Coning, middle-end becomes corrugated tube shape in the front end of described telescopic head, and rear end has valve head front end trepanning.
Described valve head comprises valve head front end and valve head rearward end, and wherein the diameter of valve head front end is less than the diameter of valve head rearward end, and valve head front end and telescopic head are combined together, and valve head rearward end and spiro rod rear end are combined together.
Also have a limiting board between described flow adjustment knob and screw rod, this limiting board has restraining groove, guide sleeve has the set screw corresponding with restraining groove at corresponding position.
Also overlapping between described guide sleeve outside and telescopic head has to seal a spacer ring, and sealing spacer ring inside has the cavity of hollow, and inner top surface and the needle of this cavity have gap.
Described screw front end becomes anistree cylinder, has octagon cavity corresponding with it in the middle of flow adjustment knob.
The beneficial effects of the utility model are:
1, the flow of mode to hot and cold water that the utility model adopts screw rod to promote regulates, so relatively traditional regulative mode accurate quick more.
2, the utility model adopt telescopic head front end coning, middle-end becomes corrugated tube shape; In flexible cephalomotor process, remain good sealing effect like this, adopt this structure to adopt the structure of seal ring to have better sealing effect relative to other.
3, sealing spacer ring by increasing by one again between and telescopic head outside at guide sleeve, realizing secondary seal like this, significantly improving the sealing effect of whole thermostatic valve.
4, by increasing a limiting board between flow adjustment knob and screw rod, preventing user from rotating through wide-angle like this, protecting whole mechanism.

Embodiment
Please refer to Fig. 1 to Fig. 2, the thermostatic valve warm water sealing in figure and flow control device, comprise a flow adjustment knob 1, limiting board 2, screw rod 3, valve head 4, needle 5, guide sleeve 6, telescopic head 7.
Flow adjustment knob 1 is common knob, has anistree axle mounting hole 11 in the middle of it.
Limiting board 2 one-tenth planar, in the middle of it, there is screw rod punched out 21, position, both sides of the edge has arc-shaped limit groove 22, this limiting board 2 is fixed together with flow adjustment knob 1, when flow adjustment knob 1 rotates, it also follows rotation, allow when rotating to certain angle, the screw on guide sleeve fixed plate 10 will limit the rotation of this limiting board, and then flow adjustment knob is stopped the rotation.
The leading portion of screw rod 3 has anistree axle construction and forms octagon cylinder, this anistree axle construction is enclosed within the anistree axle mounting hole 11 of flow adjustment knob 1, the neutral position of screw rod 3 is then fixed in the screw rod punched out 21 in the middle of limiting board 2, and inner outer side surface has outside thread.
Valve head 4 has former and later two ends, i.e. valve head front end 41 and valve head rearward end 42; Wherein the diameter of valve head front end 41 is less than the diameter of valve head rearward end 42; Wherein valve head front end 41 is for entangling telescopic head 7, and valve head rearward end 42 is for fixing needle 5 and coordinate with screw rod 3.Valve head front end 41 front end is tapered, corresponding with the interior shape of telescopic head 7 like this.The outer annular face of valve head rearward end 42 also has upper and lower two needle mounting holes 421, needle 5 to be just enclosed within this needle mounting hole 421 and to be on the outside thread of screw rod 3 equally, just can drive needle 5 to-and-fro motion like this when the outside thread of screw rod 3 rotates.
It is outside that guide sleeve 6 is enclosed within valve head 4, and this guide sleeve 6 has needle locating slot 61 with needle 5 corresponding position, and this guide sleeve 6 front end has opening and runs through guide sleeve 6 for valve head front end 41 and valve head front end 41 and telescopic head 7 are combined together.In order to make to seal between guide sleeve 6 and telescopic head 7, can increase a sealing spacer ring 8 between both, sealing spacer ring 8 inside has the cavity of hollow, and inner top surface and the needle 5 of this cavity have gap, such needle 5 just can have living space and move in sealing spacer ring 8, can not be blocked by it.In order to be that this guide sleeve 6 is fixed on spool, this guide sleeve 6 can be fixed on a guide sleeve fixed plate 10.
Needle 5 is common rod-like structure, and its main effect is under the drive of screw rod 3, drive valve head 4 to move, thus drives telescopic head 7 horizontal motion.
Telescopic head 7 is flexible member, and rubber or silica gel can be adopted to make, and its front end is coning for shutoff hot water outlet, middle-end becomes corrugated tube shape, rear end has valve head front end trepanning 71, adopts the design of bellows uniqueness, thus make whole mechanism obtain good sealability at this.In order to make telescopic head 7 keep sealing with sealing spacer ring 8, a seal ring 9 can be increased between them.
