Abstract

An improved heat meter is equipped with two changeable impellers, the blades of which the have the same shape, size and quantity. The blades are made of bimetallic strip material with special shape. The flows of liquids in two cavities with impellers are the same. Another cavity in a meter casing is equipped with transmission components and a counting device. The transmission components include a differential gear transmission system, which is equipped with two input terminals and an output terminal. The two impellers are connected in a way of fixing with the two input terminals of the differential gear transmission system. The output terminal of the differential gear transmission system is connected with the counting device and drives the counting device to operate. The invention has the advantages of compact structure, reduced whole volume, lowered manufacturing cost and easy unified encapsulation.

Description

technical field [0001] The present invention relates to an improved heat meter. Background technique [0002] At present, the heating metering is gradually transitioning to households. In order to reduce the transformation cost of the heating system, the existing technology makes the volume of the heat meter larger, the structure is not compact, and the manufacturing cost is high; it is not conducive to the overall sealing. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide an improved heat meter. [0004] The technical solution of the present invention is: an improved heat meter, which is characterized in that: the vanes of the two variable impellers have the same shape, size, and number, and the vanes are made of bimetallic sheet material into a specific shape, and the two impellers are equipped with The flow rate of the fluid in the two chambers is the same, and there is another chamber in the w...
