Description
Technical field
The present invention relates to technical field of hydraulic pressure, especially a kind of Combined-type sheet-type slide valve system and combined method.
Background technique
Slide valve is slided on valve chamber sealing surface using spool, changes fluid inlet and outlet channel position to control fluid flow direction
Flow divider.Slide valve is usually used in the devices such as steam engine, hydraulic and air pressure, and movement mechanism is made to obtain the movement of predetermined direction and stroke
Or realize automatically continuously operating.Conventional slide valve has the tubular-type slide valve for being suitable for single oil circuit and the plate suitable for Multi-oil circuit at present
Formula slide valve, tubular-type slide valve, which needs that various valves connect together by pipeline, can form a holonomic system；And board-like slide valve needs
It is mounted on to be used together on the oil path block surface of customization and can just be combined into a holonomic system.Oil path block is non-standard, is needed
It is customized design according to demand, the slide valve of the type is simply possible to use in after processing, can not flexibly modify suitable for other kinds of
Slide valve does not have batch production characteristic.In particular with the increase for needing to control hydraulic device quantity, slide valve quantity demand increases
Add, corresponding oil path block design processing exponentially increases again, and processing cost has been significantly greatly increased.As production oil path block producer,
It needs to carry out each certain types of oil path block stock to produce with independent, occupies a large amount of inventory and resources of production, do not have
Standby flexibility and adaptability, delivery date are longer.
Summary of the invention
The applicant designs processing cost for needing cooperation non-standard oil path block to use existing for above-mentioned existing board-like slide valve
Greatly, flexibility and it is poor for applicability the disadvantages of, a kind of structurally reasonable Combined-type sheet-type slide valve system and combined method, the system are provided
Solenoid valve is arranged and is covered in lateral ends, saves a significant surface and can be used for the chip slide valves of several standards and splice and combine,
The requirement of single oil circuit or Multi-oil circuit can be met by not needing oil path block cooperation, to reduce design processing cost, be improved
Flexibility and applicability.
The technical solution adopted in the present invention is as follows:
A kind of Combined-type sheet-type slide valve system, a chip slide valve can be independently operated, or use at least two chip spool valve combinations,
Adjacent chip slide valve is allowed to dock in endface and sealing structure is utilized to realize sealing by fastening structure, makes adjacent chip slide valve
The oil suction chamber of valve inner, the corresponding connection of oil back chamber.
As a further improvement of the above technical scheme:
The two side ends that chip slide valve is arranged in solenoid valve cover.
The fastening structure includes the through-hole that perforation is respectively provided on the valve body of each chip slide valve, is worn using component of rod category
It crosses through-hole and locks each valve body.
The both ends of through-hole are counterbore.
The both ends of component of rod category are respectively positioned on valve inner.
Number of openings around oil suction chamber is more than the through-hole around oil back chamber.
The sealing structure includes that stepped hole is equipped at the oil inlet of valve body both ends of the surface, between two adjacent valve bodies
It is attached at the stepped hole of oil inlet using two way seal connector.
The outer peripheral surface of the two way seal connector is equipped with two seals slot, is nested with sealing ring in seal groove.
The sealing structure includes that gasket groove is arranged at oil return opening on the end face of the side of the valve body, in gasket groove
Sealing ring is set.
A kind of combined method of Combined-type sheet-type slide valve system uses cylinder between the adjacent chip slide valve at oil inlet
Sealing structure is sealed, and is sealed in oil return nozzle using plane sealing structure, keeps each chip sliding using fastening structure
Valve connection locking.
Beneficial effects of the present invention are as follows:
Solenoid valve of the invention is arranged on the left and right end cap of chip slide valve, can vacate one so effectively using end
Valve body is arranged for side-by-side series in face, the end face vacated, and makes it possible the independent assortment use of valve body, more fully utilizes
Each face of valve body reduces design processing there is no need to using oil path block that the combined and spliced of valve body can be completed to use
Cost improves flexibility and applicability, can be superimposed use according to actual needs.
The present invention is formed by the chip spool valve combinations of several standards, can need to combine different numbers according to practical oil circuit
The chip slide valve of amount, is freely combined in a flexible way, realizes the use of the chip spool valve combinations of plurality of specifications, has preferable
Scalability is improved suitable for new equipment research and development or the upgrading of matured product.Using standardized chip slide valve, convenient for reducing
The processing and manufacturing difficulty of single chip slide valve reduces the cost manufactured with inventory's stock to form standardized production.
Since oil inlet intracavity liquid is in high pressure conditions (usually 16 ~ 31.5MPA), the present invention is in adjacent chip slide valve
Between oil inlet accent at be arranged two way seal connector, using two way seal connector connect front and back two sections of oil suction chambers, pass through cylinder
The road sealing structure Shi Qiang junction has the sealing effect for being preferably directed to high pressure accent.Since liquid is in oil return accent
Low-pressure state (usually within 5Mpa), a side end face of oil return accent junction of the present invention between adjacent chip slide valve
Upper setting planar seal ring, meets the seal request of low pressure accent.Since the connection of two adjacent chip slide valves needs simultaneously
Oil suction chamber and two accents of oil back chamber are penetrated through, thus the present invention is connected at high pressure accent (oil suction chamber) using the connector that cylinder seals
Part, and the sealing ring of flat seal is used only at low pressure accent (oil back chamber), both avoided while being connected using two cylinder sealings
Assembly difficulty caused by fitting, while also avoiding simultaneously using high pressure oil seepage caused by flat seal, it can be simultaneously
Meet the requirement of craftsmanship and leakproofness.
The present invention is internally provided with mutual corresponding through-hole in each chip slide valve, and hexagon socket head cap screw passes through through-hole will be each
Chip slide valve connects into an entirety, and the other end tightens fixation with nut, easy to operate, and can guarantee sealed precision.
Bolt and nut are respectively positioned on the inside of valve body, will not impact to external element is arranged in, practicability is good.Multiple through-holes are set
The oil inlet accent periphery for being placed in high pressure guarantees the leakproofness of oil suction chamber, oil return after each chip slide valve is fixed with bolt
Accent periphery utilizes the coupling mechanism force for the bolt being arranged with oil inlet accent adjacent, can satisfy the seal request of low pressure accent.This
Fastener is set up directly on oil inlet accent periphery by invention, rather than is simply provided in the four corners of chip slide valve valve block, both
The reasonable utilization inner space of valve block, while coupling mechanism force can also be provided to accent sealing device, it avoid frequent charge and discharge
Fastener dynamic fatigue caused by hydraulic coupling changes loosens, and effectively increases the sealing effect and reliability of equipment.
