stop piece that are covered on hat type,
Filled with transparent gases at high pressure in described sealing hollow cavity；When the increase of instrument board internal pressure, lower stop piece bottom surface is pressurized, under
Catch overcomes pressure and itself tensile strength reversible elastic deformation in hollow cavity, and lower stop piece is convex up towards hollow cavity direction
Rise, transparent gases at high pressure are squeezed transmission pressure in being covered on hat type on lid hollow cavity top surface inwall, hat type in hollow cavity
Top surface raises up deformation in cavity body, so that realize that instrument board internal pressure relief is explosion-proof, when being no longer pressurized inside instrument board,
In hollow cavity in the presence of transparent gases at high pressure, lower stop piece elastic deformation restPoses, lid hollow cavity top on hat type
Face resilience recovers to original position.
Hat type top cap of the utility model using lower stop piece and with cavity connects to form hollow cavity, and in hollow cavity
The table cover of the transparent gases at high pressure formation integrated explosion proof system water meter with cushioning effect is inside filled with, compared to the individual layer glass in conventional art
Glass table cover is at low temperature because the ponding between instrument board and table cover freezes volume and increased suddenly, and the structure of single-glass table cover is strong
Degree is ruptured far from the ice cube for supporting volume increase, water meter explosion is endured cold, the lower stop piece energy root used in the utility model
Increase according to ponding icing volume or reduce situation to the hollow cavity internal projection of table cover or resilience, the transparent high pressure in table cover
Gas itself pressure after volume-diminished becomes greatly or volume becomes itself big rear pressure and diminished, and serves buffering ponding icing volume
The effect of the larger pressure to overall table cover produced after cataclysm, makes table cover not burst because that can not bear larger pressure,
So as to reduce the phenomenon that table cover bursts under extreme temperature, the repairing maintenance work for repairing the staff for safeguarding water meter, section are reduced
About a large amount of manpower and materials, reduce the leakage and waste of running water, it is ensured that resident is normal using originally in the case of extreme temperature
Water, also provides enterprise for running water and retrieves a large amount of losses.
Further, cover by hollow circuit cylinder cap body, be integrally formed in hollow circuit cylinder cap body periphery on the hat type of the table cover
Lid is sealingly engaged by shade with lower stop piece on edge and the shade composition stretched out, hat type.Covered on the hat type of sealing engagement
Shade and lower stop piece make the transparent gases at high pressure in hollow cavity be difficult to overflow from the gap of sealing engagement, it is ensured that transparent height
Calm the anger the pressure relief capability of body.
Further, table cover is fixed on instrument board by a hubbed flange between described table cover and watchcase,
Hollow circuit cylinder cap body set, which is stretched, to be limited in the eck of hubbed flange, and the upper top surface of hollow circuit cylinder cap body is exposed to hubbed flange
Table cover is fixed in instrument board by eck, hubbed flange by its shoulder inwall to the shade suppressing action covered on table cover hat type
On.The spacing cooperation of the eck of hollow circuit cylinder cap body and hubbed flange make hollow circuit cylinder cap body will not flange eck because itself
Vibrations collide and rubbed with flange, reduce the abrasion of overall table cover, it is ensured that its energy long-time stable work, hubbed flange will
Table cover is pressed abd fixed on the overall table cover of order on instrument board and stably can be operated on instrument board.
Further, the transparent resin material for being same intensity with lower stop piece is covered on described hat type to process.Use
Lid is difficult to because material is different with lower stop piece after machine-shaping on the hat type of the transparent resin material machine-shaping of intensity of the same race
And occur because prolonged use material aging to deform or even ftracture, performance is more preferable in use.
Further, it is more than lower stop piece in the thickness that top surface is covered on the hat type of hollow cavity position in described table cover
Thickness.The thickness of top surface is covered on hat type ensures lower stop piece during occurring compared with large deformation more than the thickness of lower stop piece, cap
Although being covered in formula, top surface can still be deformed upon but deformation is not too large, prevent in lower stop piece deformation process Gai Yin on overall hat type
Ruptured for deformation is excessive, cause its performance to decline.
Further, described lower stop piece is lower concave arc piece.
Further, ultrasonic bonding is passed through between lid and lower stop piece on described hat type.After ultrasonic bonding processing,
Lid and lower stop piece are thoroughly bonded to one on hat type, in use more firm and durable, while further ensuring that middle cavity
Transparent gases at high pressure in body will not reduce the performance of table cover from being spilt on hat type in the connection gap of lid and lower stop piece.
The beneficial effects of the utility model are：Because the deformation of upper lid lower stop piece reduces instrument board internal pressure, let out so as to reach
Explosion prevention function is pressed, simultaneously because when the relation of transparent gases at high pressure makes the recovery of instrument board internal pressure normal, upper lid can recover as before, and
Reset rapidly, compared to single-glass water meter cover in the prior art, superstructure advantages of simple of the present utility model is pressure-resistant wear-resisting
Damage, stability is high, technique is simply easily achieved, it is high to observe perspectivity, the especially life-span is very long.
