State strangling head one end close to each other to close, horizontal rack is respectively connected with the blind end of each strangling head, in the peace
It is also equipped with the two rooted tooth wheel shafts that are arranged side by side of left and right in tubulature, the rack of the gear shaft of the right and left respectively with the right and left is nibbled
Close, the upper end of each gear shaft stretches out installing pipe and is connected with drive device, corresponding under the driving of drive device
Gear shaft is rotated, and rack and strangling head are moved left and right in installing pipe, make corresponding strangling head that corresponding interface is beaten on or off
Close.
Using said structure, by opening interface at the two ends of installing pipe, and install and the one-to-one strangling head of interface, lead to
Over-driving device, gear shaft and rack control the movement of two strangling heads, so that the opening and closing of two interfaces are realized, it is actual
In use, fluid enters from one end of installing pipe, enter connecting tube through corresponding interface after the strangling head control flow at the end,
Then flowed out from the interface and strangling head of the installing pipe other end, so as to by the two-step evolution of two strangling heads, significantly increase
The throttling precision of device, and device is simple in construction, installs, safeguard and using being quite convenient to.
Pressure sensor is mounted in the left and right ends of the installing pipe, the pressure sensor is located at outside corresponding interface
Side；Pressure sensor is also installed at the middle part of the connecting tube.By setting these three pressure sensors to monitor feed liquor in real time
Locate, go out Fluid pressure at liquid and in connecting tube, the flow velocity and flow of fluid are judged by pressure differential, be easy to adjustment two in time
The position of strangling head, further improves throttling precision.
The drive device includes motor, worm screw and gear, and the worm screw lateral arrangement is connected with electricity in one end of worm screw
Machine, the gear is solidly set on the upper end of gear shaft, and gear and worm engaging, when motor is rotated, and the worm screw drives tooth
Wheel and gear shaft are rotated.Drive device is not only simple in structure, and intensity is high, accuracy is high.
Handwheel is connected with the other end of the worm screw.Handwheel is set to be easy to adjust section manually when motor is idle
Flow the position of head.
The rack that is connected on each strangling head is positioned opposite two, is provided with and rack in the inwall of the installing pipe
One-to-one neck, each rack is caught in corresponding neck.Two relative racks make the movement of strangling head more put down
Surely, the connection and between strangling head and rack is more consolidated.Rack is installed in the neck of installing pipe, it is to avoid rack is rocked,
Further be conducive to the even running of device, make the precision of device relatively reliable.
The limiter just to respective rack is respectively and fixedly provided with the one end of each neck away from strangling head.Limiter is set, when
Rack triggers limiter when running to inner terminal, is easy to disconnect motor in time, it is to avoid the damage of rack.
The left and right ends of the installing pipe are supported by vertical support.The supporting construction of installing pipe is simple, reliable.
The installing pipe is formed by the body docking of left and right two, the body, support, interface, gear shaft, rack and throttling
Head is symmetrically arranged along the positive middle part of installing pipe.Installing pipe is so divided into two bodys, makes the production of equipment, process more
Plus easily, and the monnolithic case of device is more attractive in appearance, and operation more facilitates.
Beneficial effect：The present invention is installed and the one-to-one strangling head of interface by opening interface at the two ends of installing pipe,
The movement of two strangling heads is controlled by drive device, gear shaft and rack, the opening and closing of two interfaces are realized, so as to carry
The throttling arrangements that a kind of precision is high, simple in construction, produce easy two-stage regulation and control are supplied.
