Detailed Description
The invention will be further described with reference to the accompanying drawings. It is to be understood that the above description is only for the purpose of better understanding of the present invention, and is not intended to limit the same.
Referring to fig. 1, a pressurized pipeline connection device is composed of a short-circuit pipeline 2, a valve 3, a temporary pipeline 4, a three-way joint 5, a sleeve 6, a sealing plate 7, a delivery pipe 8 and a hole opener (not shown).
One end of the short-circuit pipeline 2 is welded to the connecting position of the pipeline 1 with pressure with medium inside, the other end of the short-circuit pipeline is connected with one end of the valve 3 through a flange, and the other end of the valve 3 is connected with one end of the temporary pipeline 4 through a flange. Of course, a pipe with matching threads can also be used for the threaded connection with the valve 3. The valve 3 can be a ball valve (for example, model Q11F or Q41F) or a gate valve (for example, model Z41T). The other end of the temporary pipeline 4 is connected with a three-way joint 5, the three-way joint 5 can relieve the pressure generated by the medium of the pipeline with pressure in the hole opening process, and the phenomenon that debris enters the pipeline with pressure 1 during hole opening is reduced. One of them one end in the remaining both ends of three way connection 5 is connected eduction tube 8 for guide the medium that flows out to safe position, the other end then connect sleeve 6, the inside packing of sleeve 6 has sealing material, can be at the high-speed rotation of hole digger and flexible, effectively prevents the medium blowout when the trompil is not all formed. In order to achieve better sealing effect, the tail part of the sleeve 6 is also provided with a sealing plate 7. In order to enable the hole digger to successfully penetrate through the sealing plate 7, the sleeve 6, the three-way joint 5 and the short-circuit pipeline 2 in sequence to reach the connecting position with the pipeline under pressure, hole forming operation is carried out on the pipeline under pressure, and the inner diameters of the short-circuit pipeline 2, the valve 3, the temporary pipeline 4, the three-way joint 5 and the sleeve 6 are respectively larger than the diameter of a hole to be formed by the hole digger. The short-circuit pipeline 2 can also adopt a reducing pipeline, the inner diameter of the connecting end of the reducing pipeline and the pipeline with pressure 1 is larger than the diameter of the opening, preferably, the diameter of the connecting end is 2-3mm larger than the diameter of the opening, the inner diameter of the reducing pipeline is gradually enlarged from the connecting end to the other end, and correspondingly, the inner diameter of the valve 3 is matched with the inner diameter of the connecting end of the reducing pipeline. The hole digger can adopt a manual hole digger, and of course, an electric hole digger with proper power can be selected for saving labor.
The working process of the utility model is as follows:
firstly, one end of the short-circuit pipeline 2 is welded and fixed to a connecting position, and the size and the position of a recovery container used for containing and leading out a medium are determined according to specific conditions so as to avoid safety risks. Instead of providing a recovery container, only the delivery tube 8 can be provided without the need for a collection medium (e.g., non-flammable, non-toxic gases), the delivery tube can be held in a safe position with the nozzle not facing the person or material equipment. After the valve 3 is connected, pressure and leakage tests are carried out on the connecting position by adopting a medium and pressure experimental device which are the same as the medium in the pipeline with pressure, and the connecting quality of the pipeline is checked. And after the sealing performance of the joint is determined to be good and no leakage exists, the temporary pipeline 4, the three-way joint 5, the sleeve 6, the sealing plate 7 and the delivery pipe 8 are connected in place in the manner. The valve 3 is opened, the hole opener penetrates from the sealing plate 7, and holes are formed in the pipeline 1 with pressure after the hole opener reaches the joint. At the trompil in-process, gas or liquid medium can produce certain pressure, carry out the pressure release through three way connection 5, and the medium flows out from the air duct, and safe gaseous medium can directly be discharged from contact tube 8, and liquid then flows into in the container that has set up in advance through contact tube 8. A bowl-shaped protective cover (not shown) is also arranged at the tail of the hole cutter and the sealing plate 7, so as to prevent the hole cutter from being damaged due to the leakage of the sealing material in the sleeve 6. After the tapping is completed, the tapper is pulled out of the valve to close the valve 3, the parts 3-8 and the tapper are removed, and the pipeline 9 to be connected is connected to the valve 3 through a flange or threads, as shown in fig. 2.
When determining that the flow of one pipeline can not meet the requirement, two short-circuit pipelines 2 can be welded to shunt the medium. Firstly, welding a short-circuit pipeline at a connecting position according to the mode and finishing the hole opening, reserving the temporary pipeline, closing the valve, then welding a short-circuit pipeline at the other connecting position and finishing the hole opening, reserving the temporary pipeline, closing the valve, connecting the two temporary pipelines by using a three-way joint, and connecting the rest end of the three-way joint with a pipeline 9 to be connected, as shown in figure 3.
By adopting the device, the pipeline connection can be carried out under the condition of no stop of production, the medium leakage caused by overlarge pressure in the pipeline perforating process is avoided, and the construction safety is ensured.
The foregoing is only a partial embodiment of the present invention, and those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention. The scope of the invention is defined by the claims and their equivalents.
