Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve testing auxiliary tools, and in particular to a valve plate testing auxiliary tooling. Background Technology
[0002] The valve plate is a very important component of a valve, and its quality has a significant impact on the valve's sealing performance. Therefore, the valve plate is currently inspected using ultrasonic testing or X-ray inspection before assembly to detect the presence of pinholes. Ultrasonic testing requires ultrasonic equipment, and the results are greatly affected by the ambient temperature and humidity. X-ray inspection, on the other hand, poses certain radiation risks. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes an auxiliary tooling for valve plate testing. During testing, the valve plate can be clamped and then vented through it. The valve plate can be placed in water to observe whether bubbles are generated, thus determining the quality of the valve plate. The operation is simple and convenient, unaffected by ambient temperature and humidity, and there is no radiation.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A valve plate testing auxiliary fixture includes a frame, a first sleeve, a second sleeve, a first guide head, a second guide head, a first gasket, and a second gasket. The second sleeve is fixedly mounted on the frame, the second guide head is mounted on the second sleeve, and the second gasket is fitted onto the second guide head. A lead screw assembly is mounted on the frame, the first sleeve is mounted on the lead screw assembly, the first guide head is mounted on the first sleeve, and the first gasket is fitted onto the first guide head. The first gasket and the second gasket are parallel to each other, and the first guide head and the second guide head are aligned in a straight line. The first guide head is cylindrical, and the second guide head is tubular.
[0006] The auxiliary tooling is used as follows: the first sleeve is moved by the lead screw assembly, so that the valve plate is located between the first sleeve and the second sleeve. The first sleeve is further moved by the lead screw assembly, and the first and second shims are respectively pressed against the cross-section of the valve plate from both ends. The first guide head and the second guide head enter the through hole of the valve plate. The first guide head is columnar and the second guide head is tubular. Then, the air pipe is connected to one end of the second guide head, and air is injected into the second guide head using the air pipe. The entire valve plate is then immersed in water. Observe whether there are bubbles in the water. If there are bubbles, it means that there are defects such as sand holes on the valve plate. If no bubbles are generated, it means that the valve plate is good.
[0007] In summary, this auxiliary tooling can clamp the valve plate during testing, then ventilate the valve plate, and place the valve plate in water to observe whether bubbles are generated in the water to judge the quality of the valve plate. It is simple and convenient to operate, unaffected by ambient temperature and humidity, and does not emit radiation.
[0008] Optionally, the lead screw assembly includes a base and a lead screw, the base is fixed to the frame, the lead screw is rotatably engaged with the base, and a fastening nut is provided on the lead screw.
[0009] In this type of lead screw assembly, turning the lead screw can adjust the distance between the first sleeve and the second sleeve. When the fastening nut on the lead screw is turned so that the fastening nut abuts against the base, the lead screw and the base can be temporarily locked, which facilitates the testing of the valve plate.
[0010] Optionally, the frame includes a first base plate, a second base plate, and a support plate. The two ends of the support plate are respectively engaged with the first base plate and the second base plate. There are two support plates, which are parallel and do not contact each other.
[0011] Optionally, the first base plate and the second base plate are parallel to each other, and both the first base plate and the second base plate are provided with reinforcing ribs, and the support plate is engaged with the reinforcing ribs.
[0012] Optionally, the support plate and the reinforcing rib are joined together by fastening screws.
[0013] Optionally, the lead screw assembly is disposed on the first base plate, and the second sleeve is disposed on the second base plate.
[0014] Optionally, the frame is a rectangular frame.
[0015] Optionally, the first guide head is perpendicular to the first gasket, and the second guide head is perpendicular to the second gasket.
[0016] The advantages of this invention are: during testing, the valve plate can be clamped and then ventilated, and the valve plate can be placed in water to observe whether bubbles are generated in the water to judge the quality of the valve plate. The operation is simple and convenient, unaffected by ambient temperature and humidity, and there is no radiation. Attached Figure Description
