The utility model discloses the low problem that easily takes place the seepage of single channel sealing joint life -span among the hydraulic system of long -term pressurize of can solving.
Description
Technical field
This utility model is related to a kind of snap joint, and in particular to a kind of double sealing snap joint, and it can be in connection
There are two seals during connection, be mainly used in needing the pulse hydraulic pipe-line system that long-term pressurize and maintenance are convenient to mount and dismount.
Background technology
At present in the high-pressure pulsating hydraulic system for needing long-term pressurize, snap joint is generally added using one O-ring seals
The sealing structure of politef back-up ring, due to hydraulic medium to sealing member it is long when pulsatile impact, easily cause sealing member
Deformation or damage, so as to cause the external leakage of snap joint, affect the normal work of hydraulic machinery.
Utility model content
The purpose of this utility model is to provide a kind of double sealing snap joint, and it can solve the hydraulic pressure of long-term pressurize
The single channel seal nipple life-span low easy problem that seepage occurs in system.
This utility model solves the technical scheme adopted by its technical problem：
A kind of double sealing snap joint, the snap joint include that famale connector and front end are arranged in the famale connector
Male contact, the periphery of the male contact are provided with V-shaped groove, and the periphery of the famale connector is provided with for making steel ball fall into the V-arrangement
Gland and lock sleeve in groove, is provided with spring, is equipped with the male contact and famale connector between the gland and lock sleeve
Valve seat and nonreturn valve core, are provided with big O-ring and little O-ring between the male contact and famale connector, the little O-ring is arranged on
The front end of male contact, the front end periphery of the male contact are provided with the radius arcuate groove consistent with little O-ring radius, the male contact
Rear end against little O-ring between famale connector is provided with back-up ring.
By above-mentioned technical proposal, the back-up ring is politef back-up ring.
This utility model, has the advantages that：The snap joint is by arranging two between male contact and famale connector
Road O-ring is sealed, and big O-ring is radial compression sealing structure, and at the little O-ring in front end adds one back-up ring, for preventing
Only little O-ring is under the effect of high-pressure pulsating medium, the fit clearance being squeezed between male contact and famale connector, and cause little O shapes
The damage of circle, even if little O-ring deformation or damaged, a small amount of working media flows out, but the pressure of working media is reduced, rear end
Big O-ring can play interception sealing function, it is to avoid the leakage of working media；Meanwhile, the front end of male contact is opened up into arc
Groove, when little O-ring is acted in high-pressure pulsating medium, is adjacent to the arcuate groove of male contact, can prevent little O-ring because of elastic deformation
It is unable to resilience to restore and do not have sealing function.This utility model can improve the service life of snap joint, and prolongation quickly connects
The replacement cycle of head, the device systems repair time is reduced, improve operating rate, can also avoid causing because of the external leakage of snap joint
Unit exception, reduce equipment failure rate, reduce the latent fire hazard that causes of hydraulic leak and injection injury, improve in running
Safety coefficient.
Description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the structural representation of this utility model embodiment.
In figure：1- male contacts, 2- valve seats, 3- glands, the big O-rings of 4-, 5- back-up rings, the little O-rings of 6-, 7- lock sleeves, 8- are mono-
To valve element, 9- famale connectors.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit this utility model.
In preferred embodiment of the present utility model, as shown in figure 1, a kind of double sealing snap joint, the snap joint
The male contact 1 being arranged on including famale connector 9 and front end in famale connector 9, the periphery of male contact 1 are provided with V-shaped groove, outside famale connector
It is provided with week for making the gland 3 and lock sleeve 7 that steel ball fallen in V-shaped groove, between gland 3 and lock sleeve 7, is provided with spring, sun
Valve seat 2 and nonreturn valve core 8 are equipped with joint 1 and famale connector 9, big O-ring 4 and little between male contact 1 and famale connector 9, is provided with
O-ring 6, little O-ring 6 are arranged on the front end of male contact 1, and the front end periphery of male contact 1 is provided with radius with 6 radius one of little O-ring
The arcuate groove of cause, the rear end between male contact 1 and famale connector 9 against little O-ring 6 are provided with back-up ring 5.
In preferred embodiment of the present utility model, as shown in figure 1, back-up ring 5 is politef back-up ring.
As shown in figure 1, installation steps of the present utility model are as follows：
When pipeline passive state is attached, rotary locking cover 7 is pulled back and is unclamped afterwards in place, then pulls back dynamic pressure
Set 3 in place after, male contact 1 is inserted in famale connector 9, gland is unclamped, gland is travelled forward pressure steel ball under spring force,
In the V-shaped groove of steel ball press-in male contact 1, male contact 1 is blocked, promote forward and rotary locking cover 7, pin gland 3, prevent gland
3 mistakes for retreating and producing are disengaged, and nonreturn valve core 8 is retreated simultaneously, open check valve core 8, form annular medium flow channels, big O
Shape circle 4 and little O-ring 6 produce elastic deformation, seal male contact 1, connect fluid circuit；
When pipeline passive state is turned off, rotary locking cover 7 is pulled back and is unclamped afterwards in place, then pulls back dynamic pressure
After covering 3 in place, male contact 1 is disengaged in the presence of 8 spring force of nonreturn valve core and external force from famale connector 9, and nonreturn valve core 8 is in bullet
Spring force effect under travel forward, 8 sealing ring of nonreturn valve core respectively with 9 conical surface seal of male contact 1 and famale connector, prevent working media
Outflow, disconnect fluid circuit.
This utility model improves the service life of snap joint, extends the replacement cycle of snap joint, reduces and set
Standby system overhaul time, it is to avoid because of the unit exception that the external leakage of snap joint is caused, improve the safety in running
Coefficient.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
