Abstract
It the utility model is related to a kind of liquid-injection equipment that can be dismantled online, including fluid injection nozzle (1), liquid injection pipe (2), fixation kit (3), cut-out gate valve (4), stuffing box (5), filler (6), gland (7), blind flange (8), leading screw (9).Wherein filler (6) forms dynamic sealing with gland (7), ensure that gas is not revealed in process pipe during liquid injection pipe (2) axial movement, blind flange (8) and stuffing box (5) composition static seal, are further ensured that sealing property.Liquid injection pipe (2) is driven to plug by leading screw (9) during this equipment disassembly and installation, closing gate valve blocks gas leak passage in process pipe after fluid injection nozzle (1) crosses gate valve (4) valve plate, the purpose for online dismounting fluid injection nozzle of not stopped work with realization device.
Description
【Technical field】
A kind of liquid-injection equipment that can be dismantled online is the utility model is related to, is noted suitable for oil refining, chemical field into gas
The occasion of liquid, the erosion corrosion that is particularly suitable for use in is serious, changes the installation of frequent, susceptible to plugging fluid injection nozzle.
【Background technology】
Oil plant generally notes a certain amount of liquid to reach the production requirements such as anti-corrosion, washing, scale inhibition, gas-liquid heat exchange
Enter among gas phase.Traditional oil-gas pipeline fluid injection generally by the way of straight tube filling, because the density of liquid is far above gas, is noted
The liquid entered enters oil-gas pipeline with column or raindrop shape, and the wind direction along oil gas gathers in duct bottom, trickled afterwards.Tradition
The utilization rate of fluid injection mode liquid is relatively low, and clean result is poor, and wastes serious.
Gas-liquid contact effect can be significantly improved by the way of nozzle is installed additional on liquid injection pipe, improves the utilization of each analog assistant
Rate.In the industrial practice of fluid injection nozzle, following technical barrier be present：
1. low discharge auxiliary agent often uses the less nozzle of spout, due to each analog assistant source of oil plant and complicated component,
Different auxiliary agent reactions generate various impurity in mixed, and misoperation, nozzle are easier to block in addition.
2. some nozzles are solidliquid mixture by medium, nozzle interior velocity of medium is higher, erosion corrosion it is serious, it is necessary to
Frequently change, be unfavorable for the long period health operation of device.
【Utility model content】
To overcome the shortcomings of in background technology, the utility model provides the liquid-injection equipment that can be dismantled online, can both save
About cost, the technological effect of fluid injection is improved, can be dismantled online in device production process again without stopping work, convenient maintenance and more
Change.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of liquid-injection equipment that can be dismantled online, including fluid injection nozzle (1), liquid injection pipe (2), mounting assembly (3), cut-out lock
Valve (4), stuffing box (5), filler (6), gland (7), blind flange (8), leading screw (9), it is characterised in that:Fluid injection nozzle (1) is inlayed
It on liquid injection pipe (2), can move axially, filler (6) and gland (7) composition dynamic sealing, blind flange (8) and fill out along liquid injection pipe (2)
Hopper (5) forms secondary static seal, and fixation kit (3) one end is connected with oil-gas pipeline, other end connection cut off gate valve (4) and
Dynamic and static sealing system, leading screw (9) are connected with blind flange (8), and the retaining of limits nozzle moving range is provided with leading screw (9)
Ring.
When nozzle needs dismounting, first the flange cover fastener of static seal is unscrewed, liquid injection pipe is extracted by leading screw, crossed
Gate valve is cut off after gate valve plate, progressively unscrews the securing member between stuffing box and gate valve afterwards, treat valve plate and stuffing box it
Between remain a small amount of gas leakage after pull down stuffing box, the maintenance to nozzle can be carried out and more changed jobs.Nozzle is again
During installation, nozzle is extracted to gate valve plate height by leading screw, stuffing box and gate valve are completed, afterwards by gate valve
Standard-sized sheet, process pipe is inserted the nozzle into by lead screw transmission.
By adopting the above-described technical solution, the utility model has the advantages that：
1st, nozzle can be repaired and change after line dismounting by being stopped work without device.
2nd, it is higher using secondary seal structure, safety coefficient.
3rd, have a wide range of application.
【Brief description of the drawings】
Fig. 1 is the cross-sectional view of equipment described in the utility model；
In figure：1st, fluid injection nozzle；2nd, liquid injection pipe；3rd, fixation kit；4th, gate valve is cut off；5th, stuffing box；6th, filler；7th, press

【Embodiment】
Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model are intended to protect
All technological improvements in the scope of the utility model.
A kind of liquid-injection equipment that can be dismantled online with reference to described in accompanying drawing 1, the one end of liquid injection pipe 2 connection fluid injection nozzle 1 are another
End is fixed on blind flange 8, and fixation kit 3 is made up of flange and sleeve pipe, is connected with process pipe, the connection of cut-out gate valve 4 one end
Fixation kit 3, other end bonding pad case 5, filler 6 produce radial tension by the axial compressive force of gland 7 and stung outside tight liquid injection pipe 2
Wall.Blind flange 8 coordinates with stuffing box 5 forms secondary static seal.
When a kind of liquid-injection equipment that can be dismantled online described in the utility model needs dismounting, first by the blind flange of static seal
8 fasteners are unscrewed, and are extracted liquid injection pipe by leading screw 9, are cut after crossing the valve plate of gate valve 4 (i.e. blind flange 8 reaches retaining ring position)
Disconnected gate valve, progressively unscrews the securing member between stuffing box 5 and gate valve 4, that treats to remain between valve plate and stuffing box lacks afterwards
Stuffing box is pulled down after amount gas leakage, the maintenance to nozzle can be carried out and more changed jobs.When nozzle is reinstalled, pass through
Leading screw 9 extracts liquid injection pipe 2 to gate valve plate height, and stuffing box 5 and gate valve 4 are completed, afterwards that gate valve 4 is complete
Open, process pipe is inserted the nozzle into by rotational lead screw 9.
The non-detailed portion of the utility model is prior art.
The embodiment selected herein to disclose purpose of utility model of the present utility model, is presently considered to be suitable
, however, it should be understood that, the utility model is intended to include all embodiments belonged in the range of this design and utility model
All changes and improvement.
