Description

Technical Field

[0001] The invention relates to a valve detection device, in particular to a valve air tightness detection device. Background Art

[0002] In the process of valve production and processing, in order to ensure the production quality of the valve, the valves must be tested for air tightness before they are sold. Only when the valves have no leakage and meet the national sealing level can they be qualified products and can they be sold later.

[0003] When testing a valve, the existing testing equipment first places the valve to be tested at the testing station, drives the sealing member to seal the two ends of the valve by the driving member, and then passes high-pressure gas into the valve to test the air tightness of the valve to see if there is any leakage in the valve.

[0004] Since the appearances of valves of different models vary greatly and there is no standard, it is difficult for existing inspection stations to match valves with different appearances, making it difficult for valves to be placed horizontally when placed at the inspection station. When the placed valve is tilted greatly, a large gap is easily generated between the seal and the end face of the valve, causing leakage. This greatly affects the inspection efficiency of the valve and also leads to poor versatility of existing inspection equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a valve air tightness detection device, which can detect valves of different models, is easy to operate, has high detection efficiency and better versatility.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a valve air tightness detection device, including a fuselage and a water reservoir formed on the fuselage, a lifting platform is provided above the water reservoir, driving parts are symmetrically arranged on the lifting platform, each of the driving parts is connected to a sealing part, one of the sealing parts is connected to an air intake pipe, and a detection platform is provided on the lifting platform at a position between the two sealing parts via a rotating shaft, and a detection station for placing the valve and corresponding to the sealing part is formed on the detection platform, and the axis of the rotating shaft is parallel to the symmetry line of the two sealing parts.

[0007] By adopting the above technical solution, the valve to be tested is placed at the testing station, and the two ends of the valve are respectively facing the two seals to correspond thereto. The placement state of the valve is adjusted by rotating the testing platform, and the valve is adjusted to a horizontal placement state. At this time, the end face of the valve and the sealing surface of the seal are parallel to each other. Then, the seal is driven by the driving member to seal against the end face of the valve, so that a close fit between the seal and the end face of the valve can be achieved, thereby avoiding leakage. This type of testing equipment is not limited by the outer contour of the valve, so it can be used for accurate testing of valves of different models. It is easy to operate, has high testing efficiency, and has better versatility.

[0008] It is further configured as follows: it includes a plurality of templates inserted and fixed on the detection platform, and the detection stations are formed on the plurality of templates.

[0009] By adopting the above technical solution, when the outer contours of the valves differ greatly, the template can be replaced by plugging and unplugging, and the detection station can be roughly adjusted, so that the equipment can be better suitable for the detection of valves of different models. This method also reduces the probability of leakage and makes the detection more accurate and efficient.

[0010] It is further configured as follows: the detection platform includes a base plate and a plurality of connecting columns movably arranged on the base plate, a locking piece for locking the connecting column is provided between each of the connecting columns and the base plate, and a slot for inserting a template is formed on each of the connecting columns.

[0011] By adopting the above technical solution, the position of the template is adjusted by the movably arranged connecting column and locked by the locking member, so that the position of the template can form a more stable and effective support for the placed valve, thereby improving the stability of the valve placement and further increasing the versatility of the equipment.

[0012] It is further configured as follows: each of the driving members is arranged on the lifting platform and reciprocates and slides toward the detection station, and a limiting component is provided between each of the driving members and the detection platform for the driving member to slide and limit the driving member from leaving the detection platform.

[0013] By adopting the above technical solution, the sliding lifting platform increases the placement space of the detection platform, making the placement operation of the valve more convenient; the force is borne by the setting of the limit component, reducing the bearing force on the driving part, thereby extending the service life of the driving part.

[0014] It is further configured as follows: the limit assembly includes a first limit hook arranged on the driving member and a second limit hook arranged on the detection platform and connected to the first limit hook.

[0015] By adopting the above technical solution, the first limit hook cooperates with the second limit hook to limit the driving member from moving back to the detection station and separating from the detection platform.

[0016] It is further configured that: a buffer spring is connected between each of the driving members and the lifting platform.

[0017] By adopting the above technical solution, the setting of the buffer spring plays a buffering role on the instantaneous force of the driving member, thereby extending the service life of the driving member and the equipment.

[0018] It is further configured as follows: a driving component for driving the detection platform to rotate is provided on the lifting platform, and the driving component includes a first motor arranged on the lifting platform, a driving pulley arranged on the output shaft of the first motor, a driven pulley arranged on the rotating shaft and rotating therewith, and a transmission belt connecting the driving pulley and the driven pulley.

[0019] By adopting the above technical solution, the first motor drives the detection platform to rotate through the transmission belt, and the adjustment is achieved mechanically instead of manually, which is more automated and more efficient.

[0020] It is further configured as follows: a control component for controlling the opening and closing of the valve to be detected is provided above the detection platform, the lifting platform is slidably arranged on the fuselage, and a second driving component for driving the lifting platform to rise and fall is provided on the fuselage.

[0021] By adopting the above technical solution, adjustment is achieved mechanically instead of manually, which is more automated and more efficient.

[0022] It is further configured that: the control component includes a control rod, a third driving member driving the control rod to rotate, and a lifting assembly driving the control rod to rise and fall.

[0023] By adopting the above technical solution, the lifting assembly cooperates with the third driving member to drive the control rod to move the handle of the valve, thereby realizing mechanical control of opening and closing.

[0024] It is further configured as follows: the lifting assembly includes a sliding seat slidably arranged on the fuselage and a fourth driving member driving the sliding seat to slide, the third driving member is arranged on the sliding seat, and the third driving member is connected to the control rod.

[0025] By adopting the above technical solution, the lifting assembly controls the sliding movement of the slide seat to change the position height of the control rod.

[0026] In summary, the present invention has the following beneficial effects: the detection equipment can detect valves of different models and with large differences in appearance profiles, and is easy to operate, has high detection efficiency and better versatility; the equipment can also realize real-time storage of detection data, which is convenient for later viewing.
