Description

Technical Field

[0001] The utility model belongs to the technical field of filter production and detection, in particular to an automatic filter leakage detection device. Background Art

[0002] Y-type filter is an indispensable filtering device for the pipeline system of conveying medium. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve or other equipment to remove impurities in the medium to protect the normal use of valves and equipment. Y-type filter needs to be leak tested after production to prevent leakage when Y-type filter is installed on the pipeline. Due to its special structure, Y-type filter has the following disadvantages when leak testing:

[0003] 1. The drain port on the Y-type filter is generally welded to the filter body, so there will be a weld between the drain port and the body. The weld is very prone to leakage and needs to be tested. At present, it is generally tested by adding water inside. The sealing of the weld is tested by observing whether there is leakage at the weld. However, the detection method of filling the Y-type filter with liquid not only has an insignificant detection effect, but also easily pollutes the inside of the Y-type filter;

[0004] 2. After the existing Y-type filter is produced, its shell is often stained with oil during the production and processing process, which will affect the appearance of the Y-type filter, so the outer wall of the Y-type filter needs to be cleaned. Utility Model Content

[0005] The utility model aims to provide an automatic filter leak detection device, which inputs compressed air into a Y-type filter through an air pipe to generate positive pressure inside the Y-type filter and sprays soapy water on the surface of the Y-type filter. When there is a leak point on the Y-type filter, the leak point will spray air, and the sprayed air will cause the soapy water on the surface of the leak point to generate bubbles, thereby solving the problem that the existing detection method of filling liquid into the Y-type filter has an unclear detection effect.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses an automatic filter leak detection device, comprising a bottom plate, a hydraulic telescopic column is fixedly installed on the upper end of the outer wall of the bottom plate, a spray frame is fixedly installed on the upper end of the outer wall of the hydraulic telescopic column, a connecting pipe is fixedly installed on the upper end of the outer wall of the spray frame, a supporting column is fixedly installed on the front side of the upper end of the outer wall of the bottom plate, a connecting plate is fixedly installed on the upper end of the outer wall of the supporting column, a soapy water storage tank is placed on the upper end of the outer wall of the connecting plate, and the upper end of the outer wall of the connecting pipe is connected with the soapy water storage tank.

[0010] Furthermore, a Y-type filter is placed on the arc-shaped bracket, a weld is provided in the middle of the Y-type filter, and the left and right openings of the Y-type filter are both detachably connected with connecting flanges, an air pipe is fixedly installed on the left side of the outer wall of the left connecting flange, and an air pressure gauge is fixedly installed on the right side of the outer wall of the right connecting flange, and a flange cover is detachably connected to the sewage outlet of the Y-type filter.

[0011] Furthermore, spray head 1 is symmetrically fixedly connected to the left and right sides of the lower end of the outer wall of the spray frame, spray head 2 is fixedly connected to the rear side of the lower end of the outer wall of the spray frame, and arc-shaped spray head 3 is fixedly connected to the front end of the spray head 2 under the outer wall of the spray frame.

[0012] Furthermore, the projection of the weld at the lower end of the outer wall of the spray frame overlaps with the arc-shaped spray head three, the projection of the connecting flanges on the left and right sides overlaps with the spray head one at the lower end of the outer wall of the spray frame, and the projection of the flange cover at the lower end of the outer wall of the spray frame overlaps with the spray head two.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model inputs compressed air into the Y-type filter through the air pipe, so that positive pressure is generated inside the Y-type filter, and soapy water is sprayed on the surface of the Y-type filter. When there is a leakage point on the Y-type filter, the leakage point will spray air, and the sprayed air will cause the soapy water on the surface of the leakage point to produce bubbles. The inspector can judge whether the Y-type filter will leak by observing whether bubbles are generated on the surface of the Y-type filter. The device has obvious detection effect, and the detection result is convenient for the inspector to observe and find. At the same time, because the medium used for detection by the device is compressed air, the internal structure of the filter will not be contaminated during the detection process.

[0017] 2. When the utility model is in use, after the test is completed, the tester can clean the surface of the Y-type filter by using the nozzle by turning on the pump. At the same time, the soapy water on the surface of the Y-type filter can increase the cleaning effect on the oil stains, thereby increasing the practicality of the device.
