Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection devices, and particularly relates to a device for detecting the leakage performance of rubber plates. Background Art

[0002] A rubber plate is a sheet-shaped rubber plate with a certain thickness made of rubber as the main material (which may contain reinforcing materials such as fabric and metal thin plates inside) and vulcanized. Rubber plates generally have relatively high hardness and good physical and mechanical properties, and are widely used. When used as sealing gaskets, sealing rings, sealing strips and other seals, as well as making waterproof materials such as kayaks and floating bladders, it is necessary to detect their water permeability.

[0003] Existing rubber plate leakage detection devices have a series of disadvantages such as the overall bulkiness and heaviness of the detection device, difficulty in observing leakage points, narrow detection pressure range, need to inject water before use, and cumbersome operation. Therefore, it is necessary to develop a more portable, easy-to-operate and easy-to-observe leakage point detection device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies of the existing technology and provide a simple type of floating bladder rubber plate leakage detection device.

[0005] The utility model adopts the following technical solutions:

[0006] A simple type of rubber plate leakage detection device includes a pressure pump, a detection cavity, a pressure transmission pipe connecting the pressure pump and the detection cavity, and a pressure control valve arranged on the pressure transmission pipe; the detection cavity includes a horizontally placed cylinder filled with an aqueous solution of fluorescent agent, a front sealing plate assembly and a rear sealing plate assembly respectively arranged at the front end and the rear end of the cylinder. The front sealing plate assembly is composed of a front cover plate and a flexible silicone rubber pad arranged on the inner end face of the front cover plate. A jack for inserting the pressure transmission pipe is opened at the center of the front cover plate; the rear sealing plate assembly is composed of a rear end cover plate and a detection pressure cover plate arranged on the outer end face of the rear end cover plate. The detection pressure cover plate is detachably connected to the rear end cover plate through bolts passing through the circumference, and a through hole is opened at the center of the rear end cover plate; a detection liquid adding port, a pressure relief valve and a pressure gauge are arranged on the cylinder, and a water permeable hole is opened on the detection pressure cover plate.

[0007] Further, the pressure transmission pipe, the cylinder of the detection cavity, the front cover plate, the rear end cover plate and the detection pressure cover plate are all made of 304 stainless steel.

[0008] Compared with the existing technology, the utility model has at least the following beneficial effects:

[0009] 1. During the use of the utility model, only the rubber plate to be detected needs to be placed between the rear cover plate and the detection pressure cover plate and clamped. There is no need for water filling and drainage. Start the pressure pump to pressurize, and observe through the water permeable holes on the rear cover plate to directly observe whether there is a fluorescent aqueous solution seeping out, so as to judge whether the detected rubber plate has leakage, which is convenient and fast.

[0010] 2. The structure of the utility model is simple and light, convenient to use and carry, and the manufacturing cost is low.

[0011] 3. The whole of the utility model has good sealing performance, can withstand a large detection pressure, has a wide detection range, and high detection accuracy.

[0012] 4. The utility model effectively solves the problems of cumbersome water seepage detection of existing rubber plate products, difficult observation of leakage points, large and bulky detection devices, and narrow detection pressure range. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 is a schematic view of the flexible silicone rubber pad bulging when the pressure pump pressurizes;

[0015] Figure 3 is a right view of the detection pressure cover plate. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The content of the utility model will be further elaborated below in conjunction with the drawings in the specification.

[0017] As Figure 1 shown in the simple rubber plate leakage detection device, which includes a pressure pump 1, a detection cavity 10, a pressure transmission pipe 2 connecting the pressure pump and the detection cavity, and a pressure control valve 3 arranged on the pressure transmission pipe.

[0018] The detection cavity 10 includes a horizontally placed cylinder filled with a fluorescent agent aqueous solution, and a front seal plate assembly and a rear seal plate assembly respectively arranged at the front end and the rear end of the cylinder. The front seal plate assembly is composed of a front cover plate 4 and a flexible silicone rubber pad 5 arranged on the inner end face of the front cover plate. The flexible silicone rubber pad is an impermeable and airtight sealing material, which plays a role in protecting the detection liquid in the cavity and transmitting pressure, and the pressure bearing range reaches 50 MPa. A jack for inserting the pressure transmission pipe 2 is opened in the center of the front cover plate, and the end of the pressure transmission pipe abuts against the flexible silicone rubber pad. The pressure pump can be configured with a suitable range as required, and it can be within the range where the silicone rubber can bear a pressure of up to 50 MPa, which is wider than the range of only 5 MPa of the conventional detection device. The rear seal plate assembly is composed of a rear cover plate 9 and a detection pressure cover plate 11 arranged on the outer end face of the rear cover plate. As Figure 3As shown in the figure, screw holes 11a are evenly distributed around the circumference of the detection pressing cover plate, and corresponding screw holes are also provided on the rear cover plate 9. The rear cover plate and the detection pressing cover plate are detachably connected by bolts 12 passing through the screw holes. A through hole 9a is provided at the center of the rear cover plate. A detection liquid adding port 6, a pressure relief valve 7 and a pressure gauge 8 connected to the pressure relief valve are provided on the cylinder body. A water permeable hole 11b is provided on the detection pressing cover plate 11.

[0019] The pressure transmission pipe 2, the cylinder body of the detection cavity 10, the front cover plate 4, the rear cover plate 9, and the detection pressing cover plate 11 are all made of 304 stainless steel, making the entire device structure stable, with good airtightness, a large pressure-bearing range, and a long service life.

[0020] The pressure pump 1 of the present utility model is the pressurization area, the pressure transmission pipe 2 is the pressure transmission area, and the detection cavity 10 is the detection area. During use, a rubber plate sample to be detected is taken for detection. The sampled rubber plate A is clamped between the rear cover plate 9 and the detection pressing cover plate 11. The exhaust valve 7 is closed, and the pressure pump 1 is started. The generated pressure passes through the pressure transmission pipe 2 to the pressure control valve 3. During the detection process, the required pressure value in the detection area is controlled by the pressure control valve 3. As Figure 2 shown in the figure, the flexible silicone rubber pad 5 is pressed against the protrusion inside the cylinder body by the pressure from the pressure transmission pipe, and the pressure is applied to the fluorescent agent aqueous solution in the detection area. The fluorescent agent aqueous solution passes through the through hole 9a and applies the pressure to the detected rubber plate A. Then, the pressure control valve 3 and the pressure pump 1 are closed, and the pressure inside the cylinder body is maintained for 2 hours. During this period, the rubber plate is irradiated with an ultraviolet lamp to observe whether there is any leakage. If the rubber plate leaks, the phenomenon of the fluorescent agent aqueous solution seeping out can be clearly observed in the water permeable hole 11b. After the test, the pressure inside the cylinder body can be released through the exhaust port 7, and the pressure inside the cylinder body is monitored by the pressure gauge 8. When the fluorescent agent aqueous solution inside the cylinder body is detected to be insufficient after the present utility model has been used for a period of time, it can be added through the detection liquid adding port 6.

[0021] The fluorescent agent aqueous solution adopted by the present utility model is prepared by diluting a commercially available water-based fluorescent agent with water. During the day or at night, the water seepage situation of the rubber plate can be clearly observed through a fluorescent ultraviolet lamp, which is easier to observe than the colorless and transparent water in the conventional detection device. The water-based fluorescent agent aqueous solution inside the cylinder body does not need to be discharged. Through testing, no new water-based fluorescent agent aqueous solution needs to be added within 300 detection times, which is more convenient than the conventional detection device that needs to repeatedly add and discharge the water inside the cavity.
