Description
Technical field
The utility model relates to shut-off valve, the connection structure of especially a kind of shut-off valve and capillary.
Background technique
It is well known that existing shut-off valve is both provided with a connecting tube that can be connected with capillary, due to the two knot
The reason of structure, the diameter of the diameter of connecting tube one end coupled much larger than the capillary.
Referring to Fig.1, in order to enable the two can connect together, pacify usually at the connecting tube 100 ' of shut-off valve 10 '
Transitional connection pipe 30 ' equipped with a diameter gradually from large to small then passes through the transitional connection pipe 30 ' and 20 ' phase of capillary again
Connection is later again welded together the connecting tube 100 ' of shut-off valve 10 ' with transitional connection pipe 30 ' by the way of welding, together
When also transitional connection pipe 30 ' and capillary 20 ' to be welded together by the way of welding.
In the process, it both needs to increase a transitional connection pipe 30 ', while needing respectively by the connection of shut-off valve 10 '
Pipe 100 ' welds together with transitional connection pipe 30 ' and welds together transitional connection pipe 30 ' and capillary 20 ', both significantly
Production cost is increased, and needs to be welded twice, it is time-consuming and laborious, reduce the competitiveness of society of enterprise.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of structure is simple, production can both be reduced
Cost, while the connection structure being connected again convenient for shut-off valve with capillary.
The utility model be solve its technical problem and the technical solution adopted is that:
A kind of connection structure of shut-off valve and capillary, including a shut-off valve and a capillary, wherein on the shut-off valve
It is provided with the connecting tube being connected with the capillary, is provided with one on one end that the connecting tube is connected with the capillary
Reducer, one end that the reducer is connected with the shut-off valve is major diameter section, and the reducer is connected with the capillary
The one end connect is path section, and the diameter of the major diameter section is greater than the diameter of the path section；Wherein, the reducer with described section
Only valve is an integral structure.
As an improvement of the above technical solution, the reducer is that the free end of the connecting tube is handled through necking.
As a further improvement of the above technical scheme, when the reducer is connected with the capillary, the capillary
One end of pipe is inserted into the path section, and is interference fit between the path section and the capillary for being inserted into its inside.
In the present invention, the reducer is fixed and welded together with the capillary.
The beneficial effects of the utility model are: since the utility model is by the way that one end of the connecting tube of shut-off valve to be arranged to
Reducer is connected by the reducer with capillary, and traditional connecting tube installation transition connection needed in shut-off valve has been abandoned
Pipe, the connection structure being then connected again by the transitional connection pipe with capillary is simple and convenient, can both reduce and be produced into
This, and when welding, it also only needs by reducer together with the capillary weld, process is simple, and can save
About wlding further decreases production cost.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the connection structure of traditional shut-off valve and capillary；
Fig. 2 is the structural schematic diagram of one preferred embodiment of the utility model；
Fig. 3 is the partial structurtes decomposition diagram of one preferred embodiment of the utility model.
Specific embodiment
Referring to Fig. 2 and Fig. 3, a kind of connection structure of shut-off valve and capillary, including a shut-off valve 10 and a capillary 20,
Wherein, be provided with the connecting tube 100 being connected with the capillary 20 on the shut-off valve 10, the connecting tube 100 with it is described
A reducer 11, one end that the reducer 11 is connected with the shut-off valve 10 are provided on one end that capillary 20 is connected
For major diameter section 110, and one end that the reducer 11 is connected with the capillary 20 is path section 111, the major diameter section 110
Diameter is greater than the diameter of the path section 111；Wherein, the reducer 11 is an integral structure with the shut-off valve 10.At this
In, as a preferred embodiment of the utility model, the reducer 11 is that the free end of the connecting tube 100 is handled through necking
It forms.The i.e. described reducer 11 is that the free end drawn of the connecting tube 100 shrinks and formed.
Since the utility model is by being arranged to reducer 11 for one end of the connecting tube 100 of shut-off valve 10, pass through the change
Diameter section 11 is connected with capillary 20, has abandoned traditional installation transitional connection pipe of connecting tube 100 needed in shut-off valve 10, then
The connection structure being connected again by the transitional connection pipe with capillary 20, it is simple and convenient, production cost can be both reduced, and
When welding, also only need to weld together reducer 11 and the capillary 20, process is simple, and can save weldering
Material further decreases production cost.
Herein, it is leaked between reducer pipe 11 and tubule pipe 20 in order to prevent, it is preferable that the reducer 11 and the hair
When tubule 20 is connected, one end of the capillary 20 is inserted into the path section 111, and the path section 111 and is inserted into it
It is interference fit between the capillary 20 in portion.By will be set between the capillary 20 inside path section 111 and insertion path section 111
It is set to interference fit, the gap of attachment force and reduction between the two between the two can be increased, prevent from leaking.It is further excellent
Choosing, the reducer 11 are fixed and welded together with the capillary 20, by welding, both can be by 11 He of reducer
The capillary 20 is fixed together, while can seal the gap between reducer 11 and capillary 20 again, effectively
Prevent the case where leaking between reducer 11 and capillary 20.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
