Abstract
The utility model discloses a kind of novel flange to leak blowout control device, specifically includes rubber parts and anchor ear；Wherein, anchor ear is that two semicircular rings form, and the both ends of circular rings are welded with the connecting plate of radial direction, there is the positioning hole for anchor ear positioning on connecting plate, and the centre of anchor ear is provided with the groove circularized, rubber parts is embedded in groove.The device is mainly used in the damage of wellhead sealing gasket ring, because borehole pressure is high, when the overflow in well is also prevented without suitable method for the moment, wellhead flange junction can be entered to rob in the case where not dismantling well head using the device and spray sealing.
Description
Technical field
It the utility model is related to field of petrochemical industrial, and in particular to a kind of novel flange leaks blowout control device.
Background technology
Petroleum gas adopt it is defeated during the distinctive high pressure of medium, multiphase, severe corrosive, easily cause oil well head flange
Gasket ring can deform, corrode after long-term use, in the course of time will seepage.Once leakage, the lighter causes production to give birth to
Environmental pollution living, accelerates the corrosion of peripheral equipment, equipment is terminated service life in advance；Severe one, which triggers, is poisoned, catches fire, exploding
Accidents Disasters.Therefore, flange leakage is administered and is classified as considerable safety environmental protection Control of Hidden by Petroleum Group.But usual well internal pressure
Power is higher, to flange leak stopping just into a problem.As described in patent CN204852771U, there is provided a kind of fixture, pass through two
Injecting mouth on individual half flange is toward jelly is injected in the groove on half flange, so as to form sealing.But in the mistake of injection jelly
Bubble in journey easily be present or be mixed on impurity, and flange and be provided with the reasons such as injecting mouth, seal use during exist compared with
The risk of high secondary leakage.
Utility model content
In order to solve the leakage problem at above-mentioned Petroleum Production scene, there is provided a kind of new gasket ring to be oozed outside flange
Leak into the device that spray is robbed in row sealing.The device is mainly used in the damage of wellhead sealing gasket ring, because borehole pressure is high, the overflow in well
, can be in the case where not dismantling well head to wellhead flange knot using the device when also being prevented for the moment without suitable method
Sealing is carried out at conjunction and robs spray, while is substituted using caulking gum part from this mode of injecting mouth injecting, service life and sealing
It is all more preferable.
The device is mainly made up of anchor ear, rubber parts, is formed wherein the anchor ear is two semicircular rings, and described two half
The both ends of circular rings are welded with the connecting plate of radial direction, there is the positioning hole for anchor ear positioning on the connecting plate, the anchor ear
Centre is provided with the groove circularized, and rubber parts is embedded in the groove.
In such scheme, the channel section of the rubber parts insertion is in prismoid shaped, and bottom size is wider.
In such scheme, the middle part of the rubber parts is provided with groove, the opening direction face upper flange of groove and
At the connection gap of lower flange, the opening size of groove is consistent with the size at connection gap.
In such scheme, the positioning hole is unilateral two, in upper and lower symmetry arrangement.
In such scheme, the anchor ear is tightened together by bolt and nut.
The beneficial effects of the utility model are：When the flange gasket of oil field is damaged, it is necessary to during emergency sealing,
The flange leakage blowout control device can be used, sealing can be carried out to wellhead flange junction in the case where not dismantling well head and robbed
Spray, while sealing is more safe and reliable relative to existing technology.

Embodiment
In order that the utility model is easy to understand, with reference to being specifically illustrating, the utility model is expanded on further.
As shown in Figures 1 to 4, a kind of novel flange leakage blowout control device, including rubber parts 6 and anchor ear 7, wherein, anchor ear 7
Formed for two semicircular rings, the both ends of two semicircular rings are welded with the connecting plate 8 of radial direction, had on connecting plate 8 for anchor ear 7
The positioning hole 5 of positioning, the centre of anchor ear 7 are provided with the groove circularized, rubber parts 6 are embedded in groove.
Further, the channel section that rubber parts 6 is embedded in is in prismoid shaped, and bottom size is wider.
Further, the middle part of rubber parts 6 is provided with groove, the opening direction face upper flange 1 and lower flange of groove
At 9 connection gap, the opening size of groove is consistent with the size at connection gap.
Further, positioning hole 5 is unilateral two, in upper and lower symmetry arrangement.
Further, anchor ear 7 is tightened together by bolt 10 and nut 11.
Concrete operations mode：
1st, installation prepares
The first step, rubber parts 6 is pressed in anchor ear 7, wherein the contact position of rubber parts 6 to stagger rigid body installation contact position
Put, this installation method can prevent that rubber overflows up and down in the gap of contact when anchor ear 7 from combining, and not reach the sealing effect of design
Fruit.
Second step, checks whether special cap nut 2 and sealing ring 3 all exist, and checks the quantity of bolt 10 of customization whether there is
Missing.
3rd step, clear up well head.
2nd, installation process
The first step, ready anchor ear 7 is embraced to the press-stored slot in the flange both sides of leakage, paid attention among rubber parts 6
Gap in alignment between the gasket ring 4 of lower flange 9.Anchor ear 7 or so has two symmetrical positioning holes 5 of Φ 30, ensure that two anchor ears 7
Do not misplace.
Second step, the connecting bolt 10 of anchor ear 7 are tightened up.If there is seepage in the gap of anchor ear 7, need to check rubber junction either with or without
Squeeze into relative groove.Continue to tighten up attachment bolt 10 after errorless.
3rd step, with our special bolt nuts one by one displace original well head bolt and nut.Will be by
Changed according to symmetrical mode.Due to being provided with sealing ring 3 on the special end face of cap nut 2, it is therefore desirable to method
The blue connecting hole periphery of bolt 10 is cleared up, and has been prevented hard thing to be clipped in below nut 11, has been influenceed to seal.
General principle of the present utility model, main features and advantages have been shown and described above.The technical staff of the industry
It is not restricted to the described embodiments it should be appreciated that this practicality is just new, the simply explanation described in above-described embodiment and specification
Principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various changes
Change and improve, these changes and improvements are both fallen within claimed the scope of the utility model.
