Description
Technical field
It the utility model is related to chemical industry leakage stopping technology, and in particular to a kind of pressure sealing for blind flange end face sand holes presss from both sides
Tool.
Background technology
In the enterprises such as the large-scale petrochemical, chemical industry, oil refining of consecutive production, the blind flange end face sand holes leakage of equipment pipe
Often occur, seriously jeopardize the continuous safety in production operation of device.In order to prevent to leak, and the normal production of device is not influenceed
Operation in the case of not parking, it is necessary to block leakage point.Most widely used method is exactly hook flange clamp in the prior art
Method, and then need to coordinate welding to carry out leak stopping for the higher leakage operating mode of many system pressures.But in actual use process
In, because most of leaking medium property is inflammable and explosive, it is impossible to coordinate welding, cause leak stopping failure or secondary leakage, system
Parking, huge economic loss is brought to producer, or even jeopardize the life security of leak stopping operating personnel 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, should
Method is suitable for that leakage system pressure is relatively low, the less operating mode 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, cause seal pressure inadequate, leak stopping failure.
To prevent to reveal, first have to solve is how to control fixture deformation to cause outside the sealant in sealing cavity
The problem of overflowing., can only be by increasing the thickness of fixture come Reducing distortion amount, with the increasing of thickness if not considering to change the structure of fixture
Add the abruptly increase for bringing clamp weight, the sealing for gently then destroying flange causes new leakage, heavy then device damage, threatens leak stopping operation
Personnel's personal safety.
The content of the invention
For deficiencies of the prior art, the utility model provides a kind of band for blind flange end face sand holes
Press blocking clamper, problem to be solved in the utility model is exactly, leakage system pressure is higher, medium for it is inflammable and explosive can not
During dynamic weldering, how to control fixture deformation, the sealant reduced in sealing cavity excessive, it is ensured that pressure sealing success.
The technical solution adopted in the utility model is as follows：A kind of Pressurized plugging clamp for blind flange end face sand holes, its
It is characterised by：Including pressing plate, jackscrew, teabowl with a cover；
The teabowl with a cover is arranged on below pressing plate, and the jackscrew is coordinated by external screw thread and pressing plate screw I to be screwed onto on pressing plate,
Turn clockwise jackscrew, stretches out the jackscrew rod end of pressing plate and the tight-lipped cooperation of teabowl with a cover injecting access opening, the screw on jackscrew jackscrew cap
II injecting passage, the teabowl with a cover injecting access opening passed sequentially through in jackscrew bar communicates with teabowl with a cover intracavitary.
The utility model has the following advantages that：The utility model solves existing blind flange end face sand holes pressure sealing construction
During, system pressure is higher, leakage rate is larger, medium is inflammable and explosive, integral coating（Hook flange）Fixture is yielding and nothing
Method coordinates the problem of welding, smoothly prevents the sealant in sealing cavity excessive, sealant is full of compacting in cavity,
Ensure certain seal pressure, reduce secondary leakage rate, improve the probalility of success of pressure sealing.
The utility model fixture is light and handy, sealing cavity is small, greatly reduces the dosage of sealant, reduces construction cost.
The utility model greatlys save the time of manufacture and construction, reduces environmental pollution, and this fixture is being pacified
It need not be welded during dress, greatly reduce the security risk in construction.
The utility model can realize the not parking on-line pressure sealant of chemical plant installations, avoid the parking of continuity chemical production device
Huge economic loss is brought to producer, or even jeopardizes the generation of the life security of leak stopping operating personnel sometimes.

Embodiment
As shown in Figure 1 to Figure 3, a kind of Pressurized plugging clamp for blind flange end face sand holes, including pressing plate 1, jackscrew 2,
Teabowl with a cover 3.
The one end of pressing plate 1 is rectangular slab, and the other end is circular slab, and a 1-1 of screw I is provided with the rectangular slab of pressing plate 1, is being pressed
The circular slab of plate 1 is provided with a through hole 1-2.
The jackscrew bar of the one end of jackscrew 2 carries external screw thread 2-1, and the jackscrew cap 2-2 of the other end of jackscrew 2 is rectangle or polygon,
The tapped 2-3 of screw II is provided with jackscrew cap 2-2 faces, in jackscrew bar be provided with injecting passage 2-4, the 2-3 of screw II and
Injecting passage 2-4 is communicated.
Teabowl with a cover 3 is circle, and injecting access opening 3-1, injecting access opening 3-1 and the chamber of teabowl with a cover 3 are provided with the center in the face of teabowl with a cover 3
Inside communicate.
As shown in Figures 4 to 6, the Pressurized plugging clamp application method for blind flange end face sand holes, step are as follows：
By the spiral-lock of teabowl with a cover 3 at the sand holes 6-1 of the end face of blind flange 6, the rectangular slab of the one end of pressing plate 1 is placed in the top of teabowl with a cover 3,
