Description

Technical Field

[0001] The utility model relates to the technical field of valve installation, in particular to a positioning device for valve installation. Background Art

[0002] A valve is a mechanical device that controls the flow, direction, pressure, and temperature of a flowing fluid medium. Valves are basic components in piping systems. Valve fittings are technically the same as pumps and are often discussed as a separate category. Valves can be operated manually or with a handwheel, handle, or pedal. They can also be controlled to change the pressure, temperature, and flow of the fluid medium. Valves can operate these changes continuously or repeatedly, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used according to the needs of external inputs. Automatic control valves do not require manual operation and are based on their inputs and settings, allowing the valve to accurately control the various requirements of the fluid medium.

[0003] Currently, a valve is usually installed on a pipeline by manually holding the valve. During installation, the positioning accuracy of the valve and the pipeline is not high, the valve cannot be installed and fixed well, the installation efficiency is low, and the installation effect is not good. In response to the above problems, the inventors propose a valve installation positioning device to solve the above problems. Utility Model Content
