Sealing effectiveness in use, the problem of effectively improving oil leak cigarette, and rubber is cheap, is produced into beneficial to reduction
This, good economy performance.
Preferably, first connecting portion 2-1-1 includes the body being adapted to the line size of smoke exhaust pipe 1, when smoke exhaust pipe 1 is arranged
After on body, being fixedly connected for smoke exhaust pipe 1 and body is realized by fastener.
To ensure the connection effect of smoke exhaust pipe 1 and smoke exhaust pipe erection joint component 2, first connecting portion 2-1-1 is provided with and row
The body that the line size of smoke pipe 1 is adapted, in this way, during installation, smoke exhaust pipe 1 is first socketed in first connecting portion 2-1-1 pipe
After body, then by way of the fastener such as viscose glue or screw, realize both be fixedly connected.Using above-mentioned fixed form, structure
Simply, production and processing technology is simple, is easy to assembling and good fixing effect, will not fall off, prevent the leakage of oil smoke, specifically can basis
It is actually needed to select rational fixed form.
Wherein, viscose glue can be coated with any one in smoke exhaust pipe 1 and body, and then to realize that both fixed connects
Connect, suitable coating object can be specifically selected according to actual implementation condition.
Preferably, first connecting portion 2-1-1 includes the body being adapted to the line size of smoke exhaust pipe 1, and body is provided with outer spiral shell
Line, the bottom of smoke exhaust pipe 1 are provided with the internal thread coordinated with external screw thread.
Being fixedly connected for smoke exhaust pipe 1 and smoke exhaust pipe erection joint component 2 is realized by the way of viscose glue or screw except above-mentioned
Outside, can also be by the way of threaded connection, specifically, body is provided with external screw thread, and the bottom of smoke exhaust pipe 1 is provided with interior spiral shell
Line, installation is screwed mutually by internal thread and external screw thread, the installation of smoke exhaust pipe 1 and erection joint body 2-1 can be made and repaired more
It is convenient and reliable, to prevent the leakage of oil smoke.
In addition, need further, it is emphasized that smoke exhaust pipe 1 also can be by producer in advance by two with smoke exhaust pipe erection joint component 2
It is individual pre-fix after, then carry out complete machine production shipment.
As shown in Fig. 3 to Fig. 9, present invention also offers a kind of component of smoke exhaust pipe 1, including smoke exhaust pipe 1, check valve assembly 3
And smoke exhaust pipe erection joint component 2.The component of smoke exhaust pipe 1 that the application provides is because of the smoke exhaust pipe being provided with above-mentioned technical proposal
Erection joint component 2, thus with all technique effects in above-mentioned technical proposal, to avoid repeating, therefore repeat no more.
Specifically, check valve assembly 3 includes non-return valve body, and the upper end of non-return valve body is provided with check-valves outer ring 3-1, only
Valve outer ring 3-1 is returned to be used to be connected with second connecting portion 2-1-2 hypomere 2-1-2-2；Set on check-valves outer ring 3-1 end face
There are multiple holding section 3-1-1, holding section 3-1-1 to be used for the bulge loop 2-1-2-1 clampings with smoke exhaust pipe erection joint component 2.
In the present embodiment, check valve assembly 3 includes non-return valve body, and non-return valve body has check-valves outer ring 3-1, the
Two connecting portion 2-1-2 hypomere 2-1-2-2 is stretched into the 3-1 of check-valves outer ring, and is realized by holding section 3-1-1 and pacified with smoke exhaust pipe
The bulge loop 2-1-2-1 clampings of attaching head assembly 2；Now, O-ring seal 2-2 is located at hypomere 2-1-2-2 and bulge loop 2-1-2-1 and connected
Connect between the outer surface at place and check-valves outer ring 3-1 inwall, compensate for erection joint body 2-1 and check-valves outer ring 3-1 by
In fit-up gap caused by design tolerance, foozle, so solve smoke exhaust pipe erection joint component 2 and check valve assembly 3 it
Between oil smoke leakage the problems such as.
Preferably, holding section 3-1-1 is hasp, and multiple hasps are uniformly distributed circumferentially in check-valves outer ring 3-1 end face
On, and hasp can be fastened on bulge loop 2-1-2-1 end face.
In the present embodiment, check-valves outer ring 3-1 end face is provided with four hasps, and four hasps are with check-valves outer ring 3-
It is symmetricly set on centered on 1 center on check-valves outer ring 3-1 end face.Wherein, the inward flange of hasp is into non-return valve body
The distance of axis, the distance of outward flange less than bulge loop 2-1-2-1 to erection joint body 2-1 axis, in this way, hasp can
It is fastened on bulge loop 2-1-2-1 end face, and then realizes that smoke exhaust pipe erection joint component 2 docks with the reliable of check valve assembly 3.
Particularly, except it is above-mentioned realized by the way of hasp and bulge loop 2-1-2-1 clampings smoke exhaust pipe erection joint component 2 with
Outside the reliable docking of check valve assembly 3, the erection joint of smoke exhaust pipe 1 can be with check valve assembly 3 using rotation card, screw thread, screw, glue
Any connected mode installation in band, can specifically select suitable connected mode according to actual implementation condition.
