Technical Field

[0001] The invention relates to the technical field of three-way pipe clamps, in particular to a stop three-way pipe clamp for pressure diversion. Background Art

[0002] The pressure tapping technology is suitable for the normal maintenance and renovation of various medium pipelines such as water, crude oil, refined oil, chemical media, natural gas, etc., and the emergency repair of emergencies. The main purpose is to transform the pipeline, add valves, replace pipe sections and other construction operations while the pipeline is operating normally and uninterrupted. In steel enterprises and daily life, there are many pressurized pipelines (gas pipelines, nitrogen pipelines, heating water pipelines) that need to be tapped under pressure for various reasons. Under the premise of not affecting the production of the enterprise and the stable operation of the pipeline network, the technology that can directly drill holes in the pipeline under pressure is particularly important. This can not only ensure the safe, stable and long-term operation of equipment and pipeline networks, but also reduce the economic losses caused by system shutdowns and emptying of materials in the pipeline network.

[0003] At present, when opening a hole under pressure in a PE pipeline, the conventional practice is to perform double sealing and double plugging at both ends of the pipe section to be constructed, use the hole sealing equipment to cut off the flow of the medium in the pipe section, and then use the temporary bypass installed on the hole sealing equipment at both ends of the pipe section to connect the two ends of the pipeline under construction, so that the medium in the pipeline can continue to be transported through the temporary bypass. However, this method is not only time-consuming and labor-intensive, but also there will be a certain period of interruption in the pipeline, which will affect life and production. For this reason, a stop three-way pipe clamp for pressurized diversion is proposed. Summary of the invention

After the hole opening is completed, the driving end of the hole opener is withdrawn to the top of the knife gate plate 8, but not completely removed. Then the knife gate plate 8 is tightened and the dust block 9 is reinstalled. Finally, the hole opener is removed. By using the stop three-way pipe clamp and the hole opener, pressurized hole opening can be performed under the premise of continuous flow, without affecting normal production and life, and at the same time saving time and labor. The structure of the combination of the three-way pipe clamp and the knife gate valve can effectively prevent leakage during the construction process of pressurized hole opening.

The groove 702 is worn, which affects the installation of the subsequent shunt positioning tube 12. By setting the guide threaded tube 18, before installing the hole opener, the limiting conical screws 19 can be screwed into the front and rear two guide threaded tubes 18 in sequence, and the tip of the limiting conical screw 19 is slightly nailed into the side wall of the tube 3 to be punched, so as to pre-position the upper half tube shell 1, prevent the upper half tube shell 1 and the lower half tube shell 2 from slipping and shifting due to vibration during the installation of the hole puncher and the subsequent punching process, which affects the accurate selection of the hole opening position. By setting the fastening steel hoop 20, the limiting conical screw 19 can be nailed into the tube 3 to be punched.
