Anti freezing pressure regulating fire water cannon ball valve, national standard dual interface manual drain valve, straight through fire cannon ball valve

Description :

　　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.

　　Pressure resistance and sealing performance

　　1. Voltage resistance performance

　　The fire ball valve should undergo a pressure resistance test according to the provisions of 6.4.2, and should be able to withstand a static water pressure of 4 times the rated working pressure for 5 minutes. There should be no visible leakage at the connection between the pressure bearing wall and the valve body and valve cover during the experiment, and there should be no structural damage to the shell (including the packing box and the connection between the valve body and valve cover).

　　Leakage at the packing is allowed under the pressure of the pressure test, but there should be no visible leakage when the test pressure drops to the sealing test pressure.

　　2 Sealing performance

　　When conducting a sealing performance test on ball valves according to the provisions of 6.4.3, they should be able to withstand a hydrostatic pressure of twice the rated working pressure and maintain it for 5 minutes. The ball valve should have no visible leakage during the experiment.

　　Static pressure life

　　Ball valves should undergo static pressure life testing according to the provisions of 6.5, and their static pressure life should not be less than 10000 times.

　　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.

　　The FQS80 fire water cannon ball valve produced by the company has the following advantages:

　　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.
