Description

Technical Field

[0001] This utility model relates to the field of mechanical seals, and in particular to an explosion-proof cleaning controller with a sealing structure. Background Technology

[0002] In the existing technology, the explosion-proof cleaning controller is an automated control device designed specifically for flammable and explosive hazardous environments, used to achieve intelligent control of various cleaning methods such as high-pressure cleaning, ultrasonic cleaning, and chemical cleaning.

[0003] A filter pressure reducing valve is installed in the control cabinet of the explosion-proof cleaning controller. Figure 1 This is a schematic diagram of a filter pressure reducing valve with an L-shaped plate in the prior art. Figure 2 This is a schematic diagram of a filter pressure reducing valve in the prior art without the L-shaped plate installed. Figure 3 for Figure 2 An enlarged view of part A in the image. (See image below.) Figures 1 to 3 As shown, this is a typical filter pressure reducing valve 10 on the market. The boss 11 is connected to the thread 20, and there is only a 0.1 mm distance between the boss 11 and the outer contour 12.

[0004] Figure 4 This is a schematic diagram of the structure of an explosion-proof cleaning controller in the prior art. (Example:) Figure 4 As shown, the filter pressure reducing valve 10 has a boss 11 and uses a mechanical seal with the control cabinet 30, for example, sealing from the outside to the inside through a gasket 13, a mounting plate 14, and an O-ring 15. Because the gap between the boss 11 and the outer contour 12 is small, the contact area of ​​the gasket 13 is small, and the gasket 13 is easy to fall off, which makes it difficult for the filter pressure reducing valve 10 to seal.

[0005] Here, the mounting plate 14 is preferably an L-shaped plate (e.g., Figure 1 As shown in the diagram, the L-shaped plate mates with the boss 11 to prevent rotation. Simultaneously, the L-shaped plate serves as a transition joint. Therefore, the L-shaped plate is essential in this application, but it also complicates sealing. Existing technologies do not require sealing and therefore do not present this technical problem.

[0006] Therefore, the gasket 13 is difficult to seal effectively, and water can easily enter the threads of the mounting nut 16 and then enter the control cabinet 20 through the threads. Especially after transportation or a period of use, even slight movement of the gasket 13 can lead to poor sealing.

[0007] In view of this, the inventors of this application have designed an explosion-proof cleaning controller with a sealed structure in order to solve the above-mentioned technical problems. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defects of the existing technology where the air filter is installed in the electrical control cabinet, and the poor sealing performance due to the boss structure makes it easy for water to enter. The present invention provides an explosion-proof cleaning controller with a sealing structure.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] An explosion-proof cleaning controller with a sealing structure is characterized in that the explosion-proof cleaning controller includes a control cabinet, a valve body, a sealing ring and fasteners, a mounting hole is opened on the wall of the control cabinet, the valve body has a threaded area, the valve body passes through the mounting hole, and a sealant is applied to the threaded area, the sealant being located between the threaded area and the mounting hole;

[0011] The sealing ring is installed at the connection between the valve body and the control cabinet, located on the upper end face of the mounting hole. The fastener is installed on the valve body, pressing the sealing ring against the wall surface of the mounting hole from top to bottom.

[0012] According to one embodiment of the present invention, the vertical width of the sealant applied to the threaded area exceeds the height of the mounting hole.

[0013] According to one embodiment of the present invention, a step is provided below the threaded area of ​​the valve body, and a mounting plate is provided between the step and the mounting hole.

[0014] According to one embodiment of the present invention, the mounting plate is connected to the boss on the valve body in a shape that matches each other, and the boss is located between the threaded area and the step.

[0015] According to one embodiment of the present invention, the mounting plate presses against the wall surface at the mounting hole.

[0016] According to one embodiment of the present invention, the fastener is a threaded fastener.

[0017] According to one embodiment of the present invention, the upper end to the lower end of the connecting hole of the threaded fastener is covered with threads.

[0018] According to one embodiment of the present invention, the sealing ring is an O-ring.

[0019] According to one embodiment of the present invention, the valve body is a filter pressure reducing valve.

[0020] According to one embodiment of the present invention, both the sealing ring and the fastener are located inside the control cabinet.

[0050] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0051] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0052] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0053] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0054] like Figures 5 to 7 As shown, this utility model discloses an explosion-proof cleaning controller with a sealing structure, including a control cabinet 100, a valve body 200, a sealing ring 300, and fasteners 400. A mounting hole 110 is formed on the wall of the control cabinet 100, and the valve body 200 has a threaded region 210, which passes through the mounting hole 110. The valve body 200 is preferably a filter pressure reducing valve. Sealant is applied to the threaded region 210, such that the sealant is located between the threaded region 210 and the mounting hole 110.

[0055] Preferably, such as Figure 6As shown, the vertical width of the sealant applied to the threaded area 210 exceeds the height of the mounting hole 110. That is, the upper part of the sealant extends beyond the upper part of the mounting hole (e.g., 2-3 mm beyond the upper part of the mounting hole), and the lower part of the sealant extends beyond the lower part of the mounting hole (e.g., 2-3 mm beyond the lower part of the mounting hole).

[0056] A sealing ring 300 is installed at the connection between the valve body 200 and the control cabinet 100, located on the upper end face of the mounting hole 110. Fasteners 400 are installed on the valve body 200, pressing the sealing ring 300 against the wall surface of the mounting hole 110 from top to bottom. For example, in this embodiment, the wall surface of the mounting hole 110 is the bottom surface of the control cabinet 100. In this embodiment, the sealing ring 300 is preferably an O-ring.

[0057] Preferably, a step 220 is provided below the threaded area 210 of the valve body 200, and a mounting plate 500 is provided between the step 220 and the mounting hole 110. The shape of the mounting plate 500 matches the shape of the boss 230 on the valve body 200, so that the boss 230 is located between the threaded area 210 and the step 220. The mounting plate 500 presses against the wall surface at the mounting hole 110.

[0058] The mounting plate 500 and the boss 230 are fitted together to form flat surfaces on both the top and bottom, filling the gaps between the top and bottom surfaces of the boss 230. This ensures that the control cabinet 100, the sealing ring 300, and the mounting plate 500 are in surface contact, achieving a planar seal and preventing water ingress from the threaded area and the mounting hole.

[0059] In addition, the cooperation between the mounting plate 500 and the boss 230 can also prevent the valve body from rotating, and the mounting plate 500 can press the bottom surface of the control cabinet 100 to assist in the sealing function.

[0060] like Figure 7 As shown, fastener 400 is preferably a threaded fastener. The upper and lower ends of the connecting hole of the threaded fastener are fully threaded. Compared to the structure of the standard nut 600 on the valve body, the fastener 400 has a longer effective thread. The lower part 610 of the threaded hole of the standard nut 600 on the valve body is smooth and unthreaded. Therefore, the structure of the fastener 400 in this application exerts greater pressure on the sealing ring 300, which is more conducive to sealing.

[0061] In this application, both the sealing ring 300 and the fastener 400 are preferably located inside the control cabinet 100. The sealing ring 300 is disposed between the wall of the control cabinet 100 and the fastener 400, and sealant is applied to the threaded area of ​​the fastener 400, covering the area between the mounting hole and the threaded area. This double-structure seal ensures that the threaded area is sealed from water ingress, while the mounting hole is also sealed from water ingress.

[0062] According to the above structural description, the sealing process of the explosion-proof cleaning controller with sealing structure of this utility model is as follows: when water flows into the valve body 200 (e.g., a filter pressure reducing valve), liquid sealant seals the threads of the valve body 200. The inner sealing ring 300 seals the planes of the mounting plate 500 and the control cabinet 100.

[0063] The thread of the fastener 400 (i.e., non-standard nut) used in this application is 2 mm longer than the thread of the mounting nut attached to the valve body 200 (e.g., a filter pressure reducing valve). Because the conventional sealing gasket is removed, the valve body 200 (e.g., a filter pressure reducing valve) can penetrate deeper into the control cabinet 100, and the thread of the fastener 400 (i.e., non-standard nut) can be fully tightened to achieve an effective seal.

[0064] The above-mentioned structure of this application has been tested for sealing and can achieve IP65, thus realizing the sealing of this filter pressure reducing valve with boss on the control cabinet.

[0065] In summary, the explosion-proof cleaning controller with a sealing structure of this utility model can improve the sealing of the entire structure by adding sealant to the threads, adding an O-ring between the light hole and the filter pressure reducing valve in the electrical control cabinet, and installing the O-ring inside the control cabinet and using the method of tightening the threaded parts.

[0066] The explosion-proof cleaning controller with a sealing structure can improve the sealing performance of the filter pressure reducing valve with a boss mounted on the electrical control cabinet.
