Embodiment Construction

[0038] The main structure of the multi-output control valve of the present invention is shown in Figures 1a and 1b, which can be divided into three parts from the external structure, including: a valve body part 1, a motor stator part 2, and a mounting frame 3. A stator part 2 is provided at one end close to the rotor magnetic steel 1.1.5, the valve body part 1 is placed in the shaft hole 2.12 of the stator part 2 as shown in Figure 8, and the installation frame 3 is fixed on the valve body part 1 and The stator parts 2 are sleeved on the valve sleeve 1.11 of the valve body part 1 .

[0039] The above-mentioned valve body part 1 comprises: rotor part 1.1, spool seat 1.2, spool 1.3a, 1.3b, 1.3c, spring 1.4a, 1.4b, 1.4c, gasket 1.5a, 1.5b, 1.5c, cam 1.6, valve nozzle 1.7a, 1.7b, 1.7c, positioning column 1.9, valve seat 1.10, valve sleeve 1.11, outflow pipe (also called outlet pipe) 1.12a, 1.12b, 1.12c, inflow pipe (also called inlet pipe) Tube) 1.13, circlip 1.14.

Abstract

The invention discloses a multiple-output controlled valve, which is characterized by the following: closing valve mouth with spring force on back of gasket; opening gap between arcuate boss on spool and lower dent of cam at the state of closing valve mouth; choosing rubber material or other plastic rubber or like soften material gasket as element to close the valve mouth; decreasing fineness and concentricity of the valve mouth greatly. This invention possesses small motor power consumption and low preparing cost.

Description

technical field [0001] The invention relates to a multi-output control valve using a stepping motor as a driving source, which performs multi-output on-off control for inflowing liquid or gas, and is especially suitable for refrigeration systems, especially refrigerator refrigeration systems, for refrigerant distribution regulation and control. Background technique [0002] As a device for opening and closing the refrigerant flow path of refrigerators, air conditioners or other refrigeration appliances to control the temperature of the refrigeration chamber connected to the flow path, a solenoid valve or a stepping motor control valve is generally used for switching. control. However, the system controlled by ordinary solenoid valves has the disadvantages of loud sound and large volume when the solenoid valves are opened and closed, and when several refrigerant flow paths need to be controlled, several solenoid valves are required for control. [0003] For example, the Chin...
