Reliably place flexible gas nozzle 4.
Flexible gas nozzle 4 is a tight fit in gas nozzle jack 31.Here, it should be noted that flexible gas nozzle 4 and gas nozzle jack 31
Tight fit can be understood as flexible gas nozzle 4 and is interference fitted with gas nozzle jack 31, that is to say, that the radial dimension of flexible gas nozzle 4 omits
More than the radial dimension of gas nozzle jack 31.Gas nozzle 4 flexible in this way can be firmly secured in gas nozzle jack 31 blanket gas simultaneously
Mouth jack 31.
Flexible gas nozzle 4 is communicated with gas passage 22, for example, one end of flexible gas nozzle 4（Such as the right end in Fig. 1）It may be inserted into
In one end of gas passage 22（Such as the left end in Fig. 1）, flexible gas nozzle 4 is made 2 preferably to coordinate with interrupting, so as to which gas can be in gas
It flows, and even if interrupting 2 slight oscillatories between body channel 22 and flexible gas nozzle 4, is inserted since flexible gas nozzle 4 is a tight fit in gas nozzle
Reason in hole 31 will not impact the sealing of gas, not only reduce the processing and assembling of docking facilities 100 in this way
Precision so as to reduce cost, and substantially increases the production qualification rate and production efficiency of docking facilities 100.
In an embodiment of the present invention, it is to be understood that flexible gas nozzle 4 itself has flexible characteristic, it will be understood that
Here flexibility is for rigidity, that is to say, that flexible 4 relative stiffness gas nozzle of gas nozzle is softer, can be one
Determine to realize deformation in degree, can thus make flexible air mouth 4 and 2 preferably cooperations and sealing of interrupting, even if interrupting 2 slightly
It swings, the sealing of gas will not be impacted.
Docking facilities 100 for outlet valve according to embodiments of the present invention, by setting flexible gas nozzle 4 and flexible gas nozzle
4 with 31 tight fit of gas nozzle jack, and the leakproofness both so as to improve, will not be to docking facilities even if interrupting 2 slight oscillatories
The sealing of gas in 100 impacts, and not only reduces processing and the assembly precision of docking facilities 100 in this way, and significantly
Improve the production qualification rate and production efficiency of docking facilities 100.
In one embodiment of the invention, flexible gas nozzle 4 can be silica gel gas nozzle.Certain present invention includes but not limited to
This, other flexible materials can also be used in flexible gas nozzle 4,2 preferably coordinate and seal as long as can realize flexible gas nozzle 4 and interrupt
Flexible material both falls within protection scope of the present invention.
As depicted in figs. 1 and 2, the boss 41 of annular can be equipped on the peripheral surface of flexible gas nozzle 4.Boss 41 can be preferably
Make to be interference fitted between flexible gas nozzle 4 and gas nozzle jack 31, so as to so that flexible air mouth 4 is more stably located at gas nozzle jack 31
It is interior and can preferably seal gas nozzle jack 31.
Preferably, boss 41 can be multiple and be separated from each other in the axial direction of flexible gas nozzle 4.It is it is understood that convex
The quantity of platform 41 can specifically be set according to the concrete condition of docking facilities 100.Multiple boss 41 are in the axial direction of flexible gas nozzle 4
On be separated from each other, multi-sealing structure can be formed in this way, gas nozzle jack 31 is preferably sealed, avoid gas leakage.
According to one embodiment of present invention, barb structure 42 can be equipped on the peripheral surface of flexible gas nozzle 4, as shown in Fig. 2,
Barb structure 42 is annular and is located on the peripheral surface of the flexible gas nozzle 4, what barb structure 42 can be extracted towards flexible gas nozzle 4
Direction extends.Barb structure 42 can be such that flexible air mouth 4 preferably coordinates with gas nozzle jack 31 as a result, so as to more preferable close
Docking facilities 100 are sealed, and can prevent flexible gas nozzle 4 from situation about coming off occur, improve the stability of docking facilities 100.
It is understood that barb structure 42 may be multiple, multiple barb structures 42 can be in the axial direction of flexible gas nozzle 4
On be uniformly distributed, can form multi-sealing structure in this way, promote the sealing effect of docking facilities 100, and be better protected from soft
Property gas nozzle 4 comes off.
As depicted in figs. 1 and 2, at least part of flexible gas nozzle 4 is configured to taper.Pyramidal structure can be better achieved
Interference fit between flexible gas nozzle 4 and gas nozzle jack 31, so as to so that flexible air mouth 4 is more stably located at gas nozzle jack 31
It is interior and can preferably seal docking facilities 100, and one end of flexible air mouth 4 can be made（Such as the right end in Fig. 1）It can be more
It is readily inserted into one end of gas passage 22（Such as the left end in Fig. 1）, realize 2 flexible dockings with flexible gas nozzle 4 of interrupting.It can be with
Understand, flexible gas nozzle 4 also may be configured to cone-shaped air tap.
According to one embodiment of present invention, docking facilities 100 may also include pressing plate 5.Pressing plate 5 is located at gas nozzle fixed plate 3
On the side of mounting base 1, that is, in Fig. 1 on the left side of gas nozzle fixed plate 3.It is understood that pressing plate 5 can be with
Gas nozzle fixed plate 3 is permanently connected together, such as is fixed together by way of riveting, and certain pressing plate 5 can also be with gas
Mouth fixed plate 3 is detachably connected, such as is linked together by buckle or the fixed mode of screw.
In one embodiment of the invention, pressing plate 5 is detachably connected with gas nozzle fixed plate 3, when usually using in this way
It can maintain easily, repair can be facilitated in damage, so as to reduce the working service cost of docking facilities 100.
There is through-hole 51 on pressing plate 5 and through-hole 51 is corresponding with gas nozzle jack 31, as shown in Figure 1, the radial dimension of through-hole 51
Less than the radial dimension of gas nozzle jack 31, it can prevent flexible gas nozzle 4 from exiting gas nozzle jack 31 in an axial direction in this way, so as to ensure gas
Excellent sealing at mouth jack 31.
Gas passage 22 is multiple with gas nozzle jack 31 and corresponds respectively.That is, multiple gas passages 22
It is corresponded with multiple gas nozzle jacks 31.For example, in one embodiment of the invention, as shown in Figure 1, gas passage 22 and gas
Mouth jack 31 is three and corresponds respectively, and docking facilities 100 according to embodiments of the present invention can be described as three holes as a result,
Docking facilities.
To sum up, the docking facilities 100 for outlet valve according to embodiments of the present invention, by setting flexible gas nozzle 4
And flexible gas nozzle 4 and 31 tight fit of gas nozzle jack, the leakproofness both so as to improve, will not even if interrupting 2 slight oscillatories
The sealing of gas in docking facilities 100 is impacted, and boss 41 and/or barb structure are set on flexible gas nozzle 4
42, gas nozzle jack 31 can be preferably sealed, and can prevent flexible gas nozzle 4 from exiting gas nozzle jack 31 in an axial direction, so as to drop
