Embodiment 3
Present embodiments provide a kind of locking type can plug with pressure fluid connector, the fluid connector is by implementing
The Male end connector that the terminative connector and embodiment 2 that example 1 provides provide is constituted, the right end and Male end connector of terminative connector
Left end be connector plug binding site.Male end connector and terminative connector adaptation principle are as follows:
One, Male end connector and terminative connector independently use sealing state:
The Male end connector and terminative connector of the fluid connector are during respective exclusive use, because inside it
Male end spring, female end spring resilience performance make male end abnormity valve member and female end valve body axle sleeve in position location to guarantee public affairs
The sealing performance of terminal adapter and terminative connector.Simultaneously the terminative connector steel ball be in female end collar bush taper hole it
In, steel ball locking spring is in steel ball lock sleeve and the unidirectional positioning states of female end collar bush, the lock of steel ball lock sleeve at this time
The axial plane of tight steel ball is in above steel ball, so that steel ball is in locking state.
Two, the connection procedure of Male end connector and terminative connector:
1, first the steel ball lock sleeve on terminative connector is pushed to the left and further compresses steel ball locking spring to steel ball lock
The steel ball lock sleeve positioning step of fixed left side (i.e. steel ball release positioning end face) contact female end shaft end set；In push process
In, the steel ball release slope step of steel ball lock sleeve is in above steel ball at this time, so that steel ball is in release conditions, steel ball can be in mother
Hold play above and below in the taper hole of collar bush；
2, during being inserted into Male end connector, the 4th sealing surface of plug and steel ball intermediate incline on male end collar bush make
Steel ball is obtained to scroll up in the taper hole of female end collar bush.The steel ball release slope step of the steel ball lock sleeve is contacted in steel ball
Steel ball intermediate incline on male end collar bush followed by steel ball form microgap dropped out so that will not fall during steel ball release
It goes.
3, until male end main shaft in by the female end collar bush of the male end collar bush insertion terminative connector of Male end connector
When the underface for the taper hole that steel ball locking groove is in female end collar bush on set, steel ball is caught in steel ball locking groove along taper hole；
Steel ball lock sleeve is pushed to the right end of Male end connector by steel ball locking spring and slides into steel ball release slope step and mother simultaneously
The steel ball lock sleeve positioning slope step on collar bush is held to form one direction positioning.The locking steel ball of steel ball and steel ball lock sleeve
Axial plane forms microgap.
Three, the Male end connector of fluid connector and terminative connector are being cooperatively connected:
The steel ball installed on groove and female end collar bush is locked by the steel ball on male end collar bush forms positioning.It is public at this time
Hold the third sealing surface formation sealing of the installing groove, male end sealing ring and female end valve body of sealing ring；The installation of female end sealing ring
4th sealing surface of groove, female end sealing ring and male end collar bush forms sealing；The peace of female end small sealing ring, female end small sealing ring
The third sealing surface for filling groove and female end valve body forms sealing.Male end collar bush push female end valve body axle sleeve is in female end spring
Strong compressive state, female end valve body push male end abnormity valve member make male end spring be in strong compressive state.At this time male end collar bush and
The inner flow passage of female end collar bush is in connected state.
Four, fluid connector is in Male end connector and terminative connector one or when all in residual voltage state:
Male end connector and terminative connector are during mating connection, the left end of male end collar bush and male end abnormity valve member
Face first touches the right side of female end valve body axle sleeve and female end valve body, with further, the male end collar bush push female end of insertion
Valve body axle sleeve compresses female end spring to the left, and female end valve body pushes male end abnormity valve member and compresses male end spring.Male end collar bush simultaneously
The 4th sealing surface of plug substitution female end valve body axle sleeve plug secondary sealing area with female end collar bush female end o-ring groove
It is formed and is sealed with female end sealing ring；The plug third sealing surface of female end valve body replaces the 5th sealing surface of plug of male end abnormity valve member
Installing groove and male end sealing ring with the male end sealing ring of male end collar bush form sealing.It is female in further insertion process
End small sealing ring slips over the small flow channels hole run through from inside to outside on female end valve body, and subsequent male end sealing ring also slides past female end valve body
On through small flow channels hole from inside to outside so that Male end connector and terminative connector are in connection state.In connection procedure
All sealing rings are all not exposed in runner, so will not be impacted by high-pressure fluid, solve current fluid connector band
The problem of pressing plug.
Five, the disconnection process of Male end connector and terminative connector:
Steel ball lock sleeve on first terminative connector pushes to the left further compresses steel ball locking spring to steel ball lock sleeve
Left end face contact female end shaft end set steel ball lock sleeve positioning step so that steel ball is in release conditions, the public affairs in connector
The thrust of spring and female end spring to Male end connector to the right is held, the steel ball locking groove for being detached from steel ball on male end collar bush,
Male end connector is detached from terminative connector, achievees the purpose that disconnection.The fluid connector is when male and female terminal adapter disconnects
It waits, each male end spring and female end spring can spring back to position location, guarantee original sealing surface, guarantee that circuit is not revealed.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
Determine the protection scope of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
It changes, improve, should be included within the scope of protection of this utility model.
