Description

Technical Field

[0001] This application relates to the field of high-pressure valve hydraulic testing technology, and in particular to a hydraulic testing fixture. Background Technology

[0002] In the shipbuilding industry, hydraulic testing equipment is used for pressure testing and performance evaluation of various pressure vessels, hoses, stainless steel pipelines, valves, and other hydraulic equipment. It mainly consists of pressure gauges, pressure controllers, measuring devices, and test specimen connectors. The main body of the equipment is mostly made of stainless steel, and it has one inlet and one outlet, performing a single pressure test at a time.

[0003] The above solution has many drawbacks, such as:

[0004] 1. The main body of the device is made of stainless steel, which cannot guarantee safety under high-pressure testing conditions (above 50MPa);

[0005] 2. The product testing interface of the hydraulic testing device is fixed, which can only test products with one interface size, resulting in low economic efficiency and lack of interchangeability.

[0006] 3. Because the pressure increase speed of a single oil inlet is relatively slow, which affects working efficiency, a single oil inlet does not have the ability to increase the pressure increase speed;

[0007] 4. The hydraulic testing device uses the hydraulic oil in the device repeatedly, which will reduce cleanliness, contaminate the equipment, and shorten its service life. Summary of the Invention

[0008] This application provides a hydraulic testing fixture to solve the problem in related technologies where the pressure increase speed of a single oil inlet is slow, affecting work efficiency, and therefore a single oil inlet does not have the ability to increase the pressure increase speed.

[0009] This application provides a hydraulic testing fixture, which includes:

[0010] An adapter seat is provided with a hydraulic oil chamber inside. The two ends of the hydraulic oil chamber pass through the adapter seat to form two adapter ports on the adapter seat. An outlet interface is provided on the adapter seat and communicates with the hydraulic oil chamber.

[0032] The beneficial effects of the technical solution provided in this application include:

[0033] The hydraulic testing fixture provided in this application has an adapter seat with two adapter ports that communicate with the hydraulic oil chamber.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] See Figure 1 and Figure 2 As shown in the figure, this application provides a hydraulic testing fixture, which includes an adapter seat 1, an inlet connector 2, an expansion assembly, an outlet assembly, a pressure sensor 5, and a pressure relief assembly 6. The adapter seat 1 has a hydraulic oil chamber 10 for hydraulic oil to enter. Both ends of the hydraulic oil chamber 10 penetrate the adapter seat 1 to form two adapter ports on the adapter seat 1. The adapter seat 1 has an outlet interface 11 that communicates with the hydraulic oil chamber 10. The inlet connector 2 is located on one of the adapter ports and can be screwed to the pressure testing connector of a pressure testing device, preferably. The inlet connector 2 is screwed onto the adapter port for easy installation and removal; the expansion assembly includes a screw plug 3 and an inlet connector 2, one of which is screwed onto the other adapter port; the outlet assembly includes an outlet connector 4, which is installed on the outlet interface 11; the pressure sensor 5 is installed on the adapter seat 1 and is used to measure the pressure in the hydraulic oil chamber 10; the pressure relief assembly 6 is installed on the adapter seat 1 and communicates with the hydraulic oil chamber 10. After the pressure holding test is completed and the pressure testing equipment is turned off, the pressure can be relieved through the pressure relief assembly 6.

[0040] The hydraulic testing fixture provided in this application embodiment has an adapter seat 1 with two adapter ports that communicate with the hydraulic oil chamber 10. One adapter port is directly connected to the inlet connector 2, while the other adapter port can be selected to connect to the screw plug 3 or the inlet connector 2 according to the actual pressure increase speed requirements. When both adapter ports use the inlet connector 2, the pressurizing equipment can be connected in series with the two inlet connectors 2 at the same time, thereby increasing the pressure increase speed and improving the working efficiency. Therefore, this application can solve the problem that a single oil inlet port does not have the ability to increase the pressure increase speed.

[0041] To prevent oil leaks, see Figure 1 As shown, a sealing gasket 7 is provided between the inlet connector 2 and the adapter port; a sealing gasket 7 is provided between the outlet connector 4 and the adapter port; and a sealing gasket 7 is provided between the screw plug 3 and the adapter port.

[0042] Sealing gasket 7 can be made of stainless steel combination sealing gaskets, etc.

[0043] To meet the testing needs of various product specifications and improve interchangeability and cost-effectiveness, see [link / reference]. Figure 1 As shown, the outlet assembly includes multiple outlet connectors 4, and all outlet connectors 4 included in the outlet assembly are selectively screwed onto the outlet interface 11; among all outlet connectors 4 included in the outlet assembly, at least a portion constitutes a type A connector, in which the outlet connector 4 is provided with an external thread for connecting the product connection end of the product to be tested, and the type A connector includes several outlet connectors 4 with different outer diameters of the product connection end.

[0044] In the Class A connector, the outlet connector 4 is provided with a product connection end, which adopts an external thread form to be screwed with the product to be tested. This can be adapted to the product to be tested with internal threads. At the same time, since the thread size of the product to be tested is different, the Class A connector includes several outlet connectors 4 with different outer diameters of the product connection end to accommodate different thread sizes of the product to be tested.

[0045] To meet the testing needs of various product specifications and improve interchangeability and cost-effectiveness, see [link / reference]. Figure 1 As shown, the outlet assembly includes multiple outlet connectors 4, and all outlet connectors 4 included in the outlet assembly are selectively screwed onto the outlet interface 11; among all outlet connectors 4 included in the outlet assembly, at least a portion constitutes a type B connector, in which the outlet connector 4 is provided with an internal thread for connecting the product connection end of the product to be tested, and the type B connector includes several outlet connectors 4 with different inner diameters of the product connection end.

[0046] In the type B connector, the outlet connector 4 is provided with a product connection end, which is in the form of an internal thread to be screwed into the product to be tested. This can be adapted to the product to be tested with an external thread. At the same time, since the thread size of the product to be tested is different, the type B connector includes several outlet connectors 4 with different inner diameters of the product connection end to accommodate different thread sizes of the product to be tested.

[0047] Furthermore, in order to perform tests on multiple products under test simultaneously, see [link to relevant documentation]. Figure 1 As shown, multiple outlet interfaces 11 are provided, and each outlet interface 11 can be equipped with an outlet connector 4.

[0048] Reusing hydraulic oil reduces cleanliness, contaminates equipment, and shortens its lifespan. To address this issue, see [link to relevant documentation]. Figure 1As shown, the hydraulic oil chamber 10 is equipped with an inlet filter 8 for filtering the hydraulic oil entering the hydraulic oil chamber 10 through the adapter port. The inlet filter 8 filters hard particles, heavy dirt, and other impurities before the hydraulic oil enters the internal pipeline, preventing wear and corrosion of system components, reducing the probability of sedimentation and adhesion, and improving the overall reliability of the equipment.

[0049] Since stainless steel cannot guarantee safety under high-pressure testing conditions (above 50MPa), to address this issue, the main body of the hydraulic testing device in this application is made of titanium alloy, while the others are made of duplex stainless steel, meeting the strength requirements for high-pressure testing (above 50MPa). For example, as an example, the adapter seat 1 is made of titanium alloy, while the inlet connector 2, screw plug 3, and outlet connector 4 are made of duplex stainless steel.

[0050] See Figure 2 As shown, the pressure relief assembly 6 includes a ball valve 60 and a transition joint 61. The ball valve 60 is connected to the adapter seat 1 via the transition joint 61. The ball valve 60 can be an ultra-high pressure ball valve, which maintains the internal pressure and monitors the internal pressure changes in real time using a digital display pressure sensor.

[0051] The advantages of this application, which includes a ball valve 60 and a transition joint 61, are as follows: during the pressurization process, the ball valve 60 is in a closed state. After the test is completed and the digital display pressure sensor returns to zero, the pressure is released through the ball valve 60. The ball valve 60 can completely release the oil pressure in the hydraulic test fixture, thereby protecting the safety of the hydraulic test fixture.

[0052] To prevent oil leaks, see Figure 2 As shown, a sealing gasket 7 is provided between the ball valve 60 and the transition joint 61, and a sealing gasket 7 is provided between the transition joint 61 and the adapter seat 1.

[0053] Further, see Figure 1 As shown, the pressure sensor 5 is a digital display pressure sensor, the pressure sensor 5 is connected to a power supply 9, and a sealing gasket 7 is provided between the pressure sensor 5 and the adapter seat 1.

[0054] In summary, the hydraulic testing device provided in this application is primarily made of titanium alloy, with detachable joints, exhibiting high strength and interchangeability, and is adaptable to various tested devices. The hydraulic testing device features series-connectable oil inlets, improving working efficiency, and the inlet filter maintains the cleanliness of the circulating hydraulic oil, ensuring the reliability of the device.
