Description

Water pipeline pressure test device

technical field

The utility model relates to a device for pressure testing of water pipelines.

Background technique

At present, in building construction, the pipeline pressure test usually adopts methods such as opening holes on the pipeline or making on-site pressure test fittings, etc., but this traditional pressure test method causes great damage to the pipeline, and is costly and labor-intensive. , and there are problems such as pressure resistance and poor sealing.

Utility model content

The technical problem to be solved by the utility model is to provide a device for pressure testing of water pipes, which has a simple and reasonable structure, is convenient to manufacture, is safe and reliable to use, saves time and effort, saves construction costs, and improves work efficiency.

In order to achieve the above object, the utility model water pipeline pressure test device includes a blocking plate, a pressure gauge, a gauge pipe, an exhaust pipe, a valve and a water inlet and outlet pipe. The blocking plate is a circular steel plate, which can be cut from a steel plate with a thickness of 10mm. As a result, mounting holes are evenly distributed along the circumference of the blocking plate, and the pitch and aperture of each mounting hole correspond to the pitch and aperture of the screw holes on the flange at the end of the pipeline. A circular hole is provided in the upper part of the blocking plate, and an exhaust pipe is welded on the outer end surface on the right side of the circular hole. A valve is installed at the right end of the exhaust pipe, and a gauge pipe is welded on the right end section of the exhaust pipe, and the gauge pipe communicates with the exhaust pipe. A pressure gauge is installed on the gauge tube. A circular hole is provided at the lower part of the blocking plate, and a water inlet and outlet pipe is welded on the outer end surface on the right side of the circular hole. A valve can be installed at the right end of the water inlet and outlet pipes.

When in use, connect the blocking plate of the device to the flange of the pipe mouth firmly with bolts, then inject water into the pipe through the water inlet and outlet pipes, and at the same time open the valve on the exhaust pipe to exhaust outwards, when it is filled with water, close it The valve carries out boosting and maintaining pressure, and the pressure change can be observed through the pressure gauge. After the pressure is completed, the connecting pipe at the right end of the inlet and outlet pipes is removed, and the water in the pipe can be discharged.

The device for pressure testing of water pipes proposed by the utility model has a simple and reasonable structure, is convenient to manufacture, is safe and reliable to use, saves time and effort, saves construction costs, and improves work efficiency.

Fig. 1 is a structural schematic diagram of a device for pressure testing of a water pipeline.

Detailed ways

Referring to the accompanying drawings, the device for water pipeline pressure test includes a blocking plate 1, a pressure gauge 2, a gauge pipe 3, an exhaust pipe 4, a valve 5, and an inlet and outlet pipe 6. The blocking plate is a circular steel plate, and a steel plate with a thickness of 10mm can be used. Cutting is made, and the mounting holes are evenly distributed along the circumferential direction on the blocking plate, and the pitch and aperture of each mounting hole are corresponding to the pitch and aperture of the screw holes on the flange at the end of the pipe. A circular hole is provided in the upper part of the blocking plate, and an exhaust pipe is welded on the outer end surface on the right side of the circular hole. A valve is installed at the right end of the exhaust pipe, and a gauge pipe is welded on the right end section of the exhaust pipe, and the gauge pipe communicates with the exhaust pipe. A pressure gauge is installed on the gauge tube. A circular hole is provided at the lower part of the blocking plate, and a water inlet and outlet pipe is welded on the outer end surface on the right side of the circular hole. A valve can be installed at the right end of the water inlet and outlet pipes.

When in use, connect the blocking plate of the device to the flange of the pipe mouth firmly with bolts, then inject water into the pipe through the water inlet and outlet pipes, and at the same time open the valve on the exhaust pipe to exhaust outwards, when it is filled with water, close it The valve carries out boosting and maintaining pressure, and the pressure change can be observed through the pressure gauge. After the pressure is completed, the connecting pipe at the right end of the inlet and outlet pipes is removed, and the water in the pipe can be discharged.

The device for pressure testing of water pipes proposed by the utility model has a simple and reasonable structure, is convenient to manufacture, is safe and reliable to use, saves time and effort, saves construction costs, and improves work efficiency.
