Description

Technical Field

[0001] This utility model relates to the field of water pressure testing technology, specifically to a valve body water pressure testing water supply circuit mechanism. Background Technology

[0002] A valve is a device used to control the flow of fluids (such as liquids and gases) in pipelines or equipment. It regulates parameters such as flow rate, pressure, and flow direction by changing the cross-sectional area of ​​the flow channel. Valves are widely used in many fields, including petroleum, chemical, metallurgy, power, and water supply and drainage. A valve pressure testing machine is a device specifically designed for pressure testing valves. It simulates the pressure environment of a valve in actual operation, applying different levels of pressure to the valve to test its sealing performance, strength, and other performance indicators.

[0003] Current pressure testing machines often only perform single water pressure or air pressure tests. For different models and types of valve products, companies need to purchase multiple machines, which significantly increases costs and occupies a lot of space. Furthermore, the water used in current water pressure testing machines is discharged after a single use, resulting in serious waste of water resources. In addition, the lack of filtration and purification of external water sources allows impurities in the water to easily enter the testing system, interfering with the accuracy of test results. It also affects the service life of pumps, pipelines and other equipment in the water supply system, increasing equipment maintenance costs. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1 to 5 This utility model provides a technical solution:

[0029] A valve body water pressure testing water supply circuit mechanism, comprising:

[0030] A cabinet 1 is provided, with a workbench fixedly connected to its top. A water supply system is installed inside the cabinet 1, including a 100-liter water tank 17 fixedly connected to the bottom of the cabinet 1. A level sensor 22 and a pH meter 23 are fixedly connected to the 100-liter water tank 17. A reverse osmosis water purifier 18 is installed on the 100-liter water tank 17, and the reverse osmosis water purifier 18 is connected to the 100-liter water tank 17 via a filter inlet valve 16. The reverse osmosis water purifier 18 is connected to an external water source via an inlet 24. A pneumatic booster pump 25 is also fixedly connected to the 100-liter water tank 17. The water supply system also includes a stainless steel high-pressure water pump 15 and a vacuum pump 14.

[0031] Specifically, the workbench is equipped with a test fixture 2 and a laser bubble counter 6 for testing product performance. The test fixture 2 includes a test sealing fixture 201 and a product fixing fixture 202.

[0032] Specifically, the vacuum pump 14 is fixedly connected inside the soundproof enclosure 13, the soundproof enclosure 13 is fixedly connected to the bottom of the machine cabinet 1, the stainless steel high-pressure water pump 15 is fixedly connected to the bottom of the machine cabinet 1, the stainless steel high-pressure water pump 15 is connected to a 100-liter water tank 17 and a branch pipe of the water pressure and air pressure common pipeline 19, the water pressure and air pressure common pipeline 19 has two branch pipes, and the other branch pipe of the water pressure and air pressure common pipeline 19 is connected to the pneumatic booster pump 25.

[0033] Specifically, the main pipe of the water pressure and air pressure common pipe 19 passes through the workbench and is connected to the test fixture 2 on the workbench, and is used to supply high pressure water to the test fixture 2. A high pressure valve 20 is also installed on the water pressure and air pressure common pipe 19.

[0034] In this embodiment, a reverse osmosis water purifier 18 is installed inside the machine cabinet 1. External water is introduced into the reverse osmosis water purifier 18 through the inlet 24. After filtration and purification, the filtered water is introduced into a 100-liter water tank 17 through the filter inlet valve 16. When water needs to be supplied to the test fixture 2, the vacuum pump 14 inside the machine cabinet 1 creates a vacuum in the workbench space inside the equipment through the vacuum pipe 1401. The stainless steel high-pressure water pump 15 on the side of the 100-liter water tank 17 draws water from the 100-liter water tank 17 and pressurizes it to generate high-pressure water. At this time, the valve between the water pressure and air pressure common pipe 19 and the stainless steel high-pressure water pump 15 is opened, and the valve between the water pressure and air pressure common pipe 19 and the pneumatic booster pump 25 is closed. The high-pressure water is transported through the water pressure and air pressure common pipe 19, through the workbench, and into the test valve body inside the test sealing fixture 201 for testing. The test sealing fixture 201... After the test valve body is tested, the industrial control computer automatically controls the valve on the working face return water pipe 21 to open. The working face return water pipe 21 then returns the tested water back to the water tank, thus forming a complete water supply circuit structure. Through this water supply circuit structure, the reverse osmosis water purifier 18 reduces equipment maintenance time, and the stainless steel high-pressure water pump 15 and the pneumatic booster pump 25 quickly increase pressure, shortening the test cycle and improving the working efficiency of the testing machine. By recycling, water waste is reduced, operating costs are lowered, and the process is more environmentally friendly. Furthermore, the reverse osmosis water purifier 18 installed in the machine cabinet 1 filters and purifies the external water source, removing impurities, particles, ions, and other harmful substances from the water to obtain water with high purity. This effectively prevents impurities from damaging the test valve body or affecting the accuracy of the test results, protecting other equipment in the entire water supply system and extending the service life of the equipment.

[0035] Specifically, the testing machine can be used to test 2-way valves and 3-way valves, manual valves and actuator-driven valves, etc. The testing machine can switch between water pressure and air pressure testing. When air pressure testing is required, the branch valve between the water pressure and air pressure common pipeline 19 and the stainless steel high-pressure water pump 15 is closed, and the branch valve between the water pressure and air pressure common pipeline 19 and the pneumatic booster pump 25 is opened. The external compressed air source is pressurized by the pneumatic booster pump 25, and the high-pressure gas is introduced into the test sealing fixture 201 for testing through the water pressure and air pressure common pipeline 19.

[0036] Specifically, whether the valve body water pressure test and sealing test need to be performed by hydraulic or pneumatic testing can be determined by the user as needed, and can be set on the industrial control computer touch screen of the main unit cabinet 7.

[0037] Specifically, the vacuum pump 14 is connected to the test fixture 2 through a vacuum pipe 1401, and the test fixture 2 is connected to the 100-liter water tank 17 through a working surface return water pipe 21.

[0038] Specifically, the bottom of the machine cabinet 1 is equipped with a first drain outlet 9 and a second drain outlet 10 for discharging wastewater from the equipment.

[0039] Specifically, the main unit cabinet 7 is equipped with an industrial control computer for controlling the testing machine. An indicator light 701 and a three-color alarm light 702 are installed on the top of the main unit cabinet 7. A touch screen 703 and a Bluetooth keyboard and mouse 704 are installed on the main unit cabinet 7 for controlling the industrial control computer.

[0040] In this embodiment, the industrial control computer inside the main unit cabinet 7 displays various information and parameters (such as pH value and vacuum value) through the touch screen 703, and can set test parameters. Users can call different programs according to different product models; or set the equipment to automatic mode and single-step mode. The single-step mode can perform step-by-step operation; it can set counting functions, total equipment output, output per shift, etc.; it can set IO alarm points to facilitate fault location; it can automatically record and display test parameters and results, and has remote data monitoring function to remotely monitor production.

[0041] Specifically, the information detected by components such as the liquid level sensor 22, pH meter 23, and gas source processor 8 will be displayed on the touch screen 703. When the value exceeds or falls below the alarm value set by the user, the touch screen 703 and the three-color alarm light on the main unit cabinet will issue an alarm to remind that an error has occurred.

[0042] In this embodiment, during testing, the movable protective door 3 and the movable telescopic top cover 4 are controlled by the button assembly 12 and opened electrically via the guide rail. The test valve to be tested is installed into the product fixing fixture 202. After the test valve is installed, the equipment is started and the safety protective door is closed. First, the vacuum pump 14 is started to evacuate the inside of the equipment. If the vacuum degree reaches the required level within the specified time, the vacuum valve is closed and the high-pressure water valve is opened to perform a water pressure test on the shell. If the vacuum degree does not reach the required level within the specified time, it indicates that there is a leak in the equipment. The alarm content is displayed in large red font on the industrial control computer touch screen 703, and the three-color alarm light 702 lights up red and emits an audible warning.

[0043] During the shell water pressure test, the stainless steel high-pressure water pump 15 and the pneumatic booster pump 25 of the water supply circuit component in the machine cabinet 1 are started, drawing water from the 100-liter water tank 17 into the pump body for pressurization. The water supply circuit structure is activated and high-pressure water is input into the test sealing fixture 201, which is also the shell of the test valve, through the water and air pressure common pipeline 19 to test the water pressure resistance of the test valve shell. The maximum pressure value of the water pressure test is designed to be 36 Bar. If the set pressure value is exceeded within the specified time during the shell water pressure test, it indicates that there is a leak in the shell. At this time, the equipment will issue an alarm, and the alarm content will be displayed in red on the touch screen 703. The three-color alarm light 702 will light up red and emit an audible warning. The indicator light 701 will also light up red, indicating that the shell water pressure test of the test valve is unqualified. If the pressure does not drop to the set value or does not drop at all, the shell water pressure test is considered qualified, and the indicator light 701 will light up green. After the test is completed, the water is transported back to the water tank through the working surface return water pipe 21 for recycling.

[0044] After the shell test is completed, the equipment automatically switches to the sealing test. The test valve is closed, and the solenoid valve connected to the laser bubble counter 6 at the exhaust end of the test valve body is opened. The water supply circuit structure is activated, and 6 kg of compressed gas is introduced into the test valve. The pressure is maintained for a set time. If the laser bubble counter 6 alarms, it means that gas is escaping from the valve seal and generating bubbles that are detected by the counter. This indicates a leak in the test valve, and the valve's sealing performance is deemed unqualified. Only test valves that pass both the shell water pressure test and the sealing test can be considered qualified. By using the testing machine to perform shell water pressure tests and sealing tests on the valves, the performance of the valves is tested, improving the overall quality of the product. The multiple detection and alarm mechanisms allow for timely detection and alarm alerts for problems, improving production efficiency. In addition, the water supply circuit structure allows for resource reuse, reducing resource waste and production costs.

[0045] Specifically, the front of the workbench is equipped with a movable protective door 3 that can be moved vertically and opened via a slide rail. The side and back of the workbench are fixedly connected to a fixed protective door 301. The top of the movable protective door 3 and the fixed protective door 301 are slidably connected to a movable telescopic top cover 4 via a telescopic door support rail 401.

[0046] Specifically, a blocking cylinder 5 is fixedly connected to the side of the fixed protective door 301.

[0047] Specifically, the back of the machine cabinet 1 is fixedly connected to an air source processor 8 and an aviation plug 11. The aviation plug 11 is electrically connected to the internal structure of the machine cabinet 1. The air source processor 8 is used to process the air source to ensure the quality of the air source.

[0048] Specifically, the front of the machine cabinet 1 is provided with a button assembly 12, which is used to control the opening or closing of the movable telescopic top cover 4 and the movable protective door 3, or to control the start or stop of the test.

[0049] In use, this utility model includes a reverse osmosis water purifier 18 installed inside the cabinet 1. External water is introduced into the reverse osmosis water purifier 18 through the inlet 24. After filtration and purification, the filtered water is introduced into a 100-liter water tank 17 through the filter inlet valve 16. When water needs to be supplied to the test fixture 2, the vacuum pump 14 inside the cabinet 1 creates a vacuum in the workbench space through the vacuum pipe 1401. The stainless steel high-pressure water pump 15 on the side of the 100-liter water tank 17 draws water from the tank and pressurizes it to generate high-pressure water. The valve between the air-pressure common pipeline 19 and the stainless steel high-pressure water pump 15 is opened, and the valve between the water-pressure and air-pressure common pipeline 19 and the pneumatic booster pump 25 is closed. High-pressure water is transported through the water-pressure and air-pressure common pipeline 19, through the workbench, and into the test valve body inside the test sealing fixture 201 for testing. After the test sealing fixture 201 completes the test of the test valve body, the industrial control computer automatically controls the opening of the valve on the working surface return water pipe 21. The working surface return water pipe 21 transports the tested water back into the water tank, thus forming a complete water supply circuit structure.
