Abstract
The utility model relates to a laterally removed corrugated plate flame arrester for a petroleum tank, belonging to fire safety equipment of the petroleum tank which is used for preventing the fire source outside the petroleum tank whisking into the petroleum tank to avoid the fire hazard happening. The laterally removed corrugated plate flame arrester for a petroleum tank is suitable to various petroleum products tanks. The laterally removed corrugated plate flame arrester for a petroleum tank adopts an aluminium alloy sawtooth-shaped corrugated plate, and a fire retardant core is loaded and fetched from the lateral surface of the case body, and is pressed from the lateral side of the case body, and moreover, a pressure measurement joint and a pressure measurement accessory are arranged. The laterally removed corrugated plate flame arrester for a petroleum tank is composed of a case body (1), a corrugated plate (13), a core case (14), a cylindrical pin (6), a spring (5), a side cover (9), etc. The laterally removed corrugated plate flame arrester for a petroleum tank has the advantages of simple structure, good air current performance, corrosion resistance, light weight, convenient check and maintenance, economy, practicability.
Description
The utility model---side take-out type corrugated plating flame arrester for petroleum tank belongs to Oil Tank fire safety equipment, is used to stop the exterior burning things which may cause a fire disaster of oil tank to scurry in the jar, avoids the oil tank presence of fire.This flame trap is applicable to various petroleum-type oil product storage tanks.
Corrugated plate dst flame trap before, housing are that two and half shells constitute, and fire-retardant core is set in the housing, on upper half-shell most cases all device breathing valve is arranged, when checking or clean fire-retardant core, the breathing valve of must dismantling earlier, open housing, could take out fire-retardant core, bring very big inconvenience to use.In addition because fire-retardant core is with specialized equipment corrugated plating to be entwined, take cleaning apart after, can't restore.Its crimped ribbon arrester system adopts corrosion-resistant steel oblique ripple mode, and it has a lot of defectives.Little as the corrosion-resistant steel coefficient of thermal conductivity, oblique ripple exists gas can not be single flow again, the invisible gas communication resistance that increased, and the fire-retardant core heat radiation is slowly.
Though there is the flame trap of being got fire-retardant core by the side dress in the past, fire-retardant core is to constitute with copper wire gauze, and housing upper half shell system down twists with screw, holds out against fire-retardant core, and fire-retardant core is with leaving big space between housing, and oad is big, seems heavy, inconvenient operation.
The utility model flame trap system adopts aluminum alloy zigzag wave card, fire-retardant core is got from housing side dress, lateral surface compressing, and be provided with measurement pressure interface and pressure measurement annex, its performance has also been eliminated every defective of original flame trap except that the every regulation that has satisfied standard GB 5905-86.Because back-fire relief is by corrugated plating, so claim the corrugated plate dst flame trap again.
The utility model flame trap structure mainly is made up of housing (1), corrugated plating (13), core shell (14), pin (6), spring (5) and side cover parts such as (9) as shown in Figure 1.The assembling of member system packs corrugated plating (13), stainless steel cloth (15) into and loads onto gland (12) behind the core shell (14), then loads onto column keyway (7) and pin (6).Side cover (9) is connected (opening of getting fire-retardant core is adorned in the side that is used for seal casinghousing) with bolt (2), packing ring (3), nut (4) with housing, be pressed on the spring (5), adds packing seal (8) simultaneously, makes all tightly sealings of fire-retardant core, housing and side cover.
Also be provided with the side pressure interface on this flame trap housing, use plug screw (10) that the pressure measurement interface is blocked at ordinary times, back out plug screw and bonded washer (11) during use, load onto pressure measuring tie-in (18), emulsion tube (16) and " U " type glass tube (17), as shown in Figure 2.The proper amount of clear water of packing in the glass tube can measure the difference of pressure of fire-retardant core both sides during by flame trap as gas, intuitively measures various data, checks out the fire-retardant core chocking-up degree at any time.
Corrugated plating line aluminium alloy serration ripple, gas becomes single flow by corrugated plating, change of direction not, circulating resistance is little, perfect heat-dissipating, and the thermal conductivity ratio corrosion-resistant steel is high more than 3 times, can directly purchase by factory, do not need any twister, only need on request a size to cut out to be placed in the core shell (14), pull down cleaning and do not have difficult recovery problem.
The both ends of the surface of fire-retardant core respectively are equipped with one deck stainless steel cloth (15), occur big slightly gap between corrugated plating to remedy.The wire net mesh is bigger, can not stopped up by greasy dirt.
Pin is a steel circular cylindrical, and an end has screw thread, passes column keyway and is screwed on the core shell, and the effect of column keyway is for spring provides a reference plane, and the main effect of pin is to be spring (5) location.Porose on the pin, be beneficial to that hook goes out fire-retardant core from housing.
This flame trap housing can bear 0.9Mpa hydraulic pressure, no leak, flawless, no permanent deformation.Qualified, respond well through carrying out explosion arrestment test and anti-burning test in 2 hours for continuous 13 times, do not have dissolving, do not have distortion, no tempering, performance.Be applicable to that flash-point is higher than-42 ℃ oil product storage.It can use with breathing valve in addition, also can use separately.Advantage is that the corrugated plating flame trap is simple in structure, and the gas communication performance is good, withstanding corrosion, and maintenance and inspection are convenient, and are economic and practical.
