The main factors affecting pressure delivery outlet price analysis along with the rapid development of ventilation equipment, pressure delivery outlet in various fields has also been an excellent use, such as staircases, corridors, on fire safety regulations, has a different device, to emergency fire protection equipment. Because the device has played such a crucial effect, pressure delivery outlet factory, also resulted in pressure delivery outlet offer very unstable, today it simple for us to analyze what elements of the device should offer. The original on pressure delivery outlet, the primary factors that influence its offer is still the product of the fire function. Speaking of which have to mention the positive pressure of the positive pressure of the fire door means two stairwell fire doors, the front room and the corridor between the differential pressure. The degree of positive pressure can be divided into a maximum allowable pressure value and the minimum pressure value. The maximum allowable pressure value refers to the maximum pressure values ??are all fire doors in the closed state fire doors at both ends to allow the general human can open the. The minimum pressure value refers lax fire personnel. Once the fire door open, the pressure to open the door before the stairway and lower chambers of the instantaneous, in order to avoid smoke intrusion, should adhere to the doorway of the blowback has a certain minimum wind speed should pressure difference. I hope the above description of the kind of equipment we have selected some help. The so-called positive pressure of the pressure delivery outlet pressure is what? Pressure delivery outlet generally used as delivery outlet, pressure delivery outlet role, but also directly with the fan coil supporting application, widely used in gathering complete air conditioning system, pressure delivery outlet types, and can also split multi-leaf valve , pressure delivery outlet, to adjust the air flow. By now, the most worrying question than the fire, the fire is built with the needs of modern, high-rise fireproof construction demand will be higher. Pressure delivery outlet fire function how? Whether domestic or foreign fire safety regulations, it has pressurized with demand, which should make in a fire, stairwell pressure> antechamber pressure> hallway or room pressure. The so-called positive pressure of the pressure delivery outlet, means the pressure difference across the fire door stairwell fire doors, the front room and the corridor between. The degree of positive pressure can be divided into a maximum allowable pressure value and the minimum pressure value. The so-called maximum allowable pressure value refers to the maximum pressure value all fire doors in the closed state of general human fire doors can be opened to allow the ends, on the maximum allowable pressure value, the value is not completely together countries, most countries 50Pa as are the maximum allowable pressure. The so-called minimum pressure value refers lax fire personnel. Once the fire door open, and open the door to the stairwell before the pressure chamber of the instantaneous drop, in order to avoid smoke intrusion, should adhere to the doorway at a certain wind speed should have minimal blowback pressure difference. Minimum differential pressure value (or minimum doorway wind speed) on fire and smoke requirements, countries have different rules and requirements.
