Abstract
The utility model relates to a novel explosion-proof screen, which comprises a PVB board, and is characterized in that a layer of aluminum plate is wrapped at the periphery of the PVB board; the PVB board is fixed on a side plate of an oil tank via a fastening bolt a and a fastening bolt b; a silica gel sealing gasket is arranged between the PVB board and the side plate of the oil tank; an elastic sheet is further arranged between the fastening bolt a and the aluminum plate; an explosion-proof plate supporting gasket is further arranged between the fastening bolt b and the side plate of the oil tank; a connecting sheet is fixed on the surface of the PVB board via screws; a steel wire hanging rope is further connected between the connecting sheet and the fastening bolt a; and the fastening bolts a and b respectively consist of studs, nuts and gaskets. The novel explosion-proof screen has the advantages that once an accident occurs, the oil tank is protected from deformation, and part of elements connected with the oil tank are protected from being damaged; and even though suddenly escaping from the oil tank, the PVB board does not threaten people and equipment outside a safety range.
Description
Technical field
The utility model relates to a kind of new type explosion proof screen that can realize safety precautions.
Background technique
One of critical piece of lubricating oil module tank mounting in the combined cycle generation unit is steamed in combustion as GE; It mainly acts on is when the closed tank internal pressure is too high; Explosion-proof screen and fuel tank are separated, and discharge tank internal pressure, and fuel tank is indeformable does not damage with the part components and parts that are connected in fuel tank in protection.One of main effect that lubricating oil module tank mounting in the combined cycle generation unit is steamed in the GE combustion is exactly to be used for storing lubricant oil; Blower fan apparatus is housed on the tank mounting; Be used for filtering and discharging the mixed gas that contains a large amount of high-temperature oil gas of fuel tank, general fuel tank internal is a negative pressure.When breaking down, when the fuel tank internal high-temperature oil gas can not in time be discharged, along with the accumulation of time, tank internal pressure can raise; When tank internal pressure is too high, not only causes fuel tank local deformation easily, and produce destruction for the part components and parts that fuel tank connects; For this reason, at the explosion-proof screen of fuel tank sidewall top layout, when tank internal pressure is too high; Overcome the elastic force of spring sheet on the explosion-proof screen device, make explosion-proof screen break away from fuel tank, destroy the seal structure of fuel tank; Let high-temperature oil gas and atmosphere, discharge tank internal pressure, reach the effect of protection.
Yet that is that all right is ripe for the technology of explosion-proof screen in the existing technology, and therefore being badly in need of a kind of improved technology solves this problem.
Summary of the invention
The purpose of the utility model provides a kind of new type explosion proof screen that can realize safety precautions.
The technological scheme that the utility model adopts is:
The new type explosion proof screen comprises the PVB plate, and said PVB plate surrounding coats one deck aluminium sheet; Said PVB plate is fixed on the fuel tank side board through clamping bolt a and clamping bolt b; Be provided with the silica gel sealing pad between said PVB plate and the fuel tank side board, also be provided with spring sheet between said clamping bolt a and the aluminium sheet, also be provided with the bursting diaphragm Support cushion between said clamping bolt b and the fuel tank side board; Said PVB plate surface is fixed with connecting sheet through screw, also is connected with the steel wire lanyard between said connecting sheet and the clamping bolt a.
Said clamping bolt a and clamping bolt b form by stud, nut and pad.
The utility model has the advantages that: when causing danger, the protection tank mounting is modification not, and the part components and parts that are protected in the fuel tank connection do not damage; When PVB plate disengaging fuel tank flies out, can not produce destruction to people outside the safety margin and equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional view of the utility model A-A.
Wherein: 1, clamping bolt a, 2, spring sheet, 3, the PVB plate, 4, the silica gel sealing pad, 5, the bursting diaphragm Support cushion, 6, clamping bolt b, 7, connecting sheet, 8, the steel wire lanyard, 9, screw, 10, fuel tank side board, 11, aluminium sheet.
Embodiment
As illustrated in fig. 1 and 2, the new type explosion proof screen of the utility model comprises PVB plate 3; Said PVB plate 3 surroundings coat one deck aluminium sheet 11, and said PVB plate 3 is fixed on the fuel tank side board 10 through clamping bolt a1 and clamping bolt b6, is provided with silica gel sealing pad 4 between said PVB plate 3 and the fuel tank side board 10; Also be provided with spring sheet 2 between said clamping bolt a1 and the aluminium sheet 11, also be provided with bursting diaphragm Support cushion 5 between said clamping bolt b6 and the fuel tank side board 10, when causing danger; The protection tank mounting is modification not, and the part components and parts that are protected in the fuel tank connection do not damage, and said PVB plate 3 surfaces are fixed with connecting sheet 7 through screw 9; Also be connected with steel wire lanyard 8 between said connecting sheet 7 and the clamping bolt a1; When PVB plate 3 disengaging fuel tank side boards 10 fly out, guarantee that PVB plate 3 flies out apart from being no more than the tank mounting operational boundaries, can not produce destruction to people outside the safety margin and equipment; Play the purpose of safety in production, said clamping bolt a1 and clamping bolt b6 form by stud, nut and pad.
Claims (2)
