Description

Technical Field

[0001] The utility model belongs to the technical field of water replenishing and salt absorbing valves, and particularly relates to a valve body integrating water replenishing and salt absorbing. Background Art

[0002] The water replenishing and salt absorbing valve mainly has two functions in a water softener:

[0003] One is the water replenishing function. Generally, the multi-way control valve on the water softener controls the water replenishing capacity by controlling the water replenishing time and water replenishing flow rate. The water replenishing volume each time is roughly the same. Water flows into the salt tank from the water delivery hose. However, when the control valve malfunctions or is damaged, there may be a situation of excessive water replenishment. When the water replenishing volume exceeds the volume of the salt tank, it is easy to cause water overflow, affecting the normal operation of the equipment. The other is the salt absorbing function. After the multi-way control valve sets the salt absorbing time to start, the water in the salt tank flows back and is sucked into the control valve from the water delivery hose, and then flows into the resin tank through the control valve to achieve the salt absorbing effect. However, in the existing structure, the reflux structure is relatively complex and the salt absorbing efficiency is low. Therefore, the utility model proposes a new solution for the above technical problems. Summary of the Utility Model

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 5 shown, an embodiment of the present invention provides a valve body that combines water replenishment and salt absorption, including:

[0029] The valve body 1, the valve body 1 is provided with a water outlet 111; a support frame, the support frame is connected to the valve body 1; a control structure, the control structure includes a floating structure and an adjustment structure, the adjustment structure is used to block the water outlet 111 on the valve body 1, one end of the floating structure is connected to the adjustment structure, and the other end is connected to the support frame, and the floating structure drives the adjustment structure to move by following the liquid level displacement, so as to realize the sealing or detachment of the adjustment structure from the water outlet 111, so that the raw water in the water replenishment process flows out through the water outlet or the brine in the salt absorption process flows back through the water outlet, so as to accurately control the water storage volume in the valve body.

[0030] Furthermore, the adjusting structure is provided with a swing assembly and a valve core assembly 322. The valve core assembly 322 is connected to the valve body 1. The swing assembly is swingably connected to one side of the valve core assembly 322 relative to the valve body 1. One end of the swing assembly is connected to the floating structure, and the other end is connected to the valve core assembly 322. The valve core assembly 322 approaches the water outlet 111 as the floating structure rises through the swing assembly, and moves away from the water outlet 111 as the floating structure descends, so that the valve core assembly 322 adjusts the water replenishment amount by sealing or disengaging from the water outlet 111, thereby improving the convenience of adjustment; the swing assembly adopts a limit design, and the maximum swing angle is used to abut against the valve body 1 to limit the maximum downward swing angle or the maximum upward swing angle of the swing assembly, avoiding the valve core assembly 322 from excessively penetrating or completely disengaging from the water outlet 111, thereby preventing the adjustment of the water replenishment amount from exceeding the preset range and improving the stability of adjustment.

[0031] Still further, the swing assembly is provided with a pin 3211 and a swing link 3212. The swing link 3212 is connected to one side of the valve body 1. One end of the swing link 3212 is connected to the valve core assembly 322, and the other end is hinged to one end of the pin 3211; the other end of the pin 3211 is connected to the floating structure. Through the upward or downward movement of the floating structure, the swing link 3212 is driven to swing downward or upward, so as to drive the valve core assembly 322 to penetrate or disengage from the water outlet 111 to adjust the water replenishment amount. And the left and right sides of the swing link 3212 can respectively abut against the valve body 1 to limit the angle of the swing link 3212, avoiding the valve core assembly 322 from excessively penetrating or completely disengaging from the water outlet 111, thereby preventing the adjustment of the water replenishment amount from exceeding the preset range and improving the stability of adjustment; the swing link 3212 is made of high-strength and wear-resistant materials to improve its service life during frequent swinging and maintain the adjustment accuracy between the valve core assembly 322 and the water outlet 111; the surface of the swing link 3212 is also provided with a corrosion-resistant coating to enhance its durability and stability in a humid environment or under different water quality conditions; the pin 3211 is designed with a quick-release structure, one end can be connected to the floating structure, and the other end can limit the longitudinal or lateral offset of the swing link 3212, enabling the user to conveniently disassemble or replace the pin 3211 for easy maintenance or adjustment according to actual needs; the connection mode between the pin 3211 and the swing link 3212 can also adopt a double-directional hinge structure, enabling the swing link 3212 to swing freely in the directions perpendicular and parallel to the valve body 1, thereby providing a more flexible and precise sealing adjustment.

[0032] Furthermore, the swing link 3212 is provided with a fixing hole 32121, a spool connection hole 32122, and a pin connection hole 32123. The swing link 3212 is swingably connected to one side of the valve body 1 through the fixing hole 32121. The swing link 3212 is connected to the spool assembly 322 through the spool connection hole 32122, and the spool connection hole 32122 is designed as an ellipse. The elliptical design can better distribute stress, reduce the concentrated stress at the connection point, thereby reducing the risk of fracture or damage of the swing link 3212 and reducing wear caused by friction, so as to extend the service life of the swing link 3212. The pin 3211 is hinged to the swing link 3212 through the pin connection hole 32123, and the diameter of the abutting end of the pin 3211 and the pin connection hole 32123 is greater than the diameter of the pin connection hole 32123 to prevent the swing link 3212 from longitudinally or laterally shifting and improve the stability of the connection.

[0033] Further, the spool assembly 322 is provided with a spool body 3221 and a spool seal ring 3222. The spool body 3221 is provided with a spool upper connection end 32211 and a spool lower connection end 32212. The spool lower connection end 32212 is designed as a stepped shaft rotary body to better seal the water outlet 111 and enhance the sealing performance of the spool body 3221. The spool upper connection end 32211 is provided with a spool connection shaft, and the spool connection shaft can be connected in the spool connection hole 32122 so that the swing link 3212 can drive the spool body 3221 to seal or disengage from the water outlet 111 to adjust the makeup water volume. The spool seal ring 3222 is detachably connected to the spool lower connection end 32212. The detachable connection facilitates timely replacement of the spool seal ring 3222 to ensure that the sealing effect of the spool lower connection end 32212 on the water outlet 111 during use is stable and reliable.

[0034] Furthermore, the spool seal ring 3222 is a V-shaped seal ring. The opening direction of the V-shaped seal ring is towards the inflow direction of the water flow to enhance the sealing effect by using water pressure. When the water flow passes through, the edge of the V-shaped seal ring will more closely fit the contact surface between the spool lower connection end 32212 and the water outlet 111. The V-shaped seal ring 3222 is made of a composite material. The inner layer is an elastic rubber material to adapt to different water pressure changes, and the outer layer is a wear-resistant material to improve the durability and corrosion resistance of the seal ring. The outer edge of the V-shaped seal ring is provided with a guiding protrusion for accurately positioning the V-shaped seal ring during installation to ensure that when the spool assembly 322 is inserted into the water outlet 111, the V-shaped seal ring can closely fit the inner wall of the water outlet 111 and improve the tightness of the seal.

[0035] Furthermore, the floating structure is provided with a floating body 311 and a nylon line 312. The floating structure is designed in a conical shape, with the cross-sectional area of the upper end smaller than that of the lower end. The larger area at the lower end can increase the displacement of the floating body 311, thereby providing greater buoyancy; the smaller area at the upper end can reduce the water flow, making the floating body 311 more stable on the water surface, so that the floating body 311 can maintain good buoyancy and stability in waters of different depths, and at the same time it is convenient to connect the upper end to other devices or ropes; upper and lower limit posts are also provided on the nylon line 312. One end of the nylon line 312 is connected to the support frame, and the other end is connected to the pin 3211. The floating body 311 is fixed between the upper and lower limit posts of the nylon line 312, so that the floating body 311 drives the nylon line 312 to move upward by buoyancy, and the nylon line 312 drives the swing link 3212 to swing downward to seal the water outlet 111. Preferably, at this time, the pressure exerted by the valve core seal ring 3222 on the valve core body 3221 on the water outlet 111 is more than twice that of the entire floating body 311, and the sealing strength is greater to enhance the sealing performance of the valve core assembly 322; the floating body 311 is made of high-density waterproof material to enhance the stability of its buoyancy in water and prevent water absorption or deformation of the material caused by long-term use of the floating body 311, and extend the service life of the floating body 311.

[0036] Furthermore, the support frame is provided with an upper positioning sleeve 21 and a vertical water pipe 22. The upper positioning sleeve 21 is provided with a nylon line hole 211, a vertical water pipe hole 212, and a drainage groove 213. The drainage groove 213 allows water flow to pass through quickly, so that the buoyancy can be reduced when the upper positioning sleeve 21 is submerged in water, and the stability of the upper positioning sleeve 21 is enhanced; a pipe seal ring is provided in the vertical water pipe hole 212. The vertical water pipe 22 is connected to the valve body 1. The upper positioning sleeve 21 is connected to the vertical water pipe 22 through the vertical water pipe hole 212 and fastened through the pipe seal ring, so that the nylon line 312 can be stably connected to the nylon line hole 211 of the upper positioning sleeve 21; the vertical water pipe 22 is also provided with a 90° elbow 221, which can provide precise flow direction control to ensure that the fluid flows along a predetermined path. At the same time, when the pipeline needs to be maintained or replaced, the 90° elbow 221 is easy to disassemble and replace; the support frame is also provided with a fixed buckle 23. In the embodiment of the present invention, preferably, there are two fixed buckles 23. The fixed buckle 23 is provided with a fixed buckle opening 231 and a fixed buckle seat 232. The fixed buckle opening 231 is connected to the fixed buckle seat 232, and the fixed buckle opening 231 can be snapped into the vertical water pipe 22; the fixed buckle seat 232 is provided with a connection fastening hole, and a fastener can be used to fix the fixed buckle 23 on the inner wall of the salt barrel through the connection fastening hole to enhance the structural stability of the support frame.

[0037] Furthermore, the valve body 1 is provided with a valve body base 11 and side support arms 12. The water outlet 111 is arranged on the valve body base 11. The side support arms 12 are integrally formed with the valve body base 11, and the side support arms 12 are provided with a rotating shaft 121. A threaded structure is provided on the rotating shaft 121, so that the swing link 3212 can be fastened to the rotating shaft 121 to prevent the swing link 3212 from disengaging from the rotating shaft 121 during the swinging process, enhancing the stability of the structure. The structure of the side support arms 12 can be designed to be hollow to reduce the weight of the entire valve body 1, and at the same time, it has sufficient strength and rigidity, facilitating installation and maintenance.

[0038] Further, the valve body base 11 is also provided with a vertical pipe opening 112 and a quick-release buckle 113. The quick-release buckle 113 is fixedly connected to the outer end of the vertical pipe opening 112 for the vertical water pipe 22 to be inserted and fastened. The quick-release buckle 113 adopts a double-buckle structure design to increase the stability of the vertical water pipe 22 after being fixed, so as to prevent the vertical water pipe 22 from loosening or disengaging under high water pressure conditions. The surface of the quick-release buckle 113 is also provided with an anti-slip structure to increase the friction during operation, ensuring that the vertical water pipe 22 can be quickly and firmly installed or disassembled even in a humid environment. The inner wall of the vertical pipe opening 112 is provided with a sealing ring to provide an additional sealing effect when the vertical water pipe 22 is inserted, so as to prevent water from leaking from the connection between the vertical pipe opening 112 and the vertical water pipe 22, enhancing the sealing performance of the structure.

[0039] The working principle of the present utility model is as follows:

[0040] Under normal circumstances, when the control valve is opened to suck salt, since the valve core assembly 322 does not play a sealing role at this time, that is, the water level has not reached the upper limit of the water level set by the floating body 311, the brine can flow through the gap between the valve core assembly 322 and the water outlet 111, then reach the control valve through the vertical water pipe 22, and finally flow into the resin tank through the control valve, completing the entire salt suction process.

[0041] When the salt absorption process set by the control valve ends, the control valve opens the water replenishment process; raw water passes through the control valve and flows into the valve body 1 through the vertical water pipe 22. At this time, the valve core assembly 322 is still in the open state due to the gravity of the floating body 311. The raw water flows into the salt bucket through the gap between the valve core assembly 322 and the water outlet 111. As the water volume increases, under the action of buoyancy, the floating body 311 slowly rises. At this time, the upper limit post and the lower limit post fix the floating body 311 and are connected to the nylon rope 312; as the water level rises, the nylon rope 312 drives the swing link 3212 through the pin 3211, causing the valve core assembly 322 to descend, and the gap between it and the water outlet 111 becomes smaller and smaller until the valve core seal ring 3222 on the valve core assembly 322 completely blocks the gap with the water outlet 111. And the valve core seal ring 3222 is a V-shaped seal ring. At this time, the pressure exerted by the V-shaped seal ring on the water outlet 111 is more than twice the buoyancy of the entire floating body 311, and the sealing strength is greater, and the entire water replenishment process is completed.

[0042] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information. Similarly, "second" information can also be called "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0043] The above is the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and deformations can be made, and these improvements and deformations are also regarded as the protection scope of the present invention.
