Description
Technical Field
The utility model relates to a multiple unit valve especially relates to a novel large-traffic multiple directional control valve of high pressure.
Background
The multi-way reversing valve is a combined valve with two or more reversing valves as main bodies. The reversing valve is a valve which changes the on-off relationship of an oil duct connected to a valve body by means of the relative movement between a valve core and the valve body. According to different working requirements, auxiliary valves such as a safety overflow valve, a one-way valve, an oil replenishing valve and the like can be combined. The multi-way reversing valve in the market at present has smaller flow capacity, can not improve output flow, and has poorer adaptability.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned defects, the present invention provides a novel high-pressure large-flow multi-way directional valve with large flow capacity.
In order to achieve the above object, the utility model discloses a following technical scheme realizes: novel high-pressure large-flow multi-way reversing valve, including inlet valve, oil return valve, be equipped with a plurality of switching-over valves between inlet valve and the oil return valve, all be provided with the connecting hole on the valve body of inlet valve, a plurality of switching-over valves and oil return valve, just the connecting hole is connected as an organic whole with inlet valve, a plurality of switching-over valves and oil return valve through bolt and nut cooperation fastening, the relief valve is installed to the one end of inlet valve body, connect through the oil duct between adjacent inlet valve, switching-over valve, the oil return valve, still be equipped with the confluence valve between two wherein switching-over valves, be equipped with supplementary oil inlet on the confluence valve, the confluence valve is connected through the oil outlet way of check valve and left switching-over valve.
Furthermore, end covers are arranged at two ends of the reversing valve, and electromagnetic valves are arranged on the end covers.
Furthermore, a three-position and six-way valve is arranged in the reversing valve.
Furthermore, the joints of the oil inlet valve, the oil return valve and the reversing valve are sealed by rectangular sealing rings.
Furthermore, the check valve consists of a spring seat, a spring and a valve, the valve is nested in the spring seat, and the spring is installed on the spring seat.
The utility model has the advantages that: the valve has the advantages of large flow capacity, convenient maintenance and repair and high rigidity and strength of the valve body. When the output flow is not enough, the extra oil supply pump of accessible is supplementary oil inlet fuel feeding to improve the output flow of work hydraulic fluid port, satisfy different mechanisms to different flow demands.
