Description

Technical Field

[0001] This invention relates to the field of valve technology, and more particularly to a valve with a quick-connect fitting. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. However, traditionally, valves installed externally are mostly connected through flanges or flange-like components. A flange has multiple bolt holes, and workers need to install bolts into each bolt hole one by one. This requires workers to carry a lot of construction tools, and the process of installing bolts one by one consumes a lot of time and manpower, thus prolonging the pipeline installation process.

[0003] The utility model patent with authorization announcement number CN204805677U discloses a water valve with a quick-connect coupling. However, when the valve is connected to other pipes by thread, it is necessary to rotate the valve itself continuously for installation. When the valve is heavy, the installation and connection become very troublesome. In particular, after connecting one end of the valve, the other end can only be installed by rotating the pipe. Therefore, there is a need for a valve that can be connected to other pipes by simply rotating the coupling. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a valve with a quick-connect fitting, which can be connected to other pipes by means of a rotary fitting alone.

[0005] The technical solution adopted by the present invention to solve its technical problem is a valve with a quick-connect coupling, including a valve body with a water passage and a switch assembly disposed on the valve body for opening or closing the water passage. A first boss is provided on the outer surface of one end of the valve body, and a connector body is connected to one end of the valve body. The connector body has a connector through hole communicating with the water passage. The connector body is provided with a first buckle that engages with the first boss so that the connector body can rotate relative to the first boss. A groove is provided on the inner side wall of the connector body. A connecting cylinder is connected inside the connector body. A second buckle is provided on the outer peripheral surface of the connecting cylinder near the valve body that engages with the groove. The connecting cylinder is provided with a threaded structure.

[0006] As a further improvement of the present invention, the connecting cylinder is also provided with an elastic sealing element for sealing the gap between the connecting cylinder and the first boss.

[0007] As a further improvement of the present invention, the inner sidewall of the connector body is also provided with a first groove that communicates with the slot and has an inner diameter smaller than the inner diameter of the slot, and an opening is provided above the first groove.

[0008] As a further improvement of the present invention, the outer peripheral surface of the connecting cylinder is also provided with a mating protrusion, and the second buckle is integrally disposed on the mating protrusion, and the width of the first groove is greater than the width of the second buckle.

[0009] As a further improvement of the present invention, the first buckle is arranged in a funnel-shaped ring on the inner side wall of the connector body, and the first buckle is provided with a plurality of second grooves at intervals.

[0010] As a further improvement of the present invention, the outer peripheral surface of the connector body is provided with connector protrusions corresponding to the slot positions.

[0011] As a further improvement of the present invention, the thread structure is an internal thread, and the outer peripheral surface of the elastic seal is provided with a number of elastic bosses that can be engaged with the internal thread of the connecting cylinder.

[0012] As a further improvement of the present invention, a second protrusion is provided at one end of the valve body near the connector body, and a first buckle is engaged between the first protrusion and the second protrusion.

[0013] As a further improvement of the present invention, the inner sidewall of the valve body is provided with a mounting boss and a mounting through hole. The switching assembly includes a valve core disposed in the valve body and a valve handle inserted into the mounting through hole and detachably connected to the valve core. The valve core abuts against the mounting boss.

[0014] As a further improvement of the present invention, the outer peripheral surface of the valve body is provided with an annular groove, and the valve handle is provided with a valve handle protrusion inserted into the annular groove.

[0015] The beneficial effects of the present invention are at least as follows:

[0016] 1. When the connector body rotates, it will not cause the valve body to rotate synchronously, so that the connection between the valve body and the connector body will not loosen no matter how the connector body rotates. The upper part of the connector body can be connected to other pipes or faucets through the threaded structure of the connecting sleeve. Therefore, when the connector body is rotated for installation, the valve body will not rotate, making installation convenient and quick. The connecting sleeve is snapped into the connector body, eliminating the need for ultrasonic connection. Ultrasonic testing can easily damage the product, and a water test is required to check the seal after ultrasonic testing. This application can reduce production process steps, lower costs, and facilitate the replacement of damaged parts. Furthermore, the specifications of the connecting sleeve can be selected and changed according to the pipe diameter, making the entire structure more interchangeable. After installation, the upward direction of the connecting sleeve is blocked by the inner wall of the slot, and the downward direction is blocked by the valve body, ensuring both convenient installation and a stable connection structure.

[0017] 2. The use of elastic seals can improve sealing performance, increase contact area, reduce pressure, and reduce wear on the connecting cylinder.

[0018] 3. It has an upward-facing first groove, so that when installing the connecting cylinder, the second buckle can be installed downward along the first groove, thus being directly installed in the slot, which has the functions of preventing mistakes, positioning and guiding.

[0019] 4. The width of the first groove is greater than the width of the second buckle, so that the connecting cylinder will not deflect when it is inserted into the connector body, thereby preventing the second buckle from coming out; the second buckle is integrally set on the mating protrusion, and the mating protrusion contacts the inner wall of the first groove, increasing the contact area and improving the stability of the connecting cylinder.

[0020] 5. The flared design allows for quick and easy connection, stable fit, and the spaced second grooves enhance the elasticity of the first buckle.

[0021] 6. The upper part of the connector body can be connected to pipe structures such as faucets through the threaded structure of the connecting cylinder. During installation or disassembly, the connector body needs to be rotated. The design of the connector protrusion can increase the contact area of ​​the user's hand, making it easier to apply force. Since the design of the slot and the first groove will reduce the thickness of the side wall of the connector body, the connection of the connector protrusion with the slot can increase the wall thickness, thereby improving the stability and life of the product.

[0022] 7. The connecting cylinder adopts an internal thread connection. During installation, inserting the connecting pipe above the connecting cylinder will press it against the elastic seal, thereby achieving a sealing effect. The elastic boss allows the elastic seal to be engaged with the internal thread, and due to its elasticity, a larger force can be used to install or remove the elastic seal.

[0023] 8. The second boss can provide a limiting function, and a double-buckle structure can be set as needed to snap onto the first boss and the second boss respectively, further improving the stability of the fit.

[0024] 9. The water passage can be opened or closed by rotating the valve handle. The valve core adopts a ball valve and is detachably connected to the valve body. Existing switching components have bosses on both the upper and lower sides of the valve core for locking. This application only has a mounting boss on one side of the valve core to achieve detachable installation of the valve core and improve product compatibility.

[0025] 10. The valve handle protrusion is inserted into the annular groove, which can provide positioning and limiting functions to prevent the valve handle from rotating too much or too little, resulting in the failure to open or close the water passage smoothly.

[0026] 11. The guide slope provides guidance and increases the thickness of the inner wall of the slot, improving the stability of the connection; the guide slope makes the inner diameter of the first groove smaller and smaller, thereby increasing the depth difference between the slot and the first groove, making the first buckle more difficult to disengage.

[0033] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in this invention are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0035] Reference Figure 1-6This invention proposes a valve with a quick-connect fitting, comprising a valve body 2 having a water passage 1 and a switch assembly 3 disposed on the valve body 2 for opening or closing the water passage 1. A first boss 21 is provided on the outer surface of one end of the valve body 2, and a connector body 4 is connected to one end of the valve body 2. The connector body 4 has a connector through hole 41 communicating with the water passage 1. The connector body 4 has a first buckle 42 that engages with the first boss 21, allowing the connector body 4 to rotate relative to the first boss 21. A groove 43 is provided on the inner side wall of the connector body 4, and a connecting cylinder 5 is connected inside the connector body 4. The connecting cylinder 5 has a second buckle 51 on its outer peripheral surface near the valve body 2 that engages with the groove 43. The connecting cylinder 5 has a threaded structure. When the connector body 4 rotates, it will not cause any... The valve body 2 rotates synchronously, ensuring that the connection between the valve body 2 and the connector body 4 will not loosen regardless of the rotation of the connector body 4. The upper part of the connector body 4 can be connected to other pipes or faucets through the threaded structure of the connecting sleeve 5. Therefore, the valve body 2 will not rotate when the connector body 4 is rotated for installation, making installation convenient and quick. The connecting sleeve 5 is snapped into the connector body 4, eliminating the need for ultrasonic connection, reducing production process steps, lowering costs, and making it easy to replace damaged parts. Furthermore, the specifications of the connecting sleeve 5 can be selected and changed according to the pipe diameter, making the entire structure more interchangeable. After installation, the upward direction of the connecting sleeve 5 is blocked by the inner wall of the slot 43, and the downward direction is blocked by the valve body 2, ensuring both convenient installation and a stable connection structure.

[0036] Reference Figure 2 and Figure 3 The connecting cylinder 5 is also provided with an elastic sealing element 6 for sealing the gap between the connecting cylinder 5 and the first boss 21; the setting of the elastic sealing element 6 can improve the sealing performance, increase the contact area, reduce pressure, and reduce the wear on the connecting cylinder 5.

[0037] Reference Figure 2-6 The inner wall of the connector body 4 is also provided with a first groove 44 that communicates with the slot 43 and has an inner diameter smaller than that of the slot 43. An opening is provided above the first groove 44. With the first groove 44 facing upward, the second buckle 51 can be installed downward along the first groove 44 when the connecting cylinder 5 is installed, so that it can be directly installed in the slot 43, which has the functions of preventing mistakes, positioning and guiding.

[0038] Reference Figure 2 and Figure 3The outer peripheral surface of the connecting cylinder 5 is also provided with a mating protrusion 52, and the second buckle 51 is integrally set on the mating protrusion 52. The width of the first groove 44 is greater than the width of the second buckle 51. The width of the first groove 44 is greater than the width of the second buckle 51, so that when the connecting cylinder 5 is inserted into the connector body 4, the connecting cylinder 5 will not deflect, thereby preventing the second buckle 51 from coming out. The second buckle 51 is integrally set on the mating protrusion 52, and the mating protrusion 52 contacts the inner sidewall of the first groove 44, increasing the contact area and improving the stability of the connecting cylinder 5.

[0039] Reference Figure 4 and Figure 5 The first buckle 42 is arranged in a funnel shape on the inner side wall of the connector body 4. The first buckle 42 is provided with several second grooves 421 at intervals. The funnel shape makes the connection quick and convenient and the fit stable. The spaced second grooves 421 can improve the elasticity of the first buckle 42.

[0040] Reference Figure 3-6 The outer peripheral surface of the connector body 4 is provided with a connector protrusion 45 corresponding to the position of the slot 43. The upper part of the connector body 4 can be connected to pipe structures such as faucets through the threaded structure of the connecting cylinder 5. During installation or disassembly, the connector body 4 needs to be rotated. The setting of the connector protrusion 45 can increase the contact area of ​​the user's hand and facilitate the application of force. Since the setting of the slot 43 and the first groove 44 will reduce the thickness of the side wall of the connector body 4, setting the connector protrusion 45 to correspond to the slot 43 can increase the wall thickness and improve the stability and life of the product.

[0041] Reference Figure 3 The thread structure is an internal thread, and the outer peripheral surface of the elastic seal 6 is provided with several elastic bosses 61 that can be engaged with the internal thread of the connecting cylinder 5. The connecting cylinder 5 adopts an internal thread connection. During installation, the pipe inserted above the connecting cylinder 5 will press against the elastic seal 6, thereby achieving a sealing effect. The setting of the elastic bosses 61 allows the elastic seal 6 to be engaged with the internal thread, and because it is elastic, a larger force can be used to install or remove the elastic seal 6.

[0042] Reference Figure 3 The outer peripheral surface of the elastic seal 6 is provided with several first planes, and the elastic bosses 61 are connected to the first planes one by one. Since the elastic bosses 61 are engaged with the internal thread, it is easier to remove the elastic seal 6 by holding it at the position corresponding to the elastic bosses 61. In order to ensure sealing and stability, the outer diameter of the elastic seal 6 is slightly smaller than the inner diameter of the internal thread. Therefore, connecting the elastic bosses 61 to the first plane makes it easy to observe which direction the elastic bosses 61 are located, and makes it easy to remove.

[0043] Reference Figure 3The valve body 2 is also provided with a second protrusion 22 at one end near the connector body 4. The first buckle 42 is engaged between the first protrusion 21 and the second protrusion 22. The second protrusion 22 can provide a limiting function, and a double buckle structure can be set as needed to engage with the first protrusion 21 and the second protrusion 22 respectively, further improving the stability of the fit.

[0044] Reference Figure 2 and Figure 6 The valve body 2 has a mounting boss 23 and a mounting through hole 25 on its inner side wall. The switch assembly 3 includes a valve core 31 disposed in the valve body 2 and a valve handle 32 inserted into the mounting through hole 25 and detachably connected to the valve core 31. The valve core 31 abuts against the mounting boss 23. The water passage 1 can be opened or closed by rotating the valve handle 32. The valve core 31 is a ball valve and is detachably connected to the valve body 2. Existing switch assemblies 3 all have bosses on both the upper and lower sides of the valve core 31 for snap-fit. This application only has a mounting boss 23 on one side of the valve core 31 to achieve detachable installation of the valve core 31 and improve product compatibility.

[0045] pass Figure 2 It can be seen that the upper and lower positions on the left side of the valve core 31 are curved so that the valve core 31 can rotate and move a certain distance in the water passage 1, and the circumferential surface on the right side is provided with several steps so that the valve core 31 can move and rotate a certain distance in the installation through hole 25, thereby allowing the valve core 31 of this application to enter or exit from the water passage 1.

[0046] Reference Figure 2 and Figure 3 and Figure 6 The outer peripheral surface of the valve body 2 is provided with an annular groove 24, and the valve handle 32 is provided with a valve handle protrusion 321 inserted into the annular groove 24. The valve handle protrusion 321 is inserted into the annular groove 24, which can provide positioning and limiting functions, and prevent the valve handle 32 from rotating too much or too little, resulting in the failure to open or close the water passage 1 smoothly.

[0047] Reference Figure 2 and Figure 4 and Figure 5 The inner wall of the first groove 44 is provided with a guide slope 441; the guide slope 441 provides a guiding function and increases the thickness of the inner wall of the slot 43, thereby improving the stability of the connection; the guide slope 441 makes the inner diameter of the first groove 44 smaller and smaller, thereby increasing the depth difference between the slot 43 and the first groove 44, making it more difficult for the first buckle 42 to come out.
