Low-resistance flow-equalizing water pipe tee joint

Abstract

The invention relates to a low-resistance flow-equalizing water pipe tee joint. A main body is composed of a main pipe and thin branch pipes arranged on the main pipe, each thin branch pipe is composed of an inner pipe and an outer pipe which are the same in inner diameter, the main body is in an L-shaped natural bending shape, the inner pipes are fixedly arranged on the inner pipe wall of the main pipe, the outer pipes are arranged on the outer surface of the main pipe in an extending manner, during water supply, the inner pipes achieve the flow dividing pipe effect, water in the main pipe can enter the inner pipes according to the designed water amount, the flow direction is smoothly changed, then, water can flow out of the outer pipes, during water returning, the thin branch pipes achieve the backflow pipe effect, backflow water flows to the main pipe through the inner pipes along the walls of the thin branch pipes, the water flow direction is consistent with the flow direction in the main pipe, and non-resistance natural mixing is achieved. Due to removing of an adjusting valve, the process of converting static pressure into dynamic pressure does not exist, the work manner thatin the prior art, the static pressure is converted into the dynamic pressure is effectively overcome, the shortcomings that due to arrangement of the adjusting valve, the water flow resistance is large, the water speed uniformity is poor, energy consumption is large, the flow is difficult to control, the products difficultly meet the design requirements, and meet the market application are overcome effectively, and the very high practicability and the worshipful market application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of water supply fittings, in particular to a low-resistance equal flow pipe tee suitable for all water supply and return systems such as air-conditioning chilled water and cooling water systems, heating and hot water circulation systems, and large-scale regional cooling and hot water supply circulation systems. . Background technique [0002] figure 1 It is a schematic diagram of the commonly used water pipe tee structure at present. The main body is composed of the main pipe 1 and the thinner branch pipe 2 arranged on the main pipe 1. The pipe end chambers on both sides of the main pipe 1 and the pipe end chambers of the thinner branch pipe 2 are respectively provided with convenient Regulating valve A 3, regulating valve C 4 and regulating valve B 5 that control water flow are adjusted. When performing water supply operations, the hydrostatic pressure in the main pipe 1 is high, and the hydrostatic press...

Problems solved by technology

When performing water supply operations, the hydrostatic pressure in the main pipe 1 is high, and the hydrostatic pressure in the thinner branch pipe 2 is smaller. It flows out through the thinner branch pipe 2; when the water return operation is performed, the hydrostatic pressure in the main pipe 1 is small, and the static pressure in the thinner branch pipe 2 is large, and the water flows from the thinner branch pipe 2 to the main pipe 1; due to the static pressure, the water is vertical When the water flow enters the main pipe, it will be impacted by the original water flow in the main pipe parallel to the axis of the main pipe, which will inevitably create resistance to the water flow and cause a large amount of energy loss.

In addition, there is also energy loss when the hydrostatic pressure changes to the hydrodynamic pressure

Therefore, the resistance of the water pipe tee is very large, making it difficult for the water distribution of the thinner branch pipe and the main pipe to meet the design requirements

For this reason, there have been figure 1 The method of adding a regulating valve is shown to adjust and control the flow of water, but after adding a regulating valve, it is very difficult to adjust the water flow as required, and the regulating valve itself will also bring resistance to the water flow during the working process, so the loss is even greater. Large, so that the pump energy consumption increases

Therefore, the commonly used water pipe tees generally have many shortcomings such as complex structure and unscientific and reasonable structure, poor convenience and work stability, high product cost, and it is difficult to meet product design requirements and meet actual use requirements. Unsatisfactory in terms of sex and practicality
