[Effect of device]

 Since the present invention is configured as described above, the following effects are produced.

The valve device of the present invention differs from the conventional valve device in that the valve rod and the operating part for operating the valve body from the valve box are not exposed, which is a major difference in form. The elastic valve element and the valve seat face inwardly and can be fixed or screwed in series to the fluid passage. By using this valve device, a new form of fluid passage opening / closing and flow regulating device is conceivable. Is a typical example.

A shower head in which the valve device of the present invention is fixed to the water discharge port of the shower head and the water discharge member is screwed to the movable cylinder is conceivable. The shower head is used for bathrooms and hair wash vanity tables. Can be used everyday When using a shower in general, first adjust the water discharge temperature (hot water temperature) of the hot and cold water mixer with shower using the hot water and water flow rate control knob (or hot water thermostat knob). After that, it is thought that shower water will almost always be left on while washing your hair and body. If you use this shower head, you can easily discharge water, stop water, and adjust the flow rate as needed. The water-saving effect is great, the valve body can be easily replaced like a general faucet, and the shower head can be replaced with only the shower head part of a device having a shower facility. You can change it.

The valve device of the present invention can be screwed as an intermediate valve device in the middle of the fluid flow path pipe to open / close the fluid flow path and adjust the flow rate. The form of the valve device is different from the conventional one. The valve body operating portion is not exposed from the valve box. Therefore, by using the valve device as the intermediate valve device of the fluid passage, it can be compactly installed and stored.
