Abstract
The utility model discloses a kind of poling anticreep guide head, it is characterized in that, comprise tube brush and the guide head of brazing in tube brush end, this guide head comprises taper guide head and joint, and the threaded one end of joint connects taper guide head, other end brazing tube brush.The utility model has the advantages that: 1, structure is simple, be easy to make; 2, with heat exchanger tube inwall compact siro spinning technology, difficult drop-off, enhances productivity; 3, nylon material guide head and tube brush, can not damage heat exchanger tube inwall; Even if by the cavity ring of brush holder afterbody when 4 guide heads come off, seeker conveniently can be taken out in tube bank.
Description
Technical field
The utility model relates to a kind of poling anticreep guide head device, is specifically related to the anticreep guide head that heat exchange equipment in the unit such as thermoelectricity, nuclear power uses when poling.
Background technology
In the process manufacturing heat exchanger, heat exchanger tube is the carrier realizing heat exchange work, and therefore its installation is most important step, by heat exchanger tube through deflection plate and tube sheet.Due to deflection plate and tube sheet being equipped with pore, in assembling process, both form assembling tolerance, and therefore heat exchanger tube is difficult to directly correctly pass through, so need to install poling guide head in heat exchanger tube front end.In heat exchanger tube poling process, guide head easily clashes into deflection plate or tube sheet, is formed and shakes, make can not keep between guide head and heat exchanger tube closely cooperating, and final guide head easily drops and be difficult to taking-up in the middle of equipment.
Summary of the invention
The technical problems to be solved in the utility model prevents guide head from coming off in heat exchanger tube is smoothly by the process of deflection plate and tube sheet pore, comes off also easily take out even if further technical problem to be solved in the utility model is guide head.
In order to solve the problems of the technologies described above, the technical solution of the utility model there is provided a kind of poling anticreep guide head, it is characterized in that, comprise tube brush and the guide head of brazing in tube brush end, this guide head comprises taper guide head and joint, the threaded one end of joint connects taper guide head, other end brazing tube brush.
Preferably, described tube brush comprises brush holder and brush, and brush is wrapped on brush holder.
Preferably, the tail end of described brush holder is cavity ring structure.
The utility model has the advantages that:
1, structure is simple, is easy to make;
2, with heat exchanger tube inwall compact siro spinning technology, difficult drop-off, enhances productivity;
3, nylon material guide head and tube brush, can not damage heat exchanger tube inwall;
Even if by the cavity ring of brush holder afterbody when 4 guide heads come off, seeker conveniently can be taken out in tube bank.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat exchanger poling anticreep guide head described in the utility model.
Detailed description of the invention
For making the utility model become apparent, hereby accompanying drawing is coordinated to be described in detail below with preferred embodiment.
As shown in Figure 1, be a kind of poling anticreep guide head structural representation that the utility model provides, comprise taper guide head 1, joint 2, brush holder 3, brush 4; The front end of joint 2 is threaded with guide head 1, and preferably, guide head 1 is nylon material; The front end of brush holder 3 is connected with joint 2 brazing, and preferably, brush holder 3 afterbody is cavity ring structure; Brush 4 is wrapped in outside brush holder 3, and preferably, brush 4 is nylon material.
In poling process, brush 4 and heat exchanger tube inwall interference fit, be closely connected, not easily come off from pipe.When coming off, also by the cavity ring of brush holder 3 afterbody, seeker can be taken out.
