Description

Technical Field

[0001] This utility model relates to the field of valve testing technology, and more specifically, to a valve testing device for pipeline valve processing. Background Technology

[0002] Pipeline valves play a vital role in industrial production, and their quality directly affects the safety and reliability of the entire system. Therefore, it is essential to conduct rigorous testing on valves during the manufacturing process. Valve testing devices are specialized equipment used to perform performance tests on various types of valves to ensure that they can operate reliably under actual working conditions.

[0003] However, when valve testing devices perform liquid testing, they can easily leave liquid residue on the inner wall of the pipeline valve, which can easily damage the inner wall of the pipeline valve. At the same time, valve testing devices used for pipeline valve processing cannot be adjusted according to the size of different pipeline valves when fixed, resulting in poor sealing of the pipeline valve during testing and affecting the testing effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a valve testing device for pipeline valve processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A valve testing device for pipeline valve processing includes a testing platform, a placement mechanism on top of the testing platform, an auxiliary mechanism one on top of the testing platform, a testing mechanism connected to one side of the auxiliary mechanism one, and an auxiliary mechanism two connected to one end of the testing mechanism. The auxiliary mechanism two includes a delivery pipe connected to both ends of the testing mechanism. One end of the delivery pipe is connected to an auxiliary box and a water tank respectively through a delivery pump. One side of the auxiliary box and the surface of the water tank are fixedly connected to the testing platform. An air inlet is opened on one side of the auxiliary box, and a filter screen is snapped into the inner wall of the air inlet. Multiple electric heating wires are installed on the inner wall of the auxiliary box, and a drain valve passes through one side of the water tank.

[0008] Furthermore, in order to better assist in clamping and fixing the pipeline valve, the placement mechanism includes a placement frame fixed above the testing platform. Multiple placement slots are provided above the placement frame. Electric telescopic rods are provided on both sides of the inner wall of the placement slots, and a clamping plate is provided at one end of the electric telescopic rods.

[0009] Furthermore, in order to better clamp and fix the pipe valve interface, the auxiliary mechanism includes multiple auxiliary frames fixedly installed above the testing platform, and multiple electric telescopic rods are provided on one side of the auxiliary frames, with an auxiliary plate provided at one end of each electric telescopic rod.

[0010] Furthermore, in order to better perform gas and liquid detection on pipeline valves, the detection mechanism includes multiple transparent detection cylinders fixedly connected to one side of the auxiliary plate. A detection connector is fixed to one end of each transparent detection cylinder. A pressure sensor passes through the top of two of the transparent detection cylinders. Multiple detection tubes pass through one side of the auxiliary plate. One end of each detection tube extends into the interior of the transparent detection cylinder. Control valves are installed at both ends of the detection tubes. One end of each control valve is connected to one end of the delivery pipe.

[0011] Furthermore, in order to better improve the sealing performance at the pipe valve interface, multiple sealing gaskets are fixed on one side of the test connector, one of which contacts one end of the transparent test tube, and multiple sealing rings are installed on one end of the test connector near the sealing gasket.

[0012] Furthermore, in order to drain the moisture inside the transparent detection tube, a drain hole is provided at the bottom of the transparent detection tube. A sealing plug is threaded onto the inner wall of the drain hole, and one end of the sealing plug is positioned opposite one end of the air pressure sensor.

[0013] Furthermore, in order to better provide auxiliary protection for the surface of the pipeline valve, multiple spring-loaded telescopic rods are fixedly installed on one side of the clamping plate, and a protective plate is fixed to one end of each spring-loaded telescopic rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) The detection mechanism set in the auxiliary mechanism can not only detect the pipeline valve, but also make auxiliary adjustments according to the size of the interface of the pipeline valve of different sizes, which is conducive to improving the sealing during detection and improving the detection effect. At the same time, the auxiliary mechanism set in the detection mechanism can not only detect the pipeline valve in both gas and liquid modes, but also perform auxiliary heating and drying treatment on the residual water adhering to the inner wall of the pipeline valve during gas detection, reducing the damage to the inner wall of the pipeline valve caused by the residual liquid.

[0016] (2) The placement mechanism set on the testing platform can be flexibly adjusted according to the different sizes of pipe valves, making it suitable for testing pipe valves of various specifications and meeting the needs of different production scenarios.

[0030] Example 2:

[0031] like Figures 1-6 As shown, a valve testing device for pipeline valve processing according to an embodiment of the present utility model includes a testing mechanism 4 connected to one side of an auxiliary mechanism 3. The testing mechanism 4 includes multiple transparent testing cylinders 401 fixedly connected to one side of an auxiliary plate 303. The transparent testing cylinders 401 are made of polycarbonate or other transparent pressure-resistant materials, which will not be described in detail. There are two transparent testing cylinders 401. A testing connector 402 is fixed to one end of the transparent testing cylinder 401. The testing connector 402 has a stepped cross-section to accommodate pipeline valves of different sizes. Multiple sealing gaskets 6 are fixed to one side of the testing connector 402. There are three sealing gaskets 6 to improve the tightness between the pipeline valve and the testing connector 402. One of the sealing gaskets 6 contacts one end of the transparent testing cylinder 401. Multiple sealing rings 7 are installed near the sealing gasket 6 at one end of the testing connector 402. There are six sealing rings 7, which are arranged in groups of two.

[0032] Two transparent detection cylinders 401 are equipped with pressure sensors 403 passing through their tops. The pressure sensors 403 are electrically connected to an alarm (not shown in the figure) during actual use. This alarm is used to alert personnel when a leak occurs in the pipeline valve. Two detection tubes 404 are passed through one side of the auxiliary plate 303. Each detection tube 404 is a flexible telescopic tube. One end of each detection tube 404 extends into the transparent detection cylinder 401. Control valves 405 are installed at both ends of each detection tube 404. A discharge hole is provided at the bottom of the transparent detection cylinder 401 to discharge any liquid adhering to or leaking from the inner wall of the transparent detection cylinder 401 during detection. A sealing plug 8 is threaded onto the inner wall of the discharge hole. One end of the sealing plug 8 is opposite to one end of the pressure sensor 403.

[0033] One end of the detection mechanism 4 is connected to an auxiliary mechanism 5. The auxiliary mechanism 5 includes a delivery pipe 501 connected to both ends of the detection mechanism 4. One end of the control valve 405 is connected to one end of the delivery pipe 501. One end of the delivery pipe 501 is connected to an auxiliary box 502 and a water tank 503 via a delivery pump. The water tank 503 has a U-shaped cross-section. One side of the auxiliary box 502 and the surface of the water tank 503 are fixedly connected to the detection platform 1. An air inlet is provided on one side of the auxiliary box 502. A filter screen 504 is snapped onto the inner wall of the air inlet. The filter screen 504 is a replaceable and cleanable structure.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In summary, with the help of the above-mentioned technical solution of this utility model, the pipeline valve to be tested is placed in the placement groove of the placement frame 201. Then, the electric telescopic rod 302 set in the auxiliary frame 301 pushes the auxiliary plate 303 to adjust the position of the test connector 402 and the valve interface, ensuring that the sealing gasket 6 and the sealing ring 7 fit tightly to adapt to valves of different sizes. After fixing, the electric telescopic rod 202 on both sides of the placement groove drives the clamping plate 203 to move. The valve is flexibly clamped by the spring-loaded telescopic rod 9 and the protective plate 10. This not only helps to fix the pipeline valve, but also helps to protect the surface of the pipeline valve.

[0037] Liquid detection: Control valve 405 switches to the water tank 503 passage, and the delivery pump injects liquid into the transparent detection tube 401 through the detection tube 404 to observe whether there is leakage. If there is leakage, the liquid will be discharged from the discharge hole through the sealing plug 8 and flow into the water tank 503.

[0038] Gas detection: Control valve 405 switches to the auxiliary box 502 passage, and gas enters the transparent detection cylinder 401 through the delivery pipe 501. The pressure sensor 403 monitors the pressure change in real time. If the pressure is abnormal, the alarm is triggered.

[0039] During gas detection, the electric heating wire 505 inside the auxiliary box 502 heats the input gas. The hot air is then introduced into the inner wall of the valve through the detection tube 404 to dry any residual liquid and prevent corrosion damage. The filter screen 504 in the auxiliary box 502 can filter impurities in the gas used for detection, ensuring a clean drying process. The drain valve 506 in the water tank 503 periodically discharges the detection wastewater. The filter screen 504 in the auxiliary box 502 can be removed for cleaning, ensuring long-term stable operation of the device.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
