Abstract
Blocked inside a kind of heat exchanger maintenance closure protection device, mouth of pipe when being related to heat exchanger maintenance, overcome the problem of prior art.Its structure has：Support circle 1, packing 2, pressure ring 3, hex nut 4, square head bolt 5, blind flange 6, supported flange 8, soft rubber pad 9, mounting flange 10；Wherein circle 1 and mounting flange 10 is supported to be welded and fixed with heat exchanger mouth of pipe body；Remaining part can be dismantled or installed as needed.Blind flange 6, soft rubber pad 9 are installed when being blocked using the device, sealed by tightening inner side bolt presses soft rubber pad 9；Supported flange 8 is compressed pressure ring 3 by tightening outside bolt, then compress packing 2 and sealed.After maintenance terminates, increased 2 circle packing and blind flange 6, soft rubber pad 9, inner screw nut are removed.The utility model quickly and efficiently can carry out closure protection to Awaiting Overhaul heat exchanger, simple to operate, quick, have reference value to the such mouth of pipe closure of other solutions.
Description
Technical field
The utility model, which is related to inside heat exchanger, mouth of pipe when more particularly to heat exchanger is overhauled, to be blocked.
Background technology
Heat exchanger, which is connected common mode with other equipment, in general chemical plant installations has flange connect, be welded to connect, flange
Plus Ω packing rings etc., and will need to be changed during heat exchanger maintenance in order to prevent toxic and harmful gas or protect nitrogen etc. to enter heat exchanger to be checked
Hot device carries out insulation blocking.Use what flange connected can carry out heat exchanger inlet and outlet closure with blank off；And use be welded to connect,
It is the difficult point in maintenance process that flange, which adds the heat exchanging device of the non-dismountable mode such as Ω packing rings to import and export closure protection,.Such situation
The lower general scope of repair that expands is blocked, but this method uncertain factor is big, there is larger risk.Also can be using pipeline envelope
Gas shutoff capsule is blocked, but closure air bag is not good to gas plugging effect, and reliability is not enough.Therefore, one kind is invented quickly, just
Prompt, reliable heat exchanger inlet and outlet closure protection device tool is of great significance.
The content of the invention
Goal of the invention, to overcome prior art defect, it is proposed that effective heat exchanger maintenance closure protection device.
The utility model provides a kind of heat exchanger maintenance closure protection device, and its structure has：Support circle 1, packing 2, pressure
Ring 3, hex nut 4, square head bolt 5, blind flange 6 and its handle 7, supported flange 8, soft rubber pad 9, mounting flange 10；It is described
Support circle 1 be welded to connect with heat exchanger internal wall of pipe orifice body；1 opposite side of circle is supported to open single groove and carried out with mounting flange 10
Welding；Remaining part can be dismantled or installed as needed；Mounting flange 10 opens screwed hole, using hex nut 4, square toes
Bolt 5 is coordinated；Packing 2 is placed in the middle of support circle 1 and pressure ring 3；Blind flange 6 and its handle 7, soft rubber pad 9 seal for the mouth of pipe
Increase part during stifled state.
Application method：Blind flange 6, soft rubber pad 9 are installed, by tightening inner side bolt pressure when being blocked using the device
Tight soft rubber pad 9 is sealed；Supported flange 8 is compressed pressure ring 3 by tightening outside bolt, then compress packing 2 and sealed；
It need to increase by 2 circle packings during sealed condition to adjust the position of supported flange 8 and gap, this dress is completed by tightening inside and outside two circles bolt
Put sealing；After maintenance terminates, increased 2 circle packing and blind flange 6 and its handle 7, soft rubber pad 9, inner screw nut are removed, then
Directly tighten outer ring bolt to be fixed and clamped flange 8, retain the support circle 1 and mounting flange 10 being welded and fixed, so as to
Used during maintenance closure next time.
The beneficial effects of the utility model are quickly and efficiently can to carry out closure protection to Awaiting Overhaul heat exchanger, significantly
Improve the security of service work；The plugging device design of Sealing Structure is reasonable, with high reliability；The present apparatus makes
Used time is all connected by screw bolts, and installing/dismounting is easy, quick.
Brief description of the drawings

Specific embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model structure has：Support circle 1, packing 2, pressure ring 3, hex nut 4, square head bolt 5,
Blind flange 6 and its handle 7, supported flange 8, soft rubber pad 9, mounting flange 10；Described support circle 1 and heat exchanger internal wall of pipe orifice
Body is welded；1 opposite side of circle is supported to open single groove and welded with mounting flange 10；Mounting flange 10 opens screwed hole,
Coordinated using hex nut 4, square head bolt 5；Packing 2 is placed in the middle of support circle 1 and pressure ring 3, passes through the conducting pressure of pressure ring 3
Packing 2 is compressed to be sealed；Increase part when blind flange 6 and its handle 7, soft rubber pad 9 is mouth of pipe sealed conditions.
Fig. 1 show mouth of pipe sealed condition structural representation.
It is as follows using the plugging device program during maintenance：
The first step, as illustrated structure remove 2 circle hex nuts 4 successively, remove supported flange 8, pressure ring 3, packing 2, and
Decide whether to be changed according to the use state of packing.Second step, installs soft rubber pad 9, blind flange 8, and use hexagonal successively
Nut is tightened.3rd step, installs first lap pressure ring, packing, the second circle pressure ring, supported flange successively in order, and now packing is twined
Around 6 circles, the hex nut on the outside of supported flange is finally tightened, closure is completed.
After maintenance terminates, increased 2 circle packing and blind flange 6 and its handle 7, soft rubber pad 9, inner screw nut are removed, so
Outer ring bolt is directly tightened afterwards to be fixed and clamped flange 8, retains the support circle 1 and mounting flange 10 being welded and fixed, with
Just used during maintenance next time closure.
Mouth of pipe opening structure is as shown in Fig. 2 support circle 1 to be welded and fixed with adapter body, opposite side opens single groove
It is welded and fixed with mounting flange 10；Packing and pressure ring are installed, opening lower packing quantity is 4 circles；Finally install and compress
Flange 8, and be fixed by tightening hex nut 4.
The heat exchanger maintenance closure protection device of the utility model design is safe and reliable, effectively solves such situation
The problem of lower heat exchanger mouth of pipe closure.Meanwhile, this kind of structure operation is simple, quick, and the utility model is to other such pipes of solution
Mouth closure problem has highly important reference value.
