Description
Technical field
The utility model relates to the connection structures of a kind of burnt gas valve and pipeline, belong to pipe gas equipment technical field.
Background technique
It is well known that pipe joint is essential component in gas pipeline process of deployment.Burnt gas valve and pipeline are logical
It is connected and sealed frequently with simultaneously cap, anti-extraction ring and sealing ring, but existing anti-extraction ring mostly uses ring made of metal,
It is easy craze and transfiguration in use process, leads to the connection structure of existing burnt gas valve and pipeline there are connection reliability and is not high
Defect is easy in use or when surface subsidence causes burnt gas valve and gas pipeline to be detached from.
Summary of the invention
The purpose of this utility model is that: propose that a kind of burnt gas valve and pipeline connection reliability are high, are not easy to be mutually disengaged
Connection structure.
In order to solve the above-mentioned technical problem, the utility model proposes technical solution be: a kind of burnt gas valve and pipeline
Connection structure, including anti-extraction ring, sealing ring and simultaneously cap, described sealing ring one end are the ring-shaped rubber part of cone structure, described anti-
Pulling out ring is the annulus being made of hard material, and at least three steel balls, the anti-extraction ring and sealing ring are equipped at intervals on the annulus
Inside all have the inner hole worn for pipeline；Described and cap inner hole is divided into two sections, and one section is equipped with and matches with the external screw thread of valve
Internal screw thread, the other end is the bellmouth gradually expanded outwardly, and the anti-extraction ring is acted against on sealing ring and is placed in and cap
In bellmouth.
When the utility model is used, simultaneously cap plays the role of to seal between burnt gas valve and gas pipeline, resistance to plucking is enclosed
To the effect of fixed gas pipeline and burnt gas valve, while burnt gas valve and combustion gas caused by can preventing because of reasons such as surface subsidence
The effect that pipeline is detached from.The trend that gas pipeline is detached from burnt gas valve moves up for pipeline, and pipeline moves up first
Overcome steel ball insertion pipe gas and resistance that simultaneously cap generates, meanwhile, gas pipeline moves up, i.e. drive steel ball is to moving up
It is dynamic, and in this structure, steel ball is more upward, and the space between pipeline and simultaneously cap is smaller, and steel ball is embedded in gas pipeline and the simultaneously resistance between cap
Power is bigger, and therefore, burnt gas valve and pipeline connection reliability are high in the utility model, are not easy to be mutually disengaged.
In order to protect sealing ring, the further improvement of above-mentioned technical proposal is: being equipped between the anti-extraction ring and sealing ring
Washer.
In order to improve the intensity of annulus, the further improvement of above-mentioned technical proposal is made of: the annulus is using metal.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the enlarged diagram in Fig. 1.
Appended drawing reference: 1- anti-extraction ring, 2- washer, 3- sealing ring, 4- and cap, 5- burnt gas valve, 6- fill glue, 7- fuel gas conduit
Road, 8- threeway, 9- steel ball.
Specific embodiment
Embodiment
As shown in Figure 1, the burnt gas valve of the present embodiment and the connection structure of pipeline, by anti-extraction ring 1, sealing ring 3 and simultaneously cap 4
It constitutes.Wherein anti-extraction ring 1 is an annulus, is uniformly distributed more steel balls on the annulus, sealing ring 3 is the ring that one end is cone structure
Shape rubber parts, described and cap 4 inner hole are divided into two sections, and one section 4 is equipped with the matched internal screw thread of external screw thread with burnt gas valve 5, separately
One end is the bellmouth gradually expanded outwardly, i.e., it is internal screw thread that simultaneously cap 4, which is one end, and the other end is the structure with outer inclined-plane.
The anti-extraction ring 1 is acted against on sealing ring 3 and is placed in the simultaneously bellmouth of cap 4, this is the prior art, such as Fig. 1
It is shown, it repeats no more.In addition, the junction of described and cap 4 and gas pipeline 7, burnt gas valve 5 is provided with filling glue 6.
In order to protect sealing ring 3, washer 2 is equipped between the anti-extraction ring 1 and sealing ring 3.
Preferably, the annulus is made of metal.The steel ball 9 can be fixed on annulus, can also be as on bearing
Steel ball insertion retainer it is the same, steel ball 9 is embedded in the hole being arranged on annulus.
The working principle of the present embodiment is as follows:
When gas pipeline installation, according to sequential analysis from the bottom up, by burnt gas valve 5 and lower part gas pipeline 7
After being installed by screw thread, rotation is sent and the screw thread between cap 4 and burnt gas valve 5, and the gas pipeline 7 on top is inserted into gas valve
In door 5, threeway and the transverse direction gas pipeline at top are then connected, at this point, simultaneously the screw thread between cap 4 and burnt gas valve 5 is to screw, on
The gas pipeline in portion be free to rotate and move up and down, that is to say, that and top fuel gas conduit can match with 8 rotating dress of threeway,
After top gas pipeline and threeway 8 screw (i.e. pipeline construction terminates), simultaneously cap 4 is rotated, keeps it mobile to burnt gas valve 5, simultaneously
Drive anti-extraction ring 1, washer 2 and sealing ring 3 mobile to burnt gas valve 5.In this process, the cone structure of 3 one end of sealing ring
It is bonded, compresses with the inclined-plane of 5 one end of burnt gas valve, until sealing, continues to screw simultaneously cap 4, increase the outer inclined-plane and resistance to plucking of simultaneously cap 4
Pressing force on ring 1 between steel ball, until in steel ball insertion and cap and gas pipeline.
In the present embodiment, and cap 3 plays the role of to seal between burnt gas valve 5 and gas pipeline 7, and resistance to plucking circle 1 plays solid
Determine the effect of gas pipeline 7 and burnt gas valve 5, while burnt gas valve 5 and combustion gas caused by can preventing because of reasons such as surface subsidence
The effect that pipeline 7 is detached from.The trend that gas pipeline 7 is detached from burnt gas valve 5 moves up for pipeline, and pipeline moves up,
The resistance for overcoming steel ball insertion pipe gas 7 and simultaneously cap 4 generates is first had to, meanwhile, gas pipeline moves up, i.e. drive steel ball
It moves up, and in this structure, steel ball is more upward, and the space between pipeline and simultaneously cap 4 is smaller, and steel ball is embedded in gas pipeline 7 and simultaneously
Resistance between cap 4 is bigger, and therefore, burnt gas valve and pipeline connection reliability are high in the present embodiment, are not easy to be mutually disengaged.
The specific technical solution that the utility model is not limited to the above embodiment, in addition to the implementation, the utility model
There can also be other embodiments.All technical solutions formed using equivalent substitution or equivalent transformation, all fall within the utility model
It is required that protection scope.
