Mouthful, be able to need not such as be installed according to choosing whether to install accumulator 1-9, then blocked with plug screw, because main valve body 1-1 is casting
Structure is made, the features such as boss, groove, rib are made full use of, stock utilization is high, compared with bar formula section bar, its material usage subtracts
Few about 35%.
As shown in figure 9, the center valve body 2-1 fronts of intermediate valve block 2 are provided with output oil port boss 2-1-1, it is defeated for processing
Oil-out 2-1-2, is connected with executive component.
As shown in Figure 10, center valve body 2-1 right flanks are sealing plane 2-1-3, with the intermediate valves of main valve body 1-1 or upper
The expansion interface plane of body 2-1 is connected, and is provided with the middle of pressure oil duct 2-1-4 and main valve body extension oil-out or upper one
The extension of valve body is communicated with oil road；It is provided with back oil road 2-1-5 and main valve body extension oil return opening or a upper center valve body
Extension is communicated with back oil road.
As shown in figure 11, center valve body 2-1 left surfaces are the 2-1-6 of expansion interface plane I, are provided with extension oil road 2-1-
7 and extension use back oil road 2-1-8, and processing seals counterbore in this two oil ducts end, for fill O-ring with it is next carry out it is close
Envelope.Additionally, being additionally provided with 4 crosses the straight-through right flanks of the 2-1-9 of nail II, to be connected with main valve body 1-1 with screw.
As shown in figure 12, counterbore 2-1-10 is provided with above center valve body 2-1, two-position three-way electromagnetic is processed at counterbore and is inserted
The dress 2-1-11 of valve opening II, for installing the 2-2 of two-position three-way electromagnetic inserted valve II, the usual inserted valve is normally closed type, center valve body
The trailing flank of 2-1 is provided with a groove 2-1-12, to reduce material, mitigate weight, because the structure of center valve body 2-1 makes full use of
Material, therefore, compared with the one of monoblock type, material usage reduces about 50%.
As shown in Figure 13,14, the rear end valve body 3-1 left surfaces of rear end valve block 3 are provided with 4 and cross the straight-through right sides of the 3-1-1 of nail III
Side, and counterbore 3-1-2 is provided with aperture, to allow head of screw to ensconce wherein, it is to avoid head of screw excessively exposes end face, plays
Beauty function, the rear end valve body 3-1 of rear end valve block 3 is identical with center valve body 2-1 blanks, in addition to left surface, remaining structure phase
Together, because rear end valve block 3 is last connection of oil sources valve, therefore left surface need not be as expansion interface plane, so being also not required to
Process the oil road and back oil road of extension.
As shown in Figure 15,16, decompression type main valve block 1A-1 is with the difference of overflow-type main valve block 1-1：Overflow-type master
Second pressure hydraulic fluid port 1-1-13 on valve body 1-1, changes and is processed as pressure-reducing valve jack, for installing decompression inserted valve 1A-2；Excessive
Overflow valve opening 1-1-14 on streaming main valve body 1-1, changes and is processed as safe valve opening, for installing safety valve 1A-3.Remaining structure
Both are identical, so both blanks are identicals, beneficial to scale cast blank.
When oil sources valve is two formula oil sources valve, then by 3 pieces of groups of end valve after an overflow-type main valve block 1 and in main valve
Check valve 1-6 is installed in the front of body 1-1, filter core 1-3 and filter head housings 1-2 is installed in the right flank of main valve body 1-1, in main valve body
Overflow valve 1-4, by-passing valve 1-5, the 1-7 of two-position three-way electromagnetic inserted valve I, pressure tap joint 1-8, plug screw 1- are installed above 1-1
10, accumulator 1-9, composition overflow-type main valve block 1 are installed in the trailing flank of main valve body 1-1；Wherein, pressure tap joint 1-8 and storage
Energy device 1-9, can require according to user, choose whether to install, and such as without installing, then be blocked with plug screw；In center valve body
The 2-2 of two-position three-way electromagnetic inserted valve II, composition intermediate valve block 2 are installed above 2-1；Two are installed above rear end valve body 3-1
The 2-2 of position threeway electromagnetic cartridge valve II, end valve block 3 after composition.
When oil sources valve is single-plicate oil sources valve, then overflow-type main valve block 1 is only needed to, and main valve body 1-1 left surfaces
Extension oil-out 1-1-10, extension oil return opening 1-1-11 and technique hydraulic fluid port 1-1-12 are blocked with plug screw.
When oil sources valve is two formula oil sources valve, then by an overflow-type main valve block 1 with one after 3 pieces of end valve constitute, it is logical
Cross screw 3-2 to be serially connected rear end valve block 3 with overflow-type main valve block 1, seal with O ring is used at interface plane.
When oil sources valve is multiple oil sources valve（Three or more than three, it is set to n connection）When, then by an overflow-type main valve block
1st, end valve block 3 is constituted after n-2 intermediate valve block 2 and one, by screw 3-2 after end valve block 3, n-2 intermediate valve block 2 with it is excessive
Streaming main valve block 1 is serially connected, and seal with O ring is used at each interface plane.Wherein, n is that oil sources valve valve joins number, in this way tri-coupling type
Oil sources valve, then n=3, intermediate valve number of blocks is 3-2=1, in this way 5-linked formula oil sources valve, then intermediate valve number of blocks is 5-2=3, successively
Analogize.
Described decompression type oil sources valve is essentially identical with the structure of overflow-type oil sources valve, is simply replaced with decompression type main valve block
Overflow-type main valve block 1.
The present invention has only used two kinds of blanks due to combined type oil sources valve, and blank dimension is less, is conducive to scale to cast
And reduce die cost；Due to construction standard, main valve body, center valve body and rear end valve body can as needed carry out batch and add
Work is produced, and flexibly constitutes the oil sources valve that various different valves join number, substantially increases production efficiency, shortens delivery cycle；Meanwhile,
Using fabricated structure, the big raising of stock utilization, and valve connection number is more, and stock utilization is higher, is conducive to saving into
This, increases the benefit.
