Description :

　　The SSFT series outdoor fire hydrants produced by Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. are mainly composed of valve sockets, lower valve body components, connecting pipes, fire hydrant shells (integrated with hydrants and cannons) and other components. Fire water cannons or fire water bags can be connected as needed to adapt to different situations. Users can adjust the water pressure and water volume using the built-in wrench of the product,; The opening method is to open the lifting shaft. During the opening process, the internal connecting rod moves vertically downwards, and the pressure of the internal fire water causes the internal pressure reducing device to open in sections. First, a part of the water flows upward through the pressure reducing device, and then another section is opened after a certain period of time to achieve the pressure regulating effect; When using this product, the internal device seals the automatic drainage device during movement. After use, the top rod of the originally sealed drainage device leaves, and the water left in the upper half after use is automatically discharged.

　　The SSFT series outdoor fire hydrants produced by Shandong Dongyue Crane and Fire Equipment Manufacturing Co., Ltd. have been improved on key parts based on ordinary hydrants, greatly enhancing their performance and applicability. This type of fire hydrant has stable and reliable performance, simple and flexible operation, easy maintenance, and can achieve rapid opening and pressure adjustment to meet the needs of various fire extinguishing places.

　　3. Install a standard rubber gasket on the installed pipeline flange and securely connect the fire hydrant and flange with bolts;

　　4. After the connection is made, a 1.6Mpa pressure sealing test is conducted, and the functions of rotation, opening, closing, and drainage are checked. After passing the inspection, the connection operation is carried out.

　　Use and maintenance

　　1. Regularly inspect the fire hydrant, check the opening size of the cover, remove dirt, check if the seal is intact, and repair any paint peeling.

After each use, a drainage valve should be used to drain the remaining water to prevent freezing and damage to the hydrant body. Especially in severe winter, attention should be paid to cold prevention, and the fire hydrant should be closed to prevent freezing and cracking of the hydrant body
