Description

Technical Field

[0001] This application relates to the field of testing equipment technology, specifically a multifunctional pressure testing bench. Background Technology

[0002] In boiler system operation, the water level gauge serves as a critical safety monitoring device, primarily used to display the real-time water level status inside the boiler and ensure the system operates within a safe range. Water level gauges typically employ transparent glass tubes or electronic sensors, measuring water level through the principle of communicating vessels or pressure difference. Their accuracy directly impacts the boiler's thermal efficiency, equipment lifespan, and operational safety.

[0003] Due to the structural characteristics of water level gauges, they require frequent maintenance. Sometimes, internal components need to be repaired and replaced. After maintenance and repair, water level gauges need to pass a water pressure test before they can be reinstalled and used again. However, existing technology lacks the corresponding special equipment to test water level gauges. Usually, only simple pressure gauges are used for testing, which is inconvenient to use.

[0004] Therefore, this application provides a multifunctional pressure testing bench to solve the above problems. Utility Model Content

[0005] This application provides a multifunctional pressure testing bench, which aims to solve the problems mentioned in the background art, such as the lack of corresponding dedicated equipment for testing water level gauges.

[0006] To achieve the above objectives, this application provides the following technical solution: a multifunctional pressure testing bench, comprising an operating table and a water flow testing mechanism fixedly installed on the operating table.

[0007] The water flow testing mechanism includes a high-pressure water cylinder fixedly installed on an operating table. A water supply pipe is fixedly installed at one end of the high-pressure water cylinder, and a pressure pump connected to an external water source is fixedly installed on the water supply pipe. A flushing pipe is fixedly installed at the other end of the high-pressure water cylinder, and a first flange for connecting a boiler water level gauge is fixedly installed at the end of the flushing pipe away from the high-pressure water cylinder. A pressure gauge is fixedly installed on the high-pressure water cylinder. In use, the pressure pump is connected to an external water source such as a faucet. Then, the water inlet of the boiler water level gauge to be tested is fixed to the first flange, and the air inlet of the boiler water level gauge is sealed. The pressure pump is started, pressurizing the water flow through the water supply pipe and drawing it into the high-pressure water cylinder. The water in the high-pressure water cylinder flows into the boiler water level gauge through the flushing pipe. The pressure pump is continuously adjusted, and the water pressure is monitored in real time using the pressure gauge, thus completing the test on the boiler water level gauge. This method is convenient and quick to use.

[0008] Preferably, in order to clean the experimental water, a water tank is provided on the operating table, and the high-pressure water cylinder is fixedly installed in the water tank, so that the discharged water flows directly into the water tank for easy collection and cleaning.

[0009] Preferably, in order to release pressure, a drain pipe is fixedly installed at the bottom of the outer wall of the high-pressure water cylinder, and a drain valve is fixedly installed on the drain pipe to complete the pressure release and water discharge, which is convenient and quick.

[0010] Preferably, to support the boiler water level gauge, the test bench also includes a support mechanism. The support mechanism includes a column fixedly installed on the operating platform near the first flange. A groove is provided in the column, and a screw is rotatably installed in the groove. One end of the screw passes through the groove and a knob is fixedly installed at the end. An extension rod adapted to the groove is screwed onto the screw. A second flange located on the same vertical axis as the first flange is fixedly installed on the extension rod, so as to adjust according to different specifications of boiler water level gauges, facilitate fixation, stabilize the boiler water level gauge, and improve test stability.

[0011] Preferably, for fixation, both the first and second flanges are provided with long slots arranged in a circumferential array, and the position of the adjusting bolts is adjusted within the long slots to improve the adaptability of the device.

[0012] This test bench connects a pressure pump to an external water source such as a faucet. The water inlet of the boiler water level gauge to be tested is then fixed to the first flange, and the air inlet of the boiler water level gauge is sealed. The pressure pump is then started, pressurizing the water flow through the water pipe and drawing it into a high-pressure water tank. The water in the high-pressure water tank flows through a flushing pipe into the boiler water level gauge. The pressure pump is continuously adjusted, and the pressure gauge continuously monitors the water pressure, thus completing the experiment on the boiler water level gauge. It is convenient and quick to use.

[0013] After fixing the water inlet of the boiler water level gauge to the first flange, the knob is turned. The knob drives the screw to rotate, and the screw drives the extension rod to move up and down in the slide groove, thereby adjusting the distance between the second flange and the first flange. This allows for adjustment according to different specifications of boiler water level gauges, facilitates fixing and stabilizing the boiler water level gauge, and improves test stability.

[0020] 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, and 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.

[0021] Example 1

[0022] This embodiment provides a multifunctional pressure testing bench, such as Figure 1-4 As shown, the test bench includes an operating platform 1 and a water flow testing mechanism 2 fixedly installed on the operating platform 1.

[0023] The water flow test mechanism 2 includes a high-pressure water cylinder 21 fixedly installed on the operating table 1. A water supply pipe 22 is fixedly installed at one end of the high-pressure water cylinder 21. A booster pump 23 connected to an external water source is fixedly installed on the water supply pipe 22. A flushing pipe 24 is fixedly installed at the other end of the high-pressure water cylinder 21. A first flange 25 for connecting to a boiler water level gauge is fixedly installed at the end of the flushing pipe 24 away from the high-pressure water cylinder 21. A pressure gauge 26 is fixedly installed on the high-pressure water cylinder 21.

[0024] In use, connect the booster pump 23 to an external water source such as a faucet, then fix the water inlet of the boiler water level gauge to be tested to the first flange 25, and seal the air inlet of the boiler water level gauge. Start the booster pump 23 to pressurize the water flow through the water pipe 22 and pump it into the high-pressure water tank 21. The water flow in the high-pressure water tank 21 enters the boiler water level gauge through the flushing pipe 24. Continue to adjust the booster pump 23, and observe the water pressure in real time with the pressure gauge 26, thereby completing the experiment on the boiler water level gauge. It is convenient and quick to use.

[0025] Specifically, a water tank 27 is provided on the control panel 1, and a high-pressure water cylinder 21 is fixedly installed in the water tank 27. During use, after testing the boiler water level gauge, the test water in the high-pressure water cylinder 21 needs to be discharged. The discharged water flows directly into the water tank 27 for easy collection and cleaning.

[0026] More specifically, a drain pipe 28 is fixedly installed at the bottom of the outer wall of the high-pressure water cylinder 21, and a drain valve 29 is fixedly installed on the drain pipe 28. In use, when the pressure gauge 26 shows that the pressure of the filter water level gauge has reached the threshold, the pressurization pump 23 is turned off, the drain valve 29 is opened, and the water in the high-pressure water cylinder 21 and the boiler water level gauge is discharged into the water tank 27 through the drain pipe 28, completing the pressure relief and water discharge, which is convenient and quick.

[0027] Example 2

[0028] Unlike Embodiment 1, when pressurizing the boiler water level gauge, it may shake due to excessive pressure. Also, the specifications of the boiler water level gauges for various tests are different, making them inconvenient to fix. Therefore, the test bench also includes a support mechanism 3. The support mechanism 3 includes a column 31 fixedly installed on the operating table 1 near the first flange 25. A groove 32 is opened in the column 31. A screw 33 is rotatably installed in the groove 32. One end of the screw 33 passes through the groove 32 and a knob 34 is fixedly installed at the end. An extension rod 35 adapted to the groove 32 is screwed onto the screw 33. A second flange 36 located on the same vertical axis as the first flange 25 is fixedly installed on the extension rod 35.

[0029] In use, after fixing the water inlet of the boiler water level gauge to the first flange 25, turn the knob 34. The knob 34 drives the screw 33 to rotate, and the screw 33 drives the extension rod 35 to move up and down in the slide groove 32, thereby adjusting the distance between the second flange 36 and the first flange 25. This allows for adjustment according to different specifications of boiler water level gauges, facilitates fixing, stabilizes the boiler water level gauge, and improves test stability.

[0030] Specifically, both the first flange 25 and the second flange 36 have elongated slots 37 arranged in a circumferential array. In use, the boiler water level gauge is connected to the first flange 25 and the second flange 36 by bolts. The position of the bolts is adjusted within the elongated slots 37 according to the specifications of different boiler water level gauges to improve the adaptability of the device.

[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
