Abstract
A balance valve is provided with an asymmetric structure. When the dual-temperature ceramic valve is switched to cold water supply modes, and the hot water line is blocked to make a moveable spool abutted towards a first lateral end wall of a holding space, a cold water channel can thus be formed between the cold water opening of a fixed valve pipe and a second end of the moveable spool with the setting of the asymmetric structure. Hence, cold water supply can maintained. When the hot water line is blocked, the cold water supply function of the balance valve of the present invention could still be maintained for improved convenience and applicability.
Claims4
A valve apparatus comprising:
- a dual-temperature ceramic valve having a holding space, said holding space having a cold water inlet and a hot water inlet arranged in spaced relationship to each other at a bottom of said holding space, said holding space having a cold water outlet and a hot water outlet in spaced relationship to each other at a top of said holding space, said holding space having a first lateral wall and a second lateral wall at opposite ends thereof;
- a fixed valve pipe having a transverse hollow pipe with a first end corresponding to said first lateral wall and a second end corresponding to said second lateral wall, said fixed valve pipe having a cold water opening connected to said cold water inlet and a hot water opening connected to said hot water inlet, said first end connected to said hot water outlet, said second end connected to said cold water outlet;
- a movable spool transversely assembled into said fixed valve pipe and transversely movable therein, said movable spool having a first end and a second end, said first end of said movable spool being recessed so as to form a hot water slot, said second end of said movable spool being recessed to form a cold water slot, said hot water slot being separated by a partition from said cold water slot, said hot water slot having a hot water punch hole connected to said hot water opening of said fixed valve pipe, said cold water slot having a cold water punch hole connected with said cold water opening of said fixed valve pipe;
- and
- an asymmetric structure extended asymmetrically by said first end and said second end or by said first end and said second end of said movable spool or by said hot water opening and said cold water opening of said fixed valve pipe or by said hot water punch hole and said cold water punch hole of said movable spool, said ceramic valve being switchable to a cold water supply mode so as to block a hot water supply line in order to make said movable spool abut said first lateral wall of said holding space so as to form a cold water channel between said cold water opening of said fixed valve pipe and said second end of said movable spool.
