Multi-channel ball valve structure, electric ball valve and application of electric ball valve

Abstract

The invention discloses a multi-channel ball valve structure and an electric ball valve, and relates to the technical field of valves. The ball valve structure comprises a valve body, a valve ball anda valve cover, wherein a valve rod is connected with the valve ball, the valve body is provided with an inlet, an inlet II, an outlet I and an outlet II which are connected with a pipeline, the valveball is provided with a first channel, a second channel, a third channel, a fourth channel and a fifth channel, the inlet communicates with the first channel, the second channel and the third channelare 45 degrees, and the third channel and the fourth channel are 45 degrees, and the electric ball valve comprises the ball valve structure and an electric actuator. The invention further discloses an application of the electric ball valve. The multi-channel ball valve structure, the electric ball valve and the application of the electric ball valve have the beneficial effects that the size is small, the weight is light, the installation and maintenance are convenient, and four stop valves in the prior art are replaced; and at the same time, at least a double sealing structure is adopted, thesealing form is reliable, and the sealing effect of the ball valve is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a multi-channel ball valve structure, an electric ball valve and applications thereof. Background technique [0002] At present, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, and occupy a pivotal position in the national economy. [0003] Ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid, while the pipeline needs to control the confluence, diversion, and switching of the flow direction of the medium, requiring multiple valves to work together, such as deep diving equipment In the technical field, four manual shut-off valves are generally required to control the confluence, diversion, and flow direction switching of the mediu...

Problems solved by technology

[0003] Ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid, while the pipeline needs to control the confluence, diversion, and switching of the flow direction of the medium, requiring multiple valves to work together, such as deep diving equipment In the technical field, four manual shut-off valves are generally required to control the confluence, diversion, and flow direction switching of the medium on the drainage system pipeline of deep diving equipment. These four manual shut-off valves not only occupy a large space, but are inconvenient to operate, and the sealing effect is not ideal. , the flow resistance coefficient is large, which seriously affects the development prospects of deep diving equipment, so it is urgent to design a multi-channel integrated valve to replace the original four manual stop valve structure
