(2) background technology
Household measurement heat-supplying charges needs to adopt calorimeter to measure, the mechanical type calorimeter of prior art is supplied water by the impeller type flowmeter of measuring hot water flow and measurement and two thermometers of return water temperature are formed, and wherein impeller type flowmeter is similar to the mechanical type water meter, it is made up of base table seat, base table lid and watch core.When current when the impeller type flowmeter, drive the impeller rotation in the watch core, the rotation number of impeller has just characterized the water yield of being passed through, and sends by the sensing chip on the impeller and the signal transmitter on the impeller cover revolution with impeller.
The impeller type flowmeter manufacture method of prior art is: the base table seat is made by monoblock cast or whole punching press by the copper metal material, the base table lid is like this too, respectively go out to dock rib-loop on the top of base table seat and the bottom of base table lid then with the lathe car, and the surface, inside and outside of base table seat and base table lid polished processing, at last at base table seat mounted inside watch core.
Impeller type flowmeter of the prior art exists the defective that physical dimension is big, processing technology is complicated, processing capacity is big, and spindle nose easily weares and teares during owing to the impeller shaft rotation, cause the biased swing that moves with impeller of axle, make that space length changes between sensing chip on the impeller and the inductive head on the impeller cover, picking up signal to the flowmeter signal transmitter brings very big difficulty, make the sensitivity of watch core descend the poor durability of flowmeter.
(3) summary of the invention
The physical dimension that prior art exists is big, cost is high in order to overcome, and the deficiency of the permanance of flowmeter and degree of accuracy difference, and the present invention proposes a kind of impeller type flowmeter.
The present invention includes watch core base table seat, base table lid, back shaft, impeller blade, sensing chip and inductive head, wherein: the water pipe at base table seat and flowmeter two ends adopts the Shooting Technique global formation, the base table lid also adopts the Shooting Technique global formation, cover on joint portion, the diametric both sides of the water pipe tube wall at base table seat and base table, pilot hole is arranged respectively, this pilot hole covers mutually two semi-circular hole of knot portion and merges and form by being distributed in base table seat and base table, and its diameter is identical with the watch core back shaft; Impeller blade adopts the Shooting Technique global formation, and axis hole is arranged in impeller.Base table seat and base table lid are fixed together, and the watch core back shaft is fixedly mounted in the pilot hole that is synthesized by two semi-circular hole; With impeller blade by Bearing Installation on the watch core back shaft, and the sensing chip of sender is installed on the blade, inductive head is installed in and the corresponding base table exterior surface in the position of sensing chip.
Base table lid, base table seat and watch core adopt the moulding of engineering plastics integral molded plastic among the present invention, and volume is little, in light weight, and the stability of impeller type flowmeter and precision are improved, and reduce processing capacity, reduce and have made cost.
