Abstract
The utility model relates to a water gauge field of making, concretely relates to piston volumetric water meter, include watchcase down, the watchcase is connected with metering mechanism down, the last water strainer that is equipped with of metering mechanism, metering mechanism connects the piston, hinge joint has the apron subassembly, the counting mechanism is connected to the apron subassembly, the counting mechanism is connected with drive mechanism, the watchcase is connected with the watchcase down, be equipped with the takeover on going up the watchcase, when rivers pass through the water gauge, the water flow drive piston was rotatory with novel this moment, and the volume of piston cylinder is invariable, so record the rotatory number of times of piston through the counting mechanism, can learn the water yield that flows through the water gauge, and the piston volumetric water meter measuring is the volume through the real fluid of water gauge, so piston volumetric water meter measuring ten minutes accuracy.
Description
Technical field
This utility model relates to water meter and manufactures field, is specifically related to a kind of piston positive-displacement water meter.
Background technology
Water meter is a kind of common articles for use in daily life, China's publication number is a kind of water meter of CN203287072U, by water meter body, water meter copper cover, instrumental panel and table cover composition, water meter copper cover is connected with water meter body by some screws, the bottom surface of described water meter copper cover is provided with the pin of some inverted cones protruded down, the end face of water meter body offers the jack of some recessed inverted cones and mates with described pin, described pin and the spaced arrangement of through hole on water meter copper cover, described jack and the spaced arrangement of screwed hole on water meter body, but this do not have counting mechanism and record piston number of revolutions, so what measure is not exactly accurate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of measures piston positive-displacement water meter accurate, easy and simple to handle.
This utility model provides techniques below scheme: a kind of piston positive-displacement water meter, including lower watchcase, described lower watchcase is connected to metrological service, described metrological service is provided with water strainer, and described metrological service connects piston, and described piston is connected to cover plate assembly, described cover plate assembly connection count mechanism, described counting mechanism is connected to drive mechanism, and described lower watchcase is connected to watchcase, and described upper watchcase is provided with adapter.
On such scheme basis preferably, described adapter is provided with adapter seal washer, and they are connected by attaching nut.
On such scheme basis preferably, the end of described adapter is provided with dirt-proof boot.
On such scheme basis preferably, described upper watchcase is provided with copper pin.
On such scheme basis preferably, described upper watchcase is casting pig with the material of lower watchcase.
On such scheme basis preferably, described counting mechanism is connected by clamp system with drive mechanism.
This utility model compared with prior art have the beneficial effect that now with novel when current by water meter time, current drive piston to rotate, and the volume of piston cylinder is constant, so recording piston number of revolutions by counting mechanism, namely would know that the water yield flowing through water meter, what piston positive-displacement water meter was measured is the volume of the real fluid through water meter, so piston positive-displacement water meter measurement is exactly accurate; Adapter is provided with adapter seal washer, and they are connected by attaching nut, adapter seal washer plays the effect sealing adapter, facilitates dismounting and change by the connected mode of attaching nut, and the end of adapter is provided with dirt-proof boot, prevent in dust entrance table body, causing fault, upper watchcase is provided with copper pin, it is prevented that installation site, direction mistake, the material of upper watchcase and lower watchcase is casting pig, comprcssive strength and have higher intensity, hardness and wear resistance.
Accompanying drawing explanation
Fig. 1 is that this utility model overall structure launches schematic diagram.
Number in the figure is: watchcase under 1-, 2-metrological service, 3-water strainer, 4-piston, 5-cover plate assembly, 6-counting structure, 7-drive mechanism, the upper watchcase of 8-, and 9-takes over, and 10-adapter seal washer, 11-attaching nut, 12-dirt-proof boot, 13-copper pin, 14-adds locking structure.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Known with reference to Fig. 1, a kind of piston positive-displacement water meter, including lower watchcase 1, described lower watchcase 1 is connected to metrological service 2, and described metrological service 2 is provided with water strainer 3, described metrological service 1 connects piston 4, described piston 4 is connected to cover plate assembly 5, described cover plate assembly 5 connection count mechanism 6, and described counting mechanism 6 is connected to drive mechanism 7, described lower watchcase 1 is connected to watchcase 8, and described upper watchcase 8 is provided with adapter 9.
Further, described adapter 9 is provided with adapter seal washer 10, and they are connected by attaching nut 11, and adapter seal washer 10 plays the effect sealing adapter, facilitates dismounting and change by the connected mode of attaching nut 11.
Further, the end of described adapter 9 is provided with dirt-proof boot 12, it is prevented that dust enters in table body, causes fault.
Further, described upper watchcase 8 is provided with copper pin 13, it is prevented that installation site, direction mistake.
Further, the material of described upper watchcase 1 and lower watchcase 8 is casting pig, comprcssive strength and have higher intensity, hardness and wear resistance.
Further, described counting mechanism 6 is connected by clamp system 14 with drive mechanism 7.
This utility model compared with prior art have the beneficial effect that now with novel when current by water meter time, current drive piston 4 to rotate, and the volume of piston cylinder is constant, so recording piston 4 number of revolutions by counting mechanism 6, namely would know that the water yield flowing through water meter, what piston 4 volumetric water meter was measured is the volume of the real fluid through water meter, so piston positive-displacement water meter measurement is exactly accurate.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
