The connection method between the pressure-inducing pipe and the quick connector is quick plug-in and pull-out, and the O-ring is sealed. However, since the pressure-inducing method of the quick connector and the pressure-inducing pipe is often used in air environments, a set of pressure-inducing devices needs to be designed to verify the applicability of the quick connector and the pressure-inducing pipe in underwater pressurized environments.

[0019] e. If the pressure values ​​P1 and P2 remain constant, it means that the quick connectors JT1 and JT2 and the pressure pipe TB1 are sealed reliably; if the pressure values ​​P1 or P2 change, it means that the quick connectors JT1 and JT2 and the pressure pipe TB1 are not sealed well.

[0020] As a preferred solution, in step b, if the pressure value P2 exceeds the predetermined value, the valve QV4 is opened to drain the water and release the pressure to the predetermined value; in step d, if the pressure value P1 exceeds the predetermined value, the valve QV1 is opened to drain the water and release the pressure to the predetermined value.

To achieve the above purpose, the present invention is implemented through the following specific embodiments:

[0039] Example

[0040] This embodiment designs a quick connector and a pressure pipe pressure test device. The device has a simple structure, low manufacturing cost, and simple operation. It can test the underwater sealing performance of the quick connector and the pressure pipe. The structure diagram of the quick connector and the pressure pipe is shown in FIG. Figure 1 , see the composition of the pressure device Figure 2 This embodiment provides a reactor hydraulic simulation test quick connector and a pressure pipe pressure device, such as Figure 2As shown, it includes pressure container R1 / R2, quick connector JT1 / JT2 / JT3 / JT4 / JT5 / JT6, pressure pipe TB1 / TB2 / TB3, pressure pump PP, valve QV1 / QV2 / QV3 / QV4, pressure gauge PG1 / PG2;

[0041] The pressure vessels R1 and R2 have a plurality of quick connector interfaces. The quick connectors JT1 and JT2 are connected to the inside of the pressure vessel R1, and the quick connectors JT1 and JT2 are connected by a pressure pipe TB1; the quick connectors JT3 and JT4 are connected to the outside of the pressure vessel R1, and the quick connectors JT3 and JT1 share a quick connector interface, and the quick connectors JT4 and JT2 share a quick connector interface; the quick connectors JT5 and JT6 are connected to the outside of the pressure vessel R2, and the quick connectors JT4 and JT5 are connected by a pressure pipe TB2, and the quick connectors JT3 and JT6 are connected by a pressure pipe TB3;

[0042] The pressure containers R1 and R2 have a water injection interface, a pressure relief interface and a pressure gauge interface. The pressure pump PP is connected to the water injection interfaces of the pressure containers R1 and R2 respectively. The valve QV2 is arranged at the water injection interface of the pressure container R1, and the valve QV3 is arranged at the water injection interface of the pressure container R2; the valve QV1 is arranged at the pressure relief interface of the pressure container R1, and the valve QV4 is arranged at the pressure relief interface of the pressure container R2; the pressure gauges PG1 and PG2 are connected to the pressure gauge interfaces of the pressure containers R1 and R2 respectively.

[0043] The external environment of the quick connectors JT1, JT2 and the pressure pipe 1 in the pressure container R1 is water, and they are the structural parts to be pressure tested. The water pressure P1 in the pressure container R1 is measured by the pressure gauge PG1, and P1 is the external pressure of the quick connectors JT1, JT2 and the pressure pipe 1; the water pressure P2 in the pressure container R2 is measured by the pressure gauge PG2, and the water pressure P2 is transmitted to the quick connectors JT1, JT2 and the pressure pipe 1 through the quick connectors JT3, JT4, JT5, JT6, the pressure pipe 2 and the pressure pipe 3, and P2 is the internal pressure of the quick connectors JT1, JT2 and the pressure pipe 1. The pressure containers R1 and R2 are pressurized by the pressure pump PP, and the pressure containers R1 and R2 are depressurized by the ball valves QV1 and QV4. For convenience, Figure 2 Only the sealing pressure test of JT1, JT2 and the pressure-leading pipe 1 is illustrated. More pressure-leading joints and pressure-leading pipes can be arranged in the pressure vessel R1 as needed to achieve the purpose of batch pressure test.

[0044] First, the pressure vessel R2 is pressurized to P2 by the pressure pump PP, and then the pressure vessel R1 is pressurized to P1. QV1, QV2, QV3, and QV4 are closed to form a closed pressure space. The pressure is maintained for 5 minutes. If P1 and P2 remain constant, it means that the quick connectors JT1, JT2, and the pressure pipe 1 are sealed reliably and can be used for underwater pressure drawing. If P1 and P2 change, it means that the quick connectors JT1, JT2, and the pressure pipe 1 are leaking at the seal and cannot be used for underwater pressure drawing. When the internal pressure P2 of the quick connectors JT1, JT2, and the pressure pipe 1 is greater than the external pressure P1, the seal is generally reliable. When the internal pressure P2 of the quick connectors JT1, JT2, and the pressure pipe 1 is less than the external pressure P1, the seal may leak. The pressure test focuses on the sealing problem in this case.

[0045] Based on the above scheme, the water pressure P1 in the pressure container R1 is used to simulate the external pressure of the quick connector and the pressure pipe, and the water pressure P2 in the pressure container R2 is used to simulate the internal pressure of the quick connector and the pressure pipe; the pressure-testing device can simulate the installation environment of the quick connector and the pressure pipe, establish the internal and external pressures of the pressure pipe respectively, and test the sealing reliability of the quick connector and the pressure pipe under underwater pressure environment.

[0046] In an optional embodiment, if Figure 2 As shown, the connecting pipe between the pressure pump PP and the pressure vessels R1 and R2 has a pressure relief interface, and the valve QV5 is arranged at the pressure relief interface. The connecting pipe between the pressure pump PP and the pressure vessels R1 and R2 has a pressure gauge interface, and the pressure gauge PG3 is arranged at the pressure gauge interface.

[0047] According to the requirements of the quick connector and the pressure pipe pressure test, first design the pressure vessel R1, see Figure 3 , the pressure vessel R2 can be designed with reference to R1. In an optional embodiment, Figure 3 As shown, the pressure container R1 and / or R2 comprises a hollow cylinder and a flange, and the flange closes the upper and lower openings of the hollow cylinder to form a sealing structure. The quick connector interface, water injection interface, pressure relief interface, and pressure gauge interface are all arranged on the flange.

[0048] In an optional embodiment, the valves QV1 / QV2 / QV3 / QV4 / QV5 are ball valves.

[0049] The pressure test conditions to be established are the internal pressure P2 and the external pressure P1 of the quick connector and the pressure pipe. The test device is used to establish the above pressure test conditions. This embodiment provides a reactor hydraulic simulation test quick connector and pressure pipe test method. The reactor hydraulic simulation test quick connector and pressure pipe pressure device are used to implement the following steps:

[0050] First, fill the pressure vessels R1 and R2 with tap water. Figure 2 Install the threaded quick connector and pressure pipe as shown, and then connect all pipes and valves;

[0051] a. Close valves QV1, QV2, and QV5, open valves QV3 and QV4, and use the pressure pump PP to inject water into the pressure container R2 to increase pressure. When water comes out from the rear end of valve QV4, it means that the air in the pressure container R2 has been exhausted. At this time, close valve QV4;

[0052] b. After closing valve QV4, continue to gradually increase the pressure in pressure vessel R2 using pressure pump PP until the pressure gauge PG2 reading P2 reaches the preset value, and then close valve QV3; if the pressure value P2 exceeds the preset value, open valve QV4 to drain and release the pressure to the preset value;

[0053] After the pressure vessel R2 is filled with water and before the pressure vessel R1 is filled with water, the valve QV5 is opened to release the pressure at the rear end of the pressure pump PP to atmospheric pressure, and then the valve QV5 is closed;

[0054] c. Close valves QV3, QV4, and QV5, open valves QV1 and QV2, and use the pressure pump PP to inject water into the pressure container R1 to increase pressure. When water comes out from the rear end of valve QV1, it means that the air in the pressure container R1 has been exhausted. At this time, close valve QV1;

[0055] d. After closing valve QV1, continue to gradually increase the pressure in pressure vessel R1 using pressure pump PP until the pressure gauge PG1 reading P1 reaches the preset value, and then close valve QV2; if the pressure value P1 exceeds the preset value, open valve QV1 to drain and release the pressure to the preset value;

[0056] e. If the pressure values ​​P1 and P2 remain constant and can be maintained for 5 minutes, it means that the quick connectors JT1 and JT2 and the pressure pipe TB1 are sealed reliably and can be used for underwater pressure drawing; if the pressure values ​​P1 or P2 change, it means that the quick connectors JT1 and JT2 and the pressure pipe TB1 are not sealed well. After the pressure test is completed, open valves QV1 and QV4 in turn to release the pressure.

[0057] In summary, compared with the prior art, the present invention has the following advantages and beneficial effects:

[0058] 1. The pressure device can construct a closed space. The pressure pump PP can increase the internal pressure P2 and external pressure P1 of the quick connector and the pressure pipe, and the ball valves QV1 and QV4 can reduce P1 and P2 respectively;

[0059] 2. After establishing the P1 and P2 pressure conditions, test the sealing performance of the quick connector and the pressure pipe under the condition of differential pressure at both ends. If P1 and P2 can maintain pressure continuously, it proves that the quick connector and the pressure pipe are well sealed and can be used in underwater pressure measurement environment.

[0060] Therefore, the pressure test device can batch verify the applicability of underwater pressure measurement of quick connectors and pressure pipes, truly simulate the pressure inside and outside the pressure pipes, carry out pressure test tests under various working conditions, and detect whether there are leakage problems. It provides technical support for underwater pressure measurement in pressurized environments for related tests. It has certain market prospects.
