Abstract
The utility model relates to a water gauge technical field, concretely relates to positive displacement measurement water gauge, including apron and metering mechanism, apron lower extreme surface is connected with cross beam axial through the mode of viscose, the cross beam axial below is equipped with the measuring chamber, the measuring chamber is connected with the apron, the apron upper end is connected with the transmission shaft, the transmission shaft is connected with and pulls out the fork, be equipped with the bush on the transmission shaft, the bush is connected with the piston, the piston is located on the metering mechanism, being equipped with the non return cover between measuring chamber and the metering mechanism, under water pressure, in water gets into the measuring chamber, promoting the piston ring and make rotary motion around the center pin of measuring chamber, water vacancy and piston from the piston in is discharged with the vacancy flow direction upper portion delivery port that the measuring chamber wall formed simultaneously, when the piston is rotatory, be connected with the counting mechanism by the axis of rotation, so as long as write down the rotatory number of times of piston, but flow past the volume of water gauge with regard to the integrating play, the restoration is nursed one's health easily to simple and convenient operation.
Description
Technical field
This utility model relates to water meter technical field, is specifically related to a kind of volumetric metering water meter.
Background technology
Volumetric water meter is also known as piston water meter, it it is the water meter of a kind of fixed displacement formula, in national standard, volumetric water meter is defined as and " is arranged in closed conduct, gradually it is full of by some and rooms of known volume of exhaust fluid and a kind of water meter of forming by fluid-operated mechanism, volumetric water meter has rotary-piston type and the big series of disc type two, when current are by water meter, current drive piston to rotate, and the volume of piston cylinder is constant, so, piston number of revolutions is recorded by counting mechanism, namely would know that the water yield flowing through water meter, but it is complex that general volumetric water meter repairs debugging, the requirement of water quality is higher.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind of simple computation can flow through the volumetric metering water meter of water meter volume.
For solving above-mentioned technical problem, this utility model provides techniques below scheme: a kind of volumetric metering water meter, including cover plate and and metrological service, described cover plate rear surface is connected to crossbeam axle by the mode of viscose glue, described crossbeam axle is connected with measuring chamber, described measuring chamber is connected with cover plate, described cover plate upper end is connected to power transmission shaft, described power transmission shaft is connected to fork, described power transmission shaft is provided with lining, described lining is connected to piston, and described piston is located in metrological service, is provided with non-return set between described measuring chamber and metrological service.
On such scheme basis preferably, described metrological service upper end is provided with O RunddichtringO.
On such scheme basis preferably, described metrological service lower end is provided with water strainer.
This utility model compared with prior art has the beneficial effect that under hydraulic pressure effect, water enters in measuring chamber, piston ring is promoted to rotate around the central shaft of measuring chamber, the vacancy that simultaneously water is formed from vacancy in piston and piston and measuring chamber wall flows to top outlet discharge, while piston rotates, it is connected with counting mechanism with fork by rotating axle, as long as so writing down piston number of revolutions, just can calculate the volume flowing through water meter, simple and convenient operation, conditioning is repaired easily; Metrological service upper end is provided with O RunddichtringO, convenient dismounting, and metrological service lower end is provided with water strainer, for the moisture that defence area is revealed, it is prevented that affect the operation of metrological service.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Number in the figure is: 1-crossbeam axle; 2-cover plate; 3-measuring chamber; 4-rotates axle; 5-shift fork; 6-lining; 7-piston, 8-metrological service; 9-O shape sealing ring; 10-water strainer; 11-non-return set.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
Known with reference to Fig. 1, a kind of volumetric metering water meter, including cover plate 2 and metrological service 8, described cover plate 2 rear surface is connected to crossbeam axle 1 by the mode of viscose glue, described crossbeam axle 1 is connected with measuring chamber 3, described measuring chamber 3 is connected with cover plate 2, described cover plate 2 upper end is connected to power transmission shaft 4, described power transmission shaft is connected to fork 5, described power transmission shaft 4 is provided with lining 6, described lining 6 is connected to piston 7, and described piston 7 is located in metrological service 8, is provided with non-return set 11 between described measuring chamber 3 and metrological service 8.
It should be noted that described metrological service 8 upper end is provided with O RunddichtringO 9, convenient dismounting, described metrological service 8 lower end is provided with water strainer 10, for the moisture that defence area is revealed, it is prevented that affect the operation of metrological service 8.
Based on above-mentioned, under hydraulic pressure effect, water enters in measuring chamber 3, promotes piston 7 to rotate around the central shaft of measuring chamber 3, and water flows to top outlet from the vacancy that vacancy in piston 7 and piston 7 and measuring chamber 3 wall are formed and discharges simultaneously, while piston 7 rotates, it is connected with counting mechanism 8 with fork 5 by rotating axle 4, as long as so writing down piston 7 number of revolutions, so that it may calculate the volume flowing through water meter, simple and convenient operation, conditioning is repaired easily.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
