Electromagnetic valve provided with wastewater throttling device and having anti-blocking and silencing functions

Abstract

The invention relates to electromagnetic valves with wastewater throttling devices in the water treatment field, in particular to an electromagnetic valve provided with a wastewater throttling device and having anti-blocking and silencing functions. According to the technical scheme, the electromagnetic valve provided with the wastewater throttling device and having the anti-blocking and silencing functions is characterized in that one side of a valve body is provided with a containing cavity, a wastewater rod is inserted in the containing cavity, and a buffer cavity is formed between the middle of the wastewater rod and the inner wall of the containing cavity; and the valve body is provided with anti-blocking pin holes penetrating through a water inlet channel and the buffer cavity, the wastewater rod is provided with a wastewater hole penetrating through the buffer cavity and a water outlet channel, the aperture of the anti-blocking pin holes is small than that of the wastewater hole, and water in the water inlet channel can pass through the anti-blocking pin holes, the buffer cavity and the wastewater hole and then flows out from the water outlet channel. By the adoption of the technical scheme, the problems existing in the prior art are solved, and the novel electromagnetic valve provided with the wastewater throttling device can well prevent the wastewater hole from being blocked and effectively reduce noise.

Description

technical field [0001] The invention relates to a wastewater ratio solenoid valve in the field of water treatment, in particular to a wastewater ratio solenoid valve with anti-blocking and noise reduction functions. Background technique [0002] Wastewater ratio solenoid valves play an extremely important role in water treatment equipment such as reverse osmosis water purifiers and direct drinking machines. Install a wastewater ratio solenoid valve at the concentrated water discharge port. When the wastewater ratio solenoid valve is not powered, the pretreated tap water will be further treated through the reverse osmosis membrane, and the produced water will flow out from the outlet of the reverse osmosis filter element, and the concentrated water produced The waste water flows out through the solenoid valve. [0003] When the wastewater ratio solenoid valve is energized, the pretreated tap water enters the reverse osmosis filter element. Since the valve port of the wastewa...
