Technical Field

[0001] This utility model relates to the field of valve testing technology, specifically a valve pressure testing machine. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. The core purpose of pressure testing valves is to check their sealing performance and strength, ensuring that they can work reliably under various operating conditions, thereby guaranteeing the smooth operation of the process and production safety.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4As shown, the valve pressure testing machine of this embodiment includes a base 1, with a water storage chamber 2 inside the base 1 for storing water, and the water inside the water storage chamber 2 can be recycled. A placement groove 3 is provided on the upper end of the base 1, and a fixing frame 4 is installed on the upper end of the base 1 above the placement groove 3. An electric push rod 5 is installed on the upper end of the fixing frame 4, and a pressure plate 6 is installed at the output end of the electric push rod 5. Sealing gaskets 7 are installed at the lower end of the pressure plate 6 and the bottom end of the placement groove 3. An air pipe 8 is installed at the bottom end of the placement groove 3. An air pump 9 is installed at one end of the base 1, and the air pump 9 is connected to one end of the air pipe 8. A transparent cover 10 is detachably and movably installed on the pressure plate 6, and a water injection pipe 11 is installed on the transparent cover 10. The valve pressure testing machine is tested by... The valve is placed inside the placement slot 3, and the electric push rod 5 is controlled to move the pressure plate 6 downward. The sealing gasket 7 can seal both ends of the valve. At the same time, the lower end of the transparent cover 10 contacts the sealing gasket 7. Water is injected into the transparent cover 10 through the water injection pipe 11. By observing whether bubbles are generated in the water, the sealing performance of the valve can be tested during the pressure test. This method is convenient to observe and does not require detailed observation to understand the valve sealing performance test. A pressure test plate 12 is movably installed on the base 1 on one side of the placement slot 3. By moving the pressure test plate 12 and placing the valve on the pressure test plate 12, the pressure plate 6 is used to press the valve, which can test the valve's compressive strength. This method has multiple pressure testing functions.

[0022] Specifically, a pump 13 is installed at one end of the base 1 below the air pump 9. The pump 13 is connected to the water storage chamber 2 through a pipe. The water injection pipe 11 is connected to the output end of the pump 13. The water injection pipe 11 is a flexible hose. By starting the pump 13, the pump 13 injects the water inside the water storage chamber 2 into the transparent cover 10 through the water injection pipe 11, which makes it easy to detect whether the valve sealing has leaked and the location of the leak.

[0023] Furthermore, a water trough 14 is provided at the bottom of the placement groove 3 outside the sealing gasket 7, and several seepage holes 15 are provided at the bottom of the water trough 14. The seepage holes 15 are connected to the water storage cavity 2. Water used inside the transparent cover 10 can flow back into the water storage cavity 2 through the water trough 14 and the seepage holes 15, which facilitates the recycling of water inside the water storage cavity 2.

[0024] Furthermore, L-shaped plates 16 are installed on both sides of the upper end of the pressure plate 6. Guide rods 17 are installed on the upper end of the L-shaped plates 16 through through holes. The upper end of the guide rods 17 passes through the fixing frame 4 through through holes. Mounting plates 18 are installed on the lower end of the fixing frame 4. Elastic springs 19 are installed on the surface of the guide rods 17 between the mounting plates 18 and the L-shaped plates 16. The transparent cover 10 is detachably installed on the two mounting plates 18. Contact grooves 20 are provided on the lower sealing gasket 7. When the sealing gasket 7 on the pressure plate 6 comes into contact with the valve, a seal is formed between the lower end of the transparent cover 10 and the lower sealing gasket 7. The transparent cover 10 compresses the elastic springs 19 to keep the transparent cover 10 in contact with the sealing gasket 7 under a certain pressure.

[0025] Furthermore, connecting plates 21 are installed on both sides of the transparent cover 10. The connecting plates 21 are installed on the mounting plate 18 by bolts 22. The height of the transparent cover 10 can be changed according to the length of the test valve. The water injection pipe 11 is installed by thread. When performing pressure testing, the sealing gasket 7 on the transparent cover 10 and the pressure plate 6 can be removed to avoid damage to the transparent cover 10.

[0026] Furthermore, slide rails 23 are installed on the upper ends of the base 1 at both the front and rear of the placement slot 3. Slider 24 is movably mounted on the slide rails 23. Movable plates 25 are installed on the upper ends of the two sliders 24. Four pressure sensors 26 are mounted in a rectangular array on the upper end of the movable plates 25. A pressure test plate 12 is mounted on the four pressure sensors 26. A display screen 27 is installed on one end of the movable plate 25. The movable plate 25 can change its position by sliding. When the pressure plate 6 presses the valve surface, the pressure generated by the pressure plate 6 presses the pressure sensors 26 through the pressure test plate 12 and displays the pressure value on the display screen 27 for easy understanding of the applied pressure value. The pressure sensor 26 is model PC10. As for how the pressure detected by the pressure sensor 26 is converted into a digital display, it is known existing technology and will not be described in detail.

[0027] The usage method of this embodiment is as follows: When performing a sealing test during a pressure test, the valve is placed inside the placement groove 3, and the electric push rod 5 is controlled to move the pressure plate 6 downward. The sealing gasket 7 can seal both ends of the valve. At the same time, the lower end of the transparent cover 10 contacts the sealing gasket 7 and forms a seal. Simultaneously, the extraction pump 13 draws water from the water storage chamber 2 into the transparent cover 10. As the air pump 9 injects gas into the water valve through the air pipe 8, it is observed whether bubbles are generated on the surface of the water valve. The sealing performance of the water valve during the pressure test can be measured. After use, the pressure plate 6 is controlled to rise, and the water inside the transparent cover 10 falls into the water storage chamber 2 through the seepage hole 15. The water can be reused multiple times. When performing a pressure strength test, the pressure test plate 12 is moved to be below the pressure plate 6, and the valve is placed on the pressure test plate 12. The pressure plate 6 is used to press the valve, which can test the pressure resistance of the valve. The applied pressure value is displayed on the display screen 27 for easy understanding of the applied pressure value. This realizes the measurement of the valve's pressure resistance and has multiple pressure testing functions.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
