Technical Field

[0001] This utility model belongs to the field of floating valve technology, specifically a floating valve. Background Technology

[0002] In modern industrial and civil applications, floating valves are widely used in fluid transport systems such as water supply and drainage systems, petrochemical pipelines, and gas transmission networks due to their excellent sealing performance, flexible opening and closing characteristics, and ability to adapt to different pressure conditions. They achieve floating sealing through a valve disc under the pressure of the medium, effectively controlling the flow and regulating the flow rate of the fluid.

[0003] In practical applications, fluid media often carry various impurities, such as solid particles, rust, and fibrous materials. Once these impurities enter the valve, they will accelerate the wear of key components such as valve seats and valve discs, causing damage to the sealing surface, reducing the sealing performance of the valve, and thus causing media leakage, affecting the normal operation of the system.

[0004] Furthermore, the accumulation of impurities may cause valves to become stuck, preventing them from opening or closing properly. This seriously affects the stability and reliability of the system, increases equipment maintenance costs and downtime for repairs, and causes economic losses.

[0005] Therefore, a floating valve is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, this utility model provides a floating valve, including a floating valve body 1, and a filter assembly 2 is installed at the water inlet end of the floating valve body 1.

[0028] The filter assembly 2 includes a connecting pipe 21. The inlet end of the floating valve body 1 is connected to the connecting pipe 21. A filter disc 22 is installed inside the connecting pipe 21. Multiple snap-fit ​​plates 23 are evenly installed on the outer surface of the filter disc 22. The surface of the connecting pipe 21 has a snap-fit ​​groove 24 corresponding to the snap-fit ​​plate 23. The snap-fit ​​plate 23 snaps into the inside of the snap-fit ​​groove 24. A fixing plate 25 is installed on the outer surface of two snap-fit ​​plates 23. The inside of the connecting pipe 21 has a connecting groove adapted to the fixing plate 25. The fixing plate 25 snaps into the inside of this connecting groove. A ball rod 26 is slidably connected in the cavity opened inside the connecting pipe 21. The ball end of the ball rod 26 is inserted into the insertion hole opened on the surface of the fixing plate 25. A stable connection assembly 3 is installed on the surface of the snap-fit ​​plate 23. This can effectively intercept solid particles, rust and other impurities carried in the fluid, prevent these impurities from entering the inside of the floating valve body 1, thereby significantly reducing the wear of key components such as valve seat and valve disc, and extending the service life of the floating valve body 1.

[0029] Specifically, the front end of the fixing plate 25 is set in an inverted V-shape and fits into the ball end of the ball rod 26, which makes it easy to install the filter disc 22. The filter disc 22 can be fixed in position by simply pushing it in.

[0030] like Figures 1 to 7 As shown, a return spring 27 is sleeved on the surface of the spherical rod 26. One end of the return spring 27 is connected to the spherical rod 26, and the other end of the return spring 27 is installed in the cavity opened inside the connecting pipe 21, so that the operator can easily disassemble and install the filter disc 22.

[0031] Furthermore, the other end of the ball rod 26 passes through the connecting tube 21 and extends to the outside of the connecting tube 21, and is connected to a handle provided on the outside of the connecting tube 21, so that the operator can easily pull the ball rod 26.

[0032] It is worth noting that multiple snap-fit ​​plates 23 are arranged in a circular array with the filter disc 22 as the center.

[0033] like Figures 1 to 7 As shown, the stable connection component 3 includes a rubber pad 31. The rubber pad 31 is inserted into a slot on the surface of the snap-fit ​​plate 23. A positioning strip 32 is installed on the side of the rubber pad 31 away from the center of the connecting pipe 21. A positioning groove adapted to the positioning strip 32 is opened on the surface of the snap-fit ​​plate 23. The positioning strip 32 is inserted into this positioning groove. The rubber pad 31 has good friction, which can improve the connection between the external pipe and the connecting pipe 21 during the pipe connection process, avoid the external pipe from separating from the connecting pipe 21 during use, and facilitate the replacement of the aged rubber pad 31.

[0034] It is worth emphasizing that the positioning strip 32 is designed in a T-shape, which can stabilize the position of the rubber pad 31 and prevent the rubber pad 31 from falling off during use.

[0035] Among them, the structure of the floating valve body 1 is existing technology and is not the main technical point of this patent. Its working principle is a well-known technology, and the appropriate model is selected according to actual use, so it will not be explained in detail.

[0036] Working principle and process: When installing the filter disc 22, first align the filter disc 22 with the connecting pipe 21, so that the snap-fit ​​plate 23 on the outer surface of the filter disc 22 corresponds to the snap-fit ​​groove 24 on the surface of the connecting pipe 21. Push the filter disc 22 so that the snap-fit ​​plate 23 is gradually inserted into the snap-fit ​​groove 24 until the filter disc 22 enters the appropriate position inside the connecting pipe 21. At this time, the two fixing plates 25 also move. When the fixing plate 25 slides in the connecting groove opened inside the connecting pipe 21, since the front end of the fixing plate 25 has an inverted V-shaped structure, when the fixing plate 25 slides, the inverted V-shaped structure will squeeze the ball end of the ball rod 26, so that the ball rod 26 overcomes the elastic force of the return spring 27 and moves into the cavity inside the connecting pipe 21. When the fixing plate 25 is completely snapped into the connecting groove, the ball rod 26 rebounds under the action of the return spring 27, and the ball end is inserted into the insertion hole opened on the surface of the fixing plate 25, thereby achieving a firm fixation of the filter disc 22.

[0037] After the filter disc 22 is installed, insert the external pipe into the port of the connecting pipe 21, and then connect it to the connecting pipe 21 through the flange.

[0038] Fluid containing impurities enters the connecting pipe 21 through the external pipe, and then enters the floating valve body 1 through the connecting pipe 21. When passing through the filter disc 22, the impurities are intercepted by the filter disc 22, while the fluid that meets the requirements continues to flow through the filter holes of the filter disc 22 and then enters the floating valve body 1. According to actual needs, the operator can adjust the flow and flow rate by operating the opening and closing mechanism of the floating valve body 1. During this process, the filter disc 22 is always kept in the connecting pipe 21, continuously filtering the fluid entering the floating valve body 1 to prevent impurities from entering the floating valve body 1 and causing wear and jamming problems.

[0039] When the filter disc 22 needs cleaning or replacement, the connecting pipe 21 is separated from the external pipe via the operating flange. Then, the operator pulls the handle extending from the ball-shaped rod 26 to the outside of the connecting pipe 21, overcoming the spring force of the return spring 27, and pulls the ball end of the ball-shaped rod 26 out of the insertion hole of the fixing plate 25. At this point, the fixing plate 25 loses the restraint of the ball-shaped rod 26. Then, the filter disc 22 is pulled outwards, causing the snap-fit ​​plate 23 to disengage from the snap-fit ​​groove 24, allowing the filter disc 22 to be removed for cleaning or replacement. After cleaning or replacement, the filter disc 22 is reinstalled into the connecting pipe 21 according to the installation procedure.

[0040] During the installation of external pipelines, due to the good friction of the rubber pad 31, the rubber pad 31 fits tightly against the outer wall of the external pipeline, maintaining an effective connection and ensuring the stability of the entire fluid transport system. When it is necessary to replace the aging rubber pad 31, the operator simply pulls the rubber pad 31, causing it to disengage from the slot on the surface of the snap-fit ​​plate 23. As the rubber pad 31 is pulled continuously, it drives the positioning strip 32 to disengage from the positioning groove. Disassembly can be completed without the aid of additional tools. The positioning strip 32 is designed in a T-shape to ensure the stability of the rubber pad 31 during use and to prevent the rubber pad 31 from detaching during use.
