Description

Technical Field

[0001] This utility model relates to the field of safety valve testing technology, and in particular to a device for testing the self-closing durability performance of a safety valve. Background Technology

[0002] A safety valve is a special valve that is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, it releases the medium to the outside of the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves belong to the category of automatic valves and are mainly used in boilers, pressure vessels, and pipelines to control the pressure to not exceed the specified value. They play an important role in protecting personal safety and equipment operation. Safety valves require alignment and testing after production.

[0003] In the field of safety valve testing technology, most existing safety valve testing equipment is only used to test whether the safety valve is qualified, and it is not convenient to test its durability.

[0004] Therefore, it is necessary to provide a device for testing the self-closing durability of safety valves to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a device for testing the self-closing durability of safety valves, which solves the problem that most existing safety valve testing devices only test whether the safety valve is qualified and are not convenient for testing its overall durability.

[0006] To solve the above-mentioned technical problems, this utility model provides a safety valve self-closing durability performance testing device, comprising: a base;

[0007] The base has a vertical tube inside, and a pneumatic pump is installed inside the base. A pressure pipe is installed at the output end of the pneumatic pump and is fixedly connected to the vertical tube. A pressure detector is installed on the periphery of the vertical tube, and a wire is installed on the left side of the pressure detector. A display panel is installed on the front of the base, and the wire is electrically connected to the display panel. A bracket is fixedly connected to the upper end of the base, and a telescopic cylinder is installed on the upper end of the bracket. A pressure cap is fixedly connected to the output end of the telescopic cylinder.

[0008] Preferably, the bottom of the pressure cap has a notch, and multiple sets of notches are provided; a rubber ring is fixedly connected to the upper end of the vertical tube.

[0009] Preferably, the base is provided with casters at the bottom, and four sets of casters are provided.

[0010] Preferably, the bottom of the base is threaded with a lead screw, and four sets of lead screws are provided.

[0011] Preferably, a base plate is rotatably connected to the bottom end of the lead screw, and a limiting plate is fixedly connected to the bottom end of the lead screw, with the limiting plate rotatably connected inside the base plate.

[0012] Preferably, an anti-slip pad is fixedly connected to the bottom of the substrate, and a rotating block is fixedly connected to the upper end of the lead screw.

[0013] Compared with related technologies, the self-closing durability testing device for safety valves provided by this utility model has the following beneficial effects:

[0014] This invention provides a device for testing the self-closing durability of a safety valve. The safety valve is placed at the top of a vertical pipe. A telescopic cylinder moves the pressure cap downwards to press the safety valve shut. A pneumatic pump then pressurizes the vertical pipe. When the internal pressure is too high, the safety valve automatically releases pressure. The pressure value inside the vertical pipe can be observed on a display panel. Continuous pressurization of the vertical pipe causes the safety valve to continuously release pressure, thus testing its durability. This structure facilitates the testing of the safety valve's durability. The universal casters allow for easy adjustment of the base's position. After adjustment, rotating the pivot block moves the lead screw downwards along the base, causing the base plate to move downwards simultaneously. Once the anti-slip pad is firmly in contact with the bottom table or ground, the base is positioned, preventing movement. This structure makes the base easy to move and position, and is very user-friendly. Attached Figure Description

Figure 3 for Figure 1 The schematic diagram of the bottom part of the lead screw shown is a self-closing durability testing device for a safety valve, including: a base 1;

[0021] The base 1 has a vertical tube 2 inside, and a pneumatic pump 3 inside the base 1. The output end of the pneumatic pump 3 has a pressure pipe 4, which is fixedly connected to the vertical tube 2. A pressure detector 5 is installed on the side of the vertical tube 2. A wire 6 is installed on the left side of the pressure detector 5. A display panel 7 is installed on the front of the base 1. The wire 6 is electrically connected to the display panel 7. A bracket 8 is fixedly connected to the upper end of the base 1. A telescopic cylinder 9 is installed on the upper end of the bracket 8. A pressure cap 10 is fixedly connected to the output end of the telescopic cylinder 9. The object between the pressure cap 10 and the rubber ring 12 is the body of the safety valve.

[0022] The bottom of the pressure cap 10 has a notch 11, and there are multiple sets of notches 11. A rubber ring 12 is fixedly connected to the upper end of the vertical pipe 2. The notch 11 facilitates the discharge of gas, and the rubber ring 12 helps to maintain a good seal between the safety valve and the vertical pipe 2.

[0023] The base 1 has four sets of casters 13 at its bottom.

[0024] The bottom of the base 1 is threaded with a lead screw 14, and there are four sets of lead screws 14.

[0025] The bottom end of the lead screw 14 is rotatably connected to the base plate 15, and the bottom end of the lead screw 14 is fixedly connected to the limiting plate 16, which is rotatably connected inside the base plate 15.

[0027] The working principle of the safety valve self-closing durability testing device provided by this utility model is as follows:

[0028] Step 1: When in use, place the safety valve at the upper end of the vertical pipe 2. The pressure cap 10 can be moved downward by the telescopic cylinder 9 to press the safety valve. At this time, the air pump 3 pressurizes the inside of the vertical pipe 2. When the pressure inside the vertical pipe 2 is too high, the safety valve will automatically release pressure. At the same time, the pressure value inside the vertical pipe 2 can be observed through the display panel 7. By continuously pressurizing the inside of the vertical pipe 2, the safety valve under test can be continuously operated to release pressure, thereby testing the durability of the safety valve.

[0029] Step 2: The position of the base 1 can be easily adjusted by the casters 13. After the position is adjusted, the screw 14 can be moved downward along the base 1 by rotating the swivel block 18. At this time, the bottom plate 15 moves downward in sync. When the anti-slip pad 17 is in close contact with the bottom table or ground, the base 1 can be positioned so that the base 1 is not easy to move.

[0030] Compared with related technologies, the self-closing durability testing device for safety valves provided by this utility model has the following beneficial effects:

[0031] The safety valve is placed at the top of the vertical pipe 2. The pressure cap 10 is moved downward by the telescopic cylinder 9 to press the safety valve. At this time, the air pump 3 pressurizes the inside of the vertical pipe 2. When the pressure inside the vertical pipe 2 is too high, the safety valve will automatically release pressure. The pressure value inside the vertical pipe 2 can be observed through the display panel 7. By continuously pressurizing the inside of the vertical pipe 2, the safety valve under test can be continuously operated to release pressure, thereby testing the durability of the safety valve. This structure is very convenient for testing the durability of the safety valve. The position of the base 1 can be easily adjusted by the caster wheel 13. After the position is adjusted, the screw 14 can be moved downward along the base 1 by rotating the rotating block 18. At this time, the bottom plate 15 moves downward simultaneously. When the anti-slip pad 17 is in close contact with the bottom table or ground, the base 1 can be positioned, making it difficult to move the base 1. This structure is very convenient for moving and positioning the base 1, and is very convenient to use.
