Abstract
The utility model discloses a kind of core machine gas hose, it comprises gas hose, it is characterized in that, one end of described gas hose is provided with movable joint, described movable joint can around described gas hose axial-rotation, one end of described gas hose is provided with permanent joint, and the relatively described gas hose of described movable joint is fixed.This practical core machine gas hose manufacture is simple, with low cost, it is reliable etc. to seal.Be applicable to the link of core machine gas pipeline, equipment failure and security incident can be lowered, widened the versatility of gas hose; And can solve the technical barrier of core machine gas hose poor sealing.
Description
Technical field
The utility model relates to a kind of core machine gas hose, is a kind of equipment combustion gas gas circuit connecting device.Be applicable to hot core machine fuel gas pipeline connect, the gas hose being particularly useful for the hot core machine of type Z957 type connects.
Background technique
In current core machine gas pipe connected system, the clamping joint form that adopts connects more, the advantage that clamping joint connects, do not need dedicated custom core machine natural gas tube, according to the size of caliber, the pipeline of an entire volume can be bought to market, then according to the demand cut processing voluntarily at scene, draw materials conveniently.But clamping joint is connected with very large shortcoming, clamping joint position easily loosens gas leakage and even comes off, and affects device fabrication, also easily causes security incident simultaneously.How to keep on the basis of existing advantage, the safety reliability improving core machine gas pipe connected system needs a difficult problem for solution at present badly.
Model utility content
The purpose of this utility model is to provide a kind of core machine gas hose, connects the problems such as not firm, easy leakage to solve existing flexible pipe.For realizing this purpose, the technological scheme that the utility model is taked is:
A kind of core machine gas hose, it comprises gas hose, it is characterized in that, one end of described gas hose is provided with movable joint, described movable joint can around described gas hose axial-rotation, one end of described gas hose is provided with permanent joint, and the relatively described gas hose of described movable joint is fixed.
Further, described gas hose is pressure hose.
Further, described movable joint is actively socketed on the inipple on described gas hose.
Further, described movable joint inwall is provided with the internal thread be threaded with outside connecting head.
Further, described permanent joint inwall is provided with the internal thread be threaded with outside connecting head.
Further, the side near described gas hose in the inwall of described movable joint and permanent joint is provided with intilted conical seal (contact) face.
Core machine gas hose of the present utility model has the advantage of existing flexible pipe concurrently, enhances the sealing that end face connects simultaneously, and application widely.The advantages such as it has low cost of manufacture, long service life, and sealing effect is excellent.This oil pipe beautiful shape, manufacture simple, with low cost, seal reliable, easy to maintenance, be arranged to be threaded at pipeline two ends simultaneously, end firm and reliable connection, pipe joint is designed to taper, and while fastening end face, pipe joint is from being about to its sealing.The utility model is applicable to the gas pipeline link of hot core core machine, effectively can reduce equipment failure and reduce security incident.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of the utility model core machine gas hose;
Fig. 2 is the structural representation of the utility model core machine gas hose;
Fig. 3 is the sectional structure schematic diagram of rotatable connector;
Fig. 4 is the sectional structure schematic diagram of not rotatable connector.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figures 1 to 4, the structure of core machine gas hose of the present utility model is: comprise gas hose 12, and the supervisor of gas hose 12 adopts steel wire braiding to add rubber hose, can bear certain pressure during use.Not rotatable connector form is taked in one end of gas hose 12, namely arranges the non-rotatable permanent joint 9 of a relative gas hose 12, thus ensures that gas hose 12 can maintain static upon connection.The other end of gas hose 12 takes swivel form, namely arranges the rotating movable joint 20 of a relative gas hose 12, is flexibly connected 20 and can eliminates the torsion that the gas hose 12 that produces when fastening produces in fastener cycle.Movable joint 20, permanent joint 9 are connected with equipment connection head 5, equipment connection head 15 respectively.
The utility model adopts single piece, and it is convenient to change, and is provided with internal thread 11,14 to be connected with equipment connection head in the inwall of movable joint 20, permanent joint 9, easy to connect and firm.The inner wall of movable joint 20, permanent joint 9 is all designed to taper, thus the sealing surface 18 formed when being connected with equipment connection head 5, equipment connection head 15 and sealing surface 17, to play self-sealing, do not need additional sealing.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
Claims (6)
1. a core machine gas hose, it comprises gas hose, it is characterized in that, one end of described gas hose is provided with movable joint, described movable joint can around described gas hose axial-rotation, one end of described gas hose is provided with permanent joint, and the relatively described gas hose of described permanent joint is fixed.
2. core machine gas hose according to claim 1, is characterized in that, described gas hose is pressure hose.
