The investment is small, the cost is low, the practicability is realized, and the construction efficiency is improved.
Description
Technical Field
The utility model relates to a water conservancy valve field, bypass valve intake steel rubber stopper is stifled promptly.
Background
In the prior art, a water filling device is arranged in a water diversion tunnel between a middle hole high-pressure arc-shaped working gate and a middle hole flat plate overhaul gate of a water conservancy dam, and a bypass valve is used for opening the middle hole flat plate gate to perform the functions of filling water and leveling pressure. A plurality of bypass valves are arranged in the corridor, each group of bypass valves is provided with two water intake ports, and the water intake ports are deep underwater for dozens of meters. The pipelines and the valves are operated for 10 years, the pipelines are seriously rusted due to the moist environment, the pipelines are not cleaned for many years, the valves are also silted up, and the by-pass valve is overhauled in order to eliminate hidden dangers of equipment, improve the health level of the equipment and ensure the use safety and reliability of the by-pass valve. The prior plug made of wood is not good in effect when placed into a water inlet of a bypass valve, a diver needs to dive for multiple times to observe plugging and swell when encountering water, and the plug is difficult to dismount due to the fact that the plug is laborious in dismounting. The storage is inconvenient, the crack is easy to cause, and the secondary use is impossible.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the aforesaid not enough and provide a bypass valve intake steel rubber stopper that is rational in infrastructure, long service life.
The technical solution of the utility model is that: the steel rubber plug for the bypass valve water intake is characterized by comprising a section of pipe body, wherein a front end circular plug plate which is larger than the diameter of the pipe body is welded at the front end of the pipe body, a rear end circular plug plate which is larger than the front end circular plug plate is welded at the rear end of the pipe body, rubber is wrapped in the outer circle surface between the front end circular plug plate and the rear end circular plug plate and forms a conical round table shape, a screw rod is connected between the front end circular plug plate and the rear end circular plug plate in a penetrating mode along the center, a locking nut is screwed on the screw rod on the outer surface of the front end circular plug plate and the rear end circular plug plate, and the tail end of a screw rod head of the rear end circular plug plate is exposed and provided with a pull ring.
The utility model has the advantages that: 1. the rubber is adopted to wrap the steel pipe structure, so that the corrosion is low, the weight is light, and the strength meets the working requirement. Is not easy to damage when being dismantled and can be continuously used. 2. Flexible operation, simple and reasonable structure, safety and reliability. 3. The investment is small, the cost is low, the practicability is realized, and the construction efficiency is improved.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
Referring to fig. 1, the part names are as follows: the pipe comprises a pipe body 1, a front end circular blocking plate 2, a rear end circular blocking plate 3, rubber 4, a screw rod 5, a screw cap 6 and a pull ring 7.
Referring to fig. 1, the steel rubber plug for the bypass valve water intake is characterized by comprising a section of pipe body 1, a front end circular plug plate 2 larger than the diameter of the pipe body is welded at the front end of the pipe body 1, a rear end circular plug plate 3 larger than the front end circular plug plate 2 is welded at the rear end of the pipe body 1, rubber 4 is wrapped and sealed in the outer circle surface between the front end circular plug plate 2 and the rear end circular plug plate 3 and forms a conical round table shape, a screw rod 5 is connected between the front end circular plug plate 2 and the rear end circular plug plate 3 in a penetrating mode along the center, a locking nut 6 is screwed and connected to the screw rod 5 on the outer surface of the front end circular plug plate 2 and the rear end circular plug plate 3, a pull ring 7 is arranged at the tail end of the screw rod exposing the rear end circular plug plate 3, and the pull ring 7 can be.
And (3) submerging the assembled bypass valve water intake steel rubber plug to the bypass valve water intake by a diver, putting the bypass valve water intake steel rubber plug into a water intake steel pipe, determining the position, and forcibly pushing to plug the pipeline. Because the steel rubber plug outside the bypass valve intake is made of rubber, the steel rubber plug has good sealing performance due to the acting force of water. The steel pipe plugging work is completed at one time. The secondary diving plugging is not needed.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
