Description

A low-pressure water pipe quick connection device

technical field

The utility model relates to the technical field of water pipe fast appliances, in particular to a low-pressure water pipe fast connection device.

Background technique

In the middle and late stage of the first generation of blast furnace, the stave inside the blast furnace body begins to crack and break gradually, which requires monitoring and repair of the partially cracked stave, and the repaired stave needs water to test the repair effect , the conventional method is to carry out by welding steel pipes or connecting rubber pipes. This approach has the following disadvantages:

1. The operation process is complicated, and the on-site operation space is narrow, which is not conducive to welding operation, which makes the construction difficult, and the welding seam is prone to defects such as pores and cracks, which eventually leads to uncontrollable pressure testing process;

2. It takes a long time to test the water and pressurize each time (an average of 2 hours each time).

3. Due to the complex process and steps, 3 to 4 people are required to cooperate, which increases a lot of manpower waste.

Utility model content

The utility model provides a quick connection device for low-pressure water pipes, aiming at the repairing effect of cooling walls after the current method of welding steel pipes or connecting rubber pipes to detect and repair the cooling wall, which brings complicated operation procedures and narrow on-site operation space. It is not conducive to the welding operation, which makes the construction difficult, and the welds are prone to defects such as pores and cracks, which eventually leads to the uncontrollable problem of the pressure test process.

In order to achieve the above object, the technical scheme of the utility model is specifically as follows:

A quick connection device for low-pressure water pipes, comprising a connecting sleeve and a squeeze-deformed pipeline sealing mechanism, one end of the connecting sleeve is matched with a pressurized medium pipeline, and the other end of the connecting sleeve is connected with the squeeze-deformed pipeline sealing mechanism. The pipeline to be pressed is matched with the connection.

The extrusion-deformed pipe sealing mechanism includes an extrusion lock nut and a deformed rubber ring, and the deformed rubber ring and the extrusion lock nut are sequentially set on the connecting sleeve.

A support gasket is also provided on one side of the deformed rubber ring.

The support pads are metal support pads.

The utility model is a simple and flexible tool for connecting medium pipelines, which can be operated by one person to quickly realize the temporary connection of low-pressure medium pipelines, and is especially suitable for pressure and leak detection of pipeline containers. The labor intensity of operators is reduced, labor time is saved, work efficiency is improved, and the operation is simple and fast.

Compared with the prior art method, the utility model has the following advantages:

1. There are few on-site environmental constraints, and the temporary connection of the medium pipeline can be quickly realized, which is time-saving and efficient (an operation takes an average of 0.4 hours).

2. The connection device is easy to install and disassemble, and only needs one person to operate, saving labor costs.

3. The utility model has simple structure, low cost and can be used repeatedly.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Among them, 1. Connecting sleeve, 2. Squeezing lock nut, 3. Deformed rubber ring, 4. Support gasket.

Detailed ways

As shown in Figure 1, a quick connection device for low-pressure water pipes includes a connecting sleeve 1 and an extrusion deformation pipe sealing mechanism. The form pipe sealing mechanism is connected with the pipeline to be pressed, and the extrusion deformed pipe sealing mechanism includes a squeeze lock nut 2, a deformed rubber ring 3 and a support gasket 4, a support gasket 4, a deformed rubber ring 3, and a squeeze lock nut. The nuts 2 are sequentially set on the connecting sleeve 1, and the supporting gasket 4 is a metal supporting gasket.

When the utility model is in use, according to the different diameters of the connected medium pipelines, the connecting sleeves 1 with different diameters and lengths are processed in advance according to the drawings, and then the deformed rubber ring 3 with a slightly smaller inner diameter than the connected pipeline 1 is selected. In the form of drawings, it is assembled in advance. One end of the connecting sleeve 1 is connected to the pressurized medium pipeline with a rubber hose, and the other end is inserted into the inner diameter of the pipeline to be pressed. Use a wrench to clamp the connecting sleeve 1 with one hand, and use a wrench to turn it with the other hand Squeeze the lock nut 2, use the squeeze lock nut 2 to compress the deformed rubber ring 3, because the deformed rubber ring 3 gradually becomes smaller in the axial direction, and gradually expands in the radial direction, and finally expands to fill the inner diameter of the pipe to achieve a sealed connection purpose, and then open the front-end pipeline valve, pass water and pressure test, so as to achieve the purpose of quick connection test water.
