Abstract
The utility model relates to a pressure seal sealant injection valve with a reversing valve. The pressure seal sealant injection valve comprises an injection valve, a clamp, a reversing valve body and a pipe plug, the clamp is provided with a flange, an external thread is arranged on a protruded channel of one end of the reversing valve body, a sealant injection port I with an internal thread is disposed on an inclined plane of the other end of the reversing valve body, a sealant injection port II with the internal thread is disposed on the body of one side of the reversing valve body, the sealant injection port I, the sealant injection port II and the protruded channel are respectively communicated with an injection channel located in the reversing valve body, the reversing valve body is in a screw joint with the clamp through the protruded channel, and the injection valve and the pipe plug can be in the screw joint with the sealant injection port I and the sealant injection port II respectively. The pressure seal sealant injection valve with the reversing valve has the advantages that the pressure seal can be achieved without stopping chemical equipment, the problem of a low success rate of pressure seal caused by the facts that an obstacle exists around the clamp and an injection gun can not be connected to inject sealants is solved, and the accident of stopping a continuous chemical industry production device is avoided.
Description
Technical field
The utility model relates to chemical industry leakage stopping technology field, particularly a kind of pressure sealing injecting valve that has reversal valve.
Background technology
In enterprises such as large-scale petrochemical that continuity is produced, chemical industry, oil refining, the leakage of pipeline, elbow, threeway, flange etc. often takes place, and seriously jeopardizes the continuous safety in production operation of device.In order to stop leakage, and don't influence the ordinary production operation of device, need under the situation of not stopping, block leakage point, most widely used way is exactly the anchor clamps leak stopping in the prior art.But, in actual use, because process units is arranged closely; The leakage position surrounding environment is complicated, and barrier is more, after anchor clamps are installed, can't connect filling gun injection sealant; Cause leak stopping failure, system shutdown brings gently then several ten thousand, hundreds of thousands unit economic loss; Heavy then up to a million, up to ten million economic losses, even the life security that jeopardizes the leak stopping operating personnel sometimes.Conventional brace is connected design with introduction valve as shown in Figure 1, and traditional introduction valve is connected design with anchor clamps be through screw thread introduction valve to be connected with clip vertical, is suitable for not having barrier and the bigger leak site of surrounding space near the anchor clamps.And when barrier such as other pipelines, body of wall is arranged around the leakage point, close together, filling gun can't be connected with introduction valve, can not in the anchor clamps cavity, inject sealant, causes seal pressure not enough, the leak stopping failure.If will stop leakage, what at first will solve is exactly how in the anchor clamps sealed cavity, to inject sealant.If do not consider to change filling gun closure, barrier can't be removed, and can only in sealed cavity, inject sealant through the introduction valve of both sides, through powerful injection pressure sealant is extruded into the centre position.Receive the mobile restriction of sealant, along with the part rising of injection pressure, excessive causing of anchor clamps local pressure is out of shape, and gently then sealant is run out of, the sealing failure, and heavy then anchor clamps burst apart, and threaten leak stopping operating personnel personal safety.
Summary of the invention
In view of the deficiency that prior art exists, the utility model problem to be solved is exactly when the on-disconnectable barrier that removes is arranged around anchor clamps, can sealant be expelled in the sealed cavity of anchor clamps, guarantees the pressure sealing success.
The utility model is for realizing above-mentioned purpose; The technical scheme that is adopted is: a kind of pressure sealing injecting valve that has reversal valve; Comprise introduction valve and the anchor clamps that flange is installed; It is characterized in that: also comprise switching-over valve body and plug, the protruding passage of said switching-over valve body one end is provided with external screw thread, and the inclined-plane of the said switching-over valve body other end is provided with the gum-injecting port I that has internal thread; One side of said switching-over valve body is provided with the gum-injecting port II that has internal thread, and said gum-injecting port I, gum-injecting port II, protruding passage communicate with the injection canal of switching-over in the valve body respectively; Said switching-over valve body is spirally connected through protruding passage and anchor clamps, and said introduction valve and plug can be spirally connected with gum-injecting port I and gum-injecting port II respectively.
The utlity model has following advantage: on original clamp structure, increase a reversal valve, can realize not lay-by means of press seals of chemical plant installations when being provided with barrier nearby at anchor clamps and introduction valve connecting portion.During concrete operations; Gum-injecting port through two different directions on the switching-over valve body links to each other with introduction valve; Change the closure of filling gun; Avoiding obstacles, thoroughly having solved anchor clamps has barrier can't connect the lower problem of pressure sealing success rate that filling gun injection sealant causes on every side, has avoided the parking accident of continuity chemical production device.

Fig. 2 is the utility model increases reversal valve between anchor clamps and introduction valve a structural representation.
Fig. 3 is the structural representation of the utility model reversal valve.
The specific embodiment
Like Fig. 2, shown in 3; A kind of pressure sealing injecting valve that has reversal valve; Comprise introduction valve 6 and the anchor clamps 4 that flange 5 is installed; Also comprise switching-over valve body 3 and plug 2, the protruding passage 3-1 of switching-over valve body 3 one ends is provided with external screw thread, and the inclined-plane of switching-over valve body 3 other ends is provided with the gum-injecting port I 3-2 that has internal thread; The body of switching-over valve body 3 one sides is provided with the gum-injecting port II 3-3 that has internal thread on one's body, and gum-injecting port I 3-2, gum-injecting port II 3-3, protruding passage 3-1 communicate with switching-over valve body 3 interior injection canals 7 respectively; Switching-over valve body 3 is spirally connected through protruding passage 3-1 and anchor clamps 4, and introduction valve 6 can be spirally connected with gum-injecting port I 3-2 and gum-injecting port II 3-3 respectively with plug 2.
During concrete operations, link to each other with introduction valve through the gum-injecting port of two different directions on the switching-over valve body, plug is connected on the gum-injecting port that does not connect introduction valve; In the anchor clamps sealed cavity, inject sealant smoothly; Make sealant in cavity, be full of compacting, guarantee certain seal pressure, reduced from the injection pressure of two side injection sealants; Improve the probalility of success of pressure sealing, avoided the trouble of shutdown of continuity chemical production device.Also but avoiding obstacles 1, and thoroughly having solved anchor clamps has barrier can't connect the lower problem of pressure sealing success rate that filling gun injection sealant causes on every side.
