Abstract

The invention discloses a heat-induction partial pressure type energy-saving regulating valve for a heat pump unit, comprising a valve body, a valve stem is rotatably installed on the inner wall of the valve body, a flow blocking sheet is installed on the valve stem, and a side of the valve body is rotatably mounted. A pressure-sensing cavity and a pressure-regulating cavity are respectively opened in the wall, and the pressure-sensing cavity and the pressure-regulating cavity are symmetrically arranged. A pressure limiting plate is installed in the cavity, one end of the valve rod close to the pressure regulating cavity extends into the pressure regulating cavity and a right-angle pressure regulating rod is installed. In the present invention, the temperature sensing package is arranged in the valve body to reduce interference and increase the accuracy while increasing the response speed. The resistance value between the connecting posts is adjusted by sliding the right-angle pressure regulating rod and the elastic clip on the arc-shaped resistance ring, so as to realize the wiring installation. The function of adjusting the voltage reduces the energy consumption of the heat pump unit.

Description

technical field [0001] The invention relates to the field of heat pump equipment, in particular to a thermal induction partial pressure energy-saving regulating valve of a heat pump unit. Background technique [0002] A heat pump unit is usually composed of an evaporator, a condenser, a liquid storage tank, a compressor, and an expansion valve. The expansion valve plays a role in regulating the flow of refrigerant in the heat pump unit to prevent insufficient utilization of the evaporator area and knocking. [0003] Existing expansion regulating valves usually use a temperature sensing package and a capillary tube to sense temperature and transmit the temperature sensing value. The capillary tube is separated from the valve body so that the capillary tube is easily affected by the external temperature, resulting in low adjustment accuracy, and after expansion adjustment, it can only make the refrigerant The flow rate varies and the fan speed on the evaporator side requires a...
