It is interior, outwardly protruding outlet nozzle 313 is equipped on the side wall of pressure control valve seat, outlet nozzle is connected by tracheae with vacuum noz(zle) 12
It is logical；Gas spring is placed on the demarcation plate in gas control space, from the top edge of pressure control valve seat along pressure control valve seat
The down-set locating slot 314 of inner wall；Aperture, which is equipped with, along the central axis of stop bit lid 35 is greater than or equal to diameter of piston rod
The stop bit flange to lower process, the inner hole shape of stop bit flange and pressure control valve seat is arranged along stop bit lid bottom wall edge in centre bore
Cooperate at yin-yang, the outer diameter of stop bit lid is greater than the diameter of bore of pressure control valve seat；The top of piston head is fixed on piston rod
On bottom wall, outwardly protruding positioning key 38 is set close to the side wall of piston rod in piston head, so that piston head is in gas control space
When moving up and down, positioning key 38 is inserted into locating slot 314 and moves up and down along locating slot, prevents piston head from rotating, and limit
The amplitude that piston head moves up and down；The top of piston rod is passed through to the centre bore of stop bit lid from stop bit flange one end of stop bit lid,
Button is fixed on by piston rod part by fixed screw again, the end of piston head is downwardly into pressure control valve seat, it is fixed to make
Position key enters in locating slot, and stop bit lid is screwed in pressure control valve seat top entry by being located at the external screw thread of stop bit flange outer wall
Internal screw thread on, be fixed on stop bit lid on pressure control valve seat top, the end of piston head resists gas spring.
As shown in fig. 7, the connecting hole 39 being made of the transverse tube interconnected and a longitudinal tubule (L tubule) is equipped on piston head,
The outlet side of the connecting hole is located on the piston head side wall below positioning key, and inlet end is located on the bottom wall of piston head, indulges
Pipe is arranged along the central axes of piston head, transverse tube and longitudinal tubule (L tubule) vertical connection, make connecting hole by the concatenation hole on demarcation plate always with
The connection of air pressure packet.
Push button moves down piston head, and when the lower end surface of positioning key resists the bottom wall of locating slot, piston head is not
It can move still further below, at this moment, the outlet side of connecting hole is connected to outlet nozzle.
When not pressing lower button, the outlet side of connecting hole is located above the inlet end of outlet nozzle, and the two is not connected to;Gas spring
Diameter be less than piston head diameter；More than one airflow hole is equipped on the outer wall below attachment base external screw thread, it is described
Gap between airflow hole and attachment base and air pressure packet is connected to；Between the outer wall of the piston head and the inner hole of pressure control valve seat
Tight fit is formed, piston head can be moved up and down along pressure control valve seat inner hole central axes under the effect of external force.
Piston head outer wall above connecting hole outlet side is equipped with upper seal groove, and upper seal is placed in seal groove,
Piston head outer wall below connecting hole outlet side sets gradually the middle seal groove and lower seal groove cavity parallel with upper seal groove, in it is close
Seal is placed in middle seal groove, and lower seal is placed in lower seal groove cavity.
As shown in Fig. 2, when not pressing lower piston, the outlet side of the connecting hole of the piston head, upper seal and in
Sealing ring is all located above the inlet end of outlet nozzle, and lower seal is located at below the inlet end of outlet nozzle.
As shown in figure 4, the upper seal is located above the inlet end of outlet nozzle, middle sealing ring when pressing lower piston
It is located at below the inlet end of outlet nozzle with lower seal, connecting hole is connected with outlet nozzle.
In the application, it when the first liquid flow incident flow mixer in the first liquid container, is flowed in jet mixer
Make to generate negative pressure in vacuum noz(zle) and imbibition nozzle, this is, by lower piston, piston compresses gas spring, makes the connecting hole on piston head
Outlet side, outlet nozzle be connected with vacuum noz(zle), so that pressure control valve seat is in negative pressure state, to overcome the pressure of gas spring
Power keeps the position of piston head constant, continues that connecting hole is kept to be connected to outlet nozzle, the negative pressure in vacuum noz(zle) is further through pressure control
Valve is transmitted in air pressure packet, make air pressure packet fold shrink overcome the pressure of hydraulic spring grease cup to be lifted up needle-valve, make needle-valve with
Gap is generated between needle seating, imbibition nozzle is connected to liquid inlet port, makes to generate negative pressure, the second liquid being connected with liquid inlet port in liquid inlet port
Second liquid in container enters liquid outlet by the gap between liquid inlet port and needle-valve and needle seating, then by imbibition nozzle into
To the Outlet-side flow of jet mixer together with the first liquid in incident flow mixer, impinges upon and form concentration more on baffle
Uniform mixed solution.
When this first liquid stops entering, the negative pressure in vacuum noz(zle) and imbibition nozzle all disappears, and gas spring resets, will
Piston head jacks up upwards, and the outlet side of connecting hole and outlet nozzle disconnect, correspondingly, hydraulic spring grease cup also resets, needle-valve is pressed downward
It is set to block needle seating, second liquid stops entering in jet mixer.
When needing two or more liquid mixing, it is only necessary to which one group or more of suction is set on jet mixer accordingly
Liquid mouth and vacuum noz(zle), every group of imbibition nozzle and vacuum noz(zle) are correspondingly arranged one group of hydraulic control valve and pneumatic control valve can realize it is more
