It is accurately controlled in zone of reasonableness set in advance, is to realize foam solution and the fire water important ring that high accuracy is mixed for a long time
Section, effectively solves froth fire extinguishing system not enough, the foam mixing liquid mixing that there is delayed, the foam solution trackability of foam solution supply
Required and the problems such as can not control in good time than that can not meet.Meanwhile, improve froth fire extinguishing system intellectuality, Digital Control water
Gentle fire extinguishing effectiveness.
The content of the invention
Its purpose of the invention is that a kind of metering self-balancing type froth fire extinguishing system control ball valve of offer, with structure
Simply, the characteristics of easily controllable, dependable performance, fast response time, high degree of regulation, the mixed-precision of foam mixing liquid is improved
With system fire extinguishing effectiveness, realization is automatically and manually adjusted.
Spheroid is provided with the technical scheme realized above-mentioned purpose and taken, including valve body, valve body, the spheroid upper end is through upper
Valve rod connects motor, and the spheroid lower end connects manual knob through lower valve rod, and the spheroid left side connects provided with outlet screw thread
Import nipple, import nipple one end are provided with the right side of head, outlet nipple one end connection outlet flange, the spheroid
Connect suction flange.
Beneficial effect
The present invention has advantages below compared with prior art.
1）Control ball valve of the present invention is installed on metering self-balancing type froth fire extinguishing system foam solution feeding pipe,
Device structure is simple, and sealing property is reliable, convenient to install and maintain, automatic, regulation manually can be achieved, with flow adjustment range
Extensively, foam solution droop loss is small, fast response time, driving moment and maintain the advantages of torque is small；
2）The ball valve body two ends are provided with feed liquor flange and go out liquid flange, and control ball valve internal foam liquid runner is located at ball valve sheet
In the end flanges of body two, import angle of throat is no more than 30o, and outlet widening angle is no more than 20o, and reduction foam flow quantity and pressure are damaged
Lose, and combine the throttle orifice inside ball valve body foam solution port of export nipple, be more uniformly distributed foam flow velocity.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the invention.

6, one end connection outlet flange 5 of nipple 6 is exported, the right side of spheroid 7 is provided with import nipple 11, import nipple
11 one end connect suction flange 12.
The lower end of valve body 4, which is located at manual knob 1, is provided with indicator of opening 2.
The both sides of spheroid 7 are provided with sealing ring 8, the difference connection outlet of sealing ring 8 nipple 6 and import screw thread of both sides
Joint 11.
Embodiment
Control ball valve of the present invention, its structure as shown in Figure 1, including manual knob 1, indicator of opening 2, lower valve
Bar 3, valve body 4, outlet(discharge) flange 5, outlet nipple 6, spheroid 7, sealing ring 8, upper valve rod 9, motor 10, import screw thread connect
First 11, the part such as suction flange 12.
Concrete structure and annexation are as follows：Spheroid 7 is by the sealing ring 8 of left and right two and import nipple 11, outlet spiral shell
Line joint 6 is loaded on the center of valve body 4, and spheroid 7 is connected through upper valve rod 9 with motor 10, and indicator of opening 2 is by 4 flutings
Pan head screw is fixedly mounted on the bottom of valve body 4, and spheroid 7 is connected through upper valve rod 3 with manual knob 1, suction flange 12, outlet(discharge) flange
5 are respectively and fixedly installed to the two ends of valve body 4 by bolt.
Lower valve rod 3 and the one end of upper valve rod 9 are processed into cubic boss, are connected respectively with motor 10 and manual knob 1,
To realize control, ball valve is automatic, manual regulatory function；The ground processing of the spherical outside surface of spheroid 7, improves surface accuracy, and enter in spheroid
Mouth side, outlet side install sealing ring 8 additional, at utmost reduce leakage quantity in foam solution.

Operation principle
When fire occurs for scene, metering self-balancing type froth fire extinguishing system starts, and fire water flow is in system worked well
Interior to have wave phenomenon, the mixing ratio of foam mixing liquid can not keep certain precision constantly.Therefore, in foam solution transfer pipeline
It is middle that control ball valve is installed, change foam flow quantity to adapt to the change of fire water flow by adjusting control ball valve aperture, realize
High accuracy is mixed foam flow quantity for a long time with fire water flow.The control ball valve has automatically and manually regulatory function；Automatically
During control, the motor of control ball valve receives the control instruction drive control ball valve inner ball rotation of field controller, treats
Field controller shows that the mixed proportion of foam flow quantity and fire water flow is recovered to preset value, and control ball valve stops turning
Dynamic, spheroid aperture is located at the working condition before motor stops；When the motor of control ball valve is in without electricity or failure shape
When under state, staff can field control ball valve bottom manual knob regulation spheroid aperture adapt to the change of fire water flow,
To meet the mixed-precision requirement of foam mixing liquid.
