Abstract
The utility model discloses a lined stainless steel reducer pipe fitting which comprises a reducer galvanized pipe (1) and a stainless steel pipe (2). The stainless steel pipe (2) is nested in the reducer galvanized pipe (1), a small-end flange plate (3) and a large-end flange plate (4) are respectively formed at two ends of the reducer galvanized pipe (1), the stainless steel pipe (2) is provided with flanges (21), and the flanges (21) at two ends of the stainless steel pipe (2) are respectively abutted to the end surfaces of the small-end flange plate (3) and the large-end flange plate (4). The lined stainless steel reducer pipe fitting has the advantages that the lined stainless steel reducer pipe fitting is good in sealing performance when connected with lined stainless steel straight pipes, and is easy to construct and convenient to install.
Description
Technical field:
The utility model relates to the pipe fitting technical field, more specifically to a kind of inner liner stainless steel CONCENTRIC REDUCER pipe fitting.
Background technique:
As shown in Figure 1, existing inner liner stainless steel CONCENTRIC REDUCER pipe fitting is comprised of Stainless Steel Tube A2 Coating Steel Pipe A1 inner sleeve, forms anchor ear groove A11 on Coating Steel Pipe A1, and it links together by anchor ear groove A11 and anchor ear and straight tube.Its deficiency is: when it with in when being lined with stainless straight tube and being connected, sealability is not strong, construction simultaneously gets up also to be not easy.
The model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of inner liner stainless steel CONCENTRIC REDUCER pipe fitting is provided, when it is connected with the straight tube of inner liner stainless steel, and good seal performance, construction is easily, easy for installation simultaneously.
Technology solution of the present utility model is as follows:
Inner liner stainless steel CONCENTRIC REDUCER pipe fitting, comprise CONCENTRIC REDUCER galvanized pipe and Stainless Steel Tube, Stainless Steel Tube is enclosed within the CONCENTRIC REDUCER galvanized pipe, two ends of CONCENTRIC REDUCER galvanized pipe form respectively microcephaly's flange plate and major part method half dish, Stainless Steel Tube has flange, and the flange of Stainless Steel Tube two ends is pressed over respectively on the end face of microcephaly's flange plate and major part method half dish.
The beneficial effects of the utility model are:
When it is connected with the straight tube of inner liner stainless steel, good seal performance, construction is easily, easy for installation simultaneously.
The accompanying drawing explanation:
The structural representation that Fig. 1 is prior art;
Fig. 2 is structural representation of the present utility model;
The structural representation of Fig. 3 when to be the utility model link together with straight tube with flange plate and inner liner stainless steel.
In figure: 1, CONCENTRIC REDUCER galvanized pipe; 2, Stainless Steel Tube; 3, microcephaly's flange plate; 4, major part method half dish; 5, with the straight tube of flange plate and inner liner stainless steel.
Embodiment:
Embodiment: as shown in Figure 2, inner liner stainless steel CONCENTRIC REDUCER pipe fitting, comprise CONCENTRIC REDUCER galvanized pipe 1 and Stainless Steel Tube 2, Stainless Steel Tube 2 is enclosed within CONCENTRIC REDUCER galvanized pipe 1, two ends of CONCENTRIC REDUCER galvanized pipe 1 form respectively microcephaly's flange plate 3 and the major part method partly coils 4, Stainless Steel Tube 2 has flange 21, and the flange 21 of Stainless Steel Tube 2 two ends is pressed over respectively microcephaly's flange plate 3 and major part method and partly coils on 4 end face.
Working principle: the available technology adopting anchor ear connects CONCENTRIC REDUCER pipe fitting and straight tube, and the one, construction and installation bother, and the 2nd, after installation, the stainless steel flange of flange on the CONCENTRIC REDUCER pipe fitting that inside is lined with stainless straight tube is combined defective tightness.
As shown in Figure 3, the utility model adopts flange plate to be fixed together by flange plate by CONCENTRIC REDUCER pipe fitting and the straight tube 5 with flange plate and inner liner stainless steel, flange 21 on the utility model has just forced together tightly with the stainless flange on straight tube, connection sealing can be better like this, operates easier simultaneously.
Claims (1)
1. inner liner stainless steel CONCENTRIC REDUCER pipe fitting, comprise CONCENTRIC REDUCER galvanized pipe (1) and Stainless Steel Tube (2), Stainless Steel Tube (2) is enclosed within CONCENTRIC REDUCER galvanized pipe (1), it is characterized in that: two ends of CONCENTRIC REDUCER galvanized pipe (1) form respectively microcephaly's flange plate (3) and major part method half dish (4), Stainless Steel Tube (2) has flange (21), and the flange (21) of Stainless Steel Tube (2) two ends is pressed over respectively on the end face of microcephaly's flange plate (3) and major part method half dish (4).
