Abstract
The utility model relates to an inner core for a grouting and hole sealing device. The inner core comprises a one-way valve pipe connector, a friction welding layer, a fixing block, a ball valve, a spring, an annular rubber gasket and a pipe body, and is characterized in that the one-way valve pipe connector is arranged at one end of the pipe body; the friction welding layer is arranged between the one-way valve pipe connector and the pipe body; the one-way valve pipe connector is fixedly connected with the pipe body together through the friction welding layer; the outer wall diameter of the one-way valve pipe connector is equal to that of the pipe body; the inner wall diameter of the one-way valve pipe connector is bigger than that of the pipe body; steps are arranged on the inner wall of the one-way valve pipe connector; the outer end inner diameter of the one-way valve pipe connector is bigger than the inner end inner diameter; the fixing block, the ball valve and the spring are arranged in the one-way valve pipe connector; the ball valve is arranged between the fixing block and the spring. According to the inner core for grouting and hole sealing device, the pipe wall of the main pipe body is thin, the pipe wall of the one-way valve pipe connector is thick, so that the materials and the construction cost are reduced without affecting the use of the device; besides, the pipe body and the one-way valve pipe connector are formed through friction welding connection, so that the sealing property is good.
Description
Technical field
The utility model relates to a kind of fluid filling hole sealing device inner core.
Background technique
Inner core tube wall thickness for fluid filling hole sealing device of the prior art, heavy, consumptive material are large, price is high, work carrying is inconvenient, and inner side, inner core one end is provided with one-way valve, one-way valve is made up of spring, ball valve and fixed block, the ball valve of one-way valve is, by punching on inner core tube wall, ball valve is put into in-core at present, and then with artificial welding, manually welds often not prison welding and admittedly easily occur leakage phenomenon.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of fluid filling hole sealing device inner core is provided, the utility model solves the technological scheme that its technical problem adopts: structure of the present utility model comprises one-way valve tube joint, friction layer, fixed block, ball valve, spring, ring apron, body, the one end that it is characterized in that body is provided with one-way valve tube joint, between one-way valve tube joint and body, be provided with friction layer, one-way valve tube joint and body are connected and fixed by friction layer, the outer diameter of one-way valve tube joint equates with the outer diameter of body, the inner diameter of one-way valve tube joint is larger than the inner diameter of body, on the inwall of one-way valve tube joint, be provided with step, the outer end internal diameter of one-way valve tube joint is greater than inner end internal diameter, in one-way valve tube joint, be provided with fixed block, ball valve, spring, ball valve is arranged between fixed block and spring, one end of spring withstands on ball valve, the other end of spring withstands on one-way valve tube joint inner side step wall.
The beneficial effects of the utility model are, the tube wall of the utility model main body body is thin, the thickness of pipe wall of one-way valve tube joint, in the situation that not affecting use, can save material, reduce cost, body and one-way valve tube joint are formed by connecting by friction welding, good seal performance, and lightweight, when work, carrying is easily.
