Abstract

The utility model provides a U-shaped elbow of a ground source heat pump which comprises an upper support, a lower support and a base, wherein a pipe connector connected with a pipeline is arranged on the upper support; the upper support and the lower support are welded into an inner U-shaped channel; and the interior of the U-shaped channel is designed as a cambered surface. The U-shaped elbow of the utility model is convenient to construct, time-saving, excellent in self-cleaning and reliable in connection, and has low probability of being blocked by miscellaneous objects in the water.

Description

A kind of return bend of earth source heat pump

Technical field

The utility model belongs to earth source heat pump structure field, particularly relates to a kind of return bend of earth source heat pump.

Background technology

Geothermal heat pump air-conditioner is to utilize a large amount of low temperature heat energies source of storing in underground, rock, underground water or other the medium to provide heating installation, air-conditioning and hot water for space.The waste thermal energy that air-conditioning is got rid of during summer is transported to underground, and the heat energy during winter in the soil is extracted, and gives air conditioning and heating.Earth source heat pump is the most comfortable, efficient, environmental protection, energy-conservation technology up to now, is up-to-date, the most high-grade in the world air-conditioning and heating system at present, has obtained using widely.

At present the used return bend of geothermal heat pump air-conditioner in work progress owing to go into the well darker, water in the well is bigger to the buoyancy of tubing, return bend is lighter, one stay bolt need be set in the return bend middle part, the workmen utilizes metallic rod, by stay bolt tubing is pressed onto the predetermined degree of depth, utilizes the metallic rod fragile pipeline construction difficulty of constructing big.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of return bend simple in structure is provided.

To achieve these goals, the technical scheme of employing is as follows:

A kind of return bend of earth source heat pump comprises upper bracket, undersetting and base, and described upper bracket is provided with the Pipe jointer that is connected with pipeline, and upper bracket and undersetting welding back form inner U-shaped passage, design for cambered surface in the described U-shaped passage.

Described undersetting inner hollow, and be placed with pouring weight, undersetting and base pass through welded seal.

Described Pipe jointer is an injection molded, and it is arranged on upper bracket, and with the U-shaped channel connection.

The utility model can use the underground return bend of environmental protection PE material preparation geothermal space conditioning, and return bend is welded to form by upper bracket, undersetting, base assembling.Upper bracket is provided with the passage that is connected with pipeline, and last undersetting is welded to form inner U-shaped passage, and the cambered surface design is all adopted in the connection of inner U-shaped passage, and the flow resistance that has reduced water also has automatically cleaning simultaneously, is difficult for foreign material in the residual water; Bonding area leaves enough spaces, and welding can not stopped up firm welding; In indoor design weight is arranged in addition, construction can be time saving and energy saving, make the utility model easy construction, save time, have be difficult for by the foreign material in the water stop up, the automatically cleaning ability is good, connects reliable.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Structure of the present utility model as shown in Figure 1, the return bend for earth source heat pump comprises: return bend upper bracket 1, return bend undersetting 2, base 3, weight 4.Return bend upper bracket 1 is provided with the Pipe jointer that passes through an injection molded 5 that is connected with pipeline; Return bend upper bracket 1 and the inner U-shaped passage 7 that forms in return bend undersetting 2 welding backs; The U-shaped passage 7 inner cambered surfaces 6 that form with the minimizing resistance to water-flow, and in use are difficult for impurity in the residual water; Be placed with weight 4 in return bend undersetting 2, return bend undersetting 2 can be by air or aqueous corrosion by weight 4 with base 3 welded seals; Return bend of the present utility model has reduced the buoyancy of WIH to the U-shaped connector because inner weight 4 produces the power of deadweight when construction, save the engineering time.
