SSFT150 quick opening pressure regulating anti-freeze and anti-collision fire hydrant manufacturer

Quick-opening, pressure-regulating, anti-freeze and anti-collision type outdoor above-ground fire hydrant
The series of quick-opening, pressure-regulating, anti-freeze and anti-collision outdoor fire hydrants are based on ordinary hydrants and have improved the key parts. It's more practical. The structure adopts a spring-closed drain port and achieves positive pressure sealing. It has:
,
switch quickly. Just one turn/turn of the wrench to fully close and open.
, voltage regulating function. Due to the pressure of the fire water, the internal pressure reducing device is opened in sections. First, a part of the water flows upward through the pressure reducing device, and then the other section is opened after being opened for a period of time, thus achieving the decompression effect.

Anti-freeze function. The stainless steel automatic drainage valve is installed below the frozen soil layer (according to the different depths of the frozen soil layer in the area of use, the burial depth of the automatic drainage valve also changes accordingly). When the fire hydrant is closed, it can automatically drain the remaining water in the cavity to prevent equipment from freezing. . At the same time, it also saves the installation of gate valve wells and gate valves in front of ordinary fire hydrant pipes, which not only saves investment but also saves later maintenance costs.
,
Anti-collision function. If this fire hydrant is broken, the valve can automatically close and stop the water immediately. It does not affect the normal use of other fire hydrants in the same pipeline. It can repair damaged accessories under pressure. It is the first choice product for municipal projects.
This product can be widely used in municipal governments, enterprises and institutions from all walks of life. It is especially suitable for various types of fire protection units at all levels such as petroleum, chemical industry, grain storage and wood processing, as well as textiles, ports, terminals, airports, storage areas, etc. It can also be safely used in cold northern regions. .The quick-connect fire hydrant involving the fire protection interface device is composed of a valve body, a valve disc, two interfaces, a spring, a sealing ring, etc. It is characterized in that there is a long cylindrical valve disc in the inner cavity of the valve body and the interface. The flap has a skirt, a valve and an elongated cylinder, and the elongated cylinder extends out of the end face of the interface. When a fire alarm occurs, the two internal buckle joints engage with each other, and the end surface of the hose joint pushes the elongated cylinder of the valve disc, causing the valve disc to slide axially. When the valve on the valve disc communicates with the port on the valve body, Connect the fire water source and put out the fire quickly.
