Abstract
The utility model relates to an inter-pipe connecting structure, particularly to an inter-gas- pipe connecting structure, which is composed of rubber gas pipes and joints. The utility model is characterized in that the joint is structured by a metal pipe body and a stainless steel inner pipe lined inside the metal pipe body; a connecting end of the rubber gas pipe is in a crimp connection between the metal pipe body and the stainless steel inner pipe; the outer end of the joint is provided with external thread; the joint is sleeved into the joint part of a connecting sleeve and is in a bolt connection with the internal thread of the joint part through the external thread. The utility model is mainly to solve the technical problem that for the current gas pipe connecting structure, the joint part of the rubber gas pipe is so directly exposed in the air that the joint part is eroded and damaged. In addition, the utility model is simple in connection and easy in operation.
Description
Technical field
The utility model relates to the linkage structure between body, bindiny mechanism between especially a kind of gas pipe.
Background technique
As everyone knows, the rubber gas pipe is the main delivery line of output coal gas gas from gas main, still, because the problem of rubber gas pipe length and the problem that the position is set sometimes need several gas pipes are linked together.
Existing rubber gas conveying tube linkage structure is such, and it comprises the connecting head of a metallic material, and these connecting head two ends have the belled part of tapered shape respectively, also has the multi-turn non-slip nosing that ring-type is provided with on this belled part.During connection, only the rubber gas pipe need be set on the belled part of connecting head and get final product.But the linkage structure of this gas pipe but has following defective:
When 1, the rubber gas pipe is enclosed within on the connecting head, can be easy to cause body when connecting, to produce cracking phenomena like this linkage section spreading of rubber gas pipe.
2, the belled part of rubber gas pipe and connecting head exposes in atmosphere, in the time of long-term after owing to be subjected to the influence of water in air part, the rubber of connecting end is easy to produce the phenomenon of corrosion.So not only can loss gas conveying tube road, and be very easy to cause coal gas accident safe in utilization.
The model utility content
The purpose of this utility model is to provide bindiny mechanism between a kind of gas pipe, mainly solve in the existing gas pipe bindiny mechanism, the joint of rubber gas pipe directly exposes the technical problem that can cause the joint corrosion and damage in air, and simple when connecting, easy operating.
For solving the problems of the technologies described above, technological scheme of the present invention is:
Bindiny mechanism between a kind of gas pipe, it is made up of rubber gas pipe and connecting head; It is characterized in that: this connecting head by the metal body and in be lining in that pipe constitutes in the stainless steel in the metal tube body, the connecting end of this rubber gas pipe is crimped in metal body and the stainless steel between the pipe; This connecting head outer end has outside thread, and this connecting head is inserted in the joint of a connecting sleeve, and is spirally connected by the internal thread of outside thread and a junction.
Bindiny mechanism between described gas pipe is characterized in that: this connecting head outer end is a cone structure, has the corresponding joint with internal thread of shape and oil pipe taper joint end in this connecting sleeve.
Bindiny mechanism between described gas pipe is characterized in that: the joint top is equipped with torque shoulder in this connecting sleeve.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is crimped on the connecting end of rubber gas pipe in metal body and the stainless steel between the pipe, like this, the joint of rubber gas pipe is not vulnerable to the corrosion infringement, and pipe also can prevent the liquid corrosion rubber gas pipe that has in the coal gas in the stainless steel, has therefore improved the coal gas safety in utilization greatly.
2, the utility model is when carrying out the gas pipe connection, and only connecting head need be spirally connected in connecting sleeve gets final product, therefore, easy to operate.

Embodiment
See also Fig. 1, it is the structural representation of bindiny mechanism between a kind of gas pipe of the utility model.As shown in the figure: it is made up of rubber gas pipe 4 and connecting head.This connecting head by metal body 1 and in be lining in that pipe 2 constitutes in the stainless steel in the metal tube body, the connecting end of this rubber gas pipe 4 is crimped in metal body 1 and the stainless steel between the pipe 2; This connecting head outer end has outside thread 11, and this connecting head is inserted in the joint 31 of a connecting sleeve 3, and is spirally connected by the internal thread 33 of outside thread 11 with a junction 31.This connecting head outer end is a cone structure, has the corresponding joint 31 with internal thread 33 of shape and oil pipe taper joint end in this connecting sleeve 3.Joint 31 tops are equipped with torque shoulder 32 in this connecting sleeve 3.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model
