Description
Technical field
The utility model relates to the anti-coking safety cover used in petroleum and chemical industry field.
Background technique
In petroleum and chemical industry field, in order to overhaul with the needs of construction and installation often on some pressurized containers and provision for sealing as: stretch component in heavy oil catalytically cracking equipment, coking plant, coal chemical engineering equipment etc. are plugged with.Because the reaction medium in the inner chamber of these pressurized containers and provision for sealing mostly is high-temperature gas, and in gas, be mixed with multiple solid-state and liquid impurity.In use, impurity is stretched in the gap between component outer wall and sleeve pipe in being deposited on, and in the course of time, forms coking and stretches component and sleeve pipe adhesion by interior.This coking is very hard, needs dismounting in stretch component carry out checking maintenance time, be difficult to stretch component removal by interior.
In order to stretch the problem of component and sleeve pipe coking adhesion in solving, at present, as shown in Figure 1, operator fills high temperature resistant nonmetallic material 3 interior stretching in structural member 1 and the gap of sleeve pipe 2, can reduce the formation of coking to a certain extent.But when equipment running at full capacity, the fluidised form of the reaction medium in inner chamber 5 reaches peak-peak, at this moment medium flow field complicated and changeable is easy to the high temperature nonmetallic material of filling to empty, thus expose gap, in container under pressure effect, be enough to high-temperature liquid state Jiao is infiltrated, thus produce coking.
Model utility content
For exist in prior art in interior problem of stretching easy coking adhesion between component and sleeve pipe; the purpose of this utility model is to provide a kind of Novel anti-coking safety cover; this anti-coking safety cover is nested with to be stretched on component interior; stretch the gap of component outer wall and internal surface of sleeve pipe in having filled up, thus reach the object of anti-coking.
To achieve these goals, disclosed in the utility model, technological scheme is as follows:
Novel anti-coking safety cover, stretch on component in this anti-coking safety cover is set on, stretch component in described when being plugged in sleeve pipe, interior gap of stretching between component outer wall and described internal surface of sleeve pipe is filled up by anti-coking safety cover, in anti-coking safety cover is close, stretches component insertion end place is provided with self-locking ring and self expandable ring, described self-locking ring and described self expandable ring hoop are stretched on component interior, self-locking ring stretches component outer wall in being tightly combined in by himself deformation is closely connected, anti-coking safety cover and interior component of stretching is sealed; Self expandable ring fits tightly at internal surface of sleeve pipe by himself deformation, by anti-coking safety cover and bobbin seal.
Further, described self-locking ring is worked out by resistant to elevated temperatures wire gaze, its expansion coefficient be less than described in stretch the expansion coefficient of component, rely in after being heated the expansion of stretching component and self-locking ring to fit tightly.
Further, self expandable ring described in described self-locking chain rate stretches the insertion end of component in described.
Further, described self expandable ring is compressed by high fine and close deoxidation ceramic fiber and forms.
Further, described anti-coking safety cover is made up of resistant to elevated temperatures nonmetallic material.
Further, described anti-coking safety cover is composited by expanded deoxidation ceramic fiber, corundum and high temperature silicon wafer glue.
Further, described anti-coking safety cover, described self-locking ring and described self expandable ring are made into integration.
The advantage of the utility model anti-coking safety cover is, utilizes anti-coking safety cover to be crammed in interior gap of stretching between component and sleeve pipe, avoids impurity to retain and directly form coking; Respectively safety cover and internal surface of sleeve pipe, safety cover and interior component outer wall of stretching are sealed by self expandable ring and self-locking ring, avoid tar to infiltrate.
Accompanying drawing explanation
Fig. 1 be in prior art in stretch the connection diagram of component and sleeve pipe;
Fig. 2 is the schematic diagram of the utility model anti-coking safety cover.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 2; for the specific embodiment of Novel anti-coking safety cover; high-temperature gas is filled with in the pressurized container used in petroleum and chemical industry field and provision for sealing inner chamber 5; in being plugged with in inner chamber 5, component 1 is stretched by pressurized container and provision for sealing; the wall 4 of pressurized container and provision for sealing is provided with and the interior sleeve pipe 2 stretched component 1 and match; inside stretching component 1 is plugged in sleeve pipe 2, stretches on component 1 in the anti-coking safety cover 6 in the utility model is set on.Interior gap of stretching between component 1 outer wall and sleeve pipe 2 inwall is filled up by anti-coking safety cover 6, and anti-coking safety cover 6 is made up of resistant to elevated temperatures nonmetallic material, is specifically composited by expanded deoxidation ceramic fiber, corundum and high temperature silicon wafer glue.In anti-coking safety cover 6 is close, stretches component 1 insertion end place is provided with self-locking ring 7 and self expandable ring 8, the insertion end of component 1 is stretched in self-locking ring 7 is more close than self expandable ring 8, self-locking ring 7 and self expandable ring 8 hoop are stretched on component 1 interior, self-locking ring 7 stretches component 1 outer wall in being tightly combined in by himself deformation is closely connected, anti-coking safety cover 6 and interior component 1 of stretching are sealed, specifically, self-locking ring 7 is worked out by resistant to elevated temperatures wire gaze, the expansion coefficient of component 1 is stretched in its expansion coefficient is less than, when pressurized container and provision for sealing work, component 1 is stretched and from shrink ring 7 in the high temperature of inner chamber 5 is passed to, inside stretch component 1 expanded by heating and self-locking ring 7 fits tightly, realize sealing.Self expandable ring 8 fits tightly at sleeve pipe 2 inwall by himself deformation, anti-coking safety cover 6 and sleeve pipe 2 are sealed, specifically, self expandable ring 8 is compressed by high fine and close deoxidation ceramic fiber works out, its compression ratio reaches 25%, and the external diameter of tensioner ring 8 and sleeve pipe 2 internal diameter size closely cooperate, when pressurized container and provision for sealing work, the high temperature tar of inner chamber 5 infiltrates to cooling solidification in the pole small spaces of the deoxidation ceramic fiber of tensioner ring 8, and make tensioner ring 8 start to expand by piling up gradually, and with sleeve pipe 2 crush seal, final realization is to the thorough sealing of high-temperature oil gas Jiao.In order to improve the sealing of anti-coking safety cover 6, preferably anti-coking safety cover 6, self-locking ring 7 and self expandable ring 8 are made into integration.
Above-mentioned example is just for illustration of the utility model, and mode of execution of the present utility model is not limited to these examples, and what those skilled in the art made meets the various embodiments of the utility model thought all within protection domain of the present utility model.
