Embodiment Construction
[0018] In order to better understand the above technical solutions of the present invention, a further detailed description will be given below in conjunction with the drawings and embodiments.
[0019] The first embodiment of the throttling electric three-way regulating valve of the present invention is as figure 1 and figure 2 As shown, it includes an electric actuator 10, a valve body 1, a valve core 11, an inlet A, an outlet B and an outlet C, and also includes an electromagnetic actuator 9 and a set of throttling elements. The valve body 1 is provided with a throttling chamber A0 and a diverging chamber A1 which communicate with each other. A set of throttling elements is placed in the throttling chamber A0, and the valve core 11 is placed in the diverging chamber A1. See figure 1 Partial cut-away parts. The throttling element is composed of a valve plate 5, a valve needle 2 and a valve needle spring 3. The valve plate 5 is provided with a throttle hole 6 at the positi...

The invention relates to an electric three-way throttling regulating valve suitable for a heating and cooling integrated system. A throttling element is arranged in a throttling cavity, and a valve core is arranged in a splitting cavity; an electromagnetic actuating mechanism pushes a valve needle to move in an axial direction through a mandrel, the opening degree of a throttling hole is changed,and the throttling depth is controlled; and an electric actuating mechanism is connected to the valve core through an output shaft, the valve core generates angular displacement along with the actionof the electric actuating mechanism, the distribution relationship between two splitting mouths and an outlet B and an output C is changed, and the proportion of flow distribution between the output B and the output C is controlled. The regulating range of the regulating valve is more stable than that of a thermal expansion valve and is wider, and the coolant circulating quantity in main and auxiliary loops can be reasonably distributed. A throttling and flow distribution regulating integrated structure is adopted, thus the pipeline structure of a heat pump air conditioning water heater unit is simplified, the quantity of pipeline valves is reduced, the manufacturing and maintenance cost of the product is reduced, the leakage risk of a working medium is reduced, and the heat pump air conditioning water heater unit is more friendly to the environment and saves more energy.
Description
technical field [0001] The invention relates to a control element for a combined heating and cooling system, in particular to a throttling electric three-way regulating valve suitable for a heat pump unit. Background technique [0002] With the gradual popularization of heat pump heating and hot water units, the existing throttling valves, expansion valves and control valves cannot meet the requirements of heat pump units. Chinese invention patent application "Three-way throttle valve" (Chinese patent application number 201010620279.5, publication number CN102072601) discloses a three-way throttle valve applied to heat pump hot water air conditioning units, multiple single valves connected by three-way connecting pipes Composed of one-way valve, one-way conduction reverse throttling and overpressure diverter valve. The valve fails to automatically adjust the throttling depth and solve the problem of adjusting the working fluid distribution of the heat pump system under diff...
