Description
Technical field
The present invention relates to chemical industry leakage stopping technologies, and in particular to a kind of Pressurized plugging clamp for blind flange end face sand holes and
Application method.
Background technique
In the enterprises such as the large-scale petrochemical, chemical industry, oil refining of consecutive production, the blind flange end face sand holes of equipment pipe are leaked
Frequent occurrence, seriously jeopardize the continuous safety in production operation of device.In order to prevent to leak, and the normal production of device is not influenced
Operation, needs to block leakage point in the case where not parking.Most widely used method is exactly hook flange clamp in the prior art
Method, and leakage operating condition higher for many system pressures then needs that welding is cooperated to carry out leak stopping.But in actual use process
In, due to most of leaking medium property be it is inflammable and explosive, be not able to cooperate welding, cause leak stopping unsuccessfully or secondary leakage, system
Parking, brings huge economic loss to producer, or even jeopardize the life security of leak stopping operator sometimes.
As shown in fig. 7, traditional hook banjo clip general laws, is to wrap up flange as a whole by fixture to carry out injecting glue leak stopping, it should
Method is suitable for that leakage system pressure is lower, the lesser operating condition of leakage rate.And when leakage system pressure is higher, leakage rate is larger
When, after the completion of sealant injection under higher leak pressure, fixture interface stress deformation, the sealant in sealing cavity will
There is excessive situation, causes seal pressure inadequate, leak stopping failure.
To prevent to reveal, first have to solve is how that control fixture deformation causes outside the sealant in sealing cavity
The problem of overflowing.It, can only be by the thickness of increase fixture come Reducing distortion amount, with the increasing of thickness if not considering the structure of change fixture
Add the abruptly increase for bringing clamp weight, the sealing for gently then destroying flange causes new leakage, and heavy then equipment damage threatens leak stopping operation
Personnel's personal safety.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of for the with pressure stifled of blind flange end face sand holes
Leakage fixture and application method, problem to be solved by this invention be exactly, leakage system pressure is higher, medium be it is inflammable and explosive not
When active weldering, how to control fixture deformation, reduce sealing cavity in sealant it is excessive, it is ensured that pressure sealing success.
The technical solution adopted by the invention is as follows: a kind of Pressurized plugging clamp for blind flange end face sand holes, feature
It is: including pressing plate, jackscrew, teabowl with a cover；
The teabowl with a cover is arranged below pressing plate, and the jackscrew is screwed on pressing plate by external screw thread and the cooperation of pressing plate screw hole I,
Jackscrew is rotated clockwise, jackscrew rod end and the tight-lipped cooperation of teabowl with a cover injecting access opening of pressing plate, the screw hole on jackscrew jackscrew cap are stretched out
II passes sequentially through injecting channel in jackscrew bar, teabowl with a cover injecting access opening and teabowl with a cover is intracavitary communicates.
A kind of Pressurized plugging clamp application method for blind flange end face sand holes, it is characterised in that: steps are as follows, will cover
The rectangular slab of pressing plate one end is placed in above teabowl with a cover by bowl buckle at the sand holes of blind flange end face, and the screw hole I and teabowl with a cover of pressing plate are infused
Agent access opening is correspondingly arranged, and the through-hole on pressing plate other end circular slab is sleeved on the flange bonnet bolt for closing on sand holes side, is led to
Pressing plate is fixed on bolt by the cooperation for crossing nut and bolt, and jackscrew is screwed by the cooperation of external screw thread and pressing plate screw hole I
On pressing plate, jackscrew is rotated clockwise, stretches out jackscrew rod end and the tight-lipped cooperation of teabowl with a cover injecting access opening of pressing plate；
On-line pressure sealant injection valve and the screw hole II on jackscrew cap are screwed together, by injection gun and on-line pressure sealant injection valve
It is screwed together, injection gun injects sealant, and sealant passes sequentially through on-line pressure sealant injection valve, the screw hole II on jackscrew cap, top
It is intracavitary that injecting channel, teabowl with a cover injecting access opening in screw rod enter teabowl with a cover, and sealant will be filled, be compacted teabowl with a cover is intracavitary, and shape
It at certain seal pressure, turns off injection valve and removes injection gun, to achieve the purpose that leak stopping, realize chemical plant installations not
Stop on-line pressure sealant.
The present invention has the advantage that the present invention solves in existing blind flange end face sand holes pressure sealing work progress,
System pressure is higher, leakage rate is larger, medium is that inflammable and explosive, integral coating (hook flange) fixture is easily-deformable and can not cooperate weldering
The problem of connecing smoothly prevents the sealant in sealing cavity excessive, guarantees that sealant, full of compacting, certain in cavity
Seal pressure, reduce secondary leakage rate, improve the probalility of success of pressure sealing.
Present clip is light and handy, sealing cavity is small, greatly reduces the dosage of sealant, reduces construction cost.
The time of manufacture and construction is greatly saved in the present invention, reduces environmental pollution, and this fixture was being installed
It does not need to weld in journey, greatly reduces the security risk in construction.
The not parking on-line pressure sealant of chemical plant installations can be achieved in the present invention, avoids the parking of continuity chemical production device to factory
Family brings huge economic loss, or even jeopardizes the generation of the life security of leak stopping operator sometimes.
