A self-cleaning wastewater solenoid valve

Abstract

The invention relates to a self-cleaning waste water electromagnetic valve, and specifically relates to a self-cleaning waste water electromagnetic valve used in a reverse osmosis purification system. The technical scheme of the self-cleaning waste water electromagnetic valve is as follows: the self-cleaning waste water electromagnetic valve is characterized in that a mounting through hole is arranged below a valve seat inside a valve body, a self-cleaning throttle mechanism is arranged inside the mounting through hole, the self-cleaning throttle mechanism comprises a throttle valve core, a spring and a throttle adjusting pin, one end of a throttle hole being communicated with a water inlet passage is a water inlet end, the other end being communicated with a water outlet through hole is a water outlet end, one end of the throttle adjusting pin is fixedly arranged on the valve body, the other end is opposite to the water outlet end of the throttle hole; the throttle valve core is able to achieve an axial movement inside the mounting through hole under the effect of water pressure and the spring, so as to form an insertion fit of the throttle adjusting pin and the throttle hole. By employing such a scheme, the self-cleaning waste water electromagnetic valve which is able to automatically cleaning the throttle hole via the changes of water pressure is provided.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a self-cleaning waste water solenoid valve used in a reverse osmosis purification system. Background technique [0002] There is no such valve in the prior art. The ordinary solenoid valve only has the function of closing and opening, so the structure is very different. Some of its principles are close to the traditional one-way throttle valve. The one-way throttle valve mainly It consists of a valve body and a valve core assembly, the valve body contains a throttle hole, the valve core assembly is inserted into the throttle hole, and the flow path pressure of the valve body is adjusted through the depth of the insertion, while the throttle flow Because the channel is relatively small, it is used for a long time. Objects such as calcium and magnesium ions in the water will crystallize in the throttle channel and block the throttle channel. Therefore, it is often necessary to remove the valve c...

[0002] There is no such valve in the prior art. The ordinary solenoid valve only has the function of closing and opening, so the structure is very different. Some of its principles are close to the traditional one-way throttle valve. The one-way throttle valve mainly It consists of a valve body and a valve core assembly, the valve body contains a throttle hole, the valve core assembly is inserted into the throttle hole, and the flow path pressure of the valve body is adjusted through the depth of the insertion, while the throttle flow Because the channel is relatively small, it is used for a long time. Objects such as calcium and magnesium ions in the water will crystallize in the throttle channel and block the throttle channel. Therefore, it is often necessary to remove the valve core assembly to deal with the orifice and the valve core assembly. Dirt or crystals, but this needs to be handled with special tools, so it is very inconvenient, and the orifice is relatively deep, which is troublesome to handle
