Auxiliary tool for replacing valve

Abstract

The utility model relates to the technical field of pipeline maintenance, in particular to an auxiliary tool for replacing a valve. The outer side of the ingress pipe is hermetically sleeved with a sealing kit, the end of the sealing kit is provided with threads matched with the valve, a threaded connecting rod is installed in the ingress pipe, and one end of the threaded connecting rod is connected with a sealing expansion plug. The sealing kit is in sealed connection with the valve, then the threaded connecting rod is rotated to enable the sealing expansion plug to extend into the upstream gas pipeline to block the upstream gas pipeline, the valve can be replaced and maintained without closing a home-entry main valve, the influence on a user due to gas stop of the whole building is reduced, the maintenance time is shortened, and the maintenance efficiency is improved. The method does not need to give a day to inform a user of stopping gas for replacement, particularly avoids the situation that gas heating users are affected by gas stopping in winter, avoids the situation that pressure and diffusion are needed again due to gas stopping of the whole building, saves one day, shortens the construction period, saves the labor cost, improves the working efficiency, and saves the amount of gas needing to be diffused due to pressure of the whole building.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance. Background Art

[0002] When the gas pipeline is running, if the valve in front of the gas meter is leaking, the gas needs to be stopped for replacement and repair. The main valve entering the house needs to be closed, and the gas outage range and time of the gas outage should be informed in advance before repair. The disadvantage is that the valve maintenance and replacement time is too long, affecting the normal use of other residents. Utility Model Content

[0003] In order to solve the technical problem in the prior art that the main valve entering the house needs to be closed when replacing and repairing the valve of a gas meter, the utility model provides an auxiliary tool for valve replacement.

[0004] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0005] An auxiliary tool for valve replacement, wherein the outer side of an introduction tube 2 is sealedly sleeved with a sealing kit 3, the end of the sealing kit 3 is provided with a thread matching with a valve 6, a threaded connecting rod 7 is installed in the introduction tube 2, and one end of the threaded connecting rod 7 is connected to a sealing expansion plug 1.

[0006] The sealing kit 3 is sealed and sleeved on the outside of the introduction pipe 2 through a rubber gasket.

[0007] The other end of the threaded connecting rod 7 is swingably connected to the universal movable handle 4 through a support 8 .

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] By sealingly connecting the sealing kit to the valve and then rotating the threaded connecting rod to allow the sealing expansion plug to extend into the gas pipeline in front of the valve, thereby blocking the gas pipeline in front of the valve, the valve can be replaced and repaired without closing the main valve entering the house, thereby reducing the impact on users caused by gas outages in the entire building and reducing maintenance time. There is no need to notify users of gas outages and replacements one day in advance, especially in winter, to avoid the impact on gas heating users due to gas outages, and to avoid the need for re-pressurization and release due to gas outages in the entire building. This saves one day, shortens the construction period, saves labor costs, improves work efficiency, and saves the amount of gas that needs to be released due to pressure relief in the entire building.

[0018] The utility model provides an auxiliary tool for valve replacement, such as Figure 1 , 2 As shown in 7, the outer side of the introduction tube 2 is sealed with a sealing kit 3 through a rubber gasket, and the end of the sealing kit 3 is provided with a thread that cooperates with the valve 6. A threaded connecting rod 7 is installed in the introduction tube 2, one end of the threaded connecting rod 7 is connected to the sealing expansion plug 1, and the other end of the threaded connecting rod 7 is swingably connected to the universal movable handle 4 through a support 8. The angle of the universal movable handle 4 can be adjusted through the support 8, thereby facilitating the rotation of the threaded connecting rod 7 through the universal movable handle 4.

[0019] Working principle: Figure 3 As shown, the introduction pipe 2 is inserted into the valve 6, and the sealing kit 3 is connected to the valve 6 through the raw material tape. Figure 4 As described above, rotating the universal movable handle 4 causes the threaded connecting rod 7 to rotate, thereby pushing the sealing expansion plug into the gas pipeline 5 to block the gas pipeline 5. Figure 5 As shown, remove the seal kit 3, then Figure 6 As shown, disassemble valve 6, then Figure 7 As shown, install a new valve 6 and a sealing kit 3, rotate the threaded connecting rod 7 to withdraw the sealing expansion plug 1 from the gas pipeline 5, close the valve 6, and disassemble the auxiliary tools for replacing the valve.
