Description

Technical Field

[0001] The utility model relates to the field of ball valves, in particular to a support shaft type forged steel fixed ball valve. Background Art

[0002] At present, a Chinese utility model with announcement number CN215214838U discloses a fixed forged steel ball valve with good sealing performance, including a forged steel ball valve body, both ends of the forged steel ball valve body are fixedly connected with a first connecting flange, one side of the first connecting flange is provided with a plurality of first connecting holes, a sealing gasket is provided on the side of the first connecting flange away from the forged steel ball valve body, a through hole corresponding to the first connecting hole is provided on one side of the sealing gasket, a second connecting flange is provided on the side of the sealing gasket away from the first connecting flange, and a second connecting hole corresponding to the first connecting hole is provided on one side of the second connecting flange. The utility model is based on an ordinary forged steel ball valve, and is provided with a better sealing and secondary connection installation device, which solves the shortcomings of the fixed forged steel ball valve being prone to water leakage at the connection when connected to the pipeline and the difficulty in performing secondary connection installation on the fixed forged steel ball valve and the pipeline.

[0003] The existing fixed ball valve is not easy to maintain. After long-term use, the inside of the ball valve needs to be maintained to ensure the stability of the ball valve. The valve body of a general ball valve is fixed and installed by multiple bolts. During maintenance, tools are needed to disassemble and assemble it. The disassembly and assembly process is extremely troublesome, which increases the workload and reduces the efficiency of maintenance. It also does not have a backflow prevention function. A general ball valve only has the energy of switching on and off. In special usage scenarios, it is necessary to prevent the backflow of the transported material. Generally, a check valve is installed to prevent backflow, which not only increases the cost of use, but also increases the amount of maintenance in the later stage, reducing practicality. In order to solve the above-mentioned problems, we propose a support shaft forged steel fixed ball valve. Utility Model Content

After the maintenance is completed, the first valve body and the second valve body are installed, and the sliding rod drives the clamping rod to clamp with the clamping hole under the action of the first spring, and the way of fixing it can achieve the purpose of easy maintenance, reduce the workload, and improve the efficiency of maintenance. The flow blocking block is pushed open by liquid pressure, and the liquid flows normally. When the liquid pressure disappears, the flow blocking block is tightly attached to the limit ring under the action of the second spring, blocking the second ball, thereby achieving the purpose of preventing backflow, reducing the cost of use, and improving practicality. The second rotating shaft drives the second ball to rotate by rotating the rotating head, and it can be freely adjusted according to the direction of liquid inflow, which improves practicality and is convenient to use.
