TECHNICAL FIELD

[0001] The utility model relates to the technical field of anti-siphon part, specifically to a water supply tank's anti-siphon part. BACKGROUND

[0002] Because the liquid is faster and faster when flowing in the pipe, the low pressure area is formed in the pipeline, and then the siphon phenomenon is formed, which is usually caused by the pressure imbalance between the pipeline and the water tank. If it is not solved for a long time, it may cause the water pipeline to break, leak and other situations, increase the maintenance cost, and also affect the water quality safety.

[0003] The anti-siphon part of most of the existing water supply tank is relatively complex in structure, and needs to be driven by electricity during use. After long-term use, it needs to be maintained regularly. For many water supply tanks that are not easy to open, it is very inconvenient to maintain the anti-siphon part inside. Based on this, the utility model designs a water supply tank's anti-siphon part to solve the above problems. UTILITY MODEL CONTENTS

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model uses a floating plate to move the inlet pipe with the water level, avoiding the siphon phenomenon caused by the large pressure difference between the pipe and the water tank after the water is pumped out due to the inlet pipe being inserted too deeply. The structure is simple and convenient, does not require electric drive, reduces the cost of use, solves the problem that the existing anti-siphon components of the water tank are relatively complex and inconvenient to maintain, and improves the practicality of the anti-siphon components and the convenience of maintenance.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an anti-siphon component for a water tank, including support rods 1. The tops of two support rods 1 are symmetrically fixed to the bottom surface of a fixing plate 2, and the bottoms of the support rods 1 abut against the bottom of the water tank. Float plates 3 are slidably fitted onto the two support rods 1. The float plates 3 have symmetrically opened sliding holes 11 that cooperate with the support rods 1. A water inlet pipe 4 is fixedly connected to the bottom surface of the float plate 3 away from the support rods 1. The height of the water inlet pipe 4 is 5-10mm, ensuring that the water inlet pipe 4 can be inserted into the water surface inside the water tank, while preventing siphoning caused by excessive pressure difference between the water pipe and the water tank. A connecting pipe 5 is fixed to one end of the water inlet pipe 4 extending to the top surface of the float plate 3, connecting... A connecting cap 6 is threaded onto pipe 5. A supporting connecting pipe 7 is fixed through the end of the connecting cap 6 away from the floating plate 3. Fixed flanges 10 are fixed on the outer surfaces of the supporting connecting pipe 7 and the telescopic connecting pipe 8 on opposite sides. The two fixed flanges 10 are fixed together by bolts and nuts. A telescopic connecting pipe 8 is fixed to the end of the supporting connecting pipe 7 away from the connecting cap 6. A sealing ring is fixed to the side of the telescopic connecting pipe 8 facing the fixed flange 10. A sealing groove that mates with the sealing ring is opened on the top of the supporting connecting pipe 7 to ensure the sealing of the connection between the supporting connecting pipe 7 and the telescopic connecting pipe 8. A connecting pipe 9 is fixed through the end of the telescopic connecting pipe 8 away from the supporting connecting pipe 7. The connecting pipe 9 is threadedly connected to the drain outlet at the top of the water tank.

[0024] In use, after installing the support rod 1 and the float plate 3 inside the water supply tank, the connecting pipe 2 9 is connected to the drain outlet at the top of the water supply tank. After connection, under the action of buoyancy, the float plate 3 always floats on the water surface of the water supply tank, so that the inlet pipe 4 can always be inserted into the water surface by 5-10mm to ensure normal water pumping. As the water level drops, the float plate 3 drops, and at the same time, it drives the telescopic connecting pipe 8 to stretch and unfold. When adding water into the water supply tank, the water level rises, and the float plate 3 rises with the water level. At this time, the telescopic connecting pipe 8 retracts. When replacing the telescopic connecting pipe 8, the nut at the bottom of the telescopic connecting pipe 8 and the connecting pipe 2 9 can be turned off to disassemble the telescopic connecting pipe 8 for replacement.

[0025] Please see Figures 1-4 A limiting plate 13 is fixed to the top of the fixing plate 2. A fixing pad 12 is fitted on the fixing plate 2 and the limiting plate 13. A fixing groove 14 is opened inside the fixing pad 12 to cooperate with the fixing plate 2 and the limiting plate 13. The fixing groove 14 is T-shaped to cooperate with the fixing plate 2 and the limiting plate 13. The top surface of the limiting plate 13 is flush with the top surface of the fixing pad 12. Fixing holes are opened inside the fixing pads 12 on both sides of the fixing groove 14.

[0026] When it is necessary to replace the support rod 1 and the float plate 3, open the water tank, release the fixing between the fixing plate 12 and the inner wall of the water tank, then pull out the support rod 1, the fixing plate 12 and the float plate 3, remove the float plate 3 from the support rod 1, and then remove the fixing plate 12 from the support rod 1. The support rod 1 and the float plate 3 can be replaced separately. After the replacement is completed, pass the support rod 1 through the fixing plate 12 so that the limiting plate 13 and the fixing plate 2 are engaged inside the fixing plate 12. Slide the float plate 3 onto the support rod 1, put the support rod 1, the float plate 3 and the limiting plate 13 into the water tank, and fix the fixing plate 12 to the tank body with bolts. At this time, the limiting plate 13 and the fixing plate 2 are engaged inside the fixing plate 12, and the fixing plate 12 and the support rod 1 can be fixedly connected.
