Abstract
The invention provides a water-supply safe water meter combination, which comprises a water meter assembly, a release water non-return device and an output water non-return device, and the water meter assembly and the shell of the device are communicated. The outlet of the water meter assembly is provided with two non-return plates, bases respectively matched with the non-return plates realize sealing and non-returning, a control chamber is arranged between the two non-return plates and is provided with a diaphragm to form a control cavity, water at the water inlet of the release water non-return device enters the control cavity via a through hole in the shell, and an externally hanging control fitting is not needed. The beneficial effect is as follows: the water-supply safe water meter combination of the structure is the water meter device which limits pressure medium in a pipeline to flow in one direction, thus meeting the metering demand and exporting backflow medium in the pipeline or medium in critical backflow in any working condition to the outside of a pipe to form air partition. The installation length and the length of a household water meter are almost identical, the device has good interchangeability with the using water meter in the family, water-supply safety can be ensured, and pollution is prevented.
Description
Technical field
The present invention relates to a kind of apparatus structure, particularly a kind of water-supply safe water table pack.
Background technology
The safety problem of present urban water supply becomes the problem of Party and government and the concern of common people's common elevation, Xi'an has just taken place because municipal administration is cut off the water suddenly, the stool and urine in lavatory, civic is sucked into the municipal water supply pipeline, when municipal administration supplies water once more, many citizen tap of fetching boiling water, flow out toilet paper and excremental great water resource pollution accident, middle water has also taken place in Tianjin, and citizen's water of flushing the toilet is back to the accident of water supply network, the community resident that has is forced to drink middle water unexpectedly for a long time, continuous with municipal water supply department contradiction, cause citizen to go to bits, water body and water supply network and equipment are impaired serious, make a very bad impression, this example is in other cities also ubiquity, so China Ministry of Construction requires all will to install the anti-backflow facility additional may producing backflow place, but in relating to citizen house for the water supply terminal of representative does not have solution all the time, countries in the world government knows the importance of this type problem perfectly well, and can't guarantee resident's water safety, make whole urban water supply bring great potential safety hazard.Because direct water receiving table after municipal water purification is registered one's residence in the general citizen family, the water meter outlet may be with regard in the directly hidden body of wall, there is not the space, will destroy body of wall as installing other equipment additional, citizen are unwilling maybe will compensate, can't coordinate, will at any time backflow pollution can take place as not adorning, innumerable because of suffering from.At this moment just need a kind of water-supply safe water table pack, need only for water meter or water meter shell can meet the demands down by function of measuring.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the present invention can reach really energy-conservation, metering by a kind of water-supply safe water table pack is provided, and is safe, anti-pollution, convenient, takes up an area of little purpose.
A kind of water-supply safe water table pack, this water-supply safe water table pack includes the water meter assembly, sluicing check device and water outlet check device, the housing of described water meter assembly and device is connected and is communicated with, it is characterized in that: described sluicing check device includes housing one (3), check plate one (4), spring one (2), check lever one (1); The check lever one (1) of described sluicing check device is arranged on the outlet of water meter assembly (15), sluicing check device housing () water inlet oral area, described check plate one (4) moves right and opens during unlatching, check plate one (4) leaves the pedestal that matches, water can pass through, and check plate one (4) is moved to the left and is close to the pedestal that matches and can realizes sealing non-return when closing; Be provided with diaphragm (12) in the sluicing check device pulpit, sealing gasket (10), cover and be fastened on the lower housing portion of sluicing check device with lower cover (13), form control chamber, the water of the water inlet of sluicing check device is by the through hole on this housing one (3) and by entering the pulpit control chamber, and the sluicing check device is with housing two (7) the fastening and connections of described water outlet check device; Described check plate two (8) moves right and opens during unlatching, and check plate two (8) leaves the pedestal that matches, and water can pass through,, check plate two (8) is moved to the left at spring two () and is close to the pedestal that matches and can realizes sealing non-return when closing; ,
Effect of the present invention is that the water-supply safe water table pack of this structure is a kind of strict metering water meter that ducted pressure medium is made uniflux that limits, it can satisfy under any operating mode and all can measure and ducted refluence medium or the medium that is in critical refluence " are led " to go out outside the pipe, guarantee water supply security, prevent to pollute.The low water head loss is guaranteed in through type, big area of passage design; The ultrashort type structure guarantees to save installing space;
Description of drawings
The cut-open view of structure when Fig. 1 normally opens for the present invention;
The cut-open view of structure when Fig. 2 sluices for the present invention normally closes.
Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated water-supply safe water meter unitized construction of the present invention.
The water-supply safe water table pack is the structure that the technical field important breakthrough is arranged.
As shown in Figure 1, arrow is represented the media flow direction among Fig. 1.A kind of water-supply safe water table pack, this water-supply safe water table pack includes the water meter assembly, sluicing check device and water outlet check device, the housing of described water meter and device is connected and is communicated with, during the water forward flow, the water meter normal rotation is measured, described check plate one (4) moves right and opens under hydraulic action, check plate one (4) leaves the pedestal that matches, check plate two (8) moves right and opens simultaneously, check plate two (8) leaves the pedestal that matches, the water of the water inlet of sluicing check device is by the through hole on this housing one (3) and by entering the pulpit epicoele, realize action when pressure water action can promote diaphragm when diaphragm (12) is gone up, pressure relief opening is closed, forward normal water supply.
As shown in Figure 2, arrow is represented the media flow direction among Fig. 2.When water-supply safe water meter combination import decompression, check plate one (4) is moved to the left is close to the pedestal that matches, check plate two (8) is moved to the left to be close to the pedestal that matches and can all to realize sealing non-return, the water of the water inlet of sluicing check device is owing to lose pressure, the water of pulpit epicoele enters water inlet by the through hole on this housing one (3), check plate one, pressure water action between the check plate two is gone up at diaphragm (12) and is promoted diaphragm realization action down downwards, open the sluicing function, thereby guaranteeing can not take place to flow backwards pollutes.
