Problems solved by technology
The research on hydraulic rotary valves in Britain, the United States, and Germany was earlier, which is related to the survival and development of enterprises. There are few research and design articles on hydraulic rotary valves. Changes in the spool generate hydraulic power, which in turn affects the reliability and stability of the entire system
However, most of the above researches are carried out on slide valves and cone valves, and no breakthroughs have been made in hydraulic rotary valves with more complex flow states, and there are no applicable calculation methods or models.
At present, there are relatively few rotary valves used in traditional industries in my country, and an industrial chain has not been formed. There are very few rotary valves to choose from, which cannot meet the hydraulic control needs of various industries. If the traditional hydraulic system is used to form the control system, the structure is huge and the leakage point There are many fault points, slow control response, and the realization of human-controlled electronic control conversion is complicated. The industry urgently needs an excellent control structure to replace the traditional structure.

The invention discloses a multi-functional hand-operated and electric control rotary control valve. The multi-functional hand-operated and electric control rotary control valve comprises a control valve body, wherein a valve body right end cover and a valve body left end cover are connected to two sides of the control valve body separately; the control valve body is internally provided with a mainclutch control valve core and a secondary clutch control valve core symmetrically; one end, far away from the secondary clutch control valve core, of the main clutch control valve core penetrates through the valve body left end cover; and one end, far away from the main clutch control valve core, of the secondary clutch control valve core penetrates through the valve body right end cover. The multi-functional hand-operated and electric control rotary control valve is simple in structure, and simple and compact structure, high reliability, high work frequency, oil contamination resistance, noacceleration zero drift and other advantages can solve the operation and control problem; not only is automatic precise control achieved, but also manual control timely switch is also achieved; the purpose that the universal mechanism cannot realize can be effectively realized, mechanical-electric-hydraulic comprehensive utilization effectively realizes mutual switch and noninterference; and a control approach can be provided for intelligent machinery, and the multi-functional hand-operated and electric control rotary control valve can be combined with other oil path system for general utilization.
Description
technical field [0001] The invention relates to the technical field of control valves, in particular to a multifunctional flashlight integrated rotary control valve. Background technique [0002] The hydraulic rotary valve is a hydraulic valve that uses the spool to rotate relative to the valve body to realize the opening, closing and reversing of the oil circuit. The rotation of the rotary valve can be manually or by a stroke block, or it can be driven by a special drive device. drive. Compared with other hydraulic slide valves, hydraulic rotary valves are obviously different in terms of structural features and performance parameters. As a hydraulic control element, it has the advantages of simple and compact structure, high reliability, high operating frequency, anti-oil pollution, no acceleration and zero drift, etc., and can be widely used in hydraulic systems with high-speed reversing and high-speed excitation. The research on hydraulic rotary valves in Britain, the U...
