Abstract
The invention discloses a multichannel hydraulic stacked connecting board, which comprises more than two channels for connecting different valve bodies, wherein the channels are all communicated with leading-out ports. Compared with the prior art, a hydraulic system can respectively or simultaneously carry out pressure detection and functional connection according to different needs just through the arrangement of the leading-out ports of the channels under the condition of not changing the combination and installation status of the valve bodies (any oil port can be independently led out to a needed control circuit), thus the switching over of the hydraulic system with different needs can be conveniently carried out in actual operations, the connecting board has no need to replace, the working efficiency is greatly improved, the errors are reduced, and the operating cost is objectively lowered. The invention has the advantages that the structure is simple, the manufacturing cost is low, and the operation and the use are convenient and fast.
Description
Technical field
The present invention relates to a kind of hydraulic element, relate in particular to a kind of multichannel hydraulic pressure overlapping connecting plate and have this multichannel hydraulic pressure overlapping connecting plate.
Background technique
At present, hydraulic pressure overlapping connecting plate has become a kind of general hydraulic element.Wherein, ISO4401-AB-03-4-A hydraulic pressure overlapping connecting plate includes three kinds of different model: MDC-01-PA-30; MDC-01-PB-30; MDC-01-AT-30.The hydraulic pressure overlapping connecting plate working principle of above-mentioned three kinds of different models respectively like Fig. 1,2, shown in 3, the function that can realize is respectively: to P, A; P, B; A, T carry out Pressure testing.
There is technical disadvantages in the hydraulic pressure overlapping connecting plate of above-mentioned three kinds of different models: can only carry out Pressure testing to certain specific two hydraulic fluid port; Can't take into account the Pressure testing of other hydraulic fluid ports; And can't carry out functional configuration, very flexible is often for realizing different functions, Pressure testing; Have to carry out integral replacing, inefficiency and the objective running cost that improved.In addition, each hole of superimposed plates top and bottom communicates, and the oil return of T mouth can only lack other flow direction through carrying out oil return in the duct that processes in the system's main valve piece that links to each other with it when overlapping was installed.
Summary of the invention
To the problem that exists in the existing technology, the object of the invention be provide a kind of compatibility good, multiple functional, need not frequent change in various different operating processes and simple cheap multichannel hydraulic pressure overlapping connecting plate.
For realizing above-mentioned purpose, technological scheme of the present invention is following:
A kind of multichannel hydraulic pressure overlapping connecting plate comprises the passage that connects different valve bodies more than two, and said passage all is communicated with draws port.
Further, the outlet that said passage connects different valve bodies is separately positioned on the relative two sides of said connecting plate with inlet, and the said port of drawing is arranged on the said connecting plate side that connects different valve bodies.
Further, on the relative two sides of said connecting plate or wherein the said outlet or the said inlet that are provided with of one side has O RunddichtringO slot hole, and the O RunddichtringO is housed in it.
Further, removably be provided with plug in said at least one passage.
Further, said plug is the plug screw that is threaded in the said passage.
Further, said drawing is provided with the fast access node structure that is used for connecting fast oil pipe on the port.
Further, said number of channels is 4.
Beneficial effect of the present invention is, the present invention compared with prior art, the present invention is under the situation that does not change valve body stack mounting state; Only, each passage draws port through being set; Make that hydraulic system can be according to different needs respectively or simultaneously a plurality of hydraulic fluid ports are carried out Pressure testing and be connected (control loop that arbitrary hydraulic fluid port all can lead to needs separately) with function, this has just made things convenient in the practical operation hydraulic system in various different demands, to switch, and need not change connecting plate; Improved working efficiency greatly; Minimizing makes mistakes, and has objectively reduced running cost, and the present invention is simple in structure, low preparation cost, easy for operation quick.

Embodiment
The exemplary embodiments that embodies characteristic of the present invention and advantage will be described in detail in following explanation.Be understood that the present invention can have various variations on various embodiment, its neither departing from the scope of the present invention, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the present invention.
Like Fig. 4-shown in Figure 7, the multi-functional Sandwich plate valve connecting plate 1 of 01 specification is hydraulic element.Material is selected 35 steel forgings for use.
This connecting plate 1 is a cuboid, and boundary dimension is set to: long 65, wide by 48, high 40.Identical with 01 serial prior standard Sandwich plate valve boundary dimension, connect, use with convenient, and elegant in appearance.
In connecting plate 1, be processed with P, A, B, four through holes 2 of T, the outlet of this P, A, B, four through holes 2 of T is separately positioned on the relative upper and lower plane 11,12 of connecting plate 1 with inlet.This P, A, B, four through hole 2 apertures of T are 6.3mm.In addition, on connecting plate 1, be processed with 4 mounting holes 3, mounting hole 3 apertures are 5.5mm.The position in above-mentioned 8 holes (P, A, B, four through holes 2 of T and 4 mounting holes 3) meets ISO4401-AB-03-4-A attachment face size requirement.
At connecting plate 1 lower plane 12, by the requirement of GB/T3452.1O RunddichtringO groove dimensions, be processed with 4 O RunddichtringO slot holes 21, this O RunddichtringO slot hole 21 and P, A, B, the coaxial correspondingly setting of four through holes 2 of T.An O RunddichtringO 4 is installed in each O RunddichtringO slot hole 21, and these O RunddichtringO 4 specifications are 9 * 1.8GB/T3452.1.
Inlet is processed with inner bolt hole G1/8 in the T hole of connecting plate 1 lower plane 12, in this inlet a plug screw 5 is installed, and these plug screw 5 specifications are G1/8A JB/ZQ4179.
Four sides at connecting plate 1 are processed with four respectively and draw port P1, A1, B1, T1, draw port P1, A1, B1, T1 for these four and communicate with P, A, B, T hole correspondingly respectively.Draw port P1, A1, B1, T1 aperture for four and be 6.3mm.
Draw port P1, A1, B1, the last quick inserting joint that is provided with of T1, also screw thread can be set in port, for four to make things convenient for connecting pipeline.The processing pattern is interior threaded hole M10 * 1 in the valve body end for P1, A1, B1, T1 hole, height of thread 10.Tapped hole is used for installing the PPT-2 pressure measuring tie-in and other connects the identical pipe joint of screw thread.
The typical application of the present invention in hydraulic system is described below:
As shown in Figure 8, the present invention and common overlapping hydrovalve are installed together use.The mounting point is between the pilot valve and main valve of ISO4401-AC-05-4-A electro-hydraulic reversing valve.There is seal ring one end to install downwards.
