Description

Technical Field

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automated control systems, with a wide variety of types and specifications. An existing patent, CN218646521U, describes a valve testing device for pipeline valve processing, including a workbench. A lower fixed plate is positioned above the workbench. Limit seats are symmetrically fixedly connected to the top of the lower fixed plate. Slide plates are slidably connected to the inner walls of both limit seats. Positioning clamps are fixedly connected to the ends of the two slide plates that are close to each other. A bidirectional screw is threaded between the inner walls of the ends of the two slide plates that are far apart. A knob is fixedly connected to one end of the bidirectional screw. First, turn the knob to rotate the double-ended screw, which will move the two slide plates to adjust the distance between the two positioning clamps so that the positioning clamps are adapted to the size of the valve. Then, place the valve vertically between the two positioning clamps. The positioning clamps can quickly calibrate the valve and facilitate positioning. Then, the telescopic cylinder will move the upper fixed plate down, so that the upper fixed plate and the lower fixed plate are clamped to fix the valve, thereby achieving the effect of facilitating valve fixation.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can be tested using water, water testing inevitably causes water accumulation inside the valve. If the accumulated water persists for a long time, it will cause rust, reducing the valve's service life and leading to economic losses due to valve damage. Therefore, we propose a valve testing device for pipeline valve processing to solve the above-mentioned problems. Utility Model Content

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.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a valve testing device for pipeline valve processing, including a test bench 1. The top surface of the test bench 1 is inclined, and a through hole is opened inside the test bench 1. The through hole is a positioning hole 101, and there are four positioning holes 101. The four positioning holes 101 are respectively opened at the four corners inside the test bench 1. The test bench 1 and the positioning holes 101 together form a connection structure. A guide rail 102 is fixedly connected to the inner side of the test bench 1. The main body of the guide rail 102 is arranged horizontally, and the guide rail 102 and the test bench 1 together form a support structure. A horizontal groove is opened inside the guide rail 102.

[0025] By providing positioning holes 101 at each of the four corners of the test bench 1, it is possible to quickly install the test bench 1 during use.

[0026] See Figure 2 , Figure 3 A motor 103 is installed on the left end face of the test bench 1, and an output shaft is provided on the right side of the motor 103. The output shaft passes through the test bench 1 to the right and is located in the transverse groove opened in the guide rail 102. A screw 104 is installed on the output shaft provided on the right side of the motor 103, and the screw 104 is rotatably connected to the inner side of the guide rail 102 through a bearing seat.

[0027] By installing a screw 104 on the right output shaft of the motor 103, a stable power output to the moving platform 2 can be achieved during use.

[0028] See Figure 1 , Figure 4 The motor 103 and the screw 104 together form the drive structure, and the transverse groove opened in the guide rail 102 is equipped with a moving platform 2. The main body of the moving platform 2 is arranged longitudinally, and there are two moving platforms 2. The outer sides of the two moving platforms 2 are fixedly connected with a locking block 201.

[0029] By fixing two locking blocks 201 opposite each other on the outside of the mobile station 2, the locking blocks 201 can prevent the mobile station 2 from falling out when it is moving.

[0030] See Figure 5 , Figure 6The locking block 201 is a structure that protrudes from the moving platform 2, and two locking blocks 201 are fixedly connected to each other on the outer side of the moving platform 2. The moving platform 2 is slidably connected to the transverse groove opened in the guide rail 102 through the locking blocks 201 fixedly connected to its outer surface, and the interior of the moving platform 2 is provided with a screw hole that matches the screw 104.

[0031] By providing a screw hole inside the mobile stage 2 that matches the screw 104, stable transmission operations can be achieved.

[0032] See Figure 1 , Figure 2 The moving platform 2 has a longitudinal groove inside, and an electric push rod 202 is fixedly connected inside the longitudinal groove. The main body of the electric push rod 202 is arranged longitudinally, and a base plate 203 is installed on the top surface of the electric push rod 202. Two sliders 204 are fixedly connected to the outer side of the base plate 203 in opposite directions.

[0033] An electric push rod 202 is fixedly connected inside the moving platform 2, which can push the base plate 203 during use.

[0034] See Figure 4 , Figure 6 The base plate 203 is slidably connected to the longitudinal groove opened in the moving table 2 by the slider 204 fixedly connected to its outer side surface, and a guide rod 205 is fixedly connected to the top surface of the base plate 203, and the main body of the guide rod 205 is a cylindrical structure.

[0035] By fixing a guide rod 205 to the top surface of the base plate 203, it can support the baffle 3 and the barrier plate 303 during use.

[0036] See Figure 1 , Figure 3 A baffle 3 and a baffle 303 are fixedly connected to the top surface of the two guide rods 205 respectively. A plug 301 is fixedly connected to the inner side of the baffle 3 and the baffle 303, and an air hole 304 is opened. A pump 302 is fixedly connected to the left end face of the baffle 3, and a pressure gauge 305 is installed on the right side face of the baffle 303 located on the right side.

[0037] A pressure gauge 305 is fixedly connected to the right end face of the baffle plate 303, so that the gas pressure can be monitored during use.

[0038] During operation, when the pipeline valve is being tested, the test bench 1 can be placed on the workbench or corresponding support, and the test bench 1 can be quickly fixed by passing the bolt through the positioning hole 101 in the test bench 1. The valve to be tested can be placed on the test bench 1 and the guide rail 102. The motor 103 installed on the left end face of the test bench 1 can be started to drive the screw 104 to rotate.

[0039] Furthermore, when the screw 104 rotates, it can synchronously drive the two moving platforms 2 through the transmission connection between them. The two moving platforms 2 can move synchronously along the transverse groove opened in the guide rail 102 using the card block 201 fixedly connected to their outer surface to adjust the distance between the baffle 3 and the barrier plate 303. This allows the plug 301 fixedly connected to the barrier plate 303 and the inner side of the baffle 3 to be inserted into the valve. The pump 302 installed on the outer side of the baffle 3 is started to pressurize the valve and perform the corresponding pressure holding operation. Then, the pressure gauge 305 set on the right end face of the barrier plate 303 is used to monitor whether the gas pressure in the valve meets the standard. If the gas pressure fails to meet the standard, it can be simultaneously indicated that there is a gas leak in the valve.

[0040] In summary, by using gas for monitoring, this device can avoid the excessive corrosion of valves that would result from using water for monitoring.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
