Abstract
A great reducing nipple relates to a reducing nipple applied to petrifaction ground and comprises a bowl-shaped pipe body. The upper end of a bowl-shaped pipe (2) is arranged as a small upper-end pipe orifice (1) and the lower end thereof is arranged as a big lower-end pipe orifice (3), and the diameter of the bowl-shaped pipe (2) gradually changes. By arranging an upper-end connection pipe orifice at the upper end of the bowl-shaped pipe body and a lower-end connection pipe orifice at the lower end of the bowl-shaped pipe body, the great reducing nipple meets the connection requirement of a great reducing pipeline. Therefore, the great reducing nipple is simple in structure, simple and easy for installation and convenient for use, saves labor hour and can satisfy the technical requirement of complicated pipelines in reducing.
Description
Technical field
The utility model relates to a kind of big reduction nipple that is applied to the petrochemical industry surface line, especially relates to a kind of big reduction nipple in the pipe transferring technology field of liquid, gas even solid particle.
Background technique
Pipe-line system be in the daily life and departments such as petrochemical industry, electric power, nuclear power, machinery in use very extensively, pipe fitting is the member of conveyance fluid.This hollow products is in the conveyance fluid process, its main body pipeline and branch line require to have the pipe fitting of different-diameter usually, and the connection of two kinds of different diameter pipe fittings needs the pipe joint of reducing usually as link, and big reduction nipple is the parts that are separated with pipeline.Usually the big reduction nipple that is adopted is mainly used in small-bore low-pressure line, needing to be used for the position of often mounting or dismounting or the usefulness that the final adjustment of threaded fitting pipeline is used in conduct, its connection form adopts SOCKET WELDING or scyewed joint usually, the internal surface of its point of attachment has pipe end to insert, and causes the fluid of being carried not smooth easily.Along with the development of petroleum chemical industry, engineering construction is tending towards maximization, complicated, and the pipe fitting that uses in the piping engineering is tending towards variation according to the difference of working condition.Wherein be used for the big reduction nipple that the different size pipe fitting connects, its Environmental Conditions requires very harsh.
Summary of the invention
In order to overcome the deficiency in the background technique and to satisfy the diversified requirement of piping engineering, the utility model discloses a kind of big reduction nipple, described big reduction nipple is provided with the pipe nipple mouth by the upper end at the bowl-type body, following pipe nipple mouth is set to adapt to the demand that big change connects by the road in the lower end of bowl-type body, so the utlity model has simple in structure, install simple and easy, easy to use, save man-hour, can satisfy the technical requirements of the defeated reducing of complicated pipe.
For achieving the above object, the utility model adopts following technological scheme:
A kind of big reduction nipple comprises the bowl-type tube body, and the upper end of described bowl-type pipe is set to the little mouth of pipe in upper end, and the lower end of described bowl-type pipe is set to the big mouth of pipe in lower end, and the caliber of bowl-type pipe is gradual change.
Described big reduction nipple, bowl-type tube shape are set to bowl-type, funnel shape or T shape.
Described big reduction nipple, bowl-type pipe, the big mouth of pipe of the little mouth of pipe in upper end and lower end can be set to one.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
Big reduction nipple described in the utility model is respectively arranged with the little mouth of pipe in upper end and the big mouth of pipe in lower end owing to having adopted on same body, and the big mouth of pipe bore in the little mouth of pipe in upper end and lower end is a different-diameter, can satisfy the purpose that the different size pipe fitting connects in the piping engineering; Can satisfy pipe fitting connection technique requirement complicated and changeable, overcome the disadvantage that existing pipe fitting connects; The utlity model has simple in structure, cost is low, advantage such as safe and reliable.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a generalized section of the present utility model;
In the drawings: 1, the little mouth of pipe in upper end; 2, bowl-type pipe; 3, the big mouth of pipe in lower end.
Embodiment
The embodiment who provides is in conjunction with the accompanying drawings further specified structure of the present utility model:
As shown in Figure 1, 2, a kind of big reduction nipple comprises the bowl-type tube body, and the upper end of described bowl-type pipe 2 is set to upper end tubule mouth 1, and the lower end of described bowl-type pipe 2 is set to the big mouth of pipe 3 in lower end, and the caliber of bowl-type pipe 2 is gradual change; Bowl-type pipe 2 shapes are set to bowl-type, funnel shape or T shape; Bowl-type pipe 2, the big mouth of pipe 3 of upper end tubule mouth 1 and lower end can be set to one.
Upper end tubule mouth 1 connected small-sized pipeline when described big reduction nipple used, and the big mouth of pipe 3 in lower end connects large-scale pipeline, can satisfy the requirement of the flow and the flow velocity of different fluid; Can be used for the connection of the different two tubes of size.The middle part of bowl-type pipe 2 is the gradual change of camber line shape, during use, can make things convenient for pipe fitting to connect, and makes the smooth process of fluid, prevents flow resistance.
Claims (3)
1. a big reduction nipple comprises the bowl-type tube body, it is characterized in that: the upper end of described bowl-type pipe (2) is set to the upper end little mouth of pipe (1), and the lower end of described bowl-type pipe (2) is set to the big mouth of pipe in lower end (3), and the caliber of bowl-type pipe (2) is gradual change.
2. big reduction nipple according to claim 1 is characterized in that: bowl-type pipe (2) shape is set to bowl-type, funnel shape or T shape.
