Below in conjunction with the accompanying drawings this utility model is further described.
Medical blood-qi circulating instrument electromagnetic pilot head as shown in Figures 1 to 4, including base 1 and base 1
The end cap 2 being connected, the first guide assembly being arranged on base 1, be formed between base 1 and end cap 2
Valve pocket 3, base 1 is respectively arranged with the input port 11 and delivery outlet 12 connected with valve pocket 3, valve pocket 3
Inside it is respectively arranged with inner sleeve 13 and piston 14, end cap 2, piston 14, input port 11, inner sleeve 13 and defeated
Outlet 12 is sequentially arranged, and piston 14 is fixedly connected with the piston rod 15 coaxial with inner sleeve 13, piston rod
The free end of 15 is provided with taper enlarging 131 towards inner sleeve 13, one end of inner sleeve 13 adjacent piston bar 15,
The free end of piston rod 15 is provided with the round table surface 151 corresponding with taper enlarging 131, piston rod 15
Also support between free end and base 1 and be provided with back-moving spring 16.
First guide assembly includes first guide bracket 41 and plunger tube 42, and plunger tube 42 is by first guide bracket 41 and base 1
Fixing connection, the inside of plunger tube 42 is fixedly installed static iron core 43, is movably set with actively iron core 44,
Base 1, first guide bracket 41, it is formed with first guide cavity 45 between plunger tube 42 and static iron core 43, in base 1
It is separately provided for connecting the air inlet runner 17 of gas source interface, for controlling the workflow of piston 14 action
Road 18, air inlet runner 17 and platform flow channel 18 all communicate with first guide cavity 45, the actively bottom of iron core 44
Seal in being inserted into first guide cavity 45 and with air inlet runner 17 and coordinate, actively the bottom of iron core 44 and first guide bracket
Support between 41 and be provided with actively iron core spring 46.
Actively the internal activity of iron core 44 is provided with secondary dynamic iron core 47, and the bottom of static iron core 43 is inserted into master
Moving iron core 47 corresponding matching in dynamic iron core 44 and with pair, secondary dynamic supporting between iron core 47 and static iron core 43 sets
Having secondary dynamic iron core spring 48, actively the bottom sidewall of iron core 44 is provided with the bypass connected with first guide cavity 45
Hole 441, the bottom of secondary dynamic iron core 47 is provided with the pair coordinated with by-pass prot 441 sealing and moves iron core sealing gasket
471.The outside of plunger tube 42 is arranged with main coil assembly 49 and secondary coil assembly 50 the most successively,

Now piston 14 overcomes the elastic force of back-moving spring 16 to move towards inner sleeve 13 direction under gas pressure effect,
But again due to the most secondary dynamic iron core 47 action so that the gas pressure entering platform flow channel 18 is relative
It is less, therefore piston 14 is only capable of moving to half-travel position, although now input port 11 is with delivery outlet 12 still
In the conduction state, but between the round table surface 151 of piston rod 15 and the taper enlarging 131 of inner sleeve 13
Radial clearance reduce so that the output flow of delivery outlet 12 correspondingly reduces；
When main coil assembly 49 is energized, see Fig. 4, under the effect of electromagnetic attraction so that actively ferrum
Core 44 and pair move the equal action of iron core 47, the gas in air inlet runner 17 through first guide cavity 45 completely into work
Making in runner 18, piston 14 pressure experienced increases so that piston 14 continues to overcome back-moving spring 16
Elastic force and move to full stroke position, the now taper of the round table surface 151 of piston rod 15 and inner sleeve 13
Enlarging 131 is in sealing contact, and is in the state of being closed, delivery outlet 12 between input port 11 and delivery outlet 12
Discharge without fluid.
In sum, the on or off of medical fluid during utility model works, can not only be realized, with
Time can also control and regulate the output flow of medical fluid, diverse in function, it is possible to have the most in real time
Effect meets actually used demand.This utility model structure arranges advantages of simple, easy to operate.
The outer wall of inner sleeve 13 is arranged with reinforcing ring 19, is effectively increased inner sleeve 13 by arranging reinforcing ring 19
Positional stability.It is embedded with inner sleeve sealing ring 132 between outer wall and the base 1 of inner sleeve 13, improves
Sealing within base 1.In order to make axiality when piston rod 15 moves higher, fixing in base 1
Being provided with and the guide holder 20 of piston rod 15 corresponding matching, guide holder 20 is positioned at piston 14 and input port
Between 11.
It is embedded with piston rod packing circle 152, when piston 14 runs to full in the round table surface 151 of piston rod 15
During stroke, can be effectively improved plugging effect by piston rod packing circle 152, service behaviour is more stable.
The free end of piston rod 15 axially extends and is provided with newel 153, and back-moving spring 16 is sheathed on newel
The outside of 153, newel 153 effectively strengthens the position degree of back-moving spring 16.In order to improve actively ferrum
The core 44 plugging effect to air inlet runner 17, actively the bottom of iron core 44 is embedded with and air inlet runner 17
Seal the active iron core sealing gasket 442 coordinated.
The axially disposed exhaust passage 431 having with atmosphere of static iron core 43, the top of secondary dynamic iron core 47
It is provided with the pair coordinated with exhaust passage 431 sealing and moves iron core sealing member 472, secondary dynamic iron core sealing member 472
And pair is moved and is provided with inner spring 473 between iron core sealing gasket 471, and actively the sidewall of iron core 44 is provided with flat
Weighing apparatus hole 443.When piston 14 resets under the driving of back-moving spring 16, the gas in first guide cavity 45 depends on
Secondary it is expelled to air through balance pipe 443, exhaust passage 431.
