Embodiment Construction
[0017] The present invention will be further described through the embodiments below with reference to the accompanying drawings.
[0018] Refer to attached Figure 1~6 , a water inlet solenoid valve, the water inlet solenoid valve includes a valve body 1, a valve one 2, a valve two 3 and a valve three 19 are arranged on the valve body 1, wherein the water outlet one 4 on the valve one 2 is a round table shape, below the water outlet one 4 is provided with a floating ball chamber 4b, between the water outlet one 4 and the floating ball chamber 4b is provided with a water sealing ring 2 4c, the floating ball chamber 4b is provided with a movable floating ball 4d, and the floating The lower end of the ball chamber 4b is provided with an end cover 4a. When the water flow reverses, the floating ball 4d rises under the action of the water flow to resist the water sealing ring 2 4c, closing the water outlet 1 4; the water outlet 2 5 on the valve 2 3 is in the shape of a cylinder Sh...

The invention discloses a water supply solenoid valve which enables residual water in a water in a water supply valve to be drained conveniently. The water supply solenoid valve aims to overcome the defect that due to the fact that residual water exists in a water pipeline after an existing water supply solenoid valve is closed, and use is inconvenient. The water supply solenoid valve can drain residual water in an outlet pipeline rapidly after being closed. The water supply solenoid valve comprises a valve body. At least two valve gates are arranged on the valve body, wherein a first water outlet in the first valve gate is in a circular truncated cone shape, a floating ball chamber is formed below the first water outlet, a second water sealing ring is arranged between the first water outlet and the floating ball chamber, a movable floating ball is arranged in the floating ball chamber, and an end cover is arranged at the lower end of the floating ball chamber. When water flows reversely, the floating ball ascends and abuts against the second water sealing ring under the action of water flow and closes the first water outlet. A guide pipe is arranged between the first valve gate and the second valve gate, one end of the guide pipe is communicated with the first valve gate, and the other end of the guide pipe is communicated with the second valve gate. Compared with the existing water supply solenoid valve, the water supply solenoid valve has the advantages that no residual water exists and the water supply solenoid valve is convenient and fast to use.
Description
technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a water inlet solenoid valve which is convenient for discharging residual water in a water inlet valve. Background technique [0002] In the existing water inlet solenoid valve used in drum washing machines, each water outlet of the solenoid valve is independent, and one side is communicated with the atmosphere. After the solenoid valve is closed, some water will remain in the hose due to the negative pressure at the water outlet. When the user opens the door cover after washing the clothes, the residual water in the hose will flow out. This phenomenon affects the washing and drying of the washing machine. Effect, when serious dripping to the outside of the washing machine, it will cause adverse impact on the environment and bring inconvenience to the washing machine user. Contents of the invention [0003] The purpose of the present invention is to provide a water inl...
