In the pipeline planning of ventilation and air conditioning systems, although it is calculated, if the working conditions of practical projects change, it is required to adjust the air volume of each part of the system through fire dampers and valves, carry out system debugging, fix the opening of the valves and distribute them reasonably to meet the planning requirements. As an essential fire fighting facility in engineering construction equipment, fire dampers can effectively prevent fire extension, in order to promote the safety environment plays a vital role, in order to reduce the production risk, to prevent security risks, today to introduce to us about the fire valve in the use of the process will have what common questions, for reference.
1. For the delivery of the fire control room, the return air pipe is not equipped with a fire damper at the place where it penetrates the wall. The purpose of setting up fire damper equipment is to ensure the fire safety of the fire control room. However, during the construction and review process, it will be found that some engineering planning drawings show the delivery of the fire control room, and the return air pipe is not equipped with a fire damper at the place where it penetrates the wall.

Fire damper.
2. The flash function of the fire control equipment is not perfect for the control of smoke prevention and smoke exhaust equipment. According to the rules in the specification: after the fire alarm is admitted, it is necessary to supply air to the air conditioner in the relevant parts, close the electric fire damper, and accept its response signal, launch the smoke prevention and smoke exhaust fan, smoke exhaust valve, etc. in the relevant parts together, and accept its response signal.
3. There is no pneumatic fire damper in the gas rescue system of the pipe network. GB requires: "During the delay period, the fire doors and windows shall be automatically closed, the ventilation and air conditioning systems shall be connected, and the fire damper equipment in relevant parts shall be closed." This requires that in the gas rescue system of the pipe network, it is necessary to have pneumatic fire dampers to be linked with fire control equipment.
4. There is no remote control when the air supply and smoke exhaust duct is used together. When some basements are built and the air supply and smoke exhaust duct is used in the parking lot, it is found that the stop valve in front of the blower and smoke exhaust can only be manually operated on site, and the fire damper cannot realize remote control of the control room. In case of fire, people need to go to the site to close the stop valve in front of the blower, which will directly affect the smoke exhaust system.
When the fire control valve is installed, it shall be installed according to the design requirements and calculated according to the drawings. There are 20 D = 160mrn steel butterfly valves and 10 D = 400mm steel butterfly valves. Please calculate the butterfly valve manufacturing, installation quantities and standard parts manufacturing. The calculation method of installation quantities is as follows:.
First, according to the title of the components marked on the construction drawing of the fire control valve, check the standard component weight table for the model, and find out the weight of each component.
Second, multiply the component of a component by the number of components in the construction drawing to find the total component of the component.
Third, divide the total weight of the fire control valve by 100 to obtain the manufacturing and installation quantities of the component, because the quota accounting unit is "100kg".
Four, the fire control fire damper valve parts manufacturing, device engineering quantity multiplied by the coefficient of 1.15, you get the parts brush oil engineering quantity.
Fire dampers are generally installed on the pipe of the mechanical smoke exhaust system, usually in an open condition, when the fire breaks out, open the smoke exhaust, when the smoke temperature in the smoke exhaust pipe reaches 280 degrees, it is closed, and it meets the requirements of smoke leakage and fire resistance integrity within a certain period of time, and has the effect of smoke isolation and fire prevention.
Finishing fire control valve should pay attention to what.
1. Regularly clean the outside of the regulating valve.
2. Regularly adjust the stuffing box and other sealing parts of the regulating valve, replace the sealing parts if necessary, and adhere to the tightness of the static and dynamic sealing points.
3. Regularly add smooth oil to the parts that need to be smooth.
4. Regularly discharge and clean the air source or hydraulic filter system.
5. Check the connection status and corrosion status of each connection point regularly, and replace the connection parts if necessary.
