Intelligent temperature control water-mixing center

Abstract

The invention provides an intelligent temperature control water-mixing center which is installed at the position of the front end of a water distributor and a water collector or the water supply or water return position of a wall-hanging stove, hot water generated by the wall-hanging stove flows into a water inlet hole at the bottom of a water-mixing valve core from a water supply port through a heat supply pipeline, enters a shielded circulating pump through a first circulating pump port, flows to a water supply three-way connecting assembly through a second circulating pump port, enters a water distributor main pipe through a mixed water supply port to reach a water collector main pipe through a floor heating pipe, flows into a primary water return port, finally flows out through the primary water return port and returns to the wall-hanging stove through a return water pipeline, and a circulation loop is formed. A single water-mixing valve can replace a matching product composed of a plurality of unifunctional valve parts, is safe and reliable and reduces manufacturing cost. PLC programming is set in a temperature control panel to control the temperature of the mixed water according to time periods, the energy consumption is reduced to the largest extent, and energy is saved; the temperature control panel can control and command an electric heating executor and the circulating pumps to operate; an adjusting hand wheel can be arranged, and manual operation can be performed under special conditions such as outage.

Description

technical field [0001] The invention relates to the field of heating systems, and more specifically, to an intelligent temperature-controlled water mixing center. Background technique [0002] my country's "JGJ 142-2012 Radiant Heating Technical Regulations" has the following regulations on the water temperature of low-temperature floor radiant heating (abbreviation: floor heating): the water supply temperature should not exceed 60°C, and the temperature difference between supply and return water should not exceed 10°C and should not be less than 5°C. The water supply temperature should be 35~45℃. Excessive temperature has a great impact on the service life and aging performance of the floor heating pipe, so controlling the water temperature is of great significance for the long-term safe work of the floor heating. At present, in offices, civil buildings and residential quarters, many systems that use floor heating and radiator heating coexist, which will lead to inconsisten...

Problems solved by technology

Its disadvantages: the structure of the thermostatic mixing water valve is relatively complicated, the manufacturing requires high precision and the flow rate is too small, and the temperature of the mixed water can only be adjusted manually, which cannot guarantee the heating of a large area and is inconvenient to use

Its disadvantages: the three-way ball valve adjusts the opening cycle slowly, which makes the water mixing effect slow. In addition, there are hidden dangers of water leakage in the combination of too many parts. Too many parts increase its water flow resistance, and the water pressure causes
