Description
Technical field
The utility model relates to hydraulic valve technology, especially a kind of basic valve block.
Background technique
Hydraulic integrated control valve block system is widely used in the hydraulic control of various engineering machinery, industrial machinery and agricultural machinery
Field processed is integrated in a variety of hydraulic valves on one six face connector, the internal punches of integrated package, and installation control opening and closing is inserted
Valve is filled, each valve group is connected into circuit, forms a typical hydraulic control circuit.This hydraulic manifold block is by hydraulic system
Structure is reduced to integrated package group form, have it is compact-sized, occupied area is small, it is easy to disassemble and maintenance, after mass production at
This low advantage；But it is big that there is also design efforts would simultaneously, and processing is complicated, and difficulty of processing is high, it is difficult to the disadvantages of secondary modification.Needle
For a type of equipment, needs to be customized integrated package design, the type equipment is simply possible to use in after processing, it can not be flexible
Modification is suitable for equipment improvement or other equipment.It is entire hydraulic in particular with the increase for needing to control hydraulic device quantity
The volume of integrated package substantially increases, and design difficulty of processing exponentially increases again, once there are localized design or manufacturing deficiency, often
It will lead to scrapping for entire integrated package, processing cost be significantly greatly increased.As the producer of production valve block, need to each spy
The valve block for determining type all carries out stock and produces with independent, occupies a large amount of inventory and resources of production, does not have flexibility and adapt to
Property.
Utility model content
The applicant is big for design efforts would existing for above-mentioned existing hydraulic manifold block, processing is complicated, difficulty of processing with
Integrated morphology increases and significantly increases, is difficult to modify, flexibility and the disadvantages of bad adaptability, provides a kind of structurally reasonable base
Plinth valve block, by the way that the dismantling of monolith integrated package at basic valve block and extension valve block, and after being standardized design, is passed through each module
Independent assortment the hydraulic integrated control valve block system structure of plurality of specifications can be realized mentioned to significantly reduce difficulty of processing
High flexibility and adaptability.
Technical solution used by the utility model is as follows:
A kind of basis valve block, basic valve block are equipped with oil inlet pipe and oil return pipe in inside, and oil inlet pipe and oil return pipe run through valve block
Ontology, and oil inlet nozzle and oil return nozzle are formed in valve block both ends of the surface, several valve openings are set inside basic valve block.
As a further improvement of the above technical scheme:
Stepped hole is equipped at oil inlet nozzle.
It is sealed at stepped hole using two way seal connector or one-way sealing connector.
It is equipped with gasket groove at the oil return nozzle of one side end face of the basic valve block, sealing ring is set in gasket groove.
In the basic valve block both sides of the face, fixation hole is set.
Fixation hole around oil inlet nozzle is more than the fixation hole around oil return nozzle.
The fixation hole is through-hole or threaded hole.
The both ends of through-hole are counterbore.
Basic valve block and at least one extension valve block or transition block are applied in combination, adjacent two valve block makes by fastening structure
Docked in endface and sealing structure utilized to realize sealing, be connected to oil inlet pipe inside adjacent valve block with oil return pipe correspondence.
Basic valve block directly uses, without cooperating adjacent valve block to use.
The beneficial effects of the utility model are as follows:
The basic valve block of the utility model can be applied in combination with extension valve block or transition block, and a basic valve block can root
According to the extension valve block for needing to combine different number, it is freely combined in a manner of more flexible, realizes the valve block combination of plurality of specifications

Valve block processes convenient for the manufacture of single valve block, reduces manufacture difficulty, standardization valve block can be made, forms standardized production,
Reduce the cost manufactured with inventory's stock.
Since oil inlet liquid in pipe is in high pressure conditions (usually 16 ~ 31.5MPA), the utility model is between valve block
Two way seal connector is set at oil inlet nozzle, connects the two sections of oil inlet pipes in front and back using two way seal connector, is sealed and tied by cylinder
Structure makes line connection have the sealing effect for being preferably directed to high pressure pipe mouth.Since liquid is in low pressure shape in oil return nozzle
State (usually within 5Mpa), setting plane is close on a side end face of oil return nozzle junction of the utility model between valve block
Seal meets the seal request of low pressure nozzle.Due to two adjacent valve blocks connection need and meanwhile penetrate through oil inlet pipe with it is fuel-displaced
Two nozzles of pipe, thus the connector for joint that the utility model uses cylinder to seal in high pressure pipe mouth, and only make in low pressure nozzle
It with the sealing ring of flat seal, had both avoided while having used assembly difficulty caused by two cylinder sealed connecting components, while also having kept away
Exempt from while using high pressure oil seepage caused by two flat seals, wanting for craftsmanship and leakproofness can be met simultaneously
It asks.
Threaded hole is arranged inside basic valve block in the utility model, and setting is opposite with screw thread hole site inside extension valve block
Basic valve block and extension valve block are connected into an entirety by bolt by the through-hole answered, easy to operate, and can be guaranteed close
Seal precision.Through-hole, threaded hole and bolt are respectively positioned on the inside of module, will not impact to external element is arranged in, practical
Property is good.The utility model is arranged four bolts on the oil inlet nozzle periphery of high pressure and is fixed, and guarantees the leakproofness of oil inlet pipe, In
Oil return nozzle periphery is arranged three bolts and is fixed, and can satisfy the seal request of low pressure nozzle completely.The utility model will
Fastener is set up directly on oil inlet nozzle or oil return nozzle periphery, rather than the four corners in valve block are simply provided, both rationally
The inner space that valve block is utilized, while can also with line up sealing device provide coupling mechanism force, avoid frequent charge and discharge hydraulic
Fastener dynamic fatigue caused by power changes loosens, and effectively increases the sealing effect and reliability of equipment.The utility model exists
Transition block is set in extension valve block or basic valve block, the internal diameter of oil inlet pipe and oil return pipe to inside connection is converted, and is made big
Small valve block is connected with each other, and the fastening structure of transition block is matched with basic valve block and extension valve block simultaneously, smoothly realizes basis
The variable diameter linking objective of valve block and extension valve block, significantly improves the scalability of equipment.
