Description

Multi-channel linkage combination valve

Technical Field

The utility model relates to a combination valve, in particular to multichannel linkage combination valve.

Background

Valves 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.

The patent number CN201920792382.4 discloses a combined valve of multichannel, has many fluid passage, can freely switch according to the technology requirement, and the application is extensive, intensification, modular design, installation is swift, programmable control, and degree of automation is high.

Although the above patent scheme solves the defects of the traditional multi-channel combination valve, the scheme still has some defects 1, most of the existing multi-channel combination valves have complex structures, are inconvenient to operate and control, have high processing difficulty, and have low practicability because the air flow conversion pressure is too high in the opening and closing process of the valve, thereby seriously affecting the adjustment quality of the valve; 2. the existing multi-channel combination valve cannot accurately regulate and control the opening and closing angle of the combination valve, and meanwhile, a valve rod of the combination valve is easy to accidentally move, so that serious potential safety hazards exist; to this end, we propose a multi-channel linkage combination valve to solve the above mentioned problems in the background art.
