Integrated water returning device for consumer heat inlet

Abstract

The invention relates to an integrated water returning device for a consumer heat inlet. The integrated water returning device for the consumer heat inlet is applied to water returning of the consumer heat inlet of a building. The integrated water returning device for the consumer heat inlet is characterized in that an inlet and an outlet of a five-way adjusting valve correspondingly communicate with a front end welding ball valve and a rear end welding ball valve through pipelines; pressure gauge assemblies are correspondingly arranged among the five-way adjusting valve, the front end welding ball valve and the rear end welding ball valve; pressure gauges and valves are arranged on the pressure gauge assemblies; a tee joint is mounted on the rear end pressure gauge assembly. The integrated water returning device for the consumer heat inlet integrates six major functions, namely, the closing function, the filtering function, the sewage draining function, the adjusting, the observing function and the heat preserving function, so that flanges and bolts can be saved; a pipeline is easy to realize heat preserving, and lots of heat loads can be decreased, and as a result, lots of heat losses of a heat supply system can be decreased, and the heat supplying, the energy conservation and the emission reduction can be achieved. The integrated water returning device for the consumer heat inlet is simple in structure, convenient to mount and repair, easy to preserve heat, and easy to drain sewage; the integrated water returning device for the consumer heat inlet is a brand new water returning device for the consumer heat inlet.

Description

technical field [0001] The invention belongs to the field of heat supply, and in particular relates to a return water device for integrated thermal inlets of buildings. Background technique [0002] The thermal inlet facility of the building is the system where the heating system connects the external grid and the building. The thermal inlet facilities are divided into return water and return water devices. The thermal inlet facilities have the functions of shutdown, filtration, sewage discharge, adjustment, observation, etc., and are installed in the building entrance valve well or stairwell. [0003] The return water device of the original thermal inlet facility is connected by flanges because the shut-off valve, filter and control valve are used, which makes the entire thermal inlet device particularly bulky and heavy, which is not easy to install and maintain. Due to the flange connection, the uneven pipeline is not easy to keep warm, and the exposed valve wastes a lot ...

AI Technical Summary

Problems solved by technology

[0003] The return water device of the original thermal inlet facility is connected by flanges for shut-off valves, filters, and control valves, which makes the entire thermal inlet device particularly bulky and cumbersome, which is not easy to install and maintain

Due to the flange connection method, the uneven pipeline is not easy to keep warm, and the exposed valve wastes a lot of heat load, and the flange connection also wastes a lot of bolts, gaskets and other materials

[0004] The return water device of the original thermal inlet is also equipped with a bypass pipeline and a bypass valve, and a filter (usually a Y-type filter) is added. This filter cannot realize online sewage discharge and backwashing functions, which increases maintenance costs.
