Abstract

The utility model discloses an equipment for detecting tubular product inner wall, including an air cock of connecting the air supply, a bobble and a box body that holds the bobble, the diameter and the air cock diameter of bobble cooperate, the through-hole that the diameter is greater than the bobble is seted up to the side of box body. The utility model discloses can conveniently detect tubular product inner wall quality.

Description

Equipment for detecting inner wall of pipe

Technical Field

The utility model belongs to the technical field of hot-water heating tubular product, especially, relate to an equipment for detecting tubular product inner wall.

Background

The water heating pipe material prepared by high molecular material, such as PP pipe, aluminum plastic composite pipe, etc., can usually be dozens of meters or even hundreds of meters long, and in the production process, the problems of uneven inner wall and the like can be caused because of possible error caused by temperature or time control. Obviously, this is not a standard and a satisfactory product necessarily requires a smooth inner wall and a uniform inner diameter. Therefore, it is necessary to detect it before shipment. In the prior art, no convenient and practical special equipment is provided.

Disclosure of Invention

The utility model aims at providing an equipment for detecting tubular product inner wall.

Therefore, the utility model discloses a technical scheme is like this: a equipment for detecting tubular product inner wall which characterized in that: the air faucet comprises an air faucet connected with an air source, a small ball and a box body for containing the small ball, wherein the diameter of the small ball is matched with the diameter of the air faucet, and a through hole with the diameter larger than that of the small ball is formed in the side face of the box body.

Furthermore, the inner wall of the box body is coated with a buffer material.

The air faucet and the box body are fixed on the same frame.

The utility model discloses a use is like this: the small ball is placed into the pipe to be tested, one end of the pipe to be tested is connected with the air faucet, the other end of the pipe to be tested extends into the box body through the through hole in the side face of the box body, the air source is opened, and the high-pressure air pushes the small ball to move in the pipe until the small ball rushes out from the other end of the pipe and falls into the box body. Because the diameter of the small ball is adaptive to the specification of the pipe, if the inner wall of the pipe is not standard, the small ball can not be smoothly flushed out from the other end when encountering obstacles; therefore, the process is smooth, and the inner wall of the pipe can be judged to be qualified. Simultaneously, the utility model discloses can also judge whether the pipe wall is good, if leak gas department such as crack, can reflect in the operation of bobble equally. The small balls are generally steel balls, and have large impact force when being punched out of the pipe, and after the buffering material is coated in the box body, the impact can be slowed down, and the service life of the box body is prolonged.

It is visible, the utility model discloses can conveniently detect tubular product inner wall quality.

Drawings

Fig. 1 is a schematic diagram of the present invention.

Detailed Description

See the drawings. This embodiment includes frame 1, is equipped with air compressor 2 as the air supply under the frame, and fixed mounting has air cock 3 and box body 4 in the frame, and air cock 3 passes through the trachea and links to each other with air compressor machine 1. The box body 4 is a square box with an open top surface, and a through hole 5 is formed in the side surface of the box body. Steel balls (not shown) are placed in the box body.

When the device works, one end of a pipe to be measured is placed into the steel ball and then connected with the air nozzle 3, and the other end of the pipe to be measured extends into the through hole 5. The steel balls are consistent with the inner diameter of the pipe to be measured to form clearance fit; and (3) starting the air compressor 1, ejecting high-pressure air from the air nozzle to push the steel balls to run in the pipe to be tested until the pipe to be tested is flushed out, and dropping back into the box body 4.

Claims
