Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water inlet valves, and particularly relates to a single float water inlet valve. Background Art
[0002] When the current single float water inlet valve encounters low water pressure, when water flows into the water tank, the water surface is stable. As the water level line rises steadily, the single float also rises steadily until the single float closes the valve; when encountering high water pressure, water flows into the water tank quickly, causing the water surface to be unstable. Since the single float is relatively light, it is easily affected by the water surface, resulting in premature water shut-off. Compared with the water inlet under low water pressure, the position of the highest water level line during high water pressure water inlet is lower. Therefore, the problem of the existing single float water inlet valve is that the single float is easily affected by different high and low water pressures, and when encountering different high and low water pressures, it will cause the water level in the water tank to be unstable. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a single float water inlet valve, which overcomes the above defects, reduces the influence of different high and low water pressures on the single float, so as to avoid the instability of the water level in the water tank when the single float encounters different high and low water pressures.
[0004] To achieve the above purpose, the solution of the utility model is as follows:
[0005] A single float water inlet valve is arranged in a water tank. The water inlet valve has a water inlet channel and a water outlet channel. The water inlet channel and the water outlet channel are conducted or blocked by a valve. The single float slides up and down to control the conduction or blockage of the water inlet channel and the water outlet channel. It has a groove that can be filled with water, and at least one buoyancy chamber; a diversion component is arranged in the water outlet channel of the water inlet valve. The diversion component is provided with a water receiving cavity for receiving water from the water outlet channel. A water outlet hole is arranged at the bottom of the water receiving cavity. A water guiding plate covering the water outlet hole is arranged above the water outlet hole. The water guiding plate is used to divert the water entering the water receiving cavity between the water guiding plate and the side wall of the water receiving cavity. There is a water passing gap between the water guiding plate and the water outlet hole, so that the water flow passes through the water passing gap and the water outlet hole in sequence and flows into the water tank. A diversion channel is opened on the side wall of the water receiving cavity. The diversion channel is used to lead out part of the water flow in the water receiving cavity and fall into the groove to provide additional counterweight for the single float.
[0006] Further, on the bottom of the cavity of the water receiving cavity, a drainage groove is recessed around the water outlet hole for the water flow between the water guiding plate and the side wall of the water receiving cavity to flow into, and the drainage groove is communicated with the diversion channel.
[0007] Further, the area of the water outlet hole is larger than the sum of the areas of all the water passing gaps.
[0008] Further, a drain hole is also provided at the bottom of the groove to drain the water in the groove into the water tank.
[0009] Further, the top of the water guide piece is conical.
[0010] Further, it further includes a water receiving component. The water receiving component includes a water outlet pipe and a water receiving groove. The guiding component is arranged at the water outlet end of the water outlet channel. The water receiving groove is sleeved on the outer periphery of the guiding component and the water outlet channel. The water outlet pipe is arranged on the water receiving groove below the guiding component, so that the water flowing out of the water outlet hole enters the water outlet pipe and then flows into the water tank from the water outlet pipe.
[0011] Further, on the outer side wall of the water receiving cavity, a water passing cavity covering the guiding channel is arranged at the guiding channel, so that the water flowing out of the guiding channel enters the water passing cavity. The water passing cavity has a downward opening for the water in the water passing cavity to flow out.
[0012] Further, an additional water discharging part is arranged at the bottom of the water receiving groove. The additional water discharging part is located directly above the groove. The side wall of the water passing cavity far from the water receiving cavity is located at the water inlet end of the additional water discharging part, and this side wall extends downward into the additional water discharging part to divide the additional water discharging part into two parts. One part of the additional water discharging part is communicated with the water passing cavity through the opening to inject the water in the water passing cavity into the groove.
[0013] Further, the valve is a back pressure valve which has a pressure relief through hole located above the water receiving groove, so that the water flowing out of the pressure relief through hole flows into the water receiving groove and is injected into the groove through the other part of the additional water discharging part.
[0014] Further, the water inlet valve includes a valve seat, and the valve is detachably arranged in the valve seat.
[0015] After adopting the above scheme, the beneficial effects of the utility model are as follows:
[0016] In the utility model, a water guide piece covering the water outlet hole is arranged above the water outlet hole. The water guide piece guides the water between the water guide piece and the side wall of the water receiving cavity. The water flow passes through the water passing gap and the water outlet hole in sequence and then enters the water tank. Moreover, the water receiving cavity also has a guiding channel which guides out part of the water in the water receiving cavity and injects it into the groove of the single floating bucket to increase the counterweight of the single floating bucket. Therefore, in the utility model, whether in a low water pressure environment or a high water pressure environment, part of the water flow flows out of the guiding channel and is injected into the groove of the single floating bucket to increase the counterweight of the single floating bucket, so as to reduce the influence of different high and low water pressures on the single floating bucket and avoid the instability of the water level in the water tank when the single floating bucket encounters different high and low water pressures.

Detailed implementation manners
[0023] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.
[0024] As Figures 1 to 5 shown, the present utility model provides a single floating bucket 15 water inlet valve 10, which is arranged in a water tank. The water inlet valve 10 has a water inlet channel 11 and a water outlet channel 12. A valve 13 is used to conduct or cut off between the water inlet channel 11 and the water outlet channel 12. The single floating bucket 15 slides up and down to control the valve 13 to conduct or cut off the water inlet channel 11 and the water outlet channel 12. It has a groove 151 that can be filled with water, and at least one buoyancy chamber 152;
[0025] A flow guiding component 16 is arranged in the water outlet channel 12 of the water inlet valve 10. The flow guiding component 16 is provided with a water receiving chamber 161 for receiving water from the water outlet channel 12. A water outlet hole 162 is arranged at the bottom of the water receiving chamber 161. A water guiding piece 163 covering the water outlet hole 162 is arranged above the water outlet hole 162. The water guiding piece 163 is used to guide the water entering the water receiving chamber 161 between the water guiding piece 163 and the side wall of the water receiving chamber 161. A water passing gap 164 is formed between the water guiding piece 163 and the water outlet hole 162, so that the water flow passes through the water passing gap 164 and the water outlet hole 162 in sequence and flows into the water tank. A flow guiding channel 165 is formed on the side wall of the water receiving chamber 161. The flow guiding channel 165 is used to guide part of the water flow in the water receiving chamber 161 out of the water receiving chamber 161 and fall into the groove 151 to provide additional counterweight for the single floating bucket 15;
[0026] No matter in a low water pressure environment or a high water pressure environment, the utility model has part of the water flow guided out from the guide channel 165 and falls into the groove 151 of the single float 15, thereby increasing the counterweight of the single float 15 and reducing the influence of different water pressures on the single float 15, so as to avoid the unstable water level in the water tank when the single float 15 encounters high or low water pressures. In addition, the utility model can also buffer the water pressure and reduce the impact force of the water flow through the water guide sheet 163.
[0027] Specifically, the buoyancy chamber 152 is designed to be open downward and airtight upward, so that air is sealed into the buoyancy chamber 152 when injected, so that the single float barrel 15 floats. It can be understood that when the groove 151 is fully injected, the single float barrel 15 has a buoyancy that is well coordinated with the valve 13;
[0028] When the valve 13 is opened, the water inlet channel 11 and the water outlet channel 12 are connected. At this time, water is output not only from the water outlet hole 162, but also from the diversion channel 165. The water output from the diversion channel 165 is injected into the groove 151 to increase the counterweight for the single float 15, and a drainage hole is also provided at the bottom of the groove 151 so that the water in the groove 151 can be discharged from the drainage hole into the water tank. It can be understood that since the efficiency of injecting water into the groove 151 is greater than the efficiency of draining water, the groove 151 can be filled with water while draining water and injecting water, and the water outlet end of the drainage hole is always above the water surface.
[0029] Furthermore, the area of the water outlet hole 162 is larger than the sum of the areas of all the water gaps 164 , so as to increase the efficiency of water flowing out of the water receiving cavity 161 .
[0030] Furthermore, the top of the water guide piece 163 is conical, so as to facilitate the water flow entering the water receiving cavity 161 and to facilitate buffering the water pressure and reducing the impact force of the water flow.
[0031] Furthermore, a drainage groove 166 is concavely provided around the water outlet hole 162 at the bottom of the water receiving chamber 161. The drainage groove 166 is used for the water flow between the water guide sheet 163 and the side wall of the water receiving chamber 161 to flow in, and the drainage groove 166 is connected to the guide channel 165. When the water flow between the water guide sheet 163 and the side wall of the water receiving chamber 161 flows into the drainage groove 166, and when the drainage groove 166 is not full, the water in the drainage groove 166 will first flow out from the guide channel 165, but due to the water receiving chamber 161, the water in the drainage groove 166 will flow out from the guide channel 165. The water intake efficiency of the water cavity 161 is much greater than the water outflow efficiency of the diversion channel 165. Therefore, when water flows outward from the diversion channel 165, the water level in the drainage groove 166 will gradually increase until it overflows the drainage groove 166, passes through the water gap 164 and the water outlet hole 162 in turn, and flows into the water tank from the water outlet hole 162. Therefore, the drainage groove 166 can cooperate with the diversion channel 165 to divert water, and can also further buffer the water flow, reduce the water pressure and the impact force of the water flow.
[0032] Furthermore, the utility model further includes a water receiving component 17, which includes a water outlet pipe 171 and a water receiving tank 172. The guiding component 16 is arranged at the water outlet end of the water outlet channel 12. The water receiving tank 172 is sleeved on the outer periphery of the guiding component 16 and the water outlet channel 12. The water outlet pipe 171 is arranged on the water receiving tank 172 below the guiding component 16, so that the water flowing out from the water outlet hole 162 enters the water outlet pipe 171 and then flows into the water tank from the water outlet pipe 171. In this embodiment, the guiding component 16 is located above the groove 151;
[0033] Furthermore, on the outer side wall of the water receiving cavity 161, at the position of the guiding channel 165, a water passing cavity 167 covering the guiding channel 165 is arranged, so that the water flowing out from the guiding channel 165 enters the water passing cavity 167. The water passing cavity 167 has a downward opening for the water in the water passing cavity 167 to flow out;
[0034] Specifically, an additional water discharging part 1721 is arranged at the bottom of the water receiving tank 172. The additional water discharging part 1721 is located directly above the groove 151. The side wall of the water passing cavity 167 far from the water receiving cavity 161 is located at the water inlet end of the additional water discharging part 1721, and this side wall extends downward into the additional water discharging part 1721 to divide the additional water discharging part 1721 into two parts. One part of the additional water discharging part 1721 is communicated with the water passing cavity 167 through the opening to inject the water in the water passing cavity 167 into the groove 151; specifically, the water outlet end of the additional water discharging part 1721 points to the groove 151 to guide the water into the groove 151;
[0035] Furthermore, the valve 13 is a back pressure valve, which has a pressure relief through hole located above the water receiving tank, so that the water flowing out from the pressure relief through hole flows into the water receiving tank 172 and is injected into the groove 151 through the other part of the additional water discharging part 1721. Specifically, the back pressure valve has a back pressure cavity filled with water to form back pressure. When the water inlet valve 10 intakes water, the pressure relief through hole is opened, and the water in the back pressure cavity flows out from the pressure relief through hole and flows into the water receiving tank 172, and is injected into the groove 151 through the water inlet end of the other part of the additional water discharging part 1721;
[0036] The water inlet valve 10 includes a valve seat 14. The valve 13 is detachably arranged in the valve seat 14 for easy maintenance of the valve 13. Specifically, a clamping block is arranged on the valve 13, and a clamping groove is arranged on the valve seat 14. After the valve 13 is placed in the valve seat 14 and rotated, the valve 13 is hermetically clamped in the valve seat 14.

These drawings are part of the disclosure of the present utility model, mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.
