Abstract
An electromagnetic valve having a flow control function. A valve body has an inlet, an outlet, a valve chest, and a valve plate contained inside the valve chest. The valve plate opens and closes a valve seat using a movable core in order to control the flow rate of water and to prevent backflow. A first channel is disposed inside the outlet. A flow control means, configured as a single unit, is inserted into the outlet, and includes a mover for opening and closing a flow of water by being detached from and brought into contact with the first channel, a stator disposed coaxially with the mover. The stator allows the mover to be elastic and freely movable using a restoring element. A flow rate control element is supported on the stator, and has a predetermined interval from the stator to form a second channel.
Claims5
An electromagnetic valve having a flow control function, comprising:
- a valve body, wherein the valve body comprises:
- an inlet through which water flows in;
- an outlet through which the water flows out;
- a valve chest in a central portion of the body;
- and
- a valve plate contained inside the valve chest, the valve plate opening and closing a valve seat depending on opened and closed states using a movable core, which is actuated by magnetic force from an electromagnet, in order to control a flow rate of water and to prevent backflow,
- a first channel for water, disposed inside the outlet;
- and
- a flow control means inserted into the outlet, wherein the flow control means is configured as a single unit, and comprises:
- a mover for opening and closing a flow of water by being detached from and brought into contact with the first channel;
- a stator disposed coaxially with the mover, the stator allowing the mover to be elastic and freely movable using a restoring element;
- and
- a flow rate control element supported on the stator, the flow rate control element having a predetermined interval from the stator to form a second channel,
- wherein, when supply of water, in which the mover of the flow control means keeps the first channel in an opened state in response to pressure with which water is supplied, is stopped, the restoring element causes the mover to automatically restore an original position thereof so that the first channel stays in a closed state, and the flow rate control element is deformed in response to changes in the pressure with which water is supplied, thereby varying the area of the second channel.
