Abstract
A cold-hot bidirectional water-saving valve comprises a round lower valve body, a spool is arranged in the lower valve body, an upper valve cover is arranged at the upper portion of the lower valve body, a gland is arranged at the center of the upper valve cover, a hand wheel is arranged outside the gland, and the hand wheel is connected with the spool through a screw penetrating through the gland and the upper valve cover. When the valve is closed, the hand wheel starts being rotated, a first water-saving hole and a second water-saving hole are opened first, and cold water not suitable for a bath in a hot water pipe is recovered through a water-saving pipe before being wasted. After all cold water in the hot water pipe is recovered, the hand wheel is continuously rotated clockwise, and the two water-saving holes are closed along with rotation of the spool. Meanwhile, a hot water hole and a water output hole are communicated at the same time, and afterwards, the hot water is used for spraying through a main water output pipe and a shower head. The cold-hot bidirectional water-saving valve has the advantages of being simple in structure, economical and capable of saving energy.

Described cold water hole and hot water hole cross between circle central axis that angle is less than cold water pipe and hot-water line is crossed the angle between circle central axis.
The beneficial effects of the utility model are:
1) structural behaviour: the component of the utility model water-saving valve are all fairly regular and simple geometrical shapies, makes processing technology also very simple, can reduce process costs.
2) usability: due to the utility model simplicity of design, it has good operability, user only need carry out bidirectional operation to of a valve parts just can complete recovery cold water, regulates the process of water temperature.
3) practicability: the utility model can reduce the waste of water resources effectively, the utilization ratio of raising water resources.Under the overall background of the growing water demand of the mankind, there is very high use value.And it is low that it has processing cost, the feature that Safety performance is good, is suitable for spread.
Cold and hot two-way water-saving valve of the present utility model can solve the problem of prior art well; reach the object of effectively utilizing this part water; thereby reduce the waste of water resources, improved water utilization rate, can say that this is a kind of effective measures of the current water crisis of reply.Therefore this water-saving valve has very high use value, because it has good Economy and Security, is suitable for spread again.In today of the growing water demand of the mankind, using water wisely should be everyone responsibility, and therefore the design's water-saving valve is significant to protection of water resources; do from drop; doing from oneself is the design's original intention, derives from life, and reverting to life is the design's core concept.

Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail.
referring to Fig. 1,2,a kind of cold and hot two-way water-saving valve, includes the valve body 1 of lower circle, in lower valve body 1, is provided with spool 2, the top of lower valve body 1 is provided with bonnet 3, bonnet 3 centers are provided with gland 4, and gland 4 outsides are provided with handwheel 5, handwheel 5 by screw pass gland, bonnet is connected with spool.
Between described gland 4 and upper cover valve, be also provided with filler 10 and gasket ring 11, filler is located at gasket ring top, between bonnet 3 and lower valve body 1, is provided with seal ring 12.
Handwheel and spool are connected by screw; Gland is and is threaded with cold water pipe, hot-water line, outlet pipe with lower valve body, lower valve body with bonnet, bonnet.
Referring to Fig. 3,4,5, the outer wall of described spool 2 is provided with osculum 13, water saving holes 1, cold water hole 15, water saving holes 2 16 and hot water hole 17.Described valve body 1 outer wall is provided with cold water pipe 6, hot-water line 7, outlet pipe 8 and saving pipe of water 9.
Referring to Fig. 4, represent the hull-borne before using.Before use, clockwise rotate handwheel, arrive the hull-borne of Fig. 4.Due to the design of hole on spool, start to rotate handwheel from valve closes, what open at first is water saving holes 1 and water saving holes 2 16.Thus, the cold water that is not suitable for having a bath in hot-water line was just just derived and is reclaimed by saving pipe of water before being wasted.In whole drainage procedure, hot and cold water hole is all kept closed.
Referring to Fig. 5, hull-borne when use.Until after the cold water in hot-water line 7 is all recovered, continues up time and rotate handwheel, two water saving holes are by closed along with the rotation of spool.In this simultaneously, hot water hole 17 just supplies people's shower by primary flow pipe with meeting and discussing with osculum 13 conductings simultaneously, hot water afterwards.In to the layout design in hole, make cold water hole and hot water hole's the angle between circle central axis of crossing be less than cold water pipe with hot-water line is crossed the angle between circle central axis, thus the working state shown in the upper figure of appearance.This ingehious design makes water-saving valve simple to operation, and user can arbitrarily regulate water temperature (only needing clockwise and anticlockwise to start to take turns).
Referring to Fig. 6, the central angle of described water saving holes 1, cold water hole 15 hot water holes and water saving holes 2 16 is 12; The central angle of osculum 13 is 24; The center of circle minute of angle 41 of main osculum 13 and water saving holes 14 is spent; The center of circle minute of angle of water saving holes 14 and cold water hole 15 is 70 degree; The center of circle minute of angle of cold water hole 15 and water saving holes 16 is 41 degree; Water saving holes 16 and hot water hole's 15 center of circle minute of angle 13 is spent; The angle of crossing between circle central axis and vertical symmetry axis of crossing circle central axis and hot-water line 7 of cold water pipe 6 is 45 degree
