Disclosure of Invention
The utility model discloses a novel negative pressure pipeline aims at solving the ground and takes out and take out pump station and take out inefficiency, and the energy consumption is on the high side, this difficult problem of equipment overload operation to and the connection of abnormal shape pipeline leads to sealed not tight problem.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
a novel negative pressure pipeline comprises a three-way pipe and a sealing sleeve, wherein the three-way pipe consists of a gas drilling sealing pipe and an extraction branch pipeline, the gas drilling sealing pipe is communicated with a perpendicular bisector of the extraction branch pipeline, internal threads are arranged at the end part of the gas drilling sealing pipe and at the two ends of the extraction branch pipeline, annular grooves are arranged on the end faces of the internal threads, the end part of the gas drilling sealing pipe and the two ends of the extraction branch pipeline are respectively connected with the extraction pipeline, an external thread is arranged at one end of the extraction pipeline, and an annular bulge is arranged at the tail end of the external thread; the gas drilling sealing pipe is characterized in that the sealing sleeve is of an annular structure, an annular gasket is arranged in the middle of the sealing sleeve, the extraction pipeline is in threaded connection with the internal thread of the gas drilling sealing pipe through the external thread of the extraction pipeline, the annular protrusion is connected with the annular groove in a jacking mode, the sealing sleeve is sleeved at the joint of the extraction pipeline and the gas drilling sealing pipe, and the annular gasket is located between the annular protrusion and the annular groove.
Preferably, the diameter of the middle part of the sealing sleeve is larger than the diameters of the two ends.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the utility model adopts the three-way pipe to solve the problems of poor sealing, negative pressure leakage, low extraction efficiency, high energy consumption of a ground pump station, overload operation of equipment and the like in the drilling and connecting process of the working face;
2. the utility model discloses a three-way pipe adopts threaded connection with taking out and taking out the pipeline, is that to connect more closely, and the junction has annular groove and annular protrusion further to seal in addition, overlaps the seal cover in the junction, and the middle part of seal cover is equipped with the annular packing ring, and the annular packing ring is located annular protrusion and annular groove, and when the seal cover is static, lean on after the precompression, the elasticity that the seal cover produced gives the sealing contact surface with certain pressure, forms first seal; when negative pressure is formed, the negative pressure is continuously increased by utilizing the change of the physical property of the sealing sleeve, and the sealing sleeve is more and more tightly sucked, so that the contact surface of the sealing sleeve is increased, an airflow leakage channel is blocked, and secondary sealing is formed;
3. the utility model discloses a guarantee leakproofness makes the middle part diameter of seal cover be greater than both ends diameter, avoids the negative pressure to last the rising to lead to the seal cover to break simultaneously.
