Abstract
The utility model relates to an area is pressed leaking stoppage screw and is annotated agent joint with plug switch. Include the joint body of fixing mutually with the flange, the upper end that connects the body is the injecting glue mouth, and the lower extreme that connects the body is for injecting the passageway, and injecting glue mouth and injection passageway communicate with each other, still include the plug, are equipped with the plug screw on the outer pipe wall of injection passageway, are equipped with the plug blind hole in the injection passageway corresponding to the plug screw on the pipe wall, and the plug is in the same place with plug screw spiro union, and the front end of plug loops through the plug screw, injects the passageway and gets into in the plug blind hole. The advantage is: the problem of current area press and to leak that the system pressure is higher, the spillage is great, can't close the injection passageway in the leaking stoppage work progress is solved, smooth prevention the sealant in the sealed cavity excessive, make the sealant be full of the compaction in the cavity, the sealed specific pressure of promising has reduced the secondary leakage rate, has improved the successful probability of pressing the leaking stoppage in the area, has avoided the parking trouble of continuity chemical production device.
Description
Technical field
The utility model relates to chemical industry leakage stopping technology, is specifically related to a kind of pressure sealing screw injecting joint with plug switch.
Background technique
In the enterprise such as large-scale petrochemical, chemical industry, oil refining of consecutive production, the leakage of the connection part such as flange, valve gland often occurs, and the continuous safety in production seriously jeopardizing device runs.In order to stop leakage, and don't affecting the normal production run of device, needing to block leakage point when not stopping.In prior art, most widely used way is exactly fixture leak stopping, and for a lot of Flange joint gap, less or valve gland profile is that oval leakage operating mode then needs to use steel band strapping or caulking method to carry out leak stopping.But, in actual use, due to sealing compound injected after cannot close injection canal, cause seal pressure lower, cause leak stopping failure or secondary leakage, system shutdown, bring huge economic loss to producer, even sometimes jeopardize the life safety of leak stopping operator.
As shown in Figure 4, traditional steel band strapping screw injecting joint connect design be by flange bolt by fastening for screw injecting joint, be suitable for the operating mode that leakage system pressure is lower, leakage rate is less.And when leakage system pressure is higher, leakage rate is larger, sealing compound injected after under higher leak pressure, the sealing compound in sealed cavity will there will be excessive situation, cause seal pressure inadequate, leak stopping failure.
Reveal to stop, what first will solve is exactly the excessive problem of the sealing compound how controlled in sealed cavity.The structure of screw injecting joint is changed if do not consider, introduction valve can only be installed additional on screw injecting joint and inject sealing compound in sealed cavity, injection canal is closed by the switch on introduction valve, be subject to the restriction of sealing compound mobility and the growth of injection canal, along with the rising of injection pressure, light then the seal element of injection tool (rifle, pump, pipe) damages, heavy then seal failure, threat leak stopping operator personal safety.
Summary of the invention
For prior art above shortcomings, the utility model provides a kind of pressure sealing screw injecting joint with plug switch, problem to be solved in the utility model be exactly, leakage rate higher at leakage system pressure larger time, the sealing compound how controlled in sealed cavity is excessive, guarantees pressure sealing success.
The technical solution adopted in the utility model is as follows: a kind of pressure sealing screw injecting joint with plug switch, comprise the joint body fixed with flange, the upper end of described joint body is gum-injecting port, the lower end of joint body is injection canal, gum-injecting port and injection canal communicate, it is characterized in that, also comprise plug, the outer tube wall of described injection canal is provided with plug screw, the injection canal inner tubal wall corresponding to plug screw is provided with plug blind hole, described plug and plug screw are screwed together, the front end of plug is successively by plug screw, injection canal enters in plug blind hole, injection canal is sectioned play and close injection canal effect.
The utility model tool has the following advantages: the utility model is by after the process of injecting glue terminates, the injection canal outer tube wall of original screw injecting joint increases a plug, close injection canal, solve leakage system pressure in existing pressure sealing work progress higher, leakage rate is larger, the problem of injection canal cannot be closed, prevent the sealing compound in sealed cavity excessive smoothly, sealing compound is made to be full of compacting in cavity, ensure certain seal pressure, reduce secondary leakage rate, improve the probalility of success of pressure sealing, avoid the trouble of shutdown of continuity chemical production device.The utility model can realize chemical plant installations not lay-by means of press seals.

Embodiment
As Fig. 1, 2, shown in 3, a kind of pressure sealing screw injecting joint with plug switch, comprise the joint body 2 fixed with flange 1, also comprise plug 3, the upper end of joint body 2 is gum-injecting port 2-1, the lower end of joint body 2 is injection canal 2-2, gum-injecting port 2-1 and injection canal 2-2 communicates, the outer tube wall of injection canal 2-2 is provided with plug screw 2-3, the injection canal 2-2 inner tubal wall corresponding to plug screw 2-3 is provided with plug blind hole 2-4, plug 3 is screwed together with plug screw 2-3, by screwing plug 3, the front end of plug 3 is successively by plug screw 2-3, injection canal 2-2 enters in plug blind hole 2-4, injection canal 2-2 is sectioned, achieve the effect of closing sealing compound injection canal 2-2, thoroughly solve seal pressure lower, the problem that secondary leakage rate is higher, avoid the parking accident of continuity chemical production device.
The outer tube wall of injection canal 2-2 is rectangle.
Plug screw 2-3 is identical with the aperture of plug blind hole 2-4, is all greater than the caliber of injection canal 2-2 pipe.
