CN2223404Y - Quickfit reducing element - Google Patents

Abstract

The utility model discloses the structure of a quickfit reducing element. The quickfit reducing element is mainly composed of a reducer pipe of which the end port is provided with an outer screw, a taper short casing pipe, and a taper locknut. An inner screw which is fitted with the outer screw on the end port of the reducer pipe is arranged at the end port of the taper locknut. The taper short casing pipe is put in the taper locknut. The utility model has advantages that the quickfit reducing element can quickly and reliably connect pipelines under the condition that the pipelines which are connected are not treated; the quickfit reducing element is especially adapted to be used when old pipelines are repaired.

Description

The fast-assembling reducing element

The utility model relates to a kind of structure of fast-assembling reducing element.

Reducing element is one of main link of various pipes.Existing reducing element is exactly a female reducer pipe of two-port.During use, need be at the outside thread of the screw-internal thread fit on cover system and the above-mentioned reducer pipe port on the connected pipe.The main deficiency that prior art exists is: during use, need be to connected pipe demolition and cover system screw thread, and therefore, difficulty of construction is big, and the cycle is long; The dismounting pipe loss is big, is not suitable for the maintenance to old pipeline especially.

The purpose of this utility model provides a kind of fast-assembling reducing element, and it does not need connected pipe is carried out any processing, pipeline can be coupled together; Its easy construction, quick, reliable is used when being particularly suitable for old pipeline maintainance.

In order to achieve the above object, solution of the present utility model is: be added with outside thread outside the port of common reducer pipe, at the port of reducer pipe taper short sleeve and taper locknut be housed.The internal thread that cooperates with outside thread on the reducer pipe port is arranged in the large port of taper locknut; The taper short sleeve places in the taper locknut.

Owing to adopted technique scheme, major advantage of the present utility model is: it can not carry out under the condition of any processing connected pipe, convenient, fast, connecting tube reliably; Use when being particularly suitable for old pipeline maintenance.

The drawing of the utility model accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.In an embodiment, be 1 reducer pipe, 2 are the taper short sleeve, and 3 are the taper locknut, and 4 for being connected pipeline.

In an embodiment, the external cross section of taper locknut is a regular hexagon; The external cross section of reducer pipe is a regular hexagon.The material of taper short sleeve can be metallic material, also can be nonmetallic material, as rubber or plastics etc.

Claims (3)

1, a kind of fast-assembling reducing element has a reducer pipe, it is characterized in that: it also includes taper short sleeve and the taper locknut that cooperates with reducer pipe; There is outside thread the port of reducer pipe, and there is the internal thread that cooperates with the outside thread of reducer pipe port at the large port place of taper locknut, and the taper short sleeve places in the taper locknut.

2, according to the described fast-assembling reducing element of claim 1, it is characterized in that: the external cross section of taper locknut is a regular hexagon.

3, according to claim 1 or 2 described fast-assembling reducing elements, it is characterized in that: the external cross section of reducer pipe is a regular hexagon.
