Embodiment 1

[0046] Such as Figure 1-3 , a quantitative solenoid valve for hydraulic transmission, comprising a liquid placement part 1 , the liquid placement part 1 is in the shape of a funnel, and the lower port of the liquid placement part 1 extends downward to form a working chamber 12 . Described electromagnetic valve comprises plunger, and described plunger comprises first plunger 2, second plunger 3, first connecting post 21, and described first plunger 2 and second plunger 3 and first connecting post 21 Both ends are connected. The side opposite to the connection between the second plunger 3 and the first connecting column 21 is provided with a second connecting column 31, one end of the second connecting column 31 is connected to the second plunger 3, and the other end is connected to a spring 4, and the spring 4 The other end is connected with the bottom of the working chamber 12. The first plunger 2 and the second plunger 3 are respectively provided with a first seal ring 8 a...

Embodiment 2

[0054] Example 2

[0055] The principle of this embodiment 2 is the same as that of embodiment 1, and this embodiment 2 focuses on solving the problem of detergent residues generated in embodiment 1.

[0056] Such as Figure 4-6 , Compared with Embodiment 1, the difference is that a water inlet valve 15 is set in the water inlet branch 5, and the water inlet valve 15 can control the switch of the water flow. The water inlet valve 15 can be a solenoid valve or other applicable valves. In Embodiment 2, the water inlet branch 5 is higher than the liquid outlet pipeline 7 . During the downward movement of the plunger, if Figure 5 , when the solenoid valve is in the second state, when the first plunger 2 closes the liquid inlet, the liquid outlet pipeline 7 is located below the second plunger 3, and the water inlet branch 5 is located on the side wall of the constant volume cavity 10 formed Close the water inlet valve 15 or move the second plunger 3 to the location of the wate...

Embodiment 3

[0062] The principle of this embodiment 3 is the same as that of embodiment 2 or 1, and it is an improvement on embodiment 2, which can solve the problem of difficulty in the downward flow of the washing aid in embodiment 2.

[0063] Such as Figure 7-9 , compared with Embodiment 2, the difference is that an air guide tube 16 is set on the plunger, and the air guide tube 16 runs through the first plunger 2, the second plunger 3 and the first connecting column 21 and the second connecting column 22, A connecting port 17 is provided at the bottom of the working chamber 12, and the connecting port 17 is connected to an air pump, and air is introduced into the working chamber 12 through the air pump, and the air enters the washing aid in the liquid part 1 through the air guide tube 16, so that the washing aid A slight pressure is generated inside, and under the action of the slight pressure, the washing aid is accelerated to flow downward and be injected into the cavity.

Abstract

The invention discloses a hydraulic conveying quantitative electromagnetic valve. The hydraulic conveying quantitative electromagnetic valve comprises a liquid storage part (1), a working cavity (12)and a control device, wherein the liquid storage part (1) is positioned at the upper end of the working cavity (12); a water inlet branch (5) and a liquid outlet pipeline (7) are arranged on the sidewall of the working cavity (12); a first plunger (2), a connecting piece and a second plunger (3) are arranged in the working cavity (12) from top to bottom (2), and the first plunger (2) and the second plunger (3) slide up and down along the working cavity (12) under the action of the control device; and when the first plunger (2) slides to the bottom of the closed liquid storage part, the firstplunger (2), the second plunger (3) and the working cavity (12) form a closed constant volume cavity (10) with fixed size. According to the hydraulic conveying quantitative electromagnetic valve, thequantitative conveying of a washing auxiliary agent is realized; and the valve is simple in structure, convenient to operate, smooth in conveying and small in occupied space.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a solenoid valve applied to a washing machine for controlling the circulation of washing aids. Background technique [0002] At present, most of the solenoid valves used as actuators in automation control are fully open and fully closed, which can only be used for qualitative control, and cannot be used for quantitative or various curve output control. However, in actual production practice, it is necessary to quantitatively control the flow of gas, water, oil, etc. in many occasions, so as to grasp the quantity. [0003] Patent CN92232180.9 proposes a solenoid valve that can qualitatively and quantitatively control the flow rate by electrical signals, and the valve is composed of a ball valve, a stepping motor and a scale. Using the circular linear rotary switch function of the ball valve, organically combining with the stepper motor's characteristics of controlling its circular power with e...
