Description

Electromagnet water supply valve

The present invention relates to an electromagnet feed valve for controlling the water supply of water, and more particularly, to an electromagnet feed valve for stabilizing the flow of water generated on the outlet side.

In general, an electromagnet valve has a fuselage having an inlet and an outlet for outflow of water from the water supply pipe, and is separated up and down by a diaphragm between the inlet and outlet of the fuselage. It is equipped with the first valve seat to be opened and closed by a valve driven by a movable iron operated by an electromagnet in the upper space, and the second valve seat to be opened and closed by a diaphragm in the lower space. To control the water supply.

However, the water flowing into the inlet side of the electromagnet valve is unstable in the process of supplying water to the outlet side, causing noise and leakage.

In other words, the water flowing out for water supply to the outlet part generates turbulence as the hydraulic pressure increases and decreases according to the fluctuation of the water supply pipe of the water supply pipe, which causes noise in the water supply.

In addition, the adhesion between the diaphragm and the second valve seat, which is an opening / closing member for supplying or blocking the water flowing into the inlet part, is reduced due to water moss, etc., which causes leakage.

The present invention has been made to solve the above problems, its purpose is to induce turbulence while branching the flow of water on the water outlet side to reduce the flow rate of the water, incomplete turbulence generated on the water outlet side by the water pressure To provide an electromagnet feed valve to stabilize the flow of.

Another object of the present invention is to provide an electromagnet water supply valve in which water moss or the like is removed at the time of opening and closing operation to prevent water leakage in a part of opening and closing the flow path of water in order to control the water supply of water.

The present invention for realizing the above object is provided with a water inlet is provided on one side to the water supplied from the water supply pipe, the other side has a body having a water outlet for outflow of water to the use side, the middle of the body of the body of the water inlet and outlet diaphragm A solenoid water supply valve having a valve chest having first and second valve seats which are separated by an upper and a lower side and opened and closed by a valve driven by an electromagnet, the body having an inner diameter fitted to the water outlet side to form a flow of water. And a plurality of ribs provided on the inner diameter of the body to form a friction surface of the water while branching the flow of water, and connected to the ribs at the center of the inner diameter so as to induce the flow of water to the inner diameter of the ribs. The sound pipe made of guide protrusions has a characteristic configuration.

The diaphragm is provided with a protrusion making contact with an inner edge of the second valve seat, wherein the contact surface between the protrusion and the inner edge of the second valve seat forms an inclined surface.

According to the present invention, a leak source such as water moss adsorbed on the contact surface of the diaphragm and the second valve seat is removed in the process of opening and closing the flow path of the water by the electromagnet, thereby achieving stable water supply.

In addition, as the water is discharged through the water outlet side, it is decelerated by the frictional force while passing through the flow path in the relatively narrow sound pipe for the single discharge path of the water, thereby stabilizing the flow of turbulence and minimizing the noise during water supply. have.
