Embodiment Construction

[0020] Embodiments of the present invention are described in more detail below with reference to the accompanying drawings.

[0021] Such as figure 1 Shown is a solenoid valve for noise-reducing wastewater. The valve body 1 is provided with a water inlet 21 for water flowing into the solenoid valve and a water outlet 31 for water flowing out of the solenoid valve. Wherein, the water inlet 21 flows into the water inlet chamber 2 , and the water outlet 31 communicates with the water outlet chamber 3 . image 3 It is a structural schematic diagram of the valve body 1 in this embodiment, the water outlet chamber 3 is a circular chamber arranged in the middle of the valve body 1, the water inlet chamber 2 is an annular chamber surrounding the outside of the water outlet chamber 3, combined with figure 1 , The water inlet chamber 2 and the water outlet chamber 3 are open chambers in the valve body 1, and the two chambers are sealed to each other by the sealing assembly 7.

Abstract

The invention discloses a noise reduction waste water electromagnetic valve which comprises a valve body provided with a water inlet and a water outlet, a sealing component and a buffer cavity; the valve body is internally provided with a water inlet cavity and a water outlet cavity; when the electromagnetic valve is closed, the sealing component mutually separates the water inlet cavity and the water outlet cavity; the water inlet is communicated with the water inlet cavity, the water outlet is communicated with the water outlet cavity, and the water inlet cavity and the water outlet cavity are mutually separated through the sealing component; the buffer cavity is communicated with the water outlet cavity; the wall of the buffer cavity is provided with a pinhole; and the water inlet cavity is connected with the buffer cavity through the pinhole. The noise reduction waste water electromagnetic valve can effectively lower noises produced when a large-flow and high-water pressure water flow flows through the waste water valve when the waste water electromagnetic valve works under the conditions of high water pressure and large flow.

Description

technical field [0001] The invention relates to the field of electromagnetic valve noise reduction, in particular to a noise reduction electromagnetic valve for wastewater. Background technique [0002] In the water purification equipment, the wastewater solenoid valve is used to discharge the wastewater, so that the concentration of water at the front of the RO membrane will not be too high, so as to achieve the effect of protecting the RO membrane in the water purifier and ensure the service life of the RO membrane. The structure of the waste water solenoid valve is roughly the same as that of the water inlet solenoid valve, the difference is that there is a small hole connecting the water inlet and the water outlet on the valve body. When the solenoid valve is not energized and the valve is not opened, a certain small flow of waste water can flow out through the solenoid valve to achieve the purpose of discharging waste water; when the waste water solenoid valve is energi...
