Equipment composition of indoor fire hydrants Indoor fire hydrants are composed of valve body, valve cover, valve stem, valve stem nut, valve disc, valve seat, hand wheel, fixed interface, umbrella hand wheel and other parts.
Indoor fire hydrants are the main facilities for fighting indoor fires in buildings. They are usually installed in fire hydrant boxes and used in conjunction with equipment such as fire hoses and water guns. They are one of the earliest and most common fire-fighting facilities in my country and are widely used in firefighting due to their reliable performance and low cost.
An indoor fire hydrant is an interface with a valve that supplies water to the fire scene from the indoor fire hydrant water supply network. It is connected to the indoor fire water supply pipeline and is a fixed fire-fighting facility in the building.
The components inside the indoor fire hydrant box include fire hoses, water guns, valves, and fire hydrant alarm buttons. Some fire hydrant boxes will be equipped with fire hose reels (portable fire hoses) and fire extinguishers.
Indoor fire hydrants are used to supply water to the fire scene through indoor pipe networks. They have valve interfaces and are fixed indoor fire-fighting facilities in factories, warehouses, high-rise buildings, public buildings and ships. They are usually installed in fire hydrant boxes and used in conjunction with fire hoses, water guns and other equipment. Pressure reducing and stabilizing fire hydrants are one of them.
CHFIRE Brand PSKD series electric fire water monitors are mainly composed of control systems (wireless remote control, wired long-distance electric control), electric monitor bodies, fire water supply systems, etc.
CHFIRE 200X pressure reducing valve is easy to maintain and has high pressure control accuracy. It is a functional valve that uses the medium's own energy to adjust and control pipeline pressure.
CHFIRE 200X Pressure reducing valves from China designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure.
CHFIRE 200X pressure reducing valve is easy to maintain and has high pressure control accuracy. It is a functional valve that uses the medium's own energy to adjust and control pipeline pressure.
CHFIRE 200X pressure reducing valve is a valve used to adjust the water supply direction in a water supply system where fire water and domestic water are connected in parallel.
CHFIRE 200X pressure reducing valve flange is an important component used in various industries such as oil and gas, chemical, and water treatment. It works by reducing the high pressure of the fluid flowing through the pipeline to a lower pressure level that is suitable for the downstream applications.
The pressure-reducing valve is adjusted to reduce the inlet pressure to a desired outlet pressure and rely on the energy of the medium itself to keep the outlet pressure automatically stable. From fluid mechanics point of view, pressure reducing valve is a throttling element, local resistance to change that by changing the throttling area, change the kinetic energy of the flow velocity and fluid, different pressure loss, so as to achieve the goal of decompression. Then the control and adjustment system can be adjusted to balance the pressure fluctuation of the valve and the spring force, so that the pressure of the valve remains constant within a certain margin of error. It is widely used in high rise buildings, water pressure of the city water supply pipe, and other occasions, so as to ensure the proper service water pressure and flow of water points in the water supply system.
CHFIRE 200X pressure reducing valve is a valve used to adjust the water supply direction in a water supply system where fire water and domestic water are connected in parallel.
The pressure reducing valve utilizes the pilot valve for self-control, does not require other devices and energy, is easy to maintain, has high pressure control accuracy, is less affected by inlet pressure and flow, and has reliable pressure reduction and stabilization.
The pressure reducing valve utilizes the pilot valve for self-control, does not require other devices and energy, is easy to maintain, has high pressure control accuracy, is less affected by inlet pressure and flow, and has reliable pressure reduction and stabilization.
200X pressure reducing and stabilizing valve consists of main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge to form hydraulic control takeover system. When in use, after the outlet pressure is adjusted, it can automatically maintain a stable outlet pressure.
200X pressure reducing valve is a valve used to adjust the water supply direction in a water supply system where fire water and domestic water are connected in parallel. When a fire occurs, the firefighting department urgently needs a large amount of water, and the domestic water supply is immediately cut off to ensure sufficient water for firefighting; when the firefighting stops using water and the pressure decreases, the valve automatically opens and is in a normally open state to restore the domestic water supply. This valve eliminates the need for a separate firefighting water supply network, greatly saving construction costs and water consumption. The valve has high control sensitivity, is safe and reliable, is easy to debug, and has a long service life.
Flanged globe type pressure relief valve (Fire pump relief valve) is used in the discharge of fire pump with flanged connection. It automatically relieves excessive pressure, so to maintain constant pressure. It allows the fire pump to be stopped without causing surging.
A Pressure Relief Valve is defined by NFPA 20 (3.3. 67.5 Relief Valve) as “A device that allows the diversion of liquid to limit excess pressure in a system.” In general, a PRV is a safety device, designed to protect a pressurized system during an overpressured event.
The pressure relief valve (500X) is a hydraulic control valve, mainly used in fire protection or other water supply systems to prevent system overpressure and maintain the pressure of the fire water supply system. When the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve will release the pressure in time to protect the safety of the pipeline.
A filter must be installed before the 500X pressure relief valve and the pressure holding valve. When adjusting, the screw on the pilot valve should be withdrawn, the water pump should be started to discharge from the pressure relief valve, and the adjusting screw should be gradually screwed in to gradually increase the pressure until the required set pressure is reached. Tighten the nut after adjustment.
500X pressure relief valve is a device used in water supply pipe network systems and urban water supply projects in high-rise buildings and living areas. The device consists of a main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control takeover system. It uses hydraulic automatic operation and can be used as a pressure relief valve or a pressure holding valve.
The 500X pressure relief/pressure holding valve consists of a main valve, a pressure relief/pressure holding pilot needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control takeover system. It can be used as a pressure relief valve or a pressure holding valve by hydraulic automatic operation. When used as a pressure relief valve, it can maintain the water supply line pressure below the set safety value; when used as a pressure holding valve, it can maintain the upstream water pressure of the main valve above the set value and maintain the upstream water supply pressure of the main valve.
500X pressure relief and pressure sustaining valve is mainly used to adjust the medium flow, pressure, temperature, liquid level and other process parameters in the field of industrial automation process control. According to the control signal in the automation system, the valve opening is automatically adjusted to achieve the adjustment of medium flow, pressure, temperature and liquid level.
