Description

Sealing valve for circulation of solid-liquid mixture

Technical Field

The utility model relates to a sealing valve technical field especially relates to a sealing valve for solid-liquid mixture circulation.

Background

Valves (Valve) are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in piping systems. Valve tubing is technically the same as pumps and is often discussed as a separate category. The valve can be operated manually or by a hand wheel, a handle or a pedal, and can also be controlled to change the pressure, the temperature and the flow of the fluid medium. The valve can operate continuously or repeatedly for these changes, such as a safety valve installed in a hot water system or a steam boiler. In more sophisticated control systems, automatic control valves are employed as needed to regulate the changing set point of the flow through the pipeline from external inputs. The automatic control valve does not need manual operation and can accurately control various requirements of fluid media according to the input and the setting of the automatic control valve. The valves are further divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves and the like according to the material.
