Description
Technical field
The utility model relates to a kind of three-way connection for fuel gas conduit more particularly to a kind of three-way connections of fuel gas conduit.
Background technique
Three-way connection, also known as tee tube, i.e., there are three openning, import two outlets or two import one outlets,
There are isometrical nozzle and reducing nozzle, be used for three identical or different pipeline junctions, its main function is to change flow direction.
Currently, being mainly metal material for the three-way connection in fuel gas conduit, general structure includes being responsible for and being responsible for one
Side perpendicular to supervisor and with supervisor be connected to setting branch pipe, supervisor export direction and branch outlet direction cross corner be arranged
Round valve block is arranged on valve for valve, and valve block is the structure sealed against each other with lumen wall in lumen closed state.However do not have
The structure that detection hole is opened up on three-way connection, the air-leakage test common practice in detection gas pipeline is to examine pressure
The both ends end that measurement equipment is mounted on pipeline measures, and such as tests out leakage or abnormal conditions, is only capable of judging that whole segment pipe is deposited
The method for leaking, and repairing is usually to replace whole segment pipe, and the pipeline for not occurring leaking also while replacing,
It is high to lead to replacement cost, while causing the waste of resource.
Utility model content
In view of the above-mentioned problems, technical solution provided by the utility model is a kind of three-way connection of fuel gas conduit.
Specific technical solution is accomplished by a kind of three-way connection of fuel gas conduit, and joint body gas intersection outer surface is set
Have a cylindrical protrusions and nut, the height of projection is 2~3mm, and the convex outer surface is equipped with screw thread, the internal screw thread of nut with
Convex outer surface screw thread matches, it is described protrusion be embedded structure, the elastic internal bladder of metal shell and internal layer including outer layer,
The liner includes metal clip and resilient sleeve, the clip lock ring in resilient sleeve, be provided with 0.2 in the resilient sleeve~
The detection hole of 0.8mm.
Preferably, the 21 material selection brass of shell.
Preferably, the 222 material selection rubber of resilient sleeve.
The three-way connection of the fuel gas conduit of the utility model is provided with gaseous-pressure detection hole, and it is close to can detect gas pipeline middle section
Feng Xing reduces leak detection range, while saving replacement cost, and resource application is more reasonable.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment.
Fig. 2 is the lobed interior enlarged fragmentary perspective structural schematic diagram of the utility model embodiment.
The label in accompanying drawing is: 1- joint body, 2- protrusion, 3- nut, 21- shell, 22- liner, 221- clip, 222-
Resilient sleeve, 223- detection hole.
Specific embodiment
The preferred technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1~2: a kind of three-way connection of fuel gas conduit, 1 gas intersection outer surface of joint body are set
Have a cylindrical protrusions 2 and nut 3, raised 2 height is 2~3mm, and raised 2 outer surface is equipped with screw thread, nut 3 it is interior
Screw thread matches with raised 2 outer surface threads, and described raised 2 be embedded structure, metal shell 21 and internal layer including outer layer
Elastic internal bladder 22, the liner 22 include metal clip 221 and resilient sleeve 222,221 lock ring of clip is in resilient sleeve 222
On, the detection hole 223 of 0.2~0.8mm is provided in the resilient sleeve 222.
Preferably, the 21 material selection brass of shell.
Preferably, the 222 material selection rubber of resilient sleeve.
It is further preferred that 223 diameter of detection hole is 0.6mm.
It is further preferred that raised 2 height is 2.5mm.
In specific implementation, when needing to detect, the nut 3 on shell 221 is unscrewed, the interface insertion of pressure checking device is connect
In detection hole 223 on head ontology 1, wherein the interface of pressure checking device should be equal or slightly larger than detection bore dia 223, choosing
With the interface of 0.6mm outer diameter, interface passes through resilient sleeve and enters realization detection pressure inside joint body 1；After having detected, by interface
It extracts, then nut 3 is tightened in 21 outer surface of shell, nut 3 plays the role of dust seal, meanwhile, no matter in detection device
Interface insertion or withdrawal process in, collapsed seal under the action of clip 221 of resilient sleeve 222 plays sealing effect, gas
It will not leak.
Preferred embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these are all
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
