Description
Technical field
The invention belongs to Machine Design, is related to a kind of split type ball check valve.
Background technology
Existing common check valve is generally made of valve body, spool, spring, and there is oilhole at valve body both ends, be respectively fuel feed hole and
Oil outlet.Body cavity installs spool, and spool is gap-matched with valve body, forms sliding pair.Valve core inside is provided with logical oil
Road, when high pressure oil promotes spool, forms opening, thus fluid is open passes through.Therefore fluid can only be flowed from a direction.
Deficiency existing for this structure type is more independent in this one-way valve structures, and volume is larger, is not easy to system
It is integrated, and oil inlet position is fixed.In addition the opposite slip of spool and valve body, there are clamping stagnation risk.
The content of the invention
The purpose of the present invention is：There is provided a kind of small, anti-clamping stagnation, easy to the good split type steel of the system integration, versatility
Ball-type check valve.
The present invention technical solution be：A kind of split type ball check valve, including limited block 1, steel ball 2, check valve
Housing 3, casing 6, plug 7, its check-valve body 3, casing 6, plug 7 are split structure, and three is interconnected and sequentially tight
Fixed to put, the steel ball 2 is mobilizing exercises component, is movably arranged in check-valve body 3, and the oil inlet of check-valve body 3 is
Sealing can be contacted with steel ball 2 leads mouth, and the limited block 1 is arranged on 3 opening of check-valve body spacing, the institute that is used for steel ball 2
State and high pressure oil inlet is provided with casing 6.
3 opening of check-valve body is provided with oil outlet.
Check-valve body 3 and 7 outer surface of plug are provided with O-ring seals.
Check-valve body 3 and plug 7 are set in the mounting groove of O-ring seals is provided with guard circle at the same time.
Described sleeve pipe 6 is discrete interconnected several, and high pressure oil inlet is provided with some casing.
When 3 fluid of check-valve body is flow backwards, steel ball 2 is promoted, it is led mouth with check-valve body 3 and contacts that to form line close
Envelope.
Beneficial effects of the present invention：The split type ball check valve of the present invention, using split structure, by more casing replacing,
Change casing length and high pressure oil inlet position, realize the adjusting of check valve oil inlet position, substantially increase the general of check valve
Property and design flexibility, while using after split-type design, check valve handling ease is easy for installation, effectively increases product
Craftsmanship and economy.In addition, the split component of the split type ball check valve of the present invention does not have external shell, can be directly integrated
It is versatile into the hydraulic system of corresponding size, have a wide range of application, there is larger actual application value.
Brief description of the drawings
Fig. 1 is the split type ball check valve structure diagram of the present invention,
Wherein 1 is limited block, and 2 be steel ball, and 3 be check-valve body, and 4 be O-ring seal, and 5 be guard circle, and 6 be casing, 7
It is plug.
Embodiment
Below by specific embodiment, the present invention is described further：
Referring to Fig. 1, it is for the split type ball check valve structure diagram of the present invention.The split type ball check valve
Including limited block 1, steel ball 2, check-valve body 3, casing 6, plug 7.Wherein, the check-valve body 3, casing 6, plug 7 are
Split structure, three are interconnected and sequentially fasten setting, therefore the tune of easy to process, installation and removal and oil inlet position
Section.
The inside of check-valve body 3 is step pore structure, and aperture major part is through hole, and aperture smaller portions are oil inlet
Mouthful, be provided with oil outlet at via openings, at oil inlet for can contact with steel ball 2 seal lead mouth.
The steel ball 2 is mobilizing exercises component, is movably arranged in 3 through hole of check-valve body, has a diameter larger than check valve
The oil inlet diameter of housing 3, less than 3 hatch bore diameter of check-valve body.The limited block 1 is arranged on 3 opening of check-valve body
It is spacing for steel ball 2, avoid steel ball 2 from rolling out.
In addition, described sleeve pipe 6 is discrete interconnected several, and high pressure oil inlet is provided with some casing,
So that high pressure liquid oil can be with sleeve pipe inside.
The less end surface of 7 size of plug is smooth, and end is closely connected with casing, and other end size is larger,
And external screw thread is provided with, easy to load and unload.
In addition, the check-valve body 3 and 7 outer surface of plug are provided with O-ring seals, for hydraulic packing.Check valve
Housing 3 and plug 7 are set in the mounting groove of O-ring seals is provided with guard circle at the same time, prevents O-ring seals breakage from squeezing into seam
Gap.
In the split type ball check valve real work of the present invention, when 3 fluid of check-valve body is flow backwards, steel ball 2 is promoted, is made
It is led mouth with check-valve body 3 and contacts to form linear sealing, avoids fluid from flowing back.
Furthermore it is possible to replace the casing of different length or by becoming casing replacing number by dismantling plug, some casings are allowed
Concatenation, so as to change high pressure oil inlet position, to meet the needs of different hydraulic systems actual oil inlet position.Use split at the same time
Formula designs, therefore unidirectional valve housing, casing and plug can be processed respectively, therefore technique is simple, easy for installation, effectively improves
The craftsmanship and economy of product., can be with addition, the split component of the split type ball check valve of the present invention does not have external shell
It is directly integrated into the hydraulic system of corresponding size, it is versatile, have a wide range of application, there is larger actual application value.
