A pipeline flow balance device for ground source heat pump

Abstract

The invention discloses a pipe flow balance device for a ground source heat pump, which comprises a control box, the inner wall of the control box is fixedly connected with a clamping block, one side of the clamping block clamps the pipeline body, and the bottom surface of the inner wall of the control box is fixedly connected with a The support frame is fixedly connected with a hydraulic cylinder at one end away from the control box, the right side of the hydraulic cylinder is movably connected with a telescopic rod, and the middle part of the surface of the telescopic rod is movably socketed with a connecting pipe. The pipeline flow balance device used for ground source heat pumps is equipped with a hydraulic cylinder, a telescopic rod, a hinge, a connecting block, an adjusting blade, a fixed plate and a rotating shaft, and the hydraulic cylinder drives the telescopic rod to expand and contract, so that the adjusting blade and the fixed plate rotate, thereby The regulating blades are used to adjust the flow rate inside the pipe body, so as to achieve the effect of regulating the pipe flow in the buried pipe, and achieve the goal of avoiding uneven heat transfer during use, so that it is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to a pipeline flow balance device for ground source heat pumps. Background technique [0002] The ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy from shallow land energy. Usually, the ground source heat pump consumes 1kWh of energy, and the user can obtain more than 4.4kWh of heat or cooling. The concept of source heat pumps was first proposed by Swiss experts in 1912, and this technology was first proposed in the United Kingdom and the United States. The Nordic countries mainly focus on heating in winter, while the United States focuses on combined supply in winter and summer. Due to the climate conditions in the United States It is very similar to China, so the study of the application of ground source heat pumps in the United States has reference significance for th...
