Description
Technical field
The present invention relates to a kind of built-up joint, more particularly to a kind of built-up joint of hydraulic system, belong to engineering machinery skill
Art field.
Background technology
Hydraulic system is system more important in each system of engineering machinery, and whether its performance is stablized, and directly influences whole
The quality of machine performance.Hydraulic system is operated by this medium of hydraulic oil, and hydraulic oil flows out from hydraulic oil container, then flows
Through each element, hydraulic oil container is finally flowed back to, so circulation.To ensure the stability of hydraulic system function, it is often necessary to which it is entered
Row is safeguarded, needs to dismantle the joint between hydraulic system and hydraulic oil container when safeguarding, usual dismounting joint can cause a large amount of hydraulic pressure
The loss of oil, both sank money, cabin can be polluted again.First the hydraulic oil in hydraulic oil container is laid down sometimes and carried out again
Dismounting, but it is time-consuming, and secondary pollution easily is caused to hydraulic oil, it is unfavorable for reusing for later stage.Therefore, hydraulic system is being safeguarded
When, it is badly in need of one kind and is avoided that hydraulic oil is lost in, and easy to operate built-up joint.
The content of the invention
The present invention in order to be proposed the shortcomings that overcoming above-mentioned prior art to exist, its aim to provide it is a kind of it is simple in construction,
Built-up joint easy to operate, reliability is high.
Technical scheme：A kind of built-up joint, including pin end and female joint, the female joint are assemblied on fuel tank wallboard,
The pin end is engaged with female joint；The pin end radially uniformly opens up through hole A with female joint cavity overlapping；It is described
Female joint includes joint, unidirectional valve rod, reset element and ring flange；The joint is engaged with pin end and radially uniformly opened
If through hole B；The unidirectional valve rod, reset element, ring flange are arranged in order inside joint and along joint axial direction；It is described
Unidirectional valve rod axially moves under reset element effect relative to joint.
Preference, for the ease of making and the stability of structure, the cross section of the unidirectional valve rod is T fonts, and top is
Wedge type；The reset element is back-moving spring；The ring flange is assemblied in joint afterbody, and centre is provided with through hole C；It is described unidirectional
The intermediate throughholes C of valve rod through ring flange is axially moved.
Preference, in order to ensure the intensity of joint, the stub shaft uniformly opens up through hole D upwards.
Preference, in order to ensure the stability of hydraulic work system, it is S to make pin end cavity cross-sectional area, through hole A faces
Product is SA, the SA >=1.1S.
Preference, for reasonable Arrangement and ensure the stability of hydraulic work system, it is SB, the SB to make through hole B areas
≥1.5SA。
Preference, for further reasonable Arrangement and the stability of guarantee hydraulic work system, it is SB to make through hole B areas,
Through hole D areas are SD, the SB+SD >=1.7SA.
Beneficial effect：The built-up joint dismounting of the present invention is flexible, and reliability is high, the stream of hydraulic oil when effectively can prevent from safeguarding
Lose, and do not influence the performance of hydraulic system.
Brief description of the drawings
Fig. 1 is the exploded perspective view of built-up joint of the present invention；
Fig. 2 is schematic cross-sectional view when built-up joint of the present invention works；
Fig. 3 is schematic cross-sectional view after pin end of the present invention dismounting.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, 3, a kind of built-up joint, including pin end 1 and female joint 2, the female joint 2 are assemblied in fuel tank
On wallboard 3, the pin end 1 is engaged with female joint 2；The pin end 1 is radially uniformly opened with the cavity overlapping of female joint 2
If through hole A；The female joint 2 includes joint 21, unidirectional valve rod 22, reset element 23 and ring flange 24；The joint 21 and public affairs
Joint 1 is engaged and radially uniformly opens up through hole B；The unidirectional valve rod 22, reset element 23, ring flange 24 are located at joint 21
It is internal and be arranged in order along the axial direction of joint 21；The unidirectional valve rod 22 is under the effect of reset element 23, relative to joint 21
Axially move.The cross section of the unidirectional valve rod 22 is T fonts, and top is wedge type；The reset element 23 is back-moving spring；
The ring flange 24 is assemblied in the afterbody of joint 21, can according to the needs of the force value of reset element 23 adjustment position, and centre is provided with
Through hole C；The intermediate throughholes C of unidirectional valve rod 22 through the ring flange 24 is axially moved.The ring flange 24 is axially upper uniform
Open up through hole D.
It is front end to make pin end 1 be engaged end with female joint 2, in use, female joint 2 first is coated into fluid sealant, is reassembled
In on fuel tank wallboard 3, then load onto pin end 1, due to the front end of pin end 1 protrude it is longer, can effectively promote unidirectional valve rod 22 to
The afterbody of female joint 2 moves, so that through hole A enters the cavity of female joint 2.It is S, through hole A to make the cavity cross-sectional area of pin end 1
Area is SA, and through hole B areas are SB, and through hole D areas are SD, just because of SB+SD >=1.7SA, SA >=1.1S, can effectively be set logical
The distribution in hole and quantity, the intensity of built-up joint was both can guarantee that, and do not influenceed the performance of hydraulic system, hydraulic oil circulation is smooth.
When safeguarding hydraulic system, only lower pin end 1 need to be directly dismantled.Due to the removal of pin end 1, unidirectional valve rod 22 passes through reset element
23 effect, to the nose motion of female joint 2, until blocking the oil-out of female joint 2, hydraulic oil just can not be lost in, and then carry out
Corresponding maintenance work, fit on pin end 1 again after the completion of maintenance work is simply, convenient, reliably.
Although be described in detail above to the present invention in conjunction with the embodiments, those skilled in the art's energy
It is enough to understand, on the premise of present inventive concept is not departed from, above-described embodiment can also be changed or changed, such as be sent out this
Bright built-up joint is applied to other positions, solves Leakage, is still within the scope of the present invention.
