Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and more specifically, to a valve pressure resistance test bench for processing. Background Technology

[0002] In the valve manufacturing process, pressure resistance is one of the key indicators for measuring valve quality. If a valve's pressure resistance is substandard, it is prone to leakage and damage in actual use, especially when conveying high-pressure fluids. This not only wastes resources but may also lead to safety accidents. For example, in the chemical industry, leaks of toxic and harmful fluids can pollute the environment and threaten human health, while in the energy sector, leaks of high-pressure gases can lead to explosions.

[0003] Traditional valve pressure testing equipment suffers from several structural design deficiencies. Some devices lack stable and efficient valve fixing mechanisms, making valves prone to displacement or even detachment during testing, affecting the accuracy and safety of the test. Other devices have pressure detection components that are not precise or intuitive enough, failing to promptly and clearly reflect valve performance changes under pressure, resulting in significant test result errors and failing to meet high-precision testing requirements. Furthermore, traditional equipment often involves cumbersome operation procedures and low testing efficiency, hindering large-scale valve production testing. Therefore, there is an urgent need for a well-structured, stable, accurate, and easy-to-operate valve pressure testing bench for manufacturing processes to ensure the reliability and efficiency of valve pressure performance testing, thereby improving the overall quality of valve products. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a valve pressure resistance test bench for processing that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a valve pressure resistance test bench for processing includes a support rod, a placement platform fixedly connected to the support rod, a test cylinder fixedly connected to the placement platform, a test rod slidably connected to the test cylinder, a hollow inner cavity opened in the test cylinder, the interior of the hollow inner cavity being in a vacuum state; a display block fixedly connected to the test rod, the test rod passing through the test cylinder and connected to the display block, a compression spring fixedly connected to the display block, and the test cylinder fixedly connected to the compression spring; the test cylinder is made of transparent material, and scale lines are set on the outer periphery of the test cylinder.

[0006] Furthermore, bases are symmetrically fixedly connected to the support rod for supporting the support rod.

[0007] Furthermore, a main gear is rotatably connected to the placement platform via bearings, and the main gear is driven by a built-in drive unit of the equipment.

[0008] Furthermore, a secondary gear meshes with the main gear, and a main shaft is fixedly connected to the secondary gear. The main shaft is hollow inside and has internal threads, and a clamp is threaded onto the main shaft.

[0009] Furthermore, a telescopic cylinder is fixedly connected to the support rod, and a telescopic rod is slidably connected to the output end of the telescopic cylinder. A pressing block is fixedly connected to the telescopic rod, and the pressing block corresponds to the clamp.

[0010] Furthermore, a vent valve is fixedly connected to the detection cylinder, and the vent valve corresponds to the hollow inner cavity.

[0011] Furthermore, the test cylinder fixed on the platform is made of transparent material with scale lines on the outside for easy observation. The hollow inner cavity of the test cylinder is in a vacuum state. The test rod is slidably connected to the test cylinder, and the display block on the test rod is connected to a compression spring, which is fixed to the test cylinder. When the valve is pressurized, if there are problems such as leakage in the valve, it will change the pressure environment around the test cylinder. Under the action of pressure difference, the test rod will overcome the elastic force of the compression spring and move. Through the transparent test cylinder and the scale lines on it, combined with the position change of the display block, the pressure-related data can be read intuitively, thereby judging whether the pressure resistance performance of the valve meets the requirements. In addition, the vent valve on the test cylinder can be used to depressurize the hollow inner cavity after the test, which is convenient for equipment reset and next use.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0013] 1. This utility model uses the meshing transmission of the main gear and the auxiliary gear to drive the clamp on the main shaft to move, which can adapt to the clamping requirements of valves of different sizes. Combined with the extrusion block driven by the telescopic cylinder, it forms a bidirectional fixation, which can effectively prevent the valve from shifting or falling off during the test, providing a stable basic condition for the test and reducing the test error caused by unstable fixation.

[0014] 2. This utility model uses a telescopic cylinder as the pressure source. By adjusting the working pressure of the cylinder, the force applied to the valve can be precisely controlled. It can accurately simulate various pressure environments of the valve in actual use, meet the testing requirements of valves with different pressure resistance levels, and improve the pertinence and reliability of the test.

[0015] 3. This utility model uses a transparent detection cylinder with surrounding scale lines to directly observe the displacement changes of the detection rod and display block. The mechanical movement caused by the pressure difference intuitively reflects the valve's pressure resistance performance, eliminating the need for complex data analysis. This allows operators to quickly determine whether the valve has a leak and its pressure resistance limit, thus improving detection efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] A base 2 is symmetrically fixedly connected to the support rod 1 to support the support rod 1.

[0027] The main gear 31 is rotatably connected to the placement platform 3 via bearings, and the main gear 31 is driven by the built-in drive device of the equipment.

[0028] A secondary gear 32 meshes with the main gear 31, and a main shaft 33 is fixedly connected to the secondary gear 32. The main shaft 33 is hollow inside and has threads inside. A clamp 34 is threadedly connected to the main shaft 33.

[0029] A telescopic cylinder 5 is fixedly connected to the support rod 1. A telescopic rod 51 is slidably connected to the output end of the telescopic cylinder 5. A pressing block 52 is fixedly connected to the telescopic rod 51. The pressing block 52 corresponds to the clamp 34.

[0030] A vent valve 45 is fixedly connected to the detection cylinder 41, and the vent valve 45 corresponds to the hollow inner cavity 44.

[0031] The test cylinder 41, fixed on the placement platform 3, is made of transparent material with scale lines on the outside for easy observation. The hollow inner cavity 44 inside the test cylinder 41 is in a vacuum state. The test rod 4 is slidably connected to the test cylinder 41. The display block 43 on the test rod 4 is connected to a compression spring 42, which is fixed to the test cylinder 41. When the valve is pressurized, if there are problems such as leakage, it will change the pressure environment around the test cylinder 41. Under the action of pressure difference, the test rod 4 will overcome the elastic force of the compression spring 42 and move. Through the transparent test cylinder 41 and the scale lines on it, combined with the position change of the display block 43, the pressure-related data can be read intuitively, thereby judging whether the pressure resistance performance of the valve meets the requirements. In addition, the vent valve 45 on the test cylinder 41 can be used to depressurize the hollow inner cavity 44 after the test, which is convenient for equipment reset and next use.

[0032] This invention utilizes the support rod 1 of the test bench for overall support, with the base 2 symmetrically fixed on the support rod 1 to further enhance support stability. The placement platform 3 is fixed on the support rod 1, and the main gear 31 on the placement platform 3 is rotatably connected to the bearing and driven to rotate by the built-in drive device of the equipment. The main gear 31 meshes with the secondary gear 32, driving the secondary gear 32 to rotate. The hollow main shaft 33 fixed on the secondary gear 32 rotates accordingly, thereby causing the clamp 34 threadedly connected to the main shaft 33 to move along the main shaft 33, realizing the clamping of valves of different sizes.

[0033] The telescopic cylinder 5 fixed on the support rod 1 serves as the pressure power source. The telescopic rod 51 connected to its output end can slide axially. The squeezing block 52 at the end of the telescopic rod 51 corresponds to the position of the clamp 34. After the valve is initially fixed by the clamp 34, the telescopic cylinder 5 is activated, driving the telescopic rod 51 to extend forward and causing the squeezing block 52 to apply axial pressure to the valve. By controlling the working pressure of the telescopic cylinder 5, the magnitude of the applied force to the valve can be precisely adjusted, simulating the pressure environment that the valve experiences in actual working conditions, and providing controllable pressure conditions for pressure resistance testing.

[0034] The test cylinder 41, fixed on the placement platform 3, is made of transparent material with scale lines on the outside for easy observation. The hollow inner cavity 44 inside the test cylinder 41 is in a vacuum state. The test rod 4 is slidably connected to the test cylinder 41. The display block 43 on the test rod 4 is connected to a compression spring 42, which is fixed to the test cylinder 41. When the valve is pressurized, if there are problems such as leakage, it will change the pressure environment around the test cylinder 41. Under the action of pressure difference, the test rod 4 will overcome the elastic force of the compression spring 42 and move. Through the transparent test cylinder 41 and the scale lines on it, combined with the position change of the display block 43, the pressure-related data can be read intuitively, thereby judging whether the pressure resistance performance of the valve meets the requirements. In addition, the vent valve 45 on the test cylinder 41 can be used to depressurize the hollow inner cavity 44 after the test, which is convenient for equipment reset and next use.
