[Industrial applications]

 The present invention relates to a water-saving piece for tap water.

[0002]

[Prior art]

 In the summer of 1994, water shortages nationwide became a major social problem, and even now, people are clamoring for water conservation in many areas. Conventionally, as a water-saving coma for tap water, there has been a decompression throttle valve system for suppressing the amount of flowing water. However, with this throttle valve method, when a small amount of water is squeezed out and a small amount of water is squeezed out, the water flutters loosely, which does not give the user a sense of satisfaction and tends to discharge water a lot.

In restaurants and Chinese restaurants and other kitchens, there is a place where tap water is fully opened to release tap water all day long. In large hotels, the water bill is 20 million yen a month, and there is a strong demand for water conservation.

In the cock-type water faucet, since the water-saving top can be attached to the joint portion, the water discharged from the small water passage diffuses through the long flow path and is discharged. However, a lever-type water faucet for mixing hot and cold water requires a water-saving piece to be installed in the foam at the tip of the flow path, so if it comes out directly from a small water passage hole, it is directly affected. Has become.

[0005]

[Problems to be solved by the device]

 In view of the above circumstances, the present invention can be used for a lever-type water faucet for mixing hot and cold water, and when the water discharge amount is saved, the water is diffused and a high flow velocity can be maintained. The purpose is to provide an inexpensive water-saving valve.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a disc-shaped mounting disc part having a plurality of water passage holes penetrating in the axial direction, and a conical cylinder integrally connected to the inlet side of the mounting disc part. In the water-saving piece installed at the tip of the flow path of the water faucet, which comprises a cylindrical inlet diffusion cylinder and a cylindrical cylindrical outlet guide cylinder that is integrally connected to the outlet side of the mounting disk, A plurality of spiral blades are integrally connected in the axial direction to the outer peripheral edge of the outlet side of the outlet and the outer surface of the outlet guide cylinder, and a spiral flow is generated by the spiral blades with respect to the water discharged from the water passage hole. It constitutes a water-saving piece characterized by being able to occur.

[0007]

[Work]

 Since the present invention is configured as described above, water is discharged only from the water passage hole, so at least 10% or more of water can be saved. In addition, if a number of bottomed grooves are provided in the mounting disk in advance, and if necessary, these grooves can be post-processed to pass through as water passage holes, so that the water-saving piece can also serve as a water-cooling piece even if the increase in water volume is desired. You can

When water is discharged from the water passage hole, even if the amount of water decreases with respect to the same pressure, the flow velocity can be increased, and discharge can be performed without changing the appearance. However, a lever-type water faucet for mixing hot and cold water requires a water-saving piece to be installed in the foam at the tip of the flow path, so if water comes out from a small water passage, the water cannot diffuse. Therefore, if water is discharged through the spiral blade, a swirl flow is generated and the water can be diffused.
