DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0021] As Figure 1 , Figure 4 shown: An electromechanical modular group pipe pressure testing device includes a bracket 1, a pressure testing mechanism, and a water source; the bracket 1 is used to support the horizontally placed pipe 2; the bracket 1 includes several "H"-shaped frames, the "H"-shaped frames are fixed on the support foundation, the crossbars of several "H"-shaped frames are flush, and the crossbars of several "H"-shaped frames form a platform for supporting the pipe; several pipes 2 are horizontally placed on the crossbars of the "H"-shaped frames.

[0022] The pressure testing mechanism is connected to the water source and is used to inject pressurized water into the pipe 2; the pressure testing mechanism includes a pressurized water main pipe 5, a pressurized water branch pipe 4, a water inlet pipe 9, a water outlet pipe 6, a booster pump 8, and a first blind plate 17; the booster pump 8 is connected to the water source through the water inlet pipe 9 and is connected to the pressurized water main pipe 5 through the water outlet pipe 6. The booster pump 8 sucks water from the water source, pressurizes it to the pipe test pressure, and then sends it into the pressurized water main pipe 5. Several pressurized water branch pipes 4 are connected in parallel to the pressurized water main pipe 5. A second blind plate 3 for sealing connection with the pipe 2 is connected to the pressurized water branch pipe 4. The pressurized water branch pipe 4 is connected to one side nozzle of the pipe 2 through the second blind plate 3, and the pressurized water branch pipe 4 passes through the second blind plate 3 and communicates with the inside of the pipe 2. The other side nozzle of the pipe 2 is connected with the first blind plate 17 to be closed; the water in the pressurized water main pipe 5 flows into the pipe 2 through the corresponding pressurized water branch pipe 4, and at the same time, multiple pipes 2 are subjected to pressure testing.

[0023] As Figure 2 shown: The pressurized water branch pipe 4 includes a first branch pipe 4.1, a hose 4.3, and a second branch pipe 4.2 connected in sequence. The hose 4.3 enables the pressurized water branch pipe 4 to be movable. The first branch pipe 4.1 is connected to the pressurized water main pipe 5, the second branch pipe 4.2 is connected to the second blind plate 3, a pressure gauge 15 and a gate valve 16 are installed on the first branch pipe 4.1. The test pressure of the current pipe 2 is monitored through the pressure gauge 15, and the pressure testing process of the pipe 2 is independently controlled through the gate valve 16.

[0024] A first valve 12 is installed on the water outlet pipe 6. The first valve 12 is used to control the pressure testing process of all pipes 2. A pressure relief pipe 13 is connected between the first valve 12 and the booster pump 8 on the water outlet pipe 6. A second valve 14 is installed on the pressure relief pipe 13. When the water supply pressure of the booster pump 8 is too high, it is relieved through the second valve 14.

[0025] A flange 5.1 is connected to the nozzle of the pressurized water main pipe 5. When the number of pressurized water branch pipes 4 on a section of the pressurized water main pipe 5 cannot meet the number of pipes that can be pressure-tested simultaneously, several pressurized water main pipes 5 are connected in series through the flange 5.1, and the nozzle of the outermost pressurized water main pipe 5 is connected with a third blind plate for sealing.

[0026] As Figure 3 shown in the figure: The pressure-testing mechanism is installed on the first mobile trolley 7. On one side of the frame of the first mobile trolley 7, there is a handle 7.1, and on the other side, there is a pressurized water main pipe support 7.2. The top of the pressurized water main pipe support 7.2 has a bayonet for clamping the pressurized water main pipe 5, and the pressurized water pump 8 is placed on the frame of the first mobile trolley 7.

[0027] The water source is the water tank 11, and the water tank 11 is placed on the second mobile trolley 10.

[0028] When the pressurized water pump 8 is started, the water first enters the pressurized water main pipe 5, and then enters the pipeline 2 through the pressurized water branch pipes 4 respectively. After injecting water for a period of time, the first valve 12 is closed, and by observing the change of the index of the pressure gauge 15, it can be known whether the pipeline is qualified. The design that multiple pressurized water branch pipes 4 on the pressure-testing device are connected to the same pressurized water main pipe 5 realizes the water circulation in the pressure-testing device. When it is necessary to pressure-test a single pipeline 2 in the group of pipelines alone, only the gate valve 16 on other pressurized water branch pipes 4 needs to be closed. The extendable design of the pressurized water main pipe 5 on the pressure-testing device increases the application range of the pressure-testing device. The pressure-testing device realizes the simultaneous pressure-testing of multiple pipelines 2 in the same system. Compared with single-pipeline pressure-testing, the pressure-testing efficiency is improved. The more pipelines in the same system are pressure-tested simultaneously, the less relative pressure-testing time a single pipeline occupies, and the higher the efficiency. Therefore, the entire pressure-testing device improves the pressure-testing efficiency, has many applicable working conditions, and realizes water circulation.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
