Abstract

The invention relates to a flow distributor, which comprises a valve body, a sliding valve core and an adjusting component, wherein one end face of the valve body is provided with a medium inlet, the side wall of the valve body is provided with two external outlets, the side wall of the sliding valve core is provided with two internal outlets, the adjusting component is a temperature-length memory spring positioned in an inner cavity of the valve body, the sliding valve core can be attached to the inner cavity of the valve body and moved under the control of the memory spring, the two external outlets and the two internal outlets are parallelograms which have the same section shape and the same sectional area, the first external outlet can be completely coincided with the first internal outlet, and the second external outlet can be completely coincided with the second internal outlet. The flow distributor is not supplied by power, can be used singly, and can form a passive element together with other components.

Description

technical field [0001] The invention relates to a flow distributor, which can be used alone, and can also be used for a differential heat meter that relies on the power of a medium (such as water) to realize heat measurement. Background technique [0002] In today's energy-saving society, energy-saving civil heating metering has been raised to the status of national policy encouragement. Existing heat meters generally need to be driven by a power source, which has a major defect, that is, the power source of the heat meter must be replaced or checked regularly, and once the power source is exhausted or fails, the heating measurement will be suspended. Regularly replacing or checking the power supply of the heat meter will consume a lot of manpower, material resources and financial resources of the heating company. When the power supply has man-made or natural failure and the power is exhausted, the heating company will suffer losses. Contents of the invention [0003] The...
