Description

Technical Field

[0001] This utility model relates to the field of push-button valve technology, and in particular to a quick-install push-button valve. Background Technology

[0002] The push-button valve opens the flow channel by pressing the valve stem of the valve core assembly. When the force is released, a spring pushes the valve stem back to its original position, closing the flow channel. Currently, the valve stem is located in the valve cavity of the valve body, with a sealing ring on its outer wall. When the valve stem is pressed, the sealing ring disengages from the bottom of the valve cavity to open the flow channel. The spring then pushes the valve stem back to its original position, closing the gap between the valve stem and the valve cavity. However, the spring is prone to aging due to repeated deformation, and the sealing ring is prone to wear due to constant friction with the valve cavity, leading to frequent damage to the valve core assembly of the push-button valve. Furthermore, replacing the existing valve core assembly requires disassembling the entire push-button valve, which damages the original sealing structure at the water pipe interface. Reinstalling the push-button valve also requires repairing the sealing structure, making the replacement of the push-button valve quite cumbersome. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a quick-installation push-button valve, which allows for easy replacement of the valve core assembly without damaging the original sealing structure at the water pipe interface of the push-button valve.

[0035] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0036] Reference Figures 1 to 6 As shown, this utility model provides a quick-installation push-button valve.

[0037] The quick-release push valve includes a mounting base 100 and a valve core assembly 200.

[0038] The mounting base 100 has an internal mounting cavity 110, a mounting hole 120 at the top of the mounting base 100 that connects to the mounting cavity 110, an outlet 140 on the side wall of the mounting cavity 110 that connects to the outside, and an inlet 150 at the bottom of the mounting cavity 110 that connects to the outside.

[0039] A first connecting structure 130 is provided on the inner wall of the mounting hole 120.

[0040] The valve core assembly 200 includes a valve body 210, a first sealing ring 220, and a second sealing ring 230.

[0041] The valve body 210 is disposed in the mounting hole 120 and extends into the mounting cavity 110. The outer side wall of the valve body 210 is provided with a second connecting structure 211.

[0042] There are multiple ways in which the first connecting structure 130 and the second connecting structure 211 can be detached and coupled.

[0043] For example, the first connecting structure 130 is a snap-fit ​​on the inner wall of the mounting hole 120, and the second connecting structure 211 is a snap-fit ​​on the outer wall of the valve body 210. The snap-fit ​​and the snap-fit ​​cooperate to achieve detachable snap-fit ​​connection.

[0044] Alternatively, the first connecting structure 130 has a vertical groove and a horizontal groove on the inner wall of the mounting hole 120, with the bottom end of the vertical groove connected to the horizontal groove. The second connecting structure 211 is a slider on the outer wall of the valve body 210, which cooperates with the vertical groove and the horizontal groove. When the slider is in the vertical groove, the valve body 210 can slide up and down relative to the mounting base 100. When the valve body 210 drives the slider to slide down to the horizontal groove, the valve body 210 is rotated to move the slider along the horizontal groove, thereby fixing the valve body 210 in the mounting hole 120 of the mounting base 100.

[0045] Alternatively, the first connecting structure 130 is an internal thread on the inner wall of the mounting hole 120, and the second connecting structure 211 is an external thread on the outer wall of the valve body 210.

[0046] The first sealing ring 220 is detachably fitted onto the outer wall of the valve body 210. The first sealing ring 220 is located on the top of the second connecting structure 211. When the valve body 210 is installed into the mounting hole 120 of the mounting base 100, the first sealing ring 220 seals the gap between the top of the second connecting structure 211 and the top of the first connecting structure 130.

[0047] The second sealing ring 230 is detachably fitted onto the outer wall of the valve body 210. The second sealing ring 230 is located below the first sealing ring 220. When the valve body 210 is installed into the mounting hole 120 of the mounting base 100, the second sealing ring 230 is located between the inlet 150 and the outlet 140, and the second sealing ring 230 seals the gap between the outer wall of the valve body 210 and the inner wall of the mounting cavity 110.

[0048] When the valve core assembly 200 of the quick-release push valve is damaged, the second connecting structure 211 of the valve body 210 and the first connecting structure 130 of the mounting hole 120 on the top of the mounting base 100 are separated, and the valve core assembly 200 can be completely removed. After replacing the internal parts of the valve core assembly 200 or replacing the entire valve core assembly 200, the first sealing ring 220 and the second sealing ring 230 are reinstalled onto the outer wall of the valve body 210. Then, the valve body 210 is reinstalled into the mounting hole 120 on the top of the mounting base 100, so that the second connecting structure 211 of the valve body 210 and the first connecting structure 130 of the mounting hole 120 are engaged. The first sealing ring 220 seals the gap between the first connecting structure 130 and the second connecting structure 211, and the second sealing ring 230 seals the gap between the outer wall of the valve body 210 and the inner wall of the mounting cavity 110.

[0049] Therefore, by adopting a quick-installation push valve, the replacement of the valve core assembly 200 does not require damaging the sealing structure of the original push valve water pipe interface, making the replacement of the valve core assembly 200 more convenient.

[0050] In some embodiments, refer to Figure 3 and Figure 6 As shown, the valve body 210 is provided with a valve cavity 212, which extends through the valve body 210 in the vertical direction. The side wall of the valve cavity 212 is provided with a through hole 213 that connects to the mounting cavity 110. The bottom of the valve cavity 212 connects to the mounting cavity 110. Since the second sealing ring 230 seals the gap between the outer side wall of the valve body 210 and the inner side wall of the mounting cavity 110, the second sealing ring 230 divides the mounting cavity 110 into an upper part and a lower part. The water outlet 140 is located in the upper part, and the water inlet 150 is located in the lower part. The lower part connects to the bottom end of the valve cavity 212, and the through hole 213 connects the valve cavity 212 and the upper part.

[0051] The valve core assembly 200 is also provided with a valve stem 240, a third sealing ring 250, a gland 260 and an elastic element 270.

[0052] The valve stem 240 is slidably disposed in the valve cavity 212. The valve stem 240 slides in the up and down direction, and the third sealing ring 250 is fitted on the outside of the valve stem 240.

[0053] When the valve stem 240 slides upward, the third sealing ring 250 seals the bottom end of the valve cavity 212.

[0054] When the valve stem 240 slides downward, the third sealing ring 250 opens the bottom of the valve chamber 212.

[0055] The top of the pressure cap 260 is detachably connected to the valve stem 240, and the two ends of the elastic element 270 are detachably connected to the pressure cap 260 and the valve body 210 respectively. The elastic force of the elastic element 270 pushes the valve stem 240 to slide upward.

[0056] The valve stem 240 is detachably installed in the valve cavity 212 of the valve body 210. The first sealing ring 220 and the second sealing ring 230 are detachably fitted on the outside of the valve body 210. The third sealing ring 250 is detachably fitted on the outside of the valve stem 240. The gland 260 is detachably connected to the valve stem 240. The elastic element 270 is detachably connected to the gland 260 and the valve body 210.

[0057] Based on the above structure, after the valve body 210 is removed from the mounting hole 120 of the mounting base 100, the first sealing ring 220 and the second sealing ring 230 can be opened and removed from the outside of the valve body 210. Then, the pressure cap 260 is removed from the top of the valve stem 240, so that the elastic element 270 is separated from the pressure cap 260 and the valve body 210. After that, the valve stem 240 is pulled out downward from the bottom end of the valve cavity 212. Then, the third sealing ring 250 is opened and removed.

[0058] The valve body 210, first sealing ring 220, second sealing ring 230, valve stem 240, third sealing ring 250, gland 260 and elastic element 270 of the valve core assembly 200 are all detachable components, so that any of the above components can be replaced, and any component of the entire valve core assembly 200 can be replaced and reinstalled for use.

[0059] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the bottom end of the valve stem 240 is provided with an outwardly protruding part 241. The outwardly protruding part 241 protrudes radially from the valve stem 240 and extends below the valve cavity 212. The outer diameter of the outwardly protruding part 241 is larger than the diameter of the bottom end of the valve cavity 212. When the top of the outwardly protruding part 241 abuts against the bottom end face of the valve cavity 212, the valve stem 240 cannot continue to slide upward.

[0060] The elastic force of the elastic element 270 pushes the valve stem 240 to move upward, and the outward protrusion 241 prevents the valve stem 240 from disengaging from the valve cavity 212 upward, thereby ensuring that the third sealing ring 250 on the valve stem 240 can seal the bottom end of the valve cavity 212.

[0061] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the valve core assembly 200 is also provided with a fourth sealing ring 280. The third sealing ring 250 is installed on the top of the protrusion 241, and the fourth sealing ring 280 is sleeved on the outside of the valve stem 240, with the fourth sealing ring 280 located above the third sealing ring 250.

[0062] The third sealing ring 250 is pressed upward by the protruding part 241 to seal the bottom end face of the valve cavity 212, while the fourth sealing ring 280 is located inside the valve cavity 212 and seals the gap between the inner wall of the valve cavity 212 and the outer wall of the valve stem 240.

[0063] During the up-and-down sliding process of the valve stem 240, there is no relative friction between the third sealing ring 250 and the valve cavity 212, which can avoid leakage problems caused by wear of the third sealing ring 250 and improve service life.

[0064] If the third sealing ring 250 has not yet sealed the bottom of the valve chamber 212, the fourth sealing ring 280 can pre-seal the valve chamber 212 to improve the response speed of the push valve closing. Even if the fourth sealing ring 280 is worn, it can still provide the effect of blocking more fluid. The sealing of the bottom of the valve chamber 212 is achieved by the third sealing ring 250.

[0065] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the bottom of the pressure cap 260 is provided with a screw hole 261, and the top of the valve stem 240 is provided with a screw 242. The screw hole 261 and the screw 242 are threaded together.

[0066] The gland 260 is provided with a screw hole 261 that fits into the screw 242 of the valve stem 240, which makes it easier to install and remove the gland 260.

[0067] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, an anti-rotation groove 243 is provided on the bottom end face of the valve stem 240.

[0068] After removing the valve core assembly 200 from the mounting base 100, insert a screwdriver into the anti-rotation groove 243, and then rotate the pressure cap 260 to make the screw hole 261 of the pressure cap 260 rotate relative to the screw 242 of the valve stem 240, thereby tightening or loosening the pressure cap 260 and the valve stem 240.

[0069] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the first connecting structure 130 has an internal thread, and the second connecting structure 211 has an external thread.

[0070] The external thread on the outer side wall of the valve body 210 matches the internal thread of the mounting hole 120 of the mounting base 100, making the valve body 210 and the mounting hole 120 fit more tightly and making it easier to disassemble and assemble.

[0071] In some embodiments, refer to 2, Figure 3 , Figure 5 , Figure 6 As shown, a step 214 is provided on the outer wall of the valve body 210. The step 214 extends to the outer periphery of the valve body 210 and is located above the first connecting structure 130. The first sealing ring 220 is sleeved on the outside of the valve body 210 and is located at the bottom of the step 214. When the valve body 210 is threadedly engaged with the first connecting structure 130 of the mounting hole 120 through the second connecting structure 211, the step 214 presses down on the first sealing ring 220 so that the outer wall of the first sealing ring 220 abuts against the top of the first connecting structure 130, thereby sealing the top of the first connecting structure 130 and the top of the second connecting structure 211.

[0072] The step 214 is used to press the first sealing ring 220 to ensure the sealing effect of the first sealing ring 220 on the top of the first connecting structure 130 and the top of the second connecting structure 211.

[0073] In some embodiments, refer to 2, Figure 3 , Figure 5 , Figure 6 As shown, the top edge of the mounting hole 120 is chamfered 121.

[0074] During the process of valve body 210 being threaded into first connecting structure 130 of mounting hole 120 using second connecting structure 211, step 214 pushes first sealing ring 220 to gradually press against the top edge of mounting hole 120, chamfer 121 guides first sealing ring 220, so that first sealing ring 220 is gradually pressed down along chamfer 121 and pressed tightly against the top of first connecting structure 130, avoiding scratching first sealing ring 220 by top edge of mounting hole 120, and first sealing ring 220 pressed by chamfer 121 provides better sealing effect for first connecting structure 130.

[0075] In some embodiments, refer to Figure 2 and Figure 5 As shown, the outer wall of the valve body 210 is provided with an outwardly protruding anti-rotation surface 215. The anti-rotation surface 215 extends vertically and there are multiple anti-rotation surfaces 215. The multiple anti-rotation surfaces 215 form a polygon on the outer wall of the valve body 210. The anti-rotation surface 215 is located above the second connecting structure 211.

[0076] The valve body 210 utilizes the second connecting structure 211 threaded into the first connecting structure 130 of the mounting hole 120 of the mounting base 100. By using a wrench to abut against the anti-rotation surface 215, the valve body 210 is rotated relative to the mounting base 100, which facilitates the assembly and disassembly of the valve body 210 from the mounting hole 120.

[0077] In some embodiments, refer to Figures 1 to 6 As shown, a quick-connect pipe 160 is provided on the outer wall of the mounting base 100, and the quick-connect pipe 160 is connected to the water inlet 150.

[0078] In some embodiments, refer to Figures 1 to 3 As shown, another quick-connect pipe 160 is also provided to connect to the water outlet 140.

[0079] The outer wall of the quick-connect pipe 160 is provided with an annular groove 161, which surrounds the circumference of the quick-connect pipe 160.

[0080] When the mounting base 100 is connected to the water pipe using the quick-connect pipe 160, the quick connector can be sleeved on the quick-connect pipe 160. The elastic buckle of the quick connector is engaged in the annular groove 161, so that the quick-connect pipe 160 and the quick connector are connected and communicated.

[0081] In some embodiments, refer to Figures 1 to 6 As shown, the quick-release push valve is also equipped with a pressure ring 300 and a fifth sealing ring 290.

[0082] Reference Figures 2 to 3 As shown, the outer wall of the pressure ring 300 is provided with external threads, and the middle part of the pressure ring 300 is provided with a clearance hole. The clearance hole of the pressure ring 300 is sleeved on the outside of the valve stem 240. The fifth sealing ring 290 is sleeved on the outside of the valve stem 240. The top of the valve body 210 is provided with an assembly hole, which is located above the valve cavity 212. The inner wall of the assembly hole is provided with internal threads. The pressure ring 300 is threaded into the assembly hole. The fifth sealing ring 290 is located below the pressure ring 300. The pressure ring 300 presses the fifth sealing ring 290 downward between the outer wall of the valve stem 240 and the top of the valve cavity 212. The fifth sealing ring 290 seals the gap between the outer wall of the valve stem 240 and the top of the valve cavity 212.

[0083] The bottom end of the elastic element 270 abuts against the top of the pressure ring 300, and the top end of the elastic element 270 abuts against the pressure cap 260.

[0084] Reference Figure 5 and Figure 6 As shown, the pressure ring 300 is also fitted onto the outside of the valve stem 240 through the clearance hole, and the fifth sealing ring 290 is also fitted onto the outside of the valve stem 240, with the fifth sealing ring 290 positioned below the pressure ring 300. The difference lies in that the bottom end of the elastic element 270 abuts against the top of the pressure ring 300, and the top end of the elastic element 270 abuts against the pressure cap 260. The elastic force of the elastic element 270 pushes the pressure ring 300 downward to compress the fifth sealing ring 290.

[0085] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
