Abstract
The utility model relates to a backing-stop non-reverse connector arranged between gas meters and pipelines. The utility model is composed of a gas inlet joint, a gas outlet joint and a corrugated pipe, wherein, the exteriors of the gas inlet joint and the gas outlet joint are matched with backing-stop nuts. The insides of the backing-stop nuts are provided with hollow grooves. The interiors of the hollow grooves are provided with backing-stop spring sheets. The screw-thread surfaces of the outsides of the gas inlet joint and the gas outlet joint are provided with thorn grooves. When the backing-stop nut is screwed into a backing-stop gas outlet pipe joint, the backing-stop spring sheet works, the backing-stop nut is screwed from the single direction, and the motion direction is not reverse until the backing-stop nut is tightly screwed. The utility model effectively prevents users from automatically dismounting connection structures of household gas meters and transportation pipelines, and thus the gas safety is improved.
Description
Technical field:
The utility model relates to a kind of assembling pipe joint, relates in particular to the connection set of a kind of gas meter and pipeline, particularly a kind of irreversible connection set of retaining that is used between gas meter and the pipeline.
Background technique:
In the prior art, domestic gas meter and the Placement of transmission and distribution pipeline are that the turnover gas joint of gas meter is connected with bellows by nut, seal ring.The shortcoming that this Placement exists is: the user can dismantle easily at finishing or in using, thereby brings many potential safety hazards.
Summary of the invention:
Technical problem to be solved in the utility model is: because in the prior art, domestic gas meter and the Placement of transmission and distribution pipeline are that the turnover gas joint of gas meter is connected with bellows by nut, seal ring.This Placement makes the user can dismantle at an easy rate at finishing or in using, thereby gas safe is brought many hidden danger.
The purpose of this utility model is to provide a kind of irreversible connection set of retaining that is used between gas meter and the pipeline, and described connection set can prevent that the user from dismantling the linkage structure of domestic gas meter and transmission and distribution pipeline voluntarily, thereby improves gas safe.
The utility model is to achieve the above object and the technological scheme that the problems referred to above adopted that solves in the prior art provides a kind of irreversible connection set of retaining that is used between gas meter and the pipeline, the described this irreversible connection set of retaining that is used between gas meter and the pipeline is made of turnover gas joint and bellows, it is characterized in that, described turnover gas joint outside is equipped with the retaining nut, described retaining nut top and described bellows are connected, between described retaining nut and described bellows and described turnover gas joint, be provided with seal ring, described retaining nut inboard is provided with dead slot, be provided with retaining reed in described dead slot, the outside screw surface of described turnover gas joint is provided with the sour jujube groove.Concrete, described retaining nut inboard is provided with at least two dead slots, and the outside screw surface of described turnover gas joint is provided with at least four sour jujube grooves.
The utility model compared with the prior art effect is positive and tangible, the utility model restriction structurally, make when gas meter is installed it to be unidirectional rotation and irreversible, thereby prevented that effectively the user from dismantling the linkage structure of domestic gas meter and transmission and distribution pipeline voluntarily, improved gas safe, practical effect is obvious.
The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings:
Fig. 1 is the structural representation that the utility model is used for a preferred embodiment of the irreversible connection set of retaining between gas meter and the pipeline.
Fig. 2 is the cross section structure schematic representation of the turnover gas joint of the utility model preferred embodiment being used for the irreversible connection set of retaining between gas meter and the pipeline.
Embodiment:
As depicted in figs. 1 and 2, the irreversible connection set of retaining that the utility model is used between gas meter and the pipeline is made of turnover gas joint 5 and bellows 1, it is characterized in that described turnover gas joint 5 outsides are equipped with retaining nut 2, described retaining nut 2 tops and described bellows 1 are connected, between described retaining nut 2 and described bellows 1 and described turnover gas joint 5, be provided with seal ring 3, described retaining nut 2 inboards are provided with dead slot 7, be provided with retaining reed 4 in described dead slot 7, the outside screw surface of described turnover gas joint 5 is provided with sour jujube groove 8.Concrete, described retaining nut 2 inboards are provided with at least two dead slots 7, and the outside screw surface of described turnover gas joint 5 is provided with at least four sour jujube grooves 8, and during use, described turnover gas joint 5 one ends are fixed on the watchcase 6 of gas meter.
Working principle of the present utility model is described below: when retaining nut 2 screwed in retaining steam outlet pipe joint 5, retaining reed 4 was started working, and made retaining nut 2 to screw in by single direction, and until screwing, moving direction is irreversible; If oppositely screw out, can damage retaining nut 2, thereby prevent that effectively the user from dismantling the linkage structure of domestic gas meter and transmission and distribution pipeline voluntarily, improved gas safe.
Claims (3)
1, a kind of irreversible connection set of retaining that is used between gas meter and the pipeline, constitute by turnover gas joint and bellows, it is characterized in that: described turnover gas joint outside is equipped with the retaining nut, described retaining nut top and described bellows are connected, between described retaining nut and described bellows and described turnover gas joint, be provided with seal ring, described retaining nut inboard is provided with dead slot, be provided with retaining reed in described dead slot, the outside screw surface of described turnover gas joint is provided with the sour jujube groove.
