When the onset of fire, the fire control center should be able to manipulate the linkage damper is closed. 7 B elected by medium pressure pipe into the household, gas riser pipe should be laid in the well, in addition to the above requirements should fit, there should fit the following requirements:; 1) wells should use thicker seamless steel pipe and fittings 2) When the construction of a height greater than 100m high-rise construction of gas pipeline located in the well pipe, in addition to setting combustible gas alarm detector, you should also set a sense of urgency to intercept shock devices and equipment; and 3) seamless steel pipe gas wells should be used in the welding interface ; 4) ball valve, flange pieces, bolts, etc. should be selection pressure 1.0Mpa-tier system of goods. 4.3.1 When the gas riser straight through to the roof to clear deposited mainly located in the pipeline when demand wells, should fit the following requirements: On the interior walls by the external walls, pipe wells should set the size of a tube wells should be satisfied with the gas riser equipment, repair space requirements; after the manipulation signal, declaring sound an alarm or audible alarm. 2) Environmental noise greater than 60dB of acoustic spaces, sound the alarm noise sound pressure level should be higher than scenery 15dB. Types: 1) A Class; 2) Class B inspection equipment: Sound Level Meter 4.2 4.2.1 fire water system inspection requirements usually demand: all fire equipment components and equipment should fit the program selection, and should have the factory merchandise certificate, Fire merchandise should have fit the statutory documents of market access rules. Types: A Class 4.2.2 fire water inspection requirements: 1) the volume of fire water should be useful to fit the program requirements. 2) fire water replenishment equipment should be normal. 3) fire water and production, water day annexation of the pool, the water should be used to ensure that the fire does not make use of his skills and the normal way. 4) fire water level should be able to shine in the fire control room. Types: 1), 4) A Class; 2), 3) Class B inspection equipment: 0m ~ 50m steel tape 4.2.3 fire water tank inspection requirements: 1) the volume of fire water tank should fit the program requirements. 2) The primary channel width between the tank should not be less than 1.0m. 3) Check the channel width near the steel water tank should not be less than 0.7m. 4) The top of the tank to the bottom floor or beam at intervals of not less than 0.6m. 5) In addition to the series outside the fire water system, fire water tank outlet pipe should be located one-way valve, it should be tightly closed. 6) Fire water tank should pay approach. 7) When used in combination with other water tank fire water, fire water to ensure that does not make him the skills to be used in the normal way. 8) The tank should plan needs equipment inlet, outlet, overflow pipe, vent pipes. 9) Fire water tank level should be able to shine in the fire control room. Types: 1), 5), 6), 9) A class; 7), 8) Class B; 2), 3), 4) Class C inspection equipment: 0m ~ 5m steel tape, 0m ~ 50m steel tape 4.2. 4 regulator pump, booster pump and pressure tank 4.2.4.1 pressure water supply equipment inspection requirements: 1) conditioning water storage pressure tank, the job pressure should fit the program requirements. 2) The pressure tank pressure within the program should ensure that the scope of normal operations. 3) The pressure relief valve on the water supply equipment, pressure mortem inspection standards ", British Standards Institute BSI-PD6493" welding defects inspection standard number of approaches Raiders ", ASME Boiler and Pressure Vessel Code, Section XI Volume IWB3640 and 3650" austenitic and ferritic steel pipe defect inspection principles, "the British middle Electric Power R / H / R6" the integrity of the defective structure determination, "and so Chinese national" Ninth Five "scientific and technological projects," with industrial pressure pipeline safety assessment techniques and important The life of pressure vessels guess technical discussions "had opened the discussion in this regard, in order to develop the use of standards in line with China's national conditions suitable pressure pipe. Section 6 valve commodity classification and usefulness I. Overview: Valve is a fluid handling equipment line, which is on basic skills with a circulation piping or intercept medium, medium circulation changes, changes in the direction of media activities, scheduling media pressure and flow, protect the normal operation of the pipeline equipment. Many of the use of industrial valves Watt invented the steam engine in the future, the past three decades, as demand for oil, chemical, power plants, metallurgy, ships, nuclear, aerospace and other aspects of the valve, higher demand, we advance research and produce high parameters of the valves, the operating temperatures from cryogenic temperature -269 ℃ to 1200 ℃, and even up to 3430 ℃, job pressure from the ultra-vacuum 1.33x10-8MPa to EHV 1460MPa, valve size from 1mm to 600mm, and even the arrival 9750mm valves information developed from cast iron, carbon steel to titanium and titanium alloys, high-strength steel and other corrosion-resistant, driven development approach from manual valves to electric, pneumatic, hydraulic, programmable, digital, remote control and so on. Followed by the continuous development of modern industry, the demand for continually adding valves, a modern petrochemical equipment on demand tens of thousands of kinds of valves. The use of large valves open and close again, but generally because the manufacturing, use selection, improper repair, attack run, run, drip, leak appearance, thereby resulting in a fire, explosion, poisoning, scorch trouble, perhaps constitute the low quality of the goods quality, energy travels, equipment corrosion, material consumption travels, environmental pollution, and even constitute discontinued and other incidents have been endless, so we want to get high-quality valves, together also need to use, repair horizontal travel of the valve, which is engaged in valve operation personnel, repair personnel, and engineering and technical personnel, put forward new demands, in addition to carefully plan, a reasonable choice, other than the precise operation of the valve, but also in a timely manner to protect, repair the valve, the valve's "run, run, drip, leak we do various types of integrated business management consulting business management consulting organization Contact: Miss Hao Mobile: 13851787257 Telephone and Fax: 025-83619622 E-mail: 980837454@QQ.Com QQ: 1445404680 Company website: http: //www.sjzxnj.com/ Address: Qixia District and Yan Jinhua Road, Building 1602 Room 289
