Description

Vertical buried pipe for ground source heat pump

technical field

The utility model relates to a buried pipe used in a ground source heat pump system, in particular to a vertical buried pipe for the ground source heat pump.

Background technique

The vertical buried pipe of ground source heat pump is a key part in the design of water ground source heat pump system. Due to the particularity and importance of vertically buried pipes of water ground source heat pumps, it is not convenient for later inspection and maintenance to bury pipes underground. Special attention should be paid during the construction process, and damage to the buried pipe should be avoided as much as possible to reduce the failure rate of the later system operation. At the same time, the buried pipe will also be damaged due to the mistakes of the construction personnel during the construction process.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a vertical buried pipe for ground source heat pumps. The failure rate can be reduced as much as possible through the improvement of the buried pipe.

The utility model is realized through the following technical solutions. The utility model includes a vertical buried pipe, and also includes a pressure gauge and an air intake valve, and the pressure gauge and the air intake valve are respectively arranged at both ends of the vertical buried pipe.

The vertical buried pipe is a U-shaped pipe, the pressure gauge is movably connected to one end of the U-shaped pipe, and the air intake valve is movably connected to the other end of the U-shaped pipe. The pressure gauge and the air intake valve can be easily disassembled. After successful burial, the pressure gauge and intake valve can be removed.

The pressure gauge and the air inlet valve are respectively sealed and connected to the two ends of the U-shaped pipe, which can realize the detection of the airtightness of the vertical buried pipe.

Compared with the prior art, the utility model has the following advantages: the utility model installs pressure gauges and air intake valves at both ends of the vertical buried pipe respectively, and performs certain pressure on the vertical buried pipe before lowering the pipe. The appearance damage of the buried pipe is detected before the pipe, and the change of the pressure gauge can be observed in real time during the pipe lowering process, so that it can be remedied in time, which not only improves the success rate of the ground source well, but also effectively reduces various construction accidents caused by human factors .

Detailed ways

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

As shown in FIG. 1 , this embodiment includes a vertical buried pipe 1 , a pressure gauge 2 and an air intake valve 3 , and the pressure gauge 2 and air intake valve 3 are respectively arranged at both ends of the vertical buried pipe 1 . There are two vertical buried pipes 1 in this embodiment, and pressure gauges 2 and intake valves 3 are arranged at both ends of each vertical buried pipe 1 .

The vertical buried pipe 1 of this embodiment is a U-shaped pipe, the pressure gauge 2 is movably connected to one end of the U-shaped pipe, and the intake valve 3 is movably connected to the other end of the U-shaped pipe. The pressure gauge 2 and the air intake valve 3 are respectively sealed and connected with the two ends of the U-shaped pipe, which can realize the detection of the airtightness of the vertical buried pipe 1 .

Press each vertical buried pipe 1 to 0.8MPa before lowering the pipe. Not only can the appearance of the pipe be inspected for cracks, blisters and damage before the lowering of the pipe, but also the change of the pressure gauge 2 can be observed at all times during the lowering of the pipe. , to take timely and effective remedial measures. It greatly improves the efficiency of running the pipe, and at the same time, it can avoid construction errors caused by the carelessness of construction personnel during the construction process, reduce certain construction costs, and try to avoid other economic and construction period losses caused by abandoned wells. At the same time, after the vertical buried pipe 1 is successfully installed, both the pressure gauge 2 and the intake valve 3 can be disassembled to realize reuse.
