Description
Technical Field
The utility model belongs to the flange protection casing field, and the utility model relates to a flange protection casing, specifically speaking are oil pipe says flange protection casing.
Background
The turbine lubricating oil system adopts L-TSA32 type turbine oil, the L-TSA32 flash point temperature is 186 ℃, and under the temperature, the mixture of grease steam and air can be flashed by adding small flame.
According to the combustion theory and experiments, the ignition point of the mixture of the atomized grease and air is obviously lower than that of liquid grease, and the mixture is extremely easy to deflagrate when meeting open fire or high temperature. The steam turbine oil system pipeline adopts flange connection in many places, because the oil pipe says and distributes extensively, can hardly avoid some oil pipe way flanges to be close to high temperature pipeline. Under extreme conditions, the sealing gasket at the flange sealing surface is broken and split oil, and because the lubricating oil pressure of the steam turbine reaches 2.1MPa, high-pressure lubricating oil is sprayed out in a mist form through the narrow sealing surface and is mixed with air to form oil mist, and the high-pressure lubricating oil is immediately deflagrated when encountering a high-temperature pipeline, so that great harm is brought to the safe operation of a unit.
Disclosure of Invention
In order to solve the problems, the utility model designs an oil pipe flange protective cover, which has stronger safety performance, can effectively prevent lubricating oil flange split oil from burning when meeting a high-temperature pipe, has wide application and can be suitable for oil pipe flange pieces with various sizes; the safety is good, and the safe and stable operation of a steam turbine oil system is ensured; the price is low, the popularization is strong, the manufacturing cost is low, and the requirement on the manufacturing process is low.
The technical scheme of the utility model is that:
an oil pipeline flange protective cover comprises a protective cover shell, wherein the protective cover shell is of a barrel-shaped structure with an opening at the lower end, is provided with a left part and a right part, can be conveniently and quickly buckled on a flange, the top of the shell is provided with a through hole, and the aperture of the through hole is matched with the outer diameter of an oil pipeline; one side of casing is equipped with the quick drainage device of grease, like stainless steel quick-operation joint, flange seal face after the oil, the grease gathering is collected in the protection casing, can drain the grease to the oil drum in fast through stainless steel quick-operation joint, prevents that the grease from leaking outward and arousing deflagration or pollute other equipment to high temperature pipeline.
Wherein the left and right parts of the shell are connected together through a fastener.
Furthermore, the left part and the right part are provided with fixing noses, the fixing noses are connected through a fastening piece, the fastening piece comprises a bolt, a flat washer and a nut, the bolt penetrates through the fixing noses and is in threaded connection with the nut, and the nut is provided with the flat washer.
In addition, the edges of the left and right protective cover shells are provided with tooth-shaped structures which are meshed with each other, so that the left and right protective cover shells are meshed together, and the structural stability and firmness of the product are improved.
By utilizing the principle that the ignition point of a mixture of atomized grease and air is obviously lower than that of liquid grease, the oil pipeline flange protective cover is adopted, the flange seal is strengthened by preventing the grease from being atomized, the grease is prevented from being scattered and sprayed when the flange seal surface is used for draining the grease, the grease is limited in the protective cover, the grease is introduced into an oil drum by drainage, and the flange draining the grease is prevented from catching fire.
The utility model has the advantages that: the safety performance is high, the lubricating oil flange split oil can be effectively prevented from being burnt in high-temperature pipelines, the application is wide, and the flange split oil can be suitable for oil pipeline flange pieces of various sizes; the safety is good, and the safe and stable operation of a steam turbine oil system is ensured; the price is low, the popularization is strong, the manufacturing cost is low, and the requirement on the manufacturing process is low.
The present invention will be further explained with reference to the drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in fig. 1, the oil pipeline flange protective cover comprises a protective cover shell 5, wherein the protective cover shell 1 is of a barrel-shaped structure with an opening at the lower end, is provided with a left part and a right part, and can be conveniently and quickly buckled on a flange, a through hole 5 is formed in the top of the shell 1, and the aperture of the through hole is matched with the outer diameter of an oil pipeline; one side of casing 1 is equipped with the quick drainage device of grease, like stainless steel quick-operation joint 2, flange seal face after the oil is split, the grease gathering is in the protection casing, can collect grease drainage to the oil drum fast through stainless steel quick-operation joint 2 in, prevents that the grease from leaking outward to high temperature pipeline and arousing deflagration or pollute other equipment.
The left and right parts of the shell 1 are connected together through a fastener. The left and right parts casing 1 is equipped with fixed nose 3, fixed nose 3 passes through fastener 4, fastener 4 includes bolt, plain washer and nut, the bolt pass fixed nose to with nut threaded connection, the nut is equipped with the plain washer.
In addition, the edges of the left and right protective cover shells are provided with tooth-shaped structures which are meshed with each other, so that the left and right protective cover shells are meshed together, and the structural stability and firmness of the product are improved.
By utilizing the principle that the ignition point of a mixture of atomized grease and air is obviously lower than that of liquid grease, the oil pipeline flange protective cover is adopted, the flange seal is strengthened by preventing the grease from being atomized, the grease is prevented from being scattered and sprayed when the flange seal surface is used for draining the grease, the grease is limited in the protective cover, the grease is introduced into an oil drum by drainage, and the flange draining the grease is prevented from catching fire.
