　　Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. mainly produces foam tanks (pressure type proportional mixing device), fixed fire monitors, fire water monitors, fire turrets, low expansion foam generators, foam water dual-use monitors, foam hydrants, ground fire hydrants, ground quick opening pressure regulating fire hydrants, foam guns, mobile foam fire extinguishing devices, mobile fire monitors, remote control electric fire monitors, closed foam water sprinkler fire extinguishing devices, mobile foam tanks (semi fixed foam fire extinguishing devices), including foam fire extinguishing equipment, water fire extinguishing equipment, automatic fire extinguishing equipment, sprinkler cooling fire extinguishing system and fire fighting equipment accessories.

　　Ball valve is a widely used valve equipment, which is widely used in various fields such as petroleum, chemical, power, metallurgy, and steel. Ball valves are mainly used on pipelines to cut off, distribute, and change the direction of medium flow. The opening and closing component of a ball valve is a sphere, which rotates 90 degrees around the axis of the valve shaft to achieve the purpose of opening and closing. The sealing of existing ball valves is achieved by squeezing the valve seat with a ball, but the material hardness of the existing valve seat is high and the rebound is poor. In order to achieve valve sealing, it is necessary to increase the valve interference fit, which results in high valve torque, increases the overall cost of the valve, and leads to a relatively short service life of the valve.

　　Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. produces specialized ball valves for various fire monitors, with specifications and models of FQS80A, FQS80B, FQS80C, FQS65, and FQS80A/1.6. The fire monitor specialized ball valve is produced in accordance with the public safety industry standard GA79-94 "Performance Requirements and Experimental Methods for Fire Ball Valves" of the People's Republic of China, and is specifically designed for use with fire monitors. Its structural characteristics are: the connecting flange is a DN100 flange at the inlet and a DN80 flange at the outlet, with bidirectional sealing and a manual drain valve. When used in high-altitude areas in winter, the valve can be opened after being closed to drain the water inside the valve ball, thereby preventing the ball valve from freezing. Crack. The connection method can also be customized according to user requirements.

　　1. Anti freezing function: The stainless steel automatic drainage valve is installed below the frozen soil layer (the burial depth of the automatic drainage valve varies according to the depth of the frozen soil layer in the use area). When the gun seat is in the closed state, it can automatically discharge the remaining water in the chamber to prevent the above ground equipment from freezing. At the same time, it also saves the installation of gate valve wells and gate valves at the riser end of the fire pipeline, which not only saves investment, but also saves later maintenance costs and extends the service life of the water cannon;

　　2. Easy to operate: fast switch. Only use a wrench to rotate 4/5 turns to fully close and open;

　　3. Anti collision function: If the above ground part of this device is broken, the valve can automatically close and immediately stop water, without affecting the normal use of other equipment in the same pipeline. It can also repair damaged accessories under pressure;

　　4. Pressure regulation function: Turn the wrench to any position to achieve different outlet pressures, so that the water cannon spray point can reach the state. This product is a fire protection product for petrochemical enterprises.
