Description

A pressure detection device for a container

technical field

The utility model relates to a detection device, in particular to a pressure detection device for a container.

Background technique

At present, in the machinery manufacturing industry, some workpieces used as containers, such as oil coolers, air coolers, etc., have a working pressure of 0.2-0.3 MPa. After the manufacturing is completed, they must be tested at a test pressure above 0.6 MPa. . The traditional pressure detection equipment uses a manual plunger pump as the detection equipment. The rocker arm of the plunger pump is shaken by hand, and the water in the water storage tank is sent into the workpiece through the up and down movement of the piston. When the pressure inside the workpiece reaches 0.6MPa Finally, close the gate valve, if there is no leakage within a certain period of time, and the pressure will not drop, a pressure test of the workpiece will be completed. Because the inner cavity of the workpiece is relatively complex, the entire inner cavity cannot be filled when adding water. Therefore, it is necessary to use a plunger pump to continue adding water to the inner cavity. Shake the rocker once, and the amount of water sent is small, so it is necessary to shake the rocker several times. , The operation is laborious and time-consuming; when the workpiece leaks, it is necessary to shake the rocker arm while judging the leak point. One person cannot complete it. Two people are needed, one person shakes the rocker arm, and the other observes the leak point of the workpiece. The disadvantages of this manual plunger pump pressure detection equipment are as follows:

1. Manual operation is labor-intensive.

2. Low efficiency.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the traditional detection equipment using a manual plunger pump to provide a new pressure detection device for a container.

The technical scheme of the utility model is as follows:

A container pressure detection device with a detection range of 0 to 1 MPa, which includes a water storage tank, a gate valve, a pressure gauge, a connecting pipe, and a workpiece, and is characterized in that it also includes an air compressor and a gas pipe; the container pressure detection device The air compressor is used as the power, and the medium for transmitting pressure includes air and water; the air compressor, air pipe, water storage tank, gate valve, connecting pipe and workpiece are connected in sequence; the gate valve can connect the inside of the workpiece and The water storage tank is divided into two separate parts; the pressure gauge is located between the gate valve and the workpiece.

The water storage tank is a steel plate welded structure, the weld seam is dense, and can withstand 1MPa. The water storage tank can be a cylinder, a cuboid, or a cube.

The air pipe is an air hose with a working pressure of 1MPa.

The connecting pipe is made of cotton braided hose, and its working pressure is 1MPa.

The water storage tank is provided with a water inlet and a water outlet, and both the water inlet and the water outlet are tightly sealed with screw plugs and rubber pads.

Compared with the existing technology, the utility model has the following advantages:

1. Using an air compressor to pressurize, compared with manual operation, the labor intensity is lower.

2. The operation time is short, and the test pressure can be reached inside the workpiece in only ten seconds, and the labor efficiency is high.

3. The detection quality is high. If the workpiece leaks, due to the continuous pressure of the air compressor, there will be signs of continuous water leakage at the leak point, which is easy to judge.

4. Both the air pipe and the connecting pipe are flexible pipes, and are equipped with quick-change pipe joints, which are easy and convenient to install and disassemble.

5. Labor saving, a single person can complete the work of pressure testing of the workpiece.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a structural representation of the utility model. The utility model is composed of an air compressor 1, an air pipe 2, a water storage tank 3, a gate valve 4, a pressure gauge 5, a connecting pipe 6 and a workpiece 7. The air compressor 1 is provided with an air valve 8 for opening the air compressor, and the air pipe 2 It is connected to the air compressor 1 and the water storage tank 3, the air pipe 2 is provided with a quick-change pipe joint 13, the water storage tank 3 is provided with a water inlet 9 and a water outlet 10, and the water inlet 9 and the water outlet 10 adopt screw plugs 11 and rubber pads 12 Press and seal, the gate valve 4 is set between the water storage tank 3 and the workpiece 7, which is to communicate or block the passage of water between the water storage tank 3 and the workpiece 7, and the pressure gauge 5 and the pressure gauge 5 are set between the gate valve 4 and the workpiece 7 The water pressure inside the workpiece 7 can be accurately displayed, and the connecting pipe 8 is provided with a quick-change pipe joint 13 .

In conjunction with Fig. 1, the utility model uses the air compressor 1 as the power, and the transmission route of its pressure is: air compressor 1 → air pipe 2 → water storage tank 3 → gate valve 4 → pressure gauge 5, connecting pipe 6 → workpiece 7, the transmission The pressure media are air and water. Unscrew the screw plug 11 of the water inlet 9 of the water storage tank 3, fill the water storage tank 3 with water, tighten the screw plug 11, open the gate valve 8 of the air compressor 1, and the compressed air will flow into the water storage tank 3 through the air pipe 2, The water in the gas compressed water storage tank 1 passes through the gate valve 4, the pressure gauge 5 and the connecting pipe 6, and then flows into the workpiece 7. When the pressure gauge 5 reaches 0.6MPa, close the gate valve 4 and the gate valve 4 of the air compressor 1, and open the fast valve of the air pipe 2. Change the pipe joint 13, observe whether the workpiece 7 leaks, judge whether the workpiece 7 is qualified, if leak then find out the leak point, like this, just complete the pressure detection of the workpiece 7. After the pressure test of the workpiece 7, the quick-change pipe joint 13 of the gas pipe 2 and the connecting pipe 6 is opened to facilitate the movement of the pressure detection equipment of the container.
