Description

Pipe penetrating tool

Technical Field

The invention relates to the technical field of pipe penetrating, in particular to a pipe penetrating tool.

Background

The shell-and-tube heat exchanger is also called a shell-and-tube heat exchanger. The dividing wall type heat exchanger takes the wall surface of the tube bundle sealed in the shell as a heat transfer surface. The heat exchanger has simple structure, low cost, wider flow cross section and easy scale cleaning; but has low heat transfer coefficient and large occupied area. Can be made of various structural materials (mainly metal materials), can be used at high temperature and high pressure, and is the most widely applied type.

Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1 to 4, the invention discloses a pipe penetrating tool, which comprises a conical head 1, a sleeve 2, a conical end 3 and a fixing sleeve 4, wherein the conical head 1 comprises a top head 101 and a cone 102, the bottom end of the top head 101 is fixedly connected with the top end of the cone 102, the top head 101 is in the shape of a cone and a cylinder, the cylinder in the top head 101 is fixedly connected with the cone 102, the cone 102 is inserted into the sleeve 2, and the connecting end surface of the top head 101 and the cone 102 is connected with the top end of the sleeve 2.
