Description

Technical Field

[0001] This utility model belongs to the field of regulating valve processing technology, and in particular relates to a regulating valve processing pressure mechanism. Background Technology

[0002] Control valves are used in industrial automation process control to regulate process parameters such as flow rate, pressure, temperature, and liquid level. Based on control signals from the automation system, they automatically adjust the valve opening to regulate these parameters. Each batch of control valves produced in the factory undergoes a pressure test before leaving the factory.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: the existing pressure testing mechanism for regulating valves (such as the patent application number CN202322605478.4 - a pressure testing auxiliary tool for sealing a pneumatic regulating valve) can usually only test the pressure resistance performance of the valve body at a specific angle. However, in actual applications, the valve body may not be horizontal or vertical, but may be installed at an angle. Therefore, the existing pressure resistance performance test of regulating valves is insufficient to meet the actual needs, and the test results are not reliable and accurate enough.

[0004] To address this issue, we propose a pressure-pressurizing mechanism for regulating valves. Utility Model Content

[0005] The main purpose of this utility model is to provide a pressure testing mechanism for regulating valves, which has a wider pressure resistance testing range for regulating valves, and therefore the testing structure is more reliable and accurate, effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A regulating valve processing pressure testing mechanism includes a bottom support and a regulating valve pressure testing module located on the bottom support. A top support plate is welded to one side of the top wall of the bottom support. The regulating valve pressure testing module includes a motor installed on one side wall of the top support plate, two inner connecting shafts connected inside the top support plate, and an installation tube fixedly welded between the two inner connecting shafts. The output shaft of the motor is coaxially connected to one of the inner connecting shafts. The two inner connecting shafts are rotatably installed on the inner walls on both sides of the top support plate, so that the motor can drive the installation tube and the two inner connecting shafts to rotate when it runs. The motor requires external power supply.

[0008] Flanges are integrally connected to both sides of the installation pipe, and the installation pipe is connected to a water pipe and the valve body to be tested through the two flanges respectively. A flexible hose is fixedly connected to the side of the water pipe facing away from the installation pipe. The flexible hose has a certain degree of flexibility and will not be damaged after a certain deformation, and can maintain normal water flow function. A fixing pipe is fixedly connected to the side of the flexible hose facing away from the installation pipe. The fixing pipe is used to connect to the external water supply pipe and to flow water into the valve body to test the pressure resistance performance of the valve body.

[0009] As a preferred embodiment, flanges are also connected to the water pipe and the valve body to be tested, and the flanges on the water pipe and the valve body to be tested are respectively adapted to the two flanges on the installation pipe, and the two adapted flanges are fixed together by multiple sets of bolts and nuts; the multiple sets of bolts and nuts are distributed in a circumferential array on the outside of the flanges, so that the two flanges fit tightly.

[0010] As a preferred embodiment, a valve is installed on the fixed pipe; the valve can be a manual valve or an electric valve, used to open or close the fixed pipe.

[0011] As a preferred embodiment, a sleeve is welded to the outer wall of the fixed pipe, wherein the bottom of the sleeve extends downward and is welded to the bottom support; thereby ensuring the stability of the fixed pipe, wherein the fixed pipe always remains horizontal and stationary, while the hose can rotate within a certain range as the water pipe rotates, but this will not affect the operation of the water pipe, the hose and the fixed pipe.

[0012] As a preferred embodiment, a limiting frame is fitted on the outside of the hose, wherein the limiting frame has a through hole for the hose to pass through, and the limiting frame is welded to the bottom support; the limiting frame can appropriately limit the position of the hose and prevent the hose from being placed haphazardly.

[0013] As a preferred embodiment, a cover is also welded onto the top support plate, wherein the cover is located outside the motor; thereby the cover protects the motor, and a heat dissipation groove is formed at the bottom of the cover, and the heat dissipation groove is used to dissipate heat from the motor.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] The pressure testing mechanism for this regulating valve allows for the release of sufficient water into the valve body to be tested after connecting it to the water pipe, and then allows it to stand still. During the standing process, the drive motor rotates to rotate the regulating valve and the water pipe, thereby testing the pressure resistance of the regulating valve at different angles. Compared with existing technologies, this pressure testing mechanism for regulating valves has a wider pressure resistance testing range, and therefore the testing structure is more reliable and accurate.

[0016] The pressure testing mechanism for this regulating valve requires a drive motor to rotate the mounting pipe and two internal connecting shafts within a certain angle range, as the actual installation angle of the valve body under test may not be horizontal or vertical. This rotation causes the valve body under test to rotate, thereby testing its pressure resistance at different angles. Through this test, the test results for the valve body under test become more reliable and accurate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A regulating valve processing and pressurizing mechanism includes a bottom support 1 and a regulating valve pressurizing module located on the bottom support 1. A top support plate 2 is welded to one side of the top wall of the bottom support 1. The regulating valve pressurizing module includes a motor 3 installed on one side wall of the top support plate 2, two inner connecting shafts 6 connected inside the top support plate 2, and an installation pipe 7 fixedly welded between the two inner connecting shafts 6. The output shaft of the motor 3 is coaxially connected to one of the inner connecting shafts 6. In addition, a cover 4 is welded to the top support plate 2. The cover 4 is located outside the motor 3, thereby protecting the motor 3. A heat dissipation groove 5 is formed at the bottom of the cover 4, and the heat dissipation groove 5 is used to dissipate heat from the motor 3. The two inner connecting shafts 6 are rotatably installed on the inner walls on both sides of the top support plate 2, so that the motor 3 can drive the installation pipe 7 and the two inner connecting shafts 6 to rotate when running. The motor 3 requires external power supply.

[0023] Flanges 13 are integrally connected to both sides of the mounting pipe 7, and the mounting pipe 7 is connected to the water pipe 8 and the valve body 12 to be tested through the two flanges 13 respectively. Flanges 13 are also connected to the water pipe 8 and the valve body 12 to be tested. The flanges 13 on the water pipe 8 and the valve body 12 to be tested are adapted to the two flanges 13 on the mounting pipe 7 respectively. The two adapted flanges 13 are fixed together by multiple sets of bolts and nuts. The multiple sets of bolts and nuts are distributed in a circumferential array on the outside of the flanges 13, so that the two flanges 13 fit tightly.

[0024] Meanwhile, a flexible hose 9 is fixedly connected to the side of the water pipe 8 facing away from the installation pipe 7. The flexible hose 9 has a certain degree of extensibility and will not be damaged after a certain deformation, and can maintain normal water flow function. A fixed pipe 10 is fixedly connected to the side of the flexible hose 9 facing away from the installation pipe 7. The fixed pipe 10 is used to connect to the external water supply pipe and to flow water into the valve body 12 to test the pressure resistance performance of the valve body 12.

[0025] For the hose 9, it should be noted that a limiting frame 14 is provided on the outside of the hose 9, wherein the limiting frame 14 has a through hole 15 for the hose 9 to pass through, and the limiting frame 14 is welded to the bottom support 1. The limiting frame 14 can appropriately limit the position of the hose 9 to prevent the hose 9 from being placed in a mess.

[0026] For the fixed pipe 10, it should be noted that a valve 11 is installed on the fixed pipe 10. The valve 11 can be a manual valve or an electric valve, which is used to open or close the fixed pipe 10. A pipe sleeve 16 is welded to the outer wall of the fixed pipe 10. The bottom of the pipe sleeve 16 extends downward and is welded to the bottom support 1, thereby ensuring the stability of the fixed pipe 10. The fixed pipe 10 always remains horizontal and stationary, while the hose 9 can rotate within a certain range as the water pipe 8 rotates, but this will not affect the operation of the water pipe 8, the hose 9, and the fixed pipe 10.

[0027] The pressure testing mechanism of this regulating valve is as follows: In use, firstly, the valve body 12 to be tested is fitted with the flange 13 on the mounting pipe 7 through the flange 13 on it, and fixed with multiple sets of bolts and nuts. Then, the valve body 12 to be tested is set to the closed state. Then, it is connected to the external water supply pipe through the fixed pipe 10, and water is added to the fixed pipe 10. The water enters the mounting pipe 7 through the hose 9 and the water pipe 8, and then enters the valve body 12 to be tested and stays there. Then, it is left to stand for a period of time (the time is determined according to the actual needs) to test the pressure resistance performance of the valve body 12 to be tested.

[0028] During this process, (since the actual installation angle of the valve body 12 under test may not be horizontal or vertical), the motor 3 can also be driven to rotate the mounting tube 7 and the two inner connecting shafts 6 within a certain angle range, thereby rotating the valve body 12 under test (this range is: as shown in the attached figure). Figure 1-3 The position shown is used as a reference, and the valve body 12 is rotated 45° clockwise and counterclockwise in each direction to test its pressure resistance performance at different angles. The specific number of degrees the valve body 12 is rotated each time and the time it stays at each angle are determined according to actual needs and are not limited here. Through the above test, the test results of the valve body 12 are made more reliable and accurate.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
