Problems solved by technology

At present, in the centralized distribution and switching of liquid flow, manual gate valves or electromagnetic gate valves are mostly used to assemble and integrate to meet the requirements. In this way, the more target points, the more pipe networks, the more gate valves are required, and the more difficult the assembly and integration are. The larger the space, the higher the input cost, and the higher failure rate, the maintenance is extremely inconvenient, which limits the development of multi-objective applications

Abstract

The invention relates to a centralized distribution multiway switching valve, and belongs to the field of agricultural and forestry greening machinery. The centralized distribution multiway switchingvalve comprises a valve sleeve, a valve core, a left end cover, a right end cover, a sealing ring I and a sealing ring II; and the valve core is mounted in the valve sleeve in a clearance fit mode, the left end cover is fixed on the left end face of the valve sleeve, the right end cover is fixed on the right end face of the valve sleeve, and the valve core is connected with the left end cover andthe right end cover through bearings; the sealing ring I is mounted on the left end cover and the right end cover and is used for preventing leakage between the left end cover and the right end coveras well as the valve sleeve; and the sealing ring II is mounted on a left shaft shoulder and a right shaft shoulder of the valve core. According to centralized distribution multiway switching valve, the number of paths can be selected according to requirements, and the paths are allocated to any target supplying place; and required driving elements are less, the valve integration is high, the structure is compact, reliability is high, and maintenance is convenient.

Description

technical field [0001] The invention relates to a centralized distribution multi-way switching rotary valve, which belongs to the field of agricultural and forest greening machinery. Background technique [0002] In the pumping process of irrigation, sprinkler irrigation, liquid fertilization, and pesticide spraying in agriculture, forestry, urban greening, medicinal material planting, greenhouse planting, etc., it is necessary to switch and distribute the liquid flow according to different target points. At present, in the centralized distribution and switching of liquid flow, manual gate valves or electromagnetic gate valves are mostly used to assemble and integrate to meet the requirements. In this way, the more target points, the more pipe networks, the more gate valves are required, and the more difficult the assembly and integration are. The larger the space, the higher the input cost, and the higher the failure rate, the maintenance is extremely inconvenient, which li...
