Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to a ball valve testing fixture. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves can not only flexibly control the merging, splitting, and switching of media in pipelines, but also close any channel while connecting the other two channels.

[0003] When testing the air tightness of a ball valve, the ball valve's inlet and outlet are fixedly connected to the ball valve mounting flanges on the main testing unit and the auxiliary testing unit, respectively. The main testing unit injects high-pressure water into the ball valve, and the air tightness of the ball valve can be detected by observing whether water leakage occurs.

[0004] However, there are many types of ball valves available, especially irregularly shaped ball valves. Often, the inlet and outlet heights of irregularly shaped ball valves are inconsistent. Therefore, when the ball valve is installed between the main testing unit and the auxiliary testing unit, the ball valve cannot be properly tested because the inlet and outlet heights of the ball valve are inconsistent. Utility Model Content

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves can not only flexibly control the merging, splitting, and switching of media in pipelines, but also close any channel while connecting the other two channels.

[0030] In related technologies, when ball valve testing equipment performs airtightness testing on ball valves, the inlet and outlet of the ball valve need to be fixedly connected to the ball valve mounting flanges on the main testing unit and the auxiliary testing unit, respectively. The main testing unit injects high-pressure water into the ball valve, and the airtightness of the ball valve can be detected by observing whether the ball valve leaks.

[0031] To address some of the problems in related technologies, this application provides a ball valve testing fixture. When needed, the irregular-shaped ball valve is simply placed inside the flange interface 171 on the opposite side of the ball valve testing auxiliary machine 17 and the ball valve testing main machine 12. The motor 14 is then started to drive the support plate 15 to rise and fall, thereby fixing the irregular-shaped ball valve. Then, the testing mechanism is used to test it. This device allows for easy adjustment of the height of the flange interface 171 on one side of the ball valve testing auxiliary machine 17 according to the shape of the ball valve, to meet the needs of irregular flanges, making it more convenient to use and increasing work efficiency.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-4 This application provides a ball valve testing fixture, including a testing component 1. The testing component 1 includes: a base 11 with a ball valve testing host 12 mounted on its top; a frame 13 mounted on the top of the base 11; a motor 14 mounted inside the frame 13; a lead screw 141 mounted on the output shaft of the motor 14; a support plate 15 inserted into the inside of the frame 13 and threadedly connected to the lead screw 141; a mounting plate 16 mounted on the top of the support plate 15; a ball valve testing auxiliary machine 17 mounted on the bottom of the mounting plate 16; flange interfaces 171 symmetrically arranged on the ball valve testing auxiliary machine 17 and the ball valve testing host 12; and a fixing plate 18 mounted on the top of the base 11 and passing through the mounting plate 16.

[0034] First, place the irregular ball valve to be tested inside the flange interface 171 on the opposite side of the ball valve testing auxiliary machine 17 and the ball valve testing main machine 12. Then, start the motor 14 with an external power supply to drive the lead screw 141 to rotate. Since the lead screw 141 is threadedly connected to the support plate 15, the support plate 15 can be raised or lowered by controlling the motor 14 to rotate forward or backward. This allows the height of the flange interface 171 on one side of the ball valve testing auxiliary machine 17 to be adjusted according to the shape of the ball valve to meet the requirements of the irregular flange. After adjustment, use a tool to fix the ball valve inside the two sets of flange interfaces 171. Then, the ball valve testing auxiliary machine 17 can be started to test the ball valve. The working principle of the ball valve testing auxiliary machine 17 is described in paragraph "

[0019] " of the specification of the patent "CN220542343U", which is common knowledge and will not be repeated here.

[0035] In some embodiments, an auxiliary component 2 is provided on the mounting plate 16. The auxiliary component 2 includes: a protective frame 21 disposed on the top of the mounting plate 16; a second motor 22 disposed on the inner side of the protective frame 21; a second lead screw 221 rotatably disposed on the inner side of the protective frame 21 and connected to the second motor 22; an adjusting block 23 disposed on the inner side of the protective frame 21 and threadedly connected to the second lead screw 221; a slide rail 231 opened at the bottom of the mounting plate 16; and a connecting block 24 disposed at the bottom of the adjusting block 23 and passing through the slide rail 231 to connect to the ball valve detection auxiliary machine 17.

[0036] The motor 22 is started by an external power source, which drives the lead screw 221 to rotate. The rotation of the lead screw 221 will drive the adjusting block 23 connected to it to move, thereby causing the connecting block 24 to slide inside the slide rail 231, so as to adjust the position of the ball valve detection auxiliary machine 17. This can accommodate ball valves of different lengths and also facilitate the compression and limiting of the ball valve, so as to avoid the operator from fixing the installation and increase the practical effect.

[0037] In some embodiments, the auxiliary component 2 further includes a collection slot 25 formed on the top of the base 11.

[0038] A collection trough 25 is provided on the top of the base 11 to collect the water that drips during the testing process, making it easier for operators to clean up the water later, making the use more convenient and reducing the workload of operators.

[0039] In some embodiments, the auxiliary component 2 further includes: a slide groove 26 symmetrically formed on the frame 13; and a slide rod 261 symmetrically arranged on the support plate 15.

[0040] Slide grooves 26 are symmetrically opened on both sides of the frame 13, and slide rods 261 are symmetrically arranged on both sides of the support plate 15. When the support plate 15 moves up and down, the slide rods 261 will slide inside the slide grooves 26, which can limit the support plate 15 and prevent the support plate 15 from separating from the frame 13 due to operational errors, thus increasing safety.

[0041] In some embodiments, the slide bar 261 is a screw.

[0042] The slide rod 261 is set as a screw and threadedly connected to the support plate 15. This allows the slide rod 261 to be removed from the support plate 15 by rotating it. Then the limit on the support plate 15 can be released so that it can be removed to maintain or replace the internal parts of the frame 13, thus increasing the service life of the device.

[0043] In some embodiments, the inner side of the collection trough 25 is inclined.

[0044] The inner side of the collection tank 25 is designed to slope outwards. This prevents water from accumulating on the inner side of the collection tank 25, allowing operators to collect dripping water. Excessive water accumulation on the inner side of the collection tank 25 can cause parts to rust, thus increasing the service life of the device.

[0045] In some embodiments, the support plate 15 and the mounting plate 16 are connected by bolts.

[0046] The support plate 15 and the mounting plate 16 are bolted together, which makes it easy to remove the mounting plate 16 later for repair or replacement of parts, so as not to affect subsequent use.

[0047] In some embodiments, the auxiliary component 2 further includes a sponge pad 27 disposed on the inner side of the frame 13.

[0048] A sponge pad 27 is provided on the inside of the frame 13 to clean the surface of the support plate 15, preventing debris or dust from adhering to the surface of the support plate 15, thus affecting the cleanliness of the support plate 15 surface and increasing the aesthetics of the device.
