Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic water valve equipment technology, and in particular to a hexagonal pressure water valve with adjustable water flow rate. Background Technology
[0002] Pneumatic valves are valves driven by compressed air. They are convenient and safe to use, and can be controlled locally or remotely. They can control a single valve or centrally control multiple valves. When combined with a computer, they can achieve programmed control. Pneumatic valves are used in various fields such as chemical, papermaking, food, pharmaceutical, drainage, and gas industries, especially in the field of water circuit automation. Existing pneumatic water valves control the opening and closing of water flow by blowing air into the cavity to squeeze a piston. Opening the water flow requires overcoming the water pressure at the inlet end of the piston, requiring more air pressure to squeeze and push the piston. This results in poor sensitivity and cumbersome operation. Utility Model Content
[0003] In order to overcome the technical defects mentioned in the background art, the purpose of this utility model is to provide a hexagonal pressure valve with adjustable water flow rate.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A hexagonal pressure valve with adjustable water flow rate includes an air inlet base, a valve seat connected to one end of the air inlet base, and a valve core. A diaphragm is disposed between the air inlet base and the valve seat. An annular air inlet channel is disposed inside the air inlet base, with the end of the air inlet channel facing the diaphragm open. An air inlet connector communicating with the air inlet channel is disposed on one side of the air inlet base. The valve seat has a first cavity, a second cavity, and a water inlet channel communicating between the first cavity and the second cavity, all open at the end facing the diaphragm. One end of the valve core is disposed in the first cavity and in contact with the diaphragm, and the other end of the valve core passes through the water inlet channel and is located in the second cavity. The other end of the valve core is used to close or open the water inlet channel. The valve seat has an outlet connector communicating with the first cavity and an inlet connector communicating with the second cavity.
[0006] By adopting the above technical solution, an annular air intake channel is set on the air intake base. After gas is blown into the air intake channel through the air intake connector, the gas circulates once along the air intake channel to increase the gas pressure, and then is pressed down onto the diaphragm. The diaphragm deforms and squeezes the valve core to move towards the second chamber. The other end of the valve core opens the water inlet channel, and water flows sequentially from the water inlet connector, the second chamber, the water inlet channel, and the first chamber into the water outlet connector. The annular air intake channel can increase the air pressure, thus more easily pushing the valve core to counteract the effect of water pressure. The water inlet channel opens more easily and quickly, with high sensitivity and convenient use. Moreover, the diaphragm response is more sensitive, with better deformation and reset effects, and a longer service life.
[0007] Furthermore, the diameter of the air intake channel is largest at the end closest to the diaphragm, increasing the blowing area of the diaphragm and thus causing the diaphragm to squeeze the valve core more quickly.
[0008] Furthermore, the air intake channel includes an annular air intake section and a trumpet-shaped pressurizing section. The diameter of the air intake section is smaller than the diameter of the pressurizing section, and the diameter of the pressurizing section increases gradually along the direction close to the diaphragm. The annular design of the air intake section increases the pressure of the blown-in gas, which, when applied to the diaphragm through the trumpet-shaped pressurizing section, provides even greater pressure, resulting in higher efficiency and a more sensitive response in pushing the valve core to open the water inlet channel.
[0009] Furthermore, the end face area of the pressurizing part away from the air intake part is larger than the end face area of the valve core, ensuring the pressure-bearing area of the valve core and improving the opening efficiency.
[0010] Furthermore, the valve core includes a pressure-bearing part, a sealing part, a connecting rod connecting the pressure-bearing part and the sealing part, and a return spring fitted on the connecting rod. The pressure-bearing part is configured as a circular plate structure, with one side of the pressure-bearing part in contact with the diaphragm. One end of the return spring abuts against the other side of the pressure-bearing part, and the other end of the return spring abuts against the side wall of the first cavity. When air blowing stops, the return spring allows the pressure-bearing part to automatically return to its original position, while simultaneously allowing the sealing part to seal the water inlet channel, providing automatic sealing and greater convenience. One end of the sealing part is located inside the water inlet channel, and the other end is located inside the second cavity. The other end of the sealing part has a protruding first sealing ring to seal the water inlet channel, making opening and sealing more convenient and quick.
[0011] Furthermore, one end of the sealing part is configured as a frustum-shaped structure with the smallest diameter at the end. The amount of water entering the water can be controlled by adjusting the depth of the sealing part in the water inlet channel, resulting in higher compatibility.
[0012] Furthermore, the hexagonal water valve with adjustable water flow also includes a valve stem that is movably connected to the valve seat. The valve seat has an adjustment channel communicating with the second cavity. One end of the valve stem is movably positioned along the length of the adjustment channel, and the outlet connector is connected to the end of the adjustment channel furthest from the second cavity. The water inlet flow can be adjusted via the valve stem, saving water, being convenient to use, and having high compatibility.
[0013] Furthermore, one end of the valve stem located within the regulating channel is designed with a conical structure, facilitating adjustment of different water flow rates, providing stepped control, making operation more convenient, and ensuring high control precision. The other end of the valve stem is threadedly connected to the valve seat and sealed by a second sealing ring. The water flow rate is adjusted by screwing the valve stem in and out, making adjustment convenient.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] This invention features an annular air intake channel on the air intake base. Gas is blown into the air intake channel through the air intake connector, circulating once to increase the gas pressure. This pressure is then applied to the diaphragm, causing it to deform and compress the valve core, moving it towards the second chamber. The other end of the valve core opens the water inlet channel, allowing water to flow sequentially from the water inlet connector, second chamber, water inlet channel, and first chamber into the water outlet connector. The annular air intake channel increases the air pressure, making it easier to push the valve core to counteract the water pressure. The water inlet channel opens more easily and quickly, exhibiting high sensitivity and ease of use. Furthermore, the diaphragm response is more sensitive, with better deformation and reset effects, resulting in a longer service life. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 The embodiments of this utility model will be described in further detail below.
[0023] A hexagonal water valve 1 with adjustable water flow rate, such as Figure 1 As shown, it includes an air intake base 2, a valve seat 3 connected to one end of the air intake base 2, and a valve core. A diaphragm 6 is disposed between the air intake base 2 and the valve seat 3. An annular air intake channel 21 is disposed inside the air intake base 2, with the end of the air intake channel 21 open facing the diaphragm 6. An air intake connector 7 communicating with the air intake channel 21 is disposed on one side of the air intake base 2. A first cavity 31, a second cavity 32, and a water inlet channel communicating between the first cavity 31 and the second cavity 32 are disposed inside the valve seat 3. One end of the valve core is disposed inside the first cavity 31 and in contact with the diaphragm 6, and the other end of the valve core passes through the water inlet channel and is located inside the second cavity 32. The other end of the valve core is used to close or open the water inlet channel. A water outlet connector 8 communicating with the first cavity 31 and a water inlet connector 9 communicating with the second cavity 32 are disposed on the valve seat 3.
[0024] The first chamber 31, the water inlet channel, and the second chamber 32 are sequentially connected along the central axis of the valve seat 3. An annular air inlet channel 21 is provided on the air inlet base 2. After gas is blown into the air inlet channel 21 through the air inlet connector 7, the gas circulates once along the air inlet channel 21 to increase the gas pressure, and then presses down onto the diaphragm 6. The diaphragm 6 deforms and squeezes the valve core towards the second chamber 32. The other end of the valve core opens the water inlet channel, and water flows sequentially from the water inlet connector 9, the second chamber 32, the water inlet channel, and the first chamber 31 into the water outlet connector 8. The annular air inlet channel 21 increases the air pressure, thus more easily pushing the valve core to counteract the influence of the water pressure in the second chamber 32. The water inlet channel opens more easily and quickly, with high sensitivity and ease of use. Moreover, the diaphragm 6 is more responsive, with better deformation and reset effects, and a longer service life. The air inlet base 2, diaphragm 6, and valve seat 3 can be connected and fixed with bolts.
[0025] In some embodiments, the diameter of the air intake channel 21 is largest at the end closest to the diaphragm 6, increasing the blowing area of the diaphragm 6, thereby causing the diaphragm 6 to squeeze the valve core more quickly.
[0026] Preferably, to improve the ramming performance of the gas, the air intake channel 21 includes an annular air intake portion 211 and a trumpet-shaped pressurizing portion 212. The diameter of the air intake portion 211 is smaller than the diameter of the pressurizing portion 212, and the diameter of the pressurizing portion 212 increases gradually along the direction close to the diaphragm 6. The annular air intake portion 211 increases the pressure of the blown gas by changing the gas flow direction. Then, the trumpet-shaped pressurizing portion 212 acts on the diaphragm 6, providing greater pressure and stronger impact force, resulting in higher efficiency and more sensitive response in pushing the valve core to open the water inlet channel.
[0027] In this design, the end face area of the pressurizing part 212 away from the air intake part 211 is larger than the end face area of the valve core, ensuring the pressure-bearing area of the valve core and improving the opening efficiency.
[0028] In some embodiments, the valve core includes a pressure-bearing portion 41, a sealing portion 42, a connecting rod 43 connecting the pressure-bearing portion 41 and the sealing portion 42, and a return spring 44 fitted onto the connecting rod 43. The pressure-bearing portion 41 is configured as a circular plate structure, with one side of the pressure-bearing portion 41 in contact with the diaphragm 6. One end of the return spring 44 abuts against the other side of the pressure-bearing portion 41, and the other end of the return spring 44 abuts against the side wall of the first cavity 31. When blowing stops, the return spring 44 allows the pressure-bearing portion 41 to automatically return to its original position, while simultaneously allowing the sealing portion 42 to seal the water inlet channel, achieving automatic sealing and making it more convenient to use. One end of the sealing portion 42 is disposed within the water inlet channel, and the other end of the sealing portion 42 is disposed within the second cavity 32. The other end of the sealing portion 42 is provided with a protruding first sealing ring 45 to seal the water inlet channel, making opening and sealing more convenient and quick.
[0029] Preferably, one end of the sealing part 42 is configured as a frustum-shaped structure, and the diameter of the end is the smallest. The amount of water entering the water can be controlled and adjusted by controlling the depth of the sealing part 42 in the water inlet channel, which has higher compatibility.
[0030] In some embodiments, the hexagonal water valve 1 with adjustable water flow rate further includes a valve stem 5 that is movably connected to the valve seat 3. The valve seat 3 is provided with an adjustment channel 33 communicating with the second cavity 32. One end of the valve stem 5 is movably disposed along the length direction of the adjustment channel 33, and the water outlet connector 8 is connected to the end of the adjustment channel 33 away from the second cavity 32. The water inlet flow rate of the inlet valve stem 5 can be adjusted by the valve stem 5, which saves water, is convenient to use, and has high compatibility.
[0031] Preferably, one end of the valve stem 5 located within the regulating channel 33 is designed with a conical structure, facilitating the adjustment of different water flow rates, providing stepped control, making operation more convenient, and ensuring high control precision. The other end of the valve stem 5 is threadedly connected to the valve seat 3 and sealed by a second sealing ring 51. The water flow rate is adjusted by screwing the valve stem 5 in and out, making adjustment convenient. Specifically, a nut 34 can be provided at the end of the valve seat 3, and the other end of the valve stem 5 can be provided with an external thread. The valve stem 5 and the nut 34 are threaded together, making installation easier and reducing costs.
[0032] In actual use, when it is necessary to open the water inlet channel, gas is blown into the air inlet channel 21 from one end of the air inlet connector 7. The air inlet channel 21 circulates and pressurizes, changing the direction of the gas flow. This causes the pressurized gas to press down on the diaphragm 6, which deforms and pushes the valve core toward the second cavity 32. The first sealing ring 45 separates from the end of the water inlet channel, and the water inlet channel opens. The water flow delivered by the water inlet connector 9 is delivered from the regulating channel 33, the second cavity 32, the water inlet channel, and the first cavity 31 to the water outlet connector 8. The depth of the valve stem 5 in the regulating channel 33 can be adjusted by turning it in or out, thereby controlling the flow rate of water flowing out of the water inlet connector 9.
[0033] When it is necessary to shut off the water flow, the air inlet connector 7 stops inflating, the air pressure in the air inlet channel 21 decreases, the diaphragm 6 automatically resets, the valve core moves toward the first cavity 31 under the elastic restoring force of the return spring 44, the pressure bearing part 41 returns to its initial position under the elastic force of the return spring 44, and the first sealing ring 45 abuts against and seals the end of the water inlet channel, blocking the water flow from the second cavity 32 into the water inlet channel.
[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
