Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In accompanying drawing 1---4, valve pocket 10 is fixed on the lower end of body 15 by spool locking nut 9, and the water port 17 that is connected with the water chamber 31 of body 15 is arranged on the wall of valve pocket 10, and shift fork valve rod 8 is inserted in the valve pocket 10.Two shift forks of shift fork valve rod 8 are contained in respectively and rotate in two corresponding on the porcelain heart sheet 18 shift fork holes 22, rotate on the porcelain heart sheet 18 and have tank 11; The fixedly porcelain heart sheet 13 that is provided with water passage hole 12 and positioning block 21 is fixed in the valve pocket 10 by locating slot 20, and fits tightly with rotation porcelain heart sheet 18; T RunddichtringO 14 is positioned at the fixedly top of porcelain heart sheet 13.Fixedly position, quantity, shape and the size of water passage hole 12 should be corresponding with the mistake tank 11 on rotating porcelain heart sheet 18 on the porcelain heart sheet 13, and what the utility model adopted is two V-type grooves and two V shaped holes of symmetry.The afterbody of shift fork valve rod 8 also is set with four ratchet 3 and handles 1 that ratchet is uniform, and ratchet 3 connects by key 19 and shift fork valve rod 8, and finger 2 is installed in the handle 1, and spring 32 is housed on the finger 2.In order to prevent handle 1 axial float, screw 5 is fixed on back-up ring 4 bottom of shift fork valve rod 8.Afterbody at valve pocket 10 also fixedly is equipped with non-return key seat 7, and the non-return pin 6 that is with spring 32 is installed in this.In order to seal better, be provided with two O RunddichtringOs 30 in the stage casing of shift fork valve rod 8; In order to wash one's hands conveniently, above body 15, also soap box 16 can be set.

In accompanying drawing 5, ratchet 25 on the shift fork valve rod 8 is provided with the clutch tooth for end face, and four clutch-type ratchets that ratchet is symmetrically distributed, the end face of the handle 23 on the shift fork valve rod 8 has the clutch tooth that can match with ratchet 25, spring 24 is installed on the shift fork valve rod 8, and between handle 23 and back-up ring 4.

In accompanying drawing 6, the check device in the non-return key seat 7 can also be made of the spring sheet 27 that a swing non-return pin 28 and an end are fixed on the non-return key seat 7, the other end is pressed on the swing non-return pin 28 that is enclosed within on the bearing pin 26.

During unlatching, handle 1 is rotated along clockwise direction, finger 2 stretches out and withstands the ratchet of ratchet 3 under the effect of spring 32, and this moment, non-return pin 6 was inoperative.Ratchet 3 drives by key 9 and shift fork valve rod 8 and rotates 18 rotations of porcelain heart sheet, the tank 11 of crossing that rotates on the porcelain heart sheet 18 overlaps gradually with water passage hole 12 on the fixing porcelain heart sheet 13, and tap water is flowed through water-inlet cavity 29, water passage hole 12, mistake tank 11 and water port 17 from water chamber 31 outflows; When water passage hole 12 water flow when crossing tank 11 and overlap fully reaches maximum, at this moment handle 1 has rotated 90 °, just in time is in the faucet outlet below, thereby realizes the purpose of flushing faucet handles.When closing, handle 1 rotated counterclockwise more than 90 ° it is resetted, this moment, the non-return pin 6 worked, and then clockwise rotated.Under the drive of shift fork valve rod 8, to cross tank 11 and stagger gradually with water passage hole 12, current reduce gradually until closing fully; This moment, handle 1 just in time was in the faucet outlet below.During washing,, handle 1 can be rotated counterclockwise several angle and get final product if need not wash handle.
