Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further with regard to technical scheme.It should be appreciated that this
The specific embodiment of place description is not intended to limit the present invention only to explain the present invention.
The present invention proposes a kind of stop valve.
In embodiments of the present invention, as shown in Figures 1 to 5, the stop valve includes valve body 10, cut-off valve element 20 and valve
Core 30, the valve body 10 includes the wing passage 13 that the main channel set with insertion and connection main channel are set, and main channel includes
First passage section 11 and second channel section 12 positioned at the both sides of wing passage 13.Cut-off valve element 20 offers valve assembly cavity 22,
Valve inside 30 is installed in valve assembly cavity 22, and valve activity space is left between valve inside 30 and the bottom of chamber of valve assembly cavity 22
23, the lateral surface of cut-off valve element 20 is arranged at intervals with the first sealing 251 and the second sealing 251, the first sealing 251 and the
The through hole 24 connected with valve activity space 23 is offered between two sealings 252.Cut-off valve element 20 is installed in first passage section
11 and can along main channel bearing of trend adjust, and make the second sealing 252 have conduction position and rest position, when second
Sealing 252 is in rest position, and the second sealing 252 and the inner wall sealing of first passage section 11 coordinate, by the He of through hole 24
Wing passage 13 separates, when the second sealing 252 is on position, the second sealing 252 and the inwall point of first passage section 11
From through hole 24 is connected with wing passage 13.
In above-mentioned, valve inside 30, also known as airtight core mainly use the function of its check valve, that is, applied in use
Appropriate pressure can be externally to injecting fluid media (medium) in the fluid system being connected with valve inside 30, and is to realize the check valve work(
Can, valve inside 30 has a plug in the one end being connected with fluid system, and during injection fluid media (medium), the plug needs
Toward away from outside direction movement, to open the air admission hole of valve inside 30, the function and structure for above-mentioned valve inside 30 is existing
The function and structure that valve inside 30 has in technology, therefore, the function and structure to valve inside 30 can refer to now in the present invention
There is the valve inside 30 of technology, be not discussed in detail herein.Based on this, in the present invention, valve inside 30 and valve assembly cavity
Valve activity space 23 between 22 bottom of chamber is then for staying certain mobile space to the plug, to ensure valve inside 30
Normally use.
Based on said structure, and Fig. 3 to Fig. 5 specific implementation structure is combined, this implementation has following several use states：
(1) as shown in figure 3, end valve element 20 dam end 21 be connected to second channel section 12 road junction when, stop valve
The cut-off second channel of core 20 section 12 and wing passage 13, now the second sealing 252 be on position, the second sealing 252 with
The inwall separation of first passage section 11, through hole 24 is connected with wing passage 13；
(2) as shown in figure 4, holding 21 processes separated with the road junction of second channel section 12 in damming for cut-off valve element 20, the
Two channel sections 12 and wing passage 13 are turned on, and now the second sealing 252 is in conduction position, the second sealing 252 and
The inwall separation of one channel section 11, through hole 24 is connected with wing passage 13；
(3) as shown in figure 5, further being separated with the road junction of second channel section 12 at the end 21 of damming of cut-off valve element 20, the
Two channel sections 12 and wing passage 13 are turned on, and now the second sealing 252 is in rest position, and the second sealing 252 and first is logical
The inner wall sealing of road section 11 coordinates, and through hole 24 and wing passage 13 are separated.
Understood based on above-mentioned use state, at dam end 21 and the road junction point of second channel section 12 of cut-off valve element 20
From, and through hole 24 by first passage section 11 inwall block when, that is to say that valve inside 30 is no longer connected with fluid system, therefore,
Even if fluid system causes pressure to increase because of factors such as temperature, influence will not also be produced on valve inside 30, so as to effectively prevent
Because leaking caused by the change of fluid system pressure.
Further, the first sealing 251 and the second sealing 252 offer annular mounting groove 26, annular mounting groove
26 are built-in with O-ring seal 27, and O-ring seal 27 is used to abut cooperation with the inwall of first passage section 11 to improve sealing effect
Really.
Further, the outside wall surface of cut-off valve element 20 also includes fastening face, and fastening face is provided with the first external screw thread 201, and

Now cut-off valve element 20 and valve body 10 are detachably connected, have the advantages that simple in construction, connection reliably, be convenient to mount and dismount.In addition, valve
The inwall of assembly cavity 22 is provided with the second internal thread 202, and the outside wall surface of valve inside 30 is provided with the be connected with the second internal thread 202
Two external screw threads, similarly, being detachably connected for cut-off valve element 20 and valve body 10 are realized using helicitic texture, it may have structure is simple
It is single, connection is reliable, the advantages of be convenient to mount and dismount.
Based on said structure, first passage section 11 is provided with retaining part 40, and the retaining part 40 is used to prevent cut-off valve element 20 from existing
Surprisingly screwed out during outward turning, to prevent the rotation of stop valve core 20 during moving back by whiz valve element by mistake.In this embodiment, retaining part
40 are connected to the first external screw thread 201 using helical structure, when needing to take out cut-off valve element 20, can first take out retaining part 40.
Preferably, that ends valve element 20 offers polygonal counterbore 28 towards outer end, in unloading process, using heavy with this
The polygon polygon spanner that hole 28 matches.Specifically, in the present invention, the counterbore 28 is hexagonal counterbore 28, and is being torn open
During unloading, dismantled using inner hexagon spanner.
Further, for ease of injecting fluid into fluid system, fluorinfused nozzle is connected with towards outer end in cut-off valve element 20
50, the cut-off valve element 20 is integrated setting or detachable separately positioned with fluorinfused nozzle 50, the preferred stop valve in the present invention is implemented
Core 20 is wholely set with fluorinfused nozzle 50, cut-off valve element 20 and the machine-shaping in the lump of fluorinfused nozzle 50, to improve production efficiency.
The present invention also proposes a kind of air conditioner, and the air conditioner includes stop valve, and the concrete structure of the stop valve is with reference to above-mentioned
Embodiment, because this air conditioner employs whole technical schemes of above-mentioned all embodiments, therefore equally has above-described embodiment
All beneficial effects for being brought of technical scheme, this is no longer going to repeat them.
It should be noted that the technical scheme of each embodiment of the present invention can be combined with each other, but must be with this
The technical staff in field can be implemented as basis, will be understood that when the combination appearance of technical scheme is conflicting or can not realize
The combination of this technical scheme is not present, also not within the protection domain of application claims.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize
The equivalent structure transformation that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
