Abstract
The utility model relates to a nozzle seal structure of a gas metal tube. The nozzle seal structure comprises the gas metal tube (2) and sealing members (1). The sealing members (1) are fixedly installed to all nozzles of the gas metal tube (2) and seal the nozzles. The sealing members (1) are of a conical disc shape. The outer sidewalls of the circumferences of the sealing members or the hollow inner side walls of the sealing members are conical surfaces connected with the nozzle side walls of the gas metal tube (2) in an interference fit mode. By the adoption of a cold machining technology, the sealing members are connected with the gas metal tube through interference fit between the conical surfaces and flat and straight surfaces, in this way, various hazards of a welding technology are avoided, and product quality is guaranteed.
Description
Technical field
The utility model relates to pipeline sealing structure field, particularly relates to a kind of ferrule structure of gas metal pipe.
Background technique
Gas metal pipe has had application widely in every field, wherein gas metal pipe is the combustion gas parts that all will use in current family or diet shop, there is combustion gas interface the centre that its structure mostly is gas metal pipe, on the pipe shaft of gas metal pipe, there are multiple air outlet holes, but its two ends must seal completely, can not leak gas.
The sealed at both ends mostly of current gas metal pipe are to adopt Sealing to be welded on mouth of pipe place, realize sealing, after having welded, more whole gas metal pipe carried out to electroplating technology, make the outer surface of gas metal pipe antirust, but due to plating time, two ends seal, electroplate liquid flow in pipe and is difficult to pour out from air outlet hole, electroplate liquid is serious pollutant, can not sell together with product, this difficult problem is difficult to solve always, will affect the outward appearance of gas metal pipe and welding slag is stayed to outer surface if welded after plating completes again.
In addition, use welding procedure can produce high temperature and high light, and produce toxic gas, affect direct labor's health, workman's welding technique is required also very high, weld not in place will causing to leak gas, product is also scrapped thereupon.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of ferrule structure of gas metal pipe, adopt cold machining process, utilize interference fit connection sealing element and the gas metal pipe of the conical surface and flat face, avoided the various harm of welding procedure, more ensured the quality of product.
The utility model solves the technological scheme that its technical problem adopts: a kind of ferrule structure of gas metal pipe is provided, comprises gas metal pipe and Sealing, described Sealing is fixedly mounted on each mouth of pipe of gas metal pipe ferrule is lived;
In order Sealing to be connected under the condition not using welding procedure to sealing with gas metal pipe, described Sealing is circular cone dish type, the madial wall of its periphery wall or inner hollow out is conical surface, between the mouth of pipe sidewall of this conical surface and gas metal pipe for interference fit is connected, interference fit makes to be fixedly connected with between Sealing and gas metal pipe, because conical disc mouth has non-return effect, Sealing is beaten and form tension force after the mouth of pipe of gas metal pipe and block tube wall and just can not be pulled out, ensure sealability in use and the high resistance performance that comes off.
As a kind of preferred version of the present utility model, the upper-end surface hollow out of described Sealing, conical surface on its cylindrical side is small top and big bottom layout, this conical surface is connected with the mouth of pipe madial wall interference fit of gas metal pipe, seal embed wholly is to the mouth of pipe inner side of gas metal pipe, inner hollow out can be saved material, and the sidewall of Sealing is easily out of shape in beaing the mouth of pipe, in tilted conical surface extruding leakproof intercept face, and oblique cone outer rim otch has brute force and prevents the anti-high pressure characteristics of reverse disengaging effect.
Supplement as another kind of the present utility model, the thickness of described Sealing is less than the wall thickness of gas metal pipe, prevents that Sealing from making mouth of pipe distortion by broken the structure of mouth of pipe sidewall ring in being pressed into the mouth of pipe.
Supplement as another kind of the present utility model, described sealing member material is for possessing flexible metallic material or composite material, described gas metal pipe is that metallic material is made, and the interference fit part of Sealing and gas metal pipe can be out of shape simultaneously, has ensured the combination force of interference fit.
Further, the diameter of the little head end of the conical surface of described Sealing is less than the diameter of bore of gas metal pipe, the diameter of its stub end is greater than the diameter of bore of gas metal pipe, while having ensured installation, microcephaly holds and can be introduced in the mouth of pipe, be conducive to beat hand-hole, whole Sealing submerges in the mouth of pipe, between its upper-end surface and the end face of the mouth of pipe, leaves a segment distance.
beneficial effect
The utility model adopts cold machining process, utilize interference fit connection sealing element and the gas metal pipe of the conical surface and flat face, can gas metal pipe electroplate after by it, inner electroplate liquid is sealing after pouring out, avoid using welding procedure, make the beautiful shape of gas metal pipe, good airproof performance, in the process of producing, can not produce harmful gas and high temperature, clean environment firendly, and ensure direct labor's safety, also can be and electroplates pipe or stainless steel gas metal pipe and impose direct riveting and enter sealing.

Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is the structure sectional view of a kind of preferred version of the present utility model;
Fig. 3 is the enlarged view of Sealing described in the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Figure 1-3, mode of execution of the present utility model relates to a kind of ferrule structure of gas metal pipe, comprises gas metal pipe 2 and Sealing 1, and described Sealing 1 is fixedly mounted on each mouth of pipe of gas metal pipe 2 ferrule is lived,
Described Sealing 1 is circular cone dish type, and the madial wall of its periphery wall or inner hollow out is conical surface, between this conical surface and the mouth of pipe sidewall of gas metal pipe 2 for interference fit is connected.
Described Sealing 1 material is for possessing flexible metallic material or composite material, and described gas metal pipe 2 is made for metallic material, and the thickness of described Sealing 1 is less than the wall thickness of gas metal pipe 2.
Embodiment 1
