Interior valve core housing 5.In this manual, for ease of description, towards the one of male joint when " front " refers to that female joint is connected with male joint
Side, when " afterwards " refers to that female joint is connected with male joint away from male joint side.
Segmented head 2 is arranged on the front side of housing 1, and rear side is inserted in the front side of housing 1, the leading section of joint pedestal 4
It is inserted in segmented head 2, and periphery is provided with cutting ferrule 41,2 leading inside of segmented head is provided with bushing 21, and segmented head 2 is located at
Second back-moving spring 22 is provided between position and cutting ferrule 41 on rear side of bushing 21.
4 periphery of joint pedestal is arranged with sleeve 6, on rear side of cutting ferrule 41, and in 41 correspondence of cutting ferrule, the leading section of sleeve 6
Periphery is arranged with core retainer plate 7, is provided with (the first back-moving spring 61 between the rearward end and core retainer plate 7 of sleeve 6, and the leading section of core retainer plate 7 sets
Back-up ring 71 is equipped with, back-up ring 71 is coordinated with the medial wall of housing 1, so as to limit the position of core retainer plate 7 so as to solid with respect to 1 position of housing
It is fixed.Spring 23 is provided between the rearward end of core retainer plate 7 and segmented head 2.
Housing 1 offers air inlet 11 on the side wall of rearward end, with 11 phase of air inlet on the lateral wall of joint pedestal 4
To position be radially recessed air channel 42, air channel 42 is extended axially forward along joint pedestal 4, until it reaches sleeve
6 rearward end, so that the rearward end of sleeve 6 and air inlet 11,1 ft connection of housing.
The periphery of valve core housing 5 is provided with spring 51, and one end of spring 51 is abutted with the rearward end of valve core housing 5, the other end with
The medial wall of joint pedestal 4 abuts, thus, it is possible to cause valve core housing 5 to keep the trend that side shifting resets backward.
Union joint 3 is arranged on the rear side of housing 1, and abutting part 31, the front side insertion of abutting part 31 are formed with its lateral wall
To in valve core housing 5 and joint pedestal 4, for abutting with the rearward end of joint pedestal 4, the rear side of abutting part 31 for blocking cap 32
Abut, blocking cap 32 is also fixed on 1 rearward end periphery of housing (mode being such as threaded connection), thus defines union joint 3
Position.Union joint 3 is inserted partially in valve core housing 5 positioned at abutting part 31, is provided with valve element 8 and valve seat 9, valve in union joint 3
Bar 10 is located in valve seat 9 through the rearward end after valve element 8, valve element 8 can relative to union joint 3 in the axial direction of snap joint straight line
It is mobile, and valve seat 9 is then fixed in union joint 3, is respectively provided with gap between valve element 8 and valve seat 9 and union joint 3, in order to fluid
Pass through.The leading section of valve rod 10 is then extended in valve core housing 5, and top 71 in order to male joint 7 abut, and male joint 7 is using existing
There is technology, as shown in Figure 4.
Valve element 8 offers valve opening 81 in hollow, and valve rod 10 is passed through from valve opening 81, and valve rod 10 is located at the portion on front side of valve opening 81
Point enlarged diameter portion 101 is formed with, the diameter with diameter greater than valve opening 81 of the enlarged diameter portion 101, the thus diameter of valve rod 10
Increase portion 101 can be abutted with around the leading section of valve opening 81, so as to when valve rod 10 is promoted to rear side, can promote simultaneously
The side shifting backward of valve element 8.Limiting section 33, the leading section of valve element 8 and valve seat are convexed to form on the medial wall of union joint 3 radially-inwardly
The 3rd back-moving spring 82 is provided between 9 leading section so that valve element 8 remain abut with limiting section 33 forward so as to
So that the space fluid that 8 both sides of valve element are located in union joint 3 is obstructed.When side shifting leaves limiting section 33 to valve element 8 backward, connection
The spaces that 8 both sides of valve element are located in 3 connect, with the gap formation fluid between valve element 8, valve seat 9 in valve core housing 5, union joint 3
Path so that two conducting of snap joint.The radially inner side wall of limiting section 33 can be inclined-plane, from front to back gradually radially outward
Incline, the valve rod 10 that is thus promote valve element 8 backward side shifting when, fluid passage is gradually opened, and Fluid pressure is gradually reduced.
Offer valve seat orifice 91 in valve seat 9, the rearward end of valve rod 10 in initial position with the rearward end of valve seat orifice 91 it
Between there is a certain distance so that 10 opposite valve seat 9 of valve rod has certain activity space.9 company of being fixedly installed on of valve seat
In joint 3, in the present embodiment, the rear side of valve seat 9 is provided with leg 92, leg 92 towards union joint 3 rear side gradually radially
Stretch out, until abut with the medial wall of union joint 3, the medial wall of union joint 3 indent at the abutting, so as to define valve seat
9 position.Leg 92 is 3 in the present embodiment, it is also possible to select other quantity as needed, between having between leg 92
Every so that fluid passes through.
During use, by male joint 7 from segmented head 2 insert until with segmented head 2 on the inside of be fixed, while male joint 7
Top 71 top is to valve rod 10 so that the side shifting backward of valve rod 10, while the 3rd back-moving spring 82 is compressed, so as to promote valve element 8
Leave the limiting section 33 in union joint 3, thus fluid can from 8 periphery of 3 medial wall of union joint and valve element, 3 medial wall of union joint and
Gap between 9 periphery of valve seat passes through, until it reaches the pipeline connected on rear side of union joint 3, and once-through operation can be completed.
When needing to disconnect, air can be passed through from the air inlet 11 of housing 1, air is along the sidesway forward of air channel 42
Dynamic, until it reaches the rearward end of sleeve 6, with the increase of air pressure, sleeve 6 is promoted to front side by air, while first is multiple
Position spring 61 is compressed, until the leading section of sleeve 6 is abutted with the cutting ferrule 41 of 4 front end periphery of joint pedestal, and promotes cutting ferrule 41
Side shifting forward, while second back-moving spring 22 is compressed, so as to by the male joint 7 in segmented head 2 to front side (outside segmented head 2)
Promote so that male joint 7 and female joint depart from, after valve rod 10 is no longer influenced by the active force of male joint 7, valve element 8 is multiple the 3rd
Resetting to front side in the presence of the spring 82 of position causes the fluid passage in union joint 3 to close, and the fluid in female joint will not flow out
To outside.After stopping ventilation, in the presence of second back-moving spring 22, side shifting resets cutting ferrule 41 backward, and sleeve 6 is then the
In the presence of one back-moving spring 61, side shifting resets backward.In case of emergency also manually snap joint and male joint 7 can be taken off
Open.
