Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic valve testing technology, and in particular to a testing device for pneumatic valves. Background Technology
[0002] Pneumatic valves are valves driven by compressed air. In order to compete with their products, pneumatic valve manufacturers have made different innovations under the unified design concept of pneumatic valves, forming their own corporate standards and product characteristics.
[0003] Currently, after pneumatic valves are manufactured, they need to be tested to determine their quality. However, current testing equipment uses liquid as the testing medium, which cannot maximize the valve's responsiveness. Furthermore, during testing, only one port of the valve is blocked, leading to leakage of the testing medium and resulting in unsatisfactory and inaccurate test results. Additionally, the valve needs to be clamped and secured during testing, and existing clamping structures require manual operation by testing personnel, which is cumbersome and labor-intensive. Therefore, there is room for improvement. Utility Model Content
[0004] This invention provides a testing device for pneumatic valves to solve the problems mentioned in the background art.
[0005] To address the aforementioned problems, this utility model provides a testing device for pneumatic valves, comprising a workbench, a testing instrument, an air pump, and a clamping mechanism. A first electric telescopic rod and a second electric telescopic rod are symmetrically mounted at both ends of the workbench via support frames. The testing instrument is located on the right rear side of the workbench, and the air pump is located on the left rear side of the workbench. The clamping mechanism is located in the middle of the workbench, between the first and second electric telescopic rods. A vent seat is detachably mounted at the end of each of the first and second electric telescopic rods. The vent seat in the first electric telescopic rod is connected to the testing instrument via a pipe, and the vent seat in the second electric telescopic rod is connected to the air pump via a pipe.
[0006] Preferably, the clamping mechanism consists of a mounting plate, a clamping plate, and a spring. The mounting plate is symmetrically installed in the workbench, and three guide rods are slidably connected to the mounting plate. The end of each guide rod away from the mounting plate is connected to the clamping plate, and the spring is sleeved in the guide rod between the mounting plate and the clamping plate. A sliding groove is provided at the lower part of both ends of the clamping plate in the workbench. The bottom of both ends of the clamping plate is slidably connected to the sliding groove. An arc-shaped groove is provided at the top of the clamping plate, and the arc-shaped groove is coaxial with the vent seat.
[0007] Preferably, a rubber sealing sleeve is connected to the front end of the vent seat via a thread.
[0008] The beneficial effects of adopting the above technical solutions are:
[0009] 1. The tubes at both ends of the valve body are placed through the arc groove in the clamping plate. Then, the valve body is clamped from both sides by the two clamping plates through the action of the spring, guide rod and slide groove. Then, the vent seats are sealed and inserted into the outlet and inlet ends of the valve body by the first electric telescopic rod and the second electric telescopic rod respectively. Then, the air pump works to send gas into the valve body through the vent seat on the second electric telescopic rod. If the valve body is not qualified, the leaked gas will enter the vent seat in the first electric telescopic rod and then be poured into the detector. The detector will give feedback of unsuitability. Monitoring is time-saving and labor-saving, and the detection is accurate.
[0010] 2. By setting the rubber sealing sleeve, the inlet and outlet ends of the valve body can be sealed to ensure the detection effect, while avoiding rigid collision between the vent seat and the valve body, which could cause damage. Attached Figure Description

Detailed Implementation
[0015] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] like Figure 1-3 In this embodiment, a testing device for a pneumatic valve includes a workbench 1, a detector 2, an air pump 3, and a clamping mechanism 4. A first electric telescopic rod 5 and a second electric telescopic rod 6, symmetrically mounted on opposite ends of the workbench 1 via support frames 11, are mounted on the right rear side of the workbench 1. The detector 2 is located on the right rear side of the workbench 1, and the air pump 3 is located on the left rear side of the workbench 1. The clamping mechanism 4 is located in the middle of the workbench 1, between the first electric telescopic rod 5 and the second electric telescopic rod 6. A vent seat 7 is detachably mounted at the ends of both the first and second electric telescopic rods 5 and 6. The vent seat 7 in the first electric telescopic rod 5 is connected to the detector 2 via a pipe, and the vent seat 7 in the second electric telescopic rod 6 is connected to the air pump 3 via a pipe.
[0019] With the above technical solution, the valve body is placed in the clamping mechanism 4 during use. Then, the first electric telescopic rod 5 and the second electric telescopic rod 6 are activated, driving the vent seat 7 to be inserted into both ends of the valve body. Then, the air pump 3 works to send gas into the vent seat 7 in the second electric telescopic rod 6. The gas then enters the valve body. If the valve body has poor sealing, gas leakage will enter the other side of the valve body, thus entering the vent seat 7 in the first electric telescopic rod 5. The gas is then guided to the detector 2 through the vent seat 7. The detector 2 provides feedback, making detection convenient, accurate, and improving detection efficiency.
[0020] Preferably, the clamping mechanism 4 consists of a mounting plate 41, a clamping plate 42, and a spring 43. The mounting plate 41 is symmetrically installed in the workbench 1, and three guide rods 44 are slidably connected in the mounting plate 4. The end of the guide rod 44 away from the mounting plate 41 is connected to the clamping plate 42, and the spring 43 is sleeved in the guide rod 44 between the mounting plate 41 and the clamping plate 42. A sliding groove 12 is opened in the lower part of both ends of the clamping plate 42 in the workbench 1. The bottom of both ends of the clamping plate 42 is slidably connected to the sliding groove 12. An arc-shaped groove 421 is opened at the top of the clamping plate 42, and the arc-shaped groove 421 is coaxial with the vent seat 7.
[0021] Through the above technical solution, the mounting plate 41, guide rod 44, and spring 43 make the clamping plate 42 elastic, which facilitates the positioning of the valve body from both sides. The arc groove 421 makes the inlet end and outlet end of the valve body coaxial with the vent seat 7. Then, the first electric telescopic rod 5 and the second electric telescopic rod 6 drive the vent seat 7 to be inserted into the valve body from both ends, and positioning is performed at the same time as testing. This eliminates the need for operators to frequently disassemble the clamping mechanism 4, thus improving work efficiency.
[0022] Preferably, the front end of the vent seat 7 is connected to a rubber sealing sleeve 71 by means of threads.
[0023] Through the above technical solution, the rubber sealing sleeve 71 is provided to ensure the sealing of the vent seat 7 when it is inserted into the valve body, while avoiding rigid collisions, and also to facilitate the replacement of the appropriate rubber sealing sleeve 71 according to the size of the valve body port, thereby improving applicability.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
