Problems solved by technology

[0002] As a new type of digital and intelligent automatic fire extinguishing equipment, the metered self-balancing foam fire extinguishing system improves the follow-up of foam liquid and the mixing ratio of the system through the control ball valve; while the existing control ball valve has a simple internal flow channel structure, which only realizes the pipeline medium The opening and closing function of the control ball valve is low, and it cannot be applied to the high-precision opening control requirements of the metering self-balancing foam fire extinguishing system.

Abstract

The invention discloses a control ball valve for a metering self-balancing type foam extinguishing system. The control ball valve comprises a valve body; a ball body is arranged in the valve body; the upper end of the ball body is connected to a driving motor through an upper valve rod; the lower end of the ball body is connected to a manual knob through a lower valve rod; an outlet threaded connector is arranged on the left side of the ball body; one end of the outlet threaded connector is connected to an outlet flange; an inlet threaded connector is arranged on the right side of the ball body; and one end of the inlet threaded connector is connected to an inlet flange. The control ball valve has the advantages that the structure is simple, control is easy, the performance is reliable, the response speed is high, the adjusting precision is high, the mixing precision of a foam mixture and the fire extinguishing efficiency of a system can be improved, and automatic and manual adjustment can be realized.

Description

technical field [0001] The invention relates to a control ball valve for a metering self-balancing foam fire extinguishing system. Background technique [0002] As a new type of digital and intelligent automatic fire extinguishing equipment, the metered self-balancing foam fire extinguishing system improves the follow-up of foam liquid and the mixing ratio of the system through the control ball valve; while the existing control ball valve has a simple internal flow channel structure, which only realizes the pipeline medium The opening and closing function of the valve has low control accuracy, and cannot be applied to the high-precision opening control requirements of the metering self-balancing foam fire extinguishing system for the control ball valve. [0003] The control ball valve used in the metering self-balancing foam fire extinguishing system in the firefighting field, as a key component of the system, automatically adjusts the opening of the ball according to the fl...
