Abstract

The utility model relates a double-wall bellows tube material, in particular to the double-wall bellows tube material facilitating construction connection. The double-wall bellows tube material comprises a tube head, a tube body and a tube tail. The tube head and the tube tail are respectively provided with a bearing opening and an insertion opening corresponding to the bearing opening. The double-wall bellows tube material is divided into two classes of 8 kilonewtons per square meters and 4 kilonewtons per square meters according to ring rigidity of the tube body. The bearing openings and the insertion openings of the tube material of the two classes are the bearing openings and insertion openings which are of a same class and prepared through moulds of the same class. No matter whether the tube material is 8 kilonewtons per square meter or 4 kilonewtons per square meter, on the condition of the same tube diameter, the bearing openings and the insertion openings are the same and can be inserted with each other in a sleeved mode. Moreover, rubber sealing ring specifications are also the same, so interchangeability of the tube material is improved and construction is convenient to carry out.

Description

A kind of double-wall corrugated pipe tubing of being convenient to construct and connecting

Technical field

The utility model relates to a kind of double-wall corrugated pipe tubing, relates in particular to a kind of double-wall corrugated pipe tubing of being convenient to construct and connecting.

Background technique

Double-wall corrugated pipe tubing is a kind of novel tube with ring structure outer wall and smooth internal walls; Very ripe on production technology and operation technique at present; And because the cost of its excellent performance and relatively economical has obtained great promotion and application.Double-wall corrugated pipe tubing is divided into two types of 8,000 Ns of/square metre tubing and 4,000 Ns of/square metre tubing by its ring stiffness; The width of these two types of tubing ring structure outer walls is different with thickness; The construction of double-wall corrugated pipe tubing connects, and need its bellmouth and socket be docked, and it is provided with rubber seal between the two; Because the bellmouth of different ring stiffness tubing and socket are different; Make that also rubber seal has different specifications, the interchangeability of tubing and the interchangeability of rubber seal are poor, and it is not convenient to construct.

The model utility content

The utility model technical problem to be solved is, overcomes the deficiency that exists in the existing technology, and a kind of double-wall corrugated pipe tubing of constructing and connecting be convenient to is provided.

The utility model is to be achieved through following technological scheme:

A kind of double-wall corrugated pipe tubing of being convenient to construct and connecting; Comprise tube head, pipe shaft and pipe tail; Said tube head and pipe tail are respectively equipped with bellmouth and reach and the corresponding socket of bellmouth; Said double-wall corrugated pipe tubing is divided into 8,000 Ns/square metre and 4,000 Ns/square metre two types by the ring stiffness of pipe shaft, and the bellmouth of said two types of tubing and socket are for using the of a sort bellmouth and the socket of same type of mould preparation.

The beneficial effect of the utility model is:

Because the bellmouth of two types of tubing and socket are for using the of a sort bellmouth and the socket of same type of mould preparation; No matter be that 8,000 Ns of/square metre tubing of going back 4,000 Ns/square metre are under the identical situation of caliber promptly; Bellmouth and socket are identical, and the specification of facies suite insert, and rubber seal mutually is also identical; Improved the interchangeability of tubing, made that construction is convenient.

Description of drawings

Fig. 1 is the main TV structure schematic representation of the utility model.

Among the figure: 1. bellmouth, 2. pipe shaft, 3. socket.

Embodiment

For the technician who makes the present technique field understands the technological scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and most preferred embodiment.

As shown in Figure 1; The utility model comprises tube head, pipe shaft and pipe tail; Said tube head and pipe tail are respectively equipped with bellmouth and reach and the corresponding socket of bellmouth; Said double-wall corrugated pipe tubing is divided into 8,000 Ns/square metre and 4,000 Ns/square metre two types by the ring stiffness of pipe shaft, and the bellmouth of said two types of tubing and socket are for using the of a sort bellmouth and the socket of same type of mould preparation.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.

Claims

1. double-wall corrugated pipe tubing of being convenient to construct and connecting; Comprise tube head, pipe shaft and pipe tail; Said tube head and pipe tail are respectively equipped with bellmouth and reach and the corresponding socket of bellmouth; Said double-wall corrugated pipe tubing is divided into 8,000 Ns/square metre and 4,000 Ns/square metre two types by the ring stiffness of pipe shaft, it is characterized in that, the bellmouth of said two types of tubing and socket are for using the of a sort bellmouth and the socket of same type of mould preparation.
