Description

Technical Field

[0001] The utility model relates to the technical field of valve detection, in particular to a nondestructive detection device for valves. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. With the vigorous development of valves in various industries, a valve pressure test detection device is also a major hot topic at present.

[0003] Some traditional water use detection methods may have certain limitations in accuracy and reliability. For example, relying on visual inspection or traditional physical inspection methods may not be able to detect small leaks or valve sealing problems, leading to potential quality problems. Maintaining traditional water use detection equipment usually requires regular inspection and calibration, which may involve high maintenance costs and time costs. Some traditional water use detection methods may be sensitive to specific environmental conditions, such as water pressure, water flow rate or water temperature. In environments where these conditions vary greatly, traditional methods may perform unstably or have poor results. Traditional water inspection puts metal products in water, which will cause rust on the metal products.

[0004] In view of this, there is an urgent need for a non-destructive testing device for valves to improve the deficiencies of the prior art. Utility Model Content

[0007] As a further improvement of the technical solution, a support leg is fixedly connected to the lower surface of the base, and the support leg is used to raise the height of the device for easy operation. A groove is provided on the upper surface of the base, and the clamping assembly slides in the groove.

One end of the air pipe away from the pneumatic push rod is fixedly connected to a detection seat. The inside of the detection seat is hollow. One side of the detection seat is fixedly connected to a detection head, and the detection head is communicated with the detection seat.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] For this non-destructive testing device for valves, air pressure detection can be carried out without contacting the surface of the valve, which means that no physical damage or influence will be caused to the valve itself.

The pneumatic push rod 21 is used to clamp the valve. An air inlet of the pneumatic push rod 21 is fixedly connected to a duct 22. One end of the duct 22 away from the pneumatic push rod 21 is fixedly connected to an air pump 23. The air pump 23 provides power for the pneumatic push rod 21. A clamping component 3 is slidably connected to the upper surface of the base 10. The clamping component 3 includes a clamping bracket 30.

The detection bracket 20 is fixedly connected to the base 10, and a pneumatic push rod 21 is connected to one side. The function of the pneumatic push rod 21 is to clamp the valve to ensure that the valve remains in a fixed position during the detection process. The air inlet of the pneumatic push rod 21 is connected to the air pump 23 at one end far from the pneumatic push rod 21 through a conduit 22. The air pump 23 provides power to the pneumatic push rod 21, thereby realizing the clamping action on the valve. One side of the clamping bracket 30 is connected with a pressure detector 31. The pressure detector 31 is used to monitor the air pressure when clamping the valve to ensure stable air pressure, so as to effectively clamp the valve. At the same time, it is also used to detect whether there is leakage in the valve. The pressure detector 31 continuously monitors the air pressure change during the clamping process. If it is found that the air pressure is unstable or changes abnormally, it may indicate that there is leakage or other problems in the valve. This device can perform non-destructive testing without disassembling the valve, effectively improving the detection efficiency and accuracy, and at the same time reducing the complexity of maintenance and operation.
