Description

Technical Field

[0001] This utility model relates to the field of water inlet valve technology, specifically a water inlet valve with an expansion rubber strip. Background Technology

[0002] The rubber strip of the rubber-strip inlet valve is made with a special formula, possessing excellent elasticity, wear resistance, and corrosion resistance. Under fluid pressure, the rubber strip expands moderately, tightly fitting the valve seat to form an indestructible sealing barrier. This characteristic allows the expandable rubber-strip inlet valve to maintain excellent sealing performance even under harsh operating conditions, effectively preventing leakage.

[0003] Existing rubber strips are typically glued to the sealing surface of the inlet valve, or placed in an annular groove created on the sealing surface. While gluing ensures a tight bond between the rubber strip and the valve's sealing surface, it presents several inconveniences during disassembly and assembly. The strong adhesive force after the glue cures makes it difficult to remove the rubber strip completely, often resulting in damage or residue, increasing the difficulty and cost of replacement. While placing the rubber strip in an annular groove avoids the curing problems associated with glue, the rubber strip is placed within the groove, requiring specialized tools for prying during disassembly. This not only easily damages the rubber strip and the groove's edges but may also damage the overall structure of the inlet valve. Utility Model Content

The end of the return spring away from the receiving groove is fixedly connected to the mounting groove. The top plate is slidably connected to the mounting groove. A round shaft is slidably connected through both sides of the sealing disc. A pressure plate is fixedly connected to the end of each round shaft away from the sealing disc. A compression spring is sleeved on each round shaft. One end of the compression spring is fixedly connected to the outer wall of the sealing disc, and the end of the compression spring away from the sealing disc is fixedly connected to the pressure plate. A compression block is fixedly connected to the end of each round shaft away from the pressure plate. A compression groove is provided on the top plate corresponding to the compression block. A rubber strip is sleeved on the side of the mounting groove near the top plate.

[0006] Preferably, one side of the extrusion block is designed with an inclined structure, the extrusion groove is designed with an inclined structure, and the extrusion block and the extrusion groove are slidably connected.

[0017] 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.

[0018] Please see Figure 1-5This utility model provides a technical solution: a water inlet valve with an expansion rubber strip, including a water inlet valve 1 and a top plate 2. Sealing discs 3 are fixedly connected to both sides of the water inlet valve 1. Mounting grooves 4 are opened on both sides of the sealing discs 3. A symmetrically arranged receiving groove 5 is opened on one side of the top plate 2. A return spring 6 is fixedly connected to each receiving groove 5. The end of the return spring 6 away from the receiving groove 5 is fixedly connected to the mounting groove 4. The top plate 2 is slidably connected to the mounting groove 4. A round shaft 7 is slidably connected through both sides of the sealing discs 3. A pressure plate 8 is fixedly connected to the end of the round shaft 7 away from the sealing discs 3. A compression spring 9 is sleeved on each round shaft 7. One end of the compression spring 9 is fixedly connected to the outer wall of the sealing disc 3, and the end of the compression spring 9 away from the sealing disc 3 is fixedly connected to the pressure plate 8. A compression block 10 is fixedly connected to the end of the round shaft 7 away from the pressure plate 8. A compression groove 11 is opened on the top plate 2 corresponding to the compression block 10. A rubber strip 12 is sleeved on the side of the mounting groove 4 near the top plate 2.

[0019] The extrusion block 10 has an inclined structure on one side, and the extrusion groove 11 has an inclined structure. The extrusion block 10 and the extrusion groove 11 are slidably connected, which facilitates the extrusion block 10 to extrude the extrusion groove 11. The pressure plate 8 has an arc-shaped structure, and the arc of the pressure plate 8 is consistent with the arc of the sealing disc 3, which facilitates the extrusion of the pressure plate 8. The pressure plate 8 drives the circular shaft transmission. The sealing disc 3 has a placement groove corresponding to the extrusion block 10. The extrusion block 10 is slidably connected to the placement groove, which facilitates the transmission of the extrusion block 10. The rubber strip 12 is an expanded rubber strip with an annular structure design, which facilitates the increase of sealing performance through the rubber strip 12.

[0020] Specifically, when using this utility model, the rubber strip 12 is fitted into the mounting groove 4 and made to fit tightly against the top plate 2. When it is necessary to remove the rubber strip 12, both hands press the pressure plate 8 at the same time. The pressure plate 8 then drives the extrusion block 10 to move through the round shaft 7. The moving extrusion block 10 then extrudes the extrusion groove 11 opened in the top plate 2. The extruded top plate 2 then moves away from the mounting groove 4. The moving top plate 2 then pushes the rubber strip 12 outward from the mounting groove 4. At this time, the rubber strip 12 can be completely removed. After removal, stop pressing the pressure plate 8. At this time, the extrusion spring 9 drives the pressure plate 8 to reset. The reset pressure plate 8 then drives the extrusion block 10 to reset through the round shaft 7. The top plate 2, which is no longer extruded, then resets under the traction of the reset spring 6.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
