Abstract

The invention discloses a special dual-U-shaped dual-temperature conversion control combined valve body, and relates to the technical field of ground source heat pumps. The special dual-U-shaped dual-temperature conversion control combined valve body comprises a shell, a valve cavity is formed in the shell, a first pipe section, a second pipe section, a third pipe section, a fourth pipe section, a fifth pipe section and a sixth pipe section are separately arranged on the outer side of the shell, a screw rod is rotationally installed in the valve cavity, and a sliding block is connected to the screw rod in a screwed mode. An adjusting seat is arranged on the lower wall of the sliding block,a first communicating cavity and a second communicating cavity are arranged on the lower wall of the adjusting seat, and a motor used for driving the screw rod to rotate is arranged on the outer wall of the shell. The special dual-U-shaped dual-temperature conversion control combined valve body is compact in structure, the motor drives the end sliding block to move and synchronously drives the adjusting seat to slide, a first station and a second station are rapidly switched, so that the communication relation between all pipelines is changed, switching between the refrigerating working condition and the heating working condition is achieved, reversing is convenient, the sliding stability of the sliding block is improved through the arrangement of an auxiliary assembly, and convenience is brought to use of people.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to a dual-U-shaped dual-temperature conversion control combined valve body. Background technique [0002] The ground source heat pump air conditioner adopts an energy-saving and environmentally friendly ground source heat pump system. Its cold and heat source adopts a flexible installation and easy-to-control buried pipe type soil source heat pump system, also known as a soil coupled heat pump system. Specifically, the vertical buried pipe method is adopted, and water is used as the cold and heat carrier. The water circulates between the heat exchange pipe buried in the soil and the heat pump unit to realize the heat exchange between the unit and the soil. The existing ground source The reversing of the heating and cooling working conditions of the heat pump air conditioner usually uses a series four-way reversing valve to realize the reversing work. Although this m...
