Technical Field
The utility model relates to a water gauge maintenance of equipment technical field, concretely relates to lead screw formula water gauge corer.
Background
With the development of technology, high-pressure automatic regulating water meters are widely used and installed in production pipe networks in the petroleum and petrochemical industries. The use precision of the water meter is often influenced by the reasons of the quality and the components of the fluid, and the water meter core is often cleaned, checked and maintained in the use process. In order to make the installed water meter and the process compact and beautiful, the process pipeline is relatively close to the ground, for example, in a multi-well type water distribution room of an oil field, the water meter has the condition that the inspection and the cleaning of the water meter core are abnormally difficult in the inspection and the cleaning work due to the fact that the water meter is too close to the ground. The reason is that the water meter core is taken out by poking the water meter core from bottom to top after the water meter pressure cap is removed. However, the water meter core is stuck to the water meter body due to the water quality and components of the fluid, and the water meter core can be poked out only by large impact force.
The current commonly used water meter core maintenance operation method is that after a water meter core pressing cap is removed, one person takes a punch and the other person takes a sledge hammer to impact the water meter core from bottom to top, so that the water meter core is taken out and maintained. However, in the operation process, the distance between the indoor water meter and the cement ground is often only 20CM, the thickness of the sledge hammer and the leakage length of the punch are subtracted by 10CM, and the collision distance of the sledge hammer is only 10 CM. Because operating space is little, and the operation degree of difficulty is very big, and the personnel of taking the punching pin are also injured the finger by pounding easily moreover, have increased the potential safety hazard in the operation process, use the sledgehammer to appear pounding partially easily simultaneously and cause the water gauge to damage. Chinese patent document CN201520538098 discloses a water meter coring device, which comprises a striking rod, a striking hammer and a fixing cap, wherein the striking hammer is provided with a central hole and is mounted on a rod body of the striking rod, one end of the rod body of the striking rod is provided with a backstop cap, the other end of the rod body of the striking rod is provided with a thread and is connected with the fixing cap, an external thread of the fixing cap is connected with a water meter shell, and the striking hammer can slide on the striking rod; this patent is through carrying repeatedly of percussion hammer and drawing the realization to the repeated striking and the vibrations of water gauge core, under the effect of fatigue stress, makes the water gauge core become flexible and throw off with the casing, and the effect principle and the effect of this patent are the same with artifical sledgehammer strikes, can cause the damage of water gauge equally.
Therefore, a flexible special extracting tool for the water meter core is needed to be designed.
