Fire truck with hand wheel heating temperature control outlet valve

Abstract

The invention relates to a hand wheel heating temperature control water discharge valve for a fire fighting trunk. The hand wheel heating temperature control water discharge valve for the fire fighting trunk comprises a hollow valve body. The valve body is provided with a valve clack, a connecting shaft, a shaft sleeve, a valve rod and a hand wheel in sequence from bottom to top. A spring is arranged in the shaft sleeve. The connecting shaft is fixedly connected with the spring. A water inlet and a water outlet are respectively formed in the bottom of the valve body. A U-shaped groove is formed in the valve body in the circumferential direction. Multiple electric heating tubes are arranged in the groove. A stainless steel spacer is embedded in the groove and then the groove is formed in a welded and sealed mode. A temperature measurement probe is arranged on the wall of the valve body and connected with a temperature controller, a power source and an electric heating strip in sequence. The hand wheel heating temperature control water discharge valve for the fire fighting trunk can be automatically adjusted and controlled according to real-time temperature inside the water discharge valve, so that heating is conducted, the inner portion of the water discharge valve is prevented from being frozen, and use is convenient and safe.

Description

technical field [0001] The invention relates to a water outlet valve, in particular to a handwheel heating temperature-controlled water outlet valve for a fire truck. Background technique [0002] With the rapid development of social economy, the harm and loss caused by fire to human life and property are increasing. Fire trucks are the main equipment for fire extinguishing, and the quality of the equipment directly affects the efficiency and success of fire extinguishing. The key components used in vehicles are directly related to the lives and safety of the people. The current water outlet valves used by fire trucks have the following defects: [0003] 1. At present, the known water outlet valve for fire trucks uses a ball valve. Since there is more or less residual water in the inner cavity of the ball valve, and the winter climate in northern my country is cold, it is easy to freeze in winter. If you need to use it, if you turn the valve hard It is easy to damage the se...

Problems solved by technology

[0003] 1. At present, the known water outlet valve for fire trucks uses a ball valve. Since there is more or less residual water in the inner cavity of the ball valve, and the winter climate in northern my country is cold, it is easy to freeze in winter. If you need to use it, if you turn the valve hard It is easy to damage the sealing ring, delay the timing of fire rescue, and cause heavy losses to the safety of people's lives and property.

[0004] 2. Because the firefighters are more urgent when they call the police, they open the valve faster, sometimes the hose connector cannot bear the pressure of the water outlet, causing the hose connector to fly out, causing damage to the life safety of the firefighters
