Embodiment

Below the utility model is explained through specific embodiment and conjunction with figs..

As shown in Figure 1; One three-way valve includes body 1; Inside moulding one cavity volume 11 of this body 1, and be provided with a water intake 12 and two

bleeders

13,14 forms in the cavity volume 11 should water intake 12 and the water channel of two

bleeders

13,14; Water intake 12 is connected with water main to insert the water source, and two

bleeders

13,14 are vertically and connect the water terminal respectively to laying.

The two-way three-way valve water route switching construction of the utility model is arranged in the cavity volume 11 of this three-way valve body 1; Be positioned on the water channel that is communicated with water intake 12 and two

bleeders

13,14; Mainly comprise guide pin bushing 2, unsteady stopper 3, mandrel 4 and rotor 5 and button 6; The stopper 3 that floats cooperates mandrels 4 and rotor 5 to be movably set in the guide pin bushing 2, and mandrel 4 receives button 6 to drive interlock rotors 5 and drive the stopper 3 that floats to move two

bleeders

13,14 that cooperate with water channel with selectivity conducting body.

Wherein, said guide pin bushing 2 is fixed in the cavity volume 11 of body, and is as shown in Figure 2; This guide pin bushing is the sleeve of a hollow; One end is provided with perforation 21, and it is uncovered 22 that the other end is made as, and the bottom of guide pin bushing forms cover seat 23 around perforation 21; The inwall circumferencial direction of cover seat 23 is evenly laid three spacing ribs 231, and the sidewall of guide pin bushing is provided with open-work 24; One end of unsteady stopper 3 is to sinking into a counterbore 31; This end stretches in the guide pin bushing 2 the cover seat 23 that wears guide pin bushing 2 by counterbore 31, and the stopper 3 that floats movably is arranged in the guide pin bushing, and the other end of the stopper 3 that floats is a water-stopping end 32; Cooperate with a spring 7 outside this water-stopping end protrusion guide pin bushing 2; One end of this spring 7 is resisted against on the water-stopping end 32 of the stopper that floats, and the other end acts on the inwall of body cavity volume 11, and the outer wall of the stopper 3 that floats again forms necking down 33 at the middle part; 5 cooperations are movably arranged in the cover seat 23 of guide pin bushing said mandrel 4 with rotor; The perforation 21 of the one end protrusion guide pin bushing of mandrel 4 is connected with button 6; Receive the driving of button 6, several ratchets 41 of moulding on the other end, the top of each ratchet 41 is the conical surface; Be separated with short slot 42 between between the two adjacent ratchets 41, the middle part of mandrel is provided with axis hole 43 again; Rotor 5 cooperates with mandrel 4 and interlock; One end of this rotor 5 stretches in the axis hole 43 of mandrel 4; The other end top is used for the bottom of unsteady stopper counterbore instead, and the middle part is provided with grinding tooth 51 corresponding with mandrel ratchet 41 quantity and that cooperate, and the end face of each grinding tooth 51 is made as the inclined-plane; And two 51 of adjacent grinding tooths replace is provided with fluting 52 or restraining groove 53 (referring to Fig. 3,3A, 3B), shown in figure, is preferable enforcement evenly to be provided with three groups.

It below is the two states in the utility model practical implementation.

State one: pressing button 6 promotes mandrel 4 and axially moves inward; The conical surface at mandrel ratchet 41 tops is cooperated with the inclined-plane formation of rotor grinding tooth; The angle of ordering about a grinding tooth of rotor 5 rotations overcomes spring 7 simultaneously and drives the stopper axial displacement of floating, and loosens button, mandrel 4, rotor 5 and the 3 axial travelling backwards under the restoring force effect of spring 7 of stopper of floating; The short slot 42 that makes the rib of guide pin bushing cover seat inwall pass mandrel falls into the fluting 52 of rotor; To float this moment be in after stopper 3 moves axially on the uncovered position of water-stopping end 32 sealing guide pin bushings, blocked the water channel that water intake 12 is communicated to bleeder 13, makes bleeder 13 for closing water state; As shown in Figure 4, the water of this moment is to be got into through bleeder 14 by water intake 12 to flow out.

State two: as shown in Figure 5; Pressing button 6 promotes mandrels 4 to be ordered about angle that rotor 5 rotates a grinding tooth again and overcomes spring 7 simultaneously and drive the stopper axial displacement of floating; Loosen button; The mandrel 4, rotor 5 and the stopper 3 axial travelling backwards under the restoring force effect of spring 7 of floating, the short slot 42 that makes the rib of guide pin bushing cover seat inwall pass mandrel falls into the restraining groove 53 of rotor, is on the position of water-stopping end 32 sealing bleeders 14 water channels after the stopper 3 that floats this moment moves axially; Make bleeder 14 for closing water state; Like arrow indication among Fig. 5, the water of this moment is by necking down 33 and gap between the guide pin bushing entering guide pin bushing of water intake 12 through the stopper 3 that floats, and flows out through the 24 connection bleeders 13 of the open-work on the guide pin bushing sidewall.

Adopt said structure; The utility model drives mandrel 4 through button 6 and does axial moving with rotor 5 and the unsteady stopper 3 of drive; Utilize cooperating of mandrel 4 and rotor 5 simultaneously; Selection make on the guide pin bushing 2 cover seat spacing rib and epitrochanterian fluting 52 or restraining groove 53 one of them cooperates, confirm the position that unsteady stopper 3 is axial with this, water-stopping end through unsteady stopper and water channel corresponding matching are with two

bleeders

13,14 of selectivity conducting body.
