Detailed description of the invention
As shown in Figure 1, 2, this utility model includes radiator pipe 5 that engine tube 1 carries out heat exchange with engine tube 1, the valve block 4 that is arranged between engine tube 1 with radiator pipe 5 is connected with valve block 4 and for the drive mechanism 3 of control valve block 4 folding and the control motor 2 that is in transmission connection with drive mechanism 3；
Valve block 4 include the housing 13 being arranged in engine tube 1, the upper valve body 11 being arranged on housing 13 inner chamber top, be arranged on the lower valve body 10 below upper valve body 11, be arranged between upper valve body 11 with lower valve body 10 seal hole 12 and be arranged in housing 13 inner chamber and with seal the corresponding spool 9 in hole 12；Being provided with the upper channel 15 of inlet communication with radiator pipe 5 in upper valve body 11 side, be provided with the lower channel 14 connected with engine tube 1 on lower valve body 10, spool 9 is in transmission connection with drive mechanism 3.Valve block 4, certainly as malformation, can use the common structure such as electromagnetic valve or hand-operated direction valve.Drive mechanism 3 can be air cylinder driven, electric pushrod or crankshaft-link rod etc..
Further, drive mechanism 3 includes the driven gear 7 that the driving gear 6 being in transmission connection with the output shaft controlling motor 2 engages and the cam 8 being in transmission connection with driven gear 7 with driving gear 6；Cam 8 top is corresponding with spool 9 lower end of valve block 4, is provided with spring 16 between the roof of the upper surface of spool 9 and upper valve body 11.
Further, driven gear 7 and cam 8 coaxial transmission.Simplify structure.
Further, the lower surface of spool 9 is arc-shaped structure.Reduce and drive resistance, reduce noise, improve response speed.
Further, control motor 2 to be electrically connected with for monitoring the temperature detect switch (TDS) of coolant in radiator pipe 5.Use the coolant temperature in temperature detect switch (TDS) induction generator pipe 1, it is achieved automatically control, thermometer monitors or Non-follow control can be used to control the break-make of motor 2.
Further, spool 9 it is provided with and seals the inverted cone surface that hole 12 is in sealing contact.Alleviate spool 9 runs resistance jointly.
