Abstract
The utility model discloses a multipath reversing valve which is small in operating force, small in internal leakage and low in manufacturing cost and has a simple machining process. The multipath reversing valve comprises an integral valve body with a rotating bucket joint and a movable arm joint, wherein the integral valve body is provided with three cut-through holes which are parallel with each other; a movable arm valve stem and a rotating bucket valve stem are arranged in two of the three cut-through holes; and threaded cartridge valve holes are formed in the two ends of the other cut-through hole, so that a main safety valve and an oil inlet check valve of the rotating bucket are arranged in the threaded cartridge valve holes.
Description
Technical field:
The utility model relates to a kind of engineering machinery, relates in particular to a kind of multiple directional control valve of engineering machinery.
Background technique:
Loader is a main machine in the engineering machinery, and national at present year sales volume is up to tens0000, and wherein 5T loader portion is maximum; The multiple directional control valve that existing 5T loader master joins is a hollow valve rod integral multi-way reversing valve, is a kind of comparatively novel product of the eighties exploitation, and its structure is simple relatively; But because swing arm and rotary valve pole all adopt the built-in one-way valve structures of hollow; Cause valve rod manufacturing process complicated, the valve rod manufacture cost is high, precision is difficult to guarantee, directly increases owing to bar simultaneously; Let out in causing big, steering force is big, rate of fault is high.
The model utility content
The purpose of the utility model is the deficiency that exists to above-mentioned existing technology, and a kind of multiple directional control valve is provided, this multiple directional control valve steering force is little, in let out for a short time, be easy to processing, cost is low.
The technological scheme of the utility model comprises the valve body that is respectively equipped with rotating bucket couplet and swing arm couplet; Said valve body is provided with three clear openings that are parallel to each other; Wherein two clear openings of said three clear openings are placed moving arm valve pole and rotary valve pole respectively, and its two ends of another clear opening are set to the thread cartridge valve opening, place the in line check valve that main safety valve and rotating bucket join respectively.
Offer balance balancing slit and throttling groove on said moving arm valve pole and the rotary valve pole respectively.
Said valve body is the integrated type valve body, and said valve rod is real core valve rod; The plane is provided with a thread cartridge valve opening on the said integrated type valve body, joins the one-way valve that promotes on the oil circuit in order to lay swing arm; Said its lower plane of integrated type valve body is provided with double-plate oilhole attachment face, and oilhole is communicated with the rotating bucket couplet respectively upward changes oil pocket and following commentaries on classics oil pocket, respectively in order to installation overload Fill valve.
It is three six general formulas that its rotating bucket of said valve body joins, and it is four six general formulas that swing arm joins.
Said swing arm joins for manual control, spring steel ball locate mode swing arm join, and it is that manual spring reset formula rotating bucket joins that said rotating bucket joins.
The utility model multiple directional control valve adopts monolithic construction, solid valve rod, thereby simple in structure; Manufacturing process is simple, and manufacture cost can descend 40% relatively, and valve body adopts advanced metal pattern forming method casting; Bent angle is big; Liquid flowing resistance is little, and the pressure loss is little, and internal leakage is little, steering force is little, rate of fault is low, the life-span is long.
