Description

Gas medium pipeline flange leakage online processing device

technical field

The utility model relates to the technical field of leakage plugging devices, in particular to an online processing device for gas medium pipeline flange leakage.

Background technique

Gases such as gas and ammonia are the by-products and important energy sources of safe production in chemical companies and iron and steel companies. Long-term exposure to corrosive environments such as hydrogen sulfide gas and ammonia water, thermal expansion and contraction of pipelines caused by adverse weather such as sudden changes in temperature, dislocation caused by foundation settlement, and aging of flanges are all causes of leakage at the flange of the pipeline. Usually, the bolts at the joint of the pipeline are loose. , can be dealt with by replacing and tightening the bolts. If the flange gasket is damaged or the corrosion leaks beside the flange, the original treatment method is mainly to reduce pressure, including replacing the flange gasket or flange, and it is necessary to stop the machine and pump the blind plate for processing , hoop welding, low pressure can be directly processed, high pressure needs to be repaired and strengthened, and there is still a relatively large risk. Reduce production and maintenance costs, reduce downtime accidents, especially the non-spark performance, and ensure the safety of emergency repairs.

Utility model content

The purpose of this utility model is to provide an on-line processing device for flange leakage of gas medium pipelines. The device has a simple structure and is easy to use. Influence, the fixture and the pipeline are installed in non-hard contact, and the sealing effect is good; the exhaust hole and the exhaust valve are set to remove the air pressure in the fixture in time to improve work efficiency.

In order to overcome the above technical problems, the technical solution adopted by the utility model is: an on-line processing device for gas medium pipeline flange leakage, including a clamp body and an ear plate, and the clamp body is provided with an injection port and an exhaust hole. An injection valve is connected to the injection port, an exhaust valve is connected to the exhaust hole, a groove is arranged in the main body of the clamp, and a sealing strip is arranged on the edge of the groove, and the other part of the sealing strip is One side is attached to the gas medium pipeline, and a sealing gasket is arranged on the ear plate.

Further, the injection port and the exhaust hole are respectively symmetrically arranged on the two fixture main bodies.

Further, bolt holes are opened on the lug plate, and the fixture main body is connected by bolts and nuts arranged on the lug plate.

Further, preferably, the glue injection valve is connected to a glue injection pump, and the quick-setting agent is injected into the flange leak through the glue injection pump.

Further, the sealing strip and the gasket are made of rubber.

The beneficial effects of the utility model are:

1. To shorten the maintenance time and make full use of the production time, the online replacement of the gas medium pipeline can be realized, which greatly shortens the maintenance time.

2. Reduce maintenance cost, facilitate maintenance, and improve equipment utilization rate. The structure design is simple and stable, which is convenient for maintenance personnel to operate, greatly reduces the consumption of manpower and material resources in the maintenance process, improves operating efficiency, and has high safety. From the overall consideration, the utilization rate and value of production equipment are greatly improved.

3. High safety. The utility model solves the risk of ignition and explosion of gaseous media such as gas and ammonia. It is simple and fast to install, saves time and effort, and has high safety performance.

4. A sealing strip is set between the main body of the fixture and the pipe, and sealing gaskets are set on the lug plates, which makes the device have a better sealing effect, prevents the sealant from leaking during the injection process, and effectively improves the sealing of the leakage point. Blocking effect, set the exhaust hole and exhaust valve, can remove the air pressure in the fixture in time.
