Abstract
The utility model discloses a U-shaped tube pressure test fixture which comprises a pressure plate, a blocking plate, a stop valve and a water inlet tube. Two through holes which are corresponding to two ports of a U-shaped tube are arranged on the pressure plate. Two holes which are corresponding to two ports of the U-shaped tube are arranged on the blocking plate, wherein one hole is a through hole, and the other hole is a blind hole. The pressure plate and the blocking plate are connected through a bolt. The stop valve is connected with the water inlet tube. The U-shaped tube is arranged in the through holes of the pressure plate and is pressed. One end of the U-shaped tube is sealed by the blind hole of the blocking plate, and the other end is connected with the stop valve. The other end of the stop valve is connected with the water inlet tube. The water inlet tube is connected with a pressure machine. The pressure machine is started, and the process of U-shaped tube welding joint leak detection is completed under the test pressure. The U-shaped tube pressure test fixture provided by the utility model has the advantages of simple structure and pressure test method, thus the work efficiency is improved.
Description
Technical field
The utility model relates to pressure experimental device, the structure for pressure test especially U-shaped pipe open joint sealing detected.
Background technology
U-shaped pipe heat transmission equipment is mainly used in the industry such as Coal Chemical Industry, petrochemical complex.The pattern of U-shaped pipe is varied, and fin heat exchange pipe, light pipe etc. are arranged, and because the u bent tube radius is too small, needs the U-shaped pipe bend of docking, for guaranteeing the quality of welding joint, before assembling, must carry out hydro-test by Welded Joints, guarantees that joint is without leakage.In the open joint leak test of the U-shaped pipe of fin type heat exchanger, due in air cooler, U-shaped pipe quantity is more, and the elbow radius is less, and joint is more, to testing, brings terrible a large amount of workload.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy, U-shaped pipe structure for pressure test of fast detecting U-shaped pipe adapter quality.
For solving the problems of the technologies described above, a kind of U-shaped pipe of the utility model structure for pressure test, comprise pressing plate, closure plate, stop valve and water inlet pipe, has two through holes corresponding to U-shaped pipe two-port on pressing plate; Also have two holes corresponding to U-shaped pipe two-port on closure plate, one of them is through hole, and another is blind hole; Pressing plate and closure plate are bolted, and stop valve is connected with water inlet pipe.
During use, the U-shaped pipe is placed in the interior also compression of through hole of pressing plate, and U-shaped Guan Yiduan is by the sealing of closure plate blind hole, and the other end connects stop valve; The other end of stop valve connects water inlet pipe, and water inlet pipe is connected with pressing machine, and the starting pressure machine, under test pressure, becomes the process of U-shaped pipe welding joint leak detection.
The utility model provides a kind of avoiding device before assembling, U-shaped pipe open joint sealing detected, be specially adapted to the U-shaped pipe of heat interchanger, its structure and pressure-measuring method are simple, save human and material resources, improved work efficiency, the effect of Welded Joints leak detection be can effectively reach, the quality of product and the security of product guaranteed.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

The structural representation that Fig. 2 is pressing plate.
In figure, 1-pressing plate, 2-closure plate, 3-stop valve, 4-water inlet pipe, 5-U shape pipe, 6-bolt.
Embodiment
As shown in Figure 1, a kind of U-shaped pipe of the utility model structure for pressure test, comprise pressing plate 1, closure plate 2, stop valve 3 and water inlet pipe 4, has two through holes corresponding to U-shaped pipe 5 two-port on pressing plate 1.U-shaped pipe 5 is fixed in the through hole of pressing plate.Also have two holes corresponding to U-shaped pipe 5 two-port on closure plate 2, one of them is through hole, and another is blind hole; Pressing plate 1 is connected by bolt 6 with closure plate 2.U-shaped pipe 5 one ends are by closure plate 2 blind hole sealings, and the other end is by connecting stop valve 3 after the upper through hole of closure plate 2.Stop valve 3 is connected with water inlet pipe 4, and water inlet pipe 4 is connected with pressing machine, and the starting pressure machine, under test pressure, becomes the process of U-shaped pipe welding joint leak detection.
On the basis of above structure, described pressing plate 1 is formed by bolt 6 is fastening by upper and lower two pressing plates, all has two grooves on any one pressing plate, after upper lower platen amalgamation, forms through hole.Push down heat exchanger U-shaped pipe by upper lower platen, then compress by clamp nut, tight a bolt fixing.This structure can make pressing plate conveniently and compress securely the U-shaped pipe.
Be provided with rubber gasket on the surface of contact of U-shaped pipe 5 ports and pressing plate 1 and closure plate 2, can further improve the sealing of pressure testing pipeline.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have multiple change and variation, all any modifications within spirit of the present utility model and principle, improves and is equal within replacement all should be included in protection domain of the present utility model.
