Abstract

The utility model discloses an insertion-type ultrasonic water meter. The insertion-type ultrasonic water meter comprises a detachable large-caliber mechanical water meter shell, ultrasonic transducer modules used for detecting flow are inserted into an opening of the shell, and the ultrasonic transducer modules, the opening of the shell and an inner cavity of the shell work in cooperation with each other to seal the opening at the same time. Compared with the prior art, a large-caliber mechanical water meter can be easily and effectively developed to be the insertion-type ultrasonic water meter, the instantaneous flow rate and accumulated flow rate of water can be simultaneously metered and digitally displayed, and readings can be visually acquired. Transducers are good in installing and sealing performance and long in service life, and the developed ultrasonic water meter is small in pressure loss; because a sensing machine core can be manufactured into a module and the module is simple in structure and convenient to install, people can directly develop and update mechanical water meters with poorer metering performance and the need for being replaced on a pipe network just by replacing a machine core device.

Description

A kind of plug-in type Ultrasonic water meter
Technical field
The utility model belongs to water meter technical field, especially relates to a kind of plug-in type Ultrasonic water meter.
Background technology
At present, mostly heavy caliber mechanical water meter is to adopt spiral type structure, mainly contains vertical Woltmann water meter and horizontal screw wing type water meter.The feature of vertical Woltmann water meter is that current flow into along the direction of impeller shaft, and in pipeline, the flow velocity of aqueous fluid is added on impeller completely, and the blade of impeller is evenly rotated under current drive.Its impeller shaft direction is perpendicular to the axis direction of water supply line, and therefore watermeter shell structurally requires to allow water (flow) direction that 90 ° of deflections occur.Because impeller is vertical placement, rotatablely moving of impeller can directly drive integrating mechanism counting like this, and the loss in energy transfer process of this water meter is smaller, it is higher to measure sensitivity, can be used for measuring feel in less flow value.In horizontal screw wing type water meter, the direction of impeller shaft and conduit axis direction overlap, and the shell of water meter forms a part for craspedodrome pipeline.Rotatablely moving of impeller is delivered on a vertical axis by worm screw by the turbine on its axle, and then drives integrating mechanism work, and this kind of water meter negotiability is strong, and the pressure loss is little, the larger and metastable occasion use of flow of the water consumption of being everlasting.
On the other hand, mechanical water meter also has and is much difficult to the shortcoming avoided, such as: (1) is because its driving-chain (axle system) Gap-Ratios is large and axle is that the reasons such as very easily wearing and tearing cause its measuring repeatability well not keep, the in the situation that of particularly containing particle, impurity in water, axle system wearing and tearing sooner, more serious, greatly shorten serviceable life, and measuring error can increase; (2) design of mechanical water meter, assembled after, its graph of errors nonlinear characteristic is serious, and shape is non-adjustable, in most cases also can only translation adjustment; (3) low discharge and initial-flow characteristic are subject to the impact of temperature, and water temperature declines, Small flowrate measurement characteristic variation, and it is large that sensitivity threshold becomes, and part material temperature characteristic is undesirable, and its shape changes with temperature change; (4) mechanical water meter is because its part of paddling is existed by moving component, and build-up of pressure loss is larger; (5) if its long-term mistake under current-carrying capacity is worked, drive disk assembly is very easily tired, causes deformation set or damage, affects water meter indication error and measurement accuracy.(6) and, domestic and international existing heavy caliber mechanical water meter can only be measured the integrated flux of discharge, can not be used for the measurement of instantaneous delivery.Therefore, mechanical water meter is using after certain hour, its metering performance variation gradually, and shorten serviceable life, so that must regularly replace it.Heavy caliber helical vane type water meter is from whether removable angle can be divided into again Dismantlable helical blade type water meter and non-dismountable helical vane type water meter.For Dismantlable helical blade type water meter, we can take the mode of changing movement by its metal shell secondary utilization, but this measure need to be recalibrated complete machine, unavoidably remove from pipe network, labour intensity is large, and if whole table is changed, not only labour intensity is large, also can cause the very large wasting of resources, produce and run counter to low-carbon (LC) that we pursue life, low-carbon (LC).
