Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to an automated T-type product anti-backflow valve performance testing frame. Background Technology

[0002] Anti-backflow valves are widely used in connecting pipelines to prevent liquid backflow. Existing anti-backflow valves typically include a valve body and a valve disc rotatably mounted inside the valve body. The valve disc rotates relative to the valve body to control the opening and closing of the fluid passage inside the valve body.

[0003] Traditional T-type products do not undergo post-assembly testing for backflow prevention valve performance, so product performance cannot be guaranteed. Backflow prevention valve performance can only be tested by the supplier before the materials are directly assembled and delivered to the end user. Problems with the backflow prevention valve performance can only be discovered during product use. Summary of the Invention

[0004] The purpose of this invention is to provide an automated T-type product anti-backflow valve performance testing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated T-type product anti-backflow valve performance test frame, including a test frame, a cylinder frame fixedly installed at the top center of the test frame, a downward cylinder fixedly installed on one side of the cylinder frame, a rear cylinder fixedly installed on the top of the test frame on the rear side of the cylinder frame, and side cylinders fixedly installed on the top of the test frame on both sides of the cylinder frame.

[0006] A pressure plate is fixedly installed at the output end of the pressure cylinder, a rear baffle is fixedly installed at the output end of the rear cylinder, and a side baffle is fixedly installed at the output end of the side cylinder. The product to be tested is placed between the pressure plate, the rear baffle, and the two side baffles.

[0007] Preferably, two start switches and a buzzer are installed on one side of the test rack, and an indicator light is installed on the side of the buzzer on the test rack.

[0008] Preferably, a door opening is provided on one side of the cylinder frame, and the rear baffle passes through the door opening.

[0009] Preferably, a sealing plate is installed on the rear baffle and the two side baffles, and the sealing plate is adapted to the channel of the product to be tested.

[0010] Preferably, the test frame has a bottom mold on top, and the product to be tested is placed on the bottom mold.

[0011] Preferably, pressure sensors are installed on both sides of the channel of the product under test.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] It facilitates the limiting and fixing of the product under test, and facilitates the positioning and sealing of the channel of the T-type product under test, thereby improving the accuracy of the test. It has a high degree of automation, is easy to operate, and avoids the failure to detect the performance of the anti-backflow valve during manual assembly, thus preventing unqualified products from reaching the end user.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an automated T-type product anti-backflow valve performance test frame, including a test frame 1, a cylinder frame 4 fixedly installed at the top center of the test frame 1, a downward cylinder 5 fixedly installed on one side of the cylinder frame 4, a rear cylinder 6 fixedly installed on the top of the test frame 1 on the rear side of the cylinder frame 4, and a side cylinder 7 fixedly installed on the top of the test frame 1 on both sides of the cylinder frame 4.

[0021] A pressure plate 8 is fixedly installed at the output end of the pressure cylinder 5, a rear baffle 9 is fixedly installed at the output end of the rear cylinder 6, and a side baffle is fixedly installed at the output end of the side cylinder 7. The product to be tested is placed between the pressure plate 8, the rear baffle 9 and the two side baffles.

[0022] In this utility model, two start switches 2 and a buzzer 3 are installed on one side of the test rack 1, and an indicator light is installed on the side of the buzzer 3 on the test rack 1.

[0023] In this utility model, a door opening is provided on one side of the cylinder frame 4, and the rear baffle 9 passes through the door opening, so that the rear baffle 9 passes through the cylinder frame 4 to seal the channel of the product to be tested.

[0024] In this invention, sealing plates are installed on the rear baffle 9 and the two side baffles, and the sealing plates are adapted to the channel of the product to be tested, so as to facilitate sealing the channel of the product to be tested through the sealing plates.

[0025] In this utility model, a bottom mold is provided on the top of the test frame 1, and the product to be tested is placed on the bottom mold. The bottom mold fits the product to be tested, which facilitates the installation and fixation of the product to be tested.

[0026] In this invention, pressure sensors are installed on both sides of the channel of the product under test to determine whether the air pressure on both sides of the anti-backflow valve is consistent.

[0027] The implementation steps of this utility model are as follows:

[0028] 1. Turn on the power switch;

[0029] 2. After placing the product to be tested into the bottom mold, press the start button switch 2;

[0030] 3. The program controls the downward pressure cylinder 5, which presses down the product to be tested through the pressure plate 8;

[0031] 4. The program controls the rear cylinder 6 to extend through the rear baffle 9 to block the middle channel of the T-shaped product. At the same time, the side baffles of the side cylinders 7 on both sides will also extend under the control of the program to block the channels on both sides of the anti-backflow valve of the T-shaped product for testing.

[0032] 5. The program-controlled test channel is the forward performance test channel for the anti-backflow valve. Air is then introduced for testing. The program determines whether the forward performance of the anti-backflow valve is qualified based on whether the air pressure on both sides of the anti-backflow valve is consistent. If the air pressure on both sides is consistent, the forward performance of the anti-backflow valve is qualified; otherwise, it is unqualified. If the forward performance of the anti-backflow valve is qualified, the program proceeds to the reverse performance test. If the forward performance of the anti-backflow valve is unqualified, the program ends, all cylinders return to their initial state, the indicator light illuminates red, the buzzer sounds an alarm, and the unqualified product is manually removed from the bottom mold for isolation and subsequent replacement of the anti-backflow valve.

[0033] 6. The program controls the shutdown of the test air pressure and releases the residual air pressure inside the product. Then, it switches the test channel to the anti-backflow valve reverse performance test channel and re-energizes the product for testing. The program judges whether the anti-backflow valve's reverse performance is qualified based on whether the air pressure on both sides of the anti-backflow valve is consistent. If the supplied air pressure is greater than the air pressure on the other side of the anti-backflow valve, it is qualified; otherwise, the anti-backflow valve's reverse performance is unqualified. If the anti-backflow valve's reverse performance is qualified, the indicator light will be green, and the buzzer will not sound an alarm. The anti-backflow valve performance test is complete, all cylinders return to their initial state, and qualified products are manually removed from the bottom mold to proceed to the next assembly process. If the anti-backflow valve's reverse performance is unqualified, the indicator light will be red, the buzzer will sound an alarm, and unqualified products are manually removed from the bottom mold for isolation and subsequent replacement of the anti-backflow valve.

[0034] 7. Repeat the previous steps.
