Description

Technical Field

[0001] The utility model relates to the field of corrosion-resistant flat valve testing, and more particularly to a corrosion-resistant flat valve testing platform. Background Art

[0002] A corrosion-resistant flat plate valve is a type of flat plate valve with excellent corrosion resistance. It is commonly used in pipeline systems that transport corrosive media. Its main structure usually includes the flat plate valve body, handwheel, valve stem, gate, and other components. To enhance corrosion resistance, the various components of the flat plate valve are generally manufactured from sulfur-resistant and corrosion-resistant materials.

[0003] After the production of corrosion-resistant flat plate valves is completed, they need to be tested on a test bench for their corrosion resistance. The main purpose is to test whether the sealing performance of the flat plate valve is affected when passing different corrosive liquids (or the same corrosive liquid at different flow rates), whether the valve body and internal structure are damaged, etc. However, existing test benches usually need to be equipped with high-precision detection instruments and control systems to accurately monitor and control the flow rate, temperature and other parameters of the corrosive liquid, and also require complex pipelines to enable it to transport different corrosive solutions to test the corrosion-resistant flat plate, which increases the total cost of the test bench. Its price may be tens of thousands of yuan or even higher, which is not conducive to the use of medium and small factories.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a corrosion-resistant flat valve test bench. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a corrosion-resistant flat valve test bench.

The utility model can drive the horizontal plate to move up and down by the hydraulic jack, and finally drive the solution collection box to move up and down, so as to adjust the height of the solution collection box, so that the recovery container can be placed under the drain pipe to collect the discharged corrosive solution. At the same time, when adding solution to the solution collection box, the height of the solution collection box can be appropriately lowered to leave enough operating space, which is more conducive to the staff to perform liquid adding operations.

[0023] like Figure 1-3 As shown, the utility model provides a corrosion-resistant flat valve test bench, including a support platform 1, a solution collection box 2 is provided at the bottom end of the support platform 1, and a liquid outlet pipe 3 equipped with a valve is provided on one side of the solution collection box 2, a metering pump 4 is installed at the head of the liquid outlet pipe 3, and a hose A5 is interconnected at the head of the metering pump 4, a liquid inlet pipe 6 is fixedly connected to the top of the support platform 1, and a hose B7 is interconnected at the top of the liquid inlet pipe 6, and through grooves 8 for the hose A5 and the hose B7 to pass through are provided on both sides of the top of the support platform 1, and the heads of the hoses A5 and B7 are provided with connecting pipes 9 that are detachably connected to the corrosion-resistant flat valve, and a flange 18 is installed on the connecting pipe 9, which is sealed with the corrosion-resistant flat valve (the corrosion-resistant flat valve is equipped with a flange 18 corresponding to the flange 18 on the connecting pipe 9) through the flange 18.

[0024] During use, the corrosion-resistant flat valve is fixed to the top of the support platform 1. Then, the hoses A5 and B7 are connected to the metering pump 4 through the flange 18 on the connecting pipe 9 and sealed. Then, the corrosive solution for testing is added to the solution collection tank 2. The metering pump 4 and the valve on the liquid outlet pipe 3 are then opened to discharge the corrosive solution from the solution collection tank 2. The corrosive solution passes through the hose A5, the interior of the corrosion-resistant flat valve, the hose B7, and finally enters the solution collection tank 2, thus circulating. During this process, the metering pump 4 can accurately control the liquid flow rate, thereby testing the effects of the same solution on the corrosion-resistant flat valve at different flow rates. (After testing, the corrosion-resistant flat valve is disassembled and the interior is observed to obtain test data.) After testing one corrosive solution, the corrosive solution in the solution collection tank 2 can be replaced to test the next corrosive solution. This eliminates the need for high-precision equipment, control systems, and complex piping, while still providing basic corrosion testing capabilities for corrosion-resistant flat valves. The cost is low and the device is suitable for use in medium and small factories.

[0025] Furthermore, the top of the solution collection box 2 is threadedly connected to a top cover 11, and a drain pipe 12 equipped with a valve is provided at the center of the bottom end of the solution collection box 2. When adding the solution, open the top cover 11 and add the solution directly into the solution collection box 2. When taking out the solution, just open the valve on the drain pipe 12 to discharge the corrosion-resistant solution through the drain pipe 12. The operation is relatively simple. It should be noted that after a corrosive solution is discharged, clean water needs to be added to the solution collection box 2, and the clean water is allowed to flow through the hose A5, hose B7, corrosion-resistant flat valve and solution collection box 2 through the metering pump 4, so as to clean them to improve the accuracy of the test, and finally the cleaned waste water is discharged from the drain pipe 12.

[0026] In addition, a fixing assembly 10 for fixing the corrosion-resistant flat valve is installed at the middle part of the top of the support platform 1. In this way, the corrosion-resistant flat valve can be fixed during testing to prevent it from shifting and affecting the test results. The following is the specific structure of the fixing assembly 10: the fixing assembly 10 includes a fixing platform 1001 fixed to the middle part of the top of the support platform 1, and vertical plates 1002 are fixedly connected to the front and back sides of the top of the fixing platform 1001. Electric hydraulic rods 1003 are installed on the opposite surfaces of the vertical plates 1002. The head of the electric hydraulic rod 1003 is fixedly connected to a clamp. The tightening plate 1004 and the top center of the fixed platform 1001 are fixedly connected to the limiting block 1005. First, insert the bottom of the corrosion-resistant flat valve into the limiting block 1005 for limiting (the limiting block 1005 and the bottom of the corrosion-resistant flat valve are designed to correspond). When in use, the controller controls the two electric hydraulic rods 1003 to drive the two clamping plates 1004 to move to the middle position, and clamp the electric hydraulic rods 1003. The design of the limiting block 1005 makes it easy to fix the corrosion-resistant flat valve in a suitable position, thereby facilitating the later connection with the hose A5 and the hose B7.

[0027] The bottom end of the support platform 1 is fixedly connected to support plates 13 on both sides, the bottom end of the support plate 13 is fixedly connected to a base 14, the solution collection box 2 is installed on the base 14, and a telescopic rod 15 is fixedly connected between the solution collection box 2 and the base 14. There are four telescopic rods 15, which are distributed at the four corners of the solution collection box 2. A horizontal plate 16 is fixedly connected to one side of the base 14, and a hydraulic jack 17 is fixedly connected between the horizontal plate 16 and the base 14.

[0028] In this way, the hydraulic jack 17 can be used to drive the cross plate 16 to move up and down, and finally drive the solution collection box 2 to move up and down, so as to adjust the height of the solution collection box 2, so that the recovery container can be placed under the drain pipe 12 to collect the discharged corrosive solution (adjust the height so that the recovery solution is at an appropriate distance from the drain pipe 12 to avoid splashing). At the same time, when adding solution to the solution collection box 2, the height of the solution collection box 2 can be appropriately lowered to leave enough operating space, which is more conducive to the staff to perform liquid adding operations. When the solution collection box 2 moves up and down, the telescopic rod 15 will follow and extend to maintain the straight line movement of the solution collection box 2, so as to avoid the solution collection box 2 being affected by gravity and tilting, which eventually causes deformation of the connection between the cross plate 16 and the hydraulic jack 17.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
