1. An adjustable jet valve, comprising: a valve body, provided with a cold water port, a hot water port and a mixing outlet for mixed water disposed thereon;a nozzle disposed in said valve body, having a cold water inlet communicated with a cold water passage of a valve through said cold water port,
1. An adjustable jet valve, comprising: a valve body, provided with a cold water port, a hot water port and a mixing outlet for mixed water disposed thereon;a nozzle disposed in said valve body, having a cold water inlet communicated with a cold water passage of a valve through said cold water port, and a cold water outlet;a needle assembled in said nozzle, forming a cold water inflow space with an inner cavity of said nozzle, and forming a cold water jetting outlet with said cold water outlet; anda throat pipe disposed in connection with said mixing outlet of said valve body, adapted for discharging mixed water;a rotatable member rotatably disposed in said valve body in a sealing manner; said rotatable member being axially movable relative to said nozzle and fitted therewith through an axially adjusting mechanism, so as to displace said nozzle in the axial direction of said needle by the rotation of said rotatable member;wherein said needle is unmovable in the axial direction of said adjustable jet valve; said nozzle is movable in the axial direction of said adjustable jet valve; and fluid flow rates of said cold water inflow space, said hot water port and said cold water jetting outlet are adjusted simultaneously through axially adjusting said nozzle; andwherein said rotatable member is in connection with said needle, so as to actuate said needle to rotate simultaneously; said valve body is coordinated with said nozzle through a rotation limiting part, adapted for stopping said nozzle to rotate relative to said valve body when said needle is rotated by said rotatable member. 2. The adjustable jet valve according to claim 1, wherein said axially adjusting mechanism comprises an internal thread formed on said nozzle and an external thread formed on said rotatable member and adapted for being engaged with said internal thread; and the stroke for engagement of said internal thread and said external thread is no less than the working stroke of said nozzle. 3. The adjustable jet valve according to claim 1, wherein said rotation limiting part is a polygonal end portion formed on said nozzle, and the inner wall of said valve body is fitted therewith. 4. The adjustable jet valve according to claim 1, wherein said rotation limiting part comprises a flange and/or a guiding groove circumferentially arranged in the external wall of said nozzle, and a guiding groove and/or a flange axially arranged in the inner wall of said valve body fitted therewith. 5. The adjustable jet valve according to claim 4, wherein said cold water inlet and said cold water outlet of said nozzle have a pair of circumferential flanges formed therebetween extending radially outward, and said circumferential flanges allow a sealing element to be disposed therebetween, and a hot water segment of said nozzle located between said circumferential flanges and said cold water outlet is able to be communicated with a hot water passage of the valve. 6. The adjustable jet valve according to claim 1, wherein said throat pipe is assembled in said valve body formed said hot water port thereon in connection with the hot water passage and said throat pipe, and said throat pipe comprises a path pipe and an expanding pipe. 7. The adjustable jet valve according to claim 6, wherein said path pipe has an inner diameter between 5 mm and 14 mm, and the length of said path pipe is 5 to 8 times of said inner diameter. 8. The adjustable jet valve according to claim 6, wherein said expanding pipe has an expanding angle (β) between 5° and 15°. 9. The adjustable jet valve according to claim 8, wherein said expanding pipe is expanding gradually from its small end to its big end. 10. The adjustable jet valve according to claim 9, wherein said expanding pipe expands in three steps manner. 11. The adjustable jet valve according to claim 1, wherein said needle comprises a needle body and a conical portion located on one end of said needle body and coordinated with said cold water outlet of said nozzle; said needle body is circumferentially provided with a supporting member so as to allow outer surface of said supporting member to coordinate with the inner cavity of said nozzle, in order to limit the position of said needle body and to form a fluid passage on said supporting member, as said needle is disposed inside said nozzle. 12. The adjustable jet valve according to claim 11, wherein said supporting member comprises a plurality of ribs circumferentially and uniformly arranged around said needle body in the axial direction, and said fluid passage is formed between said ribs. 13. The adjustable jet valve according to claim 12, wherein said rib comprises a first rib part and a second rib part; said first rib part is arranged towards said cold water inlet of said nozzle and has a radial dimension smaller than that of said second rib part, so as to coordinate with said inner wall of said nozzle to form said fluid passage, and the outer surface of said second rib part is fitted with the inner cavity of said nozzle. 14. The adjustable jet valve according to claim 12, wherein the number of said ribs is three or four or five or six; the sum of the cross section of all fluid passages formed between said ribs is larger than the cross section of said cold water outlet of said nozzle. 15. The adjustable jet valve of claim 11, wherein a water pressurizing and mixing segment is disposed between said conical portion and said supporting member of said needle body, and the shape of said water pressurizing and mixing segment is a cylinder. 16. The adjustable jet valve according to claim 15, wherein the diameter of said water pressurizing and mixing segment is larger than, equal to or slightly smaller than the diameter of a spout of said nozzle. 17. The adjustable jet valve according to claim 16, wherein the diameter of said conical portion declines from its root to its front end, the taper of which is between 10° and 150° and the length of said conical portion is smaller than or equal to the movable stroke of said nozzle. 18. The adjustable jet valve according to claim 1, wherein when said nozzle is displaced in the axial direction of said adjustable jet valve, the pressure of cold water of said cold water inlet disposed thereon is always consistent with the pressure of cold water of said cold water port disposed on said valve body.
